Hello fellow G2X owners. Need some opinions from people with experience in tinkering with electronics.
My touch screen would lock up and would only become responsive after toggling the power button. Also, it would make random touches by itself while just sitting on the table. This made me suspect maybe a grounding issue. I was really praying that wasn't the issue because I bought this phone from eBay so I don't have a warrenty.
After doing a lot of Google searches I found iPhone users had similar problems in which they said the techs would clean and reseat the digitizer connector. I thought that would be my only hope of fixing this issue so after reading that, it reassured me this was something I could fix. I went ahead and broke the phone down and cleaned all the connectors since I had it open and then reseated them. This seems to have helped a lot but the issue is still persisting but thankfully on a much smaller scale. The screen still becomes unresponsive once in awhile and still makes random touches when the phone is just sitting on the table. Like I said, its not doing this nearly as much as it was, but I want to completely eliminate this issue.
Any suggestions would be appreciated. Thanks guys!

Just send it to LG and not T-Mobile. U should have warranty
Could you explain a little more please. This phone was used so I would assume it had a limited warrenty from LG that has run out by now. Also, when I broke this phone down, I didn't find any seals that would show evidence of tampering with the device thus breaking any warrenty. Makes me wonder if this phone was been opened before.

Has a one year warranty through LG and since the g2x hasn't yet been out for a year......

I bought this phone new, and I can't find the seal anywhere either, don't worry.
Just wondering if u have any case on the phone? I found a little bug on the Trident aegis if unplug the USB rubbery port and replug it after about 10 secs the screen wont work but when u unplug it it works again. Its hard to explain but maybe ill make a video on it if everyone wants one

Yes, I have that exact case your talking about. If that's really what's causing this, I'm surprised I haven't noticed. Even more surprised how a piece or rubber could do that. Strange though, I actually took the case off earlier before reading your post and haven't had a single issue in the past hour. I will do some testing of this theory.
Edit: after looking into it I releazied the rubber flap that covers the USB doesn't actually touch anything but the external housing. The audio jack cover however, actually sticks inside the jack port.

Ok I thought it was just me. Take something metal and touch the rubber to discharge it. Works for me for like a 1 week.

I, too, have been having this issue, as I posted in this thread: Link
and showed in this video:

At first I thought it was a software issue due to the randomness of the occurrence, but now I'm pretty sure it's hardware as a firm push at the top section of the screen often helps, as does a firm whack, but only for a minute or 2, tops.
Pressing power always helps, but holding it doesn't. Taking apart the phone and reseating all the connectors (I wasn't sure which one the digitizer was though, so I didn't clean any) barely helped.
Input is always appreciated
I found that g2x touchscreen acts crazy when used with one of my usb cables.
Looks and acts like a touchscreen problem.
Could this be related to your issue?
Are you charging or connected to computer when it occurs?

Low quality USB chargers / cables can cause issues, but I've only ever encountered that on my Galaxy Spica, and my issue appears both when charging and when not.
Not sure about OP though; don't want to thread hijack, but the issue sounds similar.
Naw, it'll happen no matter what. Been 24 though now without that case and not a single problem. If it goes a week with no case and no issues, I'm gonna sign it off as the case being the culprit. Hate not having a case. Not having a case is what forced me into buying a new phone.

Hold a metal screw on the rubber plug thing. I also rebooted surfing the process. This night be a gimmick but it worked for me. Try and tell us if it worked
Sent from my LG-P999 using xda premium
Naw haven't tried that yet. I'd rather just make sure its the case first, then I'll see about discharging any static built up in the case. I am currently in a very dry climate and would probably have to discharge it fairly often.

Ok well I'm glad I'm not the only one. Shoulda posted this find but I didn't know if it was just a user mistake or not.

Well after a week with the case on and a week with the case off, I can't really say it is the case. Its been well over a week since I've had any issues so I'm hoping that whatever it was has worked itself out.
Sent from my LG-P999 using XDA App
Well that's good it worked. Probably since u didn't use the case it didn't have any static stuff. Its hard to explain.

I just received this phone from ebay today and am having the same exact problem, no case, I've had it for only a couple hours, any ideas?
I do not know whether others have this issue and noticed the touch becomes a little unresponsive to clicks when the tablet is charging.
Wanted to know is this something only with my tablet or does anyone face the same issue its just I need to press a little hard to click scrolling and all is fine
Same thing happens to mine

U are absolutely right ..i was trying to figure out why my touchscreen was unresponive at times but not all the time ,when i stumbled on this post....i took out the charger and it was very smooth but when i put it back on the problem resurfacs...
I wonder why this happens
Same here for all my samsung tabs (7 , 10.1 and n8000 )

I noticed this on my Samsung Galaxy SII phone today. I figure it's that the capacitive screen is messed up somehow by the extra electromagnetic field of the charge coming down the wire or something. Maybe I have a "noisy" power supply. I might changing chargers tonight and see if that affects it at all, in case the charger is dodgy and creating some sort of line noise. Who knows.
If you hold the device firmly in your other hand (rather than, say, having it on a table) it seems to improve things a lot. After all, that's how capacitive works.

Yes it is how capactive work but it is Samsung's fault not to proper ground the screen , HTC products are well grounded and don't have this issues
Sent from my GT-N8000 using xda app-developers app
Well I thought so I was worried that this was an issue with charger or something but until its normal issue I am ok with it
I've had this happen on my Samsung devices when using no-name chargers, never with the official charger though.

It happens with the stock charger too and yeah it is Samsung's fault. I was quite surprised when I first noticed it coz the difference in responsiveness is huge.
Juat a quick note , after changing the charger the problem is solved , the problem is in the grounding of the charger not with the note itself , but the fact is that most Samsung chargers are defective , 3 out of 4 chargers that I have have this problem

last night, my phone was overheating. and then i'm trying to cool it down by putting it in front of a fan. when i use my phone, my scrolling is error. it stops when my thumb/fingers is not touching ( do you get it ? :silly: ) . on a normal phone, the screen keeps scrolling even if my finger/thumbs not touching and slow down until stops. but not with my phone. it just stops without slowing down...
can anyone help me ? :fingers-crossed:
sorry for my bad english
Try restarting??
And JB has higher inertia while scrolling. That means if you scroll lightly, it will stop very fast, unlike Gingerbread 2.3.x.
Also, a possible cause might be that you were charging. XL has a slightly aberrant scrolling response while charging, most likely due to the interference caused by the charging battery.
Yes. It worked
Btw, how did you know that xperia L has problem with charging?

Hi!
I noticed this problem with mine too. I was charging my phone and using it on Facebook. Scrolling worked fine but when mi finger was on the screen (just touching the screen, no scrolling), the image went up and down. It looked like the screen didn't know what to do.
But I was not using the charger given in the box, I was using an older one given with my Xperia Mini Pro from 2011.
When I use the charger given in the box, there is no problem.
I've seen this problem on X10 Mini Pro too.

I don't know where it comes from, sorry.
as far as I know, it happens with all chargers. But maybe it just escapes attention sometimes? The charging battery affects the capacitive touchscreen response.

When I saw this "problem" I let the phone charging with my "older" charger. But when it was finished, I tried it with the new one. I went on every application that need to scroll but all was right.
It may be something with electricity quality, like speakers which have interference... (That's just an idea)
yeah. It happens only sometimes. I suspect when the phone draws considerable charge from battery, and the battery from the charger, resulting in higher electromagnetic interference.

You're probably right.
Has anyone had a problem with their nexus 5 where the screen would randomly start pressing things? It usually happens multiple times and is very erratic. Contacted Google and will send back for a replacement just wondering if anyone else is having this issue.
Yap, me too.
Had it a while back but it seems to have stopped.
Sent from my Nexus 5 using Tapatalk
Never anything like that but what I have done a few times is my palm touches the bottom right of the screen when I reach for the top left corner while right handing it. Coming from an iPhone so I guess it took a bit to get used to the larger screen
I requested for a replacement to Google Play this morning. They send it this evening. I should
get my replacement early next week. Good service I would say.
I'm glad I'm not going crazy! This is happening to me too! Is there any way to resolve this without having to go through the RMA process?
Only While Charging
I'm getting some erratic touch behavior, but only when the phone is charging. I take it off the charger and it seems fine.
I'm not getting total phantom behavior, but when I swipe from home screen to home screen, sometimes an app will get activated. Same with pulling down the notification area.
It makes me think there's a charge leaking through to the display components somehow.
I'm going to give it a week and then RMA it if it doesn't go away.
I have it too
I have it too but only when I connect my USB to the computer...
It's sucks cos I'm an app developer...
Is there any fix for that?

Sounds like a dodgy USB cable or port.
Same issues with my Nexus 4
I notice my issue is mostly when my phone is charging or when I'm using my mobile hotspot. Tends to get extra warm when im using both. Which leads me to believe its an overheating issue (the heat is throwing off the digitizer causing it to maybe think its being touched?) Is anyone else noticing the same?
Yes, but only while on wireless charger and even then only sometimes.
I take it off, push power button twice and it's gone.
I'm also experiencing this if my Nexus 5 is charging using the original Wall charger and cable.
Still no fix for this? Really annoying, I need to unplug my phone to the charger so that I can use it again normally
Same issue here

This usually happens when you use some other charger/usb cable than the original one

I also have the same problem only when otg or pic is connected through usb
So when I plug my N5 into charge, the screen starts recognizing "ghost" touches and does its own thing. Like when its charging its distorting the electric captive touch... Anybody else having the issue?

I am. I'm suffering it with my Nexus 10 as well as my Nexus 5, in my N10 the problem is much worse.
Same here, although for me its more often for my screen refusing to record my touch than recording ghost touches.
This is the case for Nexus 5 and Nexus 4 I had previously.
BTW, you can use an app like this to help testing the issue.
If you aren't using the charger that came with the phone this will happen.

In my case this happens with the official chargers, both for the N5 and N10 :crying:
I have the same problem here.
I already had this problem with my Nexus S. Using always the charger received with the phone.
I've noticed that sometimes is more annoying than others. It doesn't depend on the charge level, if you are charging by PC or how many apps are opened.
I think it's a temperature related problem, and it is happening when you are using the phone "a lot" while charging. But I'm not sure about that.
Anyone has more information about this?
P.D.: Now I noticed that I was experiencing this problem. My charge level was 96%. When it reached 100% this problem faded away.
