I am having a recurring issue with my screen going unresponsive. It does not happen regularly, sometimes putting it in standby and back with the power key will fix it other times I have to soft reset.
I have changed ROMs a few different times and I am now using Laurentious (sp) Rom. I run task 29.
I do not think it is the rom and think it may be time for a new screen but I want to trouble shoot it to be sure before I spend the money.
Any tips or ideas?
also where can I find the .cab file for the stock task manager?
Have you already tested your HD2 without SD card?
Does it show the same behavior?
Have you tried to format your SD card after a backup (copying your needed files)?
For formating SD card I recomend SD Formatter 3.0 and a card reader.
No I havent. The SD card could be causing the Sense to be unresponsive? Ill do that and see if it helps
A not fully functional SD card can be responsible for many issues, according to many post I read.
But also there is a possibility of wrong/bad combination of (H)SPL and RADIO needed for the diferent ROMs you tested.
Installed apps and customisations can also cause problems.
And sometimes double action on the HD2 can also cause such kind of freezes. For example: powering on the HD2 at the same time you receive a SMS or call, changing/adding appointments at the same time your reminder gets active.
BTW: I don't know Laurentius26 ROMs, but according to the given information in the thread the original task manager should still be there. Have a look in windows menu or with file explorer in windows folder.
changed out to a new SD card and Josh Rom 1.8 which has been the most stable one i have used. It is still occurring. Guess it is time for an upgrade
I've had this happen to 3 different HD2's...
Seems to be somewhat of a design flaw since it keeps occurring.
The manual plastic power button sits above the area of the small flex cable that goes to the digitizer. The plastic from the power button tends to occasionally strike that flex cable depending upon the amount of push pressure to it causing the fragile flex cable to eventually short. That's why sometimes when you power it off and then power it back on again, it'll work.
I think the problem gets exacerbated when you get in the habit of cleaning your screen as I do. I hate fingerprints and always wipe the whole screen down and rub it clean with my T-shirt, but I also am not being mindful of abrasively rubbing the buttons. Sometimes I'll find myself rubbing a bit too hard and probably disturbing the buttons in a manner or direction that doesn't fair well for the flex cable.
On 2 separate occasions I was always able to remedy the problem by replacing the digitizer... and now it's happening again with a 3rd unit of mine. It's just one of those wear & tear things that stands good chance to happen with time if you're not mindful of the exact problem every time you power on or power off your screen or clean your screen.
Interesting.. I have this happening on my Desire. Your explanation makes sense

If the whole board is replaced, the digitizer gets replaced too, right? I've replaced the lcd and board of my desire, and the problem persists

I flashed a newer rom onto the phone and since, my touchscreen does not work. I have searched and seen posts that this is a "hardware" issue but since problem occured during the flashing process, I'm hoping it can be fixed.
I have seen something similar in posts about the wifi eeprom being erased. Can something like this have happened to the touchscreen controller?
So far, I have flashed various radios and various OS builds both stock and custom and it is still a no go. I can get past the alignment screen by remotely connecting to the phone and taking out some registry keys (can't remember which right now).
Using Pocket controller I can control the screen except for the screen alignment calibration which wants a pen tap.
Does anyone have any ideas other than "send it in for repair?"
adding...
Just thought I'd add that this was a second machine that I received as payment for helping out a friend. And, while I would have no problem paying to have it repaired or breaking it down to sell as parts, this issue of dying touchscreens gnaws at me as being something fixable through software.
That said, I am not a programmer so maybe I'm just simply wrong. It's an interesting problem though. Makes me wish I knew more about electronics...
I might be way off, but....check the system information for the operating system version, WM 5/6 Professional Is Touch Screen, WM 5/6 Std is not.
Thanks
Thanks for the suggestion but I'm sure the rom I flashed is a touchscreen version.
Well for what it's worth, if anyone is in the same boat, the registry key to delete will be at HKLM\Software\Microsoft\Shell\Rai\:MSWelcome
delete the entire sub key as well as the value in :MSWelecome that has welcome.exe in it.
hold the power button until the popup comes and then answer yes. when the machine reboots, it should bypass welcome and the screen calibration.
you can get Mobile Registry Editor here:
http://www.breaksoft.com/Blog/Utilities/2005/1/Mobile_Registry_Editor.aspx
this will let you access your phone's registry from the PC. Good Luck
I wouldn't think that it's the flashing process that broke ur touchscreen. Probably something else like a power surge or something. If you already tried flashing different ROMs, then it's definetely not software anymore. But of course, I could be wrong. There may be some low-level programming thingy that crapped up the connection to the touch screen.
Yeah. You're right. I was hoping that if it was a low level thing it could be fixed with software but I guess not. It was worth a shot.

Why dont you try running a very thin visiting card or anything equally thin between the housing and the screen,sometimes if a tiny partical gets lodged inbetween this problem may occur.
Touch Screen Problem
It is a hardware issue, i have had the same problem. There is no software that is going to help you mate. I restored my original t-mobile Rom sent it for repair and they exchanged the unit. Don't forget they have a manufactures warranty.
I tried everything to try to resolve the problem but with no sucess.
good luck
Update
I've narrowed the problem down to the actual touch screen. I can get the touchscreen to function correctly if I put just enough force where the mylar flex cable attaches to the touchpanel.
It is a very odd coincidence that the touchpanel died just as I was flashing from WM5 to WM6. I distinctly remember doing the pen calibration just before flashing so that I could see the screen for any prompts.
I've ordered a new touch panel and now the next challenge will be figuring out how to bond the flex cable of the touch panel to the main flex cable.
Anyone got any ideas on that?
Hi to everyone in this forum. I've recently received as a present a new toshiba folio 100, but, since I'm experiencing an annoying menu button flashing, I've thought of it as a software problem so I upgraded the folio using the foliomod1.3c and applied the rotate patch and also the 1.3c fix patch. The menu still flash with no apparent logic. I've tried to kill all applications running and it's still there. It seem to come up and down at random. I ask to all in this forum: do you believe it's a hardware issue or is a software issue? Because if it's a hardware issue I'm going to try to have a new folio from toshiba. I'm overall very pleased with the work that Dexter made to make the folio an usable machine but this flashing is driving me crazy. I use the folio basically as a portable scientific pdf reader so I need to concentrate on what I read and this flashing is really annoying. I would like very much to thank you all in this forum in advance for all the suggestion/help you could provide.

I have a request that serve All those who suffer MENU crazy button .
Is it possible to prepare application you can setting ON/OFF the MENU button
Most of the time useless button.
sometimes button jump after 10 minutes, sometimes after an hour
Usually I fix the problem by changing the settings with FolioButtons 1.1.
If you could add to FolioButtons on/off operation for menu Buttons was the best.
Hi teknoraver,
Can you add enabled/disabled menu button in foliobuttons application ?
flashing on...

I am pretty desperate about this issue, because none of the methods seem to help...
Right now the buttons work opposite- Menu button flashes mad and none of the other 3 responds...dont know how it happened
Just a thought- while the folio is booting up the menu button ALREADY flashes! I have zero understanding in there but isn't it a process that loads / starts early in the line?
I appreciate everyone's effort trying to solve this bug as it makes this handy tool a useless pile of crap.
I was wondering how many folio users are suffering of this crazy buttons madness.
Mine was crazy from the very beginning; I sent it back for repair and toshiba only did a firmware restore... Nothing changed at all!
It makes my folio almost unusable!
bye bye crazy buttons
After two weeks of testing and a complete breakdown of my folio100, I finally find the problem or just crazy buttons and freezing of the screen.
I drag a thickness in the screen in the bottom right corner of the screen to isolate the audio connector and it works better than a miracle again.
The only downside is that the screen comes out slightly from the slot but nothing really bad.
The thickness I put slightly too big or-1.4 mm I'll Demount next week to put a finer and I'll try to take pictures in passing.
Note however that the loss of waranty is innevitable.
Sorry for my bad english ;-)
I think it's a hardware issue and even a build quality issue.
If i hold my folio at the side of the buttons, i get the flashing buttons problem (even the foliobuttons app will not help), if i hold it at the other side, i've got no problems at all.
Do you have an animated background? Because I saw that some people had this issue with an animated background...
Hi Mshr73, nice first post indeed
Could you post some pictures of what you did?

I really don’t want to be too quick on this, but Dexter’s 1.4 seems to bring relief to this issue - for 2 days I have been running this mod the menu button stopped flashing!!
Any similar impressions on this?

No way pal, I guess I'm in the opposite situation. It still happens to me, and sometimes I think it even got worse... well, I can always look at crazy keys as a "special feature" that no other tablet will have!!!
I just tested without thickness under the screen, with foliomod 1.4 and after a few hours I again the problem of crazy buttons.

Well, I just finished dismantling e reassembling my Folio. Following your hint, I cut a piece of paper and put it between the audio connector and the back of the screen (yes, it was metal vs metal). I'll see whether it's gonna work or not. Crossing fingers for now.
Not that I'm so confident in leaving a piece of paper stuck right where the DC input is .
BTW, did you try with a smaller thickness? Even if this is the problem, I'm wondering whether a piece of paper would be enough or not.
thyself can someone. post pictures of before and after details?
we will be much appreciated
i didn't have the crazy buttons issue this far in 2 weeks, just my home butten needs to be pressed harder. I'm pretty sure it's hardware related, i read often that users experience it when changing from an warm room to a colder one, or in regions where its verry humid(some circuit closes maybe...). so Mshr73 is on the right way as far as i can tell.

Really sorry mate, I hope it will solved this for others too...
Anyhow, it is so disturbing, that I was already considering to send the tablet back to Toshiba...

I'm looking forward to your pictures, too... because my trial simply didn't work.
I tried with both a single piece of paper and then with 2 pieces wrapped in tape. I put these spacers between the back of the display and DC/audio connector.
In both cases, the crazy keys phenomenon started to happen after 15-20 minutes of usage.
In most cases, it starts to show when I unlock the device. As soon as I unlock it, home and menu buttons light up with no apparent reason and go crazy for 10-30 seconds.
Then, I even tried to loosen just a little the screws (I read, somewhere in the forum, of a guy who said that he solved his crazy keys and screen lag problems this way). I mean, all screws are now locked but not too tight. Well, I have to say that I don't have any screen lag anymore (I even removed the piece of paper, from the battery area, which used to solve the issue before) but crazy keys still happen. I'm going slightly mad

Well ... with a piece of paper the problem Come back.
I handed a piece of cardboard and the problem disappears.
I think that to raise the screen to solve them but I'm still not 100% sure.
So my HTC Desire Z, running CM7, has recently started acting up. There is a certain spot on my touch screen that, at random times, will act as if it's been touched. In GO SMS PRO, this occasionally lines up with a message, so I can see it press, pause, press, pause, etc. It's really annoying and screws up my usage of the phone. If I turn the screen off and then on again, it'll usually go away for a bit.
I've tried googling this issue but it's a touchy thing to phrase. (hehe, "touchy", I didn't even mean to do that!)
Does anybody know how I can find out what is causing this and/or how to fix it?
tl;dr: touch screen is "pressing" a specific spot at random

Its not rocket science is it bro ......... i figure you already can see the writing on the wall ...... sounds like your digitiser is on its way out. Quite a common issue on HTC's the capacitive touch screens just wear out.
My advice is backup, do a factory reset. see if problem persists, if so maybe try a different ROM (just for the sake of testing) see if problem persists.
If so you know its a hardware fault.
The good news is its really pretty easy to replace a digitiser in a Desire Z, I bought my own Desire Z 2nd hand with a dodgy digitiser (for about half its 2nd hand value) and replaced the digitiser in about 3 hours (that was going very slowly and being very careful)
Here is a link to the disassembly guides i used

Desire Z is one of the easiest phones i have ever worked on HTC obviously designed it to be repairable, almost everything is held by screws. So you don't have to 'unclip' loads of weak plastic crap.
All you need is to take it sloooooooowly and NEVER use much force, better to take an hour to do a job that should take 10mins than to rush or get impatient and break sh*t.
Good luck

Update: So the "pressing" isn't really happening any more, but now there's a dead area that takes up an entire horizontal portion of the screen. I tested it out using a TouchTest app (picture 1) and the cut shows the dead portion. However, I tried it again later, and the dead portion moved up! I'm very confused, haha
{ Disclaimer: the following text is my view about this problem. I'm not in any way responsible for any damage }
As there is very little info known about this phenomena I will try to explain it. I learned a lot of disassembly guides and by visualizing it (settings-development-show touches)
Ghost touch is a strange phenomena of various types and is due to a hardware fault between the mainboard connector and digitizer screen, I'm therefore trying to clarify it by categorizing them in three groups:
1. Small; Screen is unresponsive. 1 lock/unlock and it works again. Almost perfect. No need to replace screen. Most common.
2. Large; Same as 1, and often up to 5 touches and the touches are often moving/pressing parts of the screen. This can become a very frustrating period. Messaging apps and settings can be messed up by these touches. Often a lock/unlock will fix this temporary. A full screen replacement is recommended
3. Unworkable; Same as 2, and the lower and upper part are not working anymore. Notfications bar can not be pulled down anymore, typing become a nuisance and it not possible anymore and you curse your phone. Also it is not even possible to insert your pin, unlock your phone etcetera. This problem will not be fixed by a restart/reset or lock/unlock. A full screen replacement is essential.
Many people say this can be fixed by software settings, however this is a hardware fault. I tried many different roms and I encountered at all of them. The only fix that can be done to fix this is replacing of the full screen as it is not possible to apply/remove your digitizer.
For a long time I thought it was due to the degrading digitizer or something, in fact it is probably the connection between the and the mainboard. The screen has two digitizers: One for the touchscreen and one for the home/settings/back/search buttons. For some reason this last one did not cause any trouble. The first one has a flex cable from the upper part of the screen leading toward a small hole and heading to the mainboard. The problem will probably reside in the part between the digitizer and the small hole. Here, just above the screen, the flex cable is folded 180 degrees. This fold will cause the problem as it is very sensitive. Mine has a very small damaged part, the copper parts are visible. The cause of this is due to the rubbing of the bezel just under the speaker.
How to fix it?
Buy a new screen including digitizer (often HTC & Sprint branded) and make sure you protect this part as much as you can.
EDIT:
I re-inserted my old LCD display with a bit of tape around the damaged part. Since then I haven't had any ghost touches.
Mine was ghost touching so bad it was completely unusable for a few days. I was thiiiiiiis close to buying a new phone, then one day it just stopped and hasn't done it again since. Very strange. Anyhow, I will be replacing it with an s4 when the price comes down to $100 for us SERO users.
Ghost touch
Nice explanation, and nice 3 lvl sorting but, tell me one thing... I have experience with lvl 1 and 2 (two different phones) and for both of them simple ROM change / reinstall helped to solve this problem.
For ex. I had JB [ROOTBOX] ROM since the last week.. ghost touch problems were getting worse and worse with each new day yet lock/unlock still worked quite well.
I decided to test new JB MIUI ROM and like a magic touch my ghost friend is gone since than, but I am afraid he will return more powerfull than ever... oops that is a different story. However my phone is now working fine ... no ghosts detected.
So please don't tell me that this problem is only mechanical problem ( due to ROM change / reinstall worked multiple times). Actually I am pretty sure that is software problem which is supported by hardware hitches.
My friends "ghost story" is pretty similar.. but he reinstalled back original ICS ROM.
PS: I don't want to start flame war with this reply. It is just mix of my experience and opinions.
Bought a new european lg v30+ , the First 6 months have been trouble free, after that i noticed the phone selecting random things while scrolling through chrome or even settings (Also happens in safemode), it seems like it's lagging, i have 50 apps in total including the stock ones, no games.
If i hold de task switch button for example it starts rapidly switching apps like i'm tapping really really quickly.
Sometimes while typing it selects letters multiple times instead of once. I assume if it was a faulty digitizer this would happen all the time? Phone has always been in a rugged case, no screenprotector. It's running official android 8 which i upgraded through lg bridge. Already tried factory reset, did not help fix this issue
If you enable Developer Mode and access those settings you can enable the phone to show you touches. This will confirm the phantom touches in apps is coming from the operating system.
My guess is that you have some crud/dirt around the edge of the screen. Take it out of the case and give it a good clean with isopropyl alchohol, and run your fingernail along the edge with a tissue. I certainly have had similar behaviour at times on various phones if the screen gets a a bit grimy and resolved it with a good clean
Other than that is probably a faulty digitiser and might need to be replaced.

I did enable show touches in developer mode, sometimes i saw the phone suddenly not registering my finger while i never lifted it off the screen. I will try to give it a good clean. Screenshot i posted below should have been 1 continuously line, that's what the phone registers when it 'freaks' out. Could this be linked to the amount of ram available?
