I have had a problem with my touchcreen for 2 weeks now. The touchscreen all of a sudden stopped working, i tried all the suggestions on the wiki to re-align the screen. It didn't work. I then replaced the touch screen and it still did not work. My hermes isn't in warranty so i had no choice but to get it fixed myself. I then rang HTC and they told me it was a software fault and they have no solutions as of yet but are looking into it.
I have seen, looking through the forums that many of you have the same problem as me... do any of you think HTC will be true to there word and find a solution, or will we all have to live with smartphones now?

Quite frankly I don't believe HTC's answer. Yes some of these cases maybe software related in which case a hard reset should fix it. If it doesn't then the device is faulty and should be replaced under warranty if possible.
However most cases in my experience are neither hardware nor software!!!!! They are related to the pressure put on the screen/digitizer by the case/bezel and are often intermittent, apparent when device is warm or in a few cases permanent alignment or no screen response is shown. Many report random or even predictable responses such as start menu opening and applications closing despite no user taps on the screen.
I have made several posts telling users not to spend money buying new screens as in the majority of cases there is no fault with the screen or indeed with the software but rather a proportion of cases put pressure on the touch sensitive screen.
I would further point out that a software issue would be apparent for all those with that model - this is not the case.

I had this problem last week and I solved it realigned the screen. Now, everything is fine. Fortunately.
I think you can soft-reset the HERMES to check if it will work properly, or hard reset.
Did you unlock your screen?
Hello
In some cases, the problem is in a broken conexion under the main processor of the PDA (no phone processor). In other cases, you can see if have a dent in a surface of font case, around of the display. It causes a false measurement in the touch screen system.
Please, you excuse my bad quality for English.

If it dosen't work, maybe you can try flashing with other ROMs.
Hi, i haved this probrem, i solved it pushing arround the screen, it seen thad in my case it was a probren related with internal contac of the sceen.
(sorry for the bad english...)
Yesterday I dropped my Touch HD. I was sitting down, and it was in the pouch, so I thought there wasn't any damage done. The phone seemed to work like it should. However this morning I noticed that in Opera my screen wouldn't rotate. So I tried different programs like the HTC Album, and the G-Sensor calibration. Neither of those give any sign of life, GSen doesn't work either.
I did a soft-reset, I don't want to hard-reset just now...
I didn't find anything using the search but did anyone else have (or hear of) this problem? Can I assume my G-Sensor is dead? I have warranty so its not that big of a deal, but still...
http://forum.xda-developers.com/showthread.php?t=457985&highlight=sensor
give it a good shake, might be that the part that moves in the gsensor could have gotten stuck
Thanks for the link Juggler (wonder why I couldn't find it), however the solutions there didn't help me. I tried altering the settings in Advance Config Tool like in the other topic, but its still not working (didn't think it was a software problem anyway, but I'll try everything that might help...).
I tried shaking, tapping, and hitting the phone as hard as i dared to (don't want to brake it even more ), with no success.
The people in the other topic also had one of the bubbles in the calibration tool stuck to the left, hitting it on that side got the sensor unstuck. However both of my bubbles in the calibration tool remain dead center, so it looks like the phone isn't receiving any input from the accelerometer at all Its either broken or disconnected then.
I guess I'll have to send it back, unless anyone here has a miracle solution?
The problem seems to be solved... I have hit the phone a lot harder then I dared to do last time, en it's working again
I think it's a strange weakness though, my previous phones have had much more to endure, so I hope this is not a sign for the durability of the Touch HD in general... Especially since I'm not the only one with this problem.
Anyway, problem solved. Thanks for the help!
Hi guys,
Please download and watch the 2 videos i made and try to reproduce it if you can.
On the keyboard i'm """literally barelly/not touching"""" the screen.
On notes, drawing that slowly i get that. Already tested on another unit and had the same problem...just wanted to see if i'm not alone here..
This is unpleasant... If you already noticed the problem please do coment if you fix it or...
I did calibrate the screen, messed with reg settings but nothing changed.
I'm just trying to see if this is software related or hardware related.
Thank you !!

Very strage...
about the second video, what happens if you move the finger rapidly on the left portion of the screen?... are the results identical to the results of the right portion (as you did in the beginning of this video)?...
if you encountered this with another device, it's probably reparable via software upgrade... I hope...
unfortunatly it does the same thing be it left or right
on both devices.
It's an alignment problem. Try realigning the screen, touching as lightly as possible on the crosses and not moving your finger until the cross moves. No worries. Mine did the same stock and never after I realigned.
Drawing
I was resigned to living without the ability to draw on my HD2 but I just tried drawing in notes and was pleasantly surprised that it works quite well, even with my fat fingers.
solved?
was this solved by the realignment?
no, it helps a bit, but still not 100%. Whatever I do, I can always make the keyboard go crazy. The touchscreen needs a better driver.
Right, since this is such a significant impairment (and some users don't seem to experience it), I decided to create a separate thread for it:
If anyone finds out how to properly CALIBRATE the touchscreen on Froyo on Blackstone, please post it here.
So far, the "msmts_calib=0x395.0x3c9.0x79.0x77" results in random keys etc being pressed on the left hand side of the screen.
Thanks

well, there is a bigger problem as the calibration part ...
in froyo it seems to be, that the calibration willb e done automatical and it is not necc. to do anything extra...
but the module/driver for touchscreen is buggy ...
better for testing is the app dotty (can be downloaded from market).
there you'll see, that if you press via finger middle botton, that it jumps on screen touch to left botton - only sometimes ......and with this bug it is almost not possible to use the phone via fingers ...
my boot paramter for calibration is: msmts_calib=0x395.0x3c9.0x79.0x77
but as told above ... the problem is the touchscreen doesn't work correct if using finger ...
if you use the stylus, then it is working, so i think it is a bug, that if the touchscreen driver is getting multiple zones on touching the display, then something strange happen, and then it add an extra point on the left side, which makes using keyboard (SIP) almost impossible.
the only questions would be: does this bug also happenon 2.1 ?
because it it is there working, then we can try to implement the driver from 2.1.

Slow down...
Slow down guys...
For 99% of users the calibration works fine, you're in the minority experience tolerance issues.
Touchscreens drift over time, and with heat fluctuations (quite dramatic ones only) etc.
You guys are just unlucky and have devices that have clearly drifted by some amount....
Now, there ARE instructions floating around about how to fix calibration issues, but they aren't on the Blackstone thread, they are elsewhere and I can't recall quite where, but they DO exist.
When it comes to used a finger instead of a stylus, here you just have to live with the differences between a resistive and capacitive touchscreen. Resistive is the one used on Blackstone and most other touchscreens older than 18 months old, whilst never devices tend to have capacitive screens.
What's the difference?
Resistive need physical pressure against the screen, but can be highly accurate in ONE position. You can use these screens with or without a stylus, so can be good for handwriting recognition etc.
Capacitive need NO physical pressure against the screen, but are less accurate.
However they can detect multiple presses at the same time in different parts of the screen.
You can't easy use these screens with a normal stylus and so they aren't ideal for handwriting recognition or fine detail work.
When it comes to using your finger on resistive screen, a lot of accuracy is lost... you're just pressing a large area of the screen and the screen can only deduce ONE point under your finger. This can lead to inaccuracy and wrong buttons being pressed with a UI that has tiny icons and controls.
If your touch calibration is ALSO out, then things get worse still.
Now, before any techies get too techy, there ARE some 'smart' techniques for trying to have multi-touch on resistive displays, but we will no go into that here, and they are generally 'hacks' that don't work in all scenarios.
You guys just need to get your displays recalibrated... that should cure 95% of all your problems, and the remaining 5% are just the stuff we all face... like no multitouch, pinch to zoom etc
It's definitely wrong to give the impressions that XDAndroid releases simply don't work correctly with touch screen. That's very misleading indeed.
i too have issues with touch screen accuracy (both 2.1a and 2.2 v1.0)
80% of the presses are fine, but the other 20% xdandroid would place my finger about 1" to the right, slightly down of when i first contact the screen, and then work out where i've actually pressed a fraction of second later, translating it into a swipe etc.
the touchscreen tool in the debug area proves this fact.
WM is perfect.
weirdly, it seems not to occur at all/noticably less using the stylus. maybe something todo with pressure/contact area?
i do think the OP has a valid issue tbh.

Thanks for the info.
First, I didn't mean to mislead anyone. I just noticed increased inquiries about this issue and I wasn't aware of the 99% of users having it perfectly working...is this a fact btw?
Besides, I am aware of the different types of displays but obviously, pinch zoom etc are not exactly the main concern, we are just looking to use the phone with our fingers mate!
I agree - I have been using the phone for many months running WM and I had no issue, whatsoever. I am not much of a techie but you are still referring to the software calibration, correct?
Thanks for sharing some valuable info again. I would love to see those instruction on how to do this calibration as without it and along with much of resentment to use stylus, it pretty much makes the phone running Froyo useless )

But windows mobile typically makes you calibrate your screen when you reflash a ROM, making the calibration specific to your device.
It's also not clear where the calibration info is stored, other than the registry it MAY be stored in E2, or some flash area somewhere. Regardless, it usually forces you to recalibrate (some custom ROMs skip this).
The XDAndroid chaps deemed to 'auto configure' Blackstone calibration for some reason, and this is the most probable reason why folks are having issues.
As for 99%, hummm well, just my releases alone have over 20,000 downloads, and my stuffs one of the lesser used!... yes, some folks have calibration issues, but the majority aren't reporting any... I've maybe seen/heard 20 folks with the issue... that's not too many all in all across all the various releases. AND, some of those guys were also the types of guys saying "this sucks, the battery lasts 2 hours".... as if we didn't all know that ;-)
There was a calibration tool floating around somewhere, plus, those values CAN be edited to suit your device, so there is some home!
Wow, I thought I was one of the only people that had the calibration issue. X_X It's what caused me not to use XDAndroid as much. =(
Anyone have any idea what the calibration tool was? I tried searching calibrate and calibration but no tool was mentioned in the Blackstone droid threads.
PS. I have no idea on how to change the calibration values... =/ When I open up the ts_calibration it shows up as blank. When I open up the startup.txt ("msmts_calib=0x395.0x3c9.0x79.0x77") I do not know exactly what the values affect.
Update:
I tried using the stylus but it currently has the same problem as if I was just using my finger... Does that mean that my touch screen is going out on me? =(
I have a problem too with touch screen calibration.....I guess i'm 1% of users...
im curious as to how maany others have this issue - seems theres a few coming out of the woodwork now
im sure the XDAndroid FAQ or the release thread says the devs are aware of almost all issues so dont bother reporting them (or something to that effect), yet i havent seen anyone mention touchscreen issues upto this thread.
does anyone see a need for a bugtracker for the XDAndroid, or are the forums sufficient? to me, forums seem a bit 'unofficial' with reguard to bugs - maybe an official bug tracker (specific to the android project) would help everyone to see what people are experiencing and numbers involved.
i must say i am only a user, so i dont see or get involved in the development side so maybe this thing already exists in closed circles.
to put it another way, each phone has their own android subforum so it must take the devs alot of time to collate info. bug tracker could be a better way to manage this?
I have the same problem, since 1.6... i touch the screen and is like i touched 1cm outside the screen on the left for 0.001 seconds, so is extremly difficult to type without stylus.
with the stylus is much better but still not good
Ps. i remember the first version of android working on blackstone (1.5 i think) was working good, and the touch screen was fine

I would dig up that version along with calib code in the startup txt file then!
well, i've put the idea forward in the main android subforum here.
it would certainly be useful from a user side perspective to see progress and known issues. fingers crossed
edit: and when did i move to 'Senior member'!!?
I experience similar issues with 2.2, didn't notice it to the same extent in 2.1. When I type on the on screen keyboard, pretty often i get an added button press detected off to the left (about 2 - 3 cm). The problem does occur a lot less when using the stylus instead of the finger.
This is NOT likely to be a calibration problem, as in that case all presses would be off consistently (e.g. always half a centimeter in the wrong direction or something like that).
It looks as if the Touchscreen sends some "incorrect" data that WM filters as too short of a press or whatever and that is affecting some users.
mmm, questionable.
Calibration is as far as I'm concerned done each time, individually with new system (ROM) unless using a saved one from previous attempt install (my Froyo case).
To my understanding of the matter, wrong calibration doesn't necessarily have to mean your display is "shifted" 2cm to the left or so. Simply, it just doesn't work properly i.e. you have the same problem as all other people in this thread.
Maybe reading TheBrilliantMistake's post about different types of screens earlier would help you understand...
after all, we need that calibration tutorial/tip which is allegedly somewhere around here...

Cant we set android to ignore the first 0.1seconds of a pression on the screen?

ah - finally
now you got it - this is exact the problem what i want to tell everybody ..., and i'm sure, that this happen, because the touch screen driver doesn't calculate correct the position when a bigger range (like touch from a finger) is touched. This doesn't happen, when stylus is used ...
to remove the first 0,1 sec or something ... don't think, that this would help
...on the other hand ... which module is responsible for touch screen ?
Just for a start the background of calibration (it's on security risks with touchscreen based voting machines but the principle is obviously the same) - http://vote.nist.gov/threats/papers/touchscreencalib.pdf
I believe TheBrilliantMistake in this case thought we'd sometimes hit adjacent buttons. But fact is, it always does trigger to the left and in addition to the correct press being detected, so well there's something else to this one.
Guess it will be ironed out eventually as it's a lot less common in 2.1. But it's annoying to the point of making texting a real pain in 2.2.

does it means, that under 2.1 there is no such kind of "touchscreen bug with finger" ?, because then we can take a look to the modules - maybe we can compare the difference to 2.1 ...
I didn't experience it there but I have to admit that I didn't use 2.1 for too long. Maybe it's a speed issue with 2.1 being more optimized and polished then 2.2 which leads to it occuring on a less frequent basis.
Due to the known problems with powersafe modes not being supported yet in XDAndroid I'm currently mostly running WM6.5 but I'm looking forward to the advancements with XDAndroid, great project.
Add 2 more devices to the 1%.
I'm experience the same issue. My friend which has a newer Blackstone than me let me put my XDAndroid mSD card into his phone and there goes the same issue.
Tested with some drawing applications, here is what i experienced:
Just like others stated before most of the times when the bug occurs I get a line starting like 2 cm to the left of my finger (and a little lower) and ending under my finger. It's like I've been dragging my finger across the screen for 2 cm. Sometimes it goes as far as the left side of the screen.
Since this is inconsistent I doubt it's a calibration issue. I must assume it's the driver. But I might be wrong.
Anyway I believe a lot more people than 1% are experiencing the issue but they aren't posting about it since they believe it's a known issue.
Hi all,
My trusty blackstone has begin letting me down and I don't know if flashing a new rom will help, or if it is something physical that is breaking / broken. I'm using the Stonehenge ROM with CHT and everything has been fine for months.
Recently the touch screen allignment just seems to 'wander' sometimes just a little, other times quite a lot (so much that using the fake hardware buttons at the bottom of the phone, brings up the start menu). This means that intermittently I cannot answer calls, and typing a message on the SIP is an absolute nightmare!
The start menu icons do not seem to be as affected as the home screen and CHT, and I can quite easily get to the phone settings and recalibrate the screen - this will help for a short while but the alignment drifts again.
Restarting the phone has a temporary positive effect but it doesn't last.
Anyone else experienced this?
I have exactly the same problem.
Dissembled the whole device, blown some hot air but didn't help. Seems it's a HW fault. But I have a doubt whether the problem is in digitizer or in control board.
It's definitely one of the more frustrating problems that I've ever had with the phone.
I might try flash a new ROM then give up if that doesn't work. At least I won't be tempted to disassemble as it has already been tried, tbh I'd have just tried the tin of compressed air too, I don't trust my soldering skills for tiny electronics.
It is getting progressively worse, the touch area of the screen has slipped so low now that I can't use half the screen.
