How to clear memory on Android from unnecessary files. How to free up internal memory on Android in different ways? Release the inner

Unlike the iPhone, which has no removable cards and all the memory is built-in, most devices equipped with Android allow the use of memory expansion modules. But you cannot transfer the OS to them; they are only suitable for storing user files.

Therefore, system memory is considered one of the weakest points of the Android OS. It fills up over time, depending on how the user uses the device. different files, among which there is also garbage. And in this case, you have to clean the system.

How to free up internal memory on Android

Applications, reports (logs) and system cache are stored in the built-in memory. One of the options for freeing it is, but this is not always possible, some of the data must remain in the system partition, this is necessary for correct operation.

Available methods:

1. Move programs using standard means Android. Find the desired program in the “Applications” item in the device settings and click “Move to SD card”. In this simple way, you will free up the space in the internal memory of the device that was occupied by a specific program.
2. Another way is simple removal applications, this can be done through the task manager or the “Applications” menu from the previous paragraph. The exception is preinstalled programs, using standard methods which cannot be uninstalled. In this case, you will need root rights. Next, you need to go to the system/app folder and delete the same apk and odex files of unnecessary program, but be careful because some of them, such as Google services, affect other programs. Only experienced users are allowed to do this.
3. Periodically you need to clear the cache and temporary files; this is best done using special applications, which will be discussed below. But you can also perform the procedure manually by selecting the “Data Clearing” item in the program menu. In some ways, this option is safer, but much more labor-intensive.
4. There is a cleaning method using a file manager. It seems that everything is very easy here - you just need to delete files, but this is not true. If there are no root rights, then you won’t be able to erase anything important, but when granted full access(third-party managers often use it) you need to be careful. Before carrying out the procedure, it is better to create a system save and place everything on another medium.
5. As an alternative, you can use cloud file storage. This means that you will always have access to them via the Internet. There are many services, one of the most popular is Dropbox, which has its own mobile application. You can also save notes or documents to Evernote at no cost if your device doesn't have data restrictions.

How to free up RAM on Android

This is a special section of the smartphone’s memory; the amount of RAM cannot be combined with memory cards, and you cannot record a movie or game there. It is needed to store application data. After the job is completed, the memory is freed, but many programs continue to run in background. Sometimes such a function is really necessary, but in most cases you can do without it.

1. The easiest way to clean random access memory– turn off programs rather than minimize them with the Home key. But, unfortunately, many developers simply do not provide such a function in their applications or it is difficult to find. Sometimes pressing "Back" several times helps, but nothing is guaranteed.
2. Another way is to force stop the most resource-intensive applications. The list is available in the “Applications” item, which can be found in the settings. The “Running” tab displays all programs, except system ones, that are running in this moment, on the right is the amount of memory they occupy. Just check the box next to the desired application and click “Stop” (button below), but in this case, unsaved information may be lost.

The most radical way to solve the problem is to reboot the device.

Using special programs

An example can be given. This is perhaps the most popular app for system maintenance. Of course, there are other programs with similar functionality, but you should understand that the main thing here is to do no harm. If important files have been deleted, it is not always possible to restore them. The consequences of poor cleaning can be disappointing, so it is better not to experiment with little-known applications if there is no copy of the system.

To use, you will need to provide the application with root rights, they give full access to file system, with the ability to change the content. The application itself will send a request or provide instructions on how to do this.

The interface is completely Russified, so even inexperienced users should not have any difficulties when using it. You just need to start the scan; after it is finished, you will be asked to clear not only the cache files, but also the space in RAM that is used by inactive applications.

Another type of analysis is also available: applications that are rarely used will be found and their uninstallation will be suggested. In this case, you still shouldn’t blindly trust the program, it’s better to visit Play Market and find out what they are for, perhaps some of them will still be useful to you.

The application also has other functions: in particular, cooling and analysis of battery usage, but they will not be discussed in detail here.

It is worth noting that the application itself works in the background, constantly analyzing user activity and offering various tips. Sometimes this can negatively affect performance and negate the entire cleaning effect.

As an alternative, we can offer a less resource-demanding App Cache Cleaner app, but its functionality is highly specialized.

There are two symptoms when the internal memory on the phone is sorely lacking:

1. Applications and Android are slow,
2. The phone displays a message that you need to take action and free up the occupied space.

The internal memory of the phone has a fixed volume, and it (seemingly) cannot be increased. However, in the guide we will tell you how to clear the internal memory of your phone from unnecessary files and applications.

By increasing the free space in Android memory, you will save time and stop noticing lag on your phone and tablet. The entire “cleaning” will take about 20 minutes.

Error: Insufficient memory on mobile device

Android usually displays this message if a process or application is missing free space in the phone's internal memory.

Lack of memory can make itself felt by constant freezes. If this is not noticeable when buying a phone, then over time, after installing dozens mobile applications and the accumulation of “garbage” you begin to notice it.

The question involuntarily arises: do the phone’s characteristics “lie”? If not, then why does the same smartphone/tablet work stably for others?

Checking the amount of free memory on Android

When a notification appears about insufficient internal memory, the question arises: how much memory is available, what part of it is occupied?

You can check your free space through settings mobile phone. To do this, go to Settings – Options – Memory (Settings – Device Maintenance – Storage – Storage settings – Device memory). We carefully study the data, paying attention to the following figures:

• Total space – the amount of internal memory of Android
• System memory - the minimum amount of space reserved for system operation
• Available space – how much space is left in the internal memory.

Accordingly, if the built-in memory is not enough, you need to increase the memory on the phone to the size of System memory so that the system does not display the corresponding error.

In the following chapters, I will tell you how to clear the internal memory on Android.

Clearing your phone's internal memory

You can remove unnecessary things through the built-in tools of the operating system and through third-party applications. They analyze occupied space and help identify files that can be safely deleted.

Removing applications from Android system memory

There are probably applications installed on your phone that are hanging around like dead weight and are not being used for their intended purpose. Their size can reach hundreds of megabytes (including cache).

You can remove useless programs through the standard Application Manager: Options - Settings - Application Manager (Settings - Apps).

In Android 8 for calculation unnecessary applications It is convenient to use the free FIles Go utility. For other OS versions it is available for download via Google Play.

How to remove unwanted apps in FIles Go:

1. Go to the Unused apps section,
2. We sort applications by modification date or size,
3. To delete, mark unnecessary programs check the boxes and click Uninstall.

Video instructions for deleting applications:

Transferring files to a memory card

The internal memory of the phone, as already mentioned, has a fixed volume, so you need to constantly check whether there is enough free space for applications and the OS to work correctly.

In general, Android memory is divided into internal and external. External memory is easy to “expand”, fortunately, SD cards are inexpensive today (for $25 you can buy a 256 GB memory card).

Actually, you can transfer files through any file manager– via phone or PC.

Moving unnecessary applications from internal to external memory card

Removing unnecessary files using Piriform CCleaner

As an alternative to CCleaner, it is convenient to use the aforementioned Files Go application.

How to increase memory on Android manually

To manually clear your phone's memory, any file manager will do. We recommend ES Explorer or Total Commander.

Be careful and delete only unnecessary user files in Android's internal memory that you created/copied yourself.

So, open the file manager, go to the root of the internal memory, start searching and deleting what is unnecessary.

Which files should you delete (transfer to a memory card) first:

1. Photos, videos, voice recorders and other documents saved not on SD, but in internal memory;
2. Documents received by mail or via social media(most often they are saved in the Download folder);
3. E-books and other files saved third party applications to the device memory;
4. Contents of folders DCIM, bluetooth, sounds.

We use Storage Analyzers (for clarity)

For clarity, we recommend using the Files Go application or any other storage analyzer for Android, which will show which files take up the most disk space and where they are located in the form of a diagram. Among these applications we note:

Transfer photos and videos to Google Photos service

It is photos and videos that “eat up” the most space on your phone, so you can quickly free up space on your memory card or built-in storage. If your phone doesn't support a memory card, move files you don't access often to the cloud. The best app for this is Photos, or Google Photos. It automatically uploads photos to the service, where they are available in their original quality through a browser or application.

In addition to Google Photos, you can pay attention to alternatives such as Dropbox, Flickr or Microsoft OneDrive.

Even when the photos are only available on the server, you can easily access them if you have a working internet connection. And most importantly, it is really convenient and quick way free up a couple gigabytes of internal memory!

Memory clearing: questions and answers

1. The phone did not have enough internal memory, I sent half of the photos to the SD card, after that I open it, and they are all kind of cloudy. I tried to transfer it back to the internal memory of Android, but the photos are the same. How can I get my old photos back? so that it is as before, cleaned up without any distortions.

2. I didn’t have enough internal memory on my phone, so I wanted to clear it. I transferred the data (photos, music) to the memory card. Now the files cannot be read, although the phone sees the card. How can I get at least a photo back?

3. Samsung A5 phone. I didn’t know how to increase the internal memory, so I used my laptop to move folders with music and files from the internal memory to an SD card. After that, when opening the folders, they all turned out to be empty. Neither the phone nor the computer can see the files and music. The internal memory of the phone did not seem to decrease after this. How to find these files?

Answer. You probably copied sketches, not originals, to the memory card. The original photos may have remained in the phone's internal memory. If this does not happen, the DiskDigger program will help you.

If there is not enough space in the device memory, you should copy the files to your computer (make backup copy) and only then move it to the memory card. It will be useful for you to read the instructions on how to clear internal memory on Android (see text above).

I have Sony phone Xperia, when I go to the Play Market, I want to download some program, the system says that there is not enough memory on Android, although the flash drive is 16 GB! What to do?

Answer. Most likely, the “insufficient memory” error on Android is due to the fact that there is not enough internal memory - this is where the installation files are downloaded from Google Play.

1. Transfer the largest files from the internal memory of Android to your SD card.
2. Remove unnecessary applications using a file manager or Files Go.
3. Use the CCleaner utility to clean up unnecessary files in your phone's memory.

I cleaned my phone's memory and deleted many folders. And now I can’t view the gallery through Android, it says: “The storage is not available.” How can I get it back?

Answer. During cleaning, you probably deleted the folder with photos on the memory card (SDCARD/DCIM/CAMERA). You can recover files from there using CardRecovery or PhotoRec programs.

We use smartphones every day and over time, the internal memory runs out and it becomes impossible to record new files. In such situations, as well as as a preventive measure, it is necessary to clear the internal and RAM memory. This can be done using the capabilities of the smartphone OS itself, using special programs, or by connecting your mobile device to your computer. Let's look at the main ways to free up memory on Android.

When actively using a mobile phone, it is necessary to clear the internal memory from time to time. Even without writing new data to your smartphone, the space in the internal storage becomes clogged with the cache of applications, browsers and other garbage. This leads to the fact that you cannot install a new game from the play market on your phone or download your favorite movie to watch. In addition, clogged memory can cause system slowdowns and glitches. So how do you clear your internal memory? Let's look at the main methods, with and without a PC.

Saving files to a microSD card

Before you clear the free space of the internal storage on your tablet or smartphone, you must prevent it from loading further. To do this, you will need to set the settings of the following applications to save the created files to the memory card:

• Camera.
• Dictaphone.
• Internet browsers.
• Various applications in which data is created, edited and saved.
• Mobile messengers in which multimedia files are exchanged (Skype, Viber, etc.).
• Downloaders of music, pictures, films, torrents.
• GPS maps, navigators.

Now the created files will be automatically saved on the microSD card, thereby not filling up the internal memory of your phone.

Move to microSD card without PC

To move files without a computer, you will need an installed explorer - a file manager. In some models of Android smartphones and tablets it is installed as standard software, but in most cases it must be downloaded separately. One of the most functional and convenient file managers, which can be downloaded for free from the play market, is the ES Explorer utility. Its main advantage is the ability to select and set an action for several folders or files at once.

To move files in Explorer, you need to select them with a long press. Note that to select multiple documents you need to check the boxes next to their names. After selecting the files, you need to click on the “more” tab in the lower area of ​​the screen, and in it select the “move to” item. Next, you need to select the path to the SD card, create or use a pre-created directory on it.

Moving from Android using a computer

To transfer files from the internal memory of your mobile phone to an SD card or any other external storage device, use a computer. To do this you will need:

• The Android smartphone or tablet itself.
• Computer with Windows or Mac OS.
• USB cable.
• Your drivers mobile device And so on software installed on a PC.

After connecting your mobile phone to your computer, you need to select the “data transfer” connection mode. After this, the internal memory and SD card files will be displayed as a separate partition on the PC. They can be moved, deleted or copied just like any other files on your computer, freeing up space on your mobile phone’s internal storage.

If you are uncomfortable connecting your phone to your PC all the time when USB help cable, you can use free service AirDroid. It allows you to connect Android to your computer both remotely and while in the same wireless Wi-Fi networks. In this case, the user also gets access to files stored in the internal memory of the mobile phone. All you need is free access to the Internet for both devices and any browser through which you can manage your phone files from your PC.
You can familiarize yourself with setting up the AirDroid service and its main capabilities in the video below.

Transferring apps to a microSD card

Probably many have noticed that applications and games on Android are mostly installed in the internal memory. To put them on a mircoSD card you may need root rights access. After they are received, you need to install the Link2sd utility. With its help you can also transfer to a memory card before installed applications and games. But it is worth noting that this may affect their operation, as well as the stability of the operating system as a whole.

Some apps and games can be transferred to microSD card and without administrator rights. To do this you need to download from the play store Android utility Assistant. It includes 18 tools for managing Android OS. After launching it, you need to go to the “Toolkit” tab, and in it select the “App2Sd” item. In the list of applications that opens, you can select several at once to move them to the map. This way, you can clear Android's internal memory without deleting files.

Deleting files and cleaning up junk

You can delete applications from your phone's storage directly from the settings menu. To do this, you need to select the appropriate item, and then go to the properties of the selected program. To delete other files, you will need a file manager. In it, you can open any directory in the internal memory of your mobile phone and delete documents manually.

Cleaning your phone of junk: Internet browser caches, applications, registry files is getting rid of unnecessary data. For this, special utilities are used, for example, Clean Master. The advantage of this program is its maximum simplicity and ease of use. To clean, simply click on the appropriate button in the menu. In this case, the utility will scan all memory for garbage and present the cleaning results on the screen.

Using cloud storage

And the last way to free up space in the internal storage of your mobile phone is to use cloud storage. With a stable Internet connection, you can safely store files on: Yandex disk, google drive, [email protected], etc. The advantages of this method include the ability to access information from different devices and reliability of file storage.

Freeing up RAM

RAM plays a vital role in the multitasking of a smartphone or tablet, the ability to open several Internet browser pages at once, etc. Background processes, installation of programs, as well as additional widgets load RAM. As a result, even the most advanced smartphone models are faced with a lack of RAM and reboot. Let's look at several ways to clear RAM that will help your phone work more efficiently.

Using OS features

Most manufacturers provide their phones with a special utility that allows you to clear RAM. It can be called differently, but most often: clean or purification. Just click on it and the utility will automatically unload unnecessary programs and widgets from the RAM.

Via Application Manager

Used RAM

For this method you will need to enter the menu system settings mobile phone Next, go to the “applications” item and select “working”. This tab displays information about which programs and processes are open and running at the moment, as well as how much RAM they are consuming. Before closing them all, you need to see what can be removed from the list of background processes so that the system does not crash. In most cases, desktop services, various launchers, etc. don't touch it.

Using special utilities

The simplest and reliable way cleaning RAM is using special utilities. We have already discussed one of these above, this application - Clean master. By launching it, you can choose not only to clear the internal memory, but also the RAM. To do this, click on the corresponding icon on the main screen, and then click on the “Accelerate” item. In this case, information about the amount of freed RAM will be displayed.

The memory full problem, which can be identified by the message issued by the Android operating system “Memory Full,” is quite common. Moreover, there are no universal solutions for it, but there are many tips. In this material we will try to systematize all, or at least most, of the available information on this issue.

Types of memory in Android devices

RAM, Random Access Memory or RAM - random access memory or random access memory. The software (including the operating system and installed applications) writes to given memory the data they need during their work and can quickly read it. RAM requires constant power - when you turn off or restart the device, it is completely cleared. The more RAM, the correspondingly more different processes and services can be launched simultaneously. The “Phone memory is full” error may occur if the entire amount of RAM is completely exhausted, and there is not enough free space for the application being launched.

ROM, Read Only Memory or ROM - read-only memory. The information stored in it cannot be changed and is recorded when the phone is manufactured, or when the operating system is reinstalled - that is, during the flashing process. ROM is often divided into several sections to perform internal functions.

Interal Storage (Interal Phone Storage) – internal storage of a smartphone (or other device). This memory section is designed to store user data, installed applications, and so on. This is something like an analogue of a hard drive in a personal computer. Naturally, in the process of writing data to the internal memory of an Android device, the free space here becomes less. The total storage capacity and the amount of free space can be viewed in the device settings.

External Storage – or, essentially, a microSD/microSDHC memory card. This type The user can expand the memory at will, if, of course, the device supports memory cards, and there is a corresponding slot for this. Is something like external hard drive For personal computer. The total and occupied volumes of this type of memory, as well as the free space on the card, can be checked in the settings of the Android gadget. You can store multimedia data such as music, movies, pictures on a memory card. Starting with Android 2.2, it became possible to transfer installed applications to a memory card if the application itself supports it, thus saving space on the internal storage. Before replacing a memory card, it is strongly recommended that you first unmount it rather than simply removing it from the device.

Why does memory run out?

Usually, after some time of relatively “quiet” use of a device on Android, users begin a period when they want to modify this very device in every possible way programmatically. The endless installation of applications, scripts, and so on begins. And sooner or later the message “Phone memory is full” appears, especially if the model is not one of the “top” ones, and there is not that much memory. It is logical to assume that the problem is in RAM - yes, this is partly true. But cleaning it up is much easier; this can be done both through the settings and using various downloadable utilities. So, a message about a lack of memory in the device appears when the internal storage is full. Of course, you can constantly clean this very drive, remove unnecessary applications, and so on, but over time it will be seen that the notorious “Phone memory is full” will appear more and more often. What is this connected with?

• The Android operating system installs applications to internal memory by default;
• Not every application can be transferred to a memory card;
• “hard-wired” into your device is vital important programs like Google Maps and Google Play are updated periodically, occupying additional internal memory cells;
• Some manufacturers load up the smartphone or tablet you buy with pre-installed games and other software called bloatware.

Checking free space

Via dispatcher

IN Samsung devices Press and hold the Home button for about a second, then go to the memory icon.

The data here is displayed in the format "Occupied/Total", so you will need to remember a little arithmetic lessons.

Through settings

Everything is simpler here: Settings > Options > Memory . And you don’t need to count anything.

How to clean - overview of options

Operational measures

For a quick, although not very long-term, solution to the situation, clearing temporary files will help. They have the extension .rm and are stored in the folder datalocal mp. You can delete temporary files if you have Root access, for example, when Root help Explorer.

Also, in the above folder data you can find many files that have the extension .log and contain “error” in the name - these are log files of errors from various applications that take up quite a lot of space. We delete them and forget about “Phone memory is full” for a while.

Removing dex files

Now let's look at a more thorough method of cleaning space on the internal drive. Each program on a smartphone or tablet, or any other Android device, when installed, creates a file with the extension .dex in the directory datadalvik-cache. But sometimes, on some system applications these files are missing, and the following picture is visible:

It's really strange that the program takes up 0 bytes. As it turns out, the reason lies in the fact that along with these files, the firmware contains files of the same name, but with the .odex extension. These files can be created, and then there is no need to leave the .dex files. For example, LuckyPatcher can “oddex” applications. So, first, look in the application properties to see how much space it takes up:

In this case it is 1.68 MB, so the corresponding .dex file is in datadalvik-cache takes up the same amount of space, and the created .odex file will weigh the same. Launch the mentioned LuckyPatcher, select from the list the right application, press on it (not just “tap” once, but press and hold), we see the context menu:

We select the first or second item, and it does not matter that the application may not need to remove license verification or remove advertising at all. After this, the program will create the .odex files we need. You can now remove .dex files from datadalvik-cache. And now we see that the application already takes 0 bytes, but it works fine. This method suitable for system applications.

For custom applications, everything is a little different. We select the application we need and go to its folder on the memory card, look at the free memory of this application. In this example, 1.56 MB is reserved for the program folder, while the .dex file occupies 1.68 MB.

There are several ways to solve this problem: either move the selected application to the system directory and carry out the manipulations described above, or forget about this idea specifically with this application and take on some other program. By the way, if you move the application to user memory and then create .odex, you can delete .dex, and the program will work normally. But when you move it to a flash drive, the .odex file will be deleted and the application will refuse to work. In this case, there are only two options left: reinstall the program again or do a complete clear of dalvik-cache. So not every application can work without .dex - the method will only work with applications that have more free memory than .dex.

Hard reboot

You can solve the problem radically by using Hard reset– hard reboot of the communicator. This is a good step, returning the device to its original factory settings. The speed of operation increases, the smartphone instantly responds to all input and literally begins to “fly”. But, on the other hand, such an action can cause inconvenience for the user, because this is the deletion of data, files, applications that he will be forced to install again.

Removing unnecessary applications, their updates and cache

To get rid of unused apps, go to Settings > Options > Application Manager.

Once in the “Downloaded” tab, call up the menu and sort the files by size. Next, select the applications you abandoned and click “Delete”.

You can only remove updates from applications that you installed yourself—this trick won’t work with built-in ones.

Select the application, click on “Uninstall updates”, and then click on “Disable”.

If you have root, then you can even get rid of system software. But be careful - one awkward move, and your smartphone will fall asleep.

To clear the application cache, go to: Settings > Options > Memory.

Wait a few seconds until the amount of occupied space is determined, then select “Cached Data” and tap “OK”.

Using CCleaner utility

I can’t say that this method is super-effective, given that some utilities themselves take up a lot of space and even display advertising. Therefore, if you decide to resort to it, then choose the proven CCleaner.

After the utility has done its job, you can safely remove it until the next need.

Video: How to free up memory on Android

“Phone memory is full” is certainly one of the most unpleasant and annoying messages for Android device owners. We hope that thanks to our advice, she will not bother you for a long time.

Often faced with the problem of memory overflow. There is probably no universal recipe for solving this problem, although you can look for some practical advice, although they are not systematized. Let's try to understand this issue and find out how to free up internal memory on Android.

Types of storage devices

So, first you need to understand what kind of devices are found in devices with the Android operating system. You need to know this in order to better understand the essence of the problem and what needs to be done about it.

RAM, RandomAccessMemory or RAM

This is the so-called RAM. This is where the operating system and software Android systems they record all the necessary data for the smooth operation of the application; by the way, they calculate it quite quickly. It should be taken into account that when the device is turned off or rebooted, the RAM is quickly cleared; the RAM necessarily requires constant power.

Well, and, accordingly, the more memory, the more services and applications can be launched simultaneously on the device. The amount of memory also determines which resource-intensive applications can be run on your phone. When all the RAM is exhausted and there is not enough space for the new app you are trying to launch, the “Phone memory is full” error may appear. In principle, technology does not stand still, and already with Android versions 2.2 and higher, the operating system itself determines what needs to be removed from memory, which applications can be closed in order to free up space. Today, many flagship devices have sufficient memory of 1 Gigabyte. There are even 2 Gigabytes. Therefore, the question of how to free up internal memory on Android 4.1.2 arises less often than in relation to more earlier versions. If we look more at Android, tablets and smartphones, then they basically have 512 MB or a little more than 768 MB (quite a non-standard size).

In fact, progress does not stand still, everything is improving, because just a couple of years ago, most Android devices had only 256 Megabytes of RAM and instructions on how to free up internal memory on Android 2 were quite in demand.

ROM, ReadOnlyMemory or ROM

It is read-only. What is stored in it does not change and is recorded at the factory or when it is reinstalled operating system, when flashing. The ROM is divided into sections to perform various internal functions.

Interal Storage (Interal Phone Storage)

The internal storage itself. This is where all the data and applications that the smartphone user enters are stored and tablet computer. An internal drive is an analogue of a hard drive in a personal computer. Of course, when we record various applications on the device, the memory decreases, and increasing it is not difficult - just remove the unnecessary ones. You can find out the volume of the built-in storage and the availability of free space by seeing them in the device settings. Thus, often the answer to the question of how to free up the internal memory of Android is to clear the internal storage.

or ExternalStorage

This is the so-called removable memory. The capacity of the memory card depends on the card you choose; however, you must take into account whether your device has the necessary slot and whether the device supports it. ExternalStorage can be compared to an external hard drive for a personal computer. And the amount of free space and occupied space can also be seen in the settings of your gadget. This card is good for storing multimedia data: music, movies, photographs, pictures. By the way, already with Android 2.2 and higher, you can transfer all applications installed by the user to a memory card, this significantly saves space on the internal storage. If you decide to replace the memory card, then do not forget to unmount it first, and only then remove it.

Android smartphones: how to free up internal memory?

Many users, after becoming more or less accustomed to their gadget, begin to install and stuff their device with various applications, scripts, and modify programs in every possible way. And someday the message “Phone memory is full” will still appear, especially if the model is not the most expensive and does not have much internal memory. Part of the problem lies in the RAM. It is very easy to clean it - through the device settings or download an additional utility. So, when the gadget’s internal memory is full, a message will appear indicating that there is not enough memory. In principle, you can constantly clean your internal storage and delete applications that you no longer use, but the time will come when this message will appear more and more often. Quite a lot of space is taken up by various updates that come to GooglePlay. By the way, you can transfer some programs to a memory card using a special program Link2SD. Access to InternalStorage is obtained with Root rights. These actions are also a good memory clearer. You also need to clean up the so-called ones, they have a .rm extension, are stored in the datalocalmp folder and are constantly accumulating. For this action, you also need to have Root access and resort to the help of RootExplorer, plus files with the log extension are often accumulated in the same folder and contain error in their name - these are application errors, they also take up a lot of space. All these unnecessary files must be deleted.

What measures are best to take?

But this is all temporary cleaning of the device. What is a more thorough way to free up internal memory on Android? When installed on a smartphone with an Android device, each program creates a file with the .dex extension in the datadalvik-cache directory. True, it happens that some system applications do not have such files.

It may seem strange that this program does not take up space. However, the reason is that along with these files in the phone’s memory there are files of the same name, but with the extension .odex. In principle, such files can be created, then there is no need to leave the .dex files. To do this, you can install an additional application, for example, LuckyPatcher.

Now let's proceed directly to the steps that will help answer the question of how to free up internal memory on Android 2.3.6 and newer versions.

Let's see how much space the application takes up - the "Properties" menu.

For example, this is 1.68 Megabytes, and, accordingly, the dex file takes up the same amount of memory, and the odex file that we created will “weigh” the same amount. Now you need to launch the LuckyPatcher application and select the desired application from the list. We press (hold, not just click). It turns out you need to select the first or second item. The program itself will create the odex files we need. Then we delete dex from the datadalvik-cache folder. Now the application works fine and takes up 0 MB. This way you can free up memory for all system applications. This is how you follow the instructions on how to free up internal memory on Android 4.0 and other distributions.

A slightly different method is suitable for cleaning user applications. We selected an application, went to its folder on the memory card, we see the free space of this application. For example, there is 1.56 MB of free space left, and the dex file takes up 1.68 MB. You can, in principle, move the desired application to the system directory and do the same as mentioned above, or simply select another application and leave it as is. By the way, if you still move this application into user memory and create an odex file and then delete the dex file, then the application will work fine. But if you transfer it to a flash drive, the odex file will be deleted and the program will not work, then you will have to either install it again or completely clear the dalvik-cache. Please note that, in general, not every program will work without dex files. This is typical for games or applications with a dex of up to 1.5 Megabytes. This method is suitable only for those applications that have dex files less than the available memory space. As you can see, the steps to help answer the question of how to free up internal memory on Android are not particularly difficult.
