[Q] Hot phone bright screen, cold phone dim screen. ???? - General Questions and Answers

I dropped my phone in a puddle of water during a light drinking binge a week ago. I did all the known techniques for drying out. Rice, etc.
Waited a whole week before turning phone back on, everything seems to work great except screen is very dim. I thought maybe it still needed a little more drying so I took a blow dryer to it. Phone was nice and warm. Afterwards turned phone back on and screen was bright and full of color. I thought wow its fine. About 10 minutes later screen went dim again. Imagine my disappointment. I thought what the hell I'll try the blow dryer again and bingo screen bright and full of color, but as soon as phone cools the screen is dim again. The heat from the blow dryer brings my screen back to life everytime but as soon as it cools it becomes a paperweight. :crying:
Just wanted to know if anyone had any explanations as to why this is?

if you have screwdriver set and some skills... watch a video and open your phone... maybe there some moisture left
PS: Its not that difficult if done correctly

Thank you all for the help.

I took the phone completely apart down to the last screw. Laid all the pieces out on a towel and used the blow dryer for about ten minutes. Put everything back together and BINGO! Has worked like a charm ever since. Thanks again.

You are most welcome!! It would be great if you could subsribe to my youtube channel!!

[Q] A "washed" through laundry HTC Diamond

Hello,
by a rediculous accident I forgot my HTC Diamond in the pocket of my jeans when running the laundry :-(
Afterwards, I opened the cover, took out the battery and let the phone dry out for 2 days. Now I've put it back together, and connected it to the charger. The "ring" is flashing, so the battery is charging but the phone itself is not starting and the display remains completely black, not even the vibration kick on starting...
Is there anything I could do? Or perhaps there is a chance to get out some photos I have shot earlier, would also be something...
ive heard that taking apart your phone and leaving the parts in rice can help (because the rice absorbs moisture)
Off topic:
I read one Desire went through a washing sequence in a washing machine in Desire spesific forum and now this?
Is this a new hobby? I mean... washing smartphone

If the photos are on your micro sd card, you may be able to plug that into an adapter and plug it into your PC and gain access to them that way. Just be sure that micro sd card is thoroughly dry before doing so.
WORKING !!!
Hello,
thanks for the replies... This morning the phone booted!!! I was able to download the photos!!! But the screen has stains, obviously the remaining water.
PLEASE advise on how to dry that thing completely !!!
I think that I'm gonna pass on the rice thing.
@aaa - YOU ARE A JUNKA$$ !!! You think that's really funny?!? Especially when I'm currently TIGHT on budget and need the money for other things and the next phone is planned no earlier than Christmas... I'm hesitating whether you're a real human being...
You can dry it completely in an oven for three hours at thirty degrees or so. I've done this three times. If you have a fan forced oven, just turn the fans on, that'll be enough.
A safer way (if you can obtain it) is to leave the phone for 24 hours in a bowl of dessicant silica gel. You'll often get a small packet of silica gel when buying new electronics or other moisture-affected things. That small packet is enough, just put it in an airtight bag and leave it for 24 hours.
The next step would be disassembly and a thorough swabbing with denatured alcohol, but that's pretty extreme and only needed when the device isn't booting.
Some LCDs are hard to get moisture out of, some are not. Leaving the phone with the silica gel for longer will have a better effect. As the previous poster mentioned, rice also works (quite well), but takes longer than silica.
Good luck with it!
Another thin that will absorb moisture is common table salt. Take the phone apart very carefully. Remove battery first, make sure you're grounded as well.
Hello everybody.
thanks a lot for the numerous advices...
Unfortunately, I have more to report...
The phone dried out and booted 2 or 3 days later, as I said. The stains on the display disappeared as by magic one day later.
Everything was fine for a week until I launched the camera 2 days ago. The backlight of the display went off and came back only after removing the batter for 15 minutes.
Now the backlight is going off pretty often, sometimes it requires to remove the battery 1-2 times before it starts working again and yesterday it happened that it got activated again when I got a call...
Any ideas please?
And also the phone keeps overheating from time to time without real load (GPS or wi-fi) which dries out the battery. But I had this problem also before the laundry
Sounds like that moisture in the LCD unit left a bit of residue and is shorting the backlight somewhere.
Only option there would be to disassemble and swab the LCD boards and cables/connectors with denatured alcohol.
Alternatively, a new LCD unit should fix the problem if it persists, just make sure you alcohol swab the connectors before plugging them back in
Someone also mentioned drying out in salt before. While that does work, salt is extremely corrosive on solder and SMCs, so I wouldn't recommend that route.
i heard hair dryers are the bomb at the screen moisture, just take off all that you can and blow dry it.
I just don't understand your refusal on using white rice. It have saved countless phones.
Uncooked white rice is VERY mosture negative. Just put layer of rice, put your phone on it, cover it completely with white rice, seal it in. Ziploc could work too.
In a day or two your partially dry phone will be bone-dry. If it was soaked still you could first try to shake out water as much as can, soak it in distilled water to remove minerals, then white rice it for 3 to 5 days.
I had this problem with my Touch Diamond. Everything worked, but while i was trying to dry it I broke one of the battery "hinges" but the phone still worked after except only with black screen. The best thing to do probably is just leave it for a couple of days and hopefully your phone will be back!

exactly what ive said. ive read everywhere that rice is one of the best solutions out there
Like was said before you most likely have some corrosion on a few contacts, if you have about 6 bucks you can spare you can get residue free contact cleaner in an aerosol at radio shack or any electronics store and save yourself having to scrub each contact and connector. Just tear the phone down down spray all the contacts and connectors with contact cleaner let it sit for a few then spray it down with air duster to get any thats get under the resistors, in the connectors, etc that hasn't dried; let it sit till you're positive everythings dry and put it back together. Does the same thing as alcohol just alot less scrubbing.

Hello,
thanks for narrowing the problem down.
But for me it looks like something different, because:
1) I have been using the phone for 1 week without any problems and it got screwed after I've launched the camera app for the first time
2) The backlight works when I power on the phone. But its stop is event-triggered, like when I launch the sound or video player or when I get a call... Similar events would trigger the backlight back on.
Perhaps reflashing the software could fix that?
I went to a shop today and put another battery. The phone booted, anyway without any backlight, twice...
At least the device is still alive.
There probably was a tiny water bubble and it messed with phone when you turned camera on.

Either that or a short in the cameras circuit from corrosion, either way i'd pull it apart before it gets worse and check it out.

potential long term damage?...

Yesterday my phone got wet, the screen is howing some kind of wet spot under in, but heres the thing?
At the edges it seems the water damage is lightening the screen, yet in the middle theres a dark shadowy patch!
Any advice is great thanks?
take the battery out put the phone at a bowl with a dry rice give it a 48 hours
and your phone will be like new (tried a lot of times)

This. Do this.
And do not delay.
If the phone works at all now it's because you're lucky and the water didn't get to anything sensitive yet. But the key word is 'yet'. It only takes a drop of water on a circuit board to ruin the device. If you don't have any rice at home right now, turn the phone off and pull the battery out NOW. Then go get rice. Don't leave the phone on to go to the store. The sooner the power is off, the better.
What happens is that the board gets slightly wet and when electricity is introduced there's a short. And tiny little circuit boards aren't designed to deal with electrical shorts. It hurts them. Badly. And quickly. And irreparably.
So taking the battery out is key as there's still electrical power in part of the circuits when the power to the phone is off. (Something's got to be polling the power button to know what to do when it's pressed. Something has to regulate the charging that works when the power is off, etc)What the rice does is creates a very dry environment by absorbing moisture.
In 2 days the rice will have sucked the water right out from under the screen.
And once you put it in the rice, don't touch it. Don't test it. Don't fuss with it. Just leave it there for 2 days and use another phone.

DO NOT RUN YOUR PHONE IF IT GETS WET. PULL THE BATTERY RIGHT NOW.
Even if your phone gets wet it is usually only damaged by running it after it is wet. If you let your phone dry for a few days it should be fine.
Thanks for the advice, that much i was already aware of - it was the dark area that appeared on the screen.
I have had the phone back on and run it with the screen max brightness and the dark patch has almost gone theres 2 small dots that are slightly lighter.
I will see what its like tomorrow.

It should go away completely. I got mine where it was dark all the way around,and a fairly large spot in the middle. I just left my phone off four 24 hours, then used it, the spots were still there, but they went completely away.

[Q] Galaxy S4 got wet - almost turned on

I dove into a pool the other night with my GS4 in my pocket, I didn't even realize it until the entire pool lit up with a flash - I guess thats the liquid sensors letting me know or something it was pretty cool though.
I got it out and put it in some rice right away and left it there overnight. I tried it in the morning and it still didn't work so I put it in a bag of rice, it's been in there until today, about a day and a half later, and when I turned it on it brought up the samsung screen with the dead-bolt lock. It stayed there for about 5 seconds and then turned off again.
I decided to take it a part and see if I could see any water damage. I had it taken a part and did see some chlorine residue, so I got a toothbrush and scrubbed all of that off. I scrubbed every connection/terminal.
When I put it back together the blue LED light on the top left came on, then slowly dimmed. It's still lit up, but I can't see it unless i cover it with my hand, and even in that shadow its still very dim.
I don't know if I should let it sit in some rice some more or not. That's my only idea, but I'd love to hear from you guys if you have any ideas/solutions.
Thanks in advance!

Honestly, you've tried the rice trick which is the best bet as it's a natural dessicant. After that, and stripping it down, I think you might just have to accept that you made a really expensive mistake. The only thing maybe worth trying is to get a new battery - you might be really lucky and find that's all you've killed, but it is a seriously long-shot.
Thanks, I'll definitely try the battery, I'll post here if that was the problem.

Water Damaged Phone, Help!

Hey!
So On Saturday I dropped my phone down the toilet by accident, i removed it from the toilet, after about 5-10 seconds, and it was still on, it seemed fine, so I was like ohh okay...i dried it ect ect and it was working fine, but some parts of the touch wasn't working so I left it on as i could not switch it off. On that night i dried it with the hair dryer as well, didn't work, so wrapped it in a towel and but it in the boiler cubard to keep warm for around 12 hours maybe more...tried to switch it on and it didn't work again.
the day later (Sunday) decided to take it apart, and dry the insides, still wasn't working, but the notification light is on and sometimes flickers so i slept with it under my pillow as it would keep warm over night, on Monday, i put the charger in and the screen came on to that battery charging screen for around 5-6 seconds and it said it was on 0%....the notification light was still on.
I Put the phone in some rice in a box, wrapped it in a towel and left it in the boiler cubard again until Wednesday, afternoon....
what can i do?? will this work?? how much would it cost to get fixed?
is the touch screen broke? do i need new battery? ect ect
THANKS!
Best thing to do if you get a phone wet is turn it off and leave it off for at least a week. The problem is that moisture gets inside the phone itself and just takes time to evaporate. If you turn it on or leave it on after water gets in you run the risk of shorting something out and killing the phone (which is what sounds like happened). As far as repairing it is concerned, might as well get a new one, it'll cost less.
your phone should survive just give it some time in the rice, my brothers samsung ace went through something similar and he put it in rice and it was fine after a day buried in it, there is videos of the moto g submerged in water for a while and still works fine
good luck

Water resistance question

Hey all, new owner here. So I spilled some ginger ale on my phone, not a lot, but I thought well hey, this phone is water resistant, I'll rinse it off. So I rinsed it off in cold water, and put it under and inch or so for cool factor for a minute or so. I then dried it off, and shook it to get the water out of the ports. All seemed fine, but an hour or so later I went to use it, and the screen wouldn't turn on. The back/recent lights came on, and the blue notification light came on for a bit too with more prodding, also the screenshot combo seemed to work, and seems to have taken a picture of the lock screen. I let it sit for another half hour or so, at which point I tried power/volume down or up, can't remember, either way it rebooted. Finally it's on now, I use it for a bit, and it does the same thing. I let it sit another 10 mins, and do the button combo again. This time it seems to stay on. I charge it that night, and unplug it once it's charged and turn it off. the next morning I turn it on, 92% battery left. Weird. Using it through the day today it doesn't seem to be draining extra fast or anything. Is this anything anyone else has encountered? Should I be worried?
Needless to say I'm a little scared to test water resistance any further right now...

Have to say that in my opinion the phone is really water resistant. Tried it in normal and salt water couple of times exceeding the recommended 30 min. Even use it underwater to take pics and videos. Probably you should dry it very well. After every water situation i noticed that it wont charge until the connector is completely dry. Sometimes the phone says that 3.5 mm jack is in use (can assume that water is fooling the software) Just try to dry it really well and maybe is just a coincidence and your firmware is faulty. Than reinstall using odin and if the problem persist - claim waranty. Good luck
