[Q] End key and touch screen - HD2 Android Q&A, Help & Troubleshooting and Genera

I "recently" (i don't know if it is recently or not) found that when i press the end key to wake up the phone from sleep mode, the touch screen doesn't work; when i press other buttons to wake it up, the touch screen works.
i don't know if your guys have the same case, please confirm me.... thank you

I have the exact same problem as yours. a disaster that strikes when you enjoying new rom every day?
or perhaps we press end button too often while flashing?!
Going to send to repair within warranty period. but require a week! gonna miss my HD2 so much after that
P/S: go to this link for temporary fix for this problem..

I have the same problem, and it's the digitizer, you can send it in for repairs, or attempt to fix yourself. Oh and it starts with the red button not working and slowly progresses to nothing working

Thanks for your info. i think i need to take it to the service center as well.

Read this thread. It explains the issue in detail and also shows a possible fix if you want to try it.

Digitizer gone - but not completely dead... Any advice? [VIDEO]

Hey my lovely XDA-ers, I'm really hoping for some magic here...
Yesterday my HD2 digitizer just stopped working... the Touchscreen will not respond to any inputs. It was bitterly cold outside so I was half hoping that an overnight stay in a warm room would help, but no avail...
The thing is, on one in every 5 restarts, I get a small amount of life from it. One one in 15 restarts, I get full use. So there's still life in there.
I could understand if it broke because I dropped the phone/squashed it, but at the time I was just playing Robo Defence, completely normal use, when all of a sudden it stopped responding.
I've uploaded a video, which shows how, occasionally, the bottom fifth of the screen works. However, as shown, when I'm using the top half of the screen, the digitizer appears to be receiving input from the bottom of the screen, as though I'm trying to perform a multi-touch action. For this reason I'm hoping there still be some way to rescue the phone without an expensive repair job. I bought it in March from XDA Marketplace, and it's served me faithfully since, but because of that I do not think I have the manufacturer's guarentee, or insurance
I've hard-reset, I've reflashed my ROM, I've tried in both WM and Android (my usual OS at the moment), I've reflashed over WM ROMs, and the problem stays the same... (also read all related threads!)
Sorry for inverted nature of vid!
So does anyone have any suggestions to try? Otherwise I might go through a £130 repair service on htcrepairs.co.uk - they do not show up on a forum search so I was wondering if anyone had used their service before?
Thanks all, appreciate any ideas.

Very odd indeed. I don't have a solution for your problem, but a suggestion. It is a long shot, but might help.
Whenever i had similar problems with my Wizard (i know, kind of old but one of the best older devices every made by HTC), i opened it and cleaned it from the inside and checked all the connections of keyboard, touchscreen, etc. to the mainboard. Sometimes it helped...
In the end, if you buy the replacement kit, you anyway have to open the HD2, so why not try this in prior to buying the kit...
A lot of people seem to have this problem. There's a lot of information on it here. Do a search. But the short answer is its a hardware problem. If your phone is still under warranty send it back. I think HTC will fix it for free if It's less than a year old. But try your carrier first.
Sent from my HTC HD2 using XDA App
BAD NEWS...
i had EXACTLY this happen to me. eventually it totally stopped responding. Only option is to replace the digitizer.
GOOD NEWS..
After a month of searching, I found a really good guy to do it. www.iexpertstudio.com . The owner is VINCE. you can email him on his site. He charged $110 including mailing it back to me. He replaced the LCD and digitizer and sent it back. All works perfectly now.
I see you are in the UK so dont know if it makes sense to send it to the US. Alternative is to go on ebay and buy the screen/digitizer and replace it yourself.
(BTW normally i would have chucked the device, but even after 1 year I still dont think there is as versatile a device as the HD2. Had the DHD been 3G useable in the US I would have bought one.)
Thanks for the feedback guys, I've been doing some investigation my end (and you're right, there are similar threads on here, but none which had a "half-screen working" problem.)
I've narrowed the culprit down to my "Back" button. It's somehow exerting pressure on the screen, leading to either a non-responsive digitizer or an input at the bottom of the screen.
I might add this to an entry in the "ANDROID KILLS YOUR BUTTONS" thread
My choice is to live manually with it, or get the company mentioned in the first post to give it a good clean, but whether it's worth £80 just yet is a question for me.
Anyway, thanks for your input, guess this thread will close, but to any readers in future, if your screen seems to die, see if it's pressure on the screen caused by the buttons!
I can totally support your reasoning.
I haven't had any problems whatsoever with the touchscreen in almost a year of honoured career of this phone, while this morning I was trying to unlock it with no success (nothing special happened, I even used it 10 minutes this morning already). At first I thought it was the usual "sleepy" behaviour of the screen right after waking up, butafter sliding down the hdmini style unlocker at least 10 times with no effect I really started freaking out :O
I have longpress endkey set on instant reboot, and after that it seemed working... just not for too long.
To cut to the chase, what in my opinion supports your idea of hardware buttons interfering is:
sometimes, as I have LMT installed, with the tap&hold option enabled, swiping with just one finger triggered double swype instead (as if the screen detected a second, firm press on the screen elsewhere even if I sure as heck was swyping with one finger)
using mymobiler didn't work as well; if it was a hardware touchscreen problem, mymobiler should work, as it simulates touches, so it will just do its job even if the touchscreen is totally dead... while, IF the hardware touchscreen detected a firm press somewhere, mymobiler wasn't able to actively simulate another press
repeatedly pressing on the end key (which seems to be the culprit in my case) apparently solves the problem, as I can use the touchscreen again; also, a prolonged cycle of hibernating with end key, waking with end key, swyping down the hdmini lock (repeat at libitum) seemed to work, as if I dislodged something by activating the button so often
What I don't understand anyway is: HOW can a button pressing on the digitizer be exerting a touch action? If this was a resistive screen, I'd understand, but it's capacitive, and not even capacitive pens are so good as fingers in activating the touch. The buttons are just plastic with a metal contact underneath, and this metal contact shoudl by no means be anywhere near the digitizer.
Bah.
I know I have 2 years warranty on this device, but being far from my phone during the warranty processing gives me the creeps, so I'll just go on using it and pray this to be the defaillance of one sunday morning not to be seen again... after several soft resets (and fantasizing about a new rom flash, which I need anyway for other reasons) the problem seems to have settled by delicately bashing on the end key. The unlock slider is responsive after every wake up now... FOR now.
Praying...
My screen also died. So the only thing I have to do is press on the end key for a couple of times to make it work again?
lol, that's ONE possibility.
Just saying, in my case it worked, and still does since it happened once more this evening, so it's definitely got something to do with the hardware keys messing around (and hopefully dislodging themself for good, or I'll have to send it back for servicing), anyway in your case it could also be a dead digitizer, so no go
let's put all this about touch screen in 1 sticky thread pls.
I've been living for the problem for about three weeks now. It's never got worse, but never got better. It's a livable situation so for the moment I'll deal with it. I might check with HT about warranty, but it's not yet bothersom enough to make me want to flash back to stock, send it off etc. etc.

ditto.
Actually, I don't like having paid good money for a defective phone, but being without HD2 for up to a couple of weeks to one month (maybe? have no idea how fast HTC servicing is) is troublesome. I may buy for a deal a blue angel as a spare, yet, no GPS...
The most problematic event is if you get the "stuck" screen during a call.
In my case, it's the end key that messes it up; if the screen's dead, pressing twice the end key, firmly enough (once for screen off, then again for screen back on) wakes up the screen, and apparently, during a ringing incoming call, you can press the hardware end key without rejecting it, so it's a viable option (not taking into consideration the fact that trying to wake up the screen takes time, and the caller may give up after a while if you're not fast enough).
But if for any reason the screen gets stuck while the call is connected, I am stuck too, as to wake it up I should press the end key thus hanging on the other party.
Sad story.
EDIT: forget what I wrote, pressing end key while phone is ringing WILL reject the call. I tried it before during a real incoming call and apparently it didn't do it, but now it just did.
I also have a HD with a dead screen....
Only thing here is I have sent it back twice already to TelSuck here in Australia only to have it returned after the tech has wiped it over and reflashed it for me... What helpful little imps they are!
Code:
http://www.youtube.com/v/T6ssqmpRIB0
Its drivin me nuts sending it away for 3 weeks at a time to have someone with just enough grey matter to be able to wield a screwdriver tell me nothing is wrong.
Happy to try any suggestions!
@insinr8
this thread is just for half-dead screens where the screen sometimes actually works. Unless you can resurrect it by firmly pressing on the hardware keys, but if it's dead on a regular basis, then it's not our same problem I'm afraid :-(
@OP
while having an "attack", did you try plugging out the microsd to see if it magically solved the problem?
I mean, if it did, it would still be a hardware problem related to the microsd slot, since there is no point for a faulty microsd to mess up the touchscreen, and let it work from time to time

I will try that - it seems to happen more frequently when plugged in and charging, and now more buttons seem to be the cause/fix (e.g. now the home-button, or when I am on home-screens the phone will swipe "left", whereas before it would swipe "right". I'll keep playing.
I may check out HTC as I reckon my warranty, if I have one, will run out soon... Will still wait til after Xmas as I need my toy for the boring bits of Xmas!
I'm having same trouble now whit my phone except problems started mouth ago. After some period I again power up my phone and suddenly everything worked perfectly. Unfortunately this last only for two days and then exactly same problems happened, partially function screen.
As far as I know only good solution is replacing digitizer... I already ordered one for me.
exactly the same problem for me.. I sent it back with warranty yesterday

Ditto.
Actually, my warranty lasts two years, which means until 2012, anyway I cannot stand risking to lose calls because the screen dies on me in the wrong moment, and the only way to wake it up is pressing the endkey (which by the way is the only "cure", and apparently never the cause).
I will be uploading a video on youtube regarding this, also to show it to the guys at the HTC support who will be asking me to hard reset and reflash until annoyed to death (as if that will solve anything)
Bump
This is the video that I just uploaded to youtube:
http://www.youtube.com/watch?v=C3-PNYwpYeI
EDIT: One day after, the problem has become way more frequent, 1 out of three times I wake up the phone, diugitizer is dead and I need the " on the end key to make it work
Uploaded another video on youtube with problem showing on vanilla lockscreen so HTC support doesn't try and tell me it's CHT lockscreen's fault
Last bump.
Screen has ben promoted from "hardware key problem" to "permanent death".
Now I can use the phone with mymobiler, but I can't anymore with touch, I seem to not be able even to wake it up even by pressing on end key
Re-flashing last official rom upgrade now to see if anything changes... yeah,sure
Ouch - good luck, hope mine doesn't go that way...

Return button not working/off

I just got my phone back from Samsung and they replaced the board due to bad internal SD....now..this new phone is working great....BUT
The return button (right of main physical button) turns off and doesnt want to work.
It seems like it gets stuck as pressing the main home button will take a screen shot.
Is this a known issue?
It stops working...then a few min. later it works again for a bit. Rebooting doesnt help it. You just have to wait it out.
Any way to calibrate it?
Send it back to samsung?
My currently dead i9000M did this. Usually only when you pressed Home and Return really quickly.

Really? WTF!
I thought it was just my phone...and this phone just came back from repair!
I just called samsung and told them about the issue. They told me to call the repair shop in Montreal tomorrow and tell them about it as they need to close off my old ticket so a new ticket can be reopened.
WTF..they dont do extensive testing of the phone before shipping it out to customers!
I get the same as well. When running the authorized Bell/Samsung ROM's (JK3, JK4 and JL4) I see it quite often.
Now that I am using a custom ROM based on JPY, it occurs less frequently. I can't seem to duplicate the steps it takes for the issue to arise.
As @rmanaudio mentioned, once this occurs and you press the "Home" button, a screenshot is taken.
I'd be interested to know if the new device that you receive has this issue fixed.
is this the problem that occurs for you in this thread?

[Q] Ghost key pressed, worse with MDJ recent update.

search for "ghost" "key presses", nothing relevant so here we go, hope to get a response on this one or I am going back to another ROM
I am getting really bad ghost key presses with this ROM, I used them with WINMO roms but a fix was released. This suggests the screen driver for Android is not yet stable and needs more DEV or is it just me that is having this problem. Sometimes it is so bad I feel like dropping back to winmo, yes I know it is that bad.
issue 1:
Sometimes all the keys around that key I am pressing fire and not just once, several times, mostly on edges of screen.
Issue two:
Sometimes when I have finished a word I get lots of ghost presses and random characters as if I am running my fingers all over the keyboard.
Could my screen be faulty?

I saw that, however the problem pretty much goes away on winmo ROMS, dont want to go to the bother of removing spl/mag and android to send it for repair if it isnt broken, are you 100% positive my screen is damaged?
Yes dude ...100% sure ...when i had this problem it was negligable on the windows mobile and more on the android builds...its sooo anoying ....just get ur screen replaced ...u will start loving android buils
Thanks, I will look into this, phone is still within warranty.
He's right, see my thread here. I had exactly the same problem as you. Sent my phone back to HTC, replacement screen, no more bounce/ghost keys.
didnt see that, didnt think of searching for "bounce"
I have put in a support email to HTC.
@Major_Sarcasm --- i still remember how much i had to convince u to change ur touchscreen !

Not Unlock after StandBy

Hi All, I have a problem with my HD2 I Update the radio to 2.15.50.4 and when I want to unlock the screen the touch do not respond, i back the radio 2.12.50.2 and the same thing not unlock, anyone Know what is the problem, sorry for my english and Thaks to all.
I change the Rom Too and the same thing, for reference.
Try turning it on with the green button instead of the red one. Mine was doing this, had to send it in, it's a hardware problem between the buttons and the digitizer. Needs to be replaced if it's the same problem. Seems somewhat common. Even flashing back to full stock didn't fix it, it was definitely a hardware issue for me. If you're changing roms, and it's still happening, that doesn't sound good.
Sorry for the bad news, it sucks.
Thanks Willr001, Look similar to your problem and it's the same thing, with the rest of the buttons don't have the problem, how much cost to you to fix the problem??? and thaks for your answer, thanks to you now can unlock my cell, with problem but can unlock.
I don't get how it could be the buttons if you're able to get in to MAGLDR using the power button?
The problem will keep getting worse, I think it will next stop working with the green button, mine took like 4 days from the time the red button stopped working to the green button stopping.
The red button still works fine, it just makes it so the touch screen doesn't work, so MAGLDR would still work fine.
I don't know how much it costs to fix, I'm not sure if it's the buttons, screen, or motherboard that needs to get replaced. Mine was under warranty, so they fixed for free.
HTC knows it's a defect, if you're under warranty, their service center may do it for free.
Thanks for the answer, yea the i can go MagLDR with the red button, and unlock with any other button exept the red, I will verify if si still in warranty for make the same that you, by the way do you think the posibility of change to WM 6.5 to look if the problem remain in that Rom?
You could try, when it happened to me I flashed another WM6 rom, still happened, so then I flashed the original Stock T-Mobile/HTC rom. When it still happened there, I knew it was broke. Made it easy to send back though, because I'd put the stock rom on (warranty people like to see stock roms).
i can't see this is cause by hardware failure. It seems to be a hardware buttons mapping problem so its mean just the software.
I think too that is software problem because I don't need to prees the button to block the screen, only with touch on the button without press is enought to stop function the screen, but i don't have warranty Yet, so I try to solve this for my own, I apreciate all help that you can give me.
i9m having the same problem, i fixed permission and then all buttons wont work. ill try to reinstall the rom and see if the problem will be resolved. im so depressed right now.

[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
I have http://forum.xda-developers.com/showthread.php?t=933951 on my hd2 and theres an option in cynogenMod settings > input > long press home settings that lets you change the action that happens when holding down the home key. Just set that to "screen off."
