Hi,
I've had my Diamond for a bit more than 2 months now.
Recently I had an odd problem with it.
The touch screen seems to be busted.
The display works fine. However, it doesn't respond to any of my touch commands and it seems like someone is touching the screen randomly, as in, random clicks on the screen.
The hardware buttons work fine, it's just the touch interface of the screen.
First I assumed it was a ROM related problem, as this happened just after I installed Shine On. So I went back to the original ROM again, but the problem persisted. Then I tried another ROM, but same problem!
Therefore I suspect the hardware.
Am I right to assume that the screen is built up of several layers? Such as the TFT screen it self, the touch part, protective glass part, etc.?
This was a week ago and I've been using my old HTC since (waiting for a reply from HTC customer service which haven’t replied yet! ). However, three days ago I tried the Diamond again, and it seems to work flawless..!
So, I'm wondering if anyone else has seen this intermediate problem? Or if anyone has suggestions what could cause this problem?
Thanks for reading
Same s*it!
Hey mate.
I am experiencing the same problem as you do. The touchscreen does not respond or not accurate enough oder in a completelly different ponint than is poninted at. Readjusting screen helps for a while, soft-reset helps for a while. Sometimes it goes away without doing anything special. Did HTC finally answer your E-Mail?
I'd like to have this fixed as soon as possible.
Edit: I noticed that this problem disappears at once if TF3D is deactivated. Let'S see about that....
Hi,
even though there are probably several other threads concerning this issue, this seems to be the most recent one.
Do you use a (genuine?) screen protector?
I do.
I suppose this problem is caused by the tremendous heat* when the device is used and a screen protector that had been applied wrongly.
I might have applied the screen protector wrongly so there are a few very small (almost invisible?) bubbles (i.e. hot air expands(?) - I don't know the technical term),
since I had to remove the screen protector once because of dust..(does the glue lose its stickiness?)
I don't know if it's because of the bubbles, but I'm quite sure it's because of the screen protector.
Has anyone noticed this behavior without using a screen protector?
(I'm going to buy new screen protectors if neccessary, but I don't want to pay ~25€ if it's not)
*= I've adjusted my screen when my device was "cold".
Edit: I've probably found the reason for this issue: there's a deformation (caused by HTC) on the bottom of the screen(at the end of the screen protector) - there's a hole without glue (but air) - everything works fine while closing the hole by pressing the screen protector on the surface of the device.
I'm going to upload a picture later.
Edit2: The picture is now online. The fact that there's a hole isn't new of course, but no one seems to have linked these two issues so far.
(Correct me if I'm wrong)
The hole wasn't that big first but it grew because of all the testing
I've cut the lower part of the screen protector off now until I have a new one, although it doesn't look that great anymore..
Edit3: Ok, it's the hole and not the screen protector - I guess I have to get a new Diamond from my provider since it's a manufacturing defect..
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!
Hello, I tried alot and hopefully someone can help me at my problem.
Mx Xperia Z had a water damage. At disassembling and cleaning the phone with isopropanol I scratched both data cables.
The phone is working again (everything) but now I have one problem. The screen is flickering at some colors at some spots as seen on the picture.
I think its because scrachting the data cables. Does someone knows for sure or with a high possibility what exactly could it be - Am I right with the data cable and what can I do?
I couldnt get the cable without display and just want my phone back 100% to work.
I would be really happy and thankful for some purposeful tips or especially for the final tip what can help me.
Best wishes
lerush from germany
ps. As seen in the pictures. Its not in every color and not in every position of the screen. The flickering is a combination of color and location on the display.
pps. The flickering is sometimes getting stronger or lesser strong depends on the pressure on the phone / backplate. I´m nearly 100% percent sure it´s the data-cable. I added last picture after prssing backplate back on the phone. What can I do with the datacable? - Is it the datacable?
i do have same problem....no a single reply to this problem....did u got any solution for this problem plz reply

You damaged lcd flex cable (the black one on the right side) while removing your battery. I think that you don't have many options, you must change that cable (complete lcd). You can try with adding some thin tape on that scratch, and try with reconnecting that flex cable (see if the connectors on the mbo r damaged). Good luck bro.
the same problem with Z1
Hi,
i have the same problem but with Z1. I replaced display with touchscreen and i can see the same effect of flickering, stretching.
In my case, when phone is working longer I have more flickering, up to the moment when i can not see anything. The back side of phone is getting warm (around NFC logo). Also i got more flickering when on screen are pictures, icons with high resolution. Simple text are almost always clear.
Is it possible, that other thing than lcd cable is the problem?
My doubt is warming of the phone and that i got more flickering with time.
Also supplier wrote to me , that they check every single part before sending. I can not notice any visual signs of damage.

I changed the screen for a new one, now is working great. Thanks!
Hi, for the last few weeks I've been experiencing this annoying crap. My screen works just fine sometimes but there are moments during the day when the screen clicks itself, literally. It's like when you put your phone under water and try to tap the screen - it clicks completely different parts of the screen in a small period of time. For example, I start typing on Swype and suddenly the swyping line moves from A to B, then stays there for a second, moves to I and that happens even when I don't have my fingers on the screen! It's really annoying and I have no idea what could be causing it. The phone hasn't been damaged by water or by falling down. It's on stock ROM, no tweaks, locked bootloader (thanks Orange...). Could it be a hardware issue? I really don't feel like getting rid of my phone for 2 weeks (or more) for Sony to get it fixed

Take a very close look at your screen for hairline fractures or signs of stress (odd colourations in a circular-like pattern). I ran into this issue when I damaged my first screen. Along the length of the fracture behavior would be very erratic, until eventually it stopped functioning and I had to replace it.
The anti-shatter film does help against shatters, but doesn't do much for fractures. I've also read that the screen can fracture itself. This is a very rare issue, but it's what happened to my first screen I suspect.
I should add that replacing the screen myself was an almost excruciating 3 hours of spudging and heating, but it is possible and could save you a couple hundred dollars. I would advise against it if you've never opened a phone before though, lots of glue and sensitive components.

I've had a screen protector since day 1 and I removed it only 2 days ago, cause I thought it was causing the problems. I have never opened this certain phone but I have experience replacing screens in other Xperias. The question is if it's really hardware related or maybe there's a software fix for that. If it's the hardware, I'd send the phone to my provider to have it replaced under warranty

There's a calibration program floating around called st21i calibrate. I haven't used it myself as it appears to be tailored for issues I've never experienced, but it may help if the issue is software related. It may also do nothing as it seems like it's more for lag issues but ya don't know until ya know.

Hey guys
I have a very strange problem with my Huawei P10
About 2 weeks ago, I noticed that two purple horizontal stripes are appearing in a 3-4sec sequence
Normally, I would immediately ask for a repair, but there's a thing which persecutes me: it only happens when I don't touch the screen for longer than 3-4sec
When there's a continuous contact with the screen (e.g when writing a message) nothing happens, everything is fine and dandy, but whenever I leave the screen for itself for 3 or more seconds (e.g when watching a movie), the stripes start to appear every few seconds, and continue until the screen goes dark or until I touch it again, but after touching it it still takes only a few seconds for the stripes to sequentially flicker again
Here's what I've tried so far (no result):
- safe mode
- factory reset
- cache partition wiping
- cord input deep clean
What may be the reason?
Hey.
It's 100% a board or Display issue. send it for repairs. but i believe maybe you've dropped ur phone. Anyways Huawei knows better.

It's quite complicated
I once dropped it, but even after that, the previous LCD worked fine, there were no errors other than broken glass, so I guess we could exclude a board issue and lean toward your second option, as now that the LCD has been replaced, the fault occurs
What's more, I noticed that if I press the Home Key, and then put my finger in the bottom right corner and hold it, I can still use the whole LCD space without the flickering (I need to press the Home Key first so that it works after I hold my finger in the corner)
It's like the LCD needs to be in contact with your finger all the time to avoid that, which has led me to an idea: would a tempered glass solve that maybe?

I can't really answer for sure but i believe if there's a Huawei service center in your city and you try to fix ur broken huawei, your wasting your time. Whatever solution u apply on ur phone its just gonna be temporary since u hide your problem and not solved it.

I still think (or should I say believe ) that there's a solution which doesn't involve another screen replacement
As for your "temporary solution" mention, I guess if I found one, it wouldn't be temporary, since the fault doesn't progress, it's been the same for a month or so when it first occured, which gives me another reason not to replace the screen and keep looking for other possibilities
I don't need a Huawei service center, I can replace the LCD myself (didn't do that the first time though), but it still involves spending money, whereas I've been looking for unpaid solutions the whole time; getting a new LCD is an extremity

You can ask them to diagnose it and tell you about problem noone makes you pay for a lcd. And after reading your message over and over (And since i repair TVs and everything with electronics inside) i think it also can be your touch or display controller ic. Mostly it could be from touch ic since screen works fine while its in touch with something. But someone has to try your lcd or mb on a healthy one to make sure. which you can't do nothing like that. or do you?
@fengels did You bought original lcd, where can I buy it in good price?
I know this problem from older galaxy series like s5. The fix for this most of the time was disable auto brightness or higher the brightness on auto brightness. Don't know if this is the same problem, but it could be a try. Also don't know which cause this strange problem. Hope it can help you

No, it's a different problem, in the galaxy series the whole screen would flicker, whereas in my P10 it's only 2 horizontal stripes appearing in a 4-5 sec sequence whenever I leave the screen untouched for longer than 5sec
Playing around with the brightness doesn't solve that unfortunately, actually no in-device settings do, as I've tried almost every single option which is screen-related, like switching the eye comfort mode on, but still no result
The main reason why I'm still looking for an unpaid solution is that apart from this one error, the phone is like brand new, everything works fine
ok, so if I understad the problem shows up after you replaced the LCD display? So do you really think is more software related than hardware? I personally would send it to diagnose and repair.

The thing is it didn't show up immediately, I had used the phone for some time with no errors before it first occured
Also, since the new LCD was set, I haven't done any physical damage to it, I've never dropped or sunk the phone
Since you guys mostly advise me to send it, I guess that's what I will have to do

While you were replacing screen, did you turn your device off and disconnect the battery? and i think cleaning all cables coming from LCD and related sockets on motherboard can help. Use thinner or alcohol and if you wanna use thinner be careful so it wouldn't touch anything except golden contacts. Thinner is dangerous and affects ur phone color and plastic parts.

I did turn the device off, but I didn't take the battery off, since it's strongly glued to the phone's body, and I didn't want to damage it
Anyway, could not taking the battery off really be the reason?
As for cleaning, I did it by simply blowing out all the potential dirt, I'm inexperienced in thinner and alcohol cleaning

I am not sure butbon some phones it damages screen. I've seen this on laptops. But anyways its done. Open ur phone and use alcohol. put 2 drops of alcohol on each socket and flat cable connectors and brush it with a soft brush. u don't want to bent any golden contact. It's last thing u can do to fix it without paying for hardware related stuff.
