Hello. I've had this device for awhile now and it's probably the best phone I've ever had.. except I started to have problems with regards to calls just recently. I actually rooted the device about 2 months ago and am currently using the Rombie mod v2 (JPC), if that helps. Anyway, the problem happens in the middle of a conversation, where the proximity sensor somehow disappears and the speaker mode is activated on its own (or maybe it gets in contact to my skin, I'm not sure, since the screen is supposed to remain blank). After that, the device becomes unresponsive: the touch sensitive menu and back keys don't work, and neither does the screen itself..but the hard key home button works and I could still hear the other caller via loudspeaker. I force a reset and everything goes back to normal (I mean this call issue doesn't happen all the time). I don't have any screen protector to affect the performance of the sensor. Anyone can help me out with this? Thanks!
Hello
One night I was using the phone without doing anything special , some video watching . Phone went dark, tried to reboot. Blank Screen and the capacitive buttons flash. Left it to charge all night, in the morning it started but after I pressed the lock button blank screen but phone still working and receiving input.
Took the battery and SD card out left it for 30 seconds then started it again, Stuck at LG logo. Repeat , phone started ... Pressed lock button once then again to unlock , screen wouldn't start.
Used LG Mobile Update recovery tool to restore it ... Didn't solve problem. Sometimes it does not even start , just flashes buttons, other times it does without screen and last all works even the screen until first time goes dark , in the last two cases I can use LG On-Screen Phone without trouble, in doing so I installed a proximity sensor test app to see if it was causing my screen to not come back on , the sensor looked fine.
Facts:
1. Two day old Optimus Black p970, worked like a charm until stated problem
2. The app that checked proximity sensor showed the sensor to be free when my hand wasn't on it
3. The warranty laws in my country are idiotic so I would do or buy anything rather than send it so they can give me a new one in 3 months.
4. Tried another battery from another Optimus, fully charged nothing different.
5. Stock rom.
Do any of you fine people have some ideas on how to fix this? Thanks in advance
Hi there...
Sometime ago [1 year and a half or so~] I worked at a cell refurbishing facility [there were samsung, motorola and palm devices from sprint] and that problem you have was quite usual. Blank screen, still the phone is somehow usable like reciving calls...
There's this thing called "flex" which is the connector between board and display and that is what we fix, most of the time not even "fix it" just getting it in the right place...
This happen because of excesive use in those sliding or clamshell devices, in OB could be for overheating, you could try to fix it yourself or pay $20 usd [that's what it cost here]
Would that connector explain the fact that sometimes it doesn't start at all? hmm I am thinking now and I guess if it moves and somehow the phone feels it has not display connected it could fail to start... Anyhow thank you
actually yes, it could be only for the flex [some devices don't start at all when not having display or keyboard if there's any] but since our OB is not sliding nor clamshell type probably was overheating.
you say you have stock rom, well now I'm using CM7 but when I was at stock and after using the phone a few minutes it felt warm and some more minutes [like playing gunbros where you need to use both hands and a lot of movement] it was really hot and had to stop playing for a while.
what I'm trying to say is that because of overheating flex could have moved, but because of overheating too may have move something else, you couldn't belive the huge number of micro-things that reside in the board.
so if it's only the flex, it's an easy task to do, just unplug and plug again, but if it's something else it's quite hard to know just looking at it, you need to do some electric measures and stuff, the recomendation is to take it to a tech center or something
Hi. I Have same issue. Two times when i press power buton, butons flashing and screen still black. Phone not responding. I must remove baterry.

Hi there, got the same problem too with my optimus black. Screen goes flickering, shut down don't do any good, and the phone temperature is kinda hot. But in my case it work after I clean some cache and data in the phone storage through LG OSP. After that, the phone temperature back to normal and the phone screen back to normal also. I believe that in my case the phone is overheated.
Hi everyone, I was hoping I could get some help with my LG P990 (Optimus 2x), I recently changed the screen and digitizer (it was broken so I replaced it myself with a new original one).
The thing is that since then sometimes the digitizer just stops working. The screen works, the buttons (screen lock and volume up and down) works, but the touch screen is dead. Obviously I can't reboot the phone so I take off the battery and put it back, the phone shuts down, reiniciates and there it goes, everything is good again, working perfectly... until it stops and the whole thing goes like this over and over...
Any clues of what might be causing this? I think it should be something software related since the digitizer works PERFECTLY until it kinda freezes... but I'm not sure, really not a smartphone guy so...
Thanks a lot!
P.S.: Tried to use the developer tools > locate pointer function and touched everything everywhere accross the screen and it's fully working, no dead zones, so the problem is "random" i mean it just stops working randomly, and I also didn't notice any patterns like "it freezes when i'm doing something specifically" it's totally random, happened when receiving a call, when making a call, while playing a game, while just browsing through the menu, while trying to unlock the screen... at least APPARENTLY random, maybe something i didn't notice if I do, i'll add later...

I have EXACTLY the same problem. Did you fixed it?
Has anyone had issues with their Z3 compact screen becoming unresponsive to touches? This happened to me last night even after hard shutdown via power button + volume up key.
My phone is encrypted so after restarting, I was stuck at the code unlock screen but the touch screen was completely unresponsive. After a few more hard shutdowns, a few hours off and alot of cursing, the touch screen finally started working again as if nothing was wrong.
Any ideas guys? I don't want to send this phone in if this was a one time thing, but I'm afraid it won't be the only time...
I guess I'm the only case of this happening?

It can occur for lots of reasons
This can be only software lag instead of touch panel problem.
and even 3rd party app can freeze your phone like this.
anyway the possible solution and way to understand if it s software or hardware problem is to repair firmware by PC companion
:good:

The reason I don't think its software related is because after the reboot my phone goes into the device encryption unlock menu right away. This menu theoretically should have little to no software loaded at this point, yet it still didn't response to touch. Now, I did recently downgrade from the latest UK ROM to the next available U.S. ROM. Not sure if that may have affected anything...
No more problems yet though...

Was the phone wet? Water can mess with the capacitive screen but shouldn't still be a factor after drying it with a rag. I'm assuming you realized this already, but doesn't hurt to double check.

Screen is not the issue… its the system

My Z3 do this too.. i dont know what to do
Same here. Happend 5 minutes ago and since no response from the phone -.-"
I hope it settles itself again.
Edit:
Now it works again. Strange behavior
I just returned my Z3c because of a touch screen malfunction. But in my case, it wasn't unresponsive, it just went nuts. It located taps at totally different spots from where I was touching, so typing, scrolling, etc. just was impossible. Luckily, this state only lasted for a couple of seconds up to a minute max, but occurred several times a day. Phone now exchanged for the "big" Z3 (due to arrive tomorrow), hope it hasn't the same issues.
I have found the reason my phone was unresponsive. I disabled some apps through adb, one of them seems to have caused the issue (dunno which though).
So I just restored the phone using the pc companion and since then no unresponsive touch screen.

Z3 Compact top half of touch screen not working
The top half of the screen of my Z3 Compact doesn't register any touches anymore. The bottom half is OK.
The phone wasn't dropped or anything. I did a repair with PC Companion and nothing, still the same....
Sigh!
hello, well the same thing is happened to me but my phon is z3 dual, this happened just before hour ago
Any solutions ..
I've just bought it about 2 weeks ago
I have the same problem, the touch is not responding and I can't use the phone since yesterday.
did reset by buttons and also by that yellow reset button and still nothing, it powers on but I am stuck when it asks me to enter the PIN code, because the touch is not working.
Anyone got a solution for that?
Which apps you have disabled on adb and say cause that issue?
Same trouble over here. Experimenting this unresponsive touch panel since today, several hours without working at all. I just blocked some boatware apps, but this should not affect touch panel, right?
Just restored the whole phone using official from Sony PC Companion software. It remains the same trouble with touch panel.
Today, in house, we put the phone under tap water just a blink. Do you think this could have damaged the device, though is water resistant? Do you know where are the humidity sensors, that could have change? Thank you for helping!

Hi all, I have an old Sony Xperia V that's been working perfectly for a good few years now, but recently it's developed this infuriating problem with the touchscreen, where it randomly acts like somebody is holding down the onscreen back button, and you have to turn the screen off and then on again to make the problem go away. Sometimes it also does this with the homescreen button, but most of the time, it's with the back button. This problem has gotten to the point that the phone is almost unusable, as it does it every single time I turn the screen on, if I turn the screen off and then on again (as mentioned earlier) the problem usually goes away for a few minutes, and then comes back again, making the phone extremely frustrating to use. Any ideas on what the fault could be? I've never put custom firmware on this phone, and I've never used it underwater. I've cleaned the screen many times with no effect on the problem, and I do not have a screen protector covering the display.
