I had got the LCD screen replaced a couple of months back after the screen broke from a fall. It worked fine until I upgraded to ios 11.3.1. last week. Immediately after the upgrade the screen started acting up - would respond for 5 mins and then go completely unreponsive. After 20-30mins, again would respond to touch for a few mins and then nothing. I to reset to factory setting using itunes, restored from a backup in itunes. And after that now it is completely non-responsive. I see the screen but can’t interact at all with touch. Took it to the same repair shop, they tried to put a new lcd touch screen but said even a new one is not working. No idea what else could be wrong? Any help/suggestions would be appreciated! Thanks
It sounds like the touch ic is what’s wrong. It’s a motherboard repair so I wouldnt say it’s worth fixing. Its very common with iPhone 6Plus. They have something called a touch disease. And apple knows about.
