What if the screen of Glory x20 turns black and white?

If the honor screen turns black and white, the following methods are recommended for troubleshooting:

First, check whether the sleep time/stop time for healthy use of the mobile phone is turned on.

If the sleep time/stop time for healthy use of the mobile phone is set, the icons of unavailable applications will turn gray after reaching the limit time.

Turn it off: Go to Settings > Healthy Use of Mobile Phone > Sleep Time/Stop Time, and check whether the switch is turned on. When this setting is turned on, the screen will turn black and white when the phone reaches the set sleep time/stop time.

Second, if the above troubleshooting can't solve the problem, try to restore all the settings of the mobile phone.

This operation mainly restores network settings, screen lock password, desktop layout, etc. If the mobile phone supports fingerprints or faces, the fingerprint and face information will also be recovered, and other types of data or files will not be deleted. Find devices, users and accounts, device manager, application settings, etc. Will not be restored.

Go to Settings > System and Update > Reset, click Restore All Settings, and restore according to the on-screen prompts.

Third, if the problem still exists, it is recommended to go to the service center for testing and handling.

Find the preset application of HONOR- My Glory App, open it, enter the service page, and click Quick Service > Go to Store Service/Service Store to inquire about the nearby Glory Authorized Service Center. It is recommended that you back up the materials in advance (such as QQ, WeChat and other third-party applications separately), bring the purchase voucher and call Glory Authorized Service Center to confirm the time in advance, so as not to delay your time ~
