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.....

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...

Protecting Nexus One from dust (and maybe other known issues)

Looks like a lot of people have been getting dust under the screens of their units, and getting them replaced/fixed/whatever is such a hassle (most especially for those outside countries where N1 is sold).
Let's discuss here how to protect our Nexus Ones from dust and maybe other issues like preventing clicking noise. What hardware workarounds can we do to solve those issues? Can we use adhesives, certain skins, certain screen protectors, etc?
I haven't received my unit yet so I can't share my experience. Can you post pictures of where the dust probably enter and what portions click or whatever problem so we can visualize?
For those who don't have dust in their units yet, we can use the recommendations here so we can prevent the problem and not need to go through the replacement/repair/whatever.
Edit:
Just an early reminder. Let's keep this on topic. This thread is for prevention of the problem. If you want to talk about the cure of it or customer service of Google/HTC/whoever, there's a thread for that forum.xda-developers.com/showthread.php?t=613115

well to use any adhesives you need to open up the phone. This obviously voids your warranty and considering the photos from ifixit, it seems it is pretty hard to disassemble and reassemble correctly.
Skins probably would not work because they would have to cover the small gap around the screen, which would mean the skin would have to cover part of the screen, and that would look stupid.
generally people are reccomending when you get your phone to press down on all four corners of the screen with moderate pressure and listen carefully for any clicking noise. If you hear it you should take a hair dryer and heat up the corners of the screen from ~5 inches away for about 30 seconds and then press down on them to help the adhesive bond and close the gaps around the screen.

Thanks a lot. Rereading the thread now. I found forum.xda-developers.com/showpost.php?p=5362535&postcount=52

My second attempt to re-seal it seems to be working so far...
I took the battery out, put my desk lamp close to the screen corner. let it heat for a little bit. then used a plastic wood clamp wrapped in a towel (so the screen isnt damaged) to compress the screen down onto the heated adhesive.
So far I'm not seeing any new dust and the screen has stopped clicking.
Sounds risky, I don't recommend it. But I was just getting too annoyed. Hopefully it says!

That doesn't cover the cracks though, right?

Yes it doesn't cover the crack, and Dust, lint and "Water" could get in.

I keep my phone completely uncased and haven't had a hint of dust. If your phone suffers from this issue, I suggest negotiating a resolution with HTC (be it replacement, repair, or what-have-you).

Agreed, it's similair to fixing a dodgy electric window in a new car....... er no, the manufacturer can do it, and more importantly where are their quality department??

followed the steps indicated with the hairdryer. unfortunately, during the blow another dust piece got inside...
anyway, i had them both bottom corners clicking. after the hairdryer procedure, both are "fixed" - no more clicking.
i hope that i won't get any more dust pieces under the screen - have 2 of them atm...anyway, it's not that bad.
returning to HTC would not work here, since I am far away from where it is possible, and of course it's all rooted and stuff...
thanx for the ideea!

how abt wrapping with aluminium foil on the areas to be heated with hairdryer?

it seems the bezel has a poor paint layer

well that is what I was afraid of when I bought the note, the paint job of the bezel disappointed me, especially at the headphone plug, it seems that the paint job is really poor, i ended noticing that the paint started to flicker, what a disappointment i hope that it will not get bigger.
I almost knew from the start that it would flake easily especially at weak points like plug in areas, i wish to know how to fix it, but i saw some video and taking it appart is hell, maybe i should consider giving it a brushed look bezel

I've had my Note for around 3 months.
2 weeks back I was sick, having fever, throat & ear infection.
I took a visit to the hospital and unfortunately dropped the phone whilst sitting down.
I was so sick & weak the phone slipped whilst in my hand.
Thankfully the damage was minimal. The only minor mark was on the upper left hand corner of the bezel, a slight discolouration.
I too would like to change my bezel.
Would you be kind enough to post a link to a video which shows how to dismantle the bezel & then put back?
Thanks.

Yes.dont use hard case.if u have to put case on it use them rubber cases.

are you sure that its easy to replace the bezel, are there no wires or stuff to take apart when changing the bezel. So its only removing the 9 screws.

My first Note went for a swim with me in salt water so naturally I tried a few things to get it working again, including removing as many components as possible. The bezel is part of the back cover that the battery sits snug against on all edges, and if you use both thumbnails to separate the screen from this bezel/backplate then it should come off after a bit of manipulation.
IMO it's not worth replacing as one mistake will cause another mark and you'll never be satisfied with it unless it's as new. I've found that only after you get a few nicks and bumps that you actually use it like it's meant to be - used. It's not being careless but spending more time using it than being super cautious is where it's at.

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.

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...

But now you have a guide to use to take it apart.

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.

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.
