When the light is flickering at a frequency of 50 or 60 Hz, it will interfere with your photography and video recording, resulting in flickering or ripples appearing on the screen.

This issue is automatically alleviated or eliminated by your phone in general cases. However, if there are multiple sources of light, with variations in their flickering frequency, this issue becomes unavoidable.

If the issue occurs under natural lighting conditions, back up your data and take your device and proof of purchase to an authorized Huawei Customer Service Center for assistance.
