My screens been broken forwhile maybe 6 months started out as cracked glass then black mass blocking upper portion of the screen and moving across display. Then evolved into flashing white and green when brightness wasn’t high enough, then solid green. Smacking the phone or squeezing usually got it working again. Pinching device around the earpiece while turning screen on usually got it displaying an image on the still visible part of the display. Now the whole display was useable still. I was able to press apps that weren’t visible and type basically function of phone wasn’t hindered just the display was damaged. Well last week the phone said enough was enough and stopped wanting to kick the screen on so I took it to get replaced 12/23. Got it back Tuesday 12/28 phone was dead so I charged it on my way back to work and when it turned on the display was responding to touches fine for about 5 min then just became unresponsive. I have to do the force shut down and restart to gain access to the phone again so I took it back explained what was happening and the shop said they would replace it with another display they had. Now I know it’s a different display as I had taken off the plastic screen protector before I took it back and there were a lot of air bubbles under it. Upon receiving it back after them replacing it phone is still doing the same thing and becoming unresponsive after a few min of being on. I have so far tried updating the device and restoring in dfu mode and nothing seems to be working. I know my device is in good shape is this just the unlucky luck of the draw and I got 2 defective screens? Face ID works as does True Tone so it appears to be an oem screen. I am also local to silicon valley so I would hope it is an oem screen. Any ideas I’m thinking of going back and getting my money back tomorrow and getting my old display and finding another shop to repair it
I had a similar issue with a phone that had a broken screen. After replacement touch would stop responding after around 2 minutes and the only way to fix it was with a hard reset. Even at my shop we did have something like this happen once or twice with customer phones, but replacing the faulty screen fixed the issue. I wouldn’t want to immediately place blame on the shop you went to, but the fact that they didn’t really wait and check for touch after you come back is somewhat of a shame. I’d ask for your money back and try elsewhere, because if it really is just a faulty screen I’d question where they are sourcing their parts from after getting possibly two faulty screens in a row. There is the chance you were just luckily unlucky and have a phone with a touch IC issue, but I wouldn’t think that it would be so intermittent and would likely just fail from the jump. Good luck!
