In the water - Samsung Galaxy A40 Questions & Answers

Hello
My phone fell in the water. He dried up. It works perfectly except when it comes out of standby: I have to go through the mains socket because the button on the side of the device doesn't seem to work anymore... do you have a solution?
Soft reset is ok.

Find a procedure to crack open the phone.
Scrub the electronic parts with a clean toothbrush doused with isopropanol.
Reassemble the phone.
Test and validate !
NB:
You cannot fix a hardware damage with a software solution (at best, it'll be a workaround).

Dropped my Jasjar inside a WC :( Please advice

It happend while I was taking my cloths off for taking a bath
I dropped it inside our WC and my 2GB SD Card was gone far away inside that damn WC and never found it
I tried to pull out the battery but I couldn't pull that damn battery out for 5 min.
Anfter 5 hours drying with a hair dryer I put the battery and other stuff back and there was NO life After pushing the softreset hole some 10-20 times and putting it to charge there was a little life back some blue lines at the screen.
Now after 5 more hours it starts, but after some resets (some times there is only blue lines) and when it starts it freezez very much...
Should I send it for repairing?
Does the worranty covers it? (I bought it from Internet)
Would reflashing help?
Please advice...
tbh, I would have left it to dry normally in a warm place for 24 hrs before even considering to power it up, as (not 100% certain) I think the hairdryer creates static, which could damage the electronics inside, plus, you can't guarantee that it will have dried it out completely, which means, when you started it up, it could have still been damp in the middle and damaged something.
does it look like it has been water damaged? if not, then your best bet would be to not mention that fact, and just say it has suddenly started being funny, not booting up and freezing alot.
I doubt a reflash will fix it, but it is something for nothing, so worth a shot, however long it is.
*edit* if the company won't replace it, you could try your house insurance...
Thanks alot for the reply wytey,
I think there is something damaged, becouse when I soft reset it after freezing there comes a couple of times a light blue screen with blue and white lines...after soft reseting 3-4 times again it loads normaly again but freezez after 5-10 mins again
I was soo happy with my Jasjar >:'(
Your device has been damaged by water.
This is not covered by warranty.
It might not be covered by any insurrance you might have through your service provider.
You may be able to get it covered under home insurrance.
There isn't a case for a wet PDA. But I've read a recent article of getting back a Linksys router that has been soaked wet by rain water. See the real life experience here
http://www.grynx.com/index.php/projects/salvage-your-device-after-liquid-spill/1/
Probably you can do the same?
I dropped my Wizard in the bath, took out the battery and let it dry for about a day or so. Evrything works just fine.. So you should have dry it for over a day or more to be shure no water is left in it
Very timely.

Thanks for replies guys,
Usefull article, but I think it's too late now, I couldn't take out the battery for 5 mins, then how to open the device and clean the components/circute
Can they prove it if I don't mention water?
Home insurrance would be a big lie, but who cares they get money from me every month (what to say to them? stolen? bropped in water?)
Thanks again for your times guys
I may be wrong , but I beleive there is an "indicator" in most modern equipment that shows up if there has been any water damage
anyone who knows how to repair phones and look at pcb boards etc. will KNOW right away that it has been water damaged. Impossible to hide (unless you yourself are also a technician).
I know because I own a phone repair shop and have been doing repairs for a lot of years.
One of the IC may be damaged, so when your device starts to get warm (as you said 5-10 mins) it cannot hold the power.
Just think yourself lucky that it's only an IC and not a CPU.

THanks alot for the info hb328_dtdd
If it's an IC, is it hard to repair it? how much would it cost me?
thanks
I (or whoever you decide to check the device) will have to open the unit up and clean out the residue of water and then do thorough tests first, it may not be an IC problem, even if it is an IC problem it may not actually be broken and will work again after cleaning and sonic waves passed through it.
Depending on which IC is broken and how hard it is to replace it, and also if it has caused any other side effects to the other chips, the repair in theory should not cost too much at all as it does not seem serious (from what I read from your post anyway).
E-mail me with more description of the problem and I will try and give you some tips to get it running, if that fails then you can decide whether to send it away or take it to local engineer to repair.
Hope this helps
the Gadget (Ch 5 UK )show did a piece on stuff getting wet. I htink they all came back to life one way or another but the were left to dry slowly I think for a day or 2. so you could hold out for live in the thing yet?
I hate the fact that Dopod 900 is very slippery, don't you think? I'm looking for a rubber casing like the one for O2 and Ipod.
Dopod 900 enclosure is too slippery, I'm so worry I may drop it too.
I am selling some Pocket PCs and this happened to two of my customers. But the device was an Ipaq 37XX and 38XX.
Both devices I put on a warm place and left there for 4 days. Then after this I powered them up. The Ipaq 37XX had only a bad LCD light, which was flickering sometimes and was not bright. the 38XX worked good again.
Anywasys, you need to check your device and have it cleaned. The biggest problem is the fact that there is so little space between smd mounted chips and the PCB that the water stays in between never drying and makes the metal rust. I had this experience with a cell phone already.
So you can try following:
(1) pay for cleaning and repair
or
(2) try to get it guarantee exchanged, which is also possible as for a pocket pc the technicians normally do not check for water damage. But if you have bad luck, somebody will notice this and you get nothing replaced.
I managed the same thing a while ago with my Xda2, and the symptoms were pretty much the same when it first happened (random lines and 'blotches' across the screen, freezing)..
Without haste, I removed the battery, sd card and mopped up any moisture from inside the battery compartment.. placed it in a warm place in an attempt to evaporate the moisture from the device. I left it for 24 hours before powering the device back up.
It DID work afterwards and I was a bit suprised and relieved at its resilience to liquid.
The important thing is to make sure the board and pins of the chips are not shorted by liquid, if you cannot get to the board, evaporation in a warm place is probably your best bet...Just watch out how you apply heat for the sake of the screen (and possibly the keys on the exec).
I dropped my XDA II into a canal and managed to save it. The problem is the water can't evaporate easily. I took the battery off and put it on a radiator. It took 7 days to finally dry out! It worked ok though.
You probably still have water in yours, so I would recommend putting it on a radiator or somewhere hot and just leaving it. You haven't got anything to lose
After almost 2 days inside the radiator it still has the same freezing/dying problem I thinks something is damaged inside ((( And now I can't find any electronic service in Denmark who can repare it
just because it's dry doesn't mean it fix itself, people often mistake this. Sometimes people get their phones to WORK after it's DRY but little do they know what is really happening inside the phone each time they power it back on and the residue is still there inside the phone lurking in the spaces between the pcb and the chips.
no matter what anyone says, I always tell people the same thing:
YOU MUST GET IT PROFESSIONALLY FIXED
My suggestion and this has never failed me yet.
1. After being dropped in liquid, DO NOT SWITCH ON - This is where most of the real damage will occur. If it is/was switched on remove battery as quickly as possible.
2. Strip down and remove any thing you can do easily, covers, sd card, stylus, sim, battery.
3. Waste a whole aerosol of switch cleaner, squirt it anywhere and everywhere you possibly can, literally fill it up with the stuff so it is pouring out of every hole. Do NOT use WD40, it must be electrical switch cleaner that will leave no residue at all!
4. Allow as much as possible of the switch cleaner to drip out and then allow it to dry, do not force dry with a hair dryer and even a radiator is too harsh. I find airing cupboard where the hot water tank is is the best place.
5. Leave at least 48 hours before putting everything back together and switching on, if it does not work straight away, strip it down again and leave another 24 hours, keep repeating for 7 days.

URGENT Problem with HTC Wizard WM5 doesnt boot

Hi,
I have a problem with my SPv M3000/HTC Wizard/Qtek etc.. A bottle of water spilled in my bag and my pda became Wet AND now it can't boot the os - windows mobile 5. When I switch on the pda on the screen appears a picture with a name of my network [Polish Orange]and 4 lines of numbers :
IPL 2.22.0001
SPL 2.22.0001
GSM 01.04.10
OS 2.22.1.1
To switch of the phone I have to remove it's battery. Btw. a button to switch on and off the pda is a bit pushed but it works quite good.
Charging works, battery works.
I tried to make a hard reset of the pda but it didn't solved the problem.
Btw. I would like to ask you for a fast and urgent help because I'm abroad and I need my phone very much and something with alarm ;(. Unfortunately I have aslo limited acces to the internet so I 'll be very pleased and thankful for your help
Hmmm, there may not be any help for your device...water and fine electronics DO NOT mix! I would try however, take the battery out of your phone, and leave the cover off of it for a few hours, perhaps even with the keyboard extended, and see if the internal circuitry will dry out. You could also try getting ahold of a hair dryer and setting it on LOW, and doing it that way...just be VERY careful if you go down that path, as hair dryers can get EXTREMELY hot!
There are few other alternatives depending on how desperate you are:
2) an oven at Low heat (150 degrees F or less) for maybe 30 minutes as an alternative to the hair dryer.
3) a bag full of fresh Silica Gel to leave the phone in overnight.
4) a high quality isopropyl alcohol: soak the phone in the alcohol, which should displace the water, allow to dry for several hours.
If you have attempted to turn on the phone while wet, it may have already shorted something out.
I would use any of those at your own risk...the alcohol bath seems is probably the most risky and the Silica Gel the least.
Hi again,
I don't want to try your methods because their sound dangerous ;]. I tried only hair dryer but it didn't help ;(.
What do you think about reflashing ROM?

Yup ! very right, what 'ashasaur' posted above "Hmmm, there may not be any help for your device...water and fine electronics DO NOT mix!" unless your phone is completely dried it won't boot or work and I wud rather warn you here,if you persist with turning on the phone like this it'll short circuit and become dead and useless.The only way out is to completely strip or dismantle the phone of its covers and cleaned throughly.
Secondly,its not possible to reflash in this scenario ,as it doesn't boot up,you wud be lucky,if it boots up and start working,after proper cleaning,so stop beating about the bush and start thinking positively,get down to try to dry and clean the phone first.
There's no danger in using the silica gel. It's a desiccant packed with most electronics. Combined with dis-assembling it could be effective.
I agree the other two are pretty scary!
ahhh...very right! I didnt even think about silica gel...or more comonly known as "painters desicant". It does indeed remove the moisture from the air and from any surface within the area...that would be the best choice. The only reason that I recommended the hair dryer was from my own experience with a Palm Treo 650...I dropped it in a glass of water(lol), and dried it with a hair dryer for prolly 20-30 minutes on LOW, and it started to work again!
Desiccant can be had very cheaply, and in large quantities. Just go to a mega store like WalMart, go to the storage section, and look for "cabinet and closet dehumidifier". Remove all the seals and drop your phone right into the pebbles overnight, and that'll take out any moisture.
If it still doesn't boot, no changes of software (flashing) are likely to help. Not booting after water exposure usually means a circuit was shorted. If drying doesn't remove the short, that means something was fried when it shorted. Sorry. Next time get insurance!
I have a warranty for my pda and I dont think that people who will repair my phone will notice what caused damage ;].
But i think i m going to check thaht dehumidifier it sounds quite interesting ;].

trinity on the water

Hi, three days ago my trinity fall off in water( in a pool) .immediately i've dissassembled it and cleaned it and putted to dry.Now It works perfectly except the radio( "no service") and gps.
There is more can i do?
Thanks and sorry for my english.
You can try once more disassembling and clean with a contact cleaner and then reflashing the Radio part,good luck!
A friend of mine did exactly the same thing... And trashed his Li-Ion battery too - they really dont like exposure to any mosture!
From what you say, I'm guessing that despite your attempts to remedy, there's a reasonable likelhood that there's still moisture inside your unit. Probably trapped under the low profile ("surface mount") ICs where its the hardest to dry out and can cause the most havoc if it contacts any IC pins.
I suggest you disassemble the unit again and inspect carefully for any signs of moisture. Even if you cant see any it may still be wise to use, say, a hairdryer or similar to force out any trapped moisture. A good, long session afterwards, in a warm place e.g. an airing cupboard, might help too...
Not nice - good luck!
my friend im going to give you a hint that usuly works on electronic devices,
1º try weting the board of your trinity with pure alcool ,because the alcool brings all the water to the surface and then it ends up evaporating
at least it works on mobile phones!!!!!!
give it a try
2º only turn on the divice after its dry
good luck
p.s
i have a feeling it´s going to resault
I confirm that the alcohol procedure is the right one - by experience! i was told to do it as soon as possible after the immersion, to avoid oxidation of the electrical contacts. In addition, i would suggest isopropylic alcohol (if you have it) since it has a larger molecular weigth and it will leak less into the packaging of the IC - which unfortunately are VERY moisture sensitive...

Fix dead touch screen?

Today my U8800 seems to have decided not to work. Most of the touch screen is unresponsive, and only patches work. The lower right is completely dead including the soft keys
Any idea on how to fix this?
I had a wee bit of water sitting on the screen for 10min, would that cause it? I just had quite wet hands and used the phone and didn't dry it off. Apart from that, no idea what could have caused it
Assuming I can't get a replacement since I bought it in NZ and now I'm in UK
If the problem was indeed caused by the water, try the following:
Open the backplate, remove the battery, sim & sd card and let it stand for 24h in a dry place (don't use a hair dryer or any similar "clever" ideas; an oven is right out).
You may be lucky and salvage it, assuming the current from the battery isn't strong enough to have caused a short-circuit and that it hasn't touched anything crucial & sensitive. Good luck in any case.

Stuck in fastboot with Device Status Locked after dropping in Water. Tried everything

Hi guys, I have dropped my phone in water and now I am stuck in fastboot mode with Device Status as Locked. I have tried every possible things, followed (https://forum.xda-developers.com/oneplus-3t/how-to/unbrick-unbrick-tutorial-oneplus-3t-t3515306) as well as (http://www.androidbrick.com/unbrick-oneplus-one-two-3-3t-qualcomm-hs-usb-qdloader-9008/) after doing all steps my phone again comes to fastboot mode and I can not access recovery mode. Can any one please help me. Thanks.
Time for a one plus 5
Did you disassemble it to dry the components? Water contains minerals, some of them are conductive. Unless these parts got cleaned with e.g. alcohol, there's a chance that you still have currents flowing where they should not. Usually you can't do that much damage to PCB etc. with water, but connectors etc. really don't like what is left when the pure water has evaporated.

Good advice. Denatured alcohol leaves few conductive impurities behind, so is a good cleaning and evaporative solution.
Also a good idea to disconnect your battery while cleaning.

Bro but I can go in fastboot mode and can complete the process in Msmdownloadtool v3.0. However, after it shows "Download complete" my phone again boots to fastboot mode with device locked status. Is it possible that their might be some water left in my phone which is not allowing me to unbrick? (I am not a guy who can understand hardware so I am afraid to open it) Thanks.
If you have toothache, you got to a dentist. If you don't know how to open a phone and are afraid to do so, go see someone who can. It was in water, so it needs to be taken care of as it's not working as expected. You've lost your warranty anyway, so my best guess would be to open it up before sending it back to have it repaired.

Hey, I went to repair shop and he removed water with isopropyl alcohol. (charged me $50) but refused to work on software part. I have tried MSMdownloadTool but even after "download complete" my phone boots in Fastboot mode only.
