Hello i am facing a problem with my iphone 8 .Sometimes when i power it on it creates artifacts on display.and sometimes it goes on a bootloop and after 3 times it opens.i changed the screen and it does the same .Anyone experiencing the same problem ?

That’s a telltale sign of motherboard failure. I suggest take it to the apple store ASAP.

I agree with akash and at best is a loose ribbon cable but likely a damaged component on the motherboard.
