Touchscreen Unresponsive After Sleep

Anyone else have this problem? Sometimes, if the screen goes to sleep, when I wake it back up, the touchscreen is unresponsive. I have to soft reset to get it to start up again. Any ideas on how to fix it?

I had the same problem, and flashed another rom, and problem gone.

Hello guys,
I was just searching through the forum with this exact problem and found this thread.
If the phone wakes up from sleep the touchscreen is unresponsive for a few seconds. If I insist to press it it only takes longer for it to respond. This is a very big problem because I sometimes miss calls because I can't answer them. Not even the for hard buttons don't work (maybe because they are also touchscreen).
I've tried flashing different ROM's (Miri, Dutty, NRG) even flashed back to the standard one and again back to a 6.5 one (as I saw this step fixes a lot of problems for some people) but the result is the same. I'm running out of ideas.
I don't think it's a hardware issue because if i leave the phone until the backlight dims and touch it, it goes back on, so it registers the press but doesn't act on it.
It's a very serious and I'm hoping someone here has a solution.

Nobody else is having this issue? Is there no hint on what is going wrong with our phones?
It appears it's happening more and more often and the screen is dead for more and more time.

Hi
I have had the same problem but solved tonight
There are many threads about this but no real solution I tried them all.
My first HD lasted till last week when I had to replace it because of a "Newton Ring" problem. In 10 months of ownership I got a screen freeze maybe 5 times.
My new replacement arrived last Saturday - same original Orange Rom and radio.
I have loaded exactly the same programs from the old phone and have found that when I put it in sleep mode via the power button its a 50/50 chance of it waking up. Receiving a text message does not wake it up either.
I can hear the volume control working and the haptic buttons provide feedback - but black screen. If I hold the power button down I get the bleep to ask if I want to power the device off - then all goes dead. If I wait 5 minutes the haptic buttons/volume buttons work again and the screen comes alive revealing the yes/no option to power off.
Also strange whilst in this locked state the orange charging light comes on - when it goes off I know i can wake the screen up !
I tried :
Enabling and disabling the Today Screen timeout
Auto adjust backlight off and on
Different screen brightness
Manual/default operator selection
Checked HD Tweaks settings were correct in registry and things I can't remember.
What has worked :
Start - Settings - System - Power - Advanced and unchecked the box "turn off device if not used for 5 minutes"
The daft thing is this was enabled on my old phone and would always wake up with a text/call or power button push !
What has changed ?

Update - Found the problem
Whilst the above fixed my freeze problem it has been bugging me why - as the advanced power features are useful and I don't always remember to hit the power button to sleep the device.
I have now realized what was not set up the same as my old phone.
No start up password !
To enable this I found this thread http://forum.xda-developers.com/showthread.php?p=5004821 and changed my registry setting to 0.
This immediately takes you to the lock screen where you can now enter your password details and make them stick.
I now have a start up password and can set the timeout to 24hrs.
All the power settings now work correctly - and no screen freeze

Spoke too soon
3 hours ago went to use my phone - black screen
Connected via activesync and MyMobileR.
Rebooted and got the "Microp Version Mismatch 0" message.
Checked out threads about this error on the mainly Diamond forum and can confirm my screen is well and truly dead.
Contacted Orange and they are sending another replacement tomorrow.
What p*sses me off is the number of hours I have spent to get one normal days use.

Sorry to keep posting to this thread - but I am hoping that my experiences may help somebody
As said I am getting a replacement tomorrow and in one of the threads a guy said put it in the fridge for 20 minutes !
Well I thought what the h*ll and did.
Wrapped it in some tissues to absorb the condensation when I took it out - replaced the battery and it works - no Microp message and has behaved ok for 6 hours.
Got to be a hardware issue ?
Your thoughts.............

http://www.fixya.com/support/t982721...not_responding .

Hi
Sorry your link is not working.
As to the phone it was still ok 26 hours later when I had to exchange it for my replacement.
Weird !

Hi Andrew,
the fridge trick did not work for me. i kept searching for solutions and i found out that the problem is the digitizer (the touch screen). it might have received a shock (dropped on the ground) or other unusual pressure (in the pocket), and the digitizer gets out of initial position. the digitizer takes that contact as a tap -a continious tap- and does not respond to other taps. you might have to open the device and reposition the digitizer or replace it is there is some damage.
cheers
mumur

Sorry to hear that.
My replacement phone - so far has behaved perfectly.

Andrew

it strikes me that if I shake the phone that the phone jamming. I get no response. Even when I tap my finger hard against the rear top I get a crash. The only solution is to take out the battery and reboot. I think it has to do with a hardware problem.
there are others who also suffer from it?

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] 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?

[Q] HD2 becoming unresponsive to touch

The problem began randomly while using CM7 Barebone. Upon boot, the phone works as usual. However, it would stop responding to my touch when I would try to slide the unlock screen. I would have to turn the screen on and off a couple of times and finally it would respond again.
I assumed it was a ROM issue, so I switched over to Paranoid Android, however the problem is happening on this ROM as well. Initially, I assumed it was a hardware issue, but the phone works perfectly fine right after I boot it back up.
Does anyone have some idea as to what could possibly be happening? I'm worried that this will just get worse and I'll end up having to purchase a new phone.

Search for unresponsive screen, your issue is likely to do with the digitizer. When you Held down the power button to reboot the phone this temporarily fixed it (it's a known temporary fix). Install some sort of lock screen widget so that you don't have to use the end call button too much, and unlock using any of the other hardware buttons.

Touch stop working after turning off and on the screen.

I've been using the PH-1 for a year and a half and its great, but a couple days ago i would unlock the phone via fingerprint (as ussual), it would unlock but the touch wont work, so i factory reset the phone and still the same, remove the case and the screen was loose (almost complete), but the cable was well connected on both sides so i got the screen glued, but still the same.
Im using Android Pie (from day 1) with March update (updated like a week ago), in order to use the phone beyond what Google assistant can do i have to reboot the phone (using power and volume buttons) to get the touch to work again and dont let the screen go off. Sometimes after rebooting the touch works even if i turn the screen off and on, but i think its just luck.
You guys think it might be a software issue? or hardware issue? because i don't live in the US or CA, so i would have to wait a couple weeks for the screen to get here and i would'nt be able to return it in case its not a screen malfunction.
I really don't wanna change my phone, i love the PH-1.
EDIT: i just replaced the screen with a new one from fixez.com and the problem persists, i think april's update broke something. is there something i can do to check the software? Pls help.

I rooted my phone and almost the same thing happens. I turn off the screen and turn it back on and the touch is unresponsive. Howver, ONLY the apps left on screen are unresponsive. I can still pull down from status bar its weird.
Update 1: I saw u mention fingerprinting. I removed mine and somehow it seems to have stopped. I'll use it for about another day or 2.
Update2: Well it doesn't. If my screen times out with an app open. The app is unresponsive upon waking.
