Problems with screen calibration - Touch Dual, MDA Touch Plus General

Hi people!
I have a problem with the screen of my touch dual. After some hours it loses the calibration and it thinks you have pressed a bit more to the left, making impossible to close programs with the "X" and making more difficult to use the camera among other things.
I have the service manual, but I didn't find any way of readjusting the touch screen. Does anybody know how it's done?
Thanks

It's a common habit for touch screens to lose alignement.
So they made a way to re adujst it. Just go to Settings/screen then proceed with the adjustment procedures.
But if this happen too mnay often, there may be something wrong with screen itself or a faulty application

Yes, I thinks something happens with the screen, as it happens too often and sometimes when you move vertically the Nike thinks I have draw some kind of doodle
Well, I guess it needs to go to the mechanics

Touch Screen Not working.. plz help.

Hi mates yesterday i bought a used herm...with excellent condition. but when i opened any dialog. the window closed automatically. and the screen light remains always on. and touch is creating problems.
and after some time the touch screen totally stop working. i dont know what happened. al the buttons are working fine. i upgraded my t-mobile herm to its original t-mobile wm6 rom. and again the touch screen is not working. and the screen light always stay on..
so is this hardware or software problem.?
guide me if you have any clue about this..
according to my thinking.. i think some button is pressed continuesly.. but everything is working fine.. only the touch is not working.
broken digitizer for the touch screen, buy a replacement lcd/digitizer together and replace yourself, about $100Aud. Use Mike Channons site to download the service manual. Use the search function and type in "htc service manual hermes".
As for the light, you will have to use your buttons to navigate to settings>system>backlight>battery power and external power. you can select how long the backlight remains on for.
Cheers...
Hi mate thanks for your reply.. Actually the situation is that. the screen is working perfectly. all buttons are also working perfectly. but suddenly the touch feature stopped working.
that time i was just opening some menus and they closed automatically. it looks like that there is some button pressed. and the screen light never stops. it continuously remains on. all buttons are working perfectly and everything. on the touch feature is not working.
i upgraded my device with genuine shipped t-mobile wm6 rom and again it stopped at the starting screen where i have to click the screen and the device brings the window for stylus adjustment.
so i wanna ask that is this also possible that some touch drivers are corrupted or something like this.? or is this a hardware failure.?
Kind Regards
I had same problem, it was hardware. Thats why I said to change the lcd. It is theoretically possible to replace JUST the digitizer, BUT, it is a MAJOR hassle.
As for getting past the alignment stage, look up Remote Screen Alignment. Its a cab file that stores the alignment settings on your pc. You WILL have to have a friend that has the same phone so you can get their settings as you need to copy them to your pc first. You can then copy the settings to your phone so you can use it until you replace that pesky lcd...
Cheers.....
I had a similar problem with my hermes. After a lot of investigating, I found out that this is a heat related issue with the hermes. The unit will heat up an some connection somwhere gets messed up and continually registers ghost taps on the upper right corner of the screen, which causes the continual opening and closing of programs/task manager. This overloads the phone which then causes the screen to eventually become unresponsive due to excessive computing.
With my phone, it must be heat related because it will only occur during or after heavy use or overcharging. Other people have had this exact problem with the conclusion being overheating. The worse part is, there is apparently no way to fix this, replacing the screen doesn't change anything. setting your screen alignment very far left will fix the problem but then everything you tap needs to be compensated for.
Good luck, hate to be the harbinger of bad news, but it's better to know whats wrong and that you can't fix it then not know whats wrong and keep trying to fix it.
same problem here... only my hermes is overheating already after 5 minutes use...
in the morning it works and when i put it in front of the airconditioning the touchscreen also works...
somebody who has an idea where to look for a solution??

Some of the suggestions in the white screen thread/s might help. The problem is that those who have the heat related problem will find it very difficult to trace the actual fault. The heat may be causing miniscule expansions on the boards / components and connectors. The tiniest of cracks or poor connections can therefore break with the expansion.
Another theory is that rather than heat it might be a capacitor that is breaking down either over time or again through heating. Unless you are a skilled electronic engineer that is virtually impossible to check, particularly since schematics are not available.
You might just be lucky if you dismantled and re-assembled - it might just re-set a connector or adjust a board so it does not get affected in future. That would be very much a matter of luck and of course potentially the situation might be made worse!

Hi mates. I am back with some issue.. i moved my device to a repair center and he said that its a software issue. and he fixed my device without changing any rom.. i dont know how..
but again when i open some window like programs. the right scrollbar make a problem... when i move scrollbar it automatically press the top close button..i aligned my screen 3 times but same problem with right side scroll bar.
and after playing with it. the touch totally stopped.
now the thing is.all the buttons are working fine and everything is working fine. even sms and calls. but when i check sms and press my scroller button. it displays the right click menu instead of opening the sms. and the screen light is continuesly on. as something is pressed. so. i think this thing wil help. i am now trying this method to check my pc.
http://inuchanbt.blog54.fc2.com/blog-entry-99.html
check this out as well.
i will send you details soon.
might just have something lodged between the case and screen.. also to get rid of the screen alignment, cable it up and delete welcome from the startup programs and then reset it.. should get you past it so at least you can use it until you repair your screen

Display Problem: it's flickering...HELP!!!

Hi all,
I think my display has a problem of flickering: I noticed it going to "system status" window by clicking on battery, or signal icon. Here you have a gray stripped background that on my display seems to be unstable...something like flashing. I have the same impression if I look at the headers stripes of the tabs, where you find, "People", "Messages" etc...
The strange thing is that what ever I see, pictures, different windows, they all seems to be very stable, no flashing...flickering...problem.
Now I ask to myself, could it be an optical effect due to the pattern of that specific background?
I make the same answer to you all...and did somone notice the same problem?
Please answer me becouse I should have to replace it if I really have this trouble...
THX so much!

Did you try a Clear Storage followed by a Hard Reset?
@tnyynt
Thank you for your replay.
Other people suggested it to me. I've tried it right now and it had no effect, I'm still having the same problem.
BTW: Clear Storage performs by itself a HardReset after typing 1234...am I right?
I too am noticing this flickering on the top bar. I couldn't work it out. No idea what it is, but quite glad I'm not the only one with it. No idea if it is an illusion or a fault though. Can anyone else confirm?

Yes, you are right, but it's a different one than the normal Hard Reset.
Try to change brightness of the backlight, for example turn it off and check then.

thats normal. it has something to do with the refreshrate. that occours on every phone and pc monitor and so on. it always depends on what you are viewing at the momeent and often occurs when there are many very thin lines like at the top of the HD.
I have noticed no flickering at all.
@tnyynt
Do you mean I should perform a normal Hard Reset? How can I do it...I still haven't discover how to do it...
@Raziel1
It would be normal if everyone could see it on their HD, but it seems that only some terminals have this problem...Do you mean so that my HD has no problem?
THX to all!

A LCD display shouldnt flicker. It's either a hardware or software problem. Old CRT-monitors and TVs flickered because they "painted" the picture from top to bottom, and if they didnt do it fast enough it was perceived as flickering. LCD displays uses a dot matrix and shouldnt flicker regardless refreshrate.

Do you mean that I'm calling my display problem improperly or that it really can be a problem of this kind of display and so it means it is broken?
I have been noticing this exact same flickering, and couldn't decide if it was normal or not!?
but this flickering only occures when there are certain things on the screen like the thin lines of top of the home screen. its not the screen itself which is flickering. maybe it has something to do with vision and not with a technical aspect. the same thing can be seen on every screen i ever looked at. you can try it out, by taking a picture of a pc monitor at close range with high resolution. when you look at it and scroll around with zoom, it will often flicker like hell because of all the details and maybe downscaling or whatever

I havent seen the problem myself so it's hard to tell. You can often see by looking at it if its a software or hardware problem. If it's a software problem its just a certain part, for example a window titlebar, that flickers. This is usually caused by bad programming, the programmer has told the program to repaint with a certain interval even if there is no change. If it's a hardware problem the flickering usually isnt constrained to parts of the window, for example it doesnt follow the titlebar. Instead its usually diffuse parts of the screen that flickers.
@Marinese
Uhm...I'm figuring out how to test it...If I look at a picture, I can't notice the problem, and it seems to be localized on upper bars and on some particular windows I told before. If I could flash it with another ROM...but it's not HardSPL yet and I would keep it in warrenty untill my provider/seller TIM tell me what to do with it. So it could be a ROM problem too?
It would be usefull to have two of them placed side by side
and see the differences...
For me it seems to happen when the brightness is set to high, or I am in a well lit room with auto brightness enabled. With the brightness reduced I see no flickering...
Does that give any clue as to whether it is hardware or software? It seems to be dark colours that flicker.
@evilskanker
Uhm perhaps if you reduce brightness, you reduce the visibility of the problem as well...
I don't know about the dark colours...but I took a black picture and it doesn't flicker...
I have that exact same issue..
Altought I only notice it, on the upper horizontal lines on the RIGHT in TouchFlo3D.
What is the reason for that? And how to solve it?
Thanks.
I'm not sure we're talking about the same thing, but what I have is quick fluctuation in the brightness level without changes in the ambient lighting. You could call it flickering, although I would say it's not as fast as a flicker in my case. It seems to me it has something to do with the light sensor and its sensitivity. I would like to think that a ROM update will sort it, but we will have to wait and see. I'm not doing anything about yet.
@atomikpt
It's the same of mine and also try to go to "system status" window by clicking on battery, or signal icon and take look of what it happens.
@arisg
Nothing to do with your case. Consider that I desabled the light sensor and I'm using brightness to its maximum level.

Weird Touchscreen behavour - Video Doku.

Hi, I'm a big fan of the HD2 but in the last two weeks, since i own this device, i'm getting confused by some screen imput behavour that i will present you.
I want to figure out if this "screenbugs" i have to fight with every day, are normal or a hardwaredefect. To make you guys an imagine of what i mean, i uploaded some youtube videos for each bug.
1. The first one i call: The painting edge
This bug is only present if i not have installed the less sensitive CAB from this forum.
Explaination:
Many of you have notice that the glass of the screen doesn't fit exactly in the case of the device. The right bottom of the glass protrude a very little. Then i lightly press on this position, the screen notice a press on the right top...as you can see in notes on my youtube video:
Video 1: http://www.youtube.com/watch?v=c49x9vB4bzQ
------------------------------------------------------------------------
Beforce you say...my device doesn't having any of the following bugs, REMEMBER, This bugs are not present every second. Sometimes i can use the device for 30min without having some of this.
------------------------------------------------------------------------
2. The Electrocardiography
This bug, i think could be the reason for the following bugs.
Explaination: Trying to draw a straight line an you think you device will get a heart attack soon.
On the half of my second try you can see how the device suddenly works normal again.
Video: http://www.youtube.com/watch?v=t54m1dSLnV8
3. The shaking Screen
Explaination:
I have notice that some other guys have this bug too. You can see this on every scrollable screen, like opera, IE, zoomed pictures, the manila tab, startmenu...etc. etc.
Best seen on minute 0:54 in my video.
Video: http://www.youtube.com/watch?v=6hIE_wV4djs
4.The non pressed key
Explaination:
You are cofused about keyboard reaction while writing a text message? You type an "a" and getting a "t"? Than you have "the non pressed key" bug how i call it.
you have to watch on some key input where my finger is totally out of range. I don't mean the fault input next to the key i pressed...
Video: http://www.youtube.com/watch?v=_B1GiyMp_O4
----------------------------------------------------------------
There is a fifth bug i didn't get on video yet because it is very rarely.
I had have this bug only 5-6 times since i own this device, but it sucks realy hard.
I call it
5. The self-typing keyboard
Explaination:
Then i'm typing some text sometimes the keyboard begins to typing without having the finger one the touchscreen. it can be have a duration of 5-10 seconds or 20 letters/numbers.
It can also be watched, without keyboardaction. Then the screen scrolls wild in any direction without any finger on screen.
Video: http://www.youtube.com/watch?v=-fdXU8SoPTg from htcracer211
----------------------------------------------------------------
If someone can tell me if i can embed the youtube videos in this forum...
Go get a replacement, the screen is perfect. Although I admit it does not fit correctly but it is great. I only need the earpiece fix
please watch the videos before you comment anything...
...You're too much electrostatically charged...
...Or something of electrostatic is in the range of your device...
But it's like your touch panel is faulty. Get a replacement (warranty rules)
Have brought it back today...but couldn't get a replacement...no devices
tryed all your test and get no errors on screen, electro worked perfecly, keyboard keeps presing same key without leaving the range, and i cant notice any shaking effect.
So probably your screen is faulty , change your device as fast as you can matte
I have brought it already back, but it seems to be that others have all my listed bugs too. take a look at the poll results. On another forum a guy has tested the "painting edge" on 3 devices after he saw my video and all devices have this bug!!!!
Hey Guys,
I have the first 3 bugs on my HD2, too. But with BSB Tweaks 1.31 i solved the first 2 one by activating the option "Screen Sensitivity".
Hi,
If you look in the sticky thread here somewhere in the LEO section about tweaks and registry changes there is a topic on reducing the sensitivity of the screen.
I think what's happening here is the electric current in your fingers is playing havoc with the screen when your fingers are either close to or on the screen.
Let us know if this helps you.
WB
whow, that's a lot of problems for one device.
I have the "non pressed key issue" : (that's annoying as hell, typing a message is a heavy burden now) and the shakey screen. should i bring my handset back or try the tweaks... I didn't expect this from an 600€ handset

When i was made this video my finger was always with the same pressure on the touchscreen. It was not close...and not weak on screen...normal pressure. And you can see at the middle of my second try where i'm drawing lines in notes that the screen suddenly works normal.
I also wrote in my first thread, that this bug is not every second present...but then it's present its also the reason for some other input errors, like the "non pressed key" i think.
Quick question: How much pressure do you apply to the display (what is "normal"?)? Scince your display is reacting weird to pressure on the bottom right corner, any pressure might be linked to erroreous behavior. Do the shaking related errors remain when you don't press at allk?
to the OP: what ROM are you on ? have you tried 1.48 ?
I can recommende you to use screenprotector film and install cab for less sensitive.
But even without this all I had not this problem Looks like your sreen very sensitive for electrocharging and not have normal ground contact. This is way to warranty service.
lmao >.< sorry mate but get a replacement NOW!! I've never got these problems, everything works smooth and properly, sorry about that...
do u have a screen protector? i am wondering if the screen protector does anything bad to it...
You have the exact same problems I had when I first got my device, the main concern was the device having its own mind and making random key presses, even without you touching it or even being near it. I got my unit replaced and the new one works like a charm.
I noticed today that MY PERFECT SCREEN starting acting weird !!!! Its jittering !!! Damnnnn !!!!
I'm totally spooked by your video's!!!
I personally never experienced these bugs so I spend the last half our replicating your bugs.
The only thing I noticed was that Electrocardiography but I think you have your finger too flat on the screen (it has a too large surface area) because when I write on the screen as if my finger where a pencil (straight up instead of flat) the screen is working as it should!
I think you must have a faulty device. Perhaps try to flash it with 1.48 if you haven't done that already.

On iPhone with exactly the same finger it draws almost a precise straight line. This problem comes directly from HD2's screen, not from fingers, weather, humidity and so on.

HD2 oudside in the cold.

I tested out the HD2 outside in below freezing temps, and it really had a tough time registering my finger presses. It took about 5 minutes, before it could register properly... Anyone experience these issues?
Yes, and the wind keeps pressing things which makes it almost useless. I'm hoping some of the hints here on how to make it less sensitive will help but I haven't tried it yet.
I've noticed the "ghost" pressing (the screen registered a LOT of presses when my fingers were nowhere near the screen) of the screen too. I also contacted HTC support on the issue, and they said it was not a known problem.
So, again, I'd suggest that if you're experiencing issues with the screen in cold temperatures (finger touches not registering, "ghost pressing" etc.), let HTC know about it!
i got that kind of ghost typing too. pretty funny to watch but annoying when you see its deleting mails, answering sms or calls people ... will contact htc as well to let them know.
Confirmed here too. Though I thought it was caused by constant rain/snow here in Moscow, which fell directly on the screen when the ghost tapping occured.
Yeah I get the ghost tapping but only after i've been in a call and hang up, it then starts doing all sorts of things by itself normally ending up with dialling someone!! :/
I dunno about the ghost-typing but isn't it a common fact that capacitive screens don't work well with low temperatures?
That's a capacitive touch-panel "Feature" . HTC can't do anything about it (besides lowering the screen sensitivity).
edit: Umiss beat me to it lol
you can lower the screen sensitivity either by installing the new 1.48 rom or using the cab from the hints and tweaks thread in opening couple of posts. Should help.

[Q] G2 wont register touch input,

My LG G2 wont register touch input properly. It happens nearly all the time, e.g. i am typing and it works like a charm and suddenly it starts missing keys which earlier were just fine, similarly i am missing swipes everywhere like in home screen and games but they are less frequent as compared to the touch missing the input completely. I am really worried as i just spent a lot on this and where i live all the sets are imported from abroad so no warranties of any kind,
Has any one else experienced this and if yes is this a hardware problem or a software one, and above all guide me on what to do. Thanks in advance for your comments

I have this sometimes but i have realised that it is my own fault as the screen is rather large and i touch the edge of the screen with the base of my thumb, which seems to make it ignore other touch events on the screen

I also thought that i was doing something like that but then i picked it up in my hand and touched with a finger from the other hand carefully avoiding any unintended touches but still it keeps on missing taps during selections across menus and what not.
Is something causing your CPU usage to spike? If this is happening, launching an app like OS Monitor while it is happening will point out the offending app.
