Wacked out Touchscreen...

Well, my touch screen has pretty much gone crazy. It keeps picking up a touch in the bottom right hand corner repeatedly, even though nothing is touching it. So it is at the point where the phone just keeps vibrating and spazzing out on the table. I've done a hard reset already, so i believe the problem is likely hardware related, any possible ideas to fix this? I did rub the phone with some tooth paste earlier though.

rub the phone down with toothpaste? hoping for some minty fresh conversations?? only thing that would help with would be fixing minor scratches in the surface and even then it would have to be an older style toothpaste (none of the new gel types) as it would need to be a minor abrasion type
Sounds if the screen is picking up a ghost touch - then your digitizer is coming apart (sometimes can also be detected by seeing an "oily" something under the screen) and the only fix is to replace the screen
You can find some on EBay as well as the kits to do the operation as well
and the directions can be found around here and over at PPCGeeks just search "replacing the screen" or "replacing the digitizer" and you should get some threads with a PDF attached and where to find it all

Yes, actually there looks like a giant blob of liquid underneath the screen, but it moves around so it is actually liquid... I bought this phone second hand, so i assume its probably been through the washer. Water damage stick is red too. However, after leaving the battery out overnight, the ghost touches went away.

surprised it works had it been dipped in a washer LOL
the fact it could still be a digitizer issue as it "looks" as if an oily or water bubble under the screen is moving about when pressure is applied
Best bet, get a bag of rice or a handful of those desiccant packages from a local shoe or electronic store near you, remove the battery and back cover and SD card - put rest of phone in a baggy with some rice and the desiccant packs, close up the baggy and walk away for 24 hours or so
If it is water it will be gone definitely then, if it is the digitizer separating, you will still have the blob under the screen as it is the result of the polarized screens moving to and away from each other causing the look of a rainbow weird oily blob
Once you know which it is, you can decide how to go from there -deal with water (which should be gone after the baggy treatment) or replace the digitizer from EBay

My HD2 got wet, dried out, turns on, has some issues now.

I had it less than a week. I have NEVER gotten a phone wet in my life (45 years old.) and I had this one for less than a week and my dog rammed into me (Big dog.) while I was standing near the sink, texting, and bloop, it goes into the soapy water. I got it out with moments and popped the battery out.
I must mention that when I pulled it out of the water it was vibrating constantly and the LED's on the back were blinking quickly.
It was soapy water with dirty dish crap in it. I got on line and read immediately. I followed the directions to a T. Soaked it in distilled water for about an hour and then let it dry by the exhaust port on the back of my computer.
48+ hours passed and I attempted to turn it on. Insert the battery, nothing bad happened. Press the power button, after a second or two it vibrated and the screen lit up with the logo and my heart was happy. It booted into Windows and I was very relieved.
It was short lived. There are some issues.
There is obviously moisture trapped under the screen. There are dark spots, light spots, swirls, etc. You can't see it too much in Manila but when the screen turns a solid, lighter color (Like in Task Manager or Opera Favorites for example.) you can see the swirls.
People can hear me clearly when I speak but I can barely, oh so barely, hear them talking to me. The volume in the ear speaker is very muted.
The rear speaker, for music, nav directions, speaker phone, etc. is nothing but crackles. I mean you can hear and deduce what's coming out but it's buzzy and crackly the whole time. Just awful sounding.
The touch screen has some diminished sensitivity, maybe 10% less reactive all over and up to 75% less reactive near the edges.
It's so bad that I'm using some piece of crap back-up flip phone from eons gone by. I pray nobody calls me in public so I don't have to pull this piece of crap out. It's that bad. It's magenta too. (That's the manliest word I can think of for pink.)
In your opinion, do you think my HD2 will improve over time? Another full day has passed, back in front of the heating vent. The screen has changed some. I can't say that it really got better but it has changed. Some of the solid water lines that were there are now muddled. Perhaps a 5% improvement. The speakers show no sign of improving nor has the screen sensitivity, they are the same crap as yesterday.
The speakers are really the deal killer, if I can't hear people then it really isn't a phone.
Everything else on it seems to work fine. GPS, Wifi, data, etc.
Should I give up on it, dump it for cheap, and move on to something else like the Nexus One maybe, or wait until T-Mobile US gets their HD2s? (Is there a release date for the HD2 in USA yet?)
What is your opinion, hopefully based on experience on this?
I lost my job last week (Business closed.) and honestly, I'm more sad about this phone than I am losing my job. I know that's twisted but I loved using this phone. Loved everything about it. I miss it dearly, even though I know it's just a phone.
Please advise. Thank you for reading.

Of course the half a second it was in the soapy water wasn't enough to get all the parts really soaked and the water didn't get a chance to get in all the parts and between the lcd and the touch screen so you decided to put it in water again for about an hour just to make sure.
I'd hate to see you rescue a drowning person.
Anyway I'm sorry for your loss.. maybe you can get a friend's insurance cover it.. (figuring your dog has none). Also dry it some more..

Well it was longer than a half second. It slipped under some dishes and I fumbled awkwardly a little bit trying to get it. I would say total submerge time was probably 6-7 seconds. It looked very wet to me. When I popped the battery there was definitely soapy, dirty dishwater coming coming out of the insides. Maybe I did more damage by soaking it in distilled water but it was overwhelmingly recommended on the internet when I searched for wet phone.
Edit: I'm in the US and this phone was not released here. Is there a way to have insurance on a phone not purchased through typical channels?
Thanks for your thoughts.

Bit of a long shot, but have you tried recalibrating the touch screen? Don't think it'll make a huge difference but... never know.
Regarding the speakers, you are probably SOL. I think you'd be surprised what you can sell a busted phone for on ebay.
Re: Insurance, did you purchase it with an AMEX or a 'premium' Visa/Mastercard? You automatically get some coverage.
This actually makes me very nervous because it reminds me that personal digital (the aussie dealer for the T9193) didn't accept AMEX, so I used my normal Visa... sigh. Off to buy a warranty.

That's a good idea, I'll give that recalibration a shot.
Are the speakers made of paper? Did they get wet and become permanently damaged? I've since read dozens and dozens of stories on the net about wet cell phones and I've heard nobody mention anything about permanent damage to the speakers. Does the HD2 have some kind of unique sound system which might make it more susceptible to water damage?
No on credit card, purchased with cash on Craig's List.
Thank you for your help.

Hmm, maybe it's in my head but recalibrating it does seem to make the touch reaction a little better. Seems to run a little smoother.
Honestly, if I can get the dang sound to work half way decently I will be able to live with it for a while. I blew some compressed air (Not high pressure but a decent blast.) into the grills but no difference on either. I can't imagine what's in there, other than a torn speaker, which could make the cones not move efficiently. Maybe some kind of corrosion in the magnetic motor behind the cone possibly.

remember when you search for solutions online to check the date when it was posted.. that distilled water trick maybe worked for nokia 3310's.
Also be carefull with air when it's wet.. if it is paper, I don't know.. but imagin what happens to it if it is and it's still wet.... I'd carefully use a hair dryer... and leave it dry for a week, not 48 hours..
I've seen a Dutch insurance company that insures your phone online without questions.. you just pay a fee for stepping in (€25). There must be something like that in the states. I don't know if you have home insurance, but some companies nowadays also cover mobile phones and laptops, even when your on the move.

You may want to query one of the parts replacement sites to see if they can get you a speaker. Something like truesupplier.com or cnn.cn (Just as a reference, I'm not vouching for the legitimacy of these sites.)

the non capacitive touch screens are indestructable compared to the HD2's.. anyway.. I would have tried without first..
I know my comment didn't help much after the damage was done but it just seemed like the last thing I would do.. that's all. what's done is done. Let's just see if you're insured..!

I've had my fair share of wets phones and I don't think 48 hours is long enough for it to dry out completely.
Cover the phone in a cloth and sit it on top of your television for a week.
Don't forget, you let the phone sit in distilled water for an hour, that's plenty of time for water to soak deep down into the nooks and crannys.

That's pretty much what I'm doing now. Only difference is that it's sitting behind the exhaust vent on my computer which seems to be a nice temperature for drying without being too hot. My TV is a plasma and has no flat surface on top.

HARD RESET <<<< & don't use your phone with battery cover for few days so water evaporate

at this point i would be wondering if soaking it in ethanol / alchohol would do it some good. my reasoning:
-Alchohol / ethanol / similar is a water dispersant and evaporates very quickly
- the liquid is much thinner than water so will get into every nook and cranny
- its wort a go since it seems like its a bit buggered anyway

From what I've read the 99% denatured alcohol rescue is split between two camps, both far on one side of the option or the other.
I guess getting it under the screen might help but I can't see what it could do for the speakers.
If I do this, and I'm very hesitant to do it, it will be a total last ditch effort when I've given up all other hope.
I think some long term drying is in order, and maybe a couple of fingers crossed.

Do you happen to have a product name you can recommend?

cover it with newspaper, then go get uncook rice, cover the phone & newspaper with rice, leave it for a week for completely dry.
Or have a lot of dry silicagel, you can use it as well. If what you have is those type usually found in dry food, make sure it dry otherwise it won't observe water. If it brand new like those found in glossary store, then just put phone in big zip lock bag with the silicagel (or something where air cannot go in or out).
Just remember, don't heat it (like hair dryer, hot air, etc) as that will speed up the oxidize and have rust on small parts in your phone.

OK. How fragile is the screen, really?

Hello everyone.
I got my HD2 a couple of weeks ago and as usual with new toys, am still taking some extra care with it. I had a Touch HD before that withstood quite a few bumps and two small drops. I saw people carying iPhones in pants pockets, back and front. Given that HD2 screen is significantly larger, how fragile is it, really? I usually carry my phones in jacket pocket, screen towards the body, without any case or sleeve. Do I need to take so much care for it or is it actually more resilient than it seems? Yes, I've seen the threads with broken screens. Anything can break, given enough force.
Any serious feedback is welcomed. Thanks.
Cheers, R

Well I have had mine since it was released in the UK and have had it in my right hand side front pocket in my jeans/trousers etc, sat on floors etc and all sorts and nothing has ever happened to it at all. Its a pretty tough screen I think, as long as when its in you pocket its not at an odd angle, I cant see any problems keeping it in there. I certainly have no problems.

Scratch test
There is a YouTube video of a scratch test of the screen of an HD2, its in foreign but gives a good idea of its screen tolerances (those of a nervous disposition may wish to look away towards the end)
http://www.youtube.com/watch?v=NcEaehKWr2s

Hmm I can only speak for myself and my HD2... but my screen has 2 (really small) scratches..
I think these are from a keychain or maybe a lighter in my pocket. I don't really know where the came from - but not from dropping it.
I would recommend to use a (thin - not that thick vikuti) foil to protect it against scratches.
--> Question: What would you recomment regarding a foil to cover the screen? I bought 1 Vikuti foil and really disliked it - it is sooo thick
Edit: I think the knife in the video would be able to scratch the screen... only a matter of right angle an pressure

I dropped mine on new years eve - drunk and the only thing i noticed the following day was that i had lost the backplate lol
Someone on here very kindly gave me a replacement.
Other than that - no scratches so far

Had mine three weeks, using front trouser pocket though I am very conscious of checking the pocket for keys etc first.
I have a full body invisibleSHIELD skin, and i'm extremely happy with it.
I've knocked it a few times on the edge of tables and chairs, once on the metal hand grip on a bus seat, and theres not a mark on it anywhere.

I have a screen protector that covers the entire screen, and carry the phone in my pants pocket in the leather case that came with the phone (I'm waiting on a holster from eBay).
The screen is in perfect condition, however, I did scuff the corner of the HD2 by dropping it (in its leather case) as I went to put it in my pocket coming out of a movie theatre...dropped onto cement.
: /

I use a screen protector and have a very nice silicone case for it that fits very snug, but I'm just being careful.
I believe that common sense is enough to keep this device from being damaged. As you can see from the linked video above, the screen is very resiliant, but it's not scratchproof. Also, why on earth anyone would put it in the back pocket of their trousers and sit down is totally beyone me, but people have done it (and probably still do), but they end up on here asking how to fix their damaged screen. (My advice to them is to hook up a flex capacitor to their car, drive at 88mph, go back in time to before they broke it and slap themselves round the face and say "STOP BEING SILLY!!!")
It's tough, but not unbreakable. Just treat it with respect, look after it sensibly, and DO NOT PUT IT IN YOUR BACK TROUSER POCKET OR FRONT SHIRT POCKET!!!
As the meerkats say... simples
(I hate those adverts, but I do like Back To The Future )

Yes, and even moreso if you have a hernia! Good to see that xda is also responsible for good health advice too

I can't wait for mine to arrive next week. I can tell you from experience that the IPHONE has cracked 3 times in pocket when I put too much pressure. Apple does replace them on a regular basis. They allow for what they call a hairline. If it spiders they won't replace it but a hairline is within their tolerance and is common enough for them to replace it without question. That is how I ended up with a new replacement recently. I wasn't using the phone much but my HD battery died on site so I put the time into the IPHONE to use it. I squatted with the IPHONE in backpocket and CRACK. I probably should check my beltline while I am at it..
They replaced it and that worked out anyways as I am going to sell it. Keep my HD and Bold as backup.
The glass looks pretty solid and as many people reported it a good solid piece of hardware.

i keep mine in the case it comes with when i am carrying it around... any pocket really.
i just make sure i dont sit on it! lol
the screen itself is extremely resilient when it is out and in use.
I leave mine lying around all of the time out of the case and it still looks brand new.
I dont use any screen protector.

screen strength
being a kapasitive screen it uses a propper glass cover instead of ****ty plexi glass or resistive glass as most phones use, this naturally gives it a more scratch proof serface but makes it less resilient to actually breaking. like one guy said it all has to do with angle and preshure.. and abit of bad luck when it comes to screen protection i recomend invisiShield. they are nice and thin, VERY clear plastic so it doesnt disturb teh screen quality. and last but not least, the fabric its made of is teh same as teh stuff that they use to cover helicopter rotor blades with, so it comes with a 30 year waranty.

Thanks for all the replies so far. I suspected as much, but it sure is nice to hear other people's experience

Water under screen in HD2 (update and question)

So I posted about a week ago about my hd2 getting water in it and drying it out with silica gel. It's been a week and the water has dried out about 95% and looks pretty good. I do have a question though (if anybody has any ideas or insights, that would be awesome)...
The screen is looking good but when I load Opera or YouTube (any screen really that is mostly white) I can see light brown striations in the bottom right corner. Could this be water residue? The "water" was actually solution from Invisible Shield so there are probably other things in the solution besides water. Is it some sort of dried out residue that is causing the striations, or is my screen just partially damaged/discolored?
I read that soaking the phone in alcohol will clear out water/residue from water and was wondering if it will work? Anybody who has done it before? Does anybody know if it will "wash out" the residue causing the striations? Thanks in advance. I'd really appreciate any insight!

I dropped my Kaiser in the bathtub (thanks to my overzealous 2yo tossing it at me when it rang) and immediately pulled the battery. I let it sit out overnight in a bed of rice, but the keyboard still had some moisture in it the next day.
I have some dielectric fluid for various projects and decided to give that a shot, since water will float to the surface of any mineral oil-based fluid. It sat there for about an hour.
When I finally got the nerve to turn it on, the screen was very dark and didn't make it past the first bootscreen. I pulled out the keyboard to find that the fluid had stripped the adhesive from the keyboard lining. Now the phone is another toy for my child
Just Curious: How did the fluid get inside the phone? Did you not follow Zagg's directions?

there was fluid on the counter and I didn't realize it. It seeped in from the back where there were gaps. I used to have an iPhone and that never happened cuz there were no gaps for water to get in especially in such little amounts. I've put 3 zaggs on 3 different iDevices in the exact same manner and they never got water inside.

hello people.
i'm a little late for an answer but the same happened to me just today. i removed the first protector and installed the second one and the glass cleaner (i didnt use water, just a glass cleaner that is self drying) got under the screen. i see a big shade that is getting bigger by the hour and i dont know why. i see it very clearly when the screen is showing something white. I' m hopping for now that it will go away.
Also i would like to say that there are some spray canister for that job. to remove the moister from electronic devices. the local dealer of nch corporation demonstrated me once a product like that and i was very sattisfied. So if the moister persist i will try that.

The problem with LCD screens is all the layers of material inside them, once you get moisture, residue, dirt inside an LCD its likely wrecked forever. I mean the LCD will still work but you'll probably never get the discolorations to go away. I have pulled apart a few backlit LCDs myself. Typically you have the LCD panel on top, 2 light diffusing layers, a "lightpipe" that takes the light from LEDs or CCFL tube at the edge of the screen and evenly distributes, and then a silver or white layer backing the whole thing.
Your only true chance to restore the LCD to original, would be to completely disassemble it, separating all the layers and then cleaning each layer back and front with a good cleaner, lint free microfiber cloth, and then try to reassemble the whole thing without getting fingerprints and dust from the air inside. It can be done. but its really not worth it when you can just pickup a LCD module off ebay.

Strange damage on the screen

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.

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...

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.

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.
