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

During the cold times i got huge problems with my screen... I'm not able to press "L"
and also the border of the screen got huge problems to respond on my touch, and sometimes the screen starts to jump from left to right.. but when i lock the screen and the 'task killer' kills some apps (FB, google search) then it oks.. any suggestions, tips ? I'm using FroydVillain 1.7.2
Have you tried wiping (full wipe) and installing a new ROM? that might help, although its unlikely to really. I sounds to me like a failing touch panel, but I'm no expert
I started having the same problems after flashing cronos 009, but then my little boy had pressed the screen a bit as well so don't know what did it
same problem like you but i had problems with letters 'M' and the backspace arrow
I flashed the original Htc rom and it kinda improved a bit
I rerooted and tries other roms and still had to problem
Now what I did was hard reset my hero and running the official Htc rom and its a lot better now atleast the screen aint jumping anymore.
I still have root but decided no more custom roms for me now
how cold its winter for you?
please what is bottom level degrees for hero working and magic also?
ty!
Is it just the bottom of the screen, that isn't reacting correctly? It might also be a hardware issue of the touchscreen... I had this some time ago, seems to be a common problem/bug among heroes... but that shouldn't have to do anything with temperature. Just to let you know, in case it gets worse...
I had the same thing as you, only I had it all the time, when the screen gets warm (charging) then it worked fine (not moving by its self) , but I the bottom of the touch screen was totally dead, I had to rotate 180 to type and use the trackball to reach the menus :-D . A while after the track ball was almost totally busted, I purchased a new digitizer on eBay, it works perfectly, (this post is the evidence..) I had to open and move the connector about 10 times before it worked well, but this definitively fixed it
Hope this helps

I had this exact same behaviour but I hadn’t attributed it to the cold weather. The stock ROM seemed fine but any custom ROM had the issue. Anyway I sent it back to HTC under warranty and they replaced it with one that works fine.
I heared this same stuff about the iPod. When putting it at a window when its very cold it brakes the 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.
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...
Hello all, I hope this post can help you with the same or similar problem I had.
My LG gt540 started having a problem 2 months ago, the touchscreen got offset by 2 centimetres(1 inch) verticaly down, this was very annoying specially texting and couldnt access the top panel. Ex: to unlock the phone I had to press 1 inch above the green button.
Sometimes(I dont know why) it went back to normal, but about a week since the problem started it just got permanent, I tried rebooting, taking the battery, etc, nothing worked... Even tried to go to the calibration option but the offset was to much so it said out of range...
Then I read something online about the heat caused touchscreen problems, so I was thinking... hardware dont really like heat, and I always carry my phone on my pocket, the body heat could be damaging the touchscreen, lets try cold, it could solve it, long shot but what do I have to lose?
Left my phone in the freezer for 10 minutes, turned on, and it worked! for 1 month now its back to normal!
Hope it helps you, but try first freezing it powerd off, may be safer.
i have got my phone 2,5 years and i havent got any insue with the touch screen
Hi
My phone started doing the exact same thing a week ago...
This is the only thing I haven't tried, lets see if it works for me....
Thanks
I've had screen calibration problems since i started flashing custom roms.
In my case the screen positions are slightly off at the right side of the screen. When I want to type an "p" i have to touch where the "o" is on a german keyboard.
I'm trying your solution right now.

I have problems for the outer 4 sides.
It's worth to try.
Didn't work for me, it was only fine for 5 minutes....
Also didn't work for me.
Besides, after puting it in the freezer the display protection foil now looks a bit strange.

Hi, sorry for waking this thread up.
I also have the same problem, press 'o' to get 'p'.
I want to ask you guys who already tried this method. Did it work?
It's tempting, but it might be better to know more info.
Thanks.
Hello folks,
I've googled a lot but maybe I used the wrong terms or it's a rare problem. But my phone has a small annoying bug. The bug I'm facing was always there but after the latest update it occurs much more.
Most of the time it happens when you unlock the phone and start typing. In the video below you can see the problem.
Sometimes the recent apps and back button refuse to work while this happens. Not always.
Is there anyone else that suffers from this strange behabior?
I allready tried to remove the TPU case but that didn't solved the problem.

the solution is simple,just make sure ur fingers aren't wet!
Over a period of time (if you looked at your phone at an angle with the light reflecting off) the Gorilla Glass the phone needs to be wiped down, preferably with a micro-cloth (the same type you use on glasses). The oils on your hand, combined with sweat/water, can do freaky things with the touchscreen.
I have been using a stylus most of the time to type and interact with my S7E phone. Not only that I like it better I find it with my big fingers I am more accurate when I am typing and interacting with the phone.
But do not forget this S7E is completely covered with Gorilla Glass and needs to be cleaned like all other types of glass does...good luck.
Cheers!

The exact same thing is happening in my case (atleast has become more pronounced since the latest update), the recent apps & back button become unresponsive after you unlock the phone and there are random ghost touches. The problem seems to normalise after you lock & unlock the phone using the power button. Any insight on the same would be helpful.
I cleaned the phone multiple times. Actually I clean it every day.
As arun.subrm says. It goes away when you lock and unlock the phone.
Very strange. Actually it gets worse after every update. Today it happened over 3 times in 4 hours. Rediculous and very annoying. It makes it an unreliable product this way. You don't know when it will happen.
Still waiting for that moment when I accidentally buy a living room couch on ebay or something xD.
