What should I do if the phone s power button and volume down button fail?

If you have this problem with your phone, you can try pressing the power off button all the time to see if your phone responds.

If there is no response, it means that the phone itself is faulty, you can remove the battery, clean it and reinstall it to see if the problem is solved.

If it still doesn't work, it is recommended to go to the mobile phone repair shop to deal with it, or you can contact the official after-sales service for repair.

Emergency tip: Plug in the charger first to keep the phone charged. (It is best to connect directly on the power supply.) Sometimes, the connection on the computer may fail due to insufficient power. ）

The body of a phone or tablet has a pinhole-sized pinhole (this is a kind of restart button). Rub it in with a thin needle and press that button. Restart your phone or tablet.

Open the settings of your tablet or phone, and set Brightness (Display) to set the maximum standby time. If there is a never-black frequency (always standby), set never.

This will allow you to be able to meet your needs before you don't have time to go to the repair shop for a while.

Usage: The power on button and volume down button are in the power off state, and press and hold the power on button and the side volume button down button at the same time to turn on the phone.

I disassembled the two screws at the bottom and opened the back cover. I saw that the battery was bulging, and the plastic packaging of the battery was bulging, causing the mobile phone to be closed loosely. The switch is out of order.

Take a needle and poke a hole in the plastic, squeeze the air out and glue it with clear glue. Everything is OK after installation!

If you are using a vivo phone, you can check the following troubleshooting methods:

1. Confirm whether to use a third-party 3D tempered film, and confirm whether the glue flows into the gap of the button, when pasting the third-party 3D tempered film, it is recommended to use other pieces of paper to cover the key position before the film to prevent the glue from flowing into the gap;

2. Restart your phone to see if it is restored;

3. After backing up the data, go to the phone settings - system management More settings - backup and reset Restore factory settings - restore all settings to try (this operation will not erase the phone data).
