What should I do if I quit the phone launcher and won t turn on 40

Generally, the mobile phone cannot be turned on for the following reasons, which can be self-checked.

1) Check whether there is a virus on your phone.

If the phone suddenly and frequently restarts, it is likely that it is a virus. You can use the mobile phone security guard to scan and disinfect the mobile phone first, and clean it up.

2) Uninstall some unnecessary software.

If there are too many mobile phone installers and too many software running at the same time, it is easy to fail to run and restart.

3) Software conflict issues.

If you think about whether you have installed or upgraded any software recently, it is often these software conflicts that cause the system to restart automatically, so you only need to uninstall the software that caused the conflict.

4) Factory reset.

If you can't be sure what software or plug-ins are causing your phone to restart frequently, you can choose to factory reset your phone and save the more important things on your phone before doing so.

5) There is a problem with the SIM card.

In addition to the internal software problems of the phone, the hardware problems of the mobile phone can also cause the phone to restart, and the SIM card error is a common hardware problem. Change a SIM card to the phone and see if there is a reboot to determine whether it is a SIM card problem.
