Erratic touchscreen after iOS 7.04 upgrade on iPhone 5
I had no problems with the touchscreen prior to upgrading to iOS 7.0.4 in December.
The next day I started having problems with the touchscreen.
At first it only acted erratic when my finger got near the screen, even before I actually touched it. Whatever was on the screen would jitter and not respond properly to what I was trying to do.
I found that just pressing the lock button would fix it, at least for a while.
Now, locking the phone only corrects the problem some of the time.
Also, it sometimes now gets "possessed" and will open apps, zoom in & out, or even make phone calls if the phone app is open. Even if I'm not holding the phone or near it in any way.
Sometimes I can be actively using the phone for more than an hour with no problems. Sometimes it comes and goes for a while.
It has never gotten wet. It's only been dropped a couple times, but always in a protective case and not more than 2 feet off the floor.
The screen is not cracked, and I have never opened the phone. And it was not jail broken.
I have reset the phone multiple times, with and without a backup, and the problem is still there.
My phone is past the Apple 1 year warranty.
Es esta una buena pregunta?
