Very odd touchscreen problems - LG Optimus 3D

I have been running ICS 4.0.4 v28b on my P925g for a couple months now. A couple days ago my touchscreen started being extremely picky.
When I factory reset the phone, touchscreen works perfectly until the screen turns off. the only inputs it will register are sometimes an unlock swipe and always the power down menu.
I have successfully tried a few resurrection guides but to no avail. I have done a few complete wipes with TWRP as well,
I have no idea what's going on. a little help or advice would be greatly appreciated

Check your power button. Could give permanent inputs. Try to click from time to time only the home button and see uf it mskes screenshots.

I apologize P-vlad, I'm a bit of a noob. How do you mean check the power button?
The screen takes input very sporadically. For example, when i have an incoming call, i can use the screen to accept or decline. After that I then have the use of my screen but no front keys. This goes on again until I hit the power button to lock it, then I have no use again.

It may be a hardware issue, i was looking through old help threads in this section where a user was talking about short circuiting the battery for the clock, i have no idea how, but that may be it?

HTC Touch Pro power on button problem

Hi guys, I find this quite annoying and wish there is a mod for this. I don't know about other HTC Touch Pro owners but i find my fone quite sensitive.........it's "EASILY" turned on by a single "SHORT" press of the power button.
I didn't even hold it for 1 second, if i suddenly press or tap on it really quick, for not even a second, it turns on.
In case ppl don't understand and tell me that maybe my fone was on in the first place but just have the backlight off, and with a single tap on the power button, the backlight goes back on again. I knew that already. But what the problem really is, is that it's totally off, and when i tap the power on button, it turns on, i.e it vibrates and shows the welcome screen and all that other startup animation.
Is there a way to increase the delay of the finger-press on the power button? Coz it's so annoying that it gets turned on when i don't want it to, especially since this fone's weakness is that it hogs battery even though i've already applied tons of tweaks etc to lower the performance and increase battery life......
Oh and i have another problem, i find the signal kinda weak, is there a program or tweak to increase the signal?? Coz on my old phone Sony Ericsson W950i, the signal is great and I never have bad signal problems with it. But using HTC Touch Pro, i have this problem. This only happens when i'm at Uni, but it's not like they have bad reception or signal blockers there like how schools or colleges have. Just that when i'm inside buildings and there're tons of other buildings around, i can't send the txt coz of bad signals and it's bloody annoying, but using my W950i works fine.....
also I noticed that when i type a txt message using the hardware keyboard, it seems to fail to send most of the time, but only when i'm in UNI. But if i switch to the software keyboard, the one that you use ur fingers or stylus, then when i send the message it often works compare to using hardware keyboard.......any ideas?
Problem No 1: Try Touch Lock Pro
Problem No 2: Try to burn the newest RadioROM.
thx but i'm not trying to lock my phone, so i don't think TouchLock Pro is what i need.......
My Raphael turns also on after pressing the power button for a little few moment. With touchlock Pro you can prevent that you mistake your Raphael. I hope you can understand what I write in my "own" english
Ok so i've got it installed now and went through all the settings but couldn't find anything that can delay the power-on button press, I still have this problem. The app is a screen-lock app, there aren't any options regarding to power-on delays.......
plz tell me what settings etc to use.
I've never said that you can fix your problem with TouchLock Pro. With this you prevent to use your Raphael when you press your power button accidentally.
ya but that's only useful when my fone is on and it locks the phone but i'm trying to prevent my fone from turning on in the first place if i accidentally press the power on button for not even 1 second, because then it will turn on and i don't want that.
same problem here...the phone I thought I had turned off was back on, because accidently it got touched by something else in my luggage.
The only solution which to me is unsatisfactory, is to take out the battery so that it cannot power up.
C'mon...there has to be a better solution than this, no???

wow yay finally someone else other than me also report having the same problem, boy am i glad to know that i'm not the only one having this problem, i thought it was just something wrong with my fone and not all HTC Touch Pros....
i can't believe there aren't any results on Google, no forum discussions or solutions to this whatsoever. Also, nobody seemed to report this problem or come up with a solution on XDA as well as other forums i use like PPCgeekz or WMusers etc.........which is odd considering how this problem is quite annoying, that if u suddenly power on the fone by accident, it can drain battery life and god knows HTC Touch Pro has a crap battery life.............
I think that htc has done a bad job testing the powerbutton on the tp2.
There are some other things like weith, thikness and batterylife that could be improved but the powerbutton issue is realy a BIG bug.
Why they didn't make a slidebutton or a timeout between push and activation?
A dobble tap on the powerbutton could also be a solution.
The next rom shoold have a improvement about this button.
People, please react on the powerbutten problem so someone can fix this.
Thanx

Leaving the Touch Pro (Raphael) for some minutes without battery will stop the clock. So, when you put back on the battery and power up the device, the clock will display the wrong time. The time when you remove the battery.
This is hardware related.
Can produced different symptoms though.
Facts Behind the Power Button
If take a look at the inside of the powerbutton, there are 2 points making contact when you press the button. If you press it, the software will recognize this and the screen will turn off.
If you press it long enough you'll get the "QuickShutdown" message.
But, if water/alchohol/liquid gets underneath the button, the 2 points may be making contact, because water/alcohol conducts.
The button is very weak. Due to this, it may not properly work if you have used it for a long time.
As a result, despite the fact that you hit hibernate/sleep/suspend on the hardware power button = yes, the screen fades to black. But IT IS STILL ON. That explains the battery being drained.
Solution:
Open the phone hardware. Clean the power button connector manually.

i heart everyone talking about the sleep of death and to be honest, i havent really experienced this, but i definatley do have an intermitent power on and off button problem on my touch pro 2.
i read on some other forum that it could possibly be the slider that is casuing the problem. but to be honest, the button its self feels fine and looks fineand when i does work it works a treat. i havent had any water damage done to it what so ever. so im not sure , i am new too all this self help mobile stuff. so please excuse my ignorance. Ive doen the usual hard reset, button works for a few hours then calls it a day. soft rest, was working up until this week. i cant get ot to boot up again, while fiddling with the batter and a power lead. but the power button is so intermitent its driving me nuts. id be so grateful if anyone could shine any form of light on this. thanks in advance

Phone doesnt wake from sleep

I just switched to my Touch Pro 2 and flashed Energy Cookie 2.5 GTX. I'm at work so I cant flash back to the stock rom or I would. Its also difficult for me to search the forum because everytime i want to use my phone I have to reset it
Basically what is happening is that once I hit the power button or the phone puts itself to sleep, it will not wake back up without being rebooted. If i press the power button then the back key, the four keys at the bottom light up. Also if I open the slide out keyboard the phone makes the xylophone noise. So its waking everything but the screen. I dont think its hardware because the screen comes back to life when you hit reset. It has to be a software issue.
Can anyone help me with this so I can get through this day lol? I would greatly appreciate it!

Try preforming a task29 and then re-flashing. Make sure to back up your data as this will erase the device memory.
Not to long read this posting : http://forum.xda-developers.com/showthread.php?t=648134
it called SOD = Sleep of Death, and as cajunflavoredbob suggest, do task29 first, everytime you want to flash a ROM.

[Q] Power Button Not Working

Hi guys,
I have a little problem where my phone's power button will not function in any way, long presses, short, almost embedding my thumb in it, all to no avail. This is doubly dissapointing as I have just installed the latest dexter plus patch to fix the problem. I still had the problem on the previous version and I thought a clean start may fix it. The only way I can get the screen on is to press the media play button! Which of course isn't doing anything on dexter.
Hunches:
I have been playing with a light sensor program and using a 3 second press to turn the phone off, I am only thinking this is related as when I re-installed then turned off the phone using a battery pull, that now the media gallery button will now not work at all, so that is a change.
Second, the power button is buggered. Seems unlikely as everthing feels normal, no big drops have occurred from heights, and the button is travelling in and out as usual.
I have also noticed that as soon as I re-insert a battery that the phone starts immediately, the M pops up as if it is already posting. So maybe it is stuck down?? Again, I don't think so, as the mechanism is working per usual.
If anyone can help it would be fantastic, you guys haven't let me down yet, and this thing is purring, but unfortunately I cannot use it lol. Just my luck.
Thanks in advance
another thing, still not solved
Another thing is happening, the phone screen turns on "after" pressing the power button, it may be once or a few times, and then pressing the gallery button.?!?!
Also, at random times it plays a podcast on my phone, the exact same podcast, and from the start, though the duration may be a few seconds then repeat, or it may go for ages, its quite a rude podcast too which has caused me to throw my phone under the car seat to shut it up when people have been trying to talk to me, as you can imagine its quite embarassing.
There are no services or apps running that I can find related to music, it may happen after pressing the camera button, or opening a website.
It is still going really fast though. And I have also reinstalled the light sensor program so I can turn it on and off without causing damage to the power button.
Thanks again everyone.

please clarify
sure, so the only way I can get the screen to turn back on, after turning off as per display power saving preferences, is by pressing the power button, maybe a couple of times, then following that up by pressing the gallery button next to the shutter button, pressing the gallery button doesn't seem to be working to turn the screen on now, but this combo is.
I hope that helped.
Cheers.
EDIT:::
The gallery button alone is working again. sorry guys.
You might just want to reflash it to stock to see if this resolves the problem.
Yeah I think I may have to.
Before I do., I was reading a post on a different forum where another person was having a similar issue. They seemed to solve the problem by using rom manager to boot to a manual restore menu where there was a button tester section, after using it the power button worked for them. I tried but after resetting it displayed a triangle graphic then rebooted.
Is there any way to do this with our open recovery program or any other utility to test the functionality or maybe reset the button or apply a patch etc.
Thanks again :-D

Getting Frustrating
Alright so I followed your advice on your videos on how to reflash to stock, so of course my bootloader does not show up the same as yours on the video. I can get to the bootloader fine, using the button combo or by using quick boot > bootloader, both have the exact same result, the boot loader screens as follows:
Bootloader Fastboot mode
80.89
and that is it....
Also, my computer using rsdlite does not acknowledge the phone, not omap drivers loading etc. Followed your instructions exactly.
This is frustrating me to no end lol.
I am guessing that because I can get to the bootloader with combo no problem, that the buttons physical connections are working.. At least thats a positive.
Can I flash to stock with openrecovery? Or maybe to an earlier version of Dexters froyo? Other ideas?
Any help would be much appreciated guys, trying to use this phone at work with light sensors to turn off screen is not as easy as they say. OMG....
Thanks so much

The fastboot bootloader isn't the right one. So... if you hold volume up + camera shutter while powering on you end up in fastboot? That's really weird.
Maybe your keys have been remapped somehow? Does anyone know a chord to boot fastboot? Perhaps check to see if your USB port is clean?
Lmao
Just my luck to have a weird problem. I thought it may have been remapped so I have been trying the program buttonremap. It doesn't seem to let me do anything except stop the buttons I re assign doing anything :'(
Does anyone have a proper key mapping file that I can replace with my faulty one to hopefully fix it?
Or any other ideas?
Cheers everyone

Ok installed anyunlock it allows you to use any physical button to unlock the screen. It doesn't respond when the Power button is pressed, it responded fine to volume rockers, gallery and shutter though.
Anyone know if this would mean for sure its a physical problem before I crack it open and try and fix it.
Thanks guys.

Breakthrough!
I am pretty sure I have fixed the problem, I tapped the phone fairly hard on its sides and back, and lo and behold after a battery pull and replacement it didn't turn itself on, I waited, nothing, so then I held the power button and it started up!!!!
But....I have another problem that happened before that, I am stuck in the boot animation that open recovery uses before going into its program (i.e. where you can load nandroid, wipe dalvik cache etc).
I was about to load a new rom, and was in open recovery, had installed it and about to do the reset and the phone turned itself off, and thats when I got the problem with the sticking boot animation.
So just to be clear, I am stuck in a boot loop, but not with the M logo, the restore logo.
I hope the power button solution can help someone else, as random as it is.
If anyone could help me get out of this boot loop without flashing stock that would be great. ( i can get to the real bootloader now btw)
Thanks again everyone.
Solved it all
Just took the sd card out and rebooted. And the power is getting better after banging it.
Thanks to all.

So, is your conclusion is that the button was stuck and the banging freed it? It doesn't restick?
The Button is not perfect still. Sometimes over sensitive Occasionally it will not even work but it works most of the time. I am just wondering what cleaning solution I could use to free it some more.
It has certainly been a trying problem. Cheers for the help.
Now I need to figure out why I have this strange ghosting on the top of my screen.....

Samsung Galaxy S2 Power Button Not Working
Hi Guys,
Any solution for the power button problem? Current latest Android 2.3.3 Samsung Galaxy S2 also having the same power button problem. Most of the time I can't use my power button to turn on/off the screen (wake/sleep) and there's no menu for long tap as well. Luckily it does wake when i press the only physical Samsung center button.
What i have already tried: Factory Reset, disable Power Saving Mode, Spare Part+ (apps), Screen Off and Lock (apps), and all won't help.
Is there any current updates or patches to allow the power button to work as usual?
Thank you.
take it to the samsung technical centre
Thats if you still have warranty

Power Button Issue

I have been having odd power button issues since updating to 2.3.4. It is almost like it is getting stuck or something.
Sometimes when I hit the power button to turn off the screen, the screen goes off for half a second then comes back on. This also happens when going from off to on (i.e. flicker on then back off), but it seems rarer.
Sometimes when I hit the home button (and just the home button), it takes a screenshot like I am hitting the button as well even though I am not.
All of this is fixed by just hitting the power button a few times.
Needless to say it is annoying. I thought it might be something mechanical, but I took the case off the back and the issue still occurred. It also seems like the button is clicking then unclicking (i.e. not getting stuck). I had no issues prior to updating to 2.3.4.
Anyone else had this happen or know a fix or workaround?
Yes! I have the same exact problem after the update!!
Glad to see I'm not the only one.
It's very annoying.
My backlight turns on by itself randomly and often if you press the power button to turn the screen off, it goes off then comes back on or flickers on and off. The power button doesnt always turn the screen back on either.
It also gets stuck where I press the home screen and it keeps taking pictures.
HTC better fix this!

I have the exact same problem too since upgrading! I have disabled the screenshot function in build.prop but that only stops the repeated screenshots part of the problem. The main problem with the power button still persists.
I'm having this too, its come and gone to different extents - pretty sure it was happening a bit before the update though.
I'm worried it is mechanical, I couldn't get it to happen with the back cover off but it could have just been coincidence. I can live with having to press the button again every so often but the screenshot thing annoys the hell out of me!
Since the update I've experienced an issue with my power button as well. Sometimes when I hit the button to turn the screen on, nothing happens. At first I thought it was just me but it happens at least a couple of times a day and never happened before the update.
I don't normally turn my screen off by pressing the power button so I can't report on that. Guess I should count my blessing that the screen shot function is not acting up.
Thanks for posting cause was beginning to think it was just me.
FIX!
I found a fix for this, in your build.prop remove the framework line for screen shots and then go in recovery and whipe cache partition twice as well as dalvic twice!
Cheers!

am I like the only one without this problem >.< lol. lucky me
I have this same problem too, I believe its connected to the screenshots but i don't know how to turn it off easily (how do I get into build prop?)
This is definitely after the update, I had absolutely no problems with the power button prior to the update.
I don't have any power button isues at all on my European Sensation (2.3.4 still S-On yet). Playing around it just for a week. But the Screenshot thing is a feature not a bug!
Just press <power button> + <Home> to take a screenshot. I like it.
I just starting having this issue yesterday too. Thought it was my power button getting stuck but good to see it's not a hardware problem and hopefully HTC fixes this.

I think you're right. As a test, I used AntTek App Manager to freeze "Scribble" which is also known as com.htc.mysketcher and I haven't had the issue yet. I believe this component is responsible for monitoring for the key combo for taking screenshots. Certainly, after freezing it, the Power+Home combo no longer works for taking screenshots.

I have just tried this but I still have the issue. Sometimes the power button won't wake up the screen and sometimes when I power off the screen it only stays off for a second and then lights up again.
I have this issue too, but I don't think it is software related problem.
It is, as the phone sometimes recognize a power button click as 2 clicks (screen goes off and on).
To see what I mean, go to Recovery and try to navigate through menus - when you're clicking power to enter any menu, sometimes you jump back, as if you were clicking "Go back"...
So, if the issue is even in Recovery mode, so it is not software related. I even restored my stock 2.3.3. soft and the issue is still there. I think it's a mechanical defect

The strange thing is, I even downgraded to 2.3.3 and I still have the problem. I have even flashed stock HBOOT and Recovery but the problem remains. I just don't understand it because it certainly wasn't happening before I upgraded.
Add one more person to the screenshot-club. Haven't had any other problems, but sometimes the phone just keeps taking screenshots when I'm pressing the home key. Extremely annoying, but luckily this is usually solved by tapping the power button. Ofc afterwards you have to clean your gallery of useless pictures... Argh!

[Q]Keys not working..help needed asap :(

Hello,I bought a HTC Desire S around 4 months ago.
From past 2 days i have lot of problems with it.
1.Home screen button not working
2.Q,A keys are not working while typing(they work when i rotate the screen)
3.Wen i rotate the screen and start typing the whole keys on the least bottom dont work.
4.Sometimes if i press back key it goes to selection option...sometimes whole phone hangs.
5.Im not able to download from market...after i click download it shows downlading icon but it never starts download.
I made factory reset for couple of times but no use.
Any one have some suggestions?
numbers 1 to 4 seem like some sort of problem with your touchscreen... Have you tried wiping it with some clean cloth after breathing on it? My back button has some issues registering touches once in a while, but wiping it helps always
Regarding 5, I don't know really, but have you tried using the webmarket?

Does the area where your Q and A keys are when in portrait work when the keyboard is not on? Can you use it to click items, scroll webpages etc?
One other thing you could try is the calibrate option for the keyboard. (somewhere in settings-> languages I think, it's been a while since I ran an Sense ROM).
If both yield no result, it sounds like a hardware issue to me, and you might be best of to invoke your warranty.
