1, battery problem.
When the mobile phone is constantly restarted, you should consider whether your mobile phone has been repaired by a physical store, changed the battery, or whether you bought a fake battery online or in a physical store. Inferior batteries may affect the fluency of the motherboard, causing the phone to crash and restart. Therefore, it is best to be around or give a signal to the battery when repairing the mobile phone. When buying batteries, don't buy fake batteries cheaply.
Solution: Replace the battery.
2. the 2.ROM problem.
The second reason may be that the unstable system was brushed and some defective Roms were brushed, which caused the phone to crash and restart. It is suggested to keep the official system. After all, the official system has been tested many times before entering the market, and the stability is definitely very good. In addition, when you brush the machine, you should also inspect it in many ways. If you can't see the system, just brush it. Be sure to consult other friends and friends, and then consider whether to brush the machine after you have a certain understanding of the system.

Solution: Debug related equipment to see if the line is loose.
