iPhone acts odd, crazy, touch screen, random behavior, while charging

This post only addresses iPhone acting up while charging and using the device.


Problem:

I have a cord and wall charger I take with me in my laptop case. It charges the iPhone fine, but... when I attempt to use the iPhone while it charges on this cord the touch sreen responds CRAZY, or RANDOM, like an invisible finger is pressing another area of the screen.

I can not consistantly or hardly OPEN the device by "slide to unlock" .... most of the time it actually ZOOMs in like the 3 Finger touch.

ONLY when I unplug the phone can I "slide to unlock" and have normal use of phone.


Troubleshooting:

We have 5 Apple devices I tried all the Cords with all wall Plugs...


Solution:

Turns out that we some how have a Wall Plug that doesn' appear to be "Designed by Apple in CA"

All the other plugs either have an Apple Logo or state "Designed by Apple in CA"


...This one that doesn't work properly has the same model #'s and voltage written on the face, but says "Power Adapter made in China"


It Charges fine but, must have a grounding issue or something that causes the touch screen to respond Crazy & Odd.

I Marked this one with a sharpie marrker "X", we just use it to Charge as a last resort.


If you have similar issues this could be your best bet....test it yourself with another cord or wall plug.

iPod touch, Windows XP

I'm getting something similar to what you're describing. I've noticed that when my phone does move on its own, it is as if the screen is being pressed in the same spot repeatedly.


I've switched positions of the icons and the position seemed to be the culprit. Today it was a different position. The new position is at the phone icon in the lower left corner. The icon was selected then the contact in that position was called.


Couple of things to note:

  • First and second occurrence the USB was connected to my laptop. Third occurrence (this morning) phone was connected to a surge protector with the apple adapter and cable.
  • My phone is an iPhone 6 128
  • I have my phone in an Otterbox Defender case, which has a screen protector built in.


Hope this helps.

Hi


did you get amy answer on it?


unfortunately also my Iphone 5 started to have this random behaviour suddenly and independently by any charging


Quite worrying also because the random pattern looks not so random


After doing quite a lot of research on this issue -it happened suddenly just 2 days ago but spent quite lot of time to research and trying to solve it for safety reasons-i see there are not serious answers except a bit generic and more fanatics ones that are really inappropriate when an issue like this is becoming more common


tried to reset, restore, delete software, etc, : nothing happens, still same "random" behaviour


Really worrying, i have five Apple devices all connected and hope it does t spread to all of them


Who could seriously help?


(Going to try Apple genius shop but feeling it ll be just time lost as it happened to read about others with same issue)


With the next iphone 6 launch, shouldn't this issue taken more seriusly?

I tried to find out if it is happening on a charger that is not genuine Apple charger but I cannot tell. The charger for the iPhone 5S looks like a real Apple Charger.


The problem only happens after the phone reaches Full Charge and pulling the cable out stops the spurious keyboard activity


I have looked at YouTube videos showing how to tell if a charger is not genuine but that did not help. I think it is a real UK Apple charger

I have a similar issue:


- iPhone 6 Plus. iOS 8.1.

- original Lightning cable

- connected to Mac book Pro Retina 13, late 2013.


-> when the phone is connected to the mac, the screen registers touches around the area where I am actually touching. Sometimes this only results in quirky scrolling, sometimes the phone is rendered unsuable (can't touch anywhere, or phone registers touches where I didn't).


--> I can pull the cable and the screen is responsive again. Once I connect it, the phone behaves the same. A reboot did not help.


Anyone with similar issues? This sounds like a hardware bug to me.. :/

Best

I've had this on an ipad and I'm 99% sure it's a faulty digitizer.

Sometimes links wouldn't work, sometimes apps would open and do things by themselves.

After some careful observation however, for me it was apps in a line across the middle, and spinning the ipad around I could see it was differnet apps but in the same places on the screen.

Similarly, links that didn't work or letters that seemed to be stuck, spinning it round they would work or it would be different letter.

I replaced the digitizer and fixed the problem. The home button was replaced too so I can't discount that it might have had something to do with it as it felt unresponsive.

I can't possibly say if you have the same thing of course, but that was my experience.

Finally! Others having the same issue as me. When I got my 6 Plus 128 it started doing what you describe. I even managed to do a screen recording via an app on my PC. AT&T exchanged my unit after a senior Apple rep referred me to them (I live in Puerto Rico and there are no Apple stores).

This unit just started to do the same randomly. I did notice, however, that the anomaly occurred while connected to the cable. This makes me conclude the lightning socket may be interferring with the screen or touch sensor/digitizer.

If anyone is interested in the short video I managed to record, let me know. I could email it.

I'm experiencing the same behavior with my iPhone 6 Plus--with an Apple iPhone 5 charger designed in CA and made in China--that I just used with the iPhone 5, an iPad Air II, and my iPhone 6. Once I read this thread and unplugged the charging cable, the erratic behavior stopped. The behavior was such that it seemed that someone else had remote access and control of the device.

Ok this has been happening to me since I first set up the phone, and it happens when its plugged in OR not plugged in, doesnt matter.


It started by always randomly switching apps, mostly opening the appstore. Now it types on its own, switching in and out of text conversations, and deletes text after I type it. I cant do anything without this thing deciding what actions its going to take on its own.


After reading this I move a few apps around on the home screen to see if it was the location of the appstore app, well see but I think I am going to get this thing replaced. So much for QA Apple.

I'm seeing the same thing.


My iPhone 5S is kept in a Mophie charger, which I charge via Micro USB. Hooking it up to my MB Pro Retina 15" and touching the iPhone screen while charging makes the phone go crazy. It's funny to see that when you open a new note, it will start to type random characters and do all sorts of things in the note.


This must be some current flow or something that makes the screen interpret things differently.

This just started happening to my 5S 64. Charging was/is not involved. The descriptions of it being like someone else is using the phone remotely are apt. That's exactly what it's like. I've determined that if I ever-so-slightly "flex" the phone by grabbing it at the ands and twisting (just a tiny amount) I can exacerbate the problem. I have babied this phone. It's never been dropped and spends its days in my breast picket in a BookBook leather case and its nights on my nightstand.


I've done a full backup and restore to no avail.


Weird.
