Touch screen going crazy

I think you may be on to something with your "static" theory. I do have mine plugged into a surge protector (in fact the surge protector has its own USB charging ports, which I use), but the charging cable was lying across my bed, so the potential for a static charge running through the cable is definitely there.

I unplugged and restarted my ipad, AND I cleaned the screen (it had a LOT of fingerprints all over it, and I know from working with electricity that static charges can travel across dirty surfaces very easily). So far, so good. The screen seems to be working fine now.

I have just had this problem with my wife's ipad 2 but only when plugged into our mac mini, randomly the screen started going crazy, opening emails, trying to type them, opening apps etc.. Rebooted and re installed the software on a clean install and the minute i plugged it back into the mini the screen when crazy again. The problem is unique to the ipad and the mini, when i plug the ipad with the same cable into my macbook it behaves normaly, Secondly if i plug in a different ipad to the mini then that ipad also behaves erratically.

Our mac mini is plugged into our tv via a hdmi cable, the hdmi cable and the usb ipad cable are close to each other when plugged in. I noticed that if the hdmi cable is removed the problem seems to stop, if i press the hdmi cable close to the usb cable then the problem seems to get worse and pulled away better. So i believe it's got something to do with interference, it may also be a power supply issue either from the mini or going into the iPad. I also notice that the mini's bluetooth tackpad does not respond well or smoothly when the iPad issue is going on, this is several feet away from the mini. Strangely though the mini has been setup this way for a couple of years and we've never had problems syncing the ipad before, this makes me think it might be a power supply issue, perhaps this is causing the interference. My next step will be to replace our hdmi cable to see if this is the issue.

12) go to settings and switch off Bluetooth. turn off Multitasking gestures. select keyboard and turn off split keyboard. turn off the following too; auto correction, auto capitilisation,check spelling and shortcut.

that's it, ipad should now be problem free.

It seems that for the last few years (read - since they introduced the Lightning charger). It appears that when plugged in for charging purposes, the heat reacts with the touch screen and can cause phantom touches. If your screen is unlocked it can open apps, make text messages (not coherent ones, but it types) and place phone calls. You would think that several years later Apple would have a better answer to this issue. Then again, you would think they would add the Reply vs Reply All feature to text messaging so we can choose who we respond to. But apparently we keep buying the devices so they dont seem to care.

I was having the same issue, I live in an old house with old electricity, I've been using apple chargers and apple blocks to charge my phone and when plugged in I couldn't even type or do anything on my phone after trying a few things I switched the power block with another apple one, always the same, got a few more brands and always the same.. I was about to throw my phone.. But i thought I'd try one that my work gave me, I don't know if it has anything to do with it but there's a little light on it. Works well now. But even though I fixed it, I still want to know the cause so I looked into the electricity in the house, there's a ton of EMI (electro-magnetic interference) and also the voltage here is over 120v usually around 130/135 so I think that little light is using the excess and sending my phone the right current. Just a thought and my non-expert explanation. Maybe someone with more knowledge could point me right or wrong. By the way I made a whole new wiring from the electrical box to my room where i plug my phone with brand new EMI free wire. Still gives 130v but it works that's all that matters to me.

Edit: The power block from apple worked for a week or so on the new wiring. I've been using the one with the little light for about a month now and no issues have shown up and as a bonus it charges way faster in 30 mins or so, 0 to full. When it used to take over an hour.

My problem was my iPad keyboard went bonkers often,

like it had a mind of its own.

I found the solution to be my iPad case the 4 corner

clips were too tight. Removed case and no problems.

Without the case on, I tried typing while applying thumb

pressure on lower corners and keyboard acted up again.

Of course I will not apply pressure anymore and hopefully

live happily ever after. Definitly a manufacturing issue.

Hope this helps.

Hello,

I have exactly the same problem with iPad2. It only appears since I use a new recharger and since the old one is defect. The touch screen only plays crazy as long as I recharge the battery. It is able to unlock the device, to write messages and to paint images and to use other Apps in an uncontrolled way. The problem disappears completely when I remove the battery recharger. I also think that other devices in the close area might play a role here and that there are electromagnetic interferences (EMI) who cause that problem. The attached image shows how the touch screen played crazy while the Notepad+ App was open. The dark blue lines were paint by the iPad (which got an own personality), not by a person. Nobody used the iPad at that time. I didn't have my hands on it, I only looked at it. The screenshot (which was made afterwards) only shall show how the touch screen plays crazy.

It also makes me scared a bit if I think about it. I just hope it hasn't any long-term effects on the device.

Edit: Since I know about that problem, I turn off the iPad while recharging the battery. Or I use the USB slot of my Mac mini to recharge the battery, the problem doesn't appear there. But, beside of that, I think that such problems shouldn't appear. It also shows another time that Apple doesn't stand for quality anymore.

I'm having a similar issue, when I turn on the iPad the screens will go back and forth automatically, it will leave white dots on the screen, it will start typing something random like aaaaaaaqqqqq-1 in the google search bar

I have the same issue of the screen going crazy (starting a text, clicking on a song, without me touching the screen at all, etc). I noticed that this happens when the phone is plugged for charging and the battery has fully charged (and still plugged). When I unplugged the power cable, the phone does not act crazy anymore.

Some physics guy could step in now, I suspect an explanation on the lines of electrons and magnetism leaking out.

Hi. Had the same problem on my Iphone 4S and my son's Ipod 4. The screen was going crazy: we could try to click somewhere and it seemed to click anywhere making it impossible to use the device. We were rebooting to solve the problem but it kept getting back. After a while, we noticed the same as Happy 12, it only happened when charging but necessarily fully charged but only when using certain chargers and sorrily not Apple brand. As soon as we disconnect the Iphone or Ipod, everything returns to normal. It makes it scary to think that a charger can have an impact on the response of the screen ...
