Just got a s/h exec and I think it is faulty. Whats happens is it starts up ok and works for a while and then for no reason that I can think of it goes into a loop which stops it from working.
When I say a loop I'm not sure thats the right terminology but imagine if you tapped the start button and the start menu opens... and then imagine you tapped the tab button , the next item would highlight. If you tapped the tab button again the next item would highlight and so on. Well its as if the tab button is being hit over and over because all the items in the start menu will be highlighted one after the other over and over again.... it just goes round and round in a loop.
Its possible to escape from this and go to another screen but the same looping will go on in that screen too.
If you switch off and leave for a while and come back to it it works ok for a short time and thens starts the carry on again.
Sometimes if you just wait a while it stops, but will start doing it again even if you dont touch anything.
I've noticed one way to force it to stop is to slide the volume button... this seems to stop the loop and allows normal function for a while.... then the crazy looping starts again.
Has anyone seen this or know anything about it.
Nope sorry, maybe you can have it replaced where you bought it as from your post, you can recreate the problem easily.
Side Note : Have you tried Hard Resetting? Or installing another ROM?
I have tried hard resets and factory reset... problem remains.
Will try new ROM.... just trying to figure out how to do it !

Just download a new ROM form imate or something, unpack all the files in the ROM update to a directory, put the attached file in same directory.
Enter bootloader mode (Backlight + Power + Reset Hole) you will see SERAIL on the screen but not backlight so look hard.
Plug into PC, the SERIAL will change to USB
Run the attached file. You will see a photo of an S100 but continue anyway....
Hard reset when finished... DOne
ok have installed latest rom... but exec still doing loop loop
Just for arguments sake, can you try installing Imate's newest ROM?
yea thats the one i have just put on.
It seems to be doing the problem less than before. I notice that it does stop if i press the backlight key or move the sound slider.
I'm wondering if there is dust or dirt got in behind the buttons or something like that... although I would have thought other people would have come across this b4 if that was the problem. The machine is one of the first to come out, although I just got it a couple of days ago.

If you have tried different ROM flavors and still get the same problem, then it is definitely hardware related. Send your unit in and demand for a new one not a repair
Just been playing around with it again and notice that I can make the problem happen if i press any of the keys on the navigation pad except the top one.... and i can stop the loop by pressing the light button.
Weird or what.
My initial thought on this is maybe its got wet at some point
I have opened the xda up and stripped it down to all its parts. No sign of any dampness or dust dirt etc. Dont see anything missing or broken.
Put back together, but still doing this.
Driving me nuts.... its a great machine but is very tiresom to use with this going on.
Another think I notice about this machine, I have never used it as a phone, but I tried putting a sim card in and There is no sound through the earpiece. Only sound comes from the speakers when you set it to speaker phone.
I suggest just return it and have it replaced. It's probably a faulty button. Probably gets stuck whenever you press it.
Doesnt need a button to be pressed for it to start.. just starts by itself... and can stop by itself too.
Sometimes it can for ages without doing it, other times it does it all the time.
Cant figure if its hardware or software problem
GHOST-IN-THE-MACHINE
Yea... maybe I should get a priest !
I had this problem when i first got mine, if you move the sound slider down, then up, it seems to stop doing it for a while, and it hasn't happened in the last couple of weeks atall, maybe its because its new, and just needs to settle in?
Jay
Well at least I'm not the only one to have it.
My sound slider does stop it happening but only for a while and then it starts up again.
The machine is perfect in every other way, its just an annoyance I could do without.
I've tried everything, even stripped it down and left parts out, like buttons, to see if they are the source, but no difference.
I have the same problem!!!!!!!!!
Someone help please!!!!!!!!!!!!!!!!!!!!!!!
I have same problem. I send to service but until today they can't repair that problem.
Hi all.
Just got a JasJam about 2 weeks ago.
I am have a problem with the touch screen.
After about 5 mins of use the touch screen slowly gets more and more unresponsive untill it stops working.
If i remove the battery and let the phone sit for a couple of minutes then restart it the touch screen would start working again. But for only 5 mins.
Is this what everyone is refering to as problems with Screen Allignment or do i have a bigger problem.
Does anyone have any suggestions on how to fix this problem.
Thanks
Travis
Personally i would do i hard reset and not install any additional software to see if you have the same problem. If yes, then its hardware problem and needs to be sent in for repair. If not, then install your programs back one by one to find the culprit.
S.K.
EDIT: Ensure you back up your data before performing a hard reset. You will lose all information stored on the phone.
Silent_Killa's advice is what I would do. Might try uninstalling apps one by one first??
This is NOT the screen alignment issue - I don't think. It depends if the screen responsiveness going off is actually at the point at which you tap the screen is not matching where the screen responds?? In other words it does respond but not at the location you tap. If this is happening then it is the SA issue, but if the screen does not respond in any way to taps then I doubt it's the SA problem - though could well be a digitizer issue.
I have not searched, but a week or two weeks ago an identical problem was posted by someone else.
If a hard reset does not cure this I would suggest a return as soon as possible.
Mike
Hey guys.
Yea i trided the whole hard rest thing and it still did the same problem.
The screen works fine but it is just the tapping part that gets screwed up.
All my hardware buttons work ok so i can still use the phone. I just can't use the touch screen.
Do you really thing an application could do this sort of thing.
The main ones i use are -
SPB Diary
SPB Pocket Plus
Spb Weather
Pocket Informant
Are these know to cause any problems.
I will try one more time and not install any apps.
Oh well 2 weeks old and it's off for repair.
Thanks for your help.

BUT surely you tried it for an hour or two before installing anything!!?? And if working then only one application at a time?
No I don't think any of those apps. are the cause of the problem.
You still have not given full details about whether the screen is completely unresponsive or misaligned.
Either way if it's under warranty and hard reset does not cure it, get it returned cos this is not some little software fault.

Yes, it was me (I think), I had this problem too. It was only when the keyboard was slided and locked opened. Button would respond but screen would freeze and the start menu, sometimes, would pop up as an extra.
I had to give it back ...

YEP that is exactly what mine does sometimes. After i open the keyboard the start button would start to pop open and close.
How did you get on. Did they tell you what the problem was.

Sorry, about that.
Full Details-
Screen has no problems with SA. After about 5 mins the screen slowly becomes more unresponsibe. IE i would have to tap the start button several times for it to work. When it finially pops open it just closes again almost straight away.
Not long after this the screen will become totally unresponsive, howver all hardware buttons will still work.
I am going to try a hard reset tonight.
I will let you konw.
Thanks again.
Well it is deffinitly my phone.
The screen wasn't working as per normal.
I hard reset my phone. When it rebooted and got to the "tap the screen to continue" bit. Guess what it didn't work.
I taped the screen several time but no go. The screen was dead.
I will have to send it back to the shop.
Cheers.

JasJam screen responds to "ghost" taps!
The touch screen on my JasJam responds to continuous taps even when I don't tap it. When the keyboard is slid out, the start menu keeps on popping as if the start button on screen is being tapped. When keyboard is slid inside (device is closed), the device behaves as if the OK button (the "X" on top right) is being tapped continuously. Due to this, I can't open any program. (As soon as a program is opened, the "X" button on top right is automatically clicked and I reach Home screen again!
I uploaded a video about this mal-functioning of device:
http://www.youtube.com/watch?v=YWAyRLQ01oo
I have already:
1. Alligned screen
2. Hard reset device (Left and Right softkeys + Reset button)
3. Updated ROM and hard reset device
but of no use! Please help.
Read that
it's a hw issue, had to get a replacement ...
Same problem
I seem to be having the exact same problem. When I first got it, I was able to use the phone for a couple of weeks, then all of the sudden, the screen stoped responding, but all the buttons worked. I did a hard reset, and it worked for a little while, then when bad again. At first I thought it was related to ActiveSync because it would always go bad immediately after syncing. However, even when I don't sync after a hard reset it eventually goes bad again. Today I just got it back from manufacturer - they couldn't reproduce the problem. It worked all day. Then I synced. Stupid me. Its not responding again.
There's no way out. Get a replacement.
I'm hoping that my replaced device doesn't have same issue.
same problem
I have the same exact problem. I sent back the Phone to Cingular / HTC, and they "repaired" it under warranty. I got the phone bac, and after a day's use, it went back to its old state.
Since I got this on ebay (BIG mistake), even though it was new, its having this problem.
So far i am not at ALL impressed with the 8525. Seems to me like its laden with hardware issues.
Can someone please offer insight as to what I can do?
Sorry to hear that! I had actually purchased i-mate JasJAM from Dubai. i-mate has just one service center in USA (PocketPCTechs in CA). They provided amazingly great customer service and replaced the main board. So far the problem hasn't repeated.

Hey, I am having the same problem as well. Bought my phone on December 06 from eBay seller too. Big mistake as HTC will tell you sorry your warranty is void if you did not purchase the device from the carrier (even though it was new.) I am curious how you were able to get it repaired under warranty since you too bought yours from a third party.
I did the credit card trick and it worked flawlessly for about two months and just yesterday I am back to the same problem. After today doing the credit card trick numerous times I finally got the touch screen working now but who knows for how long this time.
BTW my serial number is in the HT642Fxxxxxx if anyone else that has this problem wants to compare and post theirs.
Facing the same problems...
... I've been thinking about repalcing the display and the touchscreen. But now, considering that it is a HW issue, I can only replace these two things. If the bug is in the module above the screen (statur leds and camera) or related to the wireing at the back of the screen, it won't get rid of the problem. On the other hand, if it is a problem with the screen getting too hot, then I'm on the right track...
Has anyone tried this yet?
I'll try to call HTC on monday, maybe they know where the bug is.
So Yesterday for no reason at all my 8525's screen went white. i thought it had frozen or some thing but it didn't snap out of it. I pressed the ok button on the side and could hear noise. I decided to restart. Nothing. Did this like 7 times. Finally I let it sit without the battery for like an hour. I worked but the colors were all messed up. Reset and it worked fine. So i set my alarm went to sleep and woke this morning to an email and a white screen. Turning it on and off a couple of times did it and I was already frustrated.
Then I read on a forum about Activesync automatically opening throughout the day to try and connect. So I tweaked that to manual connections. Still the same. So I decided to take advantage of the warranty but I needed to set back my rom b/c as you already know, it voids it. Also thinking that re-flashing might get rid of whatever it was failing in. No, still the same, and now worse. As or an hour ago, my navigation pad doesn't work either. It actually works for about a second when I turn it on and then after I press anything on the pad or surrounding buttons, it's gone.
I really would like to fix it myself at least for now and use the warranty exchange at about 11 months but if theres nothing I can do, I guess I can go get a new one. Also, I don't know if it has anything to do with it, but I downloaded Google Maps to my phone yesterday on the road (through 3G) and that was the only new program installed( I think it mightve been this).
Has this happened to anyone else?
Any help would be much appreciated. I hope I explained enough for anyone to respond. Thank you in advance to anyone with anything really.
Actually if you do a search under white screen you'll find many entries. Any attempt to fix yourself will void the warranty. If you are lucky it may only be the d-pad connector that is loose. This it is possible to check yourself but if have a warranty then I suggesting using it.
Otherwise see the link to my site in my signature for dismantling and service manual guides.
Mike
Thanks. You know I think I will take advantage of the warranty sometime this week. I don't know what happened. But I'm to update my situation. It now seems as though my directional pad seems to be the problem. it glitches on and off and using it sometimes creates the fade-out to white screen. I have to let it go to standby on its own to get my screen back or play around turning it on and off for a bit.
Also, once i re-installed me ATT rom with no applications, my screen seems to be off. I have a 1/32th sliver of the bottom of the screen at the top of my touchscreen. Even in landscape it shows my scroll bar and everything. I didn't even drop it but it is now slightly skewed down. Any input on this?
I also found this website talking about the same problem having with and unorthodox solution (which I tried to no avail). Here's the link if anyone want to check this out. http://www.htcwiki.com/page/AT&T+8525+Display+issues:+Display+is+dim,+blank,+white,+has+lines,+etc.?t=anon
Anyways, I'm gonna call ATT about this see if they can help but I think I will replace, I just didn't want to so soon.
Thanks again for the quick answer.

Everything they suggest on that site you have tried I guess, the soft and hard resets etc.
I agree with you about the d-pad (directional buttons). Those with this problem often report that the d-pad or it's connector are re;lated to this issue.
Pleased you have chosen the warranty route. You see evn if you opened it up, it can work for a short while and then return again. Also push hard for replacement not repair. They may do this automatically but if not try to persuade them. The reason is that quite a few folks have reported that even after an HTC repair the problem can come back. Actually I think there may be more than one physical cause of this issue and sorting one thing does not mean it won't come back via another route.
The good news is, if you get a good one as I did on the second attempt, I never had white screen or alignment issues - despite heavy use.
Mike
Once again, thank you Mike for all your input. I will be issuing an order for replacement instead of repair. Being at work all day today I've seen that it hasn't "whited' out, if you will, but has actually kept working. Ever so often the d-pad goes but comes back in a few seconds. It may be due to the WM6 i had on it so for now i will keep the original ATT upgrade of WM5 and try to hold off on the warranty as long as I can before it expires. That way I can enjoy a healthy new 8525 longer.
For now I will keep looking around in these forums and see if there ever is a solid solution. Thanks again, and good luck with all.

Hi Guys i hope somebody who knows about capacitive touch screens can help me! I have taken my HD2 apart to fix a smashed camera lense. On removing the back cover i used a small screwdriver to prise off the back case and unclip it all round. It came off with no problem, i fixed the camera and put it back together. When i turned the device back on the touch screen isn't responding to my finger on any screen. Like i turned the touch screen off! The hard buttons still wok but nothing from the screen. Nothing looks damaged (I.e the glass isn't smashed). I seem to think i might have damaged something when prising the cover off with the screwdriver. Please, any suggestions would be really helpful!!!
Can anybody out there help with this? I am currently without a phone :-(
I have exactly the same problem, but it happened from nowhere. I didnot unscrew anything. Please Help
Check the flex cable.. this part are very delicate.
is this :

same problem
ive got the same problem, mine just stopped working, i performed a soft and hard reset, removed the battery still nothing. it worked for a moment but once locked it stopped working again, only the hard buttons.
same problem but it works on and off. basically the screen will respond until the phone is put into hibernate. the after that id have to push the phone button and end button back and forth until it responds
Same Issue independant of ROM
Same issue here.
Funny thing is it started a week or two ago randomly out of the blue.
Same scenario:
lock the phone can't get touchscreen to respond for unlock
Judging by these posts everyone started seeing this about the same time, maybe it's a software issue or background app .
Help!
I have same problem. It can work for a couple of hours or in 1-2 days then just stop responding, almost every time when in hibernate. Lets just hope it's not hardware failure.
This started happening to me this morning. Out of 50 tries, managed to unlock the phone three times only. This happened out of the blue, right after i removed my phone from the charger.
Have soft reset, hard reset, reflashed ROM, but the issue still remains.
I really really hope this is not a hardware issue.
Does anyone out there know how to solve this? My phone is virtually unusable right now...
Same problem here, I've been testing for about 2,5 months now and today I've sent mine back to HTC . I think it's a hardware problem, tried everything from hard resetting to reflashing. When I press the HTC logo and keep it pressed the screen does respond again. Conclusion: hardware problem.

You're probably right.
I've also tried everything. But kind of strange that if I lock when not on home tab it seems to work. And the screen, almost always, reacts as it should as long as I just dont' lock it.
I just started to get this issue. touch screen works fine until it hibernates. reflashed, still happens. found this in my search:
htcphones.net/htc-hd2-problems-with-touchscreen/
just got off the phone with tmo. they are sending me a new one.
Yeah, it happened to me as well. I opened a new thread like a month ago explaining the problem: http://forum.xda-developers.com/showthread.php?t=710282&styleid=15
and I contributed in another one concerning the same issue here: http://forum.xda-developers.com/showthread.php?t=708530
Summing all up, it ain't caused by a software or a ROM of some kind (at least in my case) because soft and hard resets didn't solve it nor did the flash of a stock ROM. The most probable cause is a digitizer (touchscreen) defect that appears randomly and totally out of the blue. The only thing to do in my opinion is to send the phone in for repair, which I did. It came back with a check mark on "calibrated screen" checkbox. As of now phone's working fine and I hope they solved it even though I read of other people who have had their leo's screens completely replaced..
A curious side note: htc care reset to zero my phone's call duration timers..
I'm not sure if it's the screen. In my case I think it's the connector from the screen to the motherboard, because pressing the housing seems to help.
But let's see if HTC is able to repair it, I hope they are, because the problem is so random they might not even see it
After losing functionality on my touch screen for a week, finally decided to send it in. Took the trouble to revert my HSPL to original and Stock Rom.
Repair should take about a week. Now I'm stuck with an ancient Nokia 6230i for this week. I feel so lost without my ppc. Have had one for as long as I can remember.
Hopefully the phone comes back okay...
I've had so much problem with the screen not responding so I did all backup then reflashed, hard reset to put the device back to stock. Did this during the weekend, I even fired up my old iphone 3g to have as backup phone.
All set today to go to the store and have it repared under warranty.
But since Sunday evening it works perfect. I've been testing it a lot and the screen has not stop responding even once.
This might be just temporarily but does anyone else experienced something like this?
Mine sometimes worked well for hours... days... but eventually the problem came back.
Mine died on me when I was actually out of the country (stuck in Vietnam without a phone). It would work for 5 minutes, then stop for hours. I would have to switch my phone on and off for a couple hundred times before it worked for another 5 minutes...
Got so tired of it that i sent back my HD2 for warranty repair. Expect it to be back tomorrow (or Friday at the latest). Hope there's no further problems with it.
I hate to say it, but the HD2 is known for its highly defective touchscreen. Even when it's working, a lot of people experience strange and bothering events, such as the touchscreen "touching" itself, a very high/very low screen sensitivity all of a sudden, the tilting of the screen to one of the four corners of the device and so on and so forth.
With a device so expensive one would expect it to work flawlessly. Seems to me that HTC doesn't think the way we do...
ok, I have a strange issue that I can not seem to find the answer to. Whenever my phone locks after not being used etc. When I wake it up, the touchscreen will not let me unlock. It takes me close to 50 attempts to do so. However once I actually am successful in getting it unlocked. The touchscreen works flawlessly. I have tried several different builds, all of them I have the same issue. I have done Task29 and started fresh on that front each time. I tried a couple different radios. Any suggestions?
**** man i got the same problem! i tried hard reset, rom updates, other buils but it wont go away!
plz someone help us!
Hi,I'm using BOYPPC-SHIFTPDA GINGER 2.3.3 RAM_V5 works great so far the best that I tried.After u flash android it's recommended to wait few mins until it loads everything then do a shut down - not a restart.then again u wait few mins and u do a second shut down. after that the os should work fine ,at least for me works great. if that doesn't help ,try to reinstall everything from the start..hspl radio etc.
You could just turn off the lockscreen? Get 'NoLock' from the market. That should do the business if you want.
I've got the same problem since 5 days, It started when I started using WIFI and turning off my 3G ..
you have the same problem my hd2 has....it is a hardware issue. the screen becomes unresponsive. if you still have warranty send it in for a repair. if not... repair it yourself. it's not that hard. the screen wire is probably just loose.
follow this video to take apart your hd2.
http://www.youtube.com/watch?v=cL-jnUKufC4
Sounds like a similar problem that I'm experiencing. If I wake the lockscreen with the send key instead, it works. When I boot I get exactly one shot with the end key then it locks up again. I'm able to use it with the send key, but concerned it might get worse. If anyone finds the solution please post.
I actually for the first time had this, and I know this is going to get flamed but its not the Screen thats the problem. And I think (BIG IF) that the dreaded unresponsive screen issue that we keep reading about Majority of them I think is not the screen.
I have 2 HD2s and both have worked flawlessly without any problems, but today I was playing with my test phone that doesnt get used that much and I noticed after installing a new rom that my screen after I played with it for a bit went black (sleep) and when I woke it up it wouldnt respond, first thing that crossed my mind is I just lost my digitizier, and started wondering okay why, I went as far to re-flash WinMo stock HD2 rom, same issue, so I decided its time to find out exactly whats causing this, and I found it. I wasnt going to make a post again cause I figured people would be "Not another thread about this" but I know whats causing the screen issue, at least this is my suspicision and I have temporarily fixed mine.
The problem is HARDWARE, The Culprit: THE END KEY (Red Button)! The Answer to "How or Why": The "End" key is used to turn the phone on and off or to put it in sleep mode, it is the most used key out of all 5 keys, it is used probably 7x more then all the rest, Its used for just about everything, now how does this cause the unresponsive screen? Easy, the phone lock or sleep is associated with this key, Its the only way to make the screen go off other then waiting for the time out period. Because by habit we mostly hit the end key to turn the screen off the phone automatically associates this with locking the phone, once that happens the screen becomes unresponsive because of several reasons: 1) The contact under the actual key has dirt which causes the button to stick in the down position, 2) the contact is bent which the "end" key is pressing down on the contact which is making contact with the board and causing it to be unresponsive, 3) The contact is worn. This is the reason why if you press the end key a few times (anywhere between 2-10) and then try the screen responds, this is cause your "unsticking" the key which then lets the screen respond.
Most of us when we hit the end key press to the far right to avoid hitting the back key (The button with the left arrow) which causes the end button to lean toward the right. But you can wake the phone up with the other 4 keys to the lock screen which will allow you to unlock the phone. As a temporary fix for myself, on my test phone I now make sure to press on the left side of the key to prevent this from happening, since its a test phone I'm not worried, but the real solution is to take the phone apart and clean the underside of the end button, and the actual contact with alcohol to remove the build up of dirt and whatever else. And also if the contact frame is bent to GENTLY bend the right side back up alittle to stop it from happening, or sending it to htc and letting them fix it.
We have to RE-TRAIN ourselves to start using the other keys to wake the phone up and not rely on the end key so much.
Hope this helps anyone finally why we have this problem. And if it works for you then hit the Thanks button
