What to do if the screen flickers or the display is erratic

If your phone flickers or the display is erratic, try the following steps:

1. Restart your phone and re-open the app in which the issue occurred.
2. If the issue still occurs, open a different app and see if the issue persists.
3. If the issue does not occur with other apps, there might be something wrong with that particular app. Try downloading and installing the app from HUAWEI AppGallery. Make sure the app is up to date. If this does not resolve the issue, report it to the app vendor.
4. If the issue occurs in all scenarios, back up your data and take your device and proof of purchase to an authorized Huawei Customer Service Center for assistance.
