[Q] Galaxy S3 I9300 on but screen off :( - Galaxy S III Q&A, Help & Troubleshooting

Ok so my little brother was playing with my phone yesterday, and I believe he put it in his mouth and the charging port was in aswell, and it got a little wet. I dried it with a towel not knowing that it had gone isnide and the phone seemed to be working perfectly. I few mins later I was making a skype call, and out of a sudden the screen started flickering and just sit down. I though it was the sensors picking up something, but i Put my fingers over them and could still see that the screen was off. But the call carried on and the phone was still on, it was just the screen which was wet. So i decided to take the battery out, and when I took the back cover off, i found out that it was all wet. I de assembled my phone cried it all even the screen connecter and no internal damage had been caused from my perspective. I cleaned the motherboard battery everything. There was no signs of water on the inside it was only on the back cover. I still dont understand why it wont turn on, it never had any impact it just got wet and I cant see and signs of it inside the actual phone. I also cant get into recovery or download mode. PLEASE reply ASAP thanks guys

Water damage is death to smartphones, your motherboard is probably blown.
Try placing it inside a ziplocked bag of rice in a warm place for a day, but it's probably too late.

If you can't get into download mode try a usb jig (very cheap off ebay) if then you can get into download mode flash a stock firmware if problem is still their then it is a hardware problem. Sounds like some water damage somewhere (maynot be visible) but usb jig is worth a try

[Q] HD2 not booting, starting up

Hello,
Saturday I went out, my HD2 only had like 5% battery life. I used it till it went black. The day after I wanted to recharge my phone but when I plug the microusb in to the wall charger, no led lights come up. When I press the power nothing happens. Stays black, it's like a dead stone now. I did not flash the phone for the past 2 months, it's running android already a long time now.
This morning when I pull the battery out and put it back in and push the power button then a VERY short vibration comes out of the phone but then nothing anymore the screen and leds stay dark. If I try it a second time nothing happens. So I think the battery is 99.9% empty and I can't charge it anymore through the microUSB. The only thing I can think of what happened is saterday I took a bath and my phone was lying on the edge of the bath, it did not fell in the bath offcourse. But there was alot of humidity in the bathroom because of no ventilation and warm water. The phone was working perfectly after the bath and stayed working untill the battery went to 0% when I was going out. Is my microUSB port water damaged? The stickers inside the phone are still white. (luckily). Anyone has an idea how to fix it or what the problem could be?
Remove the battery.
Connect to the power supply.
After a couple of minutes, plug in the battery (while the phone is still connected to the mains supply).
Ok I tried it.
Took battery out. Connected to usb power cable.
Waited +- 5 minutes. Inserted battery -> nothing happens.
Won't turn on, no led lights.
BUT I noticed a strange thing.
If NOT connected to power cable : Take battery out, reinsert. Power on, -> some milliseconds of vibration.
If connected to power cable : Take battery out, reinsert. Power on, -> nothing, no vibration.
So if it is connected to power cable phone acts completely dead when I reinsert battery and push power button. But if it's not connected then when reinserting the battery and I push the power button then a very short vibration is felt.
Weird ... is there something shortcircuiting the phone when connected to powercable??
Ok,
I found someone on my work who has an HD2 like me. So I tried to put a 70% charged battery in my HD2. Guess what ... same result. A little vibration and it stops .
So now I know it is not the battery. It's the phone itself. I've put it now in a bowl of rice and hope next morning it will be magically revived. Maybe when I took a bath saturday there formed some micro water bubbles inside the phone and it still isn't gone by now? I am out of ideas. If this rice thing doesn't work I'll send it to HTC repair centre. They won't notice my hspl because they can't even turn on the phone with a charged battery. I'll guess they'll swap the mobo .. again. My previous repair was because my HD2 was in a constant Carkit mode (also a hardware issue). Sigh
Can you get into Bootloader Mode (Press and hold the Volume Down button, then tap the Power button)?
Nope, it acts like dead meat, even with a charged battery I could try from my friend his hd2. My battery worked in his phone. So it is my phone who is broken.
Think some hardware is busted ... Maybe some circuit is broken ? I just don't know . Now they must repair it for the second time. The first time I got the "phone is always in carkit modus" issue which is also hardware related. I hope they will not make a problem to give me yet another motherboard and yet another IMEI . That will be my 3rd IMEI on this phone then.
Hope they pick it up tomorrow .
K Update to this post.
I've received my HD2 back from HTC repair with a new motherboard / IMEI.
All is working now again .
I am afraid it can happen again . This is my 3th IMEI / mobo now on this phone after owning it a year and 2 months.
They now also didn't put a new "VOID" sticker on the screw
Also no "water detector" anymore.
It seems like they are saying to me, now if the phone breaks again, you have no warranty anymore. It's not my fault the mobo suddenly dies . I doubt it they just "forgot" to put new void stickers on.
Never take cell phone in the bathroom.. especially if its a touchscreen.. the steam from hot water gets accumulated inside the phone and ruins it. My friend damaged his 2 handsets already.. now he doesnt take it in the bathroom anymore

There are water dector labels inside the phone and if they forgot the VOID label then that is their problem. You have twice returned the phone and by replacing the motherboard they have admitted that the problem is theirs. So they already have a history of faulty phones from you and since it has been repaired by them, then they would need to show a record of placing a viod label back on the phone.

Well I also think that was the cause the phone died later that evening.
I think the phone went dead sometime that night because of the water inside the phone. Luckily the water detection labels where still white .
I never will let it inside the bathroom again .
As for the void sticker problem, I will contact them to ask why they didn't put on new stickers. If they don't respond I saw you can buy such stickers on ebay .

[Q] Random turn offs.

Helpp!!!!!!!
Dropped my xperia mini and it got very slightly wet.
It didn't turn on when i tried.
I took out the battery, wiped it and put it back in.
Then it booted normally. After a while it shut down.
And it didn't turn on. Then I started charging it after about 15 min of not responding it turned on. It was charging till 20%. Then when i started using it for a bit turned off. Now waiting for it to turn on.
What should I do?
Should I get new phone with warranty?
Or is there solution?
Thanks in advance.
Had two incidents like this, the first incident shorted out my phone (just one second in the water), the second one I wiped dry, wrapped a piece of cloth around it and put it in a sack of rice to absorb the moisture (googled it).
Moral of the story: Never turn on a wet cellphone immediately (even after wiping it dry) lest you want a shorted out unit.
Dunno if doing the latter will make much difference seeing as you turned it on and charged the unit. If it is still under warranty you can try to have it fixed, just don't mention the water incident (though there is a possibility they might find out even after it's dried, dunno really)
-Xaeons
Thanks my friends told me not to turn it on straight after i wiped it so am getting it fixed.

[Q] S2 thinks it is charging all the time

I had a minor incident the other night, whereby the (USB) end of my power charger got water on it. I dried it off instantly as best as I could. The phone itself has not come into contact with any water.
It still charged the phone fine... however after removing the charger at 100% the phone continued to say charging. I turned it off and removed the battery for some time. Upon putting the battery back in, the display showed the charging animation again even though it wasn't plugged in. At this point it wouldn't even turn on.
After multiple attempts I managed to get it switched on. But even now, 2 days later after a couple more charges, it still says it is charging when it isn't. The battery % is also depleting a lot quicker than normal.
I tried a factory reset, wiping and installing a new version of the AOKP ROM I use which fixed the issue temporarily... but as soon as I try charging it again, the charging animation won't go away. This happens even with a different charger all together or a USB cable.
Any ideas on fixing this, or is it time to claim on my insurance? Thanks!
may b the enternal is still not dried , actually wen wet its best to dry it in rice bag for a day or atleast 16,20 hrs then clean an use a sylte warm or cold blow so the moist drys out...so first open the back cover,battery ,sim,sd card an let the phone dry properly..cheeeerz
Thanks but as I say, the phone itself never got wet. Literally a minor amount got on the charger... not sure it is worth drying out a phone that never got wet?
but the end of the usb port is wet right so dont do the charging thing jus use a blow dryer let the thing dry out ,i had dropd my phone in luke warm water of bucket ,i removed it an took out battry,cover and kept in rice bag water was all inside cause wen i checked by shaking it ,i could see water coming then i used a blow dryer an dried it but i had kept it rice for hmmm i think only 2,3 hrs ...but i dint on it for 6hrs like tht....then the next day i powered it an all was fine ..accept the speaker at the back but i used a app tht was supposed to clean speaker,well i don kno weater it got well on its own or the app....well thts my story...m8
be careful with the hairdryer though i know people who have melted plastic drying with a hairdryer xD
did you actually found a way to fix it? i have this problem. and i havent been able to fix it.
Also my PC wont recognize the phone.
Try to clean the usbport. If it doesnt work it needs to be replaced. Its fairly easy and cheap.
Theres guides on youtube.
Well i didnt follow a guide on youtube i just opened it used a toothbrush and alcohol and after with a bottle of suter and it kinda worked, the computer recognizes it but the charging thing is still on.
Im gonna check out the youtube videos.
Thanks!

Dropped phone down the bog. Its working again but has overheating prob. Pls help

Ok, Here's what happened
I was cleaning the toilet at home and foolishly placed my phone on the tank, as I finished I picked up my phone, slipped out of my hand and fell in the toilet. I know I know, why did I take my phone to the toilet? I have no idea, its the first and last time have done that.
Anyway, I removed the battery, sim and sdcard straight away and tried to dry the phone off as much as possible, then placed the phone and battery separately in a concealed bag filled with dry rice (to absorb moisture), I can now boot my phone.
The problem is that the phone says I need to charge my battery, now when I try and connect the charger, it says, 'Charging has stopped due to overheating'.
My question to all you pros, is this a battery or phone issue? I don't really want to order a new battery to find it's a problem with my phone. If it helps, when I tried charging it, I noticed excessive heat down one side of the phone, as shown in the attached image.
Be gentle :crying:
...
You didn't mention how LONG you kept the phone components in bags of rice before trying to reassemble and power the phone.
If it was anything less than several days (if using rice as a desiccant, most recommendations I have seen are a week, minimum) and this is the only technique you attempted to use to dry the phone out, then it is very likely the phone was not completely dry when you powered it back up, and you may have permanently damaged key electronic components by allowing an electrical charge to flow through them before they were completely dry.
MistahBungle's call of the board responsible for the USB port is a good guess on which component, though.
Thanks for your replies guys.
I only kept it in the bag for 48 hrs. As you mentioned this probably wasn't long enough. I may just try and claim through our house insurance as it does cover smart phones, I don't have normal phone insurance because I've never needed it until now.
Thanks again for your help.

[TUT]To fix a water damaged Neo V

This was my question before I converted it into a tutorial:
Sorry if this question was posted before (I did ask this in the NOOB-FRIENDLY thread, but didn't get a constructive answer)
My Xperia Neo V dropped into water.
Dried it with rice for a whole day and turned it on. Success! Was able to even play games.
Then I sent it for charging. (Battery was 8%)
5 mins later, it died.
Responds by entering flashmode after blinking red LEDs (3 I think), so I flashed stock.
Still couldn't start, so I sent it for charging (No response either after some hours)
I abandoned it and switched to a Galaxy Ace...until now....
Connected it to PC a month later.
It blinks red LED continuously, unplugged it and plugged it to a charger. No LED response whatsoever.
Plugged to PC again and POOF! Magic.
Detected by PC as my old MT11i :'D
LED is green, can do file exploration. Buttons are lit, vibrates when I press shutter button. No sound with the volume buttons
So the verdict...
CAN I STILL REVIVE MY NEO V?
IS MY DISPLAY DAMAGED?
This tutorial was made possible by @xange and @georgeiulian89. Thanks!
Usually when you drop your phone, you would be doomed. Or so you thought. With this tutorial, you can save A LOT of money buying a new phone or repairing the wet phone!
HOWEVER, I CANNOT GUARANTEE THAT YOUR PHONE CAN REVIVE. THIS WORKED FOR ME (SHALLOW DIP IN WATER). YOU MIGHT ALSO NEED A NEW BATTERY (IF YOU THINK YOU CAN REVIVE IT)
Steps(suggested by xange, proved):
1. Remove your phone from the water source IMMEDIATELY! (duh) DO NOT ATTEMPT TO SWITCH IT ON OR PRESS ANY BUTTON.
2.Remove the battery, SIM and micro SD cards.
3.Dry the body with a dry cloth. Try not to use tissue paper as it will leave residue.
4.Disassemble the phone, all the way to the motherboard. I used a small slotted screwdriver (the one with only one edge)as there are screws shaped like stars. If you have that type of screwdriver you can use it. Similar disassembly video here: www.youtube.com/watch?v=ginuDIeNCs8
WARNING: INTERNAL PARTS ARE VERY SENSITIVE TO STATIC, METAL,ETC. BE CAREFUL. ALSO REMOVE THE CONNECTIONS TO THE FRONT COVER AND DIGITIZER (display) BEFORE REMOVING THEM.
5.Direct a blowing fan to all the internal parts to dry them. Keep the screws and parts in an accessible area. Leave it for 30 minutes. DO NOT DRY IT WITH A HAIRDRYER. YOU ARE JUST TRYING TO SCREW YOUR PHONE.
6.Reassemble the phone and insert the battery ONLY. NOTE: Make sure the ribbon connector is clean before connected, if dust (or any tiny electric conductor) sticks on the connector while connecting them, you will have high chancesof damaging the phone. Then, switch on the phone. If not,
A) CHARGE IT: Your phone battery might be 100% dead(until normal charging can't power it on). For me I pressed and held the Back button while plugging the charger into the phone (Flashmode). The LED should blink red and eventually, green. This is when normal charging starts.
B) REPLACE THE BATTERY: You'll need to do so especially when the (once)white area near the connectors of the battery has turned red, indicating battery damage.
C) SEND IT TO A (optional: AUTHORIZED) SERVICE CENTER: Out of luck. This is the furthest I can help.
ALTERNATIVE DRYING METHODS:
A)PUT IT IN RICE FOR A DAY: NO, Asians won't come to repair your phone. Rice acts like silica, which absorbs moisture like sponge. I suggest you disassemble the phone first as rice might get into the small holes around your phone.
B)SOAK IN ALCOHOL, THEN PUT IT OUT: Disassemble it first, too. Though I haven't tried this method, there are those who have proved it to work.
C) RADIATOR DRYING (suggested by georgeiulian89): I've turned it off,i've removed the back cover, took out the battery, sim card and sd card, and i've put the phone on the radiator (i've put a towel between the phone and the radiator and i've placed the phone on the towel). I've left the phone about two hours to dry, and then i've inserted back the sim, sd card and the battery and turned it on.
C)DRY IT WITH A HAIRDRYER: NO. RISKY METHOD. Water will evaporate, then condense back somewhere once you've done hairdrying your phone it will condense back. I tried it and it condensed on my phone's camera lens. (It's a hairdryer, not a phonedryer!)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Hope this tutorial helps those out there whose phones have went swimming (or diving)

I dropped my Xperia Neo into water for 3 times, yet still operable, i mean, it survived 3 times of dropped into a pail of water, NO JOKES! .
What you should do is, the moment you dropped your phone into water, pick it out of water immediately, open the back cover and take out the battery immediately to prevent further electric short circuit. You will need some small tool to open every single screw to get the mother board come out (careful when unplug those ribbon sockets, if it breaks, you may have to pay to replace it) and dry (using hair dryer?) every single spot in the phone, except the screen, the screen should be tightly seal and should have no water enter into it. maybe the rubber physical buttons you have to take out and dry it too. (DON'T open the screen no matter what happen, unless water really enters the screen, or else the dust enter and stick at the screen you will have a REALLY HARD TIME { i mean it } to clean those dust out of the screen) confirm everything is dried and then assemble it. (from here onwards, it is a luck test whether you still able to save your phone or not, a line between hell and heaven) Put in your battery, It is normal you may not able to turn on your phone at first, give it a charge about 20 minutes and leave it there (red LED may blink repeat-ly for a while and you will not able to turn it on, just leave it) then switch it on, If you still can't turn it on, try change the battery. If symptom persist, god bless you, i tried my best helping you. ( it means it may not 100% probability to save your phone, but it is a way i did to save my phone)
Eventhough my phone survived dropping into water for 3 times, but it has some problems now, a random one, the phones get really really hot for no reasons for a short period (about 1 hour to 2 days) the heat comes from the motherboard after my inspection, maybe some water droplet enter into the chips and causing electric short circuit?
Good luck.

I followed a disassembly video for the Neo, but unfortunately the Neo V has a slightly different assembly, so I could not remove the screen to get access to the motherboard. Also, before I put it in rice, I tried to turn it on (Sony said it was water-resistant) after 12 hours in rice. The screen went all weird but I could hint the LegacyXperia kernel logo. That was before my phone booted up normally, and died upon charging.
For your heat problem, perhaps rust? Water should have evaporated from the heat and condensed everywhere in the motherboard.
Would soaking it in alcohol help?

I guess that it's a problem with the battery, not with the display (probably the battery has been short-circuited). I dropped my phone (Xperia Neo) in water 3 days ago. I've took it out after about 10-15 seconds (this was the time until i've realised that it dropped). The phone was still working fine, it didn't shut down by itself. What i did: I've turned it off,i've removed the back cover, took out the battery, sim card and sd card, and i've put the phone on the radiator (i've put a towel between the phone and the radiator and i've placed the phone on the towel). I've left the phone about two hours to dry, and then i've inserted back the sim, sd card and the battery and turned it on. Gues what: it works without any problem, just like before the incident. You should check the water damage indicator on the battery (it's a white strip near the connectors of the battery). If it's white, the phone don't have any problem, but if it's pink or red, the phone was damaged by the water. Mine it's white, with some very little pink on the edge (before it was completely white).

Thanks for the tip but in all-summer Singapore we don't have radiators.
UPDATE: After following steps by @xange to reassemble and charge my Neo V, it BEAUTIFULLY WORKED!
The catch: Battery calibration problem, stuck at 100%. I'll figure a way out. Thanks a lot devs!

To get rid of 100% battery issue, you might just want to flash stock ftf in the first place, give it a full charge and then flash your desired driver.

C) SEND IT TO A (optional: AUTHORIZED) SERVICE CENTER: Out of luck. This is the furthest I can help.
ALTERNATIVE DRYING METHODS:
A)PUT IT IN RICE FOR A DAY: NO, Asians won't come to repair your phone. Rice acts like silica, which absorbs moisture like sponge. I suggest you disassemble the phone first as rice might get into the small holes around your phone.
B)SOAK IN ALCOHOL, THEN PUT IT OUT: Disassemble it first, too. Though I haven't tried this method, there are those who have proved it to work.
C) RADIATOR DRYING (suggested by georgeiulian89): I've turned it off,i've removed the back cover, took out the battery, sim card and sd card, and i've put the phone on the radiator (i've put a towel between the phone and the radiator and i've placed the phone on the towel). I've left the phone about two hours to dry, and then i've inserted back the sim, sd card and the battery and turned it on.
C)DRY IT WITH A HAIRDRYER: NO. RISKY METHOD. Water will evaporate, then condense back somewhere once you've done hairdrying your phone it will condense back. I tried it and it condensed on my phone's camera lens. (It's a hairdryer, not a phonedryer!)

add in: make sure the ribbon connector is clean before connected, if dust(or any tiny electric conductor) stick at connector while connecting them, you will have high chances to spoilt the phone.
