In the past month or so my Dinc2's touch screen has become increasingly erratic. I don't think it's the screen itself, because anytime problems arise, a quick off and on of the display will fix things. However, the problems seem to be centered on the bottom section of the screen...weird.
The problems I'm talking about are unregistered presses, pressing one place and something happening in another place, presses happening without any contact at all, etc. For example, sometimes I won't be able to drag to unlock, but when I turn the screen off and on, it'll work.
I'm thinking (hoping) it's a software thing. I'm running CyanogenMod-7.2.0-vivow. Are there updates to this ROM? Should I just try another ROM?
Looks to me like a faulty digitiser. But try wiping and refalshing. It won't hurt. Good luck.

After wiping, should I flash a fresh version of the ROM or restore a backup?

try wiping and flashing without restoring. start fresh. if it works, then you can look int restoring.

Didn't work. Any other ideas? Not sure what this digitiser thing that you're talking about is...
EDIT: Ahh...it's hardware. Well, crap. Is there a cheap way out of this mess?
I found an "HTC Droid Incredible 2 Tough Screen Digitizer Replacement." $24.99. Is this the solution?
If you truly believe it's the digitizer, then yes, that's the way to go. I warn you though, the digitizer is glued to the LCD so you need patience, a light hand, and a blow dryer with low heat setting. I replaced one myself and managed to make a small spot on the LCD where I must have accidentally flexed it a little.
Back on topic, I believe I'm having the same issue with an Original Incredible. I turned on a developer option that registers screen presses as dots on the screen and I have two, almost constant, finger presses in the upper left middle of my screen. I'm thinking it's the digitizer, solely because the presses also occur in my TWRP recovery. Lucky for me, the digitizer is only attached to the front housing of the Incredible, so I just have to purchase a whole new front housing with digitizer attached. Best of luck on replacing the digitizer if you go that route, but you may as well want to invest in the whole screen + digitizer package if you can afford to.

Hi everybody,
I have problem with my HTC Touch Pro 2.
It was fully working until I damaged my LCD screen and digitizer.
So I ordered a new one LCD and digitizer from ebay. I changed old lcd and digitizer, booted up my HTC and everything looked allright. But problem came soon. Touch screen can't recognize my touch exactly. For example, if I click on something, digitizer solve it allways about 2-3mm higher. So I can't click on start, battery and every other click is moved about 2-3mm higher.
I made a calibration, but without any effect. I made a hard reset and than a calibration, problem still same.
And if try to make a new calibration (after first calibration after HR), I click on first cross (in the middle of screen), then up-left corner, down-left corner, down-right corner, up-right corner and nothing happens, I have to click on first cross again... and whole procedure again... So I have to make a HR and try to make a new calibration... still same problem.
Could anybody help me please? I'm going crazy, because I like my HTC and I can't use it anymore.
Is there any other way to make a calibration or how can I repair it?
ROM:
Energy.RHODIUM.29022.Sense2.5.Cookie.2.0.Jul.04.7z
(I have this ROM before I damaged LCD screen, any it worked fine)
It almost sounds like the screen/digitizer aren't lined up correctly... Just my .02.

Ok, then It seems to be a HW problem between screen and digitizer?
So what can I do now? Try to repair it again?
How can I check, if digitizer is OK? or could be digitizer bad at all?

I'm just guessing from your description. I've never actually replaced the screen... If the two have to line up perfectly, I would ensure they are lined up correctly. Perhaps try slightly moving the digitizer down...

Ok, thanks. But I can't move with a digitizer, because it is in fixed position. Maybe I can move with a screen under a digitizer, but then I will not be able to see whole screen (digitizer has a black edge/margin/border).
Any other suggestion?

Nope, all I got. Calibration always works perfectly for me - if calibration doesn't work, there certainly must be some hardware problem. You replaced the screen, unfortunately you must establish where the hardware issue lies.
I don't have any help for you, sorry, just jumping on the wagon. My touch screen worked fine for a year but is now way off (1.5-2 inches sometimes) without having damaged the screen to my knowledge. I've switched roms (from MR.X to Mighty) and hard reset. If I try to calibrate it just keeps running through the process. Should I try to replace the digitizer? I plan on getting an iPhone if possible on Sprint in the coming month but would like to sell this for at least a little bit.
To both of you guys - have you ensured there's nothing between the screen or digitizer? Nothing that is wedged on the edge of the screen...?
I know some had reported complete screen failures just from some gunk that got wedged on the side of the screen.

Thought about that, but dismissed the tiny little amounts of gunk on the edge..currently searching for a toothpick or something small to clean out the edge. Thanks for the idea! Will report back.
Thanks so much arrrghhh! Found a small pin and got out most of the dust/gunk that was between one side of my phone. Apparently that bezel side is just a little bit looser. You saved me lots of time and money! Thanks. Always helpful on here and PPCGeeks.
Edit #2: Must still be more junk because the 100% functionality just went away. Time to clean it again
Hi, has anyone replaced their digitizer on their desire z/g2? How did it go? It looks easy on the youtube vid.. have any problems? What way did you use to melt the glue? What digitizer did you use, where from?
Any info much appriciated as will be replaceing mine v soon due to 'invisible finger problem' that's driving me nuts..
Thanks..

Never done it on a g2 but should be pretty straight forward especially with a video lol. Use a heat gun to melt the glue, pretty much the only tool you SHOULD use to do something like that.
I replaced the digitizer on my third G2 after getting a refurb replacement from T-Mobile that had a black spot inside the actual digitizer glass, not on the outside or inside.
The process is very easy with the video, however, trying to keep dust and fingerprints from getting on the inside of the phone while you're trying to get it back together is a serious pain in the rear! If it's the same video that I watched, just use a hair drier blowing hot air to heat the adhesive on the inside of the digitizer and then pop the digitizer off very very slowly, because you don't want to accidentally bend the metal bezel around the screen.
You also may want to leave the original leftover adhesive on the inside, because when I cleaned mine off, light now always leaks out around the bottom edge of the digitizer, below the menu, home, and search buttons, even though I used the double sided adhesive strips covering the entire length of the bottom, so light shouldn't technically be leaking out. No biggie, though... it works like brand new, now!
Thanks for the reply.. I have seen that video and that's what I was using as a guide.. I ordered the digi today, should be here tomorrow.. the only thing I was wondering was the glueing process, as I have not ordered the double sided glue/tape stuff, as I was just hopeing to still use the original glue as I think you are saying.. I hope that works! Have to be careful like u say with dust/fingerprints etc..
Sent from my HTC Vision using XDA App
Hmm, after reading your post again, maybee I should of bought the double sided tape afterall? Do you think the old leftover glue is enough for the new digi?
Many thanks..
Sent from my HTC Vision usingall XDA App
Run over to radio shack they must have some kind of glue you can use lol. google cell phone screen glue see what info you can find.
Ok, just incase anyone is interested, got my new digitizer, followed the video, used a heat gun cerfully to melt the glue, pulled the old digitizer out, and used the original glue whilst still warm to hold the new digi in, as all of glue stayed on the case rather than on the digi, which was pretty lucky.. put it all back together and everything perfect, touchscreen back to how it should be.. cost me 17 pounds.

How was this accompilshed?
I replaced the touch screen as well and the problem persists. Plus I never ran into a part that required a heat gun did I use the wrong item?
A VERY confusing part is getting the midframe to hold to the hinge mounts. The side (black dots all down it) should overlap the stabilizer bar on the hinge. I fidgeted with it for hours until realizing it goes over, and inadvertently damaged the highly sensitive LCD screen, which resulted in me taking the whole thing apart again to replace the LCD and digitizer. UGH!
DO NOT get the cheapo digitizer on Amazon, look for one with gray spots where the menu, home, back and search keys are on the back side. The digitizers without them will not work when you swap over the white button caps on the back. I feel like this information is vital to anyone who is replacing their G2 digitizer, but most guides and videos make no mention of it.
I used a lamp to heat up the glass to remove it the first time. Took too long the second time so I used a hair dryer.

Hi, I did buy mine from amazon.co.uk, there were a few for sale,, the one I bought was supposed to be a genuine t-mobile g2 replacement (refurb I think, pressumably this just means that it was from a second hand g2 that had problems and the digi was taken out - and I'm pretty certain this is the case as mine has a thin film (which u leave on) over the back of the digi covering the tracks etc, which had a few very small air/dust bubbles under it (just noticeable when screen off), where I own a desire z, so now it sais t-mobile instead of htc, but I can live with that.
The small grey bits that you talk about were floating about or stuck on my digi when I pulled it off the main chassis. I had a look, and as far as I could work out, were possibly just for giving colour to the tiny led's that give you light to the home/search keys etc (I may be wrong on their use), but if you look closely, the tiny grey things have even smaller rectangles on them that relate to the positions of the led's on the circuit board. So I picked the remaining ones off the old digi, put them back in their correct holes and stuck the new digi in. I've had no problems (with a digi from amazon with no little grey things on it) so far, but maybee this is due to mine being a second hand original part..
Edit : Now after reading your post again, you're talking about bits that are actually on the digi itself, not the white caps that I'm talking about! Whoops. I didn't notice any grey spots on the digi itself, but I guess I must have them..

actually it says HTC on it and looks a lil bit differently than on the picture.
never the less, i replaced it really carefully and checked every connecting.
But somehow the Touchscreen doesn't work at all.
Can anyone help me ? what could be the problem ?
Wrong digitzer ?
is it okay, that the digitizer has direct contact to the frame where it is glued to ?

Hi!
I have the same problem, I have asked it already here
So you had invisible finger press in the screen, and the screen was bad responsive?
...Just to make sure my problem is digitizer problem! The service wont change it in warranty unless the problem is there all the time! But its driving me crazy! why is it happening randomly, why isnt it all the time? How could i make the screen to do this problem when i'm at the service?
So I have literally no idea how this happened. I'm guessing I stepped on my phone while I was cleaning my room but the LCD had black and white stripes going up and down when I turned the phone on, and after a reboot my screen is completely black with a diagonal white stripe on one corner. However, the digitizer works fine and the backlight works. I'm able to answer calls and use the capacitive buttons. I found a replacement LCD through repairsuniverse.com for $35, and I'm wondering if this is my best options. Any G2/DZ users been through the same experience? Many thanks in advance.
I've done it before. It's not that bad. Make sure you do it slowly in a well lit area with clean hands. You've seen the video right? Make sure you have the phone separator tool or thick guitar picks

Hi everybody I have a question regarding a screen problem I have.
Like I mentioned in an earlier post I accidentally spilt a lot of pure alcohol(the kind you use to disinfect a wound or something) on my HOX.
After a while the phone screen showed some strange grey shape on the lower right part of the screen and a bright white long shape looking like water jumping from a fountain on the left side starting from the bottom of the screen extending to almost the middle of the screen.After turning it off for 8-10 hours they grey shape dissapeared and the white remains and it doesnt look like it will ever go.
Strangely enough the HOX has no problem everything is working but I noticed that some apps are working somehow over the white shape covering it and some others like facebook seem to be under it making it visible.
I made some screen shots to show you the problem but stangely enough this white shape is not shown at all in the screen shots!!!!
Can anyone tell me where this thing might be?
LCD? Digitizer? elsewhere?
HTC funny enough suggested a factory reset to solve this and if that doesnt work(like there is a chance that it will...) to just send it to service.
I plan to play dumb to service hopping to fix this under my warranty as the phone has absolutely no scratch or anything anywhere as I never even dropped it once.
Do you think they can somehow find out what happened of maybe they will fix it under warranty?
Thanks a lot for your time reading this and I d love to have your opinions

Perhaps some alcohol got stuck between the lcd and glass...

Looks like overheating damage by a component beneath the screen, possibly something reacting to/affected by the alcohol.

When you say beneath the screen do you mean beneath the LCD as well or just beneath the glass?
I am just thinking that if its beneath the LCD it would probably not show plus the phone would have some kind of functional problem(it works just fine) wouldnt it?
Beneath the screen assembly. It looks like (possibly) some component or board has caused damage to or affected the digitizer, as your actual display seems ok.

So the service corrective action will be a screen assembly replacement or you think that something more will be needed?
Also if the digitizer was damaged wouldnt the phone use be affected?Cause the device has not been affected in anyway.
Everything works like it used to before this damage.
Send it of for repair, youll have to pay of course, how much tdo you like your phone?, that's the question.

I like my HOX very much otherwise why would I pay 428 euro to buy it?
Of course what makes the HOX stand out of the samrtphone crowd is the amazing display so of course I want it fixed.
I will try to cheat saying I know nothing about it(the phone doesnt even has a scratch) hoping waranty to cover this but if this doesnt work I ll have to pay 196 euro for screen replacement.
Although appart from that mark nothing else is affected I am worried that perhaps a screen replacement might not be enough if the digitizer is affected by something beneath it.
Do you think that a screen replacement will be enough to solve this problem?
HTC will give you the digitizer and LCD, especially if you end up paying, which will then get you a new bezel and unibody all still tapped up in protective coat, I've had it done for my phone, 160gbp.I even think you get the Onex+ version screen, gorilla glass 2.Could be wrong

Today I finally decided to replace the broken screen on my Nexus 7. Everything went well and according to plan, and when turning on the device I noticed it was working fine. However, upon closer inspection it turned out that one thin line on my screen isn't working. It's preventing me from doing SwiftKey flow, and when I tried drawing in Evernote I could see it was skipping over that part of the screen.
What could be the cause of this? I can't rule out that it's the screen part itself, but could it be more likely that I somehow damaged the LCD flex cable? I tried detaching and reattaching cables, so I have doublechecked that. I guess my question is mostly, how useful is it to try and replace the cable? Thanks in advance!

Did you replace the combo lcd/digitizer, or just the digitizer? In the latter case, you're lucky to have just a thin dead band; usually,1/3 of the screen would be unusable. In the former case, if the bezel is bent, however slightly, or there is some glue residue from the old screen on the bezel that causes the new screen to lie on an uneven surface, it would happen. I've experimented enough times to know the bezel has to be absolutely clean of everything and the surface must be 100% smooth and even. If you used strong tape on the new screen, your best bet is the multi-fix touch, as removing it would in most cases damage it.

I replaced the screen + digitizer. I looked at the bezel (luckily the tape I used wasn't that strong so the screen was still detachable) and I cleaned it up thoroughly. There were indeed some glue residues left. However, it was no use, the screen still fails in the same locations. I had high hopes this might be the cause, but apparently not.
I highly doubt the bezel was bent, because I was very careful with it. I will try out the multi-fix touch option, but I'll do that tomorrow as I'm quite tired now. Thanks for all the suggestions!

Don't know if you're familiar with the mechanics of the touchscreen, so I'm adding this for the sake of completeness. Lots of people would post problems and when you try to help, would snap back: "I already tried this and that and other things..." So if you already know, forget the rest.
I've found Yet Another Multi-touch Test (YAMTT) of tremendous help in diagnosing. When you switch from one firmware to another, YAMTT allows you to pinpoint exactly where touches do not register. If the dead band remains consistent, it's probably the screen itself. However, touch detection sometimes varies with the speed at which you touch. I've seen touches missing in some areas, which would register on a second or third or fourth pass. So, go slow in those areas, and back and forth to make sure they're really dead. Tedious process indeed, since you have around 30 variants to play with.

I took a look at that tool, and I posted the result of drawing on imgur: paste "oyIt3bg" after imgur.com (I'm apparently still too 'new' to post links, sorry about that). It is clearly one band, very consistent. I think I should probably talk to the shop I got it from and ask for a replacement. Which sucks, because this particular parts took 3 weeks to even get here. Anyhow, glad I know what the problem is now. Again, thanks for all your help, I appreciate it
Hello fellow dutchie,
I have experienced this problem on my Nexus 4, and after having replaced the LCD+digitizer I also had issues with touch responsiveness in exactly the same areas. As silly as it would sound beforehand, it doesn't seem to be the screen or digitizer. Best... to give up.
