touch screen not responding - LG Optimus Black

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?

diamond2 needs reset to wakeup! Please help!

Happened this morning, I noticed that my diamond2 is not responding when pressing the power button as usual... black screen!
It wakes-up in two cases:
1. soft reset with the stylus.
2. removing the battery and putting it back then pressing the power button.
This happens after I leave it turned off for 5 minutes. It is working fine as long as I don't turn it off. When it is off 5 minutes then no response!
Note: I am using the latest htc rom.
Don't know if this is a software or hardware problem. Any help is much appreciated.
I have actually had a fairly similar problems with my TD2. Not regular and not at spercific times like after 5 minutes but there have been times when my screen doesn't want to turn back on, the device is still on because it still make some of the regular sounds, eg the ping on the home button but the screen is dead.
Like you it will only wake again after a battery out reset, sometimes after several attempts.
I'm pretty sure this is hardware related as like you i'm on an official rom. The first time this happened was after using the phone as a modem and it got quite hot so i think perhaps heat is loosening the connection to the screen, only a guess though so any other opinions welcome.
After trials for 8 hours, I figured out a work around.
I Forced the mobile to work in the GSM only band, from that moment, it is back to normal... 3G is important to me, but I think I will wait until the WinMobile 6.5 is out for our TD2... may be this will solve the issue!
Hard reset it at least once..... That may take care of the freezing issue.

Problem solved
As I guessed, it was a network error and problem sovled after changing my Sim Card and getting a new updated one from the Service Provider!
Now my TD2 can sleep well and get back whenever called
6.5 is out, has been out for a while now for the TD2...What are you waiting for, might solve this issue...gogogo!

I am afraid I have to bump the thread.. I received my device from the HTC service with a new 6.5 ROM installed, and I started having this problem. The deviced sleeps and does not react to pressing Power button, neither to pulling the stylus. The only way how to wake it is to remove the battery and switch it on again. Any idea how to solve this?

My TD2 starts the same problem . After some standby time the power button stops working. I tryed to re-flash ROMs , Hard Reset, Change the battery, and nothing solve the problem. The Power Button not working! The only way is soft reset... Any idea?
This is referred to as the "Standby of Death"
The only fix I am aware of is to flash a custom ROM.
hello guys. there is no need to flash a new rom. i had same issue, but hard reset and backup restore helped me. try this on your phone. for back-up, use sk tools

[FIX][08.04.2011]Patch for "Screen won't come on after device wakes" (RHO_S2_00895)

[FIX][08.04.2011]Patch for "Screen won't come on after device wakes" (RHO_S2_00895)
Problem: Device doesn't come back from suspended mode. Pressing the power button, sliding out the keyboard or taking out the stylus does nothing.
Occurrence: Random.
Quick fix: None known.
Request: Kinda all over the Rhod forums.
Affected ROMs: HTC Stock S2 2.07, all custom roms based on 2.07 drivers. Probably 2.10 drivers are partly affected too.
Patch:
For stock roms (standard HTC patch package, .exe)
For custom roms (download this if you're unsure, works for stock roms too)
For cooks (extract and put into OEMDrivers)
Thanks!
Let's see (in time) if the SOD's are finished for us.

.......Done
Installed. Didn't work . I think the flex cable is crapping out. Also had the problem where if the screen was fully slid, it'd black out. Now it's been like that every postion.
Although, the power button works to turn the screen off, it won't turn it back on.
It doesn't work for me either
The only thing that I was able to install on my Tilt 2 (latest stock ROM) was this file Jackos RHO_S2_00895.cab
Nothing changed.
The screen goes on but what stays off is the backlight and the only way to get the backlight to stay on in a reboot. Then try to adjust the brightness from the settings menu and moving the slides doesn't do anything. The brightness stays to the max no matter what.
Is it the light sensor? can it be disabled or checked somehow?
Thanks anyway I hope your fix helps others,

Does it sometimes don't come back or always?
SoD, Sleep Of Death, so called the hangup issue does happen only after the device is suspended for a long time. It does occur kinda often, but not always if you turn off the screen. If your device never comes back from standby it isn't a problem with SoD for sure.
That would be my [email protected] cable....

The exe file (for stock roms) is intended to work on Europe roms. I have no knowledge of HTC releasing this patch for other regions.
It's no fix for any problem with the phone The patch doesn't even touch the backlight thing.

It happens all the time. I turn the phone on via the power button. Boots up. Let it sit till backlight goes off. Press power button, nothing happens.
I can turn the phone on, press the power button to turn the backlight off and when I press it again, nothing happens.

I do not think it's a flexcable problem. If I can turn the screen off and power on the device with the 'power button', it has to be something software.
I have to check again if the device comes back on, but with really really low backlight.
It's annoying, I have to restart to see a text, missed call, etc.
Thanks for your help so far.
Won't wake up
I tried loading this patch after doing yet another hard reset to try to recover from these outages. It doesn't work. Within an hour of installing it, the problem came back. My specific problem is the system goes to sleep after a minute, and it usually comes back with the power button. But after normal usage for awhile (sometimes hours, sometimes weeks without a problem), it goes to sleep and needs a red-button-reset to turn back on. Then as soon as it goes to sleep again after powering up, it's off forever. The only real recover after reaching this "cycle of death" is a hard reset (full memory erase, back to factory settings). Then it will work normally again for awhile.
I'm not sure if this is exactly the problem the other submitters were seeing, but it is surely related.
I'm off to do yet another factory reset. WM 6.5 is not worth a tinker's damn.

It's a pity that it doesn't work for you. This is a patch for Europe branded devices, I don't even see the fix at any other region-based HTC support site.
Personally I never experienced SoD, so I cannot guarantee that it does work. All I know is that this fix is supposed to help with "constant hang". Whatever it is. It's a official fix and I didn't encounter any problems with running it on my Europe branded Rhod.
Jackos is this in your ROM? I have found several times my TP2 needs a reset as the power button does not bring it life. If I take the stylus out (when this happens) the row of keys light up, but still the display is blank. I assume it's already in your ROM (Jackos S3 1.1.2 SleekBASIC) otherwise I would have installed it.
It's going to be included from version 1.1.3 and up.

So...how do I uninstall it? I am on sprint in the US and have the latest official win 6.5 ROM and downloaded this update on my phone through a tech website and after installing it none of my keys works except for the power button. Apparently being for Europe it has corrupted my phone and none of the talk, end, windows, back or keyboard buttons work now. I need to revert this update, is there a way without doing a hard reset. I don't want to reconfigure all my settings that aren't backed up.

If anything really fails, navigate into /Windows/ directory using your favorite file manager and "delete" those two files:
Code:
debuglog.dll
HtcPm.dll
Probably deleting the second file should fix your keyboard issues.

[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.

[Q] Back and Menu button not working sometimes.

Hey guys,
I don't know if anyone else has experienced this, but the back and menu buttons stop working suddenly. This has happened to me twice. A simple On and Off fixes this, but I wanna know if theres a proper fix for it? My phone is rooted with the stock ROM "KKA". Anyone else experienced this?
My phone is NOT rooted with the stock ROM "KKA" and suffers the same problem.
Mone rom is rocket v17 , i got the same problem 2nd time.AND screen didn't wake up.
I have had this issue once so far, rooted with official Arabic Rom. does anyone have a solution?
had to restart the phone to bring it back to normal.
Read on Androidnz blog that this happens sometimes using spen with button press for using menu features like pulling up menu or back button etc.
I'm rooted, standard ROM, rarely use the SPen (haven't got around to understanding what I can do with it). I've had the unresponsive Back and Menu button problems a few times - only solution I can find is to switch off and back on again.
Good to know that it's not just me, but it would be nice to find a solution.
Same issue. Stock rom. Happened to me just now and the stylus was not being used at all.
well i also have that problem. i also know others with this problem.in my case restarting the launcher helps.ofcourse if u have both home and back button not responding at the same time then its not possible.i get both of them not responding at the same time very very rare.at that time all i do is turn of the screen and wait a few minutes.thats all,every thing is normal again.oh one more thing i think its a good idea to keep more than one launcher installed and not making any of the default.it helps switch between them easier.switching between launcher always helps in these not respondig issues.

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!

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
