Anonymous users2024-02-08Look at what kind of fault the phone is. For example, Nokia's white screen restarts repeatedly after booting, or a certain function can't be entered, etc. This kind of failure can be seen as a software problem just by thinking about it on your toes.
Another example is the MTK series of domestic machines, which constantly prompts the charger to connect and remove the charger, and you can know it with your toes.

Anonymous users2024-02-07Auto power off (auto power off).
1. Automatic shutdown when vibrating.
This is mainly due to poor contact between the battery and the battery contacts.
2. Press the button to turn off.
As long as the mobile phone does not press the keyboard, the mobile phone will not shut down, and the mobile phone will automatically shut down when you press some keys, mainly due to the virtual soldering of the CPU and memory, and strengthening the soldering of the memory CPU and memory can generally solve the problem.
3. Launch and shut down.
The mobile phone will automatically shut down as soon as the transmitter button is pressed, mainly due to the failure of the power amplifier part, which is generally caused by the power supply IC (or power amplifier control).

Anonymous users2024-02-06Phenomenon 1: The mobile phone does not turn on (the mobile phone battery is removable).
Solution: Put the battery on the new mobile phone (or after upgrading, after restoring factory settings) and turn on it for the first time, the mobile phone needs to be initialized, and the boot time will be longer, which may be mistaken for not turning on. For the battery over-discharge caused by not turning on, remove the battery, connect the mobile phone to the charger to see if it can be turned on, if it can be turned on, install the battery and charge it for more than 30 minutes, it can be turned on normally.
Phenomenon 2: When the mobile phone is placed in a pocket and the touch screen is in contact with the body, the incoming call cannot be answered by swiping the touch screen**.
Solution: Keep your hands and touch screen clean and dry, press the power button (lock screen button) twice to let the touch screen recalibrate itself, and then try to unlock it.
