So I finally replaced my cracked screen and I've been having issues with my new digitizer. It's one of the LG digitizers, not the ones that say T-Mobile at the top. When you touch the extreme left side of the screen, it acts like you're touching the extreme right side of the screen at the same time. It's very weird - when I try to capitalize, it also backspaces, and my a's all have l's after them - stuff like that. It's like that all the way from the top of the screen to the bottom.
I got in there and cleaned a couple of specks of dust that I had accidentally left between the digitizer and LCD screen and it didn't seem to help. I used compressed air to clean the contact where the digitizer ribbon cable connects to the motherboard and tried to get the ribbon cable itself to sit under the motherboard nice and straight (I had a little trouble with it the first time and it could have been crooked, I guess, but I'm not sure if that would even matter.) I've also tried soft reboots, removing the battery, full wipes, and even have experimented with a few different ROMs. Acts exactly the same.
What do you guys think? Do I have a bad digitizer or is there something else I could try to get it to work properly? Thanks!
I buy broken phones of Craigslist and fix them. I have put digitizers on 4 g2x as of yet never had that problem. I'd make sure the connections were nice clean and seated correctly. I see you've done that so my conclusion is that you have a faulty unit. Run a calibration app and see if that helps

I had bought a digitizer with the LG logo on it and it was not as senseative to the touch and as well when touching the left or right sides of it where off a little. I used the ones with the T Moble logo and all works like new.

Hi, my screen cracked, so I got a replacement digitizer and installed it. When I reassembled the phone, it worked fine, except the buttons at the bottom (home, back, etc.) and the bottom 15% of the touch screen do not register. The rest of the touch screen works fine.
Do you know if that part is connected differently from the rest of the phone? Or any other reason it might be broken.
This may be dumb on my part, but my package didn't come with adhesive, so I used superglue. Could that be messing up the sensor somewhere? Or is it not likely that?
Any thoughts/comments would be greatly appreciated.
You probably got some glue in the wrong place. I used 3M double sided adhesive, that way I could be exact with the placement

Hah what he said.
You should never use glue of any sort on electronics. If the manufacturers don't do it, then you surely shouldn't.

I have replaced it but with a terrible unresponsiveness that still exists for a short period of time after screen activation. The process is a bit in depth, though.
You need to rip up the phone from the back to the front. torx screws in the back come out, the plastic battery tray comes off, two circuit cards come off, unplugging the ribbon cables. The rest of it is a very gentle prying to get the double sided sticky tape separated from the digitizer and remaining case. you will need fresh tape to lay down so it gets a good seal, and I recommend latex gloves to keep fingerprints out. Dust free environment/do it in a plastic bag as well. Kind of a pain to keep the digitizer and LCD free of debris. I am still trying to figure out what the hell is causing the screen unresponsiveness... maybe a grounding issue.
So I received my new digitizer, and it is broken already - I slid the ribbon between the chassis and LCD the wrong way, and in trying to pull the ribbon back out, it snapped so my Sensation remains in pieces while I get a new digitizer. Also bought a roll of 2mm 3M tape to seal the digitizer back too!
The disassembly isn't complicated, but it is fairly involved with lots of delicate ribbons.
What sort of unresponsiveness are you referring - is it always, or just when it's on charge?
The phone is almost completely unresponsive immediately after reactivating the screen. This could be after it disables the screen via proximity sensor for a phone call, or securing it and trying to use the lockscreen. After swiping my finger across it for several seconds it works perfectly, however. Either seems like a software recognition or a grounding issue, as I'd imagine the finger swiping is slowly building a charge. At least that's my theory so far.

I replaced the digitizer twice so far. Both are unbranded "HTC" labels, my original said HTC and T-Mobile in the right. Also different serial. Same unresponsiveness as well. It has to be something else.

Its either the wrong digitizer for the model of phone (Europe/USA/fake garbage) or something else is at fault. Le sigh.

Yeah, I have been reading and some other people have had similar problems. I asked the seller of the digitizer and they said they have not had any problems like this before.
I think I'm going to sell the phone soon, will buy an HTC Desire or Desire HD for a few months until the Sensation XE comes out.
I also want to sell this phone. In its current state I can't see it fetching more than $100 though... Half the purpose of a phone is quick reference, not a 10 second frustrating unlock frenzy.

Fairly unrelated, but do you thing my phone is in need of a new digitizer or an LCD? Everything works fine, except for those 3-4 cracks that don't look so great.

Yeah, that's a digitizer crack. I wouldn't bother replacing it...
I just replaced my digitizer and I'm getting the exact same behaviour. A phone shop also tried two of their panels and they also exhibits the response issue! However reinstalling the broken original digitizer works!
How can all three panels I've tried be faulty? It must be something else.
I can answer calls but I have to swipe rapidly across the answer key. It sucks and if replacing the original makes it work then its a model number issue. Probably the wrong digitizer for that phone revision.

I repair cell phones for a living and have done the sensation digitizer twice. I now turn them all away.
from what I have been able to deduce, something about the space between the digi and lcd causes the unresponsiveness. try using a little more adesive, maybe a layer on a layer, it may work a little bit better

Thanks, I'll give it a go, I suppose!
Have you determined that it is more space that makes it better?
A bit of Googling suggests that many struggle with the unresponsiveness, but I suspect that there might be two separate causes here. Some report pretty random unresposiveness, and it helps to restart the phone, and apparently fixing a bad ground connection between the phone and the back cover fixes the problem. Then there are many who report that it has happened after replacing the digitiser.
I've just replaced mine, and every time after the LCD is activated, the screen is very unresponsive for 15-20 seconds, and then everything is just fine as long as the LCD remains on. Is this exactly the same behaviour everybody else here has seen after replacing the digitiser? The most irritating bit is that it makes it hard to answer a phone call in time.
I disassembled my phone once more and put it together again making absolutely sure that it was done properly. No change. I haven't glued the digitiser properly yet, though, since I'd like to get confirmed that it's working before I do something which is hard to undo. But I've tried different spacings between the LCD and the digitiser (though this is a bit difficult when the whole thing is partly loose), and I haven't really noticed much difference. I've kept much of the original glue, which isn't very sticky anymore, which means that I probably have a bit of spacing already. Any chance that the responsiveness gets better with as little spacing as possible, has anyone tried that?
Please keep posting reports on both what doesn't help and on what seems to improve the situation.
I wonder if it's like the iPhone 4. Many people complained about the proximity sensor not working anymore once the digitizer was replaced. Either way, I think I'm going to suffer through a couple months of this and buy a new ice cream sandwich phone when they come out. :/

I got one, it went in all right, but was a pita to get the oldscreen off. Its pretty much glued on, has an adhesive gasket, and requires breaking the old screen to pieces separateto . The new screen never came with the outer seal, but i haven't had any issues yet. Its been in about two months.

I replaced my screen and the LCD. They are pretty tightly glued together but my glass was fine, it was the LED that was shot. I didn't watch the video but I can give you some of my experience. I got the replacement from China. It came with magic marker blocking out the 2 logos. It was on the plastic covering and there they were when I removed it. I didn't watch the YouTube I was watching past the point where he said press anywhere its broken anyway. The next sentence was "except here". I can tell you if press there you will hear an 8.95 snap. Its the power strip to the lighted home buttons. So I put the screen on and waited for it to arrive. I also got some 2mm double-sided tape this time. I knew to get it really hot also, even though I hadn't really pressed it home. I looked at the speaker hole and though that would be a good place to grab- DON'T. It snapped off the top part of the replacement screen. I thought oh well I might as well plug it up before I trash it. I lucked up and it didn't get into the LCD-YET. I'm using it now and there is one crack in the glass but a perfect picture. So, buy 2 or 3mm tape, do not press on lower right side where you see copper. Get it hot and then get it hotter- hairdryer. Take your time and remember the connectors. You understand that what you had a link to is just the outer glass and if the LED isn't broken you'll have an interesting time separating the two.
Oh, I put electrical tape where the top glass broke and its underneath the top of the plastic protector I bought. You'd have to be looking for it to notice. Sometimes you're the squirrel, sometimes the nut.
Good Luck

SMh... broke my digitier/lcd on my One X today!
Was gonna replace my back housing because it was cracked and had scuffs to put a white one on,
but when I was doing the first step I went into the wrong slit and slid my tool in between the LCD/Digitizer!!
Only a few centimeters from the edge, guess it was enough.
Now the screen doesnt turn on AT ALL!! Phone still boots and capacitive buttons light up and vibrate
I'm not sure where to start, I hope I can get it to work still but I dont know what to try now.
Im a noob, but the only thing I can think of is to dissamble the whole phone and then
blow dry it and separate the LCD/Digitizer and put them back together after inspecting.
This happened by sliding a guitar pick in between the LCD/Digitizer.
I only went in a few centimeters from the edge until I realized I was doing something terrible wrong.
I was trying to disassemble my One X.
It still works, I plugged in MHL adapter and it works, could navigate normal, just that the LCD doesnt turn on.

B) Sell it for as much as I can? $220?
C) Try to get AT&T/HTC to replace it even tho I rooted 2.20?

I did the exact same thing you did! That's why I've got two HOX now. I had to purchase the LCD/digitizer combo. All fixed now. I still have the digitizer screen on my desk. Sucks I know.
Sent from my One X using xda premium
you can try that but doubt it'd fix anything. Plus the LCD and digitizer are seriously bonded together tight so it'd be hard to take it apart fully without breaking the glass. I've replaced my LCD/digitizer twice, and while it's not impossible, it's still very tedious and risky. So if your gonna do it yourself I'd suggest making sure the place you get it is atleast somewhat reputable so you don't get another faulty screen, and don't use super glue to bond the LCD to the housing! (lol that was what I did with my first screen and it destroyed the screen). And be prepared to be left with some more scuffs on your housing. Otherwise sending to HTC shouldn't be a problem, even with root I think it's fine. It's just a screen repair, its not like root could cause really screen damage. Good luck though on whatever you decide.

thanks for the reply, um do you think HTC would fix for free if I play dumb and say one day it just stopped turning on?
I've decided not to try to separate the LCD from the digitizer, way too work.

alright good to know! I prefer it to say HTC anyhow since im not even with AT&T! Im T-mobile!
so you really did the exact same thing as me!? guitar pick in the wrong hole!?
How far did u push in and try to separate it til you noticed u messed up BIG TIME?
I was in denial for a good 10 minutes =( still kinda am... smh
I went a little farther than you and got angry though. Totally destroyed it. Lol! Couple things. Make sure you get the adhesive strips. There is a metal casing that goes around that LCD that likes to pop out if not glued properly. And I got mine from repair universe. Not perfect but pretty cheap. Only issue is captivate button lights don't transfer over, and I had to silicone the edge of the LCD to the digitizer cause it started getting dust between them. Pain to say the least. I taken these apart enough now. I'm comfortable with it.
Sent from my One X using xda premium
u bought the LCD+Digitizer and the capacitive buttons still didnt turn on? Hope mine will work.
Also can u point to me which YouTube tut was the most helpful for you?
I wish there was some way to fix the LCD I have now tho, still in good condition aesthetically =(
Yeah it sucks that most newer devices really bond the LCD and digitizer tightly. Once (if) you take it apart you'll realize what we mean. Its possible but very unlikely with original screen. And taking the LCD off the housing is near impossible to do without breaking the LCD in my experience too. So make sure to get LCD+digitizer. And as far as sending it to HTC, I'm sure you could try but once they figure out what you did I'm sure they'll charge you (why wouldn't they? ). There was an amazing YouTube video made by some company (I think it was irepairfast) that I used but after many people complained about their service here on their one x, they removed it. So sorry, just look around for some good ones.

I agree with what xaey said. Depending on the LCD/screen you get the captivate buttons may or may not have the little fiber optics on them. I just went with the cheapest one I could find cause I'm a tight [email protected]%. There are NO good videos that I could find on tear apart and none on putting it back together. Take you time and keep an inventory of what you do. I lost a screw and its still missing inside the repaired phone.

When replacing it, just take them optics out of the original, it has very lightly adhesive but it should come off easily and then put them on the new one if it doesn't haven't them already, it should still be a bit sticky to do so. Another problem is possible light leakage (you'll know what I mean if it happens, basically more light shines through than just on the buttons). This happened to me, which is why I don't keep my capacitive lights on. Worst part is you won't know until you turn it on unless you can connect the screen to circuit without bonding it to the housing yet.
Sent from my One X using xda premium
alright I'll try that if it doesnt come with capacitive lights. will attempt to replace it next week. I hope I can do this correctyl!!
Well put xaey. I tried to transfer those over and there was way too much light bleeding from the side and bottom. Plus they were a pain to get in there. I tore that thing apart 4 times. Lol trial and error. So I just put some sealant over the captivate area. Unfortunately that does not disable the lights to them.

So my g2x front screen glass was broken. Replaced it with a new one and after reassembly and powering the phone on, its responding to all my touches but the screen is very distorted. It looks like a 90's crt tv going crazy, with the noise on the screen if you know what I mean.
Any ideas? Or did I just seat the digitizer wrong or the ribbon on the screen is off by a pin or two?
Try resetting the connections. If it's still like that it's a low quality digitizer and I would try to return it.

If the digitizer is responding fine then make sure there is nothing pushing against the LCD (anything between the LCD and digitizer) and the connections are seated correctly.

Thanks for the replies. I cant find the rubber seperator thing could that be the problem? I looked at the LCD and nothing is in between it and the digitizer but it appears to be loose. All connections are seated correctly.
If the LCD was being pushed from the backside thats metal would that be a problem?

If the LCD is being pushed it shouldn't be a problem. If a piece of metal was touching the digitizer, then you'd have interference which would cause ghost touches and poor accuracy.

Okay so I took it apart and reassembled it like 5 times and I'm getting frustrated.
Basically the issue is the screen is all wonky after I power it up. The picture was perfect with the old digitizer that was cracked and had water damage, how is this possible? But when I plug everything in I get the wonky picture.
So is it my LCD or the digitizer?
By the way all touch functionality works 100% so whats the deal... because the LCD was working before with the broken digitizer that had no touch working lol.
You could try to unplug the digitizer and see if the picture becomes normal. If so, it is the digitizer.

That glass you ordered is a touch screen (digitizer) itself. You broke LCD. Turn the phone on (obviously you can do it without TS) and see the damage for yourself. But most probably LCD now needs to be replaced as well.
btw, I think you have overlooked some clips or disassembling points as LCD is generally prone to damage, therefore no force should be used when working around it. It's also possible that for taking out digiter you need one of these (similiarly as for iPhones/iPods)
It also looks like the connecting flexi strip on the bottom right corner is compleatly recked and torn. (3rd pic)
