[Q] Ghost Touching problem - LG Optimus Black

Apparently I'm having problems with my touch screen (including the 4 touch buttons), this doesn't affect any other function and other physical keys.
Now, the problem:
After few minutes (2-3 min) of usage the screen wont respond to any touch input and it also seems like a ghost is touching the screen even if i dont. If charging the malfunction appears more quickly. I have assumed that it is relative to the how fast my phone heats up.
What I tried so far:
Changed Rom - still the same
Reverted to stock Rom without root - SURPRISE, its still the same....
Can anyone help me? Is there something else I should try doing?

same problem here too
what i tried smartflash v 20g with recovery and without
flashed v30g with out recovery
same problem dont know what to do if hardware problem will last go in for screen replacement
if any one can suggest a solution would much appreciate by the way was on makay rom when problem started :crying:

Your phone is haunted! Dun dun dun...

[Q] Touchscreen not responding

---------UPDATE------02-03-2011--------------
Today after some time i noticed when playing with the camera a little response to the touch but it seemed random after that i ran the align screen program and after a few tries it seemed to work correctly, this is estrange since i had previously run the program quite a few times without any result.
I will continue the testing and inform you.
------------------------------------------------
Hello guys I just got a xperia-x1 to play with, but when i turn it off the screen is not working when i touch it either with my fingers or the stylus.
My first reaction was a hard reset of the phone which didn't work, then i tried installing android but the rom i installed asked me to touch the screen to start so i was stuck at the same place, after that i have tried flashing using some roms but the screen is still dead.
I think this is a hardware problem but is there anything i can do to verify it?
And what part should i get to fix it?
Unfortunately i don't know if the device has been in any kind of accident.
Thank you for your help.

[Q] display keeps freezing

Hello all,
My incredible s freezes, I would then need to press the power button (to put screen into sleep) and then wake it up then it's good again (not restarting).
Any idea whats this all about?
Did someone else have the same problem? what should i do next, how can i find out if its software problem or hw?
thank you all for the help
PS: i tried soft reset and hard reset, nothing helped, could it be that i need to change the touch screen DIGITIZER?
PS2: i was searching how to do a factory reset....
From the main home screen, tap menu
Tap Settings, then Privacy
Tap Factory data reset
Tap Reset phone
Enter your password if required, then tap Erase everything to confirm
in my Privacy menu i dont have Factory data reset, whats wrong with this phone? i just did upgrade, using Adroid 2.3.3, Sense 2.1, SW no 2.30.405.1
found out that the factory reset thing is in SD & phone storage menu
i did a factory reset but its still happening
help please
maybe a new display would fix this?
what else could i try before i spend money on this issue?
HBOOT: 1.13
RADIO-3805.06.03.03
Android 2.3.3 official ROM
should i try to S-off it and install a custom ROM?
im afraid that it might freeze and break

Is it under warranty?
If so I'd bring it back, if not i'd go the custom ROM route.
The fact that you can turn it off/on again and the issue is fixed makes me think it is software related.
I agree with scoobysnacks, i would do the same
most probably software related. i normally use "keyboard from android 2.3" app from the market, back in those sense 3.0 days it worked brilliantly but when i flashed any sense 3.5 roms, the a and k keys become not very responsive. the result?
my texts turn into something li(k)e this. no (a)'s and no (k)'s.
in the end i changed to go keyboard and everything works well again
thank you guys for the advice
as i sad before i hard-reset the device, and the problem is still there, even more i noticed that in some cases the upper part of the display gets numb, doesn't respond to the touch/finger ... again after i turn off the display and back on it works... also when i write texts (horizontal aligned) the left part of the keys aren't working or it just pushes the wrong ones.... i tried to do the calibration thing, but no change
i installed go keyboard and no change,
i just cant write 'w', when i touch the W in the go-keyboard it will write E or Q
whats wrong whit it?
i did S-OFF, and rooted the IS, now ill have to find a quick/light ROM to run on it
any suggestions? for a stable/ light and quick ROM?
ill do this test and if still nothing works ill changed the display, right? any other suggestions?
i did it, i flashed a custom ROM, Android Revolution HD
problem still exists
some more details:
when i keep it in landscape position, and try to write a message
the keys: w d x , are not responding, so every time i try to touch them, a neighbor key activated
any other solutions? before i go and order a new touch screen digitizer?
please, any other solutions? before i go and order a new touch screen digitizer?

Wondering what will you get if you use swype keyboard..
perhaps touch screen digitizer really need a change then if all not working.
I've got the same issue. The freeezing happens in all screens, and requires the power button to be returned to operational state. This is on a stock IS 2.3.3 ROM.
next i will try S-off, rooting and custom ROM, and see what happens. I can't see how this would be a hardware (digitizer) issue as it comes and goes. Is a little frustrating, and since I bought it used, I have no warranty.
Same issue here too i thought i was alone with that issue, posted in trinity forum.
I'm getting some random lock-ups even sensitive buttons and touchscreen don't respond, It goes away going to sleep and going back, it's so frustrating while web browsing for example
Am I Alone with that issue, or this is sign my CPU is dying?

Let's fight together with that problem
Well, completely wiped and installed a new ROM, still the same freezing issue. I've oredered a new digitizer, so we'll see if that works.
New digitizer didn't work either. Gonna try a new kernal, after that, I give up!!
Hi amigo, I face the same problem, maybe this rom is not very stable.
Tried a different Kernel, and still the same issue. I've tried everything I can think of and this phone still seems to randomly lock-up.

Sliding won't work anymore

Hey guys,
I could need a bit of help! It's now the third time I'm having this problem, don't ask me why. I've got the feeling that I read the whole forum here, but didn't find anything similiar.
The 1st time I didn't change anything (ok, rooted it, but nothing else)
The 2nd time I overclocked it slightly (~850-900 MHz)
Now I'm using MIUI.
But back to the problem:
I'm unable to use the keyboard, every time I'm sliding open the keyboard (even when it's turned off), it "crashes". The screen stops working or it freezes, the only way to turn it off is taking out the battery.
However, the bigger problem comes now: I'm barely able to restart it. It tries booting, but is restarting all the time or the screen is just turning on (in some angles you see that it is turned on but it's black). After many retries, it starts working, sometimes the bootloop is running 15min or i have to manually restart it 10 times or more. The strange thing is that the keyboard works fine, nevertheless I have to choose between using it opened (taking it with me becomes difficult ) or closed...
...the main problem now is flashing a new Rom, I'm currently trying it through the android sdk and adb, but using the power-button + x is easier
I don't think that I can solve the problem, I sent the device two times back (warranty till may 2012), but maybe someone here knows a bit more. My guess is that one of the sensors is broken, or some parts of the display that should manage the sliding process...
Anyway, thanks for your attention!

Tried to use one a time ago, but it wasn't working right....
However, now I'm not even able to boot it, the screen just flashes and turns off itself before trying to restart a few moments later....guess I lost my Milestone

the computer isn't finding it anymore...I'll back up the data and try use my warranty... I hope that they don't complain about MIUI...
But I'm still not getting the point, why my mobile had these issues three times, although they "repaired" it twice...and nobody else is having the same problem

touch screen not responding

I read already that a few ppl had this problem with different ROMs. I never had it before today. I switched the screen on and it looked normal but I couldn't do anything. I could swich the screen off again and tryed to press the power button long, OK shoutdown menu apeared but as the touch screen didn't respond I couldn't select anything. Well I pulled the battery out and it started normal, works good again.
Maybe I never have this problem again, but if it apears again might canging the kernel help or is it a ROM problem? I had this problem with JellyBam 4.1 so I could just use a different CM10 kernel.
BTW as I pulled the battery I have no log, but there might be a change to still get that log with ADB because the phone was still running just no touch response and that means (nearly) unuseable. I just have no clue how to do it, if it is posible could somebody tell me how to get that log?
Before pull out battery, try hold both Vol + and Power button until the phone restart (if it can, if not, then, you can pull out battery and forget the logcat ^^)

This appears to be a common P970 bug with 4.04+ ROMS. Loss of touch control, and long-pressing the power button brings up the shutdown menu which you can't access.
GB/2.3.4 ROMs don't have this bug. I'm not aware of any fix, save reverting to GB.

OMG somebody is still replying to that old post, over a year old, I don't even use that phone anymore, may last year I got my S3.
As I said, it only happend to me once with the JellyBam 4.1 ROM, I didn't gave to mutch to that problem with JellyBam, cause it was not the only one. That ROM was bs and didn't stayed long on my phone. It had everything, but nothing worked.
A lot GB and ICS ROMs worked well and even most of the CM ones worked rather good, they where just to power hungry. I liked all the Zeus ROMs, especially IZS. IZS is LG 4.0.4 based and was by fare the one I liked the most.

I shouldn't have replied to you. It's an old post. I should have targeted the latest post in the thread.
i think its hardware issue,,if i press and hold a little while on upper screen (right beside lg logo) touch screen became normal again. but sometimes need to hold on there when touch not work again. a member on this forum call it a flex issue of the touchscreen.
anyone know how much cost to replace it with new flex to fix this issue?

[Q] Help: Phone locks up often...

Hi Guys,
I have a serious problem with my Inc S. Lately, after using a few apps (mainly on the bus) the phone will go to the lock screen. A this point when the power button to wake the phone, it will just hang. The backlights will still be on but the phone is unresponsive. I have pull the battery out for 10-15 mins before it will restart. This issue happens at least 2-3 times a day. I can see no reason why this would happen. I have tried a factory reset but nothing works. Any help to resolve would be greatly appreciated.

Telling us your issue is fine. However, we need more information such as your bootloader status as well as what ROM you are currently on (if you are of course)
I have unlocked the bootloader, cwm recovery, but still running stock Rom. Haven't flashed a new Rom as yet. The phone seems to get quite hot, too. I think overheating may be the problem as it won't turn on for 15 - 30 mins after battery has been pulled out, which suggests the phone would need that time to cool? Dunno, just a thought.

Overheating is most likely your culprit. But its pretty difficult to pull the phone to about 50 degrees you really should watch whats running in your background and what applications you are running. Overheating may damage your phone and I assume you probably won't want that.
Would flashing a new Rom help? Never done it before.

Ok, so when the screen blacks out, I can still receive sms. I have turned the screen time out to "never" (as it seems to only lock up when it goes to sleep mode), but it still blacks out after say 1/2 hour and screen becomes unresponsive. Have to pull battery out for a while. Is this a hardware issue rather than a software issue?
This still an ongoing issue, and driving me nuts. When ever the phone goes to the lock screen or after a phonecall, it wont come back on. The touch still works (can play music, etc by touching screen from memory) but the screen wont show anything. Have flashed cm7.2, done wipes, etc with no luck. Any help?

Ok now that is not an overheating issue. That's probably a ROM issue or a kernel issue. I would suggest switching ROMs, maybe CyanVivoX or CyanVivo10.1 if AOSP is your thing. If not then maybe SVHD, Nik Project X Rebirth, or ViperVivo for Sense 4.1 (or Blackout or ARHD if you want Sense 3.6). Happy flashing
After a month of stuffing around and flashing my phone with different tons, I am still having the same problem. The only solution I have found is to install a wakelock app from the playstore, which isn't ideal as the screen stays on, drains battery and everything gets activated when the phone is in my pocket (mates are sick of getting phantom calls from me). The phone is no longer in warranty so I don't wanna take it to a tech.... There has to be a solution. Any further help woyl be greatly appreciated.
