Touch screen is not responding properly

I have a similar problem, but my Iphone six plus randomly types characters in the search box or just opens and closes apps without touching it at all. Other times screen locks. Have tried hard reboot, reset and factory reset.

Currently running IOS11.03

Any clues?

Bring it to the apple store and ask them what is the problem.

If you have tried power off/on, reset by holding the power and home buttons until the apple logo appears and it restarts, and still get this behavior, the only viable solution is an Apple store. There are no virus that infect the iPhone and cause this behavior.

And the screen is not pressure sensitive, it depends on a change in the capacitance of the screen due to contact with the skin...so hard taping and hard pressure have no effect.

The behavior of trying to close apps makes it sound like there is a fault in the screen or its connecting circuitry.

None of which really helps your situation if you are not able to visit an Apple store.

The screen protector folks claim they do not interfere with the functionality of the screen. But now with that piece of info, can you easily remove the screen and try without it in place, or does that create additional problems?

A thick screen may work with some people and not others, or even work for a while and not work on occasion. Depends on the individual's skin, moisture, and other factors. If you can try without the screen protector and it works fine, then you have the solution.

If it makes no difference, then it is probably a hardware problem and needs the care of the geniuses.

Maybe the screen and cover got a little loose? Little gap? Traveling maybe your body chemistry changed just enough to change the concudtivity of your skin? These things are relatively sensitive so could be a myriad of things that all stacked up at the same time.

If it is working fine now, at least you knwo a solution and that is the important thing.

Safe travels.

I just use a simple silicon thing, made by Griffin...may not be what you really want. There are so many when you are in an airport with time to kill, or back home see what they have at the Apple store. Here you can find kiosks in shopping malls that have all kinds also.

Based on this experience, it might be good to avoid ones with built in screen protectors or covers.

I don't think it is your case. I am having the same issue. It isn't consistent at all and is very frustrating. I noticed it today when my phone was charging, but I don't remember if it was charging when I have experienced this in the past week. It just started for me a week or so ago. Was yours charging at the time?

I did some testing and noticed that mine only acts that way when I am charging it. However, it only does it when I am using the very cheap aftermarket charger I bought to replace my lost Apple charger. It doesn't happen when I use my wife's original charger or my (seemingly) better quality aftermarket charger. I figure there has to be something weird in the voltage it supplies to my phone. Time to toss it in the garbage.

May not be your situation, but I figured I would toss it out for others to try if they find this thread due to the same issue.
