5. If the mobile phone is really inexplicably hot, then well, the best way is to take it to the store to repair it or change it directly...

Hello, there is a problem with the system, flash the machine and try it, thank you.

When the temperature exceeds the set value, the CPU will automatically downclock, which is to avoid the temperature from continuing to rise, and the CPU may feel stuck when the temperature is reduced.

This is also the case when the computer temperature is too high, and the fan can only be reduced if the phone has no fan.

Isn't millet born for fever? . . It's going to have a fever.、、Bear with it.。。。
