Chosen Solution
Hi, as the title says: The replaced Display on a iphone 5S flickers only after a call. Does anybody know why? Thanks Update (22.04.2018) I fixed the problem. A few days ago, i changed the battery on the same phone for a customer and the screen again. I dis- and reassembled the „lightning-connector“ for changing the battery. Summary: Changing the Battery and check the lightning connector seems to solve this problem.
There could be a few different reasons for this but the first thing to try is to verify your connections on the replacement screen and if that looks okay, then try a known-good screen assembly. Depending on where you bought your display and how much you paid for it, it could be a low-quality or partially defective replacement screen.
