Some other users also received this message, although it did not appear after about an hour after taking the device out of the water, and the phone charged without any problems.

Note that, despite the fact that the Galaxy S7 and Galaxy S7 Edge are IP68-rated, the charging port of these smartphones is not covered, and water can penetrate into it.

What to do if the device freezes when turned on

If the Samsung Galaxy s7 edge does not turn on at the initial boot stage and the company logo "freezes" on the screen, this indicates a malfunction of the OS. Here you need to perform a factory reset using any of the following methods:

Across standard settings if Android can be loaded.
By using special programs(there are versions for PC and smartphones).
By pressing hot keys.
By entering a combination of numbers.

Hard Reset by Keys

If after switching on the screen on the Samsung Galaxy S7 lights up and the blue light is on, but the OS itself is not loaded, you can reboot by pressing the hot keys:

We carry out the simultaneous pressing of the power buttons, volume up and menu.
When a dark window appears, use the volume buttons to go down to the "hard reset" option and perform a reset.

Checking the charging capability

When the device does not respond to switching on after charging, this may indicate a loose contact or a malfunction of the charger. To check it, it is enough to perform any of the actions:

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.
Inspect the battery for "swelling", if there is swelling, this is an unambiguous replacement of the part.
Diagnose the battery. Here you will need another device to which the battery will fit. If the second device does not turn on after manipulations, this indicates its malfunction. You will need to purchase a new battery.

How the reset itself is performed through the standard settings:

We go to the menu, select “ General settings", Then -" Reset ".
We are waiting for the phone to perform the operation and reboot.

Clearing the cache

We go to the application manager, select a specific program.
Click on "Memory", then - on "Clear cache".
A large window appears where you can see the progress of the task.

If you cannot perform the cleaning in this way, you need to try installing CCleaner for Android, however, with full memory, this will be problematic.

Factory reset

Press and hold the volume control up and the Bixby key for a few seconds, then power until the inscriptions appear on the screen.
In the window, move down the menu to "Wipe cache", and to confirm, use the power button.
When the procedure is complete, the display will show “Cache wipe complete”.
We reboot by selecting "Reboot System now".

We install the program, connect the smartphone to the PC via a cord, and install the driver.
Launch Odin, look to the left top corner to check if the machine is connected.
We transfer the firmware files to the program, insert it into the AP or PDA field.
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.

If your phone's battery isn't charging properly, don't assume that the only problem is the battery or charging. Based on personal experience, the problem and the solution can be much easier than you think. If your smartphone or tablet is charging poorly or not charging at all, then check out 10 ways to fix these problems.

Why the device won't charge

Problems arise to varying degrees. Either the phone doesn't want to charge at all when it's plugged in, or the process is too slow. Here are some solutions.

1. Bad contact

Very often, the metal coating inside the USB port and micro USB has poor contact, either through a manufacturing defect or through cable wear.

All you have to do is turn off the device, remove the battery if possible, and clean the contacts inside with something like a needle or toothpick. Do this very carefully and carefully, then insert the battery and reconnect the charger. 9 times out of 10, that's all you need to do.

2. Clean the charging port from dust and third-party fibers

Do you keep your phone in your jeans pocket? If so, then fibers may be the culprit: we have already lost count of how many times the fibers in our clothes were the cause of faulty charging.

You can also normalize the charging connector by blowing out compressed air.

3. Try a different cable

The most fragile part of the charger is the cable. He is constantly bending, which can damage him over time.

The easiest way to diagnose a damaged cable is to take another one and see if it works properly with your device. If so, you know the original charger wire is faulty. If not, then you need to look for a solution further.

4. Use a different adapter

You have ruled out the presence of problems with the cable, then you need to check the performance of the charging device itself. This is much easier if you can pull the wire out of the adapter. We have come across many chargers where USB ports have become worn out due to endless cable plugging and unplugging.

Also check the charging / wire operation on other phones, as this will help rule out the possibility that this is a problem with your smartphone. In addition, you must make sure that the outlet is working properly.

5. Remember - safety comes first

Do not charge your gadget near water or in extremely hot or humid conditions. Do not keep the device connected to the charger for too long. Do not leave it to recharge overnight when it only needs 2-3 hours. This could damage the hardware.

If you want to replace the charger or the wire to it, be careful: cheap third-party adapters are quite dangerous. Recently, there have been many cases of mobile phone fires due to them.

The video below captured one of these cases:

6. Replace the battery

Life battery does not last forever and after several years of use it loses its capacity. The more often you charge and discharge it, the more likely it will deteriorate. Of course, if the battery stops working after six months of use, then you need to contact the seller for a warranty.

Some defective batteries can be easily identified by appearance... If it is swollen, then it should be replaced immediately.

7. Charge from the correct source

Charging from a wall outlet will always be faster than from a computer, because its USB ports have too little power. Thus, the phone charges much faster from the socket.

Also, the problem may be that you are using an adapter from another device, for example, from a Bluetooth headset, which is not intended for your gadget. This adapter does not supply enough current. When latest models high-end smartphones, you may have a device that supports fast charging but the adapter is not suitable.

8. Update the software or roll back to the previous version

Updates software may impair battery life mobile phone, especially when the old device receives a fresh Android version... Newer smartphones and tablets are often optimized to take advantage of latest version ON.

If this happened to you and you cannot find a solution, try rolling back to previous version... You can, of course, first try to do full reset as the manufacturers recommend, so as not to compromise the data on the device due to old version Android.

Likewise, sometimes autonomous work smartphone can be significantly improved with the latest update.

9. Try turning it off

Using heavy applications while charging will affect the duration of the charging process. For example, if you are chatting on Skype or playing games, the device will take longer to charge.

Therefore, put the device on charging in the off state or in airplane mode.

10. Calibrate the battery

Sometimes, the battery charge level displayed on the screen may differ from the actual one. Because of this, the behavior of the phone may seem strange to you.
