How to use the video recording function of the mobile phone when locking the screen?

You can use the Mi-key, install the Mi-key APP, and make relevant configuration, so that you can record and record quietly in the screen lock state.

If you can't use the video recording function of your phone, it is recommended to follow the following steps:

1. Switch the phone again to see if there is enough storage space.

2. Go to phone settings-Application Manager-All (swipe the screen to the left)-Click on the camera-Clear the data.

3. Back up mobile phone data (phone book, SMS information, multimedia materials, etc.). ) and restore the phone factory settings.

4. If you don't encounter any major failure in the process of using your mobile phone, or this phenomenon appears after some operations, it may be a problem with the settings or a system program error-you can't identify this device. To solve this problem, you can read the instruction manual carefully, or you can restore the factory settings and let the system automatically detect the equipment again.
