Touch screen big issue : nearly not usable - G2 and Desire Z General

Hi all !
Since a few weeks/months, I have my touchscreen which becomes less and less responsive. In fact, the issue is that sometimes (say one push every 5) the release is not detected, meaning that my finger is still detected while it is not on the screen.
This does not seem to be software related as I have same issue with different ROM (Cyanogen, MIUI...). Also, I changed the touchscreen (bought on eBay) and I still have the same issue...
I tried with different positions, for example touching the edges with my other hand, or opposite letting the phone on the table without any other touch than my finger, but issue is still viewed on the same rate.
Any idea ? Anything to try to fix ?
Thanks !

You haven't recently installed/changed a screen protector, have you ? Some of them make the screen a lot less responsive.

I had this problem during winter but everything is OK now.I am pretty sure that it is the cold weather that confused my device.Maybe you can have a test on different temperture.

Thanks both of you for your answers !
No, nothing changed : screen nor case. And temperature does not seem to resolve anything... I also have bought a new digitizer, replaced it, I still have the same problem...
Maybe a grounding issue ? The digitizer connector ?
I'm afraid I'll have to buy another one... maybe a broken one, with different issue...

Niki touch screen not working when slider is open

Anyone here experiencing the same problem? At first I thought that was normal, but at some point the touch screen worked while the slider was open and I was really happy with it but now, it no longer works what gives?
am i the only one experiencing this? do you think a ROM upgrade can fix this?
Sometimes (very rarely) the screen doesnt come on and I have to reset, but nothing like you descrived, sorry...
aw! i guess i have an isolated case. thanks twolf!
it's a screen cable problem. just fix it
last week, i had the same proplem. So i sent it to the guarantee service. They replaced the cable, which is connecting the screen with mainboard.
too bad my phone doesn't come with warranty. thanks for the info guys
my phone has the same problem,and I had used many roms, and all of them have the same problem.
my screen isen't working when the keybord is closed,
aneybody have the same problem??
problem
yes i do have the same problem ... my htc niki100 was not working when slide closed ... but when i open it works fine .... sometimes when slide open also it is not working i mean the touch screen ... i removed all parts of my htc niki and i take a look at that but all was fine and i dont know what was the probelm... i think htc failure model is niki... really pissd off guys due to this niki ... if any came to know how to make work that ... just post it and for u i am thankuful..
it is hardware problem. sent my device to service center and they changed the board for free since it is still under warranty. they said it was wear and tear. so it is only matter of time before the new board suffers from wearing out again. unless stop using the sliding keyboard, but tat's the main selling point touch dual is built for =\
how much is the cable $$ connecting the lcd to the boarD?
my niki is out of warranty............can any mobile phone repair shop fix it ?

If you google around you'll see this is quite a common complaint with the Touch Dual. There seems to be a certain flaw with the screen and cable which was never addressed. I had the exact same problem & eventually sent the phone back to HTC to be fixed.
Be warned though - HTC would not fix my phone eventhough it was still under warranty. They said the problem was due to User Mis-Use. My ass it was. I argued it out with them but in the end I just paid the UK£60 to get it fixed - robbing bastards!
You all seem to think it's a hardware issue, and I'm experiencing the same issue, but only under Windows Mobile (I've tried both 6.1 and 6.5 - all sorts of various roms). Android on the other hand, works fine. :/
EDIT:
Well now it's working on Windows too. After I ran Android... SO GIVE THAT A SHOT I GUESS. o.o
Hi
I've got the same problem it's starting to piss me off.. :[email protected]
1) screen doesn't work when slider is opened
2) screen doesn't work at all at times but works again after ....??? xx hours or so.
My warranty has ended, any tips?
Upgraded Windows Mobile to official WM6.1 from HTC.com website.

i came in here to say the same thing.. weird. works fine in android.............
another thing worth noting is that if you keep a finger on the screen while sliding it seems to work everytime
My Niki has the same problem, when slide is open i cannot use the "send" button on the touch screen - so i have to close the slide, to send a SMS.
I bought a HTC Snap now, so my NIKI just lies in the drawer...
Sad, i like the Screen resolution and Rom software on the Niki better than the HTC Snap.
At http://www.ppctechs.com/HTC-Nike_1047/repairs.htm you can buy a HTC Nike ToolKit with special screwdrivers, maybe the cable just needs to be aligned properly, or fixed in a socket...
Has anyone tried to fix it themselves?
guys,
I had the same problem. In fact, my touch screen was totally not working at all. Some threat recon it's loosen cable so i opened my touch dual and tighten the lcd flex cable. It worked after that, but not working when slide is open. I've just changed the flex cable myself and it's working fine now. hope this help.

[Q] touchscreen issues?

Before, my vogue had issues with it's touchscreen (dropped it too many times).
Now, it seemed to work for like 4 days without major problems. Usually if it freezes up, a simple reboot will fix that. Nowadays, it happens more often.
The main problem is that it'll freeze up and I'm unable to do anything with it (touchscreen becomes unresponsive).
Anybody experienced this problem? Is it time to get a new phone?
Would a new digitizer affect it?
I read a forum with a person saying a new digitizer was the cause of their touchscreen not working. It may fix yours though but also try calibrating your screen.

[Q] Wandering screen alignment??

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.

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

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
