Touch Screen

Hi guys I've got a HTC Ignito and Id like abit of advice the touch screen on my phone seems to be acting up as u can press on the left hand side and it will detect pressure but only the top and bottom 5mm will work properly the rest it will activate what is on the opposite side or will do nothing.
when Ive tried to calibrate the screen it just constantly repeats the calibration process non stop but if you do a hard reset it will start working properly but as soon as you reset phone it messes up again.
Any one any ideas is the touch screen broken or is it another problem its got the stock rom on it
Sorry for the bad structore of post feeling abit tired as been up for hours annoyed at my phone.

I noticed a simmilliar issue starting a couple of weeks ago. Looks like the X-axis of the digitizer starts to die. In my case it only detects touches in Y direction, but not in X.
So far it only appeared under hot condition like sunlight or constantly running device in craddle. After cooling down it always came back to normal behaviour (so far)

Cheers bud for the reply. Its weird tho as its same as yours as it will detect the Y axis movemnt as when i hadnt hardrest it you could minamise the clock but that was it. Simalar problem happened to my grandads orbit and acted like urs then got progressivly worse over a few months.
I wonder if anybody knows if it would be sortedby getting a new touch screen.

HI...
Hopefully we are not the only ones... But yeah my MDA Compact (Diamond on T-Mobile UK) is doin the same thing. Like you guys, mine has staterd to get worse, before it was just a few edge icons that i could'nt press..but now sometimes pressing the screen anywhere does nothing, all i can do is scroll up or down.
Axelpix... you make a good point about temp...mine gets quite warm when charging on the USB. I will try to see if this is causing the problem.
Any info on fix would be greatly welcomed.
PS i'm running the Windows 6.5 Energy ROM. 14/07/2009

Hi guys least im not alone I think the only way to fix this problem might be to replace the touchscreen im just looking to see how much it would cost to buy a new one and if its easy to just replace the screen or if it comes attached to the lcd screen like on the orbit

continuous request to calibrate the screen
Yes, I have experienced this when i switched the handset on for the first time after purchase but it went off when I forced a restart to the handset.

[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.

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.

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!

[Q] [HELP]Ghost Touchscreen Presses, Constant!

So my phone was fine about 2 hours ago, then I took a call an hour ago and since the call ended my touchscreen has been going crazy. It's rapidly clicking the top and the side of the screen. I now have a completely new lockscreen with new widgets and a brand new layout with tons of app shortcuts haha. It even managed to change things I didn't know how to change!
My phone is completely unusable. The clicks happen so fast that if I do manage to unlock it, every app I own starts opening.
Anyhow, I looked around and all I found was a grounding related screen issue on other phones like the nexus4 and lg g2. Since the XZ is sealed thats not really an easy test!
Can I get some suggestions?
Tried so far:
Cleaned screen
Power Cycle
Factory reset
Flashed stock FTF
I'm assuming my next step would be to try replacing parts, but I have no clue which parts I'm looking at. I have a c6602 model XZ
Worst part, I have a phone interview first thing in the morning and this is my only phone
TL;DR
Screen spamming pressing @ top center and mid left, factory reset had no effect.
PS: Phone is not mistreated and hasn't been dropped.

next step is to flash a tft file,if that didnt work i guess your screen is screwed,btw my friend has a x2 and its kinda a problem with that phone

I reflashed the rom via sony's updater. It's still broken. I couldn't get adb connections to work because they required verifying the connection. I'm assuming the sony tools ignore this step.

I think this is the piece to replace, can anyone confirm?
edit:
looked at the replacement process, looks like a full lcd+digitizer is a better idea as the screen is gonna break if I separate them. always something. anyone know a good quality replacement?
touchscreen no longer responds at all, spamming touches have stopped.

Screen is scrolling in chaos (Awful bug)

So basically, half year after a purchase the image on the screen started to scroll in chaos - very buggy and impossible to use of course.
It began after I left the watched at home for couple of days (they still had juice when I picked them again). Painfully I managed to proceed with a factory reset and it worked... for 24 hours or so.
I decided to turn them off and went for a business trip leaving the watch at home. Much to my regret when I got back they still had the issue and moreover, now even the factory reset doesn't help.
I did not try to flash any ROM yet since my bud had bricked his watch during this process and I wish to avoid that at least for now.
I also would liek to notice that I did not spill a drip of water on the watch neither did drop it.
Had anyone saw anything like that? what it can be? software or hardware? Any advice would fit. Thanks in advance.
PS I cannot go to warranty service since I've bought them abroad.
PSS added: Forgot to mention - the screen behaves like that EVERYWHERE - watch faces in ambient or normal mode/ apps/ settings - everywhere.

anyone please?
Edit: So I flashed the the leedroid urban and the problem is still there, I assume it is a hardware issue :'(

Okay, Just FYI the problem was hardware - with the motherboard. I've changed it in LG service center for ~80 USD

Questions about my cracked screen

So I'm curious, my screen is cracked and I'm pending a replacement and I was wondering if replacing the whole display is absolutely necessary, it was dropping from a whopping 8 inches and got a nice cracked corner , well when it came to it it made me upset but I went back to playing cod mobile , but then I turned off the display , and turned it back on later and realized my screen was discolored and wacky which I would assume points to a bad amoled ? Is that correct , it still works after a reboot but I don't want to keep the display on 24/7 due to. Burn in / batterlife issues etc I was wondering if it is possible to find some kind of software trickery through rooting perhaps or idk , my question is what causes it to work perfectly fine after booted and then go wacky when turning the screen off and back on

Seeing as the display panel itself is probably heavily damaged. There is nothing software can do to help rectify this issue for you.

I'm not looking to fix it with software moreso I was asking what causes the display to work perfectly fine until I turn the screen off and back on , and if there's a way around that like perhaps refreshing the system ui or some kind of quicker restart I can do with root or perhaps someway of just keeping the screen full black and turning the screen off without actually turning it off, I'm sure there's a few way to lessen the issues crap before I order the screen, I mean it's just a small crack in the bottom right corner

youd be surprised how often that happens. Go to sammobile.com/firmwares and download the latest firmware for your phone and flash it in Odin. Use the HOME_CSC to avoid factory resetting the device and see if that helps (probably wont) but at least you wont have to set it back up to check. It will be fairly instant gratification. If that doesnt work, flash the CSC, which WILL factory reset it. If that doesnt work, bad display

Replacing the whole display is not necessary no.. HOWEVER, it's much much easier to just replace the entire screen because most people don't have the correct tools to remove just the glass and even if they did it's still terribly hard to do perfectly! If the colors are not permanently messed up and rebooting seems to fix it then it's likely that if you update the phone it'll correct this issue but it's not guaranteed because the screen is cracked and the problem could be from the crack itself.
