Touchscreen unresponsive from time to time

"Looks like you got a dud touch-screen on your unit. There's nothing you'll be able to do to get it working without voiding the warranty on the unit.

My advice is to take it back to the place of purchase for an instant swap over. Don't let them take it into a 'repair' process, as you are entitled to an instant swap over within the first 10 days from your invoiced date.

Hope this helps"

This tutorial helped me to fix unresponsive screen on my iPhone 6.

"Did you ever get this worked out?

Have you checked to make sure you have at least 10% free storage space on your device? Clear out the multitasker as well. New iOS updates have been known to give legacy devices problems.

Apple says that multitasking doesn't affect performance, I beg to differ. All of my iDevices are Jailbroken and when I clear the Multitask bar, I can watch my available memory jump up.

A dud screen will have consistent dead spots. Usually the same spot in every app and screen. If it is just taking a year(iphone time) to respond (real time is like 60 seconds), then it's most likely software related. Have you restored and setup as a new device? Do not restore from backup as maybe your backup is corrupt. If the problem persists, there might be a bigger problem with your logic board. Doubt it though.

I know it's been a year since you've been here but I came across this looking for links for a customer of mine with the same issue.

Really just posting some info and curious I you got it worked out or just bought a new device."

"my i phone 4s is facing a problem of touch some times .

so i have reseted it .but when touch is not working a;; keys are working

and if i restart it again it is working ."

I had similar touch screen freeze-ups and tried the above fixes without success. To fix it I had to back up my iPhone to my computer via iTunes, then turn off Settings/iCloud/FindMyPhone, then Settings/General/Reset/Erase All Content and Settings. Then during iPhone setup, I chose to Restore from iTunes Backup (or something to that effect). Now it works like new again!

Hello I have an iPhone 4 and it suddenly had a problem the touchscreen doesn't respond in some apps I tried restoring and it does nothing I can slide it to open but when I use some apps like Safari it doesn't resond. Even when I swipe up to open control center it doesn't respond at all I'm running iOS 7.1.2 pls help
