| My HUAWEI phone screen shows only black and/or white colours or looks warm |
If a tempered glass screen protector or non-official screen protector is attached to your phone, the colours on screen may not be accurate. Try removing the screen protector and checking again. In addition, set Huawei Home as the default home screen app (by going to Settings > Apps & services > Default apps > Home app > Huawei Home for HarmonyOS 4.2 and earlier versions) and use an official preset theme.
HarmonyOS NEXT does not support setting the default home screen app. Thank you for your support and understanding.
If the problem persists, perform the following steps:
Scenario 1: The screen shows only black and white colours
Scenario 2: The app background is black
Scenario 3: The screen colour changes from cold white to warm colours
Scenario 4: Home screen icons all turn black
Scenario 1: The screen shows only black and white colours
- Check if Simulate colour space is enabled. If so, go to Settings, search for Simulate colour space, and select Off. (If Simulate colour space is not available, it means that this feature is not enabled. Skip this step.)
- The screen turns black and white when eBook mode is enabled. To disable eBook mode, open Settings, search for and touch eBook mode.
If eBook mode is not available, it means that this feature is not supported on your phone.
HarmonyOS NEXT does not support Simulate colour space and eBook mode. Thank you for your support and understanding.
Scenario 2: The app background is black
If the background of a system app is black, it means that Dark mode has been enabled. To disable Dark mode, go to Settings > Display & brightness > Dark mode.
Scenario 3: The screen colour changes from cold white to warm colours
This occurs when Eye Comfort is enabled. To disable this feature, open Settings, search for and touch Eye Comfort.
Scenario 4: Home screen icons all turn black
This occurs when Colour inversion is enabled. Open Settings, and search for and touch Colour inversion to disable the feature.
