Q: Has anyone lost the sensitivity on the touchscreen after iOS 7 upgrade?

I've had my iphone 4S for just over a year now.  It has worked flawlessly right up until today.  Just upgraded to iOS 7 about a week and a half ago.  Today, the touch screen stopped responding.  I could pull down the notification and sometimes pull up the utilities but anything in between on the screen would not respond.  Could not unlock.  Holding sleep/wake+home button for 10 seconds (as recommended by Apple) seemed to work.  But seems more than coincidental that I have had absolutely zero functionality issues until mere days after iOS 7 upgrade.

Note to Apple programmers: I had just used the camera without unlocking prior to the touchscreen not responding.  That was the last thing prior to it's failure.  Would not unlock after that.

Ahhh! I have the same issue.. It's quite frustrating.  After upgrading as well, soon after the left side of my screen is unresponsive.  I have tried everything from the link  Allen A ^ has provided numerous times and still nothing. I even tried a reset which right after worked fine again until a minute later and it went unresponsive again. I have to flip back and forth to type and other things.  I have a mini also. Never dropped, never wet, never near any magnetic source either.. It was given to me as a gift so it's not like I have warranty coverage. So hopefully someone could figure out this issue soon. Please Lmk if anyone figures out anything. Greatly appreciative.

Maybe Apple could fix this issue in the next general update..  Don't you think?

I have a similar problem is yours fixed? How?

Hi is your problem fixed? It seems we exactly have the same problem.. It one inch at the left side (ipad standing)

This looks to me to be a software, not a hardware problem.  When I upgraded my iPad 2 to iOS 8.4 from 5.1.1, I noticed not a lack of sensitivity, but the fact that it's not always paying attention to touch.  Probably the worst offender is when trying to delete an app icon.  It is very unresponsive to clicking the X.  Other touch actions in other contexts work fine, it's just certain things don't work very well.   It's a shame, because the main thing I thought Apple tablets had over Android was their smooth touch interface.  Now it's having some of the same issues I've seen with Android systems.  I suspect they re-did the main touch driver and because of it will sometimes lose inputs.  I've also seen some evidence that they capture touch inputs in an input queue and sometimes the rest of the OS is to busy to process them and they back up.   And then sometimes you'll get them all at once, I clicked a bunch of times in succession to do a delete when it wasn't responding, and once it finally started to respond it repainted the screen over and over and over for the number of times I clicked it, to the point I thought it was stuck in a loop but it finally came out of it.   It never used to have that sort of problem pre-6.0, never on my original 5.1.1 iPad, and also not on my iPod Touch that's running 6.1.   With 8.4 though, it's one of the first things I noticed.  It's behaving like it can't keep up and is sluggish in its response to the point of entirely losing input at times.  Whatever they did to the input driver, messed it up.
