Today I bought a iPhone 6 plus and the guy I bought from said it was a touch screen issue since it sometimes doesn’t work, but if you press screen hard, it would work. Of course I knew this is not true. this is what the grey bar of death look like.
Hello, grey bar. It won’t let me setup the phone, touch is not working.
There is detailed discussion on this issue and explanation why this is happening. here : http://ifixit.org/blog/8309/iphone-6-plus-gray-flicker-touch-death/
I have my own opinion though to explain why this can be worse and worse as time pass by and can be fixed by twisting the phone. All of these are not that important but we need to fix the issue in the end of the day.
Bye, grey bar. How did I make it work? I reflew touch IC. Did it work? yes. Will it work for long? No.
That is why this is WIP post. I am currently awaiting on touch IC to arrive and replacing ICs, it will fix the problem.
Ok, chips arrived, lets do it.
Tape it up… safety first!
Heat…Go!
Get ready for solder balls
Shinny shinny balls…
This is called a clean pull. clean pull, and clean pads
Install new touch IC back, problem solved.
