1. We simultaneously press the power, volume up and menu buttons.
2. When a dark window appears, use the volume buttons to go down to the “hard reset” option and perform a reset.

Checking charging capability

When the device does not respond to turning on after charging, this may indicate loose contacts or a malfunction charger. To check it, just do any of the following:

• Check the memory on another smartphone. If it starts charging, then the problem is in your Samsung and you need to pay attention to the contacts inside the micro USB connector.

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.

1. Sound crackles or distorts

This usually happens due to faulty headphones or smartphone speakers. But before contacting the service center, try the following options.

2. No alarm sound

3. The smartphone shows a black screen without responding to keys

Some Galaxy S7 have a disgusting bug - the smartphone screen darkens and stops responding to touches.

In this case, the sound and backlight of the keys work as usual. Typically this will work for the service, but try these options first:

Samsung Galaxy S7 is the flagship of 2016 release. According to experts, the phone will not lose its relevance in the next 3-5 years - powerful dust and moisture protection, a modern camera, the ability to work under water... however, many owners do not turn on the Samsung Galaxy S7 after just a few months of use.

If guarantee period has already passed, and the phone suddenly turned into a “brick” - do not rush to despair. It is quite possible that the breakdown can be fixed on your own, even without a visit to the service center. In our article today we will tell you what to do if your Samsung Galaxy S7 does not turn on, how to avoid similar problems in the future, and provide general operating tips.

Samsung Galaxy S7 edge does not turn on after charging

Among the main reasons why the Samsung Galaxy S7 turned off and does not turn on, two can be mentioned:

1. the contact inside the phone has “lost”;
2. The charger/charging controller is faulty.

To check the functionality of the charger, simply try charging the phone with a different charger. If your Samsung S7 does not turn on even after this, you should change the battery. Of course, it is unlikely that it would be “exhausted” after a year of operation - but the cause could also be simple overheating. Remember the stories about S7 explosions while charging? The reason for this is constant overheating of the battery in some shipments of the flagship. It’s not surprising that the modern Samsung Galaxy S7 phone turned off and won’t turn on. Replacing the battery may well “revive” your phone - and the problem will go away.

Samsung Galaxy S7 won't turn on, blue light is on

After turning on, the blue indicator lights up, the word “Samsung” appears on a black background, and the boot process does not proceed further? We recommend trying a hard reset.

If your Samsung galaxy s7 has turned off and does not turn on, hold down three keys at the same time: Power, Volume Up and Menu. Hold them for a few seconds - a special menu should appear in which you need to select reboot.

If a hard reset with deleting all data from the phone did not help - the Samsung s7 edge does not turn on and after that, we advise you to take the phone to a good service center.

Perhaps flashing the device's firmware will help - the cost of such repairs is low, and the work is usually completed within 1-2 days after the request.

Samsung 7 age won't turn on after falling

Definitely, a visit to the service center is required. You won’t be able to work with the hardware yourself, and the amount of repairs depends on the consequences of the fall - if the touch screen bursts, then get ready to spend several thousand rubles.

Having “extended the life” of your smartphone, be more careful in the future - remember that modern technology “does not forgive” careless treatment!
