Stock ROM or custom? Any overclocking?
The phone powers up if you soft reset, correct?

Well, I found out it was a small problem with the rom.
It was a custom rom, and I just installed a different one and it works flawlessly.
With the other one, the light sensor did not work either.
Also, I dropped my phone the other day, and a really small spring fell out.
And the back plain on my screen is loose and opens up easily..

Which ROM?

I hate to hijack this thread but i am having the exact same problem. Basically when i put my phone to sleep its hit or mess as to if it will wake. It seems to have started when i flashed Energy ROM. It was terrible after that, so I switched back to the stock ROM available from the HTC website and all seemed well at first. Now its back to hit or miss.
I cant really rule out a hardware issue such as a broken sensor or something because I'm not sure how the mechanics of it work. When i push the power button on top the phone wakes but not the screen I know this because the 4 lights on the bottom light up and the keyboard as well. I can hit the button repeatedly but it doesnt help. At other times it works flawlessly, but usually does not.
Can anyone give me a suggestion as to what it could be, or a way to rule out a hardware issue?

Exactly my problem!
It was perfectly fine for the first day or so before it started crapping out again..
Can someone please help us with this problem?
It's mind consuming and it's making me worry.
Until TP3 is out, I won't get a new phone ):

Well, the problem is discussed in great detail on the internet, but no one can give a definitive answer. ..
I've been a touch pro 2 user for exactly 3 days... My new HD2 from T-Mobile is in the mail... This is a un acceptable flaw with no real solutiion... Good Luck TP2 users....

Good luck to you.
I've had mine for over two years and it was flawless
Just one recent drop determined everything
Although I Must say, it was one hell of a durable phone

Yea, dont get me wrong. I really like the phone. Thats why I'm getting the HD2. Great OS and big beautiful screen. I'm gonna miss the slide out keyboard but I think thats what breaks these phones.
I'm excited that there's the possibility of running Windows Mobile 7 on it.

I'd like to try to help. But you never answered my question of what ROM you are on (and which one you tried previously).

I've determined my problem is 100% hardware related. If I open my keyboard and then grab the screen and tweak it while pressing the power button it comes onn 100% of the time. Sux, but at least I know the cause now

Every once in a while my phone would turn on and I wouldn't know why
But yeah, I think it is hardware related.
I previously used Energy then went to Jacko's.
Both were perfectly fine, just the upsetting sleep function and light sensor would keep the phone off.

HELP: Same problem Phone not waking up
Hi saw this thread and was wondering if anyone can help me.
I have an HTC Touch Pro 2 for some month now...
Using the following details:
OS Version: 5.2.21887 (21887.5.0.86)
ROM Version: 2.07..401.1 (80303) WWE
ROM date: 02/04/10
Radio ver: 4.49.25.91
stock ROM basically...
THe issue is that the phone doesn't wake or when using it just freezes/hangs.
Not much software/apps installed... and memory is good as well.
I just don't know what's going on...
Help please.
Thanks

I'd agree with the notion that its likely hardware related. I've flashed maybe 10 different builds of Energy over the last 7 months or so, and never once had and issue with the SOD (sleep of death) that I can recall. A bad flash can sometimes happen. But since you flashed another reputable ROM (Jackos), that somewhat eliminates the possibility that a bad flash is the culprit.
You can start from scratch, by running Task29 to format the ROM area of the phone's memory, and reflash the ROM. But this would be just to eliminate the possibility of a bad ROM flash. My gut says that you won't see any different results.
Running the phone "clean" for a while (to see if you still have the SOD) without any software installed or any other modifications will eliminate the possibility that any software or mods are responsible for the issue.

are you sure its hardware related? because my phone started doing this yesterday too...I had an energy rom from october, and it was really buggy. I am only able to keep my phone from sleeping when it is plugged in to some power, so i flashed the newest energy rom and still having the same problem...wont wake up from sleep
EDIT:
I dont see how this can be hardware related because everytime i soft-reset, the screen works again. this problem only happens when the device goes to sleep...

Any overclocking?
As I already mentioned, I never had any SODs on Energy that I can recall, except when using OCT (OverClocking Tool).

I have done no overclocking...I just flashed the newest energy rom like 15min ago...is there anything else I can do or check? it looks like the phone works still, just no backlight...

After flashing the ROM, maybe try running it "clean" for a day or two, don't install any software or do any mods, reg edits, etc. If you still have problems with the phone waking up with a new ROM, and no other software or other mods, than it may indicate a hardware problem.
And be sure to run Task29 before you flash the new ROM, if you don't already do that.

You guys should read the following thread:
http://forum.xda-developers.com/showthread.php?t=648134
You're not the only ones (by any means) with the SOD issue. But it isn't at all clear what causes the issue. Lots of different theories in that thread about various software or ROMs, with no clear solution.
Lots of conflicting info, but some comments on the thread suggest (as I mentioned) that Task29 may help (certainly can't hurt).

Nope, definitely not sure, especially after reading the thread linked above. But as I suggested before, Task 29, try a different ROM, and run it clean with no software or mods, and start eliminating the variables.

[Q] Answer phone

every other time my phone rings I cant answer it. The accept button just wont move?? is it just me or have anyone else had this error I have a dezire z

Do you have set CPU set to 245MHz @ screen off?

no i dont, why?

Well that could be one cause, maybe it's a bad app causing your phone to temporarily freeze? Can you slide it the other way and ignore the call?

Did you try flashing a different kernel?

why do you suggest this? how do you know hes using kernels? im just trying to see what your connection to the solution is -its quite a specific answer to a problem that hasnt really been examined. what rom is he on, etc before you can start talking about kernels -- so can you clarify?
accept button - do you mean the slider? if you have cmod - just activate settings to disable lock menu/trackball/ whatever --also you could try the no-lock unless you have security issues.
if no cmod -- theres apps to reduce the lockage -- that may help you get your phone calls but still doesnt fix the problem? you could try enomther's and his awesome extra ssettings app has all those options

Thanks for your help, well it is my wifes phone and it is fresh from the store, just a bunch of apps installed.
I will try some things and see if i can figure it out. And yes it is the slide button, can that be switched for a push button, Is it theme based or in the dialer?? hope you understand what i say.

If its a stock DESIRE Z and not a G2 then I think it's safe to assume its got sense on it and not AOSP. Did you try hard resetting it? (power down and pulling the battery for at least 30 sec) other than that id check for any OTA updates in the settings menu. OR if you're willing/know how, you can root it and run CM or virtuous. Both ROMs are excellent. If you do that and the problem persists, it could very well be a faulty unit. You have a lot of options!

I found I had problems answering calls when I had a specific make of screen protector on the phone. As soon as I took that off and went back to a previous one I'd used then it was fine again ! It's a long shot, but I thought I'd throw it in there.

Problem solved, An update did the trick, thanks for helping out my friends,

Phantom or Ghost Touch Screen LG Optimus G

Few days earlier I started to notice this problem after 5 months of use of my device. My screen starts rapidly shaking left to right and front touch panel stop working, it happen when I freshly open an apps. To temporarily fixed it, I have to press power button to turn off the screen. Is it a hardware or software problem?

Did you flashed any rom or kernel?
Do you use trickster?
Some people sayed that uninstalling trickster solved their ghost touches on the keyboard (may not work in your case).
I had a similar problem and was because of a kernel.
If you had modified anything try to use stock for a while and see if the problem persist

Stock, I guess I should wait for official kitkat. Dont have time thinkering my fone atm.

I was ghosts touches on my screen. One was pressed on all sides. To fix it I had to turn off and turn on the screen. I decided to change the touchscreen and the problem was fixed. Now it works ok.
Sorry my english.

I bought it on ebay. Screen+touch+ frame. This option:
http://pages.ebay.com/link/?nav=item.view&id=111278902215
But You can buy other options.
1. Touch + screen+ frame (medium dificult)
2. Touch + screen without frame (best option)
3. Only touch screen. (very dificult option)
Many people have told me that the best option is 2, without frame to not be taking off parts that are originally attached to the frame.
You can see totorials on youtube

Ghost Touch now keeps rapidly pulsing at the buttom edge of my screen (portrait) my phone is sometimes uncontrollable. I never thought this kind of newer high end device gets broken so easily under short period of time. I never experienced this from my good old Galaxy Y, Xperia mini and X8 that I accidentally deep under water even now still working in mint condition. So sad with LG products. I was planning to buy LG G Pad but because of this I probably get Nexus 7 instead.
Im going to sell this for $155
Reflash it again with stock firmware twice, problem still persist
Its now a hardware issue

Touch screen seems deteriorating overtime. At first Ghost Touch, then on the next day a dead touch portion just above the home screen panel where the ghost touch first occurred rapidly moving back and then after few days a ghost touch appeared again just below in the middle of the screen (portrait) then after an hour probably about 1.5mm size thickness dead touch. Now a I have 2 horizontal dead touch portion of my screen and probably more to come if I keep using it.

Few days ago i'v got first phaton/ghost touch problem. I used Omni 4.4.4 so
- reflash to clean OmniRom (try few kernels) - the same
- flash to Android L Preview - the same
.....
fu***
Install - ARTMod ROM so 99,9%of stock - and as for now all its ok.
Strange.
Update:
One day and zero problems.

OK, this is freakin' weird...
I have been running KitKat on my F180S pretty much from the time it got released (different versions: full stock, VDT, Sling...). Yesterday, out of the blue, my digitizer started getting crazy with ghost touches in the upper portion of the screen (around the strip where Q-slide apps usually are in the notification shade, or the clock area on a weather widget where most people have it). This made the phone 100% unusable, as it was constantly registering touches. Rebooted to recovery to do a factory reset, and the problem was persistent in the recovery, too (I am using PhilZ Touch). So, at that point it looked like a hardware issue to me. To clear my consciousness, I opened the phone, disconnected the digitizer, cleaned the connectors, plugged it in again. No dice. Still, I thought about reflashing a full stock KDZ, just for the heck of it (no root, no custom recovery, locked BL). Here is what happened:
1. F180S V30c KitKat - same problem.
2. F180S V30b KitKat (downgraded a notch) - same problem.
3. F180S V20n Jelly Bean - everything is working fine, no ghost touches. Huh?!?
4. Rooted V20n, unlocked BL (Mako method) and flashed CWM using FreeGee - no problem, everything is still OK.
5. Flashed my favourite JB ROM - no problem, everything is still OK.
So, the phone is now running on rooted JB, with unlocked BL and CWM recovery, with no touchscreen problems whatsoever. I may try going to KK again at some point, but will just leave it for now, as I need a stable working phone.
WTF??? I am just scratching my head, trying to understand where the issue came from. It appears to be directly related to KitKat, since eliminating unlocked BL and custom recovery didn't solve the issue, but going back to JB (either full stock, or unlocked BL with CWM) totally cured it. The most bizarre thing is that it started out of nowhere, as I didn't do anything to my phone recently, apart from installing some apps here and there...

Yeah... But at least in your case the problem seems to be consistent. I was using my phone without any issues, and then it just crapped out for no apparent reason. Nothing changed, same ROM that was working fine before...

It started the same way for me.

....
The same thing happened to me. Are you guys familiar with Sky Vega phones? I had a Vega Iron before and also it began having ghost touch issues after upgrading to kitkat. I was frustrated, i also flashed any custom rom i could search and no luck at all. I just sold it recently! and i heard this ghost touch issue is also a common on Nexus 4.

Hello everybody,
I have the same problem with my LG - ghost touch and dead zones on the display. First installed the ROM from this link - http://forum.xda-developers.com/opti...te-10-t2811342 , but the issue still exist.
Then change the display with a new one. Dead zones vanished but ghost touch doesn't. Tried some other ROMs even the original stock ROM.
When I installed the new display the ghost touch is mostly when I use Facebook Messenger.
What can I do in this situation?

Touch Screen issues?

So has anyone found out if the touch screen issue is a software issue or a hardware? Is LG going to offer a fix or are they ignoring the issue? I have a Sprint LG G4 and the touch issues get quite annoying. I've been reading up on the issue and have tried everything but I still get miss touches.
I love the phone but hate this imperfection it has.
On a side not...when I get a text the phone vibrate (whatever vibrate setting I have it on) then it stops and my audible notification sounds. It does not happen simultaneously...is this normal?

not really I just have not seen any in the sprint section so I was trying to see if any other sprint users have the problem...Ill I see is verison.

It might sound weird (as I also thought it was before I tried it) but the way I got mine to correct this issue was by doing a factory reset (just from the phone settings, not a KDZ or anything). Since doing it my phone has been MUCH more responsive and has not been lagging out or miss-touching or anything.

Factory reset solves all issues.

Factory reset didn't fix it for me
Tomorrow I'm going into the T-Mobile store to see if they have any G4's present that do not have the problem and hope they will swap, if so.

Sorry man, Really wish it would have worked for you (It seems to have worked for quite a few people on here). Hopefully they will let you pull the old switch-a-roo then since this is clearly a defect.

What touch screen issues are you having? You need to elaborate. A video would also help. I've had my Sprint G4 for about a month now and I don't know what these "touch screen issues" are that everyone is complaining about.

This problem occurs in all variants -

[Q] LG G3 Screen problem ? (video)

Hey guys! Since last week I've been experiencing some weird problems with my LG G3 d855 screen blacking out, everything was working OK, the last thing I remember installing was Opera Max,
don't know if this have to do something, BUT I've didn't dropped my phone or anything, It was working at all times, maybe it's time has come?
I've factory reset to see if solved but no luck. I attach a video so you can see what the problem is, it doesn't happen at all times, I can still use the phone normally and a few times a day the problem appears.
Can someone confirm I have to replace the whole screen? or is it something else?

I chatted with LG's customer service and they basically denied the existence of any systemic problem.

OMG so many people with the same problem. I've readed all the posts on ac's forum, most of them complaining about LG customer service and how about they even know what the problem really is.. And in almost every case problem appeared after the warranty ended. Awful experience with LG.
