Samsung s7 network disappears. Samsung Galaxy S7 won't turn on - what to do. Clearing the cache

As always, we'll assume that the Wi-Fi hotspot you're trying to connect to is working fine. If this is not the case, then:

• A common cause of the problem is Bluetooth is turned on, operating at a frequency of 2.4 GHz. You can also change the Wi-Fi frequency range from 2.4 GHz to 5 GHz;
• Get closer to the point, then turn off and turn on Wi-Fi on your smartphone again. This is especially useful when using a public hotspot. You can also use a program like Wifi Analyzer to find the least busy channel;
• Activate menu quick access and hold down the Wi-Fi button to get to the settings menu. Find the problematic network, press and hold it and select “Forget network” in the pop-up menu and restart Wi-Fi;
• On the menu Wi-Fi settings select "More" in the upper right corner. There you will find the Smart Network Switch option. Make sure it is disabled;
• It is also worth clearing the partition cache. To do this, activate the control menu by holding down the Power, Volume and Home keys, and select the wipe cache partition item. Then restart your smartphone;
• If the problem is that Wi-Fi is constantly turned off, go to the Wi-Fi settings and set Always in the Smart network switch column;
• The last resort is a factory reset.

7. The camera does not work

If, when you try to launch the camera on your Galaxy S7, the message “Warning, Camera failed” appears, do not rush to run to the workshop. This problem can be solved simply:

• Restart your smartphone;
• Go to Settings > Applications > Application manager > Camera app and select Force Stop. Then go to Storage > Clear cache and clear the cache;
• There may be a problem with Smart Stay. Try turning it off in Settings > Display. · Clear the partition cache through the management menu (see point 5).

Galaxy S7 has outstanding performance. But some note that at times the smartphone wakes up very slowly. In such cases:

• Reboot your device. This usually helps, but only temporarily;
• Check the authenticity of the microSD card. A counterfeit memory module has a detrimental effect on the performance of any smartphone, so be careful when purchasing. Especially if you order online. The main methods for identifying counterfeits are described in this article;
• If the card is genuine, try formatting it;
• In some cases, resetting the smartphone to factory settings helps. Before this, you need to transfer all data to another medium and remove the microSD card. To reset the settings, go to Settings > Backup and reset > Factory data reset.

9. Battery drains quickly

Like most smartphones today, the Galaxy S7 has built-in batteries. This means that it will not be possible to replace them like with the LG G5. On the other hand, rapid battery discharge is not always caused by problems in the battery itself.

And before going to the service center, try the following options:

• Reduce time automatic shutdown screen. This can be done in Settings > Display > Screen timeout. It would also be a good idea to check when the screen turns off. This is especially important for owners of wallet cases. It happened that the screen simply did not turn off and had to be done manually;
• Disable the Always On feature in Settings > Display;
• Go to Settings > Battery > Battery usage and check the battery consumption of applications. If one of them consumes too much energy, most likely it is the culprit of the discharge;
• Clear the partition cache. To do this, activate the debug menu by holding down the Home, Power and Volume keys, and then select wipe cache partition. Navigate through the menu using the volume key. Select - power key;
• The last resort is to reset your smartphone to factory settings.

Problem 4: Palm Detection doesn't work

The “Palm Detection” function allows the display to ignore accidental clicks on it, although in some cases it fails: even a light touch or simply holding the smartphone in a certain position can be interpreted by the device as pressing the screen.

Make one long press on an empty area of ​​the display, then swipe to bring up Briefing and turn it off to improve system performance.

Problem 8: Battery drains quickly

Often the culprit behind sudden, catastrophic battery drain is an app, so you may want to close all apps or reboot your device to see if the situation improves. Use the notification panel to turn off any features you don't need. Also use the “Background Data” item from the “Data Usage” section to stop applications that use your Internet channel and, plus, turn off the screen.

Problem 9: The device is getting too hot

If your Samsung Galaxy S7 Edge gets as hot as a stove while running, there are a number of steps you need to take. If this happens when charging the device, then try not to use it at this time, and also disable the “ Fast charging via cable" in the "Battery" section.

Additionally, you will need to check the applications for any "wrong" application. Go to “Settings>Battery>Battery Usage>Advanced” and open “Optimize Battery Usage”. Here you can select All Apps to make sure no apps are draining your battery while running. background. If heating is observed at the end of the cable, and not in the smartphone itself, then your cable is faulty. Our advice to you is to resist the temptation to use ultra-cheap chargers from little-known manufacturers and cables, including those from eBay, as there are many cases where they have caused excessive overheating and sometimes fires.
