Hi. Only to add to the problem.
Bought an AT&T Unlocked version on Amazon.com on June 2017. Loved the (now) cheap device with premium features.
Few weeks later the whole touch screen started to stop working from time to time. Oddly, I would need to boot holding power button once, back to pattern login to complete boot twice. First time touch wouldn't work. Then boot again holding power button and it would work perfectly.
That was happening in a strange way: Like for one full day having to boot twice each 50 minutes or so. Then working ok for days.
Today I had the problem, but it wouldn't work again, even booting 30+ times.
I followed the steps described here -
https://forum.xda-developers.com/sho...76&postcount=2 - to get rid of ALL AT&T TRASH LIKE DIRECTV AND AT&T MAPS -(WTF? Why do these operators thing they know something? They only destroy devices they touch) and it didn't work.
Everything works but the touch screen.
Everything is perfect, device looks like brand new, but no touch screen.
I was wondering if that could be a small capacitor/ resistor, but in this electronics level it's hard to know.
What seemed like a software problem now converted in apparently a hardware problem.
Shame so many people have this problem.
I will not buy a Blackberry again due to this problem.
Anybody with a similar problem?
