I dont know why it is with these newer model phones, but just from the suggestion posts that came up when i entered the title of this thread, but My LGOT and i guess even the G2 have an issue where dusts starts to build up under the sceen....
Ive only had my phone for a little over 2 weeks, but even after the first couple days, i noticed that there were already a few trickles of dirt right around the middle of my screen.
I guess my main question is, is there anything i can do about this, has anyone had the same troubles, and what can we do to prevent this from happening?
In Thailand this is general problem of LG Optimus One
you should contact LG Customer support
they'll open your phone and blow dust out
if dust cause touchscreen malfunction they'll change new one for you
some people guess that dust already in the phone due to assembly process from factory
some guess maybe dust go through usb port
I have my phone since 2 days and i already have a dust spot in the lower right corner. This is annoying! If this spot is growing i will contact the costumer support.

I am working on dusty area, but no dust under screen. Phone is 1 month old.
Me I have not this problem, but remains me the same issue with the iPhone 2/3 (google iphone dust screen).
I think it's a common problem with capacitive screen, but no "easy" solutions to fix it...
poor construction quality, imho.

this is one of those instances where a really cheap phone shows its faults. the phone is free on contract and little of $200 without. with it being so incredibly cheap, there is going to be something wrong that causes concern.
Im okay with it happening as long as it gets fixed and the problem is acknowledged by both LG and the phone carriers. it seems like many people are having this problem at the moment and T-Mobile is willing to exchange it in store, so good on them for being considerate.
i have the same issue. Don't know how to prevent that

Same Here! Very annoying because the phone is less than one week old!
I actually have not this problem my device is now over 2 weeks old. Maybe it depends on the area you are or temp.? ect...

No dust here either. I have a silicon case, I don't think it helps very much.
just disassemble it. There is no warranty seal. You'll find the dust inbetween the lcd screen and the capacitive overlay.

Hi! please tell us how to do it!
I too have this problem Can any one please let us know how to get rid of it.
I have the same problem with my Optimus One, dust is starting to gather on the right bottom corner and it seems to have increased since the first time I saw it. I've thought about buying a can of compressed air and trying to blow it near the edge of the screen but maybe that will just make it spread even further.
I've also thought about unscrewing the screws on the back panel of the phone and clean it but I'm afraid that it will affect the capacitive screen in some way making it less responsive and that after I assemble it back together it'll become even less air tight and thus accumulate even more dust.
Maybe I'll reclaim my warranty but I'll have to un-root my phone and wipe it clean before leaving it at the store and it's going to be a pain in the ass to reinstall everything when it returns.
Will they replace the mobile for this problem?
You can back up everything by titanium backup and copy the titanium backup folder from sd to your pc or pen drive. In your newly replaced phone you can copy back this folder to sd card and after installing titanium backup application you can restore everything.

Wow, DUST really get into the phone and I thought I was the only person experiencing this... actually it's on the "RIGHT BOTTOM PART" as posted S3nd41 and probably half of the users here has this problem....
Hi I am mostly satisfied with my G2 so far, but have two concerns:
- The display is flickering. It is especially noticeable in applications with large white areas, such as Remember The Milk.
- The back cover sits on really hard. I broke my nail in two places when trying to open it, and my attempt with a screwdriver had to stop because it seemed to be able to crack the cover...
Is my unit a faulty one, or is this usual?

Are you using the slot in the back cover to open it .

I had the same issue with the flickering screen, was so annoying especially on low brightness. I had a thread about it as well.
I thought maybe I can live with it but I couldn't so went to o2 and replaced it.
Go and exchange it!
Sent from my GT-I9100 using Tapatalk
Thanks for your input. Was your device faulty, and did the new one work better?
Well yea o2 swapped it for a new one and this one doesn't flicker at all so the previous one must have had a defect some sort of.

So, I've been spending the better part of an hour scouring over the Anandtech teardown gallery of the prime trying to get a decent understanding of the GPS/WiFi antennas and the underlying design flaws which contribute to these features messing up; namely the giant metal shield of a cover and the placement of the antennas. They're not exactly in a bad place, but I guess Asus assumed that if you were using WiFi/GPS with your tablet then you would always do so with the screen facing the AP/satellites. In reality, mine at least, it's the back of the device generally pointing to these things. Maybe I place my network hubs in strange places and enjoy astronomy apps too much?
Now on to the actual question, especially to any of you who have gotten the device and been brave enough to peek inside it yourself; would creating my own plastic windows/metal grates within the aluminum backing actually help anything? Do these antennas broadcast a 360 degree signal or are they directional? The motherboard itself would allow decent signal to get to the transmitter wouldn't it, so long as the case does?
My order isn't set to ship for another month, but I think I'll be getting this tablet regardless of the known issues, though the audio/video problems with the miniHDMI port make me a bit nervous. This thing will still be a power-house even as better spec'd tablets come out, just like my single-core Desire Z is still pretty relevant and decent. Just not top-of-the-line, and it wasn't for any real amount of time, but that's just how these things go.
Ideally, the antenna would couple to the whole backplate, making a big slot antenna (but then it starts to risk being too directional). It's just as probably that the issue is noise or feeble pogo-pin connectors.
If you do make a cut-out, it needs to be about 1 wavelength larger than the outline of the antenna (and you risk de-tuning the antenna if it was designed to operate in close proximity to a groundplane)

Coupling to the backplate, though increasing power decreases accuracy doesn't it?
I hadn't thought of the pogo-pins as a possible culprit, that's certainly possible.
Couldn't I make a couple windows and retro-fit either some plastic or plexi-glass into the design? Would that help keep from de-tuning, especially if kept to a small size with accurate positioning?
Thank you for the response, I know nothing of the finer details on GPS and other wireless signals.
*Edit: After re-reading and thinking, I actually understand what you're saying. Plastic or no, any cutout would need to be a very specific size larger than the antenna itself which would take more than I would be able to do I'm sure. Oh well, I know I'll still love this thing, so long as the miniHDMI works properly, I'll be happy. Phone's GPS works like a dream.
And now I apologize. I found it odd not finding topics on this, but now I've found them and have a bit more of an understanding on the matter. Namely that the cpu seems to have a strong possibility of creating interference for the chip. The casing apparently just worsens the issue.

How sure are we about this? I've read that Apple puts their WiFi antenna behind the black plastic logo on their WiFi-only models for exactly this reason. Not only that, but on the 3g models they simply have all the wireless modules placed on top of the device where they are covered with black plastic as well.
It seems to me that a stupid plastic apple cutout - a complex geometric shape - is not likely capable of being as "tuned" as a rectangular cutout. Yet, I think it's safe to say that the 3G and WiFi versions of the iPad have similar if not identical WiFi performance. That is to say, I don't think manufactures are using the aluminum back for anything other than looking pretty. I think it's safe to hack away at.
Thoughts?

Maybe for some heat dispersion too?
I wish they would start selling the back plate only (like they do with ipods etc)
That way i'm sure someone could cutout a shape and try the antenna behind a plastic window etc, but youd always have the option to put the original back.
I wouldnt mind modding mine after the garantee has ran out.
I think Asus might consider making an after-market backplate that they would fit to your Prime after they have fully tested the issues.

I've been thinking that even if Asus didn't some third party will. And I'm willing to get to cutting the day it arrives if I can determine it'll help. However, I don't want just an open grate for dust and junk to get into. Maybe just a thin fabric filter, or should I close it up with some plastic/plexiglass and epoxy?

I don't see why plastic wouldn't work. It's what the iPad has and it seems to work out in that case.
You should consider cross-posting this in the "General" forum. It is a "question", but the General forum gets a LOT more eyeballs.

i agree, this post should be on general... this would be a great solution, a homemade plastic ipad-like hole... we need it, and if third party doesnt do this, we will have to do it...
well, but anyone tested the device without the case to see the real power of the wifi-gps-bt ?

I will be, but it's still a good two-four weeks before I have mine. All mentions of it I've seen in general never get answered, I haven't seen anyone comment on whether or not they've tried without the backing. Probably because most aren't willing to try and heat up the glue to do so or damage the thing in the process...
Some expertise required
Does the aluminium back plate attenuate both wifi and gps signals? From what I have read it seems to be confirmed that this is the situation, although other factors such as internal interference have NOT been discounted, nor has the connection method (gold pogo pin) between motherboard and the antennae (blackened out pcb strip). I have noted on the TF101 Transformer teardown, a very similar placement of both WIFI and GPS antennae to that on the TF201 Transformer Prime - near the top edge and adjacent each other. Looking at similarities between models, an obvious and perhaps too simple explination would be the aluminium back plate. There does seem to be some interest in experimenting with making some holes (similar to the speaker grill), on the back plate in front of the antennae in the hope that it MAY improve reception. I have read numerous posts and was hoping that someone may have tried this. I don't want to hear about the merits of having or not having a GPS and how it matters to them personaly etc - lets focus people, but whether someone has had the ability and knowledge to try it. I am unsure given the wavelength of both GPS and WIFI (1.2 / 1.5 Ghz) whether mutliple small holes would do it. I feel that a transparent plastic window may be required. I do not believe the back plate is used a coupled ground plate etc. and it is used purely as the chasis. Come on - there has to be some smart engineering graduates/professionals who are willing to give this a go...it would have been nice if they were paid by ASUS but that seems unlikely. Point to note - that the GPS and WIFI antennas (there are two for the WIFI on the TF201) would be obtaining some reception through the front gorilla glass and plastic (on which the antennae are mounted). My question is - what and IF modifications are necessary to the back plate to obtain better reception. Any ideas?
I have not seen a single test where anyone proved it was the back plate. Anyone have a link to a test that shows the prime navigating successfully without the back plate?
I just bought the Nook Tablet brand new at Barnes and Noble. Been playing with it a little and like it but noticed something. On the left side and top left of the silver frame there seems to be a small gap - tiny but noticable. You can push down on it and in the dark you can see the light from the LCD coming out of it. So my question is does anyone else have this? Should I be worried or not? I just got it so I'd hate to have to get a replacememt already. Hoping my luck isnt that bad. Thanks for any answers.
Well the front piece of the casing is definitely put on last and in a way it's looser than the rest of the casing, but mine definitely doesn't have said gap wide enough for light to get through. I'd get the device replaced if I were you - if some dust got in there it could seriously mess things up or scratch the LCD.
I think that's actually the microphone. I also have a small little notch that lets in light, though it's more on the right side. There was a similar question asked on the B&N Community forum IIRC.

Yes, the tiny hole close to the headphone jack is indeed the microphone, but from what he's saying it sounds like there's a gap between the faceplate and the main casing. If that's not the issue, though, then you're absolutely right and he has nothing to worry about.
Here's another consideration though; go into an electronics store that carries Nook Tablets and see if their model is identical to yours; if so, then obviously yours is the same as anyone else's.
The micro is more to the right like the 3.5mm jack not the left as he mention.m so maybe that is not it.

Wrong - as I and Verinoca stated - I said it was on the left side of the device, where the mic is nowhere located. Also I think I'd know the difference between a small hole and a gap
But as Mike has said - I think that's the issue. It seems the silver frame is loose and not properly placed onto the main casing so you see little gaps and the biggest gap you can see the light from the LCD. So I'm worried that it eventually comes off or dust gets in - either which is very bad.
Called the Barnes and Noble store I bought it from and having it checked out. Hopefully I get a new replacement since I just bought the damn thing yesterday :/ but thanks for all the answers and help.

So just replace one as you said or you must use it carefull.
I got some dust particles on the inside of the lens which really annoys me. Due to this the camera does not focus correctly.
I really want to keep the phone waterproof so i am afraid to take it apart to clean it. Anyone experience similar issues or even swapped the backcover? Any recommendations for a backcover that ensures waterproof ability after swapping it?
thanks!

If you're getting dust under the lens you're obviously not water tight. I have ordered a replacement back and it cracked just picking it up. I don't know how fragile the original is but I'd be very careful while removing it. New seals can be bought for a few bucks.
not sure where this came from - the body is 100% waterproof...maybe "dust" particle is not the correct explanation
maybe is scratch dots from keys in you pocket?
it abit look like dust...
i mixed my pockets by mistake and left few dots maybe u did it lots of times.. ( i know the lens is plastic and not scratch resistance ) so i try to avoid keys in the same pocket

the scratches on the outside of the lens are no problem since the sony coated this and also polishing is working quite well. also i checked this several times with a magnifier.
i have uploaded a picture of the particle that causes the faulty autofocus. at the picture on the right you can see that this is on the inside of the lens.
since the phone is waterproof this is quite clearly a production fault but since i need the phone for my everyday work and life issuing a rma at sony is no option for me.
i was just wondering is someone else experienced anything similar or swapped the backcover and tested waterproof
You can test your waterproofness of your phone to do the pressure test in the service menu.
Go to dialer and dial *#*#service#*#*, go to service test and then pressure sensor. The value indicated on the screen should increase by pressing on your screen when the phone is still waterproof.

How much does yours go up? Mine started at 997 millbar and goes up to 1002 millbar max when I started seeing discoloration from pushing the LCD too hard.

that's fine. Mine is also just a few millibar. try it with the simtray flap open. It won't increase a bit.

Hi
I have had the same kind of dust in my XZ5
I sent it back and they have exchanged with a new device.
Manufacturing issue... It could happen
Sent from my HTC 10 using XDA-Developers mobile app
since sony support couldn't offer me an adequate solution for their manufacturing error I decided to find a solution by myself.
primary most important was for me that i do not open the device.
I got rid of the particle by freezing the phone in the freezer for 20min and tapping on the lens. The particle fell off and now somewhere i do not care about )
if someone has a similar issue this might be also an alternative solution
Same problem here. It supprises me the presition in which this product was conceived with programmed obsolescence. Just after guaranty ended I began to notice blurs and dust.
I suppose gaskets became less performant as they get harder and they can't hold pressure changes anymore, like when you take a plane or enter a tunnel in a train.

I have the same translucent gray dust spots on my rear camera, and tapping and bumping with strenght makes them moving around. Of course this is programmed obsolescence.
Moreover they fill phones with glue and adhesives for "water-proofness" purposes... but after 2 years of daily use, noone sane minded would submerge any phone and if you have the need, you can't easily fix anything inside the phone or change battery if you aren't a technician , because you have to use professional tools to melt glue and move parts.
That's the current world of "water-proof", thin smartphones.
Something must change if we don't want to swim in oceans made of electronic rubbish in the near future.
