Touch screen acts weird while charging

My BIONIC does this too. I can't type a text while it's plugged in because it's like a ghost is tapping his fingers around on my keyboard.

Interesting enough when I use my 3 foot kindle charger to charge my phone it works fine...

Get your phone away from any RF would be my first suggestion. Curious if you are using the USB cord that came with the phone or some other after market cable. If you plug it into the wall charger, with the same USB cord, does it still happen? And if it still happens are you using the charging adapter that came with the phone?

RFI (radio frequency interference) can certainly cause this too, but the greater cause is the charger blocks themselves. I have charger blocks from many different manufacturers which I've collected or bought at yard sales, including Apple, HP, Jawbone, LG, Motorola,Plantroncs, RIM (Blackberry), & Verizon, as well as several no-name ones, and nearly all create "ghost touching", though by far the Motorola charger creates the least.

And to address the second part, I use the original cable in most cases, although I will often use a shielded USB extension, but it doesn't seem to make a difference. I will do further testing to confirm or deny.

I will test my stock charger with my IMP1000 tomorrow and see how that affects it.

I was wondering why my phone always seemed to be a pain to pattern unlock while plugged in to my charger at home and in the car when full.

Thanks for the explanation. Hopefully they can find a fix sometime in the future....unless it cannot be fixed by software. :P

I've found a battery pull sometimes cures this issue with my OG droid. Not much of a help for the non-removable battery on the D4.

I have the same issue as well. Like when I go to type in my pin it enters in more numbers than I actually press.

Mine does this all the time, even with the supplied wall wart and usb cable. It does this off of any power source from usb.

Same here, mine does it about 75% of the time. I have not figured out why it does it some times and not other times. But it definitely does it most of the time. I hate having to unplug my charger just to unlock my phone, then plug it back in.
