Dropped my Thunderbolt but was able to get a replacement screen and get it installed. It worked correctly for a couple of days, but now the touch screen is not always accepting input correctly (sometimes). Middle section of the screen seems to split and act like it is getting multi touch input. Example is pressing the letter 'n' will enter 'b' and 'm' at the same time.
Other times the screen is acting like it is receiving touch input with nothing touching it. Texting or internet browsing is a major pain now, although everything else seems to work just fine. I have verified the ribbon cables are seated correctly and that there is nothing shorting out the sensors between the touch screen and the lcd.
Should I bite the bullet and replace the phone or are there other options for resolving this issue?
Most likely it's a bad digitizer. Get a replacement for your replacement, any decent shop should have a warranty. If you did it yourself contact your seller and get it replaced.

All of a sudden few small parts of my screen stopped responding to touch. When typing texts or emails, letters "T" and "G" do not work in portrait mode and "E" doesnt work in landscape. I did some research and it seems to be digitizer or moisture problem. I did not expose the phone to any moisture before it happened... I tried to do hard reset to eliminate software issues. Do you think this will be covered under warranty?

if it's a digitizer issue, then yes it should be. if it's a moisture issue, then it's water damage and you'll be forced to fix it yourself.
you should be able to, I recently exchange mine and it had an unlock bootloader just go to an AT&T customer center (assuming you have warranty with them) they'll swap it right up. (Back up your files, contacts, etc. Cuz they are not gonna fix it but replace it)
I just got my phone replaced for the same reason.
If there's no water damage etc., definitely get AT&T/Motorola to replace your phone for you.
I think its starting to happen to alot of people... mine went out a few weeks ago... but I'm at school and haven't had alot of time to send it in... thankfully I have an older phone with me.
best chance is you have to replace the digitizer, i tried everything i can to fix my but nothing worked, so i had to replace the screen. Motorola should follow Nokia and did some testing before selling the phone
Having a problem with ALL keyboards (swift, flext9, stock) when tying to type letters on the bottom row (z,x,c,v,b n,m). When trying to input these letters the phone will input the letters directly above. I've read it can be a software or hardware issue. I have pulled the battery, wiped cache, wiped dalvik cache, and ran a superwipe. I was going to try and clear data for the stock keyboard (htc_ime) but cannot find it under Application-Manage application-All. I also tried looking under Application-Manage application-Running; what I found was Touch Input but no options to clear anything. Where is the htc_ime found?
I also noticed when in the dialer that I cannot input *, 0, #. Instead when I press these keys it will input 7, 8, 9, the keys directly above.
I am slowly beginning to believe this is hardware related, but what is weird is that yesterday after wiping cache/dalvik the keyboard worked normally. However, after some time passed, it reverted back to having issues again.
Is there anything else I can try? Could it be possible that the ribbon for the digitizer is loose rather than the digitizer just failing?
Maybe something you did mest up your Calibration you can check by going to.
"Settings ---> Language&Keyboard ---> Touch Input ---> Text Input ---> Calibration tool."
And see if that fixes your problem.
Seems to be known HTC problem for years and they haven't fixed it.
install a free app called 'Draw' from the Play store. When you open it the screen turns black and then slide your finger around and it will leave a line. This will show you if all areas of the digitizer are working. Press your options button to get the menu.
On mine Evo3d the problem started with it randomly starting to start programs or even make a few calls. I now figure that is from the digitizer acting up and behaving as if there was touches in the problem area which happens to cover the stripe of screen about from 1 to 2cm up from the bottom. 0 to 1cm is ok, then 1 to 2cm is bad, then the rest of the screen is ok. What has happened over time is that section of screen no longer seems to trigger phantom touch behavior but it does not register horizontal movement. On the Draw program vertical lines draw fine, horizontal ones leave nothing. Lines drawn at an angle skip and leave vertical lines across the defective area. Unlocking the phone with the Sense ring became almost impossible and I missed numerous calls. Even now that I switched to the slider unlock it is almost all in the bad zone and I have occasional problems getting the phone unlocked.
References are phone held vertical.
The problem originally happened on the stock rom, rooted. I figured it was a software thing so wiped the phone and took the opportunity to install LeeDroid. The problem still exists.
Using the calibration tool or any of several other suggestions does nothing.
Oddly touching keys works for typing and even SlideIT keyboard works though the line it leaves jumps around like crazy. I can't play some games that require that area of the screen. On programs that allow rotating I can usually get it to work as this moves the problem to a different area.
I really don't like friends with iPhones and other brands laughing at my phone.
I started searching Google and there are a LOT of other complaints going back several years and on numerous models, but no real solution. I am disappointed that the response from HTC seems to be that failures are within what they consider acceptable because the solution seems to be return the phone as it is a hardware failure though they do not admit to it. Some people report having the problem within a week on a phone that they left completely stock to see if it really was a user software thing. Some have had the replacement phones quit within a short time as well which makes you wonder if they even replace the digitizer when they recondition them. The actual complaint probably never makes it to the tech so if it works good for 10 seconds out it goes.
I am not very happy with the 'return it' solution since I have a $25 Zagg protector on the screen I will lose and it takes time to set up a new phone, and from the sounds of things the replacement isn't a guaranteed fix. Finding out that it is a known quality control issue that is still present after numerous years has soured me on HTC. If it was a rare occurrence I could understand but not when I read so many reports.
My last flip phone was indestructible and from Samsung. After all the hassles with crappy charge connectors and keyboard contacts from dust at work on a Motorola flip it was a true pleasure. I intend my next phone will be Samsung.

when you need to type those keys in the dialer try turning your phone sideways as the dialer should rotate.
{ Disclaimer: the following text is my view about this problem. I'm not in any way responsible for any damage }
As there is very little info known about this phenomena I will try to explain it. I learned a lot of disassembly guides and by visualizing it (settings-development-show touches)
Ghost touch is a strange phenomena of various types and is due to a hardware fault between the mainboard connector and digitizer screen, I'm therefore trying to clarify it by categorizing them in three groups:
1. Small; Screen is unresponsive. 1 lock/unlock and it works again. Almost perfect. No need to replace screen. Most common.
2. Large; Same as 1, and often up to 5 touches and the touches are often moving/pressing parts of the screen. This can become a very frustrating period. Messaging apps and settings can be messed up by these touches. Often a lock/unlock will fix this temporary. A full screen replacement is recommended
3. Unworkable; Same as 2, and the lower and upper part are not working anymore. Notfications bar can not be pulled down anymore, typing become a nuisance and it not possible anymore and you curse your phone. Also it is not even possible to insert your pin, unlock your phone etcetera. This problem will not be fixed by a restart/reset or lock/unlock. A full screen replacement is essential.
Many people say this can be fixed by software settings, however this is a hardware fault. I tried many different roms and I encountered at all of them. The only fix that can be done to fix this is replacing of the full screen as it is not possible to apply/remove your digitizer.
For a long time I thought it was due to the degrading digitizer or something, in fact it is probably the connection between the and the mainboard. The screen has two digitizers: One for the touchscreen and one for the home/settings/back/search buttons. For some reason this last one did not cause any trouble. The first one has a flex cable from the upper part of the screen leading toward a small hole and heading to the mainboard. The problem will probably reside in the part between the digitizer and the small hole. Here, just above the screen, the flex cable is folded 180 degrees. This fold will cause the problem as it is very sensitive. Mine has a very small damaged part, the copper parts are visible. The cause of this is due to the rubbing of the bezel just under the speaker.
How to fix it?
Buy a new screen including digitizer (often HTC & Sprint branded) and make sure you protect this part as much as you can.
EDIT:
I re-inserted my old LCD display with a bit of tape around the damaged part. Since then I haven't had any ghost touches.
Mine was ghost touching so bad it was completely unusable for a few days. I was thiiiiiiis close to buying a new phone, then one day it just stopped and hasn't done it again since. Very strange. Anyhow, I will be replacing it with an s4 when the price comes down to $100 for us SERO users.
Ghost touch
Nice explanation, and nice 3 lvl sorting but, tell me one thing... I have experience with lvl 1 and 2 (two different phones) and for both of them simple ROM change / reinstall helped to solve this problem.
For ex. I had JB [ROOTBOX] ROM since the last week.. ghost touch problems were getting worse and worse with each new day yet lock/unlock still worked quite well.
I decided to test new JB MIUI ROM and like a magic touch my ghost friend is gone since than, but I am afraid he will return more powerfull than ever... oops that is a different story. However my phone is now working fine ... no ghosts detected.
So please don't tell me that this problem is only mechanical problem ( due to ROM change / reinstall worked multiple times). Actually I am pretty sure that is software problem which is supported by hardware hitches.
My friends "ghost story" is pretty similar.. but he reinstalled back original ICS ROM.
PS: I don't want to start flame war with this reply. It is just mix of my experience and opinions.
I just got done replacing my broken screen on my LG G3. I replaced the whole front panel and just transfered the guts. Everything checked out fine after replacement until i typed my first text message. row A-L will not goto screen unless I touch nearly inbetween the middle of the row beneath it. q-p work fine as well as z-m. What really has me boggled is that the screen accepts touches there in virtually every other app/drawing. Just the keyboards aren't allowing touch in that specfic row. any suggestion?
Found a few more bad section.. Pulled the back loudspeaker back out and tried reseating the cables and still had same issue. They're sending a replacement for free.
This was my first screen replacement, but not my first time dealing with small ribbon cables. All cameras function fine, hoping it was a defect in screen and not my screen changing abilities.. Any tips for the next one would be appreciated. Would like to have a fully functioning phone again sometime. This is nearly more frustrating than the broken screen.
I am having same Issue

Hey just curious if your issue has been resolved.... I am having same issue, but i took mine to a computer store i have been dealing with for years. about a year ago they started doing cell phone repairs as well. I had them replace my cracked screen on my LG G3 and that same row of text if off for me and there are a few other spots i have noticed are off as well .... very frustrating... Anyway the place I took it to has replaced 3 screens hoping they were getting defective parts.... they just called to tell me I can come get it but they were unable to repair the dead spots without going further into replacing boards or something.... I dont know... It is weird though cause you can get the dead spots to work sometimes by very lightly touching or just touching it in just the right spots like a calibration if off....

A review on G3 LCD's on Amazon reports the same problem "I installed the screen and immediately my wife mentioned that it seemed to have "dead spots" when she was texting / playing games. I noticed it myself when I tried texting myself as a test. Several of the letters on the keyboard just wouldn't register very well. She went into the settings and ran the "motion sensor calibration" test under general settings>gestures. This has resolved the touch screen issues. "
I don't see how that would fix it but I guess it's worth a shot.
Due to damage done to the LCD of my S II I had to replace it. So I did that and I noticed two very serious issues. The first being the unresponsive touch buttons to the bottom right and left of the device. They were also not illuminated, there was also no evidence to suggest they were not connected correctly.
The second issues and by far the biggest is the unresponsiveness of the touch screen. When I enter my pin the first touch takes a few seconds to respond, then it proceeds to work as normal until the phone is unlocked. From that point whenever I try doing anything it behaves erratically. For example when I dial out it is painfully slow to respond to the inputs given to the touch screen.
Is there are way to address these issues and remedy them if so how could this be done.
Looks like a bad piece of hardware. Did you get the spare part from a trustworthy store? About the softkeys, you could check if the connector is connected correctly. As a workaround, you could use onscreen buttons.
