Figured I'd create a post since I saw some blogs talking about a 5A 5G issue with a black screen.
My partners device was misbehaving and at first we thought it was a battery issue, but eventually we discovered that the screen was just disconnecting or turning off because the underlying phone itself was still receiving notifications that we couldn't respond to you or interact with because the screens touch capacity was also not working.
I ordered a replacement screen from iFixit and did the Full Repair assuming that this would resolve the issue, but it did not. Same issue as before, just with a different screen.
Does anyone have any more insight into what's going on here? I've seen some reports that indicate this is some widespread issue, but it doesn't describe what the actual issue is and whether it is with the screen itself or with something on the motherboard or some other component. Any advice or insights or links appreciated.
