Samsung Galaxy S7 is the flagship of 2016. 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 operation.

If the warranty 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 eliminated on its own, even without a visit to the SC. In our today's article, we will tell you what to do if the samsung galaxy s7 does not turn on, how to avoid similar problems in the future, and provide general advice on how to use it.

Samsung Galaxy S7 edge won't turn on after charging

Among the main reasons why the Samsung Galaxy s7 turned off and does not turn on, you can specify two:

1. The contact inside the phone has "gone";
2. defective charger / charging controller.

To check if the charger is working, just try charging the phone with another charger. If your Samsung S7 does not turn on after that, you should change the battery. Of course, it is unlikely that he would have "worn out" for a year of operation - but the reason could be banal overheating. Remember the stories about the S7 exploding while charging? The reason for this is the constant overheating of the battery in some shipments of the flagship. It is no surprise that the modern Samsung Galaxy C7 phone has turned off and will not turn on. Replacing the battery may well "revive" your phone - and the problem will be gone.

Samsung galaxy s7 does not turn on blue light is on

After switching on, the blue indicator lights up, the inscription "Samsung" appears on a black background, and then the boot process does not go on? We recommend trying a hard reset.

If your samsung galaxy s7 turns off and does not turn on, hold down three keys simultaneously: Power, volume up and Menu. Hold them for a few seconds - a special menu should appear in which you need to select reboot.

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

Perhaps the firmware of the device will help - the price of such a repair is low, and the work is done, as a rule, 1-2 days after the call.

Samsung 7 Age does not turn on after a fall

Definitely - a visit to the service center is required. You will not be able to work with hardware on your own, and the amount of repair depends on the consequences of the fall - if the touch screen burst, then get ready for a cost of several thousand rubles.

By "extending the life" of your smartphone, be more careful in the future - remember that modern technology "does not forgive" negligence!

Video instruction

Periodically, problems with signal reception are noted at all mobile devices, and Samsung's Galaxy S7 series smartphones are no exception. Along with this, if such problems begin to appear with an enviable frequency, the user has to experience many problems and inconveniences. After reading the information below, you will find out why the Galaxy S7 can lose the network and what actions are available to the ordinary user to normalize the situation.

Reason one - failures in 3G

If you use a 3G network in regions where it appeared relatively recently, failures with a high degree of probability may appear due to problems in the network itself. The check comes down to a temporary transfer of the smartphone to 2G mode.

We do the following:

• go to the device settings;
• go to the Additional settings tab and find the item there Mobile networks;
• open the Network mode menu section and activate "GSM only".

You can do it differently:

• in the Settings menu we find the Connections section;
• go to the Other networks tab;
• select the Mobile networks section, after which in the Network mode tab we activate the previously mentioned item "GSM only".

We monitor the quality of network reception.

The second reason - failures in the network of a particular operator

Depending on the location of the subscriber, the network reception quality of different mobile operators may vary. To check the presence / absence of a problem on the part of the service provider, it is enough to insert a SIM-card of another mobile operator into the smartphone.

If the signal reception situation has returned to normal, the cause of the problem and the ways to solve it become obvious.

Reason three - outdated software

Samsung releases software updates regularly to fix bugs previous versions ON.

For getting latest updates, we do the following:

• go to Settings;
• find the item About device and go to the tab of the same name;
• alternately click Software Update and Update.

If there are no updates, proceed to the next instruction.

Useful advice! It is better to download software updates when connected to Wi-Fi or 3G - the speed of normal mobile internet still leaves a lot to be desired.

Reason four - problems with the software part

If the above tips did not solve the problem, the last thing the user can try to do on their own is. The procedure will get rid of the existing errors in operating system... The easiest reset option is with a key combination.

We hold down the volume up and power buttons, as well as the Home key. We hold them until the Samsung logo appears on the smartphone display.

Important! Resetting will delete the information from the phone memory. Pre-do backup important data.

If none of the above instructions helped to get rid of problems with network reception, contact an authorized service center for professional diagnostics and the subsequent implementation of the necessary repair and restoration measures by a qualified technician.

- undoubtedly one of best smartphones that has ever seen the light. But even its owners are not insured against minor problems. However, you don't have to scour a dozen forums to find out how to fix them. We've already done it for you.

For convenience, the manual is divided into three parts. The first focuses on audio and input issues.

1. Sound cracks or distorts

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

2. No alarm sound

In most cases, this is due to a third-party alarm clock incompatible with the Galaxy S7. Try to change it or use standard application... But if the problem is general, then:

• Reboot your smartphone;
• Check before bed for availability open applications especially games or multimedia;
• Take a look at the sound settings and adjust the volume;
• Check the Do Not Disturb status. If you need it, add the alarm to the exceptions;
• Your alarm may have been optimized. If so, find out in Settings> Battery, where you need to select Details in the App power saving section. There you can also expose applications for exclusion;
• If you've recently played, then this may be due to the Game Tools. Their red icon pops up when you start any game, and one of the first options is to turn off alarms during it. You can assess the situation in the Settings> Advanced features> Games> Game Tools section.

3. The smartphone shows a black screen, not responding to keys

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

In this case, the sound and key illumination work as usual. This is usually a job for the service, but try these options first:

• Reboot your smartphone. To do this, hold down the power and volume keys for 10 seconds. Users note that this is a temporary measure and the problem comes back later;
• Another reboot method is to hold down Power, Volume and Home. This will take you to the recovery menu. Use the volume keys to get to Reboot system now, then press the power key to select;
• In cases where the key illumination does not work either, put the smartphone on charge. This usually means that your batteries are simply dead.

4. The power and volume keys do not work

A number of Galaxy S7 owners have noticed that the power and volume keys become unresponsive. And if this is your case, then:

• Seven troubles - one Reset. Try restarting your smartphone. Desirable by simultaneously pressing the power and volume keys;
• If the keys do not respond even to an attempt to restart, it may be due to one of the third party applications... If you guess which one, just delete it. If not, reset your smartphone to factory settings;
• Check for updates for your smartphone.

5. Disable autocorrection

If you don't like auto-correct when you type, go to Settings> Language and input> Samsung keyboard with the Smart typing option, where you need to disable Auto replace.

That's all for today. Problems with the camera, battery and Wi-Fi will be covered in detail in the second part.
