    Welcome to Android Central! Does it also happen in Safe Mode? https://safemodewiki.com/how-to-enab...uawei-p20-pro/

    Hi, welcome to AC!
    If its still happening in safe mode then try factory reset or might be a software glitch

    If it persists after a factory reset, then it could also be a hardware fault with the screen or one of its connections. You'd have to bring it to a repair shop (or contact Huawei, if it's still under warranty).
