The SOD problem on my HD2 does NOT seem to be hardware button related, but perhaps SD card related.

Often the screen turns off (goes to sleep) after I receive a call. After I end the call with the End button, the button&LCD backlight turns on, but screen remains black (but I can see the backlight is on).

It doesn't make a difference if I accept the call with a hardware button or the onscreen slide button. It doesn't make a difference if I select an internal ringtone or one from the SD card.

The phone still responds to key presses (if I receive another call, I can still accept it or end it), but the screen refuses to wake up (and I can't use the touchscreen).

A way to wake the phone up is to plug in a charger/USB cable, and sometimes an incoming call wakes it up.

HOWEVER, if I remove the SD card, I don't have the SOD problem. I tried with freshly formatted Sandisk 8GB and 16GB cards (Class 4 and 2), also tried formatting the 16GB card with 64kb clusters.

I'm using TyphooN 2.6.32 (http://xdaforums.com/showthread.php?t=933951) and radio 2.15.50.14 (and tried the 2.14 and 2.12 radios).

Simple solution if you have a warranty, useful post if you DON'T like me!
[HD2 Android Q&A, Help & Troubleshooting and Genera] XPLANE9:
Is this prone to happen to all HD2s? I have had my for a year so my warranty is gone, but I have no touchscreen issues at all. Wasn't there a case where if you press down on the lower right corner of the HD2, the touchscreen would respond to it, even though you are only touching the bezel?
[HD2 Android Q&A, Help & Troubleshooting and Genera] eugenile:
I had a total of 5 TMOUS HD2s.. 2 of them suffered the SAME demise. touch screen starts to be unresponsive. mostly coming from sleep state. if you turn on with red button on right big chance touch will not work, but wake with green or or other buttons will work.. eventually it will just go out to where the percent of it working at all becomes very low to where its just not fun anymore..

this is where we are now.. is it truely the hardware button, or is it the digitizer.

not rom related. its as described in THIS thread. people speculate its the hardware button on the right being stuck dirty etc, but someone just mentioned that its not and a digitizer problem. Hearing people's results will help narrow down the true problem.

Someone who has this problem and able to dissect can help. is that end button right by a ribbon cable or something that after a while wears out the connection on the digitizer to where it has to be replaced? maybe doing something ghetto like adding an extra cushion or spacer there to relieve tension.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Hd2Menace:
Experiencing this right now. When I use the Power (Red) button to wake the screen, the screen is unresponsive, can not unlock screen. But when I press and hold the Green button and slide to unlock, it works. It randomly works on the buttons (except Red button) and sometimes it doesn't work at all. It gets very annoying, especially when I get a text or when the alarm goes off. It happened this morning when the alarm went off. I couldn't stop it from ringing until I removed the battery. Have anyone actually took apart their HD2 and clean underneath the buttons? Can you give us a tutorial on how to take it apart and clean? If this persist, I'm thinking about getting a new one through the T-mobile insurance policy. But I really don't want to go through the hassle of filing a claim if there's a solution like taking it apart & cleaning it. I'll take the risk of taking it apart since I have insurance on the phone. I like my HD2 and still want to keep it. I love flashing and customizing it!
[HD2 Android Q&A, Help & Troubleshooting and Genera] AngelDeath:
There is a video I posted above on how to take it apart. Also I posted to apk links to avoid using the red end button. If your phone is unresponsive, press the red button about 10 times quickly, and then try, if it works DONT TOUCH THE RED BUTTON! and use the green button, windows button, or the back button. Use the end key for only when your powering it on from off position.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Hd2Menace:
Thanks. I just saw the video/link.

why don't you just claim that it's broken...then your not lying since the screen doesn't work. Reporting it missing is asking for trouble.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Hd2Menace:
I'll flash it back to Windows and claim that it's broken. Hope they send me a new one instead of fixing it! It was just the thought of not having a phone while this one is being sent in and flashing it back to WM.

Gingerbread GPS driver is not working. Switch off the GPS and the SOD will go away. I have been testing the SOD for weeks now and you don't get any SOD if your GPS is off. We are busy developing new GPS drivers for Gingerbread but progress is slow.
[HD2 Android Q&A, Help & Troubleshooting and Genera] evilmika:
I'm not sure if others encountered this issue but my touchscreen problems seemed to be caused by the MAGLDR/CWM combination. Previously, I was using MAGLDR 1.11 and had no problems with MDJ CM7. I decided to try Typhoon CM7 cLK which worked fine and then all the problems began when I switched to MAGLDR 1.13 with CWM recovery (same problems on Hyperdroid, CM7 nightly, and a few others). I got the infamous power button issues where the screen would turn on, but I couldn't unlock!

Just now I switched back to the lastest Typhoon CM7 cLK version and now I don't have any problems with my touchscreen again! I realize this isn't the most extensive testing, but its something that others might want to look into.

tl;dr

MAGLDR 1.13 with CWM recovery gives me touchscreen problems

cLK no problems

EDIT: seems the problem is back and must be a hardware issue as stated by others. Will be calling htc and hopefully getting this all fixed up
[HD2 Android Q&A, Help & Troubleshooting and Genera] masondoctorjt:
I had this problem. Definitely the end key. Press it hard and the screen would work again for a while. I called HTC since I bought it off craigslist. They asked for the SN, I gave it to them and they said it was under warranty still, even though it's over a year old. I sent it in and they fixed it the same day they got it. I got it back and they apparently replaced the digitizer since the scratches were no longer on the screen. So, if your screen is scratched like mine was, it's nice just to get the new screen at least, but anyway it works fine now, and I am careful to use the end key sparingly and when I do use it I press it very lightly.
[HD2 Android Q&A, Help & Troubleshooting and Genera] pappt:
If this problem caused by the End/Power off key, then we can say there is a connection between the magldr and the unresponsive digitizer . Because if you want to flash a new rom, you have to got to the magldr menu, and how can you do this? Yes! You must push the power off button for long time. Perhaps we can ask Cotulla to change the method to go to magldr menu in the next release. Just as in CLK (another nand loader) where the Home button must be pressed instead of End key...
[HD2 Android Q&A, Help & Troubleshooting and Genera] Hd2Menace:
So you sent in the phone while Android was still on it? I'm going to give HTC a call then instead of T-Mobile.
[HD2 Android Q&A, Help & Troubleshooting and Genera] hmnmcoupe:
There is a connection with red button. My touch screen works fine once I avoid that red button. I called HTC and gave them my SN and they said my phone is out of warranty. They said if I can provide a reciept then they will offer the warrantly. Unfortunately I bought my phone off craigslist. That red button is used for everything. Bootloader, CWR, screen dimming, call end. That button is bound to fail. Now to figure out a fix...
[HD2 Android Q&A, Help & Troubleshooting and Genera] martijn5380:
That's true.. but you forget that you don't use the touchscreen in Magldr. As you may know, the hardware buttons still work when the screen is frozen.

I'm afraid the problem is just poor quality technique for the buttons. For example, my five year old HTC touch is still working completely. And I've used the power button on that device more than I ever will on any device:p

Anyway, I flashed my phone also back to stock, still the same problem on Windows Mobile 6.5. After seeing wm 6.5 again I sent my phone for warranty as soon as possible. Now waiting and hoping I get a new device :)
[HD2 Android Q&A, Help & Troubleshooting and Genera] Hd2Menace:
Called HTC to repair my screen. This is the e-mail they sent me incase anybody wants to know what they should do when sending it in. I flashed it back to Windows Mobile before sending it in but can anyone explain to me how to uninstall HSPL?
[HD2 Android Q&A, Help & Troubleshooting and Genera] martijn5380:
It's very easy.

- Look here (http://theunlockr.com/2010/04/22/how-to-get-the-htc-hd2-back-to-stock/) to download your Stock ROM, for me it was NLD HTC HD2 Stock ROM/SPL.

- After downloading, open the EXE file with WinRAR (or another archive file opener).

- You will see that there are multiple files in this EXE. Extract only the RUU_signed.nbh.

- rename the RUU_signed.nbh to leoimg.nbh

- Connect your SD cart to the computer. Optionally: format SDcart and copy the file leoimg.nbh to the SD cart.

- Put the SD cart in your HD2, and reset your phone (or just turn it on)

- Hold the volume down button while to enter Bootloader mode. The HD2 will now automatically flash Stock ROM and Stock SPL.

- After flashing, enter Bootloader mode again and check if HSPL dissapeared.

- Your phone is now back to stock :) I did the same for my phone yesterday, hoping on a fast repair.

Looking at the email they sent you, did you have to pay the $39?
[HD2 Android Q&A, Help & Troubleshooting and Genera] Hd2Menace:
I didn't pay the fee yet. Still need to mail my phone out. They said if anything is out of warranty, they'll give me a call and let me know how much it would cost before charging to my card. I'll update when I send/receive my phone from repair. Going to be a while. 7-10 days.
[HD2 Android Q&A, Help & Troubleshooting and Genera] CharlyAR:
I have to agree with you. It just happened to me and I came here googling "digitizer power button", hehe.

Now I'm at the verge of killing myself. I played around with the power key but won't work.

Any recommendations? Opening it up is out of the question for a few days (I don't have the tools here). Also I would like to avoid taking it to a service since they charge too much in Argentina. :(

Cheers.

[HD2 Android Q&A, Help & Troubleshooting and Genera] bugdeyez:
I wish I would have found this sooner. I was going crazy for 2 days trying to figure out how to use the phone again. I dont think it is a matter of debris or something, because I have only had this HD2 for a month or so since I got it as a replacement for the last HD2 that I sent back for this problem. It definitely has something to do with waking the phone with the end key.

I thought I figured it out and was ready to start sharing. haha you beat me to it by over a month. Good work.
[HD2 Android Q&A, Help & Troubleshooting and Genera] atsavlis:
Well guys, hopefully I can shed some light on this problem.

My HD2 would give me the same problem from about the 3 month after I bought it... The "screen freeze" would come and go, but mostly my phone was functional. About a month ago, the screen totally froze, anything I did, didn't work, even pressing the end key hard.

I took my mobile to HTC (Greece), and they called back quoting me 560 euro for a new screen and digitizer, and also a motherboard because I had apparently spilt something on my phone, and the warranty was void. With 560 euro I could easily buy a brand new phone. I told them to leave it and decided to take matters in my own hands....

I looked through e-bay, and ordered a lcd screen together with the digitizer and the tools needed to open the phone for 60euro. The screen arrived, and after about an hour of REALLY careful work, my phone is working like brand new.

The problem lies in a small little chip that is right above the end key, this chip is where the digitizer and lcd screen "join". So when we all have our "freeze" and press really hard on the end key, we in turn push onto the chip, causing a temporary fix.

Google HD2 lcd digitizer, and look at the images and you will see exactly what I am talking about. My phone has been working like a charm with NO freezes at all for the past 3 months.

So much for me needing 580 euro to pay for HTC electricity bill. Ohhh and the moisture stickers on the inside of my phone where still white, which means there where NO traces of moisture.... I think HTC just tries to kill us on aftermarket parts. Anyway, I hope I helped out with this problem...
[HD2 Android Q&A, Help & Troubleshooting and Genera] AngelDeath:
atsavlis,

Thank you for sharing that, it at least shows that it is possible to fix, and your explaination of the fact of the chip sheds some more light, but the curious question I have in general (mayb you could answer it) is if what you said is true that the chip lies just under the end key, what is the reason pressing down on the end key presses the chip that causes it to come back to life? Did you notice a break and the pressing the end key makes the connection again? because ever since the issue with my test phone started, I installed quick reboot and Screen off, and the phone works fine, so it makes me wonder why is it after it works pressing the button again would make it stop again, unless the button sticks and it lifts the chip again.
[HD2 Android Q&A, Help & Troubleshooting and Genera] atsavlis:
AngelDeath

The chip isn't directly under the end key, it lays just above it, and the chip looked pretty normal, no cracks or signs of force. Possibly the constant pressing of the end key might have something to do with it, but in my case, it had sarted way before I ever thought of flashing anything to my phone.... So basically my end key was used to switch my phone on or off, which hardly ever happens as it gets charged before it dies.

Check out the above, im sure you can see what im talking about. I doubt dirt has anything to do with it, If you ever open up one of your phones, you will see how well sealed up they really are. :p

P.s - Just under the little white sticker to the right of the chip, is a soldering that is where the digitizer and screen are soldered together, just pointing out that, that is another "weak" spot.
[HD2 Android Q&A, Help & Troubleshooting and Genera] AngelDeath:
Ok not to sound like a total ass, but looking at that picture makes me ask another stupid or not so stupid question, looking at the picture on the right, something puzzles me now. Obviously the opening on the bottom is where the keys go, provided assuming that the left picture shows exactly how the screen and wiring "drop into place" and the side ribbon probably is bent downward to attach to the main board, I dont see how the end key would affect the chip you speaking about. because clearly on the picture on the right it doesnt seem possible because it looks like the chip is actually above the end key in that small section between the screen itself and the end key. Sorry not trying to be difficult, just making an observation.
[HD2 Android Q&A, Help & Troubleshooting and Genera] atsavlis:
Lol, thats what I thought, but you would be amazed at how crammed and tight all the parts fit together... before I removed my screen, i had my phone opened up, and booted it up, i tapped on the chip with my nail slightly, and I would get temporary screen response... At one point with my old screen I pushed down on the power button really hard just in case it fixes it, and you could see the lcd screen in the bottom right corner make those funny colors it makes when u push on it... point being, the gaps between parts are so small, that the slightest pressure get transfered around...
[HD2 Android Q&A, Help & Troubleshooting and Genera] ceo4eva:
Hey guys i dont know whats going on but like a month ago my problem with the "end button" started, i read this thread about using other buttons (which i did) but now today as i was using my phone i let it time-out on its own. About 3 minutes later when i try to unlock my phone none of the keys worked.

I pulled my battery 5 times (once for each key) and i still couldnt get the slider to move down.

I consider myself a light user of my HD2, not rough with it at all, so i dont know what the problem is here..
[HD2 Android Q&A, Help & Troubleshooting and Genera] eugenile:
Thank you. If you look at my posts in this thread I had always had ahunch it was exactly whay you explained. People gave insight and process of elimination led to your findings. Its just no one was willing to take apart and analyze.

Installing an app or some other is not a fix. Its a bandaid and we should not succumb to that imo. The real fix is what you did.

You think we can take preventive measures by adding a cushion to help with the pressure. But you said there is little to no space at all. I hate for it to happen again.

I ended up selling my hd2 with this problem and getting a working one. I put button savior to prevent using end key as much as I can. But that freaking sucks.
[HD2 Android Q&A, Help & Troubleshooting and Genera] reijkelhof:
I downloaded an app from market called Screen Off and Lock, which allows for a 'swype down' finger action on the home screen to turn off the screen and lock the phone, or to be used as a widget.

It helps.

would love to find a program like 'LMT on windows mobile', in which you can use all kinds of gestures, even in other applications.

(button saviour didn't go well with heavy games)
[HD2 Android Q&A, Help & Troubleshooting and Genera] atsavlis:
Unfortunately there is no space for any sort of cushion or anything to help in that way... All I could think of doing when I had my phone open was- The lcd + digitizer module is stuck on a plate with double sided tape.... I just looked around for really good quality double sided tape, and hope that it makes the difference.

The funny part was that a guy I know over at HTC swore that parts that are off ebay 90% of the time dont work, or are not the right size. In my order I did the mistake of ordering the lcd+digitizer for the t-mobile leo which has 1-2 tiny differences, amazingly it worked perfectly, and for some reason I feel my phone performs better than before (might be my idea)
[HD2 Android Q&A, Help & Troubleshooting and Genera] baymon:
Hey everyone,

Thanks for all the input, at this point I just hope that HTC Sensation will be released soon enough before this HD2 dies completely.

I started experiencing this problem about couple weeks ago, and all of the advices on avoiding the end button has really helped.

However, recently I noticed another different behavior regarding the unresponsiveness. For a couple times (I'd say about...5-6x so far), I swear that I haven't pressed the end key at all, but when I turned on the phone using the other keys the digitizer is still stuck and won't respond to any touch. Furthermore, if I try to the trick by gently pressing on the left side of the end key to "wake" it up for a couple times, the OS will get stuck and all I get is black screen and lighted back keys -> pull the battery out.

I was just wondering if anyone had tried to verify that it's not a kernel issue? I've had this problem ever since I flashed Coredroid 1.6, which I think uses Rafpigna 1.9OC or something. I had briefly tried Imilka's RAM DHD 2.0, but that one also uses rafpigna 1.9OC and I did have the unresponsive screen problem as well.

For me now, it seems that it's not just the End key that's triggering the dead screen, something in my ROM is also doing it for no reason.
[HD2 Android Q&A, Help & Troubleshooting and Genera] atsavlis:
I don't think it's a rom or kenel issue... Mine would do it even with the latest winmo rom installed.... In mo opinion, it's a hardware "weakness"
[HD2 Android Q&A, Help & Troubleshooting and Genera] Gustopher:
Whether or not it adds a great deal to the debate, here's my experience and opinion.

I'm not convinced that the OP has correctly identified the cause (but can't say why or come up with a better hypothesis), but they have done a stellar job in finding a solution for the symptoms. I can recreate the problem in Android time after time and the fix/workaround always works...so far.

However, in common with others, I have a dual boot WP7 set up and I can work flawlessly in WP7 for extended periods without encountering the digitiser issue. I had my digitiser replaced by HTC less than a year ago and while this is no guarantee that the problem couldn't recur, I'm inclined to look for a cause outside of the hardware.

I have swapped Android builds quite frequently over the last few weeks but didn't see the issue on the first couple. Where does this leave me? Puzzled!
[HD2 Android Q&A, Help & Troubleshooting and Genera] ceo4eva:
Can anyone make a video showing how to clean the hardware keys
[HD2 Android Q&A, Help & Troubleshooting and Genera] atsavlis:
This won't help in any way.... I opened up my HD2 and repaired my screen and digitizer, and after 1,5 years of heavy use, there was no signs of dust or junk entering under the keys.... Personally after the lcd and digitizer repair, I have not had a single issue...

i strongly recommend you all to stop using your end key!

since my end key start causing my all kind of problems i started to use 2 apps that made my life much easier.

1) softkeys - it's the same as buttonsavier but i prefer softkeys :

https://market.android.com/details?id=net.hoopajoo.android.SoftKeys&feature=search_result

2)Proximity screen off - this app really help me out i can put the device to sleep or wake it up just by move my hand over the proximity sensor, also this app help with the problem of answering or rejecting calls while you trying to pull the device out of your pocket.

while the device is in the pocket the screen will remain off and when you pull it out the screen will turn on and you can answer the call.

any way it's a great app for put the device to sleep.
