Screen doesn't respond to the touch

---

Well, it seem every phone I use in last 6 month getting this disease when you swipe or touch on screen and nothing happens, or when you press one key on keyboard and it inputs completely different character from opposite side of the screen...
Just now I had the same exact crap going on on Nitro!
I pressed and hold on back button on the gb keyboard and it was acting like I'm pressing random keys at 50 keys per second!
But before that I had trouble unlock the phone, since the slide off motion didn't register at all, the slider would move a few pixels and go back.
The weird fact is the most noticeable this occur when phone is plugged in and charging, unplug it and problem usually goes away or at least become manageable.

What the hell I'm doing to these phones that causing this? Actually this is the first phone where I f.k with the system files, all others I either used CWM or market, nothing else.

I have not had any touch screen issues with this phone other than its just a hair less sensitive compared to my captivate.

V@no, are you a ghost? I have heard that sometimes phones will act strangely during use if you are a ghost. Something to do with spiritual electromagnitism. This would also explain why you are having compass issues!

Okay, so back to being serious. I've had the EXACT same issues you speak of when my phones (yes, this has happened to other phones too) were connected to 'dirty' power.

What I mean by 'dirty' is either a power supply that was very low quality or using a USB cable that the phone didn't like. Just recently my Nitro was acting erratically while I have it plugged into my computer. It shouldn't have been a problem because I was using a high quality, well shielded Blackberry branded cable (worked perfectly fine with my Nexus One), but as soon as I used the usb cable that came with the Nitro then everything worked correctly again.

Hope this helps!

Just got the same problem. Tried everything listed here to fix it. No luck.

Any other suggestions ?

I've found what Namuna said to be true. Also, I experienced this issue with my phone plugged into the power strip on the nightstand. Apparently there is a grounding issue in that power strip.

Could be it. I use a power bar also. Plus I think I'm using a cable from a galaxy nexus now that I think about it.

Maybe I'll try to find an official lg cable.

Thanks again.

I haven't had a complete loss of touch responsiveness, but I have experienced the erratic behavior; but only when plugged in and only while charging in AC mode. I've noticed this a lot more since I dropped my phone with the charging cable attached... I can be in USB mode and the slightest touch will knock it off charge yet I have no touchscreen problems. Once, every now and then, I am lucky enough to get into fast charging AC mode; which is much more stable as far as touching and using while charging... but the screen is almost unusable due to the erratic touches. I turned on "show touches" in developer options and while in AC mode, it shows multiple touches in a horizontal line relative to where my finger is. It even affects my soft keys.

Happens with every charger I've tried; my original charger, both HTC chargers I have, and a charger I found a few weeks ago. I've experienced the problem in my house, multiple hotels, and a few other places; both with and without a power bar. Pretty much, what I'm saying, I'm sure I've been connected to a good grounded source of power, yet I still experienced those problems.

Out of curiosity... have any of you either replaced or had your digitizer replaced? I've replaced mine twice, and my problems began shortly after cracking the screen the 2nd time.

Well i tried the charger that came with my optimus g (using a power bar ) and it seems to work fine now.

One more thing i did was try it without my memory card for a bit. I don't know if that had anything to do with it also.

Anyways so far so good.
