Chosen Solution

Hello every one as phone repair technician I would like any expert to help me with one problem that I am trying to figure it out. My iPhone 6S Plus old screen was giving me problem sometimes flickering I was doing ok with that. Everything was working completely fine. But one day I decided to replace my screen and I did it. So after replacing my screen now the problem that I have is very annoying. Screen freezes and I have to do hard reset every single times that happens. I cleaned all the connector very well but still same problem freezes. But the weird part is that if I put back my old screen the screen works fine but just flickering one and a while. Oh and by the way during night new screens don’t freezes so I am confused. Any opinion? Update (03/19/2017) You’ve made too many edits recently. Wait a little while before you try again.

Hi Alberto, Sounds like the touch IC on your logic board is going bad. Hope this Helps Steve Professional Repair Tech for over 5 years
