Touchscreen not responsive unless left softkey is constantly pressed

Hey guys!
I've seen people complain about broken Wizard LCD/touchscreen around here but none of them said anything about partially functioning touchscreen. So here it goes:
A few days ago my phone stopped responding to taps. Just like that! I updated the phone with the latest ROM from HTC (official) and no change. Since then I've been lurking this forum trying to find something similar ...
I've flashed it with custom roms, now I'm trying the WM6 with the hope that maybe the touchscreen will respond to taps by itself, without me having to keep the left softkey pressed while tapping. I can't decide if this is a hardware or a software issue.
If anyone should have any idea about this, please advise. I'm not afraid to open it up or anything like that...
ps: waiting on a replacement touchscreen I ordered off of eBay. ($12)
Thanks a bunch,
kevin

Same Problem
My touchscreen has been acting up lately and today it just stopped working. Tried many things like you with no luck. However I followed your advice on pressing the left soft key and the touch screen started working.
Does anyone have any clues?

touch screen prob.
if your touch screen is not responding then you have to chang the touch screen if it responce some where in time then you open you device and just resolder the touch screen film connector (back side of screen)its just get drysoldered thats why these things happen like you press rite side of screen and it geting work again if relese its stop working................
you have to do only re sloder the connector of touchscreen

Different Problem
Like the post originator said, the screen does work, you just have to hold the left soft key down while tapping. Also did take it apart and didn't see any problems.

Mine just developed this issue, anyone have a fix? I've got a digitizer (Touch panel) on order from ebay as a 1st step. Anyone have any other ideas?
Thanks!

Ok this is odd, but I'm suddenly having the same issue. Touchscreen doesn't work unless I'm holding the left soft key as well... This has to be software right? Anyone have any ideas yet?

I dont have this problem.. but this is 'interesting' I'm wondering, if it is hardware or software problem. For hardware problem, you can try pressing on the area around the left softkey rather than the left softkey. For hardware, you can check to see if it is working after a hardreset?

This issue has to be related to corrupted software that was installed, I mean how can this many people have the same exact problem around the same time if it's hardware related. Compare notes: All those having this issue,submit the most recent software that was installed, and if everyone installed the same thing, then that's the culprit!

Touchscreen issues

I'm having some weird issues with my touch screen. I'm using the Touch Keyboard input method so I can use my thumbs for typing instead of using the stylus all the time.
Very frequently, when i use my thumbs to push buttons near the bottom middle or bottom left of the screen, the start menu auto pops up! It is absolutely driving me mad! I tried to recalibrate the screen, doesn't help. I tried to take off the screen protector and try again, no difference.
Has anyone else has this happen?

Hi,
Yes, it's a common Problem with the Trintiy.
But be happy, that you don't have these Problems.
I have heard, that there are Problems, when the device heats up and the casing pushes on the top-left corner. But with my Trin it only occurs, when I'm tiping something and push a little bit to hard in the middle of the screen. But it doesn't disturb me too badly, as long as it won't get worse.
Greetz

So it's more of a design issue than anything else? Damnit! I was hoping there'd be some sort of fix or that it was just my phone that was defective somehow.
Sigh, I've never noticed this problem until I started using the soft part of my fingers to type.
Anyways, thanks for your reply.

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

[Q] Touch Screen Problems

Is anyone else having problems with their touch screen?
It will occasionally become unresponsive, and other times will just start 'clicking' repeatedly in random spots.
I find myself having to turn the power off and on (via the button, not a hard power cycle) to fix the issue. Its starting to get annoying.
Anyone else?

Yes, I am getting the same thing but I've found that if I just turn the screen off and then back on it fixes the problem. I don't need to reboot.

You think this would warrant an exchange? or is it just how its going to be?

I've put several hours on mine, but haven't experienced this issue. I don't know, if this happened to me more than once, I probably would exchange it.

It was happening to me all the time. I had to get a screen protector and haven't happened since.

Very good "solution" to what should be an obvious problem. The Nook Color has a *capacitive* touch-screen. If you get "junk/gunk" on the screen, it's gonna cause you issues. I find this to be the case while holding my NC and playing Flight Director for a while. The issue: My hands become sweaty and as a result of the slight film of sweat/oil on the screen, the NC's ability to measure the capacitive changes on the screen (and react appropriately to them) is compromised.
Keep your screen clean and you won't have this issue.
Note: after you wipe the screen down (damp cloth, etc), you will need to click the power button and go the lock screen and then back into the NC before it works right directly after cleaning the screen. The dampness of the cleaning cloth throws up the calibration enough to cause very strange things. My experience with "correcting" this issue tells me that in some way, the NC is recalibrating itself when you go to the lock screen.

johnopsec, this has been my experience as well. After cleaning the screen from finger-jam i don't get the phantom clicks. I also noticed that because I live in a very humid climate (Florida panhandle) there will be a thin moisture layer buildup sometimes and it really helps to wipe this off. I also have an incredible that does not have this problem but it has a screen protector which, I am guessing (and as gigadigit expressed), fixes the problem. Just make sure the screen is clean and dry before applying!

screen response
Also,
If you are holding the side of the case by the screen this throws off the touchscreen, I was having the issue where it would be clicking and multiple letter inputs when typing.
Also when it is laying flat and you have the power cord plugged in you may get multi letter inputs.
The trick, hold it by the back not the sides.
and if you have it plugged in and need to type don't leave it laying flat.

I have experienced this problem and loosely seen it correlated with moist fingers.

no moist fingers here and on my 2nd nc. this ones starting to have the ghost touches too.

My Nook Color started acting up after paying levels 3-4 to 3-6 of Angry Birds. I'm not sure if Angry Birds caused the issue or not as I haven't gotten it to do it in another app. I'm running 1.4.2. Doing a lock and unlock fixes the problem until it returns.
I managed to get Phone Tester to run after it got into this state. I made a video of it using a crappy webcam. There's a stuck finger in the corner.

Touch Screen issues while unit is plugged in..
It seems I have read on some forums that some people have screen issues.
Personally I didn't experience this until I tried to use my NC while plugged into it's wall charger.. It seems to act as if it has a grounding issue, which is not the case when the unit is unplugged.
So when you are running your multitouch or touch tests, do it without the unit plugged in..

I have had the same problem with my touch screen. I have the nexus live wallpaper and whenever you touch the screen it sends off the animation. Well sometimes it just goes non stop and sometimes opens up the window where you can apply a widget. I guess the most practical solution would be a screen protector but if not ill restore it and send it off to B&N

There's a small little app in the market named "Nook Screen Recalibrate" this app is super simple and easy to use. I hope this helps
https://market.android.com/details?id=com.assid.android.nookrecalibrate&feature=search_result

Here is the issue I have...
Right is the N button side. Just a reference point for this.
Reboot the Nook (I use CM7).
Bring up the keyboard
Touch Q in the center - you get W.
Touch Q on the right - you get W
Touch Q on the left - might get Q but you usually get W.
Recalibrate using the Nook Screen Calibration (above).
Q now gives Q unless you press on the right side of the key. I also notice I still have to hit the back arrow more to the left or I bring up the keyboard.
I've learned to live with it, but the left side of the touchscreen is slightly off and you have to touch to the left side of any object on the last 1".

yeah, for me it's the edge of the screen along the right side. it's less sensitive then the rest of the screen. I found that calibrating 2-3 times really works best.
There's also a fix in the nookwiki, but i can't get my adb to work on my laptop, I think its the drivers.
http://nookdevs.com/Recalibrate_the_NookColor_touch_screen

What is the left and right side?
I should have said that left is the side opposite the N button.
I downloaded Multi-Touch Screen from the market and I can see part of the problem is the angle of my finger. Straight on it's better.

Nook Color Touch Screen Problem
Having similar problem as described, after two years. Extended warranty expired ... two weeks ago (of course).
Tried cleaning screen, no help. Have not tried screen saver yet, but will.
In the meantime, I notice the comments about touching the sides, and I noted that as well.
Is it possible that this could be helped by opening it up and re-seating the case? Has anybody tried this?

Touch Screen Unrsponsive after pocket time

My touch screen is unresponsive after I pull my streak out of my pocket.
After a minute or so it start working again.
When I first received it I did not have this issue.
I have flashed DJ_Steve's rom.
Has anyone else had this issue?
Should I send it back to Dell?

just saw your post after posted my one.
http://forum.xda-developers.com/showthread.php?t=876931
did u try in landscape mode?

So when I pull my streak out of my pocket it is on the lock screen, which for me is always landscape.
And with the screen unresponsive I can't unlock it.
To add a little more detail, sometimes the screen is only partly unresponsive. e.g. I can sometimes partly move the sound drag button, or the unlock button, but not fully.

I have had this issue after flashing 1.4.6, my streak is in landscape. I used dell 1.6 before that with no issue.
I have been using no lock off the market, when at home to by pass the problem, however the screen can still be unresponsive but only parts of it, for example one row of apps on the home screen can be pressed but others cannot.

Have you guys tried to do a screen calibration that worked for my streak 2.2 Dell bug fix version

It's not just you guys, I have this problem as well. I miss atleast 5 calls a day because I can't get it to slide to answer the phone call. As far as the home screen from pulling out of the pocket, I have found the pattern unlock to work the best with no problems. If I get a phone call, I try pressing the go back button on the capacitive screen and turn it to landscape and it seems to work. A pain...but I guess running a custom ROM has to come with a little sacrifice. I'll live though.

Doing the screen recalabrate worked.
That so does not make scene but it appears to have fixed my problem.
Thanks

No prob man

I have found that doing a long press on the power button to bring up the power of menu, then going back to home screen makes it all responsive again. Not a fix but lets me unlock with out having to wait for a minute or so.

I've had a similar problem before too when I first got the streak! Try keeping it in your pocket facing out and away from your leg instead of toward...
Also - maybe the type of material a person wears might affect it. I noticed this problem occurred more in my jeans facing my leg than in my suit pants facing out.

Mine's been doing this since I went to 2.2
Evidently the update made the screen more temperature sensitive or less, depends on how you look at it. I noticed that if I had the phone in my pocket facing my body, it was unresponsive until the screen cooled. Then it responded again. If I put my phone in pocket facing away from body, no issues. I also noticed it was unresponsive after I was on the phone talking ( the heat from my cheek?).
Have not found a resolution to this other than to keep the screen "cool" at all times so it would respond to the warmth of my fingers.
Just another bug in the 2.2 update it seems, so until Dell does something about it, Punk'd by Dell.

+1. I started putting it in my pocket screen out a few days ago (whether jeans pocket or inside jacket pocket), and it hasn't happened once since. When I do forget and put it in my pocket facing in, it's a 50/50 chance it will happen.
It seems as though constant contact with skin (through a thin layer of cloth) desensitizes the capacitive screen somehow, even (or only?) when the screen is off. Strange that the issue never occurred on Donut. (I'm on DJ Steve's Froyo 1.5.1 now.)
I hadn't thought about temperature as a possibility, and I doubt that's all there is to it. Anyone live in an extremely warm climate who has had trouble with screen sensitivity in other circumstances?

This can be greatly reduced by the way you carry it in your pocket... I'd much rather have it facing inward - but then the sticky unlock acts up. Facing outward it rarely happens.
I don't think anyone noticed this on donut because you only had to press the menu key to unlock... not use the screen. Question is, was this happening on 2.1?

I will try that for a few days, I had noticed that it did not happen if left the phone on the side or on my desk all day.

I always used a pattern unlock on Donut, not the Menu key, and this never once happened in over a month of daily use. Day one after installing Froyo I had to stop using the pattern unlock because it was driving me nuts trying to unlock the thing after taking it out of my pocket. Of course, any unlock I tried was impossible with this issue, and the only thing that really worked was just waiting for it to start working again.
No idea about 2.1, I only had it installed for about an hour.

i solved putting the streak in pockets with the screen towards the ouside of the pocket, and not facing the leg

+1million to all of this.
This was driving me nuts, thought I was the only one, exchanged the streak once already because of it.
Just had my coworker the cubicle across from mine try putting his streak in his pocket for 15 minutes, pulled it out, SHAZAM, touch screen didnt work for a few minutes.
Verified here on 3 streaks. 1 on 1.6 and 2 on 2.2 all have the same issue. 1.6 unlocks, but then nothing works until you mess with the facebook app, or another scrolling app, then everything works again.

did anyone happen to report this to dell? I think we might start to have a case here.

Another one with this problem. Noticed it yesterday. Screen facing in. Will try to face outwards next time in a warm building with carrying in pocket.
Same thing here though. Cant move the unlock but can slide the sound just a little bit. Funny ****
