Weird touchscreen issue.. - HD2 Android Q&A, Help & Troubleshooting and Genera

Hey guys, Im having this weird problem. I don't know if its software or hardware related.
I SOMETIMES loose touch functionality when I lock the screen using the "end" key.
What happens is, When I press the end key to wake it from sleep, the touch screen is not functioning. So I have to press the end key again to lock it and wake it up again to see if it works. Its a hit or miss. Sometimes I get it back sometimes I dont. I tried Resetting, Soft and Hard. Wiped the SD too.
This also happens in WM too. Any one know whats going on?
any input would be appreciated.

This thread addresses that issue

if you are using advantage task killer or autokiller, don't use "kill apps when screen off" or " start on boot"...

Auto killer isn't a kill app. It just sets androids natural kill ability a little more aggressive

Thanks guys but it seems to be a Hardware issue. At one point in an HD2's life the digitizer will give out.
Seems like the only thing I can do is try to replace the digitizer myself as I do not have warranty.
Thanks guys

This is happening to me too, thought it was just my HD2...

Moved you over to general were this non dev issue belongs

This happens to me only on Android not Windows.. tmo US hd2

Same thing happened to me. This is my thread explaining it:

unfortunately it is a hardware problem and your digitizer will completely die soon.
Mine is being done under warranty but if you will do it yourself these official teardown and repack videos will provide helpful:

Strangest touch screen loss problem! + SOD / QUICK WAKE UP TEST WITH YES/SEND KEY.

17/9/2010 EDIT: With a lot of feedback from this thread and other threads, it has come out that, waking up the phone with the YES/CALL/SEND green button is BETTER than waking up with the NO/END/POWER red button for SOD reasons.

Hello guys,
You probably know I am actively in the Android HD2 porting community.
I am having the strangest touch screen problem. I am really experienced into winmo and android stuff. Please read carefully.There is a surprise at the end.
BOTH under Android AND Winmo my touchscreen works just fine after bootup.
It first started like this:
At first my touchscreen stopped responding when I hold no button to make a reboot/power off. I thought it was from the usual Android touch screen freeze related to g sensor. Then I realized that it was the same in Winmo! Holding no button ALSO caused touch screen to die even under winmo.
Then it started loosing touch after sleeping. My touch is ALWAYS working when I boot winmo OR android and works for hours if not put to sleep. But it stops working after putting it to sleep.
Frustrated,
I restored with spb backup. Didn't work.
I reflashed my winmo rom. Didn't work.
I made a hard reset. Didn't work.
I removed sd card. Didn't work.
I removed sim card. Didn't work.
I changed the date. Didn't work. (this was a strange fix for some blackberries)
I flashed original 1.66 Turkish rom, 2.07 original old radio, even original 1.42 SPL which makes this hd2 fully stock the day I bought it. Even made another hard reset. Still didn't work!
By this time it's obvious this is a hardware problem and needs warranty.
OK
THEN I FOUND THE STRANGEST THING:
If I wake up the phone with ANY hard button other than the NO/HANGUP button touch screen WORKS!!! (Yes/Send button under Android)
BELIEVE ME, I HAVE TRIED FLASHING REFLASHING RESETTING AND TESTED 100 TIMES and YES it is ALWAYS the same. This is not a random thing.
If I wake up my phone with No button under ANDROID OR WINMO, my touch doesn't work. But if I wake up with back button windows button home button yes button, the phone wakes up properly AND touch works. Android of course doesn't work with the original radio, so I wasn't launching Android with the last test.
HOW IS THIS POSSIBLE AT ALL?? It looks like hardware fault, but touch loss IS related to NO button!
I will send my phone to warranty anyway but it will happen after the holiday (not before mid september)
IF ANYONE have an issue like this, PLEASE post.
I just want to make sure this issue isn't related to Android porting. If it is, this might be an important info. Maybe it may help devs fixing the general touch screen and wake up problems. Also everybody TRY waking up Android with the yes/send button to see if it helps with your wake up or sod issues and provide feedback. Also it may help with the phone not responding after hangup in Android. There is something hardware going at the background with the no/hangup button. I know this issue is hardware fault but still may shed light to our problems with touch screen and wake up issues. Maybe there is something hardware or firmware inside the phone waking up the digitizer. I know that hangup/no/end button is internally different than the other buttons, something like it shares the power button function that is usually on the top of the device with other htc devices. (Mine is a european hd2 and the hangup button is not red) I also wasn't using an overclocking kernel.
Please think twice before posting, and don't post anything useless. I am absolutely no noob, you can search my previous 200+ posts. I wouldn't post anything unless I am definitely sure. And I have a feeling that this thread has the potential to help or make something come out. If it doesn't, no harm done.
since most of the time inwinmo or android the no or yes button pop up generally on the same side in both os's and , taking in consideraton it might be a hardware issue , i would say you issue might be a harsware issue undr the screen when you touch no...wild guess
I was the same problem.... but it is even worst for me now...
Before, at least work touch others buttons... now my touchscreen DON'T WORK. :-(
I suppose that it's a hardware problem :-(

BIt strange this one to be honest I think it may just be your device as there are now hundreds of users of android on the hd2 and this is extremely rare. Hopefully a dev will look into and find a possible solution but I doubt it. If I was you I would put it back to stock and send it off to HTC for a new one. Even if a dev manages to find the problem you will have a new or as new hd2
I have been trying and I must say that I sort of do share your experience. The most left button (referred to as yes) awakes the phone just right as where the most left (No) takes its time to start the phone. I haven't had any noticable touch issues that could be related to these hard buttons yet.. (I think)
But I do think you have a point.
Interesting, I had something similar. I was using elegancia rom v1 for the longest time, with all my android builds, no problems. Then I went to chunkydroid rom, and had a few issues, with multiple android installs (one of which was my original that was working before.)
Then I rebooted into chunkydroid, (windows), and had the same issue. It was strange. I tried a few other roms, same problem. Turned off the phone, next day, reflashed chunky again, and hyperdroid 1.1, no issues since. (Only difference, which I don't know if it's related, but again, might help, is that I was overclocking. I have since not let anything go above 998 in setcpu, and even removed all builds that were overclocking. I though it might have had something to do with it (and the phone wasn't warm at all.)
I have not been able to duplicate the problem since though (even with overclocking just to see). So I'm pretty stumped. I'm sure the devs will work it out.
I have taken to pressing the yes/send key to wake up my phone as it seems more consistent than pressing the end key. My theory is that multiple wake up/sleep messages are being sent on the end key and the system gets confused. Some sort of debounce might help.
Just my thoughts.
Running shui8 realstock rmnet with micyprima r9.
It seems waking up the phone with the Yes/Send button somehow seems better with current builds and kernels.
I am asking everybody reading this thread to try waking up their Android devices with the yes/send key and share their experience if it is making their Android wake up quicker with less SODs.
Note: I am still using yes key wake up as a workaround for my hardware touchscreen fault. Still absolutely works everytime. I found out that if I accidentally try to wake up with the no/hangup key I need to wait about 10-15 seconds before yes/send key does its magic again.
well, i tried there is absolutely no difference between any hard button. if i have sod, none of them solves... actually its not sod i think, when you try to put standby and wake up several times quickly, screen stops responding for a while. you need to wait at least 15 seconds between each standby and wake up. can i fix this? or this is the sod?
Waking up with the yes/send button would not make any difference if your phone can wake up good with the no/hangup button already. But we are trying to find out if yes/send button wakes up better in long term usage. (no/hangup button sometimes can't wake up and that is the sod refers to)
SOD happened to me few times too with the NO/Hangup button and if/when that happens, if you press NO/Hangup button for long(for the menu with the turn off the phone,reboot,plane mode,...etc options) screen comes back BUT sometimes it locks the screen brightness to lowest possible setting(with %0 actually it doesn't completely turns off as you know).
Other than that "bug" NO/Hangup button works fine for me but as the OP, YES button is more stable and no SODs happen with the YES button...
Btw there is no difference for me YES button vs NO/Hangup button by means of quickness... Both works the same speed unless of course there is no SOD with the NO/Hangup button...
Just wanted to share my experience...
This thread is awesome
Thanks for this thread. I have been trying to use any android build for at least a full day with no success. Ive used different winmo roms and radios such as chucky and miri roms. I still ran into sod's. After waking with the yes/button i have had no sod issues since then, Once again awesommmmmmmme thread.
After some time my digitizer died almost completely. (Issue became worse) It is currently being handled under warranty. (digitizer is replaced)
But at least with a lot of feedback from this thread and other threads, it has come out that, waking up the phone with the YES/CALL/SEND green button is BETTER than waking up with the NO/END/POWER red button for SOD reasons.
any solution to this issue yet because i just started having this exact same problem w/ my HD2 yesterday before that it was perfectly normal and all the suddon the Power/END/NO button wake up cause the screen to not respond to the touch at all however wake up w/ home,back,menu,call button the touch screen works is back to normal
still can't figure out if its a hardware or software problem cause i also tried flashing bunch of roms/radios/and android roms as well and even went back to stock rom in hope for a solution
waking with green is about 2s faster for me.
Same thing happens to me before 2 days.I tried many hard resets,roms,radios and my screen didnt work.I couldnt even login in wm.
My screen was completely dead.The last thing i did,before my screen goes unresponsive was to push no/hangup button in android to open it
At first also i thought it was a g-sensor issue,but then realise that it was much more than it.
Until the moment i read this thread
The way it worked for me
I open the device with no button of course,made a soft reset from red hole and i wait until the device goes to standy itself.Then i open it from send button and voila touch is back !!!!
Strange thing but it works.Thank you very much you are a genius
sure the touch comes back when it wakes up using all other buttons except the power/end button so why is that all the sudden the power/end button causes the screen to go unresponsive
like for say when i hold the power/end key to open the pHONES OPTIONS in windows or android once the PHONES OPTIONS shows up and i try to click on power off or reboot on the screen the touch doesn't respond so the only way to reset or power off the device completely is the either use the reset button in the back or pull the battery out
i'm going to be sending it under warrenty/insurance to t-mobile and hopefully get a replacement cause i'm so use to the power/end button to wake up my device...
Guys be extremely carefull when using hard buttons in android.Finally my problem with screen is not the end button but the back arrow button.This button is necessary for using android and i have pushed it many many times the last months as i am using android.Νοw every time i pushed it my touchscreen stops responding.Τhe last time i pushed it my screen stopped responding(i thought for ever) and didnt knew the exactly reason that this happens.Because i didnt want to send the device to htc (firstly i must send it to expansys in france and they will send it to htc) and take it back at christmas i decided to go to a local mobile service.I wasnot mind for warranty cause i wouldnt be able to live 4 weeks without hd2.I was ready to give 600euros to buy desire hd
Result from service
At firstly he said to me that hd2 have no touchscreen problem and it works ok
I paid 20euros for opening the device and took it back.At first 5 minutes my screen stopped responding again and didnt knew the reason.For my good luck i leave the device untouched 10 minutes and the screen come back again.Then i used it and the time i pushed the back button the screen stopped working,fortunatelly for little seconds.Now i know.My screen stop responding when i push back button.So i change the keylayout to my android build and now i push send key instead of back and volume up key for menu and volume down for power on-off and hd2 works perfect after 24 hours without touching the back button
Also in monday i will go to service again to fix the button problem
Same issue with me
Exactly same issue with me. I have been using Winmo and Android on and off in my HD2. couple of weeks back, touch didnt respond after waking up the device from standby by pushing endkey.
tried everything - flash/stock rom/removed SD card/ hard reset/clear storage/custom rom/ battery pull out etc...
touch worked suddenly and only when i slightly touch the end key instead of pushing it fully, the start menu opened..this happened for few days and when ever i push the end key...screen goes unresponsive. all other hardware buttons are working fine and if at all i push end key the issue starts.
unfortunately my friend pushed the end key once and the screen never responded after this....now am using my old p3450 htc touch...
i think if we change the AP BOARD (Flex ribbon-keyboard chip) everything will go back to normal coz its not the problem with digitizer or the lcd of the software for sure.
trying to order one in ebay, we can change this ourselves...no need to send it to service centers and waste money on it.
if any of you have done this already...let me know if it worked for you.
guys dont know if it is allready known but there is a app called sidebar style swkey

HD2 New Weird Screen wont unlock issue - help

this is a new problem for me. I have been using the most recent Dutty ROM together with Mdeejay Android ROM without any problems. All of a sudden, when I try to unlock the screen after STANDBY, it just wont register my touch, as if I am not touching it. It boots up fine, and on the first unlock works fine, but when the screen lock goes on again (after every standby) it just wont unlock. So I am stuck (I use Exchange and our policy forces the lock after standby, so I have to use it - and its worked fine for ages).
If I boot into Android, it works fine, the unlock works fine, yet strangely when I try to shut the power down, THAT screen also doesnt register me touching it.
I have hard reset but even before I load an app or do anything, the problem exists.
I also reflashed a DUTTY ROM. Same problem.
I tried CHT lockscreen - same issue. After Standby, screen doesnt register my touch.
Anyone have any ideas?
Same problem for me.. Restoring a backup image after being forced to hard reset this morning and now suddenly my HD2 won't wake up after sleeping. Pressing my end key only lights up my buttons but I have to pull the battery to reset. I'm thinking it's related to me having CHT installed, yours however might be a different problem.
I had something similar. It was right after I had installed CHT 2.0 and was looking to make the top and bottom bars transparent. I found a cab that claimed it would do this and installed it. Sorry, I don't recall what cab it was and I have deleted it. When I rebooted Sense would hang and if it got into a lock it would only move the slider a little where it would stop. Luckily, I had done a backup that morning right after I installed CHT 2.0 with Sprite so I restored and all was well.
I don't know if this is of help but I figured I'd throw it out there.
it wakes up, but wont register when I try to swype the unlock screen.

Your lucky you get that far lol.. I don't get any waking up. Plus I now uninstalled S2U2 and still no change. Disabled all locks of any kind and still frozen with sleep of death with in 1 min of hitting power to sleep it. I REALLY don't want to to a hard reset and install everything from scatch.. UGH.
weird update...
It has something to do with which key i witch the device on with. If I use the phone key, I can swype the unlock. If I use the power key, it doesnt register.
Another related issue: when i hold the power key to switch off, it wont register me touching power off or reboot etc. so I have to take the battery out to switch off. Its the same in Android.
Anyone know? Hardware issue?

im having the exact same issue. I have flashed 3 different roms and flashed to the newest radio (2.15).

SOMEONE PLEASE HELP!!!!
It's a quite common digitizer problem lately... it seems the HD2's digitizer is failing on some units, possibly because of usage with android? my father's device acted the same way, only it sometimes did register touch and other times, not.
My device doesn't have these problems, yet. But seeing that a lot of people here are experiencing these issues, and with the notion that I use android pretty much all the time since I first booted my device, i'm pretty sure i'll experience it soon as well..
Make no confusion thou, the assumption that android effects the digitizer are purely my own thoughts on this matter, no such thing has been proven and the conclusion that android is effecting our HD2s is based purely on the statistics of touch screen failures in the last few months since android has been made publicly available in a working form.
EDIT:
Those seeking A solution, as far as I know, the only solution is sending your unit to HTC for repairs, you'll get it back with a note that says that they replaced your digitizer or your screen, at least these are the reports I heard from the other folks whom followed this procedure.
Good luck.
HTC HD2 Screen Lock
I have only used Android a few times on this 'phone and it has a standard HTC/O2 ROM installed so it must just be a problem with the top part of the digitiser. With android running the unlock is at the bottom and is unaffected.
Is there any way of testing the digitiser before deciding whether to get a repair sorted,

A friend was complaining to me about something like this since last week. I could not figure it out so I went ahead and installed Android cm7 and still have the same issue.
Until I read this post after searching through the forums all over Screen now unlocks perfectly fine but only using the green Phone icon. If I try to wake the screen with the red Power button, the screen is unresponsive.
Thanks for the info.
Already happened tome its a hardware issue can't be fixed so if you still have warranty on ur phone send it to htc for repairs b because it tends to get worse n worse soon other keys will start to give in I think that's one reason why most android phone been switching to capacitive buttons because hardware causes this sorta issues and send it in for repairs to get it fixed

[Q] Replacing Touch Digitizer fix NonResponsive Screen?

Hey everyone my HTC HD2 got the Non-Responsive screen problem a week ago, & did a lot of research and found out that it was most likely a hardware problem with a cable..... So a lot of people would tell the people with the problem that the "Touch Screen Digitizer" is dead (like the cable), or it needs to be cleaned... pretty well go out and buy a new one... BUT I have never found evidence that someone has done this and it has successfully "cured" their HTC HD2 Non-Responsive touch screen problem...
So I was looking for anyone on the forums that could confirm this is a solution or give me any tips on what I should do.... AND no I don't have enough money to get a new phone, nor do I live in the USA so I can't send it in to fix it...
This is what I was going to buy for it:
http://www.ebay.ca/itm/NEW-OEM-HTC-H...item519a3d2e45
Thanks for taking the time to read my Thread, its much appreciated!! I hope I can find a fix!!
PS: If anyone wanted to know what it looks like out of curiosity I posted 3 pictures with RED circle HIGHLIGHTING the problem when I try to touch something....
I really want to know this as well, because my phone is basically unusable at this state. I can get into it maybe 2 or 3 times a day, if i really try (locking and waking up the screen over and over until it becomes responsive). I don't want to buy a new digitizer if it isn't going to fix it, but i would gladly buy one if it will fix it. If you try it, and it does work for you, send me an email at [email protected] .
Anyone with any other information on this please help us out, there is a surprisingly small amount of info on this issue, considering how many phones were affected.
screen
I have read some threads on the power button being the cause. Try pressing it several times. Once you get the screen operating go to the market and get screen off app and a reboot app. Place them on your home screen toolbar. I use adw and it has an extra hidden toolbar if you swype down and then up on toolbar and up then down to close it. Either way you do it is fine. This keeps you from pushing the power button which has been discovered to be the problem. Hope this helps. I haven't had the problem, but seeing that it's happening more often I use these apps to keep from using power button unless needed to boot into magdlr.

Thanks for the help, yeah I havee seen that problem and I think that is my problem as well.... I am going to get a T5 Torx Screwdriver am pop open to see if I can maybe fiddle with the cable to get it to work again.... if it doesn't i might get a new digitizer or just have to go back to my old phone and save some money for a new smart phone

HD2 Black screen after a call?

Is there a fix for this? No matter what rom I use, Didn't try Froyo, but after receiving a call, the screen stays black, so I spam the hard keys to wake the screen after about a minute or so. Can anyone help?

I have the same problem with 2 HD2 phones. Not aways, but most of the time. I ask this question before - http://forum.xda-developers.com/showthread.php?t=1349809 , but i didn't get the answer.
May be it is hardware problem, but if it is it's gonna make me a problems every time.

Once in a while i have the same problem, but when I clean the screen (until it looks shiny ) and it gets better…
(I clean mostly the top of the screen)
I don’t believe it is the “solution” but works for me…

If you push the End button (or any other button) before clean the screen, what happens. Does the screen stays black???
I think that this is a software problem, because other ways every time when I press the End button (or any other button) it will give me Nothing.

Is there a fix for this? No matter what rom I use, Didn't try Froyo, but after receiving a call, the screen stays black, so I spam the hard keys to wake the screen after about a minute or so. Can anyone help?

I have the exact same problem. I am using the SD card android version. I've tried different ROMs, but with all I have this problem. When I boot into WinMo I don't have this problem at all, so it doesn't seem to be hardware related.
I can use the phone with anything else without any problem using the SD android version, only when I recieve a call or call out myself the screen blacks out and the phone seems unresponsive. After about 30 seconds to a minute the phone shows the lock screen.
I would love to work with the Android version for normal operation but because of this I still boot into Winmo within office hours...

Your better off doing what I did. In Android, sonewhere in the settings for calling, change the sensor to off so it never blacks out. In Miui rom its in program's, then calls.

Task 29 and start fresh. Only thing that got rid of it, test when you first start the rom to make sure it works normal, then start adding your apps and such.
Or increase the 125mhz CPU settings to 245mhz under cyanogenmod settings/performance/CPU or governor settings.

my screen stay black (off) when i take the phone away from my face EVERY call as well. this is what i do and it works everytime.
1.)pull the phone away from my face (duh)
2.)starting with it facing the sky, i turn it to face the floor (when i say facing i mean screen up ... then screen down)
3.)as soon as i turn it back over (screen face up) it turns on
im thinking its a sensor issue??? either way it works and i dont go on a hardware button mash fest to turn my precious leo back on.
if this helps please send thanks ... if not tell me im crazy :-D

I just download this apk and will try it ....
But I think it's hardware problem (may be with the sensor), because when I turn back on Win Mobile 6.5 i have the same problen ...
I think to bring the phone to service
... when I take it back will tell you what is exactly the problem ...
Task 29 then install windows, next install the right radio version , finally install the android
like dragonovus say´s try completly reinstalling android.
and please feedback here
BUILD.PROP baby!!! there is a tweak for this and i believe it works( in the prop ) dont know exact address but google "build prop tweaks" also use setCPU and set the lower number to about 350+ also try to use the end hardware button less cuz this has been addressed in another thread..... the button sticks or sum crap..... i use zmooth and never use the red end button........... good luck
Will try all, but now I use ' Screen stays on '

well ... for me Screebl Lite didn't help me
Reinstalling Windows is not necessary. Just make sure you have the right Radio and HSPL then do a task 29 before installing Android. But your problem is most likely hardware related. The end call button is most used and therefore prown the wear and tear... Try using the red end cal softbutton. I guess you only have that problem when you use the hardware button right?
In that case it's the problem with the button and not the software...
And at the end did anyone of u solved this? If u need help post reply or pm me. I think i have a solution for u.

Yes, man! I have the HSPL2.08 and radio 2.15.50.14 ... I think we all do. I can't use the soft buttons, because I can't see them. That's is the problem. The screen is black and won't lights up. May be I can't read you ... but I try to run back Win Mobile just to check is it from android OS or the sensor...
build.prop does not help
I tried the build.prop thing. I added those 2 lines at the end of the file:
ro.lge.proximity.delay=25
mot.proximity.delay=25
No change, still a black screen after any call.
Any other idea ? How to completely deactivate the proximity sensor ?
Fixed !
I finally fixed the issue by removing the screen protector sheet and cleaning the upper left part of the screen with a dry towel.
It works fine now. It was just a problem of the proximity sensor not being exposed enough.
I hope this helps.

Help! Cannot unlock screen, touch function not working.

Has anyone of you guys encountered the same issue with your HTC HD2? Care to share the fix you did? Would this mean bye-bye to my HD2 already?

If a clean install (task 29) doesn't help, then I guess you have no other option than sending it for reparation.
It seems like there is a limited life span on the touchscreen. Mine died in October, and I had to buy a replacement because nothing I did fixed the problem.
I had the same issue as you, but in my example touchscreen is slowly dying. For example I can't wake up the phone pressing right (red) button. So I learned that using any other button will not cause freeze of screen. I also discovered that if you gently slap your phone on hand, magically screen starts responding. Weird, but it's ‘working’ like this since 5 months so far.
I just encountered this problem with my HD2 as well. It seems that this is a fairly common issue. Apparently the digitizer for the touchscreen is located directly beneath the red power button and has a tendency to lose its connection.
For me, holding the red power button down with some force for about 5 seconds fixed the issue. Is this temporary? Perhaps, but it has worked just fine for a few days now. Try that out.
Can't Unlock the Phone..
I am having the same problem..I can't unlock the phone..No matter what android Rom I installed.I tried to removed the lock screen and the touch stopped working..But when the phone restarts and you put you pin etc,I can use the phone normally..but when it goes black and trying to turn it on again nothing works on the screen..
Though the hard buttom works..Home screen etc..but can't get the touch to work after the screen goes black!
It's not rom related
I have installed WM6.5 (Stock), Android GB, Android ICS, Android JB But the problem appears to be the same in all
when I press Red button touch doesn't work any more
I would go with digitizer theory
BUT my question is this:
is it gonna get worse? cause for now as long as i avoid Red button everything is OK :good:
and I love my HD2 but if getting worse is possible I have to get rid of it :crying:
Well i had the same problem.now my phone has been to the service centre for reparing

Funny (or sad) thing is we don't have an official service center here
so only option is to replace it or sell it as the way it is
Try this:
Lock the screen normally, screen turns off. (Power button)
To turn it on again by pressing any other screen buttons other than the power button. (DONT USE THE POWER BUTTON TO DO THIS)
I found that if I do it this way, the screen runs normal.
