Touchscreen while usb connected...

My Touchscreen Don't work correctly while i connect it with The Computer ...
Any idea?
Sent from my MB525 using XDA App

Happens to me as well. No idea why either.

It happened to me when I connected my Defy to the Apple's Greenpoint charger.
So I think maybe there're some problems with your USB port or your data cable.

With some SBFs i dont't have this Problem!
This is magical

I had this problem when I started using the phone. After wiping it vanished.

it happens to me with some chargers but not with others. With original and with other LG no problem, but with another i have that problem too.

I have this issue too with samsung charger. I guess this is feature

I guess the problem from the usb cable it self because i have this problem before when i connect the phone with the original usb, the touch screen works properly but when i used cheap chinees cable then the touch screen become crazy

use advanced task manager it its probably helping in such matters , just end all and restart if any launcher u have already.

Touchscreen doesn't respond when connected to PC

Hello,
Today I have received new korean version of LG Optimus G and I immediately notice one problem. When I connect phone to PC via USB touchscreen stop to respond. The phone is not frozen, I can see that it's charging, the clock is working, hard buttons like VOL+ and VOL- and power button also works but touchscreen is unresponsive. This only happens when connected on PC or laptop via USB. Everything works when charging with wall charger. I've tried different cables, also on my PC and laptot, and always the same. Touchscreen doesn't work while connected to PC. When I unplug cable everything works well. I would like to emphasize that this is my third korean Optimus G. Never got this kind of problems with previous two.
Any solution or suggestion?
Thanks.

Anyone?

I can only say that I have never seen this on my F180 (but you also didn't have this problem on your previous Korean units). What ROM are you running on your phone? I am pretty sure the problem is not a hardware glitch, and is specific to the firmware. Flashing a KDZ or another custom ROM might be something to consider; other than that, I have no idea...

Tried 3 roms, Stock f18030c, Sling 2.2.2 and Artmod 5.3.1, and always is the same. Only when it's conncted to PC or laptop, on or off doesnt matter. When it's connected to wall charger touch screen works flawless.

So as I can see it's a very strange problem and no one can help me? Huh http://cdn4.xda-developers.com/images/icons/icon9.gif

Help!!!!!!

I`ve got a problem with my HTC that I can`t solve. First it wouldn`t charge, then the speaker suddenly turns on/off while speaking with someone. While texting, the messages suddenly disappear, so I have to type it again. Then my car navigation app turns on and off for no reason. I installed the antivirus protection and it`s still the same. Then I reinstalled the software , but still no changes. Has anyone ever had a similar experience, and what did you do to fix the problem? Thanks in advance.

R u tried charge your phone with another charging cable ??

Not charging, and randomly going to car mode; both indicate an issue with the MicroUSB port.

That would be my thought, yes.
Although I don't think it explains the other problems. Running the proper RUU (if OP's version has one) may be a good idea, and see if it helps with any of the problems.

MotoZ2play USB not detected on PC and Turbocharge icon not active when charging

i have a problem on my moto Z2play,
the USB on my Moto Z2 Play is not detected on the PC , and then the turbocharge icon is not active when charging the battery,
I have replaced the USB port but the problem remains the same, do you have motoz2play schematic layout? btw thanks for your info and more help

I was having the same problem until yesterday, the usb issue I solved by installing the motorola mobile drivers on my notebook, after reboot it (pc) my cellphone started to be recognized again. The turbo charging issue i'm still testing after performing a factory reset. I let the battery went 0% and the device turn off then when I put it to charge the "turbo charging" icon appeared, but i'll keep an eye on it, to see if it's solved definitely

thanks a lot
thank you for the information and advice, i will try it,
nice to meet you from indonesia,
btw do you have motoz2play schematic?

I had the same issue recently, turns out my USB port was dirty, just use some thin plastic to remove the dust and it shall work like a charm

Stock Pie Sucks
This rom has a lot of bugs...
YES, it won't even recognize the USB connection when connected on the PC.
Any of the custom roms don't have this issue...
EXCEPT that the custom rom experience another problem Stock does not suffer
Instead of the USB problem, they get distorted audio whenever a call is done
It is impossible to understand what people say with that much level of distortion...
Isn't there any ROM that doesn't have any bugs there?

Question How to fix pure type c(no dongle) earphones not working in poco f3?

I have been using my poco f3 for over a year it works perfectly except currently it can't recognise usb connection from pc it only charges even through it used to otg stuffs also dosen't work and lastly the earphone i bought 7 months ago dosen't work currently it used to work 2-3 months ago now it dosen't detect suddently one day it just dosen't realise for no reason when i connect it to a charger it charges but using the udb c cable with anything else dosen't detect when i connect my earphones it does that connect sound like a very low sound indicating the usb port dosen't seem to have a problem i am not sure so please help

Hey there! It seems to me that some of the contact points of the USB type c port are not actually making contact. Please try to use a brush or something similar to clean the port.
Do not use anything wet. The last thing you want is to cause more damage.
Let us know about the results.

Still dosen't work i already tried it the first day if i insert an otg with detecting light it turns on but dosen't do anything else dosen't detect or anything like it used to detect before and the light would flash when it started detecting the physical mouse also dosen't work
