Default Huge (recall-worthy) problem with the usb port. If you're having the "car mode" problem, look here!

Ok, I'm not sure how this hasn't blown up yet but this is a HUGE issue and in my opinion it should be getting way more coverage. If you're having these problems:

1. with your phone going into car mode randomly
2. always having speaker phone activated
3. randomly connecting to kies when it's not plugged in
4. randomly saying it's charging when it's not plugged in
5. freezing, getting really hot, then loosing about 25% charge

then you have a problem with your mini usb port. It is NOT a software problem. I've seen this happen to 3 sg2's including my own. I have been able to fix all of them by cleaning the port with rubbing alcohol. 2 of them unfortunately relapsed. I have no idea why or how this problem is so prevalent but it appears to be affecting A LOT of people. What can be done about this? It seems like it is faulty hardware and not an issue with people just being careless with the port. I hope this clears up some confusion that people have.

Strange, this being such a "HUGE" issue and bearing in mind that this is one of the premier worlwide forums for the Samsung Galaxy SII, that we haven't come across hundreds of postings and threads on this subject.

I've not had any trouble like this (touch wood)
However, I would say 99.99% of us DO have problems with connecting to Kies via USB, so perhaps there is something not quite right with the port's hardware, as no amount og uninstall/reinstall cures is. Perhaps we need to wait to see how the next release of Kies's drivers perform.

Having said this, not many of us have a problem connecting via Odin.

Since Flashing I barely use Kies but have never had too much of an issue with it.

I would not say its Huge, maybe you have an app or setting that is causing conflicts.

Some people like me got 2 usb cables in the box, however they are both different, one is 'the good one' which you use for connecting to PC and features the USB trident mark on both cable ends, and the other one seems to be for connecting to a car's stereo for calling while driving or something, simply connecting this 'bad' cable triggers all manner of chaos and it should be avoided, the micro end of this cable is of course a bit different but I'm not sure if it's doing damage to people's phones.
I fear that of the people who only got 1 cable in the box, many were shipped the wrong one.

Similar story to the HP (sic) problem above...

Shortly after I connected my phone to my car-kit, I got a puncture! I spoke to Samsung who blamed Goodyear - can you believe it?

I've noticed my phone has been unexpectedly on speaker phone, but assumed it was due to Custom Car Home not deactivating it. It also fails to turn wifi back on.

I'll keep an eye on it.

I've got the car mode problem and my home button is going to accuweather app of some sort, instead of actually going to 'home'.

Now my phone is locking up

I certainly have a massive issue with my 4 month old i9100.
It will randomly start making the "charger connected" sound and the display will wake up. There's no way to stop that, if I turn off the phone at that time it displays the battery warning triangle and won't turn back on - the only way to turn it back on is to connect a charger.
If I ignore the charger connected sound then after a while (variable) it will stop, but now in Device Doctor the battery health goes from "good" to "overvoltage". If I turn the phone off once again I get the battery temp warning triangle and can't turn it back on without a charger.
If I leave it on after the battery has discharged for a while (ranging anywhere from 30-60%) it will go back to "good" health and all is well for a while.

While the battery is "overvoltage" it drains incredibly fast.

I've tried:
-factory resetting the phone
-cleaning the connector carefully (seems to go away for a while then comes back)
-rooting the phone
-new battery, problem went away for a while but now it's back.

I think it is definitely a hardware fault with the micro USB connector.
I also have a mate with the same issue, and there's a few posts on the internet about the same.

This *is* a big deal, and I have a feeling more and more people will start reporting problems as their phones get a bit older (like I said mine is now 4 months old).


--> note it is saying "plugged in" even though it isn't...

wow. this is exactly the problem that I am facing for the last week. my first time at the forum too since I was getting desperate trying all the usual stuff like resorting to factory settings and the like.

thanks for the alcohol suggestion - any tips on how you 'adminitered' the alcohol solution into the mini usb port?

I got a similar bluescreen a couple of times. Its when I plug in my 32GB MicroSD card into my Toshiba Laptop using Windows XP. Windows 7 doesn't have that problem. After googling, found out it was to do with RealTek drivers that needs to be updated. In Windows 7 the update was automatic. Windows XP isn't and it was never ever updated.

Maybe its something to do with your drivers? Tried on other computers?

Cheers

I initially thought the problem is more to do with a malformed connector than it being coated with something imo, The 'other' usb cable that was made for the phone is different visibly across the top, there are no flat prongs on the top, it's all metal.

I've taken my phone apart enough times to hate the process, but I just took another look for everyone and I can't see any reason why the 'other' cable should behave differently, the inside roof of the multifunction jack is flat, there doesn't seem to be a reason why the phone could tell the difference between the 2 usbs, but somehow it does, either there's some hidden trick with that, or some extra/other information (or none) is coming through the 5 copper wires in the ends.

Maybe if someone wrote a free app specifically to freeze car mode without having to root, that would be great.

I have the exact same problems. It started just after I updated to Android 2.3.4 (from 2.3.3). I thought it was a software problem or an app problem, so I uninstalled some apps I recently put on, but 2 days later (this morning) it started all over again

My phone is a few months old now and never had any problems with it untill now...

Very annoying!

Yep I'm having many of the same problems too. Clearly there are quite a few people out there experiencing this. I've had my phone since the UK launch (whenever that was) and the problem only started a couple of weeks ago so it may well be that more and more people start getting it.

Have had this problem for a couple of weeks now. Rang vodafone today with gritted teeth. After them going through the whole "its a software problem.... might be water damage.... we can have a look if you send it to us" and refusing every part of that they eventually agreed to bring a new shell to my work tomorrow and take the old one away. They did offer to reimburse me for a PAYG vodafone phone if I bought one when they have my sgs2 but I dont want that!

Worked for me anyway, although this isnt a cure to the problem that seems to be gradually snowballing...

I wouldn't say the information is too inaccurate. The problems highlighted really does seem to do with the (over) sensitivity of the USB port. That said, I haven't had that problem.

Spurious Battery Temperature Warning

Have a look at the last post of this thread. Not sure how true, but it really might be the USB causing all the problems. Dirt, moisture, etc...

Of course its not a problem with design of the usb port, it happens when sth gets into USB port (shortcut)

If it happens often for this kind of USB port but not for others, then I suspect it is partially caused by design. Maybe its just too small and deep causing moisture and dirt to get trapped in there. The older USB design might not have the same issue.

Although that said, let me repeat again that I don't have the same problem (currently). Not sure why it only effects certain people.

Started having this problem a couple of days ago. Plug my phone into my charger and it MTP initializes and charges incredibly slow.

Also, don't seem to be able to get it to recognize that it's plugged into my computer.


And another problem, not sure if you guys are getting this too, but regardless of the charge I have on the phone I can't turn the phone on without it being plugged in.

Phone is only 3 months old, almost to the day. Really sucks.

I've had this problem twice in the passed 2 weeks. Had my phone since July. Fist time I got the charging icon coming on and off the the second time about a week later it was going into driving mode. Gonna keep my eye on it, if it happens again i'll be sending it back.

To build on the previous information, my phone now likes to think it is always plugged in unless I forcefully move the mini-usb around when i unplug it.

Also, I cannot get my computer to recognize the device any more, sigh.

Interesting.

I hear the problem is carrier-related. Must depend on some carriers that like to restrict 3rd party hardware being attached. The fact it's happening recently points to the 2.3.6 (or KK+) update. Of course, I could be 100% wrong, but maybe try downgrading to 2.3.5 or stock firmware and see if it solves it. Not helping my own case: I'm on 2.3.6 (custom rom) on Virgin Australia and it works fine!

Agree with ironass, it doesn't seem to be a HUGE issue.

I can tell you it is not carrier related. It seems to be hardware related. Its a HUGE issue for the people that have the problem. It effects quite a lot of people as I have seen a thread on XDA as well.
I first had the problem whilst using MIUI, I was ready to send it back so I reset everything put original firmware back on and it was fine after that. My first thoughts were that it was firmware or kernel related. It was fine for about a week then it happened again. This time I was on stock firmware so it can't be firmware or kernel.

Hellow, new user here

Got into my car just now and it switched to car mode of its own accord 'wow thats clever' I thought...

Now its going berserk and doing most of what a lot of people have mentioned. Kies says connected when its idle, switches to car mode, voice recognition setup runs. I also had an added effect of being stuck in my contacts, pressing the back softkey just sent it in circles.

The battery also dropped from 60% to 20% after a restart...

I've just popped the battery, blasted the USB mini port with an air duster and its currently charging off a USB cable connected to my laptop. So far so good, can do without this bullsh*t though to be honest.

On a side note I just noticed my laptop no longer sees the phone as an external HDD when attached. Definitely something not quite right about this.

My first thoughts were that it was firmware or kernel related. It was fine for about a week then it happened again. This time I was on stock firmware so it can't be firmware or kernel.
If it's hardware, that should be covered under warranty. A hardware issue would mean that someone who's making these things isn't doing a great job, since it works on some but not others. Or perhaps over-use of the usb port.
I heard that cleaning the usb port with a toothbrush fixes the problem :P

Cleaning the USB with a toothbrush didn't work for me, unfortunately. Will try a can of air, though. We'll see if that works. This really sucks.

Am getting the same problem just in the last 2 days.
Had the phone since new 6months ago.

Will not charge unless reset the phone. Computer doesnt recognise it anymore, but it did 3 days ago.
The battery App shows its "Over Voltage" also will show a higher battery %age, then drop 20% after phone has had a reboot or i unlock the home screen

USB port is clean. All 3 cables, (Computer, 240V, Car) have been tested and do the same thing, wont charge unless phone gets rebooted or battery removed/replaced.

Still under warranty, but all this talk doesnt mean anything unless Samsung are aware of the issue. Do we know that they know its an issue yet?

Cheers

Wish I had read this thread earlier and I would have been more cautious . Seems like I'm having all the problems described above. Just swapped my iphone 4 for a galaxy s2 earlier today and I've been struggling to get Kies to work alll night. The phone is roughly 2 months old and the previous owner never mentioned anything. Looks like I'll have to trace him up tommorow. Its running 2.3.5 UK Voda. I personally dont think its a software issue but cant vouch for it. New to the android scene

So far I've tried dipping my usb cable into a bottle of acetone(nail polish remover) and put it back into my phone with no luck. The cable is not the original which was supplied if that says anything.

The phone charges ok in the normal charger

Hi there!

First of all, this is my first post on androidforums.com, so, hi!

I have the exact. same. issue. Well, all of those issues combined. While speaking to the official Samsung dealer in Israel, I was told that a certain amount of phones left the Samsung factory with a problem that is known to Samsung. The problem was described by the dealer as a problem with the PCB part which connects to the USB. It's lacks some sort of coating and is extremely sensitive to humidity which causes it to become corrosive and finally short.

I don't know if it's just them trying to blame me for a faulty phone or if it is true. What I do know is that they will NOT repair the phone or replace it with another unit. FYI, I've had my SII for 3 weeks. I live in a dry climate, nothing every spilled on the phone or close to it.

I hope you and the rest of us find a solution to this.

This has now happened to my Brothers SGS2 as well now. His is worse than mine and the problem won't seem to go away. He will be sending it back this week.

Lolz84 dont get yourself duped and have a go at them.

Anyways I had a chat with the chap who I swapped with and he agreed to take it back. He had a chat with vodafone and they offered him a replacement for 29 and in return he gets a white handset instead of the black one thats damaged.

I also decided to call up Samsung to find out about the problem and they obviously denied knowing of such a problem. The customer support lad was friendly and asked me to reset my device (which I already done a few times). Knowing none of the remedies worked he asked for my post code and located the nearest service centre. The service center happened to be a Carphone warehouse shop and apparently all I have to do is walk in there with my receipt and phone. If sending is too much hassle then droppin in is a nice option. Also constantly referring to "Apple customer service" helped a lot.

Background info:
  • Carrier: Virgin AUS
  • Purchased November 2011
  • Charge via 240v plug everynight
  • Never treated the plug very nicely, sometimes the phone would be holding its own weight dangling from the usb cord (accidentally of course)
  • Unrooted
  • Couple of pretty, but possibly virus like apps like those GoLauncher/SMS/Etc.
  • Same issues as original poster. Sometimes driving mode would restart itself over and over, seconds inbetween making the phone unusable.
  • Difficult to replicate the problem.

Here is a movie of the phone doing as described. Don't really need the sound.

Symptoms as described. I am under warranty still, but I think if multiple people are having a similar problem it should be well documented and investigated.

I think this should be added to the sticky guide somewhere as a common fault.
Other forums see the same problem:

Touch wood, this hasnt happened to me, but it does indeed seem like an extremely common problem, which is almost certainly hardware related.

To me, this seems to be a loose connection fault at the handset's USB port.
Are most of you who have this problem frequently plugging the phone in and out? ie. to a car docking station, car charger, wall charger, PC USB cable etc?

I dont have a docking station in my car so that does not apply to me, but when I plug the phone to the PC cable, if I ever have to unplug/plug it back in, I always do it at the PC side rather than the handset to minimise wear on the GS2's USB port. So I only plug it in at the handset port at the start of my PC session, and take it out there when I'm done. (eg. due to the unreliability of Kies, I frequently have to disconnect/reconnect, so I always do this at the PC side)

I would wager if one of you was to open up your phone to the bones, the usb port connection to the board would be loose, or there would be some tenuous soldering points there.

Agreed, thanks for pointing it out. Will do it right now.

According to at least one afflicted member here, Samsung have acknowledged (at least to their dealers) that the issue is a badly-finished PCB. If it were simple wear-and-tear then my own would surely be suffering, as it's seven months old, charged daily and has been connected to a permanently-attached USB cable on my PC probably as many times.

Just bought a new SGS II last week and about a day or two ago it presented some problems mentioned here: MTP initializing every time, like it was connected to a USB port when its not; sometimes entering CAR MODE and switching back; locking up and restarting randomly. Sometimes the Clock screen is selected.
Seems very unlikely that humidity is the issue, the phone is a few days old, came in a sealed box and not had contact to water. Very annoying problem with the phone, I was getting worried due to few reports on the web, thanks a lot to the other users by sharing their experience. Im going to change this one at the store, lets see if I have more luck in the next one.

I had this problem, so i rooted my phone and i couldn't be happier. The phone is faster, cleaner and all the issues it used to have seems to have been caused by the telco's software. Anyhow, i rooted my phone over a month ago and it still is running peeeerfect. FYI that's all.

A phone should be built to work without the need to root or mess around with settings just so you can get use out of the thing.

Mine ran hot yesterday for no real reason. I played 2min of shoot the apple and it went very very hot. Just a couple of hours before the phone rebooted randomly.

Exact same problem here. Car mode comes on at the most inappropriate times. I'm pissed.

And another one. IIRC the issues started around Christmas time, possibly when I got the 2.3.4 update. Phone randomly enters Car mode, or (prior to the last hard reset), when I had 'agreed' to the Vlingo EULA, car mode would start up fully, and phone would ask 'what do I want to do'. It would turn itself on, irrespective of whether it was 'asleep' or 'off', causing battery loss - and once 'on', screen would stay on, regardless of other settings.
I've tried rooting my phone, and de-installing Voice Command, but phone still tries to enter 'car mode'.
Further, I've had one occasion so far when the USB card 'could not be read' - needless to say, the card itself was fine.

The issue is extremely irritating and effectively makes the phone useless, as it now won't hold a charge during the working day, and I can't take it to meetings if it won't behave itself.

Having just gone thro' a complete hard-reset, with only Titanium Backup re-loaded, I'll be trying the warranty route, as AFAIC the phone is not fit for purpose.

If anyone has any details of the 'known warrany issue' (as in docs from Samsung), would be good to share them.
cheers,
h.

Howdy all. I went through it all over the last few days and the fix literally yesterday with Samsung. It is a known fault with the USB Port. Not that they will call it a fault per say, but they will fix for free at a Samsung service depot in about an hour or so - I guess it actually takes their engineer 10 minutes.

It was thanks to the forum that I knew exactly what to go and say and ask for. There was a certain amount of denial mode initially until I pushed it a little and referred them to the Internet forums like this one, then the issue was acknowledged.

Fix for me was they replaced my actual USB Port and the internal connections that they said had coroded. The engineer admitted it was a common problem and any little bit of dirt, fluff, moisture could cause it. Good Luck.
