entranceS7 edge problems with mobile internet. Galaxy S7 losing network? There is an exit! Samsung Galaxy S7 volume and power buttons not working
The other day one of my friends was faced with the fact that his newcomer Samsung phone Galaxy J5 loses network after several hours of inactivity. For example, after lying down the night before the device has no network. Only a reboot helps, and then not for long, the edge - until the next night. The phone was handed over to the service for testing and, after a couple of weeks, returned as fully functional. I rummaged on the Internet and came across one similar case where the Samsung Galaxy S7 loses the network in about the same conditions. Thanks to him, we managed to find a solution to the problem! And now I will share it with you.
As it turned out, the LTE / 4G standard is to blame for everything. Or rather, not even so much he as the base stations of the telecom operator. In our case, it was Beeline. For some reason, probably only led by the manufacturer, the phone Samsung Galaxy loses network if 4G / LTE mode is active. One has only to turn it off, leaving only 3G - the problem disappears and the message "No network" no longer appears, everything works like a clock.
How to turn off 4G Internet on Samsung
Perhaps later, with the release new firmware, the problem will be solved, but for now we have to look for such workarounds. So, to turn off 4G Internet on Samsung Galaxy, you need to go to the phone settings and select the section " Mobile networks»:
By default, all are active there. available modes- LTE (aka 4G), 3G and 2G. If your Samsung Galaxy loses the network - try to put the option 3G / 2G:
After that, restart your phone and check. In our case, it helped and the problem went away.
Note: If the high-speed 4G standard is vitally necessary for you, then you should think about changing the telecom operator. Moreover, now it is possible to do this while maintaining the number.
The Samsung Galaxy S7 Edge is without a doubt one of the most best smartphones today, therefore, it is all the more frustrating when it stops working properly. If your S7 Edge is ready to bring you to a white heat, then our guide on the most common problems associated with this device, as well as their solutions, will help keep your psyche healthy and the smartphone itself intact.
Problem 1: randomly turning on the display
You may have the “Simple Screen On” option enabled, which activates the screen when you swipe your hand over it. You need to check this by going to Settings> Accessibility> Abilities and Interactions.
Problem 2: camera crash
Let's dare to assume that your Samsung Galaxy S7 Edge is actually not as hot as a blast furnace - the “Camera Failure” message appears, as a rule, if the temperature inside the device rises. Often this problem can be solved by running hard reset... If that doesn't work, you might want to clear the data cache of the camera app. To do this, in the settings, open the subsection "Applications", then "Application Manager". Next, find "Camera", open this item, and find "Forced stop" in it. After that, clear the application cache and data cache.
Problem 3: wireless charging is slow
Remove your smartphone from the case if it is in it: this case can be the reason for poor wireless charging performance. If that doesn't fix the problem, then check that the Wireless Fast Charging option is actually enabled, and also check that the charging mat actually supports Fast Wireless Charging. wireless charging.
Problem 4: Detect Palm does not work
The Palm Detection function allows the display to ignore accidental presses on it, although in some cases it crashes: even a light touch or simple holding of the smartphone in a certain position can be interpreted by the device as a tap on the screen. In our opinion, such a problem is caused by software glitch and the best solution would be to fit your Samsung Galaxy S7 Edge into a case. You can also stick on the display protective film, although many Edge owners have found that curved edges of the screen make it difficult to fully adhere such a film.
Problem 5: hardware keys don't work
Many owners of the smartphone in question report problems with hardware buttons, however, in our opinion, in this case, the problem belongs to the area software, since the solution to this problem is with the use of hardware keys, but they do not help. If you press and hold down the "On" buttons at the same time and Home, you will perform a hard reset that will help your physical keys work as they should again.
Problem 6: Wi-Fi not working or Bluetooth issues
As a rule, any smartphone may experience certain problems, and in the case of Wifi wireless the router is most often the culprit. Restarting it and rebooting the device eliminates up to 99 percent of Wi-Fi problems, however, if you have connection problems, you need to try again to reconnect to Wi-Fi networks... If you are having problems with Bluetooth, then you should remove any paired devices and then do the pairing procedure again.
Problem 7: Briefing slows down the system
A Briefing app that can create something like an electronic newspaper for you has the same effect on the performance of your smartphone as the size of a fat person can affect your ability to sprint. Make one long press on an empty space of the display, then call Briefing with a swipe and turn it off to improve system performance.
Problem 8: battery draining quickly
An app is often the culprit for a sudden, catastrophic battery drain, so you should close all apps or restart your device to see if the situation improves. Use the notification panel to disable any features you don't need. Also use the Background Data item from the Data Usage section to stop applications that are using your internet channel and plus, turn off the screen.
Problem 9: excessive heating of the device
If your Samsung Galaxy S7 Edge gets hot like an oven during operation, there are a number of steps you need to follow. If this happens when charging the device, then try not to use it at this time, and also disable the item " Fast charging via cable ”in the“ Battery ”section. This will increase the charging time, however, if it eliminates the excessive heating of your smartphone, then such a sacrifice will be justified.
In addition, you will need to check applications for the "wrong" application. Navigate to Settings> Battery> Battery Usage> Advanced and open Optimize Battery Usage. Here you can select the "All Apps" option to make sure that no application runs out of battery while running in the 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: resist the temptation to use super-cheap chargers from little-known manufacturers and cables, including from eBay, as there are already many known cases when they caused excessive overheating, and sometimes fires. If nothing helps to eliminate the high temperature inside the device, all that remains is a factory reset - this is last way before carrying your S7 Edge in service center for repair.

If you cannot perform the cleaning in this way, you need to try installing CCleaner for Android, however, with a full memory, this will be problematic.
Factory reset
Often the problem lies in the insufficient holding of the power button in time, so it must be held until the screen turns on. If this does not happen, you need to rollback through Recovery:
- Press and hold the volume control up and the Bixby key for a few seconds, then power until the inscription appears on the screen.
- In the window, we move down the menu to "Wipe cache", and to confirm we use the power button.
- When the procedure is completed, the display will show “Cache wipe complete”.
- We reboot by selecting "Reboot System now".

- When all the firmware files are selected and transferred, click on Start.
- The procedure takes no more than 10 minutes, after which the reboot window will appear on the display. You need to click on OK and restart the OS.
If the problem is not solved by updating the system, it is recommended to contact the service.
We carry Samsung Galaxy to the service center
The best option is to contact a specialist to repair the equipment. It is advisable to visit an authorized service center, the address of which can be found on the official website Samsung... If after that the screen does not turn on and even a professional flashing did not help, you will have to purchase a new device.
Conclusion

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 Mobile networks item there;
- 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 quality of network reception of different operators mobile communications 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.
To receive 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.
Helpful advice! It is better to download software updates when connected to Wi-Fi or 3G - the speed of regular mobile Internet still leaves much 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.
