Restart the phone. Sometimes, after the phone restarts, the problem may be resolved. Turn off the phone, wait for a while, pull out the board, and put the phone for a while, this time do not charge.
Take out the phone card, and use the official charger for direct charging at this time, about 30S-1 minutes.
Then unplug the direct charge, put the phone board back into the phone, put the phone card back, should be able to charge. If the fault persists, try again several times. If it still can't be solved, it can only be sent to the after-sales service.
