[Q] Problem with USB port and function - Galaxy S II Q&A, Help & Troubleshooting

Today i found out my SGS2 have problems charging the phone, not only that. i also have problems with USB file mode, and keis mode. and if the phone is turned off. i only once got it to charge without booting. else when i connect the USB it boot the OS.
What weird thing is, that ODIN works without problem every time!
The problem appeared after upgraded to Darky Rom KG6 with jkay mod. but don´t think it has anything to do with that.
I reflashed to a Stock KG6 (still same problem)
From OS restore to default, and format (still same problem)
tried to flash back to KE2 stock. an but on CWM, and clear battery stat, and system cache.
flashed backup with a KE2 Kernel (still had the same problem)
What i found out is that, when i disconnected the wall plug charger, the phone still was in a state of charging. and it don´t give the sound notify when attaching the USB. but when touch the USB cable it suddenly charge and give the sound. but it can also go in MTP mode. or start Voice recognize.
Could the be a faulty USB port on the phone, or can Battery State and kernel updates have something to do with this problem?

im now pretty sure this has something to do with the USB port. when i just spoke on the phone. it suddenly began to change between Car mode a normal.
i than tried an alternative why to deal with the problem. I tried with a hairdryer after taken out the battery, sim and sd card, and carefully heat the back of the phone.
for 5 hour there has not been any problem. both the desk dock, and wall charger is working.
got a dejavu from the xbox days and RROD.

I have the same issue. I think the USB port is faulty.
The phone reacts to different electrical resistor values on some pins of usb port that triggers car mode, desk mode, etc. So, somthing is faulty in the usb board that reports to the system that has something connected to it: charger, car dock, desk dock, usb jig, etc.
I can't find any solution on the forum, I tried with several roms and got nothing.
So... I'm waiting for a USB Jig to reset counter, back to stock rom and send it back to store for warranty

My problem seems to be fixed by using the hairdryer on the usb port. I think the problem appear from the why you hold the phone and if your hånd become sweaty. Because there are nothing to protection the usb port like the sgs1.

[Q] VIII., dedung

HI guys,
i have 2 problems from 3 days:
i have a problem with my SG2 when i disconnect the charge cable my phone continually stay in charge and every 10-15 second say me charging paused voltage too high.
second problem is USB , when i connect my phone to my computer it does not recognize it .
3 days ago all work perfectly now i try to restore stock firmare, full wipe but the problem persists anyone can help me? thanks
Sounds like the USB circuitry issue we see a fair bit of on here. Given you've already done a wipe & gone back to stock & you're still seeing the problem, I'd say it's a repair job.
Edit to add - You could try gently cleaning the USB port with an new/unused toothbrush before you do send it in for servicing.
maybe is hardware problem i dont know But the problem is in the same spot may be the cable entry which is damaged
Yep it could be the socket itself is damaged rather than the board. I guess they only way you'll know (assuming cleaning it doesn't work; which it probably won't) is if you have a mobile tech take a look at it.
The cable itself can become worn on the pins from multiple flashing and removal of usb cable .

USB cable connection not working!

Hello, i am new to xda-developers, so please have patience with me
I was using my original usb cable to charge my phone from my laptop. But one day some strange things started to happen, when my phone's battery was completely depleted i connected the usb and phone started turning on and off very often and I wasn't able to charge it even a bit. When connected to wall socket charger everything seems to be fine, it's charging.
But now the usb is not working, neither computer sees it (before i used it), i used other cables, no good. Now it's original ginderbread ROM, maybe i should reinstall it, but i can't do anything since usb is not working in any way.
Maybe someone of you had similar problems and know how to solve it?
Thanks in advance!

Thanks for the quick reply!
I tried cleaning it with Tooth Brush and even used special liquid for cleaning electronics contacts and corrosion removal, everything seems to be clean. But still nothing happens when connecting to laptop.
P.S. Same cable is working when charging from wall socket charger, so it seems the contacts must be clean and intact (at least power supply contacts), so maybe it should charge from laptop?
P.S.S. I forgot to mention, when the phone's battery is depleted, when i connect to laptop, it doesn't charge but in time phone becomes hot. So maybe this would prove it's a hardware problem?
Try different laptop USB port. If this doesnt help than probably your data cable is faulty. Just replace it with another one.
I think Your phone is fully operational if AC charging without any problems.

I have already tried different laptop ports, even different laptops, already tried with different cables (which all functioning properly with other devices and all are marked U2). I am pretty sure that's not connection / cable problem.

[Q] S3 charges only in Download Mode

Hello XDA
This is the first Q I have I managed to work my problems off by myself to this point. Straight to the matter at hand:
My S3 stoped to charge normally on:
Wall socket solid cable charger
Wall socket usb cable charger
USB plug to a PC
External battery
On a turned off device it only shows the loading battery no charging
On a turned on device in normal boot it shows charging but no charge is applied (checked with various software)
It only charges in Download mode (slowlly due to the fact of a turned on screen)
I tried diffrent chargers, cables even batteries nothing really helps
Also its not being recognized by the PC when plugged in in normal boot but it's being discovered in Download Mode.
I was able to flash Stock Rom by ODIN but it also didnt produce a solution.
The only thing that comes to mind is to flash with a repartition but i cannot find the proper *.pit file and I don't want to do this before consulting the community.
I can reset the counter and send it to the service but I think that this is a software issue not a HW one.
Can anyone offer some assistance?
UPDATE:
The device when booted normally and pluged into "holds the charge" it dosent go up but it doesnt go down.
Pretty fun !
I think it's an issue with your kernel. Have you flash your device with a custom ROM and/or kernel ?
Well I was running PAC Rom for S3 at the time so the Kernel was based from that.
After that I Changed to XXEMA2 CodecROM 1053 Black Edition with Siyah Kernel still same outcome... And after that returned to the roots with Stock ROM with Stock Kernel
I have the exact same problem on my Galaxy S III for Sprint (SPH-L710). Did you ever find a fix for this???
Same Problem

I have the same problem too.
Did anyone ever fix it?
The phone charges when in recovery/download mode, pulling 300 mA from PSU, but only 60mA when connected and turned on.
Im using a normal usb cable, and have short the D+ & D- Pins.
I've charged the battery in a third party battery charger and that works fine, I also have a wireless charger that too pulls around 60 mA
Maybe you all need to change the USB connector module at the bottom of the phone? I've seen these break or do strange things in many phones including Samsungs. Not sure if they eventually get broken due to overheating or what the issue is, but that would be my guess.
i have a pb in my i9300i my cell going to downloading mode automaticaly

[Q] My S3 is not charging

Like a week ago my S3 9300 was taking longer and longer to charge now it won't charge at all, now is always stuck at 0% if i turn it off it will charge but very very slowly, i don't know if it's the phone or the battery maybe someone here had the same problem and could help me out a little, btw i have it with CM 10.1 thank you

Had the same exact problem with my i9300, got it out of warranty repairs yesterday. Was using a custom rom, but the same thing happened when I finally managed to flash it back to stock (had to manually press the microusb-cable as hard as I could into the phone all the time in order to get the phone recognized while Odin was working, was the longest flash ever lol..).
Remember reading about cold solder joints etc before sending it off, so if your phone is out of warranty for some reason you could replace the charging port yourself. Replacement part costs ~5$ (eBay) and if you got the skills it shouldn't be too hard to replace.
EDIT: Actually mine didn't even charge when power off, so I was pretty certain it was a bad solder joint or some other physical problem.. Have you tried cleaning the usb port with pressured air or just blowing into the port? Could be some pins of the usb port blocked with debris. Also check your usb cables, there are those with 5 pins and those with only 4. Saw the difference in charging speed while the thing was still working.

Well actually when i plug the phone into the PC it will recognize it and i can access the files in the SD card and Internal Memory and everything at the moment it's turned off and it's charging.
I have the problem that the phone only want to charge with soms chargers.
I can connect the phone to the original charger or to a pc or any device without problems, the phone will charge.
Even with an old blackberry charger (only 2 wires, no data) and car charger can i charge without any problem!
But when i connect the phone to the htc charger of my old phone, or to an iphone charger i see the phone is connected but it won't charge.
When i open batterymonitor i see that the charger is connected, but the phone still use his battery.
I tried this with all kinds of charders and all kinds of micro usb cables. Then i thaught there was maybe a resistor or chip or something build in some chargers, because i couls only charge with chargers with 2 wire cables.
Then i took a usb extension cable and i disconnected the two data wires so only the + and - 5V cables were left,
but still no success. If anybody knows where the problem is, please let my know
with kind regards! Martijn

Micro USB port problem

Hi.
I left phone with charger plugged in and went shopping.
When I came back to my crib I found out that phone didn't charge at all.
I found it strange, so I plugged the other charger, but it didn't work as well.
Then I plugged the other phone into the chargers. Both worked well.
I tried to plug USB into PC and it didn't work either. I made a factory reset and tried all steps again, but still no result.
It looks like USB port died itself...everything in port looks good, nothing broken or moving inside of it.
I wouldn't mind if I could reapply my drm keys, so I could update OTA Lollipop or Install ftf. I could just charge phone by magnetic port. But now I'm stuck with nothing.
What to do?
Hello,
Tried one other USB cable ?
If not OK with other USB cable, you can try installing Flashtool and drivers for your phone, power OFF phone and connect it in fastboot mode or the other (I don't remember the name) to see if the USB are really dead. No reset needed for that and this test call the 1 level hardware of the phone.
Mine not working aswell. The port seem to be loosen and only certain angle my pc would detect it. After a month of trying to get the right angle i think it broke. Went to my local phone shop they recommend me to have sony replace the usb port. Its gonna cost me so for now im using magnetic charger. Tried open it up to see if anything i could do but the port is tight sealed so im guessing a visit to Sony service center is inevitable.
