[Q] Touch screen not responding - LG Optimus G (International)

I have a problem with my touch screen.. Sometimes it just not responding any of my inputs and sometimes it just "touch" anything he wants without me touching it.. first place it happened was while charging it with a "chinese 5v/1.2A" charger because i don't know why my original charger exploded.. (It was so loud that i thought something hit the ground..)
The problem dissapeared when i stop charging the phone.. until 2 days ago..
I was undervolting the cpu a little and when i finished the test (with no errors..) my screen when unresponsive at all.. the power and volume buttons worked, even the hardware buttons in the front but the screen wasn't working at all.. Turning the screen on and off for a while do the trick but only for a few seconds..
It happened in stock rom and artmod rom.. but i don't remember too well if in stock rom i was in solid kernel too or not so.. I really don't know if it's hardware of software problem..
Any help please.. ?

I had similar problem + ghost touch with my LG and I think that the problem is hardware.
The resolve of the problem is changing the display ( like most people with the same problem).
In my case after the replacment I have Ghost touch and wondering is this hardware or software problem.

thx i will have to deal with the problems until i have money to repair it.. uwuU..

Touch Screen Problem

Hi All,
I am using an IMATE Pocket PC 2003 since the last 6-8 months. Over the last few weeks I am facing a problem with the Touch Screen. ALl of a sudden the Touch Screen fails to respond although the buttons are still working.
Sometimes after several reboots, the Touch Screen responds sometimes it doesn't. Sometimes I just keep it IDLE for 2-3 Hours and the Touch Screen starts responding. There is no fixed time of the error also the error is random. Sometimes everything is normal for one week and there is no problem at all. Sometimes the problem persists continously.
I have Hard Resetted it atleast 4 times but the status still remains the same.
If anybody has experienced this, do share your thoughts.
Regards
Jinesh
I read somewhere that if you re-align your screen it may help.
Do your hardware buttons still work? You could try mapping tpenable.exe to a hardware button and select this when the screen locks up.
Touch screen problem
Jinesh,
did you ever manage to fix this?? This is exactly the problem I've been having on my MDA Compact (Magician) for ages: screen unresponsive, buttons still working. I started a thread on this topic as well and got some suggestions, but never managed to sort it out. I'm a bit wary to resort to flashing a new ROM or something like that since it seems to open up a whole new set of potential problems and will cost me my warranty with T-Mobile at the least (Not that they're much help, but still)...
Thanx,
Joost
Maybe the cover
The Qtek9090-screen is sometimes locked (e.g. when it's in a car holder which causes too much pressure on both sides of the display.) The same happens sometimes without any cause - pressing on both sides unlocks the screen.
Hi,
I am using an O2 Mini now and have sold off that Imate. But what I came to know that the touch screen problem was due to the irregularities in the network. The screen stops responding fast when network is weak and the device keeps on searching the network.
I have faced this problem once or twice in my O2 mini also.
Regards
Jinesh, I don't know if you checked out my thread on this, but indeed this is the conclusion I've reached: bad network causes the unresponsive screen. I think it might have something to do with the priority windows gives to the screen routine compared to (searching for) network. As of yet I have been unable to find a way to increase priority for the screen or lower it for network, though I browsed through the registry pretty extensively. Suggestions from anyone on this would be most welcome.

Touchscreen problem with WM6?

Hi, to all!
I have a problem with the touchscreen of my hermes alias O2 trion.
When starting from cold state the touchscreen works normal. After some time the screen reacts not allways and shortly after that it does not react at all. Reset does not change anything.
Is it a upgrading problem or is it a hardware problem?
Here the hole story:
I bought a used device with Win Mobile 5 on it. At the first try out it worked, but afer some time the screen did not react to my stylus at all. After a reset it worked again so i dit not pay much attention to this and upgraded to official Windows mobile 6 (which was downloaded from O2). Update worked fine.
Then i ran a rom update on the computer to change the start screen. The tion disconnected (update stopped at 0%). Little shock, but the trion still worked. The program and radio versions did not change.
First thought: this was no official update, so trion did not accept it. Was something installed or was everything blocked?
Could this make problems?
What do you think?
Thanks
i think this problem:

Did you try to re-calibrate your screen? It could be a question of the screen loosing calibration so bad that when you press it, it works but you are not HITTING any buttons, because the calibration is off...
I have that problem with my Hermes, I need to recalibrate several times every day, especially after sliding out the keyboard (since the screen flips then) .
There's a very nifty short-cut to the calibration app: press the middle button on the D-pad while pressing the messaging button to go to the calibration screen, then press the middle D-pad button to launch the calibration (same as pressing "calibrate" with your stylus).
There seems to be a lot of Herms that have serious calibration issues. I'm personally so tired of it I am thinking of buying something else.
Good luck,
Laz
It's KNOWN hardware issue where the processor heats up and *somehow* transfer heat to the digitizer which make it unresponsive. I got a Hermes just like that laying around. Can't fix it.

Thanks!
Today the touchscreen worked good. Even playing spider solitair was possible. Then i pluged it into power supply and the device got slightly warm. The touchscreen did not work any more.
Could be a heating problem of the prozessor like Mikro_ Tech described. Thanks by the way
How can i be sure it is this problem and not something else?
@LazPL: That was one of my first thoughts as well and i did.
When the Touchscreen works, it works just fine and accurate. Then it behaves strange (sometimes not corresponding to touches, programms close all of a sudden) and shortly after that it doesn not work at all.
@the_passenger: The Hermes Version is HT 626... Anything special to this, because the link just lists screen allignment issues for this modell?
What do you think of the solution from the link LazPL posted?

i have the exact same problem with you and i think is screen related.
i ll perform the proximity sensor check and if it is not the source of the problem,i ll take off my screen,give a cleaning at the connections and put it back on, to notice it s behaviour.
hope i won t break my screen cause it happened before:fingers-crossed:
my screen has started un gluing from the left side of the display and screen is lifted upwards ,i just mention this for the possibility of causing a problem with those freezes during incoming calls,but i can t think of anything.
probably i need to order a new display(not from the same seller of course) cause it is a little dim too,if it s not fixed after trying those i really don t know what i will do with my phone,it really gives in my nerves with this problem(otherwise i m very satisfied of owning it).
i ll come back reporting after making my tests...
EDITroximity sensor check OK,no problem.
cleaned the connections of my screen and i have only 1 freeze after 40 calls,but is still there and is only a day that passed..
i can t target if my problem is hardware or software,i ll flash stock lollipop with flashtool and wait for some days,but if it appears again what should be my next step?
any ideas welcomed..
EDIT 2:after five days on stock 5.1,problem seems to dissapeared,so i supposed it is related to an app...
EDIT3:till now everything is OK.

Samsung Galaxy Grand I9082 Safe Mode problem after changing the touch screen.

Guys i just got problem with my Mobile i have changed the touch screen few times from repairing shop but every time it comes with a new proble. i just bought a new touch screen from the hardware shop and replaced it by myself. now touch is working fine but there is another problem it just starts in safe mod. i have restarted it many times but the problem remains the same. i checked it with the old touch panel and mobile starts in normal mod with that. can you guys help me out with this? I will be thankful to you guys. Sorry for my English.
I think you have bought an incompatible screen. try connecting older ones or buy a new one
While rebooting the phone keep tapping the left most button (what ever that is called). There is a Youtube video too.
I too faced a similar issue after replacing the screen and happens when you fiddle with the buttons when the phone is booting up.

Touch screen freezes on my LG G3

Hi all!
I have a 2.5 years old LG G3 black and since Saturday the touch screen doesn't work very well.
When I unlock the phone the touch screen works fine a few seconds (2-5) but then suddenly it doesn't response to my touches, no touch feedback at all. It seems like it freezes... But the rotation and volume settings by the hardware buttons work fine all the time, even if the touch doesn't react .
I did factory reset and brought it to the repair service, they told it's the display and replaced the whole front part of my phone, but after couple of hours using it, the problem appeared again... No idea why, maybe it's a software problem and a reset to kitkat or an older version would help, but I haven't done any software update for a long time, so I don't think it has been caused by an unstable update or similar...
Using Android 6.0 the official one, no ROM.
Do you guys have any idea ?
Thanks a lot for help.
