Dear Samsung users, Hello!

Depending on the situation you described, it is recommended that you try the following:

1.Charge with a cable charge for a while and try to turn it on, or replace a phone battery of the same model.

2.Take out the SIM card and SD card at the same time and try to power on again.

Click Enter and enter your product model and region to view.

I hope the above is helpful to you and I wish you a happy life!

When installing the battery, use a piece of paper to see if it can be solved, if it is not the original battery, it may be a little smaller.

When the phone is vibrate, it will automatically turn off.

Mine has happened to me two or three times!! After taking out the phone buttons, the screen does not light up, and I know that it has been turned off for no reason after the switch! If you don't take out your mobile phone often, it may delay others from contacting you!

This can be big or small, Samsung should find out the cause and solve the problem!!

It is also possible that the battery is not original, and the high-imitation one also lacks an NFC antenna, which may not be tight, and can be padded with paper to prevent the battery from shifting when the phone is shaking! This possibility is not ruled out, although the possibility is very small, it is estimated that there is a quality problem or a system vulnerability!

Mine also has to reinstall the battery before it can be turned on.

Maybe it's the battery that has poor contact.

I've just had this situation too, and it doesn't work to press the power button! Disassemble the battery, reinstall it before you can turn it on...

Why do Samsung phones sometimes turn off.

Hello myself summed up a few points. 1) If the phone is clearly fully charged, it will display 100%, but if you open an app at will, it will automatically shut down instantly. There's a good chance the battery is broken.

That's how I am, the battery can't be charged, and the electricity rushed into it is also empty. 2) The phone's system is corrupted.

3) There is also a possibility that the SD card of the mobile phone is loose, which may cause it to fail to load and shut down, but the probability of shutdown is relatively low due to this reason.

Hello, thanks for supporting Samsung phone products.

We are very sorry for the inconvenience caused by the use of the phone. If your mobile phone often shuts down automatically, please check whether it is caused by the following actions:

1. The mobile phone has newly installed third-party software (caused by the compatibility between the software and the mobile phone) 2. Whether it has flashed the phone by itself.

3. Check the phone battery problem.

4. Back up your phone's data (**book, information, multi** files, etc.) and restore your phone to the original factory settings (Settings - Privacy - Restore Factory Settings).

If the above methods still can't solve the problem, it is recommended to send the phone to the nearest Samsung service center, please click for specific service center inquiries.

Hope the above information can help you, thank you!

Do you have an automatic shutdown, or is it the default? If you look for it, you might be able to find the reason.

How did you solve your problem, mine also automatically shut down, and it was like this in less than half a year after I bought it.

It's also power-efficient with airplane mode!! I'm going to use this now, it's very useful!!

Click the alarm clock, and then press the button on the left side of the home button, turn on the alarm clock before there is an alarm, click it, go in and tick it.

Then you have to set the alarm clock, and then set the alarm clock to turn on before the alarm clock, it seems that the alarm clock will automatically turn on three minutes before the alarm clock. I've tried, and it works. As for the automatic shutdown, I don't know.

Mine is the same way, I don't know how.

It seems that we all have the same problem, find more settings in the settings There is an automatic power switch in it, dear, does it still help you? I hope I can help more friends who use this mobile phone

This phone does not support automatic power on and off alarms.
