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
http://forum.xda-developers.com/showthread.php?p=9726110#post9726110 which puts software buttons in the screen.This app is definitely button saver

[solved] bootloader dont load

wanted to install wp7 with a clean start...so tried to task29 (doloop) with 100% success and then my tmo hd2 wont go into bootscreen what ever i do...its stuck for ever in "stick together"...i know there is no os to load...but i dont understand y cant my hd2 go intobootloader
so far i tried
with holding volume down and power key with a single tap
with holding volume down and holding power key
with holding volume down, volume up and power key with a single tap
with holding volume down and reset button
with/without sim
with/without SD
with/without plug in wall charger
with/without plug to pc via usb cable
observations...when i pull out the battery and put it back in and then connect to computer when the phone is still off....the charging indicator LED glows in orange.
when in this mode if i switch the phone on with power/end key....it doent start...i have to pull the usb out, the orange LED still glows...and if i tap the power/end key nothing happenes...i have to pullout the battery to get it to start and eventually get stuck in "stick together"..
would really appriciate if any1 can help me get my hd2 into bootloader screen...

resolved the problem myself.....hd2 is working like a charm....thanks for all your support.

How did you fix it? For other users in this position.

SOLVED {bootloader dont loadArrow}
Here is what I did..
B4 that some background -
I used to heavily try different roms/mods and always played with android sd and nand versions…win 6.5X in multiple cooked version….
So my tmo-hd2 has been formatted/hard reseted/flashed many many times
By virtue of this….my screen died….slowly my screen touch responsiveness malfunctioned and eventually died… all hardware keys were working perfectly by the touch was dead….
During the process of screen malfunction to completely dead….made few observations to not things which might help fellow Hd2 owners…one thing is power/end key seems to be the culprit (this is my observation/belief).
Since I don’t live in US spend 100$ in changing the screen since then everything is working well…I still rig my hd2 like I always do…
Well when the wp7 was released, wanted to give a try…did this…hspl pkg 3 spl 2.08 hspl > then task 29 > and my hd2 didn’t get into bootloader at all…..i was doomed as there hd2 (after task29) didn’t hv os..
Searched for the solution everywhere and eventually nothing worked for me…I was about to give up…suddenly sometime struck my mind…wat if the power/end key is the problem….then things were positive..
I opened up my hd2 (unscrew and removed the back panel) and disconnected the connector flex rigid board (A board) of the hardware keypad from the mainboard….and pushed the battery in and pressed reset (sometime u need to plugin the usb cable to wall charged/pc to wake up the phone) and held volume down key and hopped for some miracle.
Viola saw the tricolor screen after eternity – since the back panel (not backcover) was open I help the battery to the pins and didn’t even move my fingers …run the stock rom installation and held the battery tight in place and waited to get the rom completed…the moment its 100% relaxed my fingers and reconnected the flexboard connector, re-assembled my phone and everything was back to normal…
ONE THING I LEARND FROM THIS…..HD2 IS A ROCKING PHONE AND U CAN RESURRECT IT WHATEVER HAPPENS TO IT (if at all some1 screws it with wrong radio…its officially bricked, but still it can be revived using RIFF JTAG method and rewrite boot data).
One final request pls DON’T GIVEUP ON YOUR DEVISE
Now I have wp7 running successfully and waiting for my activation code for live services

also hit thanks if u think its worth it

May I link to or rewrite and credit you with this in my guide?

interesting, two confirmations in this thread, and there's another thread where 2/3 people successfully used this method.
That whole lower right area is the Achilles Heel of this phone, keypad, screen connector and most pressed key all right in one little place.
Bring me the chief designers head on a plate!

Yes. The only downfall of the hd2. I wish it had the soft screen keys at the bottom.

yup...and the interesting thing is, i befriended an HTC engineer and got hold of multiple 'a-boards' at that time to test this out.the flex-board that reacts when we push the button.
there were multiple models/molds for HD2...may be different production lines..everything did the same job including the one which was shipped with the device..'a-board' wasnt the culprit here..the very design of having power + end call + device unlock in the same key/button is the issue.

HD2 touchscreen with MIUI rom won't respond !

I tried soft reset, nothing. Pull'd out battery reboot, nothing. Can you guys recommend me with a few steps i should take ?
Thanks a lot i really need my hd2 this week

Task 29, flash winmo stock, check if touchscreen if working. If it is, flash HSPL 2.08, flash radio, MAGLDR, then android, check if it is working, if it isn't then try a different rom. If from winmo it isn't working, then more than likely it is a hardware problem, eg. your end key is interrupting touch inputs, so take it into repair, although currently HTC is facing repair problems so if you're willing to wait say a month or so, then sure, but if it were me, i'd just buy a new phone.

Mann....i now feel that Android NAND is what gives users so many touch screen problems....yikesss !!!!

Im trying taks 29 now.

I installed this WinMo rom after task 29 and a hard reset:
Energy™-.¸¸.·´¯ 6.5|21916 / 6.5.X|29020 * Sense 2021
Still no touch screen. But the hardware keys are working. Will this be the end for me of a fantastic device and ****ing up 190 euro's

worst situation ever! when you slice your finger to unlock it and nothing happends !! it's a very common problem, HARDWARE related, not android nand related, i've been in the same situation after installing an app, somehow the screen became unresponsive.
i read somewhere that if you pressed a little hard above and arround the power button, the touchscreen starts to work again, because the digitalizer´s conectors are arround there, and i tried that and guess what?? it worked! after that installed button saviour app and never pressed the power button again.
but sadly, after a while the screen becomes unresposive again, so it´s just a temporal solution, now my touchscreen has become completly unresponsive and that trick doesn´t work any more

sounds like the digitizer issue thats been banded about on here

by the way, there are thousands of threats in the forum regarding the same problem, try to give them a read

I did read some, didn't gave me a single working solution. Is this a common problem with HD2's ?
My warranty is gone. Should i try to take it to a local repair shop ? Or take out my baseball bat and give it a good swing ?

It wasn't really supposed to happen you see. Android just requires us to use a lot of buttons and well, the hardware design wasn't meant for the buttons to be pressed a lot, so this happens, if you're unlucky.

Didn't use the power button that much really. Im thinking about selling my hd2 and buying a palm pixi to use for a couple of months. How much should i charge ? 60 bucks ?

[Q] Problem with ''slide''

The problem with the slide (left-right), ie. I can not to unlock my display. Since a few days ago I can not move the slide, i I have to turn off the phone (to remove battery), I worked reset, modified wallpeper and screen saver but nothing. Now I hold on my calculator, or some other program and it is only solution that I can to use my phone. Otherwise, touch screen works normally on all parts of dislpay. Does anyone know a solution to this problem?

Weird...

Are you sure your touchscreen works normally on all its surface and only unlock slide is a problem?
It seems very odd, never heard something similar...

Yes,it's wierd.. Maybe you could describe the problem better when it doesn't work etc. it could be some touch drivers problem
Sent from my HTC HD2 using XDA

I used to have similar problems . Have you updated to the latest rom from HTC. It can be downloaded from their website. ( be sure to back up all your personal stuff first of course)
Good luck

Yes I know that seems very odd, but it is, my touchscreen works normally on all its surface and only unlock slide is a problem. ''Touch drivers", how and where I can to find drivers? Last night I looked different solutions, similar problems on many forums but without success. I found and installed little program 'xda shutdown' and it is work.....with that program I turn phone to sleep.....when I need to use phone again I push button 'home' on the phone, and slide works normally (no button shutdown, because in that case I cann't to move slide left or right). I forgot to mention, I have Windows 6,5, rom 3.14.479.2 (04666)WWE (I think that is last officially rom), radio 2.15..50.14. I hope that I now gave you more informations. Thanks in advance.

sounds like a common hardware problem of the HD2. the power/end call button is one of the most used buttons and has been known to cause pressure on the touch screen+connectors underneath, which can eventually damage the touchscreen.
you are now using a way to turn off the screen that doesn't involve the power/end call button. also, you are now using a way to wake the device using a button other than the power/end call button. funny thing is, this is exactly what is suggested (as a workaround or troubleshooting step) in almost all of the many many threads that talk about the problem mentioned in the first paragraph!
search some more and most common permanent solution suggested is to have it repaired!

Thank you ASCIIker, do you think that this is now a only solution, there is no way to get things back as before?

[Q] Touch fail

hi guys I used to have wp7 on my hd2 and the touch screen work correctly after i install the android rom it works correctly for the first time running but when it goes to standby mod and i wanna unlock it the touch screen doesn't work and i testing a lot of rom and all of them have the same problem and it also work at the rocovery part whats your idea about my problem

Your device is most likely facing the infamous end button/digitizer dilemma. Since you said it happens after waking up the device from standby (using the power button, right?). As far as I know there is no fix other than a replacement. I don't really remember which part required replacement (digitiser or buttons strip), but I'm sure the only permanent fix was a replacement (until the replacement fails, lol).

If it is just the power button, you could use another button to wake up the phone using button remapper or similar app.
Also, use softkeys for back button, since the digitiser cable runs below these two buttons.

New digitizer is way forward & they like $10USD these days
Like mentioned above you may get some use if avoid pressing buttons but if intend on keeping device for a while repair is worth while.

Yes, at ebay you can get a New digitizer for less than $10USD.
