Problems with my Touchscreen!

Can anyone help me please !
I've got some problems with my touchscreen.
So.. it works perfectly but time after time (approx. 2-3 hours) the touchscreen adjust itself! This means, when I touch the mini keyboard for a word (e.g. "e") the "r" is highlighted! For a better view I took ScummVM to watch with the cross and it seems to me, like there is a failure in the touchscreen!
Has anybody the same problem?
How can I fix it ?!?!?
I send it back where I bought it, but the result is the same as before!
Thanks!!!

Hi mt2002,
Does re-aligning your screen (settings->system->screen) help, or does this only lasts for a few hours too?
Think you've got to send it back again, they didn't solve your problem in the first place and this feels to me like a warranty issue.

I have the same problem, and I cannot fix it, too.

Touch screen issues
Yeh had the same issue. Just seems ot be fairly randomm for me.

Hi, same problem here. I tested with a hard reset, another Rom flashing and instaling and desinstalling programs. The best thing I discover is that software like batti (add a line in the top of the screen with battery %) and vbar (task manager) accelerate the alignment problems.
I had ROM 1.11 and now 1.12 (no 1.13 in spanish language) and know I have less problems than before.
Another thing I realized is that the dealignment is not the same in all the screen: sometimes is ok in the upper part and a little bad on the bottom one and sometimes is the other way.
Anyway now I can work with it with no more than 2 realigments a day, depending on the use.
Hasta luego!

I am facing the same problem. Reinstalled the OS with version 1.11, and then 1.12 but both doesn't help.
After hard reset or reinstallation, the screen is ok for a while. But then disalignment happens. Re-aligning works for a while, and then sucks.
I think there is a problem with the hardware, not the softwares.
Do you think?

Try pressing on the back of the unit with your other hand,
(Holding edges with thumb and other fingers and pressing your first finger on the back)
While using the screen.
Also try making a new note and just drawing a grid pattern (Like a huge tic-tac-toe board)

Touchscreen doesnt work?

Since 2 weeks the bottom 1.5cm of my touchscreen doesn't work
anymore.
I assume this isn't software related? So i will take it back to the shop for
reparation.
Because i have a custom rom installed, will this be a problem for my garantuee?
Or do i have to install back the official rom? And wich one?
Kind Regards,
Dieter

Same problem here...
After upgrade to 2.1 (VillainRom 3.4) the touch screen doesn't work as before. It seem that the bottom of the screen has some problems, the keyboard is less receptive...
Jef

I to had it after an upgrade to 2.1

Dont think its rom related...
I am on the official update from late last year (1.6? 1.5?)
Its been fine until about feb/march this year
Asked the tmobile store how long itd take to send it in. They reckon 2 weeks. wtf?
And they didnt have any loan phones.
Why does it take forever to get anything done in the uk?
Anyway... I reckon its the hardware. Must be a loose connection inside between the touchscreen or something.
Sometimes the bottom of the screen is not working... sometimes wherever I touch the screen it thinks im touching the bottom but on the same coordinate on the x axis... sometimes it just goes completely nuts as if I am sliding my finger side by side along the bottom of the screen (when I am not even touching the phone). Sometimes switching it off and on helps... sometimes it doesnt...
Initially it was only happening occasionally... but it gets worse... now I can expect it to happen every third time I try and use the phone for anything.

Same here , it's annoying. It was never there for 6 months but since Feb 2010 , i've been having this touch screen problems.
Since the upgrades for 2.1 started coming in , right after modaco custom rom 3.0 .

i had this problem. bottom of the screen was unresponsive unless i put my full thumb on it (not so good for typing) and sometimes it thought i was only touching the bottom. paid $115 to get the screen replaced. works a charm now.

[Q] G2 Screen Issues

Hello,
I've been having touch screen issues lately, since i rooted and switched to CM 6.1 a couple of weeks ago. The screen will work perfectly for a little while, but will inevitably stop responding. I'm using launcherpro, though i don't believe that's the issue- it happens regardless of which launcher I'm running (I've tried others and experienced the same issue. The optical scroll pad will still "sort of" work- better than the screen (which will respond to the occasional touch after the problem begins, but barely does). If I reboot, the problem will usually go away for a while again, but will recur. I wind up needing to fix the issue once or twice a day. I don't think it's a hardware problem because the reset fixes it, so I assume it is then software. Also, i don't remember having this problem with the stock rom. Has anyone else experienced this, or does anyone have any ideas?
Thanks!

Dunno how useful this will be, but have you tried reflashing CM?

Same problem here. But I've noticed sometimes if I'm using the phone not in my hand (on car dock or just on table) this problem seems to happen more...but when I hold it in my palm then works fine.
But sometimes it just becomes unresponsive. Am running virtous's rom on my g2. But I can remember having the same issue when running cm on my g1 days too. Reboot always fixed it, just gets annoying.
Anyone have fixes to this? Thanks!!

I personally use GV 7 or sparksmod and. Never had a problem, these are the best roms I think for this phone.

Been having this exact problem for weeks now. And I believe it is a hardware problem, probably some sort of short in one of the ribbon cables or the digitizer itself. Occasionally, actually 85% of the time I'd try to open an apparently and the phone would act if I held my finger down and then the apparently icon gets selected...very annoying cus it happens over and over a couple times, all I can do is keep trying until it does what its supposed to. Also with the on screen keyboard when I'm texting it'll act like I'm holding down on one of the letters and keeps bringing up the special characters to that letter...or ill tap delete to delete a spelling error and it'll end up holding it down and deleting my whole damn text and I can't stop it.
At first when this first started happening I could simply tap the screen and it would stop the crap it was doing and work fine. As time went on I noticed I kept having to hit it harder and harder for it to correct it. Wellllll guess what? Last night it was acting up horribly and I slammed my closed hand against it while it was on the desk and it cracked the LCD screen and now the phone is completely useless, even though the outer touchscreen is perfectly fine.
The restarting of the phone also usually fixed it for me as well but only for a few minutes.. which also makes me think its a short because after the phone is turned off whatever part is shorting out, that circuit is closed and just takes time until you press on the screen in whatever spot to cause the two parts to touch and create the short all over again.
Anyways that's my story...just don't get angry and slam down on the screen lol. This is my 2nd G2 and I'm tired of it, probably just going to get a nexus s or just go back to the nexus one, atleast it was reliable.

if you open the battery cover u can see that there are connectors that closes the whole circuit, so when u are holding the phone the back cover works like a grounding area that makes the screen responce to your touch. Acapacitive screen works like this: when you touch in any area on the screen, you simply are breaking the electrical field that the screen has, the screen "feels" where u break it and tells the operating system.
the electrical field depends on the human body a bit to make the circuit complete, so when u touch the metal parts of the phone, the screen works like it is designed.

Unresponsive touch screen :(

The top part of my phone does not respond to touch anymore... it is impossible to bring down the notification bar... and once in a while the whole screen goes unresponsive.. tried factory reset but still the same problem..

am having the same problem since 2 days back
after reading some of the posts i found that the Digitizer For HTC G6 Legend A6363 should be replaced with new one i ordered mine from ebay
ebay.com/sch/i.html?_from=R40&_trksid=p5039.m570.l1313&_nkw=Digitizer+For+HTC+G6+Legend+A6363&_sacat=See-All-Categories
waiting for the item to be delivered

I've also got a touchscreen issue: the area of the notification power widgets is unresponsive... the rest of the screen works fine, but I don't know for how long :/

Do you have widgetlocker, by any chance ?
Or a lockscreen replacement which disable the notification bar during the "slide to unlock" state ?

I didn't know there was such thing as widgetlocker. I use CM7 latest nightly, never seen that thing.

I also facing this problem from last 2 weeks and i also think this is digitizer problem. If anyone else found the solution else changing the digitizer, then please post.
This is beautiful phone but htc added a poor quality things in it, due to which many users facing such problems.

Nah.. I dont think its because of widget locker.. its the digitizer..

well that's a shame, gotta buy a new digitizer on ebay after just over 1 year of use...

I know.. this sucks... Im planning to upgrade though.. Any of u guys have any suggestion?

Depends on your carrier if you want suggestions for an upgrade.
...but that would drive the post off-topic.

I have the same problem. my screen doesnt work anymore because some water got in from the grill above the screen :S
should I try to take apart and dry off or shall I buy a new digitizer directly?

I think it may be a good idea to try disconnecting your digitizer and reconnect it as it just might be helping. I did it on my girlfriends legend and it has been working perfectly ever since. Maybe a good idea to at least try that before buying a new one. So i guess it could be in the connector to? At least this worked for me.

My touch screen dosent work at times. but after rebooting the phone the problem becomes solved. But the problem comes again after a week or so. Any suggestions guys??

I also have this problem, but if I wait a couple of minutes the touchscreen
becomes responsive again. Half of the screen works when it's unresponsive (right half of the notification bar and down). It's quite annoying but I cannot afford a new phone at the moment.
I'm also wondering if this might be temperature related, this problem reoccurred very often during the summer but stopped during the winter. But now (spring) it's back again.

My problem got worse and the phone became totally unresponsive, changed it, got a new phone.

exact same problem here, mine works when it feels like working, totally random, I simply can't understand why, I doubt it's the temperature... I think its in the device theres something wrong, I smack it numerous time and it works right after a big smack on the screen, or rub your whole hands on the screen, also, the angle you are holding the phone affects this problem, if none of these work, a phone restart always makes it work at the beginning. Oh boy did my phone took and taking much beating... oh well, I wish I could permanatly fixed the problem here, as I was thinking of handing the phone to my brother when I upgrade, I'm using CM 6.1.

I still recommend the same thing that i posted earlier here, her screen still works perfect.

I had the same problem few months ago. The problem is with the touch digitizer. I bought a digitizer on ebay and replaced it myself. After that my phone has been working fine. Its not that hard to replace it if you have a small knowledge about hardware.

I use to get that unresponsive screen issue only in the summertime, plus it gets worse if I add humidity (read: sweat). I just need to give it some time then to dry off/ cool down outside my pocket, and it's all fine again.

Random Clicks

Hello Everyone!
Long time now, i have an issue with the Touchscreen of my MB526. From time to time it generates random clicks ... if i then send it to standby and wake it up, everything is fine again. I thought it may be a hardware-problem or a problem with the custom roms around, but when i posted this issue today on the Defy-Facebook-Group, i found someone with the same issue on the stock unrooted 231 Rom (BL7). The Same BL as mine ...
So may be, that there is an unidentified bug in our mobiles? may be some driver problem? Or is it an hardware-issue like the speaker of the MB525, that affects more users?
Maybe some of the Rom-Devs could try to find something related to the Wake-Up precedure what resets the touchscreen and clears this issue?
We need some help here ...
EDIT: There is now one more on the Facebook-Group with the same issue but on a MB525 ... so it's Defy in general and not only Defy+ ...

The same problem here
First of all thanks for addressing this problem. I thought i was the only one.
Ok so I'm currently on W.R.1.7, Defy mb525
And i experience the same problem. random touches and to reset it i have to lock my screen and switch it on again.
I haven't (and wont do till 5 more months) tried this on other roms. but it always starts after 1 week of installing wr 1.7.
I flashed the rom again thinking that it will solve the problems (this and batterry drops) it did but after a week it was back!
:crying:

Had that just today, for the first time.
Was playing Hill Climb Racing, when suddenly the gas pedal (on screen touch area) got stuck, then flickered irregularily 3 or 4 times a second for like 15 seconds. My defy didn't register the back button or the home button during that time. Switching off and on helped. It happened again like a minute later, but not as long. Didn't happen again since then, but if it does in another app I'll report back.
There is no demo function in Hill Climb Racer as far as I know, so the pressed gas pedal could only have originated from the touchsceen / driver side, not from faulty code in the game.

My Defy, MB525 (Green), has 2 years old and I have this issue since always, I didn´t use my warranty because I've rooted since i bought it, but just happens sometimes (the same issue on stock 2.1, stock 2.2, MIUI, CM7, CM9, CM10...).

OK, so this themes to be an issue that affects more than just a few users ...
there was a guy in the facebook group, that reported, that he had this issue to, but it stoped since he used a screen protector ... so this may solve this issue ... but i think this is not all ... The screen is (for sure) not designed to be only useable with an screen protector
and because of the Lockscreen / Wake up solve, this is not happening due to dirt on the display or something i think ...
would be nice, if some dev could answer this post, so we would know, that we are not alone and may maybe get some help in some time ...

@ MadMooney ... i also found this annoying in Hill Climb Racing It's exactly the gas-Pedal that is "locked" then .. bit it happend in other apps (by writing an sms fpr example) to ... so it may be some fingerpoint that we both have exactly the same issue with the same game and the same affected screen area ...

Even i use a screen protector (Amzer one) but that doesn't help in solving the ghostly touch problem..
Its definitely a software issue

I have the same problem with mine, i thought it was because since 6 months back i totally cracked my screen and havent changed it because it still works as it should except looking terrible. What i have noticed thou is that i can absolutely not use my phone while charging it because that will to a 100% result in my screen going wild

I am also facing this issue. I mildly heat the screen using heater the problem solve for one or two weeks then It again appear. I found another thing that this issue may solve if press the right side of speaker hardly. Please try these and report

Same here. It happens when my screen is a bit oily so if I clean it it doesn't do it anymore.

Happens to me too, exactly as OP said, Bayer MB525
Happend with CM7.2 and CM10, I don't remember having this in stock Froyo 2.2.1
EDIT: Things that make it happens more often:
1. Any kind of liquid over screen (mainly water)
2. While connected to an USB

WOW ... such a mass of users with the same issue ... and no one ever told that before?!
OK, so we are facing an big issue with all roms and all kinds of devices / displays ... so maybe it is a driver problem, beacause it is solved if you turn screen of and wake up again ...
the issue with the charger is named here too ... i also had this problem ... with low battery and charger the screen reacts like an resistive touchscreen, not like an capacitive ... maybe these are all the same issue ...
No dev here, that can pick this thing up and have a look at it?

Then let me add that right when it happend, i saw a tiny sweat droplet on the screen. I wiped it away instantly, but the effect stayed for another couple of seconds. Might really be that the touchscreen/driver-combo gets temporarily overloaded from the continuously moist spot.
I had that effect on other phones too, always capacitive screens. If that's all there is to it, there's probably not much we can do about it to solve it other than to make the driver less sensitive, but that would be a bad thing, if you ask me. I like that it reacts at the lightest touch.

Yeah, it reacts fine. But the idea of overload is nice ... Maybe it could be solved by setting up the Multi-Touch-Points to 5 e.g. ???

I think we need an update zip from our great developers to reduce the sensitivity of our touch screen especially for those who realy suffering due to this defect. We can find lot of topics regarding this issue in various headings like !My phone become crazy, touch screen malfunction etc! In QA section

Yeah, for sure .. but if there is no dev reading this posts, there won't be any zips ...
and with the xda-board-rules you can't open a thread for that in the Dev-Section -.-
So ... we will be alone thanks to the admins and the board rules, cause no dev will read the Q&A Section ...

My phone Defy+:
I had this issue on cm7.2 tried following solution but none of them works.
1) Changed to cm10 thought it might be Rom issue but no i have ghost touch on cm10 too.
2) I applied screen guard to see if it wrks but not it does not wrk i still have ghost touch.
P.S. While charging the phone GT disappears.

Try to heat ur touch screen lightly using a hair drier
