Dust under the touch screen - solution!!!

Hi to all who have dust between the touch screen digitizer and LCD.
I send my device 3 times to the authorised HTC service center because of this problem, they cleaned it (not perfectly) and the dust was back again after few days of use. This was really ennoying for me...
After several disassemblies, cleaning, research where dust comes in, then assembles I found the flaw.
The dust doesn’t come in via sealing foam between the touch screen digitizer and LCD.
There is a bump defect of phone housing around the volume keys. Inside of the plastic housing is a metal frame, where the touch screen digitizer is stacked on - that frame is a little bended and the touch screen doesn’t stick properly on it (around the volume keys only). When you look close on the phone you can see also a little wider gap between the touch screen top glass and silver plastic housing edge. (See picture)
WARNING
The following directions WILL VOID
your warranty - you are performing
this repair at your own risk.
So, now, what you have to do:
For those, who have already dust in, just simply disassembly your device (if you are brave enough, have all tools and precise hands - maybe some experience ) and remove PROPERLY all dirt with brush, compressed air and antistatic cloth, then assemble it back or send the device to the service center to clean it (wont void the warranty). Before sealing your TD2 (keep it in plastic bag away from dust) prepare a sharp wooden toothpick, neutral transparent or black silicone (you can purchase it from any building material shop) and cotton cloth.
Now you have to clean the gap between whole plastic silver housing frame and touch screen top glass with soft brush. Then use sharp wooden toothpick to impress the silicone into the gap (all gaps you can see, just in case) (silicone does not damage phone housing and TSCR surface and it’s easy to clean), then just gently and properly wipe off all the rest of silicone from phone surface. (be careful not to get silicone to the keys or phone receiver slot)
Leave the phone for several hours to get silicone dry.
Then you can use your TD2 in dusty environment and your display stays absolutely clean and dusty free. (TESTED on mine, for me perfect phone now and I am very happy with it...)
For those who have a little dust in and want to stop come more in and those who are planning to buy TD2 (dont wanna play the lottery faulty or not ), do the same procedure (silicone impress only) after unwrapping your device from plastic package.
GOOD LUCK!!! ENJOY YOUR ABSOLUTELY DUSTY FREE DEVICE!!!
Sorry for my English

I don't know about you guys, but I'm not crazy enough to void the warranty of my phone because of a minor thing like that. When mine gets dirty, I send it back and that's it.
If it gets dirty again, I send it back again...
But, it's a good tutorial for the "brave ones" anyway Thanks for sharing your experience with us.
HastaSSSS

I sent mine back over a week ago due to this dust problem (in fact I delivered it in person to HTC repair center in Milton Keynes) hoping for a quick turnaround.
I'm still waiting for it to come back and missing it terribly. I'm back to using my old Nokia E71 which is a great phone but I like my new one and want it back so I may go down the route of the OP just so I don't have to repeat the return each time I get a dust issue.....

i dont want to hijack this thread. if i am then i am sorry
but hopefully you can input your expertise into this thread or help form an opinion for a new thread

I just got a topaz and want to keep dust from getting in but I'm confused about the sillicon. Could you describe more clearly what it is and maybe post a picture so I have some idea what it should look like.

from the picture, for the second gap, apply the protective foil that comes with the phone. Should solve a bit the problem. Ber in mind that after apply, the touchscreen will not have the same sensitivity. You'll have to tap a little bit harder ...

i think you meant screen protector no?
anyway thx for the info,
if anyone knows how to disassemble this device pls help

yes, screen protector. Better not use the screwdriver ... remember warranty ...

I thought these dust under the screen issues had been fixed long ago, but now it seems the problem that affected my old c600 has come back to ruin my topaz after just 1 week.
Not impressed.

I already use a screen protector. I'm more concerned about the first gap. I really don't want dust to happen since I bought my phone second hand and it doesn't have a warrenty.

you can always use a can of pressurized air to get the dust out. (same you use with PCs)

Wouldn't you need two holes that are connected if your blowing air into the device? One for the air to go in and one for the dust to go out? I don't have any dust under my screen currently and would like it to remain that way. The silicon method doesn't seem to difficult or dangerous which is why I'm interested in what silicon to use.

from what I understood (from the pictures in the 1st post), it's not actually a hole, but a free space = gap.

I opened the D2 (only the two upper screws - for lifting the inner part a bit) and did have a look for "gaps" somewhere around the volume controls - i did not really see a gap
But for getting out the dust: dont blow air into the D2 but get the air out - i actually used a vacuum-cleaner. If you remove the two screws it is possible to lift the LCD below the volume sliders *A LITTLE BIT* (=about 0,5 mm only!!!!!) with a small screw driver to create a gap. It worked quite well. (be aware of high air flow and possible static electricity)
But i really would like to know, where exactly to apply some supplementary sealing to get rid of the dust-problem. Any detailed pic would be appreciated.

Yeah Me too!

OK, people, just put some neutral silicone between (in the gap) silver plastic frame and touch screen (there is just 0,2 -0,5 mm gap, almost invisible) and you wont get any dust under the touch screen. This is the best solution, you could do it from inside, but its much more complicated...

What exactly is neutral silicone? Do you have a picture of it so I know what to buy?

I'm about to buy the TD2,
is it so big problem this dust under the screen?
Does it happen often?

I've had it for about a week and the user I bought it from had it supposedly for about 3 weeks and so far no dust. I'm still terrified its going to happen though.

Thanks for the pic, pedroo - so they simply should have glued the digitizer surface a bit more careful to the housing...

Strange damage on the screen

I'm using my SGS for almost a month now and there're appearing strange spots on the screen. I have absolutely no idea what it is and what's causing it. Has anyone seen something like this before?

Never before.. the screen is totally off? What do you use to clean the screen? Do you feel the same touching the bright area and the opaque area?

Silly question maybe but has it got a screen protector on it?

Is it very humid where you are? Looks like moisture under the screen.
Take it to Samsung, maybe it's some kind of defect that's allowing moisture in.

There's no screenprotector on it. When it just appeared I couldn't feel the spots, now I can by moving my finger over them. They look like tiny scratches caused by sand but I always carry my phone in my pocket so that's just impossible.
At the photo the screen is totally turned off. I don't use any chemicals to clean the screen.

No idea.. I'm using screen protector until I got it out the box. By the way I always carry it in my pants pocket, and normally I use jeans... but the protector looks fine.

The area does look like the usual place to touch the screen (normal keyboard usage at the bottom of the screen and up/down scrolling in the middle). My only conclusion is either a defect screen or you've used it once without noticing you still had some chemicals on your skin.

My thought too, maybe it had pressure with someting when you had it in your pocket with something else that was in your pocket or something that pressed you leg/poket for outside

I never carry something in the same pocket a where I carry my phone in. As I move my finger over the screen I can slightly feel a bit of rough surface but when I clean my screen it's not visible while some other damaging is.

If it is in fact a damaged screen I wouldn't panic too much. There are tutorials online on how to repair damaged screens (as long as they're glass). You sand and polish the screen and it comes out as good as new. Although, for the SGS it would probably be best to remove the screen from the chasis first (they don't remove the screen as there is no bezel).

What games have you been playing? It look more like rubbing marks on several games that I can think off.
The damage is probably under the glass from excessive pressure over a pride of time.

The coating has come off the screen it looks like... something must have been on your hands that burnt it off.

It's almost impossible the damage has been caused by excessive pressure. Since a few days I can actually feel the spots as they are a bit more rough then the rest of the screen. If the coating has come of the screen, will it be accepted when I return it warranty?

I had exactly this but a bit smaller. I took it back to the store (Hi) and requested a repair. The first time i noted 2 errors for it:
- Screen screwed
- GPS fix doesnt work or takes long
So... what they did; they flashed 2.2 and sent it back as repaired (funny I downgraded it to 2.1 stock after running 2.2.1 for weeks for this repair...). The folks at Hi agreed it was bullsh*t and they sent it again with the notice they didn't repair the screen. After another week the online status page said they didn't find a defect. Hi called them before they sent it back to have another look at it, since I even provided pictures with a red circle around the spots I'm still confused how they could miss this (maybe only blind people work at Teleplan...?). Then a few days later i saw they replaced "front mea i9000". Since today i got it back with a brand new screen. So.. if anyone else has this problem: send it back for repair and provide the picture in this topic to be extra clear (I wish I saw this photo, otherwise I would have provided this one with it).

I have the same thing only a lot smaller...
I have a circle on my screen from my €2 currency. Its not a scratch but something weird...

did not you touch it accidentally with a "dirty" finger? (like isopropyl alcohol or adhesive remover etc) I had a similar damage on my HTC phone long time ago... I forgot to wash my hand before I picked up a call.

Looks like pressure damage. Had something similar with a htc touch. Looked like a oil like fluid within the screen. Amazingly the screen works still great. But the touch had a resistive screen, the sgs ones is capacitive. This in mind I don't know if it could be the same problem.

Smashed screen...

Hello.
The other day i dropped my phone and it just shattered the glass on the screen.
I'm still using it (but getting little shards in my thumbs regularly) but i'm just wondering what i actually need to get to fix it; is it the digitizer or is it the LCD as well (or are they the same thing). I found this:
http://www.ebay.co.uk/itm/NEW-HTC-D...K_Replacement_Parts_Tools&hash=item564688b2a0
Is this all i need? And do you think i would be able to do it myself? I don't have much experience with this sort of thing but i took apart my Macbook pro and the disk drive once. (Not the same scale i know...)
Thanks

Yes, the digitizer is the gorilla glass layer over the screen. It is responsible for the touch functionality in your device. If pictures on your screen are shown correctly and there isn't any dead pixel then your screen is intact and need not be replaced.

In all disassembly videos i see skipped the step where touchscreen is separated from lcd...
this step it's not so simple to do.
you need to melt the glue under under the touchscreen....
in some video is said to put in oven....10 minutes at 60 degree...but i didn't have success with disassembly these two parts

yeah, that step is difficult. I used a swiss knife blade (the small one) and could seperate the digitizer. I didnt put it in the oven or sun. But i guess its easier if u do. Just hold the knife steady parallel to the device.
I used double sided gluestrips to reatatch the digitizer but still the screen shows up a notch at the bottom of the device....seen this on many repaired DHD...so i think its very difficult to get a DHD where you dont see that its screen was replaced....

some part of the screen not function
some part of my touch screen not working. is this due to a dead pixels? if not what wil the cause of it?
Appreciate if you can assit to explain n perhaps some solution & advise.

If you haven't taken it apart there is NO WAY there can be dust "IN" the screen, it's hermetically sealed.
If you have scratches, just replace it, there are numerous guides out there but google is HARD, isn't it.

There is way! Well, maybe not in the screen but I have something somewhere under my glass in the top left corner too. Maybe not as bad as on the picture in this thread but in the right angle and light it's very visible.

Trust me, it isn't. At least not in all of them. The digitiser & screen are separate, not hermetically sealed to each other at all. They're cheap Chinese phones, little manufacturing defects are common. Small gaps that dust can get into are common, the back light leaks out of the side of my blade, I can see a gap, it shines out quite bright in the dark, I think I'm just lucky the gap isn't on the other side of the screen. My last blade (that broke) got a bit of dust under the screen (between the screen & digitiser), so far this one has avoided it.
You need to be careful if you're taking the blade apart, there are some delicate parts. The ribbon cable that connects the digitiser is a bit fragile.

I think there is something different between the GEN3 phones and others on this too.
The digitizer and the screen are fused together by a vaccum seal on my phone, it takes quite a bit to pry them apart and i can promise you that no dust could possibly get in there.
I think you're referring to white spot edge, a common phenomenon on backlit LCD's, it sounds just like it, i use hot glue mixed with water colour to fix that on on second grade items i might buy off the ... market...

Samsung Galaxy S3 I9300 - Extra Screen Replacement Information

My Ex droped her Phone and it had Spider Webs all accross. Her Provider send it in to see what it would cost to fix. The Phone also would stop working correctly in the middle of calls.
It turns out buying a new one would have come cheaper atleast thats what came back as a answear.
So I decided to bite the apple and try replacing the Screen myself. My Ex was not happy because she thought with the second Problem it is not worth the effort to fix the Screen and maybe loose everything. My reasoning was that when the Spider Web Screen touches the Digitizer it will react strangely. So I went ahead and searched the web on how to do it. I ordered a Screen for $9 on ebay (free shipping) which came with a couple of Tools. More on those later.
One of the first Problems I found was that all instructions that I found showed the beginning and the end. But in the middle how the phone will look like when the glass is finaly taken off, I was unable to find much Information about it. Also doing it Redneck style without Special liquids and or a heat guns was no where to be found.
I decided to just try it. Disasembly is well documented and easy enough to do on this device. Atleast to the Point where most electronics are removed so that you can apply heat without too much problems. I decided on using a blow dryer to heat up the Display. I layed the Blow Dryer on the Counter turned it on and Held the phone up to it. Thinking if my fingers get too hot chances are it is too hot for the Display too.. Might be a little incaccurate to read the temperature like that but hey it worked. But soon after I started to remove the first pieces of broken glass I ran into Problems.
As per instructions I found, I put a Piece of tape accros the Screen so that the individuall pieces stayed ogether. That did not work at all for me. It just made the individual pieces push against the valuable digitizer below it. My next Problem was that the Tools that came with the replacement glass, especially the Little plastic Tools did not hold up to the Job und the tip was soon useless. I had to Switch to a Raizor blade. A couple of times I sliped and hit the Digitizer. Thinking oh well I guess I Need to get a new one. Luckely on the end it all worked out much better then I would have hoped. The left over glue I rubbed mostly off with my finger which worked out nicely. To clean it completely from ist glue took some time. The black rubber allong the side of the phone allso suffered. You might want to look out that that does not get riped out completely. I had enough left over so that the glass would sit on it good enough luckely.
Take a look at these Pictures and remember it works perfectly again for $9. While it is not for everyone to seperate a Glass from a Digitizer it is acctualy less fragile as you might think. The third Picture Shows you how it looked with all the scuff marks from taking off the glass. You can still see a few little marks on the end but hard to notice and much better then before. I am sure next time I will be more carefull and use the blade from the beginning on.
I got more Pictures and will improve this Thread for others that have to go through it. Feel free to PM me if you have any Questions. A list of other resources will also be included. This is only to explain and Show the bare state.

You should be able to find a new Frame for a resonable Price. Now to remove the digitizer from the Frame that is another Story. Not sure if it was the Glue or what Held it in place but I could not figure out how to get that out. luckely the two Buttons at the bottom survived the Screen removal and so I did not hat to take the Digitizer out.

Useful information and explains why repair shops will usually only replace the complete assembly. Read many complaints that those cheap ebay screens are plastic and easily scratched, not genuine gorilla glass replacements?

It is definetly cheaper then the original but if you have done it once. Chances are You will be able to do it again much easier. So if the $9 Glass only holds for example a Year. You can just replace it again. Or spend a little more for a original replacement glass.
Now I should Point out if the rubber seal around it gets damaged in the process and if the 3M Tape that should come with the Screen is placed wrong it will Impact the sensitivity of the sreen touches. I guess I did it right because my Ex is happy how it performs and that is saying allot.
