No touch, noticed a "glitch" on boot
So I have an iPhone 6 that recently got water damaged, and after replacing the battery and screen I got no touchscreen. The replacement screen is a known good screen (tested on other iphone 6). I was thinking about attempting a touch ic replacement but I noticed that on boot the logo flashes for a second and comes back. Why is this brief glitch happening and is it related to my no touch problem?
Is this a good question?
