Has anyone noticed that when you swipe up to close out an app that the screen in the background behind your home screen pic flickers for a brief second. I have no other issues with the screen. Works great and looks great but just noticed that when you close out on an app that it shutters or flickers. It’s really slight and didn’t notice it before probably. Just want to make sure it is not a problem as I am within my return period. Is this normal?
