Why can't Apple VI open SMS when it is turned on? Looks like a car crash.

Smartphones, like computers, crash, restart or fail to boot for many reasons, which can be roughly divided into two categories: software and hardware.

1. There may be some applications in your system that interfere with the normal operation of the system, especially some programs that have obtained root permission. For the safety of the mobile phone system, please do not use root permission at will.

2. It may be because the software is not compatible with the current system version, which is similar to a computer. For example, some programs can be used normally under windows XP, but they can't be used under win7. In this case, you need to wait for the software upgrade.

3. It may be that an individual mistakenly deleted the system file during use, and it can be solved by reinstalling the current full version of the system.

4. Very few machines may be caused by hardware problems, if this happens repeatedly on your mobile phone. You can go to the maintenance point near you to have a test.
