Sliding Keyboard working loose

Anyone that has the xda2s, are you having problems with the slide down keyboard? Mine has gradually worked loose and seems very unstable. The top part of the device rocks side to side , and sometimes gets stuck when opening and makes nasty cruching noice ---- Its starting to worry me, anyone got any good tips?
Thanks
Mike

Just send it to service, not much else to do.

Ok, since posting this i found a topic about opening the XDA2s up and fiddleing around to tighten it up. Does anyone know how easy this process is? Seems quite scary and am not sure whther i should attempt this....

It's only scary the first time. Once you're not a virgin anymore, you'll feel comfortable doing it over and over again. Just don't turn into a slut .
Some things to consider. Use the correct tools for the job. Once the screws get stripped, your SOL. Oh, don't be such in a hurry to take it apart once you get the screws out. Remember to take pics, or if you are good with memory, remember where everything was originally placed. Especially the screws. Had to slap myself a few times for not remembering the screw placement.

i just had my housing recently replaced coz i dropped and scratched it. the keyboard frame + the backside of the front face is considered under warranty. the repair center diagnosed its looseness as "faulty mechanical".

Execellent, in that case im sending mine back so they can fix it! Better than cocking things up my-self!

[Q] screen stopped responding - bad digitizer?

For the last day or so the touchscreen on my Tilt 2 will not respond. I thought Sense was hanging due to text messages so I deleted all of them this morning. That didn't help and neither did multiple reboots so I finally did a hard reset. Now I am really hosed since I can't get through the initial setup. Sounds like the digitizer may have bit it?
I am not at home to flash an official ROM right now but I will try that tomorrow. Other than that does anyone have any other ideas? I am paying for the warranty and insurance so I think I can get it swapped if I have to. Are they still sending out Rhodiums or do they have another device to send in its place now?

Okay, I just flashed the latest official ROM downloaded from HTC. Screen still isn't working. :-( Guess it's time to contact Asurion.

my tilt2 is also doing this, it stopped working about a week or two ago, then started working a few hours later. lately it will work sporadically and most the time not how it is supposed to. i have simplicity. i also have the insurance and i think mine is still under warranty, will i need to put the original sense back on it b4 i send it back in? also, on another note, sometimes when i plug it in to charge it the orange light doesn't come on indicating it is charging, i have to hold the power button for a few seconds. it started around the same time, are these issues related.

Possible fix
Ok, so I have learned that these screens are pretty sensitive, especially if you put them in your pocket. You can sometimes revive this by sliding your fingernail into the seam along the outer edges of the screen and running it along the seam as if you were trying to peel the front (digitizer) off of the LCD. It somehow releases the stuck screen or something. Mine has been doing this off and on for a while and I've been able to revive it several times with this method, though it's getting too frequent now and I'm thinking of trying to replace the digitizer all together. I'm afraid to make that leap though.

The reason this "fixes" it is there some dust or dirt between the screen & panel. If enough gets in there, the digitizer gets confused and ignores any presses.
If you completely disassemble the screen and thoroughly clean it, I bet it'll be fine - no need to replace anything. However, this is a very tedious and delicate process, so be extremely careful.

[Resolved] Digitizer Dead-zone...?

So I got this nice (albeit beat-up, but 100% functional) G2 from a friend, and for about 3 weeks it had no problems. I rooted it, put CyanogenMod 7.2 on it, worked fine.
About 3 days ago, it started behaving really weird while I was using it. Interfaces not responding, at times opening things when I didn't have my finger on the screen, usual possessed phone behavior) I did some investigating with the Developer Tools' Pointer Location display, and there's this massive dead-zone on my digitizer! The dead-zone (while holding the phone in landscape) goes from X=255.1 to X=401.1, and covers all the Y-values in that range. if I move my finger slowly enough through the deadzone from one fo the sides of it, it will register as being directly in the center of it. Other times it will show a very light touch on the right side of the zone, activating interface elements and the like.
What happened? Do I have to replace the digitizer? I don't have a warranty on it, seeing as I got it second-hand. Possible fixes, if it's not a serious hardware issue?
I don't have money to spare, so buying things to fix it might take a lot of saving.
EDIT: Got it in the mail finally, replaced it in 45 minutes. I had to use the dorm's heated-air hand-dryer to get it off, and I kinda messed up the glue a bit, but it's working just fine.

If you have to replace the digitizer, I would not worry. I just got done replacing the lcd on my G2, and it works. I bought the lcd (in your case it would be a digitizer) off ebay and my purchased also included the screw drivers and plastic tip thingy to open the phone. For the digitizer you might need to also get double sided tape.
There is a youtube video showing how to take a part and put back the phone. I think the video was like 30min, but when I did it, the time was 1.5hrs totally.
good luck if you go that route.

Previous post is spot on, for most people I would assume this won't be a hard task, I have opened and repaired dozens of g2s (and many other phones) and although sliders tend to be the most complicated its really straight forward
Find a YouTube video or other instructions online and look at it ahead of time to see if its something you feel comfortable with. Then if so, order the digitizer (90% this is the cause 10% the main flex) for around 15-20$ and all you need is a #0 Philips and a t5 torx and a hairdryer/heat gun
You won't need tape as there is more than enough sticky left after prying of the digitizer. Expect about that hour in half if your new to this, but can be done in less than 20 if you do it a lot Here is a link to info on your phone including repair guides

Best of luck!

Aw. Was hoping this wouldn't be the solution.
That sucks. Just went and ordered one, it came with screwdrivers and the prying tool, but I don't have any double-sided tape. Let's hope it's still sticky. Well, it supposedly gets here on the 9th, so I'll read up on replacing from these links. Thanks for the support. Hope I don't break the thing. :/

[Q] Replaced broken screen, thin line on screen unresponsive

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 don't know about the mechanics of the touchscreen, so all of this is helping me
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.

Cracked screen

Hello!
Today dropped my phone and screen got covered in spider web. The display itself looks fine, but its covered it spiderweb. The touchscreen doesnt respond at all.
What do i need to do now? I looked at local repair shops, they ask atleast 100 euros. But on ebay i can find lcd display+screen digitizer for 55 euros shipped, or screen digitizer starting from 10 dollars!
Can i buy only screen digitizer (as i understand that top layer of glass thats cracked is screen digitizer?) and replace it? Or changing LCD display along with screen digitizer is a must?

So this should fit..right? And are all 3 models LS970, E975 and e973 really same size? Cuz i`ve read people have got smaller screens than original from some sellers on amazon.

Replacing a digitizer is pretty hard and time consuming, that's why people usually replace the whole lcd+digitizer+glass assembly. You will also need adhesive and a heater/appropriate tools. It can be a great learning experience if you don't mind potentially busting your phone. There are no shortage of instructionnal videos on youtube on the subject.
Also, a new G2 is only 190$US .... Just saying ...

As i have two other phones. The g2 mini with Tegra and a razrHD. I'll give a try, thanks for the tip.

Well, i ended up ordering that LCD+Digitzer from ebay. Everything was fine for 2 months, now i have quite large spot that doesnt respond to touches. (See attachment) i already tried disconecting the lcd and digitizer..still same. Is it worth trying to flash another rom? I already flashed stock kdz (had stock before too..)
This happened just today, right after ghost touches went crazy and rondomly oppening everything.
EDIT: That spot is changing sizes..form remains, but it got a bit smaller now. Its truly weird. I put the phone outside for few minutes (its +9C outside) and touchscreen works fine now! What is going on?
EDIT 2: After few minutes of usage, the spot is coming back

I had dropped my LG (more than a couple of times) on its face and it seemed to suffer stroke-like symptoms: one side of the screen was completely dead to touch, and the rest of the screen would occasionally act as though I was touching everywhere which opened programs and messed with the keyboard. I was stubborn and just lived with it and over time, it stopped trying open programs and whatnot. Recently, dropped it again, this time it was a bit more serious. Still no visible damage to the screen, but the "dead spot" moved to the centre of the screen, and again, occasionally tries to open programs and add words to my messages.
At first I thought it all could be related to a software issue. Unfortunately, after installing new ROMS, it never fixed the problem. I bought a digitaliser screen from Ebay as well. I'm waiting on the adhesive tape still so I can't say if this will fix anything. I kind of have a suspicion that its a loose connector (the top middle part of the screen gets super hot only after a couple of minutes of being left on).
I'm just wondering if you have tried taking it apart again to recheck the wiring? I think we may have similar problems (your situation is the first I've come by on the internet that is anywhere close to what's happening to my screen). Thanks so much!
