IOS 9.2.1 broke the accuracy of touch screen

after my upgrade to 9.2.1, the touch screen accuracy makes the phone almost useless. I can't type accurately, and can't even open the apps i want without opening other apps.

when i lock the screen then unlock it seems to fix the touch screen accuracy for around 10 seconds which then it will go back to inaccurate touch screen.

another issue i've noticed is 2 white vertical lines that shows up in the home screen randomly, but when i lock screen it's not there... so I'm glad it's not HW issue.

this started all from last night after upgrade to IOS 9.2.1

anyone have any solutions on this?

Reboot. Restore. Restore as new.

Those are typical troubleshooting steps. I have no issues with touch screen accuracy, nor does anyone I know.

Your description of the 'white lines', would seem to indicate either corruption of iOS, in which case a restore should solve the problem, or a failing display.

ok, isolated the issue. looks like i have to bring it in. the random disappearing vertical lines across the screen seems to be HW issue, this is also the location that my touch screen doesn't work.

it has nothing to do with the new update.

I am having the same issue. Ever since I upgraded to 9.2.1, my touch screen is useless. It continues to freeze up and the only way for me to temporarily "fix" it would be to lock screen and unlock. It resolves the issue briefly before freezing again.

I have the exact same issue after upgrading to 9.2.1!! It started right after upgrading. I have an iPhone 5C.

Lock screen fixes it for a few seconds.

I've closed all apps and done a hard reset by holding home and start button until the phone restarts.

I have tried factory reseting the phone from the phone's menu.

I have just now also tried a factory reset via iTunes. Still no luck.

I suggest you guys bring it back to apple store. they had to replace the phone... it is more than just display issue. I didn't get the full story.

unfortunately i had to pay.

Thanks for that video rhv12, great that you managed to solve the issues on yours.

My phone hasn't had any screen replacement or any other reparation done and I don't get an error 53 when restoring. But I still have the strange touch behavior.

But I have nothing to lose by trying your method. I'm comfortable opening up my phone, I already did to see if I could fix the problem. I opened it and disconnected the screen cables and made sure they were clean and put them back. Phone works just as before. I'll report back if it helped or not.

The 9.3 update seems to have fixed this issue on my 5C. So it was a software bug after all...

So far so good at least. It's been working correctly for a full day now.
