Diamond touch screen not reacting when touched.

The touch screen of my htc touch diamond is not working properly. It does not react to my touch. For me to get it to work I have to rub my fingers over it then it will be work again as normal. This only lasts for a few minutes after a while it becomes non responsive again. It is like it has to be warmed up to get it to work. This a problem when it comes to sending text messages. (the problem remains when I remove the protective screen).
Anyone has a answer to this?

remember the last program you installed and remove it , maybe it cause this problem
or try hardreset

Tried both methods still not working. I have ran out of ideas. Anyone else expierenced this problem?

Im having the same problem with my Raphael

To really know whether it is a hardware problem or software based problem, I recommend a hard reset and see whether the problem persists...

this is likely to be water damage on the screen. send it off for warranty see if they fix it. they fixed it for mine.

The thing is iv noticed the touch screen isn't thermal reactive like most touch screens. In other words the temprature of your finger is sensed on thermal screens, the HTC you can use anything solid that makes contact. Usefull if you have long nails.
So I'm guessing its probably hardware if it works after a while of 'rubbing' it, But like otacon said I would do a hard reset before jumping to that conclusion.

Same problem
Hi there....i saw that this is an old thread but did you manage to get it to work?
Cause i have a HTC Diamond that i changed both the displays on(LCD and the "point screen") and everything works fine on mine now,even tried to recieve phonecalls and it works excellent so as i said EVERYTHING works like a charm but the touch function.....it doesn´t react in any way while trying to use the touch function and i have tried soft reset,hard reset,new rom,checked all the internal connections around 4-5times and everything is ok but the damn touch function won´t work whatever i do with it.
I haven´t "glued" the 2 screens together,but they are sitting close to eachother so it should work anyways right?
Now from what i have seen on internet is that there are different versions of touch screens available on the market and i ordered the LCD from one company and the touch screen from another.
Could it be so that they aren´t compatible together or am i doing something wrong?
I´m still stuck at "Tap the screen to set up your Windows Mobile-based device" and can´t get any further after trying another rom.
Please help me out if it´s possible.

I have exactly the same issue you're experiencing, I've actual flashed the original rom, thinking that might put every settings in place to make it work, but no joy.
I don't be leave the concept of the weather condition equate to the performance of the device, as read in some of the forums. reason being I've had mine in very hot climate Country for over year whiles working on a project in Africa. In fact that was when I realised the the screen has become unresponsive.
I think this is a hardware issue.

It´s working perfect again
So since my last reply i ordered a new touch digitizer and lcd display and soldered them together carefully(first time i bought a lcd and digitizer from two different companies so they weren´t compatible with eachother and made the touch defective and second time i bought both digitizer and LCD screen from the same company and then it worked) and it has been working perfect since i last wrote my comment so i recomend you check the contacts/connections first on the phone because i had some minor issues with them when i assambled the phone again so i had to #wiggle# the contacts so i made sure they were connected.
We had a company here that sold lcd displays and digitizers out for a total of 30dollars with shipping so i had nothing to loose on it so that´s why i ordered a new set again and that made everything work as a charm since i replaced it.
Now i have searched online about the displays and the digitizers and i have found out that there are atlast three different versions of them so if you order a digitizer and a LCD make sure you atleast order both from the same company so it doesn´t happen the same to you what happened to me the first time.
Cheers and hope i helped you somewhat or else just ask on and i should try to answer.

Nexus One Screen Accuracy Issues

Hi
I purchased my AT&T 3G compatible Nexus One the first day it went on sale, I just updated to Froyo and I notice that sometimes my screen fails to respond. I have to power on and off my screen for the issue to go away. Some examples are when im typing and I hit and key and it chooses another one or i'm trying to scroll on the menu and even if im picking something from the top the phone highlights the menu icon at the bottom. Are this issue just with my phone? has anybody been able to fix this?, If i call HTC support and they send me and new phone will it have the same issues?
Please guys let me know... this is driving me crazy

the screen on this phone blows... plain and simple... you will just have to get used to it...

do you think i should get rid of it?

Hi,
Don't get rid of the phone. You don't have to reboot, just lock the screen by pressing the power button, then unlock it. I've had it a couple of times but it goes away when I do that.

Also, be aware that it's very sensitive to any part of your hand that might be leaning over the edge of the screen, or hovering over the touch buttons. For example if my finger is hovering over the home button but not touching it, and then I touch somewhere higher up on the screen, it may respond as if I had pressed menu.

So...are you saying we are holding the phone the wrong way? Lol.

the nexus has this issue with the screen. its not a big deal, just lock the screen and unlock it, it fixes the problem. its some kind of mis calibration issue. yeah it sucks, but not the end of the world. only takes 2 seconds to fix it.

Heehee. I guess Android isn't immune to that either. Nor is the EVO or Droid Incredible (not identical problems but they're still there). I think it's inevitable that as we try and jam more and more "magic" into a single unit, things start to crosstalk in unpredictable ways and glitches emerge.
I have to say, the touch-sensitive buttons on Milestone & N1 really throw off people who haven't used them before. If I pull up a picture or video and I'm showing it to someone, inevitably they clutch the phone with a finger on a touch button, and then I have to get them back into the app and explain what not to touch. That's one reason I'd rather have physical buttons such as on the Desire.

I have this touchscreen problem as well, and yes its a big deal for me! I spent $580.00 for this phone. This shouldnt be happening at all! I've tried all sorts of troubleshooting(deleting cache partition, updating to the latest froyo, restoring factory settings, tried without installing 3rd party softwares, etc..) before i finally came to the realization that this is a hardware issue. Ive tried narrowing down to possibly when and how it occurs, but you can't. It just happens when it happens. It's impossible to predict. When this problem occurs, watch closely to where the calibration is off. During the problem, the calibration is only off on the bottom half of the screen, more so close to the bottom right. The top part will work perfectly. You can test this out by swiping left to right or vice versa on the homescreen. This problem will also affect the Pinch-to-Zoom in Browser, and the ability to type correctly using the default keyboard or 3rd party's like Swype. I received an exchange thru HTC a couple days ago, and not only was this exact touchscreen issue prevalent in this unit, but also it suffered from the purplish screen tint. This issue seems to have existed since they first launched this phone, but for some reason there has been no fix for it. It's funny that the EVO received a software fix promptly after the issue was reported by many. Why not the N1?? Because it's hardware, that's why! Feature wise, this phone is by far my best PDA, I mean I really love this phone, but $580.00 is too much for such an issue to exist. I'm hoping that there's only a number of bad batches floating around. I would say, if i receive 4 exchanges, all with the same exact issue, i may look into a class action. I definitely wouldn't want to be stuck with this problem after my year warranty is up!

I haven't had the 'crazy screen' thing since FRF85B, I assumed they'd fixed it.

I haven't had it since upgraded to Froyo too

not hardware problem
I encounter this problem a couple of times and I tested two things: useing trackball I ran touch sens app and tested the touch sensor, it was fine, second I killed all apps using a task man and it fixed the issue. I am on froyo.
Sent by my Nexus one.

I experienced this yesterday for the first time on FRF91 (unrooted Stock build). I couldn't press the "enter" button on stock keyboard. It just kept choosing Delete instead. Lock/unlock screen via power button sorted it.
So the problem is still there in latest build of FroYo (for me anyhow!)
Anyone else?

I've had this problem ever since I got my N1. Sometimes made me want to switch back to my iPhone! Makes it a lot harder for my son (2 1/2) to use the phone too.
Seems reports are mixed to whether froyo fixes it or not. But it gives me hope. I've been using CM5.0.8, holding out for their final release but this gives me a reason to try MCR.

I have upgraded to FroYo FRF91 but still see the same issue.
Sometimes I face with the calibration's flaw for the left bottom corner of the touch screen.
What a shame I have paid 750$ here for this phone. I really love it but this flaw screwed up all the pleasure.

So it is a hardware issue? Maybe we can get htc to replace our phones.

Well looks like I still have this issue with frf91.

i think no one really knows. Would be a strange hardware issue which can be fixed by locking and unlocking.

[Q] Unresponsive Touchscreen?

Hello my fellow android hackers, I need your help. Recently, my touchscreen has been completely unresponsive at the top of the screen, near the notifications bar area, but three times as thick. The problem with this (Besides having to go to my homescreen every time I need to access my notifications, or having to go into landscape mode) is that It often renders my phone useless. Often times when I select an object or slide across homescreens, the UI will select an object at the top of the screen. Shortly after, I will be unable to select anything on the screen, and if I try, the UI will select something at the top of the screen and will begin erratic movements around the homescreens, web browser, and almost any touchscreen interaction. This movement will occur whenever I try to interact with the phone's touchscreen whenever it is in this state.
This is not native to any rom, I've tried reflashing and trying many different roms. I know the touchscreen malfunction is native to the hardware, since I've tried reflashing the 2.xx.x.x.xx.6 and the 2.xx.x.x.xx.5 ruu. I think I will need to replace the touchscreen, so could anyone direct me to where to buy the part, a website to install the part, or both. I'm pretty sure I can find how to install the part, just not where to get it. Also, I'm not sure if it's a problem with the inner or outer lcd screen.
ANYWAYS, this problem is more common with the HTC Hero GSM, but HTC has said that some hero's have bad touchscreens.
Heres a link to a video demonstrating the problem. (I am running CM 6.0.0 test 2, it's a great rom)
http://www.youtube.com/watch?v=1ORe2rjWt7A&feature=related
This is with the hero cdma, but the broken area is on the side of the screen, not top.
http://www.youtube.com/watch?v=JYQnCOAtTLs&feature=related
This is to the GSM hero, but the issue is with the bottom of the screen.
This is a problem native to the HARDWARE, and occurred during normal use of the phone, just shortly after watching youtube videos and browsing the web.
Could anyone even direct me to a location to get this repaired, since the Sprint store said there was no way to fix it, but online many people had this issue and got it repaired by HTC customer care. Could anyone confirm this, or state the time length of a cdma sprint hero warranty purchased from Sprint in the US?
(Occassionally the phone works, but only for a short while and then It starts acting up again, usally during data use, like web browsing or using several apps)
Any help would be appreciated.

Is it humid where you live? Do you use a screen protector?
Sent from my HERO200 using XDA App

Yes, it is humid, and I don't use a screen protector. I think the processor was overheating during heavy use (watching video, etc) and I left the screen on for a while. I think that this damaged the screen.

Have you tried a different rom, or maybe flashing one of the new any kernels for your current rom? Almost sounds like it could be a driver issue. I did have a friend that had this problem on his stock hero, and sprint replaced it for him. If you ruu and it still does it, make a scene, they will replace it.

had the same problem with my hero, unresponsive directly below notification bar, as well as becoming completely useless randomly. took it into sprint, and the tech seemed to know exactly what the problem was. an hour later, it was fixed as well as my peeling buttons replaced...free. apparently the touch sensor was going out and it must happen more often than not considering the tech new what the issue was immediately.

Ok, I will not start another rant and rave I promise, BUT, I will say be very careful going to Sprint with a problem. I just had the same exact problem, I had to go to FOUR different stores, and finally instead of fixing my SPOTLESS Hero, they ordered me a "new" one, it has scratches all over the screen, the back cover hangs off, my hardware buttons(home,menu,ect...)are lose, and the metal where the ear speaker is is sticking out, be very careful dealing with sprint.Oh, yes this all happened in the last 4 days, they didnt give me a loner phone, and it took me 3 days to get this piece of **** they call a new phone. Just my experience.

[Q] Touch screen dead spots

This may be a problem beyond the scope of android, but seeing as I'm running it, I thought I'd try here first.
I've noticed that the lower left hand side of my screen has a "dead spot" where touch is simply not registered. To illustrate, I went to screen calibration's test screen and drew a straight line along the edge of the screen. (See Attachment)
I've tried recalibrating the screen (manually and resetting to default calibration) as well as wiping data and reinstalling the system. Reinstalling the system worked once, but then the problem came back and subsequent reinstalls did not fix the issue.
I'm running Incubus26jc super froyo [RLS 12] on the 15-07-10 340X480 Froyo Kernel.
Anyone else seen anything like this? As far as I can tell, the problem is not getting any worse. Currently, it's only a hindrance when trying to use keys in that region, but I can work around it by switching to and from landscape. It's a bit of a hassle, so I'm hoping someone may be able to shed some light on the situation.
I was sure it was hardware until the system reinstall fixed it, but am now baffled as I can no longer replicate the fix.
I have not tried reinstalling the kernel but will at some point in the next day or so. I'd like to avoid switching back to WM to check if the problem persists, but may have to... we'll see. Doing everything I can to make this phone last until the Incredible month of February when I'm up for an upgrade.

dont know the issue resolution... but i have the same with my touch vogue.. and in the same 'area' apparently as well.
hard for me to hit the 'a' key on my keyboard. hehe

I'm glad to see I'm not the only one... anyone else?

Bottom right corner for me... I was able to calibrate around it but it took a few tries.

The sensitivity across my screen was inconsistent some time ago. I found that years of my abuse had taken a tole on the exterior of my phone. It eventually got worse and I bought a new housing (with a new digitizer) on ebay for a reasonable price. If it is hardware then it really isn't that hard to fix if you like taking things apart.
If you're sure that win mo accepts input from that part of the screen then nevermind my post. I would play with a painting app though and investigate the hardware further.
I may be talking a little out my a$$ with this part but.. is it possible that in calibrating your screen the os may change it's settings on how hard you have to press and such also. that may be how you got it working.
In any case, my investment in a hew housing was well worth it considering how modern my old phone has become thanks to the developers here.

In my case, no - when drawing a straight line down or across the screen, the line starts 'moving' away from the stylus (like the picture in the OP).

Gah... now it's shutting itself off randomly and the dead spot has grown. Not good at all.

Yeah, mine was better for a while then 'slid' again. I ended up swapping the digitizer with my other Vogue and things are back to normal.
Sent from my Full Android on Vogue using XDA App

I have another vogue, but am weary of doing anything like that. How hard was it to get done?

All you need to do is switch the front half of the housing rather than the digitizer itself- it's not hard. There's a teardown guide somewhere in the forum, Google Vogue teardown and it should be at the top.
Sent from my Full Android on Vogue using XDA App

The only thing that worries me is that my spare vogue exists because it was dropped in a muddy puddle. I'm hoping the water damage isn't too bad. Guess we'll just have to see.

it is really annoying
I have the exact same problem and I too thought it was a hardware issue till I saw this Thread. I was ignoring it till two days ago when it started really bugging me. Now, I don't even need to press any button and it automatically gets pressed around the curve and I have a google search box there, so it keeps on searching for eee or sss randomly and started draining my battery. Is there a proper fix for this?

I thought I'd chime in too... I could never seem to calibrate the touchscreen properly in either Android or Debian. Changing the screen resolution (i.e. msmfb scaling) seems to have no effect, whether it's 240x320 or 640x480. Any area within 5mm or so of the edges of the LCD will register as the edge, making "A" and several other keys on the virtual keyboard impossible to hit. Passing calibration values to the kernel didn't seem to fix anything, but it's possible I was using them the wrong way...

i have the same kind of problem on my Kaiser... i think its realted to hardware... either the housing or the digitizer...

I am experiencing the same problem on X10 mini pro. the same screen spot exactly, i have to try very hard to get z or x or shift to work. Sometimes when I try locking the screen and unlocking it back, it works.

update
so after a very long time with this problem i decided to change the digitizer and problem is gonne. visualy the broken digitizer had nothing wrong with it. The fix was fairly easy though, there is no glued parts involved into getting a new digitizer on the u20i.

Touch Screen
I just bought a brand new Cubot One and it looks more than perfect! It has just a little problem with the touch screen ( I think its the software, need ROM change). There is a dead line on the right side of the screen that touch doesn't work at all. Any solutions? Anyone faced that before? Can I fix it myself or do I have to send it back for replacement? Is there any video or guide that shows its done?
I uploaded a video on YouTube to show the problem but i cant post it yet.. (new member)
You can write "Cubot One touch screen problem" and it's the 1st one.
Thank You!

[Hardware] G1 screen issue

Greetings,
When I would try and wake my G1, the screen would not always turn on. I would have to go through the process of hitting end, flipping the screen open while hitting menu repeatedly. Sometimes it would work, mostly not. If I waked the phone, with or without the screen turning on, I could use the touchscreen. Wasn't entirely sure what I was doing of course.
Another issue was the screen "dying" while awake. Example: using navigation and the color and light would drain off the screen.
So all of this leads me to believe that there is something wrong with the cable that connects the screen to the phone body. Has anyone opened up the phone and looked around inside? Would be interested in a fix so I can use it as a remote for the house haha
Any help is greatly appreciated!

What rom are you using in your phone?
Anyway this is a software problem, no hardware.
My phone had this "problem" too with some roms.
In general I had this problem with heavy roms (for example hero roms) where swap is enable.

It did it on CM6, cm5, super d, super e, and straight up stock. Between each i would completely wipe data and cache, wipe and repair ext, wipe data again and flash.
If you believe that it is still a software problem, I have no problem trying again
EDIT: another thing is that when booting, the Tmobile G1 screen won't always show. Need to manipulate the screen to it to show.
Sent from my s=off HTC Glacier using XDA App.

If it goes on and off as you move it around on the boot/recovery screen then it is probably a hardware problem.
It's a fairly involved process to change it. You basically have do completely disassemble the phone. A little google searching can find you the factory disassembly guide (i'd post it if I knew it was ok or not).

No worries about posting a link
I'll give it a go! Thanks for the tip good sir. Will post results once I get around to it
Cheers

Just want to mention that I'm having a very similar problem with a second-hand G1. Just as the OP did, I tried several different ROMs to see if it was a software issue (stock, CyanogenMod 5, Froyo for Trout, now on TheOfficial DS). An additional symptom that mine is suffering is that the screen tends to go blank if the keyboard is flipped open quickly, which contributes to the "hardware problem" theory.
At some point in the near future I'm going to have a go at it using the service manual. Sorry can't post URLs... it's http colon slash slash mikechannon dot net/PDF Manuals/HTC%20Dream%20SM%20%28A04%29.pdf
I don't have big hands so the G1 is the perfect size phone for me...hoping to get this working reliably and then to hand off my Motorola Milestone to the husband, that thing is humongous to me. (Ironically spouse is an engineer with a Master's degree and a lot of experience with electronics but I do all the phone maintenance.)

After some minor surgery, seems OK now
I went up to "disconnect the display FPC" step on page 32 of the service manual. Then I reassembled the phone while trying to make sure that all the cables were plugged in as tightly as possible. It's rather fiddly so please make sure you have good fine manual control. (This was my first time disassembling a phone.) The "screen blanking" problem seems to be cured now although I am trying to be gentle when opening/closing the keyboard. At least it doesn't randomly go blank by itself any more.
My father had given me a set of electronic screwdriver bits for Chinese New Year, perfect timing, thanks Pa You will need the Torx 5 and 6 and a Philips 0 bit. I also used the flathead bits as levers as I didn't have the plastic lever in the official HTC manual, so the edges of the housing are a bit ugly now

Well done! I will give that a go! Congrats on getting yours working. If I remember to actually try, I'll post my results.
