[Galaxy S II Q&A, Help & Troubleshooting] Benfran:
This problem has been so strange. From the begining every forum i checked, most of the people had similar issues like:

-Phone thinking it's charging when the cable it's not even connected

-Never being able to shut down the phone (always rebooting itself).

-Sometimes when rebooting that spurious battery icon with the thermometer appearing.

The wierdest thing about all these issues, is everywhere i looked people kept saying very different solutions that seemed to work for them. Some were software related, like recalibrating battery or doing a factory resest (it didn't work for me at all on GB). Others were suggesting hardware related solutions like cleaning with a toothbrush, alcohol or compressed air (i also tried those but nothing worked in GB).

As i said earlier, i was extremely surprised (and happy :) ) when i installed an ICS rom for the first time and saw that all these issues had completely disappeared.

As i said, this problem has been very strange, and i bet not even samsung has a clear idea of what's the real cause or how to fix it.

But if some people are still getting those problems , and they can't officially upgrade to ICS, i'd suggest them to install an ICS ROM right away, at least to give it a try.

I currently have this ROM http://xdaforums.com/showthread.php?t=1451346&highlight=battery+percentage

And everything is working perfectly fine on version 7.1 (except some FC crashes with the AOSP dialer and some awful menu coloring in some apps with the Vertumus theme, like Black letters on dark grey background). But the ROM is very stable.

Warranty replacements

Please note if you are in the EU: Based on Directive 1999/44/EC which EU country should have implemented by 2002 you have a right to a two year warranty on all consumer products.

They can exclude water damage of course, but at least in the first 6 months after purchase defects are assumed to have been present when the product was bought and the burden is on the seller to prove that you are the cause. This means they will have to prove that it was water damage, you don;t have to prove that it was not!

Also the 6 month term and the two year term are a minimum, some countries have longer terms for one or both!

Finally, the seller has to honor this warranty, not the manufacturer. During those two years the seller can not tell you to go to the manufacturer. The seller is responsible for handling everything!

I have the same issue, and i am going to fix it by myself:(

I would like to ask is it possible to recognize my current board's Rev without open up my phone? and how can i know which Rev I need? thanks for any help
[Galaxy S II Q&A, Help & Troubleshooting] RFC1795:
I think you should be safe just getting the rev2.2 board.
[Galaxy S II Q&A, Help & Troubleshooting] fenchai:
lol

That's only because you got your phone rooted, which is not a bad thing at all. Just get used to it, there are a lot of flash-able stuffs to make it dissapear but that is just a pain in the ass.
[Galaxy S II Q&A, Help & Troubleshooting] RFC1795:
Huh? My phone is rooted and it doesn't have that ... that only happened after I spilt water on it .. replacing the USB port for me solved the problem

I had similar issue + Grey bars, i flashed hydrogen ICS rom and both problems were solved
[Galaxy S II Q&A, Help & Troubleshooting] gani_d:
Solved

Finally this problem is SOLVED.

Charging problem and car mode activation problem starts because you may have tried forcefully to insert charger USB other way round and in turn the pin inside the phone USB slot has moved down.

SOLUTION:

Using hair pinner or using some other thin pin, move the pin inside the phone charger/USB slot up towards the screen and voila all problems are gone.

Does anyone have a problem with the connection itself, mine is really loose and if i just nudge the phone, the charger falls out of place?
[Galaxy S II Q&A, Help & Troubleshooting] RFC1795:
No, not at all .. it's quite a tight fit. I'm able to hang my phone from the cable while plugged in. Also just tried on the old port I had in there, that's also tight.

Either your cable or port to blame. Suggest trying someone else's charger, or phone on your cable.

Well, I'm one more with this problem.

It started about 4 days ago. Symptoms:

1. I started getting random beeps when the phone states it is charging, even if it isn't.

2. After a while it shows a message about stopping charge "Charging stopped. Voltage too high". I dismiss it with the OK button but it keeps showing up every 30-60 seconds.

3. Doing a Shutdown results in shutting down and then rebooting. It is not possible to stop doing this except by removing the battery.

4. As soon as the battery is reinserted, it boots even without pressing the power button.

Cleaning the port with an auto toothbrush helped and it stopped doing it for a day of so. Then it returned. Pushing the USB pin slightly upwards seemed to help for another day, but again, it returned.

I only charge the phone once a day, even with heavy usage (2700 mAH Momax/LG batt) and am usually very careful. It is possible (but unlikely) tha the USB port caught a few drops of water when I was drinking, but also unlikely.

I think this is a hardware issue on the port and reflashing/resetting is pointless. I kept moving the port with a pin and sometimes it worked for a bit, but it made it worse as it is now totally messed up - It will not charge at all.

I have been charging the battery in my girlfriend's SGS2 and ordered a port/board/ribbon from ebay (7 Eur, probably rev2.3). Should arrive in 3 days.

I suck at small electronic repairs, so it will be challenging to do it, but I'm armed with a few videos and the service manual. I might take photos of the repair and do a small tutorial here.

A tutorial on either how to fix an SGS2 bad port or break the phone up to a point you need to buy an SGS3. Maybe my spending demon is just making up excuses. :D
[Galaxy S II Q&A, Help & Troubleshooting] scayre32:
I had that problem and fixed it by cleaning out my micro USB port. I used a very flexible plastic toothpick from a Swiss army knife and spent half an hour teasing the fluff out. Be VERY gentle if you decide to try this.

i had the same problem, i just went to buy a replace part for the usb port for €7 and changed the part in 5 minutes. It's a small piece with the microphone and the usb port, some flex cables and thats it.. Everything working smooth again.

The quality of the usb port doesnt seem to be very good and moist and dirt damages it really quickly. I bought 2 more replaces just in case.

It's not worth sending to samsung service, change the part yourself.
[Galaxy S II Q&A, Help & Troubleshooting] jomo023:
Hi,

I had the same problem, and I change the usb port myself. My phone can charge now (I just tried 5 minutes), but the problem still there!!!!

When I unplugged the charger, the phone seems to be in charge, when i shut down, it restarts automatically, and the thermometer icon is appear.

What's wrong with the new usb port? It's a rev 2.2 like the old one.
[Galaxy S II Q&A, Help & Troubleshooting] MaRw1n:
hmmm

hm sad
[Galaxy S II Q&A, Help & Troubleshooting] Krautmaster:
Well i have the same problem by 100% - charging all day long and even if the phone is out is "charging" without any cable...

USB Port looks in perfect condition and i never had random connection problems within 1 year now...

I dont know if it could be software related, i tried out CM10 yesterday, worked fine but even on stock i have this problem.

Removed battery, removed Sim... still "loading". If i boot after battery out, it stays connected after one time plugging in USB.

:(
[Galaxy S II Q&A, Help & Troubleshooting] xpressman:
erm, my friend also faced this problem, maybe the water went into ur phone, cause short circuit? my friend phone recover by itself after few days. lol
[Galaxy S II Q&A, Help & Troubleshooting] Beowulf_pt:
I installed 2.3 but I also have a spare 2.2 board (that I have not used). My original board on the SGS2 was 2.2.

2.3 works perfectly. The biggest difference (visually) is the fact that the microphone is a lot different. Instead of a big plastic block, it is now a smaller metal piece. The port itself looks similar. If you look at photos on Ebay or other sources, you can clearly see the difference in the MIC, but I do not know if it was improved in any way.

My 2.3 is working perfectly, so I would recommend trying to get 2.3 instead (assuming it has any improvement) but if 2.2 is cheaper, just go for that.

Both boards cost about 6 Eur on Ebay, I see no reason to pay much more for it.

ive sent phone to samsung UK and they have said there is a major liquid damage to the usb port and they will charge £55 to get it fixed. said no and will do it myself. shame tho cos they dont accept explanation that its a hardware issue
[Galaxy S II Q&A, Help & Troubleshooting] Scratch0805:
I agree its a hardware fault, i've had my phone replaced twice so i'm now on my 3rd s2 in 2 months the new charger that came with my 3rd s2 has burnt out the same as the other 2 did only this time i was lucky enough to have the phone in my hand and managed to unplug it before it did any damage to the usb port. I now just use an external battery charger and have a spare battery so hopefully it shouldn't ever happen again. Its also happened to my 3 month old note twice and I'm waiting to send that back again as we speak.

I know for a fact that no water has touched my chargers or any of the phones i've had.....
[Galaxy S II Q&A, Help & Troubleshooting] pinkster:
A week ago I had to change the USB port again, for second time, in less than a year of usage. I was traveling so I went to a Samsung official repair service and they charged me 16€.

When they opened the phone it was the same as first time, the USB port was very rusty and with a lot of green sulphate.

Anyone knows the reason of this happening? Is the USB port really cheaply made and rusts very easily? I never had this problem with cheaper phones and same usage.
[Galaxy S II Q&A, Help & Troubleshooting] imlgl:
I replaced my board twice, both of them faulty. First one, got no signal, charging, speaker and microphone didn't work.

2nd one speaker and microphone didn't work.

Just hope the 3rd one will work okay, pretty sure it's not me as my original one works.

Fixed!

I wrote to Samsung on their local danish Facebook page. They told me to take out the battery for like 10-15 minutes and then put it back in.. And it worked with no further issues! Now my phone is back to normal! :cyclops:
[Galaxy S II Q&A, Help & Troubleshooting] energetixgsa:
i had that problem too. for me the problem was only software usb port is not the reason about this kind of problem, the voltage is choose by the software not from the hardware. i clean the port put out the battery all day long the phone was without battery, then i go to factory reset, and nothing, but in some forum one guy suggest this solution, type *#9900# then go to copy to sd card, and my problem is done at this time.

Just in case any one is still wondering about the difference between going from a REV 2.3 port to a REV 2.2. From what I can establish there isn't any. MIC, speaker and charger all work. Hope this helps people in the future.

I cant get a phone signal at all. Just wifi
[Galaxy S II Q&A, Help & Troubleshooting] FirebirdStud:
I'm on me second replacement USB port as well. This is a real problem! But, at 6$ a pop on eBay I guess I cant really be mad.

I've had REV 2.2 and 2.3 and no differences that I can see, other than the 2.2 came with the rubber piece over the microphone and two sided tape on the board in different places, the 2.3 had neither. :confused:

USB 3.0

I have no clue why it worked! I tried connecting usb to both XP and Windows 7 thinking that it may be a driver issue but it didn't worked. Then i searched and found an article for trying USB 3.0 port. Luckily i have 3.0 port in my PC and it worked!
[Galaxy S II Q&A, Help & Troubleshooting] Aircondition:
I've had the same problems, phone said it was charging itself even when cable was disconnected and the battery could go from fully charged to zero in a very short time. Lets say I had 50% battery left and then restart it, sometimes the battery could drop down to less than 10%. First I thought it gotta be the battery that is damaged but when I removed the battery and then plugged it and the battery level was restored to what It was before. If it wasn't the battery could it be the firmware? I've tried flashing stock kernel just to make sure it wasn't the firmware but the problems persisted. After that I found this thread and did as many of you've been saying, I took a toothbrush and then lifted the pin towards the screen and then problem fixed. I was close to send it in for repairs which I'm glad I didn't do.
[Galaxy S II Q&A, Help & Troubleshooting] brunomiiguel:
Which one is faulty? My charger or the phone usb port?

My GSII suddenly started to have problem with my charger, it only works when the "connector" is tilted in a specific way.

On the other end, the USB cable works perfectly, I can connect the phone to the computer, but it has problems when i use the charger. I've tried this:

But it didn't completely fixed the problem, it charges well if the phone is standing still, but the slightest touch on the cable will disconnect it for a second.

This phone is less then a month old, I'm really disappointed with the fragility of such an expensive gadget.

Hi, I read the whole thread in two days or less, I also read other threads about the issue, but I don't see anyone with the same problem as mine.

I went to my bathroom a put my phone near the sink, then I connect it to the charger, but the usb end of the charger was wet, I took it out but the phone behave normal, so I kinda dry the usb on both the phone and the charge and put it to charge it, I went to the shower and put so music on the phone, but the phone started to enter into the voice app (like if I was holding the home button) I went out and disconnect the charger off the wall and the phone died, I tried to turn it on but it only make it to the boot logo and power of, I took the battery out and put it in, the phone then went into download mode and stuck in there so I took the battery out again and then when I turn it on it marked low battery in a small red letters in the right up part of the display, so I connect it again to the charger and it chargered it normal. Long short story the phone only works when plugged into the charger, I pretty sure that the usb flex ribbon got **** up with the water in the usb connector on the charger, but I am not sure if replacing the usb board will fix it, I have already open the phone (I am a EE student, no biggie) and it very easy, but not even sure which part will work as I have read about signal issues with the same rev version (2.2) mine says something like:

i1900 R-B84

Rev. 2.2

Any advice would be very helpful,

many thanks in advance, and sorry if I am not very clear in my writting.

Hi everyone.

My S2 suddenly started to last 3-4 hours when it used to last at least 1 day. Tried to replace battery. Tried to replace firmware ICS JB, then kernel (siyah). Nothing worked.

I ordered a replacement part for the usb charging port. Replaced it. No change.

Sometimes it takes normal time to charge battery, sometimes it takes like 8 hours... any way it lasts 3-4 hours just by staying there "black", even when turned off. After such time it just drains completely. If I I take the battery off when it's 70%, I put it back then and it says 30%, it almost always gives me back half the battery. Which I find at least strange.

I have no exact clue what to do. How can I make diagnosis? Please help me! Where did I go wrong?

Same issue

I just started having the same issue, apparently it's a very common one. I called the service center and they told me they would reset my phone because that was the issue...for a fee of $50 :laugh::laugh: I did a full factory reset and changed my kernel and rom with no luck. I tried cleaning the port, I figured out if I unplugged my phone and it still had a charging icon, and then i bent the flat pin in the port down it would fix the issue temporarily, but now every time I unplug my phone from the charge I have to do this. Very annoying..

Hi guys. saw this thread in my sub list, and I remembered it suddenly. my charging port problem has been gone for awhile now so I totally forgot about it :)

Just a tip for those like me for whom the cleanup tips didn't work because the usb plug was too badly damaged or bent out of shape : you can find a replacement usb port, complete with pcb and connectors and all for less than 10 USD at a site called parts4repair.com -not wanting to do any advertising, i ain't related to them in any way. It's just the site I've found,that has the best deals on replacement parts for any smartphone. Shop wisely : I've seen the very same part go for 4 times this price (if not more) on some other sites...

Delivery took a little long by normal mail (about 10 days), but all the parts I'd ordered came in in tip-top shape, and replacing the pcb and usb port on a SGS2 is pretty trivial once you know what to do, it's just a matter of 2 connectors to disconnect and a little glue to rip away... In case of doubt scrounge the i9100 service manual around here and read it carefully, along with a 3$ set of samsung-specialized tool kit bought on the same site it's all that I needed : the replacement was done in about 30 mins (probly would've taken half that if I hadn't been lying on my bed at the time, and with a proper workplace ^^).

I took the occasion the entirely rebody my GS2 too, after 1yr 1/2 of bad beatings the plastic shellcase was pretty ill-looking, and the parts were only about 25$ all together... Now it's almost as brand-new (there just remains the screen-butning effect (but this bill is gonna be for the Orange service centre :p) and flashes like on the first day again. ;)

That I was able to follow very easily.

One thing to bear in mind.....there are 3 versions of this module....

rev 2.2, rev 2.3 and rev 2.4. You need to choose the right one otherwise you may find compatability issues. The "rev" version is printed on the circuit board.....very small printing....look carefully....
