What should I do if the breathing light of Duowei A8 keeps on red and cannot be turned on?

Possible reasons and solutions for not turning on:

1. Battery reasons. Check whether the power is sufficient and whether the battery is deformed or loose. Charge it for more than half an hour and try again (applicable to mobile phones that have not been used for a period of time). Replace the battery

2. Check whether the buttons are malfunctioning

3. Software reasons. For example, if you have flashed an unofficial system or rooted, you can try flashing the official rom

4. Hardware reasons. For example, water, moisture, falls, etc. Send for repair

5. For an all-in-one machine, press and hold the power button for 15 seconds. If it cannot be turned on, charge it for half an hour and try again.
