How To Fix Google Pixel 7 Screen Flickering Issue 

In most cases, screen flickering issues are caused by app or system-related problems, although there are also times when it’s due to a hardware issue. But as long as your phone doesn’t have any signs of physical or liquid damage, this problem can be fixed. 

After the reset, observe your phone without even setting up your account yet. If the flickering is gone, then continue with the set up. 

However, if the problem is still there, then it’s time to have the device checked by a technician. At this point, it is possible that the problem is with the hardware already.
