Because there is not enough memory in the phone, the camera can't start and the video can't be used. Operation example:

1. First of all, you need to open the page of your mobile phone, and click the mobile phone housekeeper icon on the page to enter.

2. Then clean up the accelerated scanning directly after entering, and the mobile phone is slimmed down to save memory.

3. After the final selection, press and hold the phone power button to restart the phone, and then turn on the recording, so that the operation can solve the problem.
