V1605 Problem with screen - Phantom Tap

I have had this phone for just over a month now. Everything has been working perfect except for the last 2 days.
What is happening is that there seems to be a "phantom" tap on the screen in the right upper corner (device facing you - under the small camera) resulting in
A, Phone always going to today screen, so programs keep closing by themselves as the X button is being pressed by the "Phantom" tap
B, In the top right corner (as described above) if one looks closely there is the animation of the circle with little white balls - the same on gets when one taps and hold the stylus before the menu pops up.
When this starts happening the phone is unusable as everything that is opened is closed by itself. At time the screen locks also and it does not respond to the stylus.
Strangely enough this tends to happen during the hot periods of the day and when the phone has been used for some time. Then if i remove battery let phone off for some time and restart it everything is back to normal for a couple of hours but then problem recurs.
I did a hard reset as to exclude any application that could cause this and the problem still persisted.
Apart from this screen alignment works perfect - no issues with that
The serial number of my phone is HT648F######
Rom Version - 1.20.161.6
Rom Date - 08/02/06
Radio Version - 1.03.06.00
Anyone had a similar problem please
Any help and suggestion are greatly appreciated

Touch Response Problem

I have a Sprint Touch [Vogue]. It has served me very well up until recently.
One day, I was using my phone normally when the battery died. No big deal right?
Well, I charge my phone and reboot it. For some reason, Windows is EXTREMELY slow and unresponsive. I figure that something vital had been corrupted by the battery's death, and that it was nothing that a hard reset couldn't fix.
I performed a hard reset.
I let the utilities for the first boot run to customize the phone. Everything seemed pretty much normal. I configured my settings, re-added my contacts, etc. Then I turned the screen off [with the power button].
I turn it back on later to do something. I touch the screen. It immediately and accurately detects the touch's location, but it continues detecting a touch. For 20-30 seconds, after the input has stopped.
It was strange, so I soft reset the device. It booted, with the same problem. So I performed another hard reset. I did some configuration [the response acting normal at this point], and then turned the screen off. Turning it back on brought the same problem back.
This problem still exists on my phone, even after numerous hard resets and even ROM flashes.
A better description of the problem: When the device is first turned back on [meaning brought out of standby], its touch response is messed up. It will immediately and accurately detect any touch input, but it will continue to detect the input for up to 30 seconds AFTER it has been released, as if you were holding it the whole time.
WHY is this???? My phone is almost unusable because of this!!!! I can still place/ receive calls, using the navigation buttons and the red and green buttons. But the touch response is screwed!
Can someone please shed some light on this problem I'm having?
Phone specs: Windows Mobile 6.1, HTC / Sprint customized. Minimal third party software is currently installed.
[I've already determined that third party software is not the problem, because i haven't installed any!]

Possible solution
Hi,
today I experienced something similar to your description - no touch response when I tried to pickup a call. The strange thing is that last night everything was working and no settings were modified nor programs were added/removed. The screen suddenly 'died'. At the moment I am using it through a program MyMobiler which brings the mobile display to the PC and I can use the mouse to control the phone (it is like VNC for the phone screen, the phone is connected with ActiveSync).
This is temporary solution untill I finish my backups of files, programs, settings. I didnot performed hard reset yet, hope this will solve my problem
In the following link there is a 'magical' solution - to remove the screen protector:
http://www.htcwiki.com/thread/1112981/LCD+or+Touch+screen+not+working
P.S. I had removed the screen protector and voilá - the screen is now touch responsive. The root cause of the problem obviously is the dust between the screen and the protector which results in constant screen pressing - and as a result no accepting my finger presses.
I hope this will work for you and others with similar problem.

I had a similar experience with an old Vogue.....In my case, there was no battery death precursor, but it just started acting up. Not too long thereafter, I noticed the screen/digitizer was forming what looked like an air bubble between the digitizer and the LCD on one place of the screen. The screen was becoming defective. I eventually had to buy another Vogue from a friend who didn't have a clue of the 6900's potential, and didn't want his anymore, so I got it cheap.
Sounds like your screen/digitizer may be on it's last leg.

[Q] Touch screen intermittently wont work from lock screen.

I have the WP7 installed. No dual boot.
I have a password protected lock screen, and every once in awhile, the touch screen wont work, so I can't slide up and put in the password. If I hit the windows button in the middle, it kinda bounces for a second, then goes dark again.
It happened yesterday too, and the only way I fixed it was to turn it off, take out the battery and then turn it back on again.
When the touch screen works, it works fine. It's perplexing.
Anyone else have this problem?

Yes, but I only have to tap on the screen and the touch screen is working again and I can slide up the screen. Had this happen with both of the builds I've used so far.

This didn't work for me. My phone's been locked all night.

Hmm, not really sure what it could be. Check with whoever built the rom you are using, they may have a better solution. Sorry I couldn't help more.

Its a hardware problem, not software, i had the same problem the solution is to change touch screen, try to press touch near red button for same time it can help, but not for long time.
Sorry for me english)

Common problem. Your touch screen is fried (or is in the processing of frying). Start the warranty process now.

fried? dunno mate, when my touch screen goes on the blink i sweep a finger in the opersite direction to what i usually do then try again straight after, so forinstance, at the lock screen i try up and it doesnt work, so i try down then up and that usually fixes it, same for the tile screen, if it wont work as i sweepleft, i sweep right then left.
this doesnt happn on android which i would think rules out an overall hardware fault, at least for me anyway, it is however hardware related, the HD2 shouldnt have WP7, the drivers are not designed for our device so expect these odd happenings.
Of course its equally likely that this could be another sign of the pain in the arse SD card issues some of us suffer, reflash and try a new SD card and see what happens.

Man its realy problem of touch screen because it breaks in zone of red button, and when you press it some times it goes ok, and works wery well, but it die from now, replace the touch or it will die in few - weeks- days.

i would seriously get that accusation backed up by some proof before someone does something they didnt need to do.
I have random unresponsive screen issues that are directly related to the install of WP7 it does not happen on android or WM, there for its not hardware, at least in my case, its driver

[Q] LE E900 Unbranded AT&T USA touchscreen NOT responding! PLEASE HELP!!

I really like my LG E900 phone. I bought it for AT&T in the USA unlocked on Amazon. Installed Mango recently with all the firmware upodates and until today been having a lot of fun with my phone!
All of a sudden today, the touch screen seems un-responsive. The touch screen works intermitently. It starts to work then stops again. I have tried resetting the phone (have to pull battery). I wasn't doing anything when I this happended. I recently installed Tango and Livestrong mobile app, otherwise phone was flawless.
1. Is my touch screen broken?
2. Does anyone have a clue. I thought maybe the phone is running apps in backround but I can't seem to find the problem. The battery seems to drain also.
3. The phone does become operation for minutes at a time but then goes bad.
I wanted to add that the screen is also very slow at first then starts to respond normally. Almost seems to something happening in the backround. As of now, the screen is still not responding. If I continue to play with the screen, sometimes the screen starts to respond, but slowly.
thanks for help!!

In your position, I would try to:
1. Use the guaranty (if it's still active) and take it to a local service
2. Flash a different rom/firmware with all the latest updates inside and see what happens.
3. Buy a new e900...they cost less than ever nowadays...(almost 180€-190€ without a contract...)

You have got to be kidding me, the exact same thing is happening to me, and for 2 days now. I'm unbranded (I believe) on Vodafone Spain. The entire phone has become unresponsive. Drops nearly every call, has rebooted about 50 times in the last 24h.
fUnny thing is, it doesn't ever reboot when I'm actively using it, just during lock screen.
cOuld you further develop your symptoms just in case we have the same issue? Thnx

More Detail about the LG E900 WP7 Lock Screen issue
OK. SO here are the symptoms-
- Whenever I enter the lock screen, the touch is screen does not respond. TO be clear the touch screen senses I am touching the screen but the lock screen doesn't move when swipe.
Ater some research you can find the SAME EXACT error on HTC Surrround Samsung Focus. here's the youtube video. exactly as it appears except time to unlock takes about 2:30 (2 minutes 30 seconds) on my LG
http://www.youtube.com/watch?v=t3QABdcTINc
So here is what happens and what I do
1. Again entering the lock screen, and attempting to unlock the touch doesn't reposnd to any swipes.
2. You continue to swipe and occasionaly hit the physical buttons. This keeps the lock screen on. You have to keep swiping for about 2:30. After 2:30, the touch screen just seems to respond.
3. After the touch screen responds. Nothing out of the ordinary. When I tried using IE, it seemed that IE didn't work as well. Pinch to zoom, swipes not as good. Also portions of the screen are not as responsive.
So maybe start looking for a replacement.
I've tried
- restoring previous OS and files. No change.
- Hard and factory reset. No change.
- changing the brightness setting (AUTO, low) no change
The only thing that I haven't done is upgrade/downgrade the firmware. I think that may help but not clear on what to do.

Are you using the correct charger?
I have an HP Touchpad that has a high output microUSB charger for rapid charging of the Touchpad's battery. Although it hasn't (yet?) given my e900h any troubles, I did read at least one report of a guy's Samsung phone reacting poorly with symptoms similar to yours after using the Touchpad's higher output charger.

I am using a third party USB charger. Not a high power one, but an inexpensive one from monoprice. Ok, I will try.

Some people have reported errors and crazy system behavior when using third party chargers...

Still no luck. Using stock charger now. Will wait to see if any improvements. Thanks everyone.

I was one of them. This behaviour would occur with the charger connected.
I get the feeling the problem the OP and I are facing is also related to chargers, but no longer when they are connected. Charging makes no difference for me, the phone is still reacting very strange.

More Info on failiong touch screen
So
Here are more precise deets
- Whenever the backlight is turned off, the touch screen becomes non-responsive
- The touch screen notices touch but not swiping.
- in order to get the touch screen to respond you must continue touch the screen for 00:02:30 (2 minutes, 3 sec).
- the touch screen will usuallly start to respond to swipes but only a single axis (e.g. vertical or horizontal)
- after 2:30 the touch screen responds like everything is ok.
- the goal is to make sure the screen backlight stays on until the for 2:30. In some lock screen cases, you can issue a voice command, camera etc which effectly keeps the phone one (i.e backlight on) for longer without having to continuously touch.
- issues came after tangoi install and livestrong install.
- wonder if tango did something to lock screen
- also tried changing lock screen wallpaper - no changes
- when installing microsoft insider app, I tried using the wallpapers, but the apps crashes. Changing wall paper using default app works
- using default charger no changes
- received the latest update (fixed voicemail and outlook issues) - no change
I haven't been able to retore/flash NODO. That is probably what I need to do.

same problem here, new phone, original recharger and touchscreen of my optimus goes sometimes frenzy...the frequency of strange behavior raises when I fully recharge battery
i found a video on youtube, but yet i cannot send urls, because i'm new user here, u can find it if u search "problema telefono"
any1 have some solution, pls? or did u try to send the phone back to LG service?

Unusual touch screen issue - delayed on start up?

My LG Optimus 7 touchscreen stopped to response with no reason. Nothing was installed or damaged - one minute I called and after turn off and on it stopped to respond. Well - not really stopped but respond in strange way not allowing me to unlock (swipe) lock screen:
http://www.youtube.com/watch?v=QOb54qugw-A
(I took this video after Factory Reset which did not help - that's why it's in German)
And even if I reboot it, no buttons tapping is working, nothing - only this strange unlock screen which moves really slowly and not allowing to unlock.
I ordered and replaced digitiser (dismounted all telephone myself) and this did not help at all.
But I realised yesterday that if I leave my LG with screen open for 2-3 minutes IT STARTS WORKING!! It reacts on touch as it was before! No idea why and how. Unfortunately it goes into unresponsive mode after turning screen off and on, and I have to wait again. So it's useless...
I tried to google and I found few other people experiencing the same issue with different telephones (or tablets). Does it mean it's hardware issue? Is there any point to downgrage ROM - at the moment it's 7.10.8862.144??
