What about the black screen of the mobile phone?

If you are using a Huawei mobile phone and the camera cannot be turned on, please follow the following steps:

1. Clear camera data

Open the settings, search into the application management, and find the camera >; Click Save, and then delete the data to try. (This operation only restores the relevant settings of the camera).

2. Restart the device

Some applications did not release the camera normally after use, which caused the system camera to fail to start normally. Please restart the device, then enter the camera and try again.

3. Check the updated system version

Please back up important data in advance (QQ, WeChat and other third-party applications need to be backed up separately) and upgrade to the latest system version. Updating the system version is beneficial to improve and optimize the performance of the camera.

Please enter the third-party application such as WeChat /QQ to confirm whether the camera can be turned on normally. If it can't be turned on, it may be a camera hardware problem. Please back up the data (QQ, WeChat and other third-party applications need to be backed up separately) and bring the purchase voucher to Huawei customer service center for testing.
