Dark "stains" of "ink" behind screen?

Just wondering if anyone else has had the same problem. Last night I turned on my phone to find what looks like blotches of ink stains or oil behind the screen. Touch screen works just fine and I can see the entire display. It just looks like the lcd is floating just above these "stains" or whatever they are. If I press on the back of the phone at the battery cover, the stains move a little. Very strange, considering I baby my phone, have never dropped it or gotten it wet.
T-Mobile is sending a replacement, but I'd still like to know what happened and if I can fix it.
Thanks.

PLEASE
Please post only one thread in one section. Multiple threads about the same thing are pointless. You will get more help that way. Thanks!

[Q] Is Sensation LED Indicator significantly visible at angles?

This feature will add up to wanting me buy sensation, aside from dust proof, and touch responsiveness issues (hope its software related not grounding stuff):
knowing that LED indicator is behind earpiece grill, can someone describe the visibility:
* looking straight on the phone?
* looking at 45 angle at 2 meter distance from different sides of the phone?

Straight at the phone u can see it, at 45, a half of the flash? Well, it's okay...

It's noticeable to me! That was a feature which is missing on the G2x that drove me crazy every "smartphone" should have a notification light!

Thanks a lot, LED visibility should be no issue now for me.
I will keep an eye on dust entering beneath the screen and swipe not responsive issue..
I wonder if dust already there since phone was bought or dust can enter..?
The latter is worst, it is a screen sealed issue..

There is no dust under my screen. There is no way that dust can enter screen after purchase so those who have dust under screen must of bought a bad phone.

Anyone replace a digitizer on a sensation yet?

Cracked my digitizer and the new one is supposed to be here this afternoon. Anyone done this yet? Anyone found a good breakdown guide?

How did you go? I'm about to tackle it tonight!

Here's a video

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.

How did you go with your theory? I just replaced the screen in mine and I am having issues with my sensitivity when the screen first turns on, too

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.

So do you think it's the digitizer itself?

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.

I'm wondering if it might fetch more, if I put the cracked digitizer back on there.

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. :/

No Screen! Cover Replacement Gone Horribly Wrong! Help/Buy/Suggestions?

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.

A) $75+ for a new screen and attempt to fix myself?
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?

You know how long its been since I read about a Hox issue that hasn't been posted yet???? I feel bad, that sux, it really does, but this was by far the funniest thing I've read about in a while
Sent from my Nexus 7 using Tapatalk 2

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.
and an xda member said he'd sell me his lcd+digi for a good price but its a HTC Branded one instead of AT&T, i think it will work the same tho,

I got the HTC logo digitizer/lcd. Worked fine vs the original att one
Sent from my One X using xda premium

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.

Lol yeah I know what you mean. I ended up putting some black electrical tape over where the light bleeding was on mine (just under the capacitive buttons) before putting the screen in... and it didn't help much, it just looked more weird looking at it from different angles haha. So I just keep the lights off.

eww I do not want to see leakage from the bottom!
Hopefully i get lucky and only have to take apart once and be done with it!

[q] lcd scratched area

hi guys, so i bought a replacement screen, am yet to receive it. It looks very neat, only problem is that its got a scratched area on the top side. My question is, is it possible that scratched area will show when the screen is on? Also how can i hide that scratched area from showing when the phone is on sleep mode i.e when screen is turned off? I have attached a photo of the LCD

Thats a pretty bad scratch... Yes it will show while the screen is on, off.
Put a sticker over it? Sometimes screen protectors will make scratches look a little better..

Did the seller show you that before purchasing? That's a big area, looks like sandpaper was used to clean screen. I would have returned for another screen or a refund.
