iPhone 13 control center blur icon problem
these are two different iphone 13 of me and my uncle, there is no ghost icon in my uncle's control center, but when I open control center on my phone ghost icons appear in the top right and top left corner, I took it to the authorized apple center service, they replaced the screen with the original screen but the problem persists, hard reset doesn't work, could the problem be with the GPU or what's the problem? can you help
