I just started using this phone a couple of days ago & it's done this twice now. I currently can't use it! I don't want to do a reset as I assume it will delete everything I've transferred onto it, do you know if the reset does that? Thanks. Also had issues with playing music, and taking 2 photos, it overheated and said it couldn't be used until cooled down 😞
I had a similar issue after the recent software update. I was able to hit home and pull down menus though. couldn't tap on the screen proper. Turned off added touch screen sensitivity (used for when you have a screen protector on the surface). That seemed to help but then it glitched out again. Rebooted (cycled the power) and I noticed as soon as my Twilight app turned on my touch screen went dead again. Twilight is a blue light shift and uses a screen overlay. If you have any app that's using a screen overlay that may be it.
