Hi folks,
I'm having some screen issues.
There is a vertical band on the right side of the screen that isn't registering any touch input. I'm currently running CM 12, but I've tried installing a stock variant and the problem persists.
This all points to a bad digitizer, but the affected part of the screen seems to work fine in recovery and on the lock screen.
I'm completely stumped. Does anyone have any advice?

Return to stock and Warranty!!!
I have a similar problem, but it seems sporadic. I get "dead spots" on the screen where it won't register a touch until I either change the screen orientation or turn the screen off, then back on. These spots happen everywhere, though most often along the side of the screen (all sides, and occasionally towards the middle.) pushing harder, long pressing, etc. doesn't have any effect.
I turned on show touches, so I can tell when it happens. I can see that it seems to register the touch initially, but the touch quickly disappears (almost like the touch area there crashed) and won't come back. If I touch somewhere else and drag my finger, it registers through the "dead spot", but won't highlight or select anything. A tap isn't registered, but it can follow my finger through it.
I also have another issue where the screen registers a touch, but the device doesn't do anything. This most often happens when hitting the home button. The touch registers and the button even lights up, but nothing happens until I hit the button again.
A factory reset didn't help.

This thread is not about the digitizer unresponsiveness that everyone else complains about. I'm writing this bcause I have discovered that a strip of the digitizer that becomes unresponsive/dead after replacing it.
If you replaced the digitizer could you try different ROMS/Firmwares and post results here?
I have several problems:
1. The screen is unresponsive at times (This is fixed by flashing RUU and updating through HTC Update)
2. In the middle of the screen there is an area that does not register touches
3. The digitizer won't register more than 4 fingers
To address the last issues 2 I have provided images:
Using one finger on the screen (registers OK)

}
Using two fingers on the screen (registers OK)
Using three fingers on the screen (registers OK)
Using 4 fingers gives nothing at all, not even 3 inputs
Placing finger in the dead zone
I have determined the dead zone to be around this area:
Looks like a specific hardware problem to me. I tried that app and it works fine. I'm able to get up to 4 touches
Have you replaced your digitizer? Also do you have the dead spot that I demonstrated above?
happens to most sensations with replaced digitizers u have to get one that has the same s/n as the stock one

Yeah but others don't have dead spot

Did this ever get resolved? I am having the exact same dead zone after digitizer replacement. I did use the proper replacement part.
I have the same problem, my digitizer was OK, and then, suddenly puff, I have a dead zone ;(
How to fix it?!
My i897 captivate goes straight to a white screen. When I press the power button, the screen instantly turns white. When I insert the JIG, the screen instantly turns white (odin still recognizes it but all actions fail). With the JIG in first then battery inserted, screen instantly turns white. I soft bricked the phone a couple of weeks ago and loaded UCKF1 because it was the only firmware that I could find that didn't have a broken download. I'm not sure if that has anything to do with it or not.
Does anyone have an idea as to the problem? I wouldn't think the LCD would go bad at random, and even so, how would that prevent odin from completing a task???
Here's a video of the attempted boot: youtu.be/XzXVv6wf9V4
This is the screen from ODIN

I took the phone completely apart and cleaned the screen contacts with alcohol and wiped it clean, same result. I found another post on the net of the same problem "fuzzy color dots" describes it perfectly.
Yesterday morning my phone was working great, then all of a sudden about an hour later I noticed that the touch was behaving weird, I was having a hard time unlocking my screen and also from time to time it's doing stuff by itself. So I downloaded a "touch screen tester" and swiped my fingers all over the screen and noticed that there are two horizontal "rows", one on the top and one on the bottom of the screen with a height of about 1 cm which doesn't work properly, when I swipe my fingers across it only registers small dots all over it. Also, sometimes in this touch screen tester there's a thin horizontal line which appears on top of the screen, which means the screen is randomly "fills dots" by itself.
I checked the LID and one looks pink to me, the other white. I haven't submerged the phone into any form of liquid, so I'm having a hard time believing this error is caused by water. Should I send the phone on warranty or should I try something first? I've heard that warranty doesn't cover cases where the LIDs are pink...

I have same issue with my Z3 dual. 1 line on center of the screen doesn't work and touch screen sometimes work weird - spontaneous touches by itself. I send phone on warranty and for now i have info that they repairing it. I attached my screen test.
UPDATE:
I sent the phone on warranty to Sony. They sent me a new phone, I got it yesterday. Super happy with their support, was without my phone for only 4 days.
I've tried several keyboards that allow swiping and they all malfunction when I try to use them. They work some of the time, but very often the swipe trail will veer down to the space bar in the middle of each word. This happens on the stock Samsung keyboard, the Google keyboard, Swiftkey and Swype. I'm guessing it has to be a screen problem, but have no idea how to troubleshoot or fix it. It's out of warranty by about six months, but it's in perfect condition otherwise. Running rooted KitKat.
Any ideas?

You can check the touchscreen function in Factory Mode.
Use calculator to enter the code:
(+30012012732+
In Factory Mode, then enter
*#0*#
Your tablet will have a menu of many tests, including the touchscreen test. Use BACK button to exit testing and factory mode.
This is an example, if all are green, it will pass and exit the test

Hi guys this is my very first topic. I have been using this phone for about 6 months and this problem started a few days ago and it's being annoying. Hopefully someone here would know what can I do.
The screen sometimes gets stuck just like freezing and doesn't respond to any kind of touch well the only touch working is if I hold the home button and it only vibrates. The way that it gets back to normal is to press the lock button and unlock the phone again, sometimes it takes a while to unlock it is like it's not responding, after a few attempts it gets back to normal... since yesterday this problem is more frequent so I am here hoping that some kind wisdom person could help me. And the other thing is that when it's stuck the screen change colours like multicolor it could be the entire screen or just part of it. Here some pictures of how it looks I don't know if it's firmware or hardware

You know, to me it sounds like there are an app, or a few that are not behaving when loaded, and clogging the CPU. As you can, take a look at the apps you are using, and see if you can whittle down the ones, and or uninstall some that may seem the culprit.
If you have a backup, perhaps restore to an earlier time when the phone was operating smoothly, and slowly . . . slowly over days or a few weeks, restore an app or two, and see where it becomes poorly functioning again.
Also, look in settings/Battery etc and see what apps are running when the unresponsiveness occurs again. Write those apps down, and as time goes for a few days/week, see what the common denominator apps show up.
Backups are a wonderful thing.
