Hi everybody!
I am experiencing a new kind of problem in my sgs2,
Last saturday a glass of water droped on the floor and some water wet my phone. It was on, and it didn´t switched off. I did it by myself and took off the batery.
But when I switched it on again a yellow triangle with a thermomether appeared in the screen. The sgs2 seemed to work right, but it began with some problems. First of all, I couldn´t switch it off, once I did, the phone rebooted itself. Then it appeared at the top the sign of "mtp initializing" even when the usb wasn´t connected. I took the batery apart and tried to see if there was water inside. I blew and some water went out of the phone.
I remark that the only part that got wet was the usb (even inside) but the water didn´t touched the screen and nothing else.
After a couple of days, the phone didn´t recognize the usb cable when it is connected. And when I charged the sgs2, it was ok at the begining.
But, yesterday, the phone stopped detecting the charger when it is connected. Even more, to charge the cell, I have to switch it off and connect the charger, doing this, the telephone reboot and begin charging.
Nowadays, the only way to charge the phone is what I´ve related. Furthermore, it didn´t detect the usb when it is connected.
Ah!, just the week before this accident, the sgs2 reboot itself many times and vlingo activated itself. In spite of the fact that the battery was full, in some reboots, after rebooting, it showed me %10 of battery. Then when it rebooted again it showed me the correct percentage.
Considering I´ve no warranty, I opened the phone and checked if the "usb block" got wet and at first sight it was perfect!
Except for this issues, the phone works great. Even more, I flashed it by CWM (just in case it was the rom) and nothing got fixed.
I ordered a new brand "usb block", and I am waiting for it to arrive.
Does anybody know anything useful?
Thanks a lot! This is a great community, and if you don´t know nobody will.
Hello, same problem here. But without any water!!! I will try today to clean up the usb connector without battery in the phone. And I will see.
If you can try it also...
I was having the same issue. And I am not sure this will help, but I read on net that at times with Galaxy S people faced this issue and was related to files with very large file name. So I checked my download folder and indeed I had a wiered file with eBay something. And surprisingly, after I deleted that file, things are again back to normal for me.
Thanks,
Vishal
after few weeks I know that it works!! you have to clean up your connector from a dust

Has anyone had this problem?
After three trouble free months, my phone has developed a a very strange problem.
After charging, it behaves as if I'm constantly connecting and disconnecting the phone to a PC. It bleeps whilst showing the battery being connected to a charger and then imidiatly acts like its been disconnected by bleeping and running media scanner on both SD cards. It also shows that its connected via Kies, even though all this is happening whilst only being connected to a charger!
I've already done a full reset, which helped for a few days before it came back. It normally sorts itself out after a few minutes but the period before it "calms down" is getting longer. This morning I removed the battery for an hour but it continued in its "loop". Another, possibly related symptom is that as soon as the battery is installed, the phone boots up without being switched on. The same thing happens if I shut the phone down, it just powers up again!
Any thoughts?
had you if ever dip the bottom part of your phone? sounds like short-circuit issue or I maybe wrong.. try bringing in on to the nearest service center for warranty
Sounds a plausible theory but as far as I can tell, it hasn't got wet. Its been doing it for a few day now, so I think if it was damp, it would have dried out by now.
Thanks anyway.
I got the same problem. Let me know if you figure it out.

my friend had a simmilar issue and it was damage to the usb port , it kept thinking it was connecting to the pc or charger , it also wouldnt charge when plugged into a wall point and went into usb mode and vice versa when he put it into a pc
he sent it back for repair and they sent him a new phone
it may not be what you have but it does sound simmilar
i would try a few things like a reset , format the mass memory , install firmware again , dont restore back ups but set phone up fresh like you would do if you just bought it , then see how it goes , it could just be a corrupted file or system error that could be fixed bya full wipe and fresh install or it could be like my friends and the usb could be on the way out
on the topic of usb ports i do think they could have been better designed and iam hoping mine doesnt break as its needed for hdmi out , charging , docks , etc etc
Thanks Buxz,
As a follow up, I put the battery back in after taking it our for about 3hrs and all seams fine. I know that it isn't a permanent fix but I think it points more to software than hardware, which in a way is more annoying as its all about trial and error, as you described. A mechanical fault is more straight forward.
I just dread having to charge it again!
Regards, Woolly.
UPDATE
Charged it overnight and no problems when disconnecting it this morning. So far!
If anything, the battery life it better than before the problems. The fact that removing the battery for 3hrs broke the cycle of connect/disconnect, makes me think its soft/firmware related.
Woolly.
Too bad that last thursday I used the charger from a kit similar to this (link found in the forum 3 months ago).
(h**p://w*w.befr.ebay.be/itm/Dock-Sync-Cradle-USB-Charger-For-Samsung-I9100-Galaxy-S2-II-Plug-/260876977248?pt=PDA_Accessories&hash=item3cbd7ac460), directly (without the cradle)
It was the first time I use the power adapter directly to recharge my phone.
And since thursday my phone detects unexpectedly usb connection (and says I ave to close all aplications to use with Kies etc...).
I suppose it is no coincidence and that this fu***** charger damaged a capacitor or another electronic component of this kind inside my phone!?
What do you think ?
What can I do? Send it using warranty? Disable USB detection (how?)?
Thanks a lot in advance for your help!
Edit: Now the phone is not recognized when I connect it to computer (usb) or it starts the car mode!!!
A lot of people have this. Try brushing the usb connector on the bottom of your phone using a CLEAN and DRY toothbrush.
I had this problem, this fixed it for me ever since. Also bending the connector a TINY bit to the middle of the hole may help. But watch out, as it's horribly thin.
Two connectors are bent because of your new charger, or dust is causing the problem.
Thanks for this first answer! But...
Three others things (I've cleaned the connector as you said to):
The screen lights up by itself, too! And 9 times out of 5 when I press the power button (in order to lock and switch off screen) the phone just freeze and the only way to get it back again is to remove/replace battery!
By the way the battery drains faster than usual!
Do you still think it's only a matter of dust/connector (just asking but strange coincidence...)!?
Hello I have exactly the same problem since 2 days first it started thinking its connected to the USB, second thing is it wakes up soon after you have put it down and if you press the power button it freezes I have tried it more than 50 times and it freezes every time (when its connected to the charger only froze once) and today when i try to connect it to the USB nothing happens.I have tried Hard Reset , restore to a stable setup with CWM but it wont help. This happened when I got home after I was 2 hours outside working and it was very cold and moist but I only had the phone outside my pocket for 1 - 2 minutes to make a call and some very tiny drops got on the screen.I regret taking it with me if I only knew that was going to happen. One other thing I had an App to track the battery state and now when the phone thinks its connected yo USB but its not the program says my battery is over voltaged. What happened with your phone . Can someone help
Hey all,
After being fine for almost 12 months, my phone has suddenly developed a bug. Nothing has changed over the last 24hrs, so I am not sure where it has come from.
It started with a notification saying 'activating USB will turn bluetooth off. Continue?'
There was nothing plugged in to the USB at the time, so I'm not sure why it came up.
I clicked 'NO' but it kept happening constantly until I reset the phone. Then when I turned the phone back on, the battery overheat sign came up. It clearly wasn't running hot, but it only went away after I removed the battery.
Then this morning after I unplugged my phone from the charger it said it was still on charge and the 'battery full' notification wouldn't go away. So I reset my phone, and again the overheat sign comes on. Take battery out.....etc.
Now it is telling me that it is on charge (it isn't) and that USB device notification.
Phone is running 2.3.6. Any ideas?
Possible USB port malfunction. Maybe try cleaning it.

Second that.Clean the port with a cotton bud and cleaning alcohol.
Is Metho ok to use?
I might look up how to take the phone apart and give the insides a proper clean, rather than just poking around the port.
I'll await an answer about the metho before I give it a crack.
Thanks for the replies.
You dont have to take the phone apart
Quite a few people have had problems with dirt in the USB port its caused problems similar to and exactly like yours.All they have done is gone to the chemist,or pharmasy or however its spelt and for a few bucks you can buy cleaning alcohol.It must be this kind because of its high alcohol level it drys quickly and doesnt leave moisture inside when done.A few gentle wipes and thats all it needs.Dont take the phone apart cos the port is closed and it will be of no use.Meth is heavy and will leave alot behind drowning the port again.
Hi. I accidently dropped my Galaxy s2 in water. But I immediately put it in rice and a day later the phone is perfect. I tested features sound, charging everything works. However, the problem is when I connect the device to my computer using a USB it charges the phone, however the computer doesn't recognize it. It says "USB not recognized" How could this be if my phone is being charged? How can I fix it?

I suggest you dry it some more and see if the issue gets resolved. If not, check your USB port to see if it needs cleaning (use a fine brush gently to remove dirt or other accumulations). If nothing else works, you may have to change the USB flex cable.
A day in rice isn't long enough. You need to shut the phone down & remove the battery immediately after being exposed to water (if it didn't auto shutdown) & put it in rice for a week. You've most likely caused permanent damage by using the phone a day after exposure.
If you're lucky a USB board/port change as Neo suggested may fix it, but don't be surprised if it doesn't (I still don't fathom how people drop phones in water).
I dropped my phone in the pool and it died. Completely dead. I also made the mistake of trying to switch it on. Two repair places said it was finished (not quite sure what these guys do, but it's not repair phones)
I dried it in rice and salt for a couple of days and it was still dead. So I took it apart, washed the motherboard in alcohol and it sort of came back to life, but wouldn't hold a charge or switch on, but was memory visible via the USB on the computer, leading me to believe the motherboard was "alive".
I took it apart again, washed the main board, charging port, dried and reassembled. It kept switching off when the screen was connected, so I disconnected the screen and charged the battery: Everything okay, can connect via usb, charge stable, LEDs doing their normal thing. I assumed the short was somewhere in the screen assembly, so changed this., I can now even boot in "recovery mode" and see the memory rather than the Hisuite thing. It even connected to to the car via bluetooth. It *even* started playing music which I suspect was a 911/112 waiting ring I must have dialled by accident since it has no SIM.
So the phone is "alive" the touch I'm guessing work, the display is brand new, light up but displays nothing.
I'm running out of ideas of how to wake up the display though and am thinking it might be a problem with the graphics card, although I don't know how to test this.
My priorities are:
Return the phone to it's state before being dropped (i.e. solve the issue with the screen)
Access data (n.b. I haven't got Hisuite installed or activated and it doesn't simply give me access to DCMI and contact which is what I care about)
Hard reset or similar to return the phone to function with data loss.
Change the motherboard (I don't really want to do this).
