i9300 USB Port Issue? - Galaxy S III Q&A, Help & Troubleshooting

G'day guys
On Sunday I noticed my SIII making random noises but nothing was ever on the screen when I checked. While playing with it, it made the noise again and I noticed the driving mode icon appear in the notification bar for a second. I decided to update to the latest version of Omega 9 to see if that would fix the issue. Did the usual, backup, wipe, flash - all good. Omega 9 was running fine but my phone did continue to make the noise randomly. Ignoring it and continuing on my day I plugged my SIII in to charge while playing music, I picked it up like an hour later and realised that the battery life had gone down rather than charge. Naturally I started plugging it into all the micro USB cables I could find, connected to the power adapter, connected to my PC, connected to my car charger, nothing would connect and give it a charge properly! I managed to get 1 cable to connect for a second but then it would just disconnect. While I was trying to get it to charge it was randomly displaying the message that appears when you connect a USB OTG cable too, 'USB connector connected' - or something a long those lines.
I pulled the battery out of my phone, let it sit for a bit, inserted the battery and it started charging fine. I powered it on and it booted up with the TW launcher (I normally use Apex) and a grey box in the lower left hand corner of the screen that said "Safe Mode". I was just thinking, WTF (should have taken a screen), rebooted my phone and it has since gone back to normal.
It is yet to make any random noises or refuse to charge as of today (Tuesday). I got a bit worried for a bit there as I was dreading having to take it all back to stock and send off for warranty plus the USB port in my cousins SGSII died for about a month and randomly sprang back to life.
If it happens again I will be looking at a warranty as soon as possible. It puzzle me though, I wonder if the cheapo USB OTG cable I purchased off ebay could have damaged the port at all, everything seems fine now though. Has anyone else had any troubles with their USB connection?
Notes* My phone is in perfect condition, no liquid damage or anything.

Sounds like it had a software glitch. Check if it appears again and report here, but you should be fine in most cases.
Btw: Pseudo-Dead (disabled) USB-ports can usually be revived by powering off the phone and inserting a Jig. At least that's how I revived my brother's old Galaxy Ace several times already

[Q] Problem with USB port and function

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.

Did you really fixed just cleaning?
Yes it happening two times and it fixed it both times. So there is a pattern
hey guys... I posted something that worked for me...

I hope this could work for you too

Be careful of some wall chargers

Hi, not sure if this is specific to my HTC Sensation 4G (rooted), but standard T-Mo issue ICS 4.0.3), or more generalized, so I'll post this here. I have had no trouble connecting my phone via USB to my PC for charging, nor the car adapter, nor the AC to DC cable that came with the phone. However today, I attempted to put the phone with another wall adapter with a USB cable slot, so I can charge it in another room, as I have a spare USB to micro cable. Once I plugged the phone in, it started cycling thru all kinds of screen real fast, like email, messages, phone log, music player, then started playing a music track on it's own. I went to get control of the screen, but seems it pretty much froze. So I had to remove the battery and put it back in. Fine till I plugged it in to confirm it wasn't the phone itself. Soon as I plugged it in, started doing the same thing as before. So I again did the battery thing, and plugged it into my PC, and all is fine again. Just strange, guess the idea here is to watch your device when you use a new cable and/or charging system to make sure the phone doesn't go wild like it did for me. Again, can't tell you if just my brand and model, or this is general with more makes and models, so be aware.

S2 says its in download mode...when plugged into AC?

Just replaced the usb port/flex cable for the 2nd time on this phone, Galaxy S2 i777. First time was end of summer/beginning of fall, after dealing with an increasingly faulty usb port and charging behavior, this time it went in a matter a matter of hours, and the port wasn't dirty or corroded.
Charging was normal for at least a half hour but then the phone started thinking it was docked and going into daydream when plugged into a computer, and a couple times it went into download mode, once while plugged into AC power. USB debugging was also disable prior to the 2nd unexpected download mode. It also said something like "erased" something on the download mode, and said it was was stock Samsung firmware. I'm on PACman rom 4.2.2/CM 10.1 which I had just flashed about 2 days ago, previously Shostock 3, 4.1.2. The phone will automatically boot up when plugged in. It will also go into car mode like its docked.
Is this yet another faulty USB port, going bad less than an hour after installing? This was a good flex cable too, with the proper antenna for the i777... any thoughts or ideas?

Sudden trouble with USB port and fast-charging

All of a sudden the USB port on my one year old V10 is having issues:
Won't "fast-charge" when plugged in to LG fast-charger. But does do and show that it is "regular" slow charging.
When unplugged, status bar battery icon still showing charging animation.
Does not switch (or give option to switch) to data when USB is plugged into computer nor does it appear as device on computer as it did before.
Battery is draining very fast, probably 2-3 times as fast as it should.
Also doing the following, don't know if related to USB issue:
When I power off completely, before, I had to press and hold down power button to power back on, and would also get a quick vibrate.
Now when phone is off, just quickly tapping power button for split second powers on phone and get no vibrate. Also when phone is off, plugging in charging cable powers on phone.
These issues just appeared out of the blue yesterday. Nothing has happened to phone - not dropped, exposed to moisture, didn't install any new apps, flash a rom, nothing new done to phone. It just started happening. :crying:
I would say that this is being caused by one of 2 things:
1. Bad charging adapter and/or cable. Either use another charger/cable, or buy an original LG fast charger replacement from somewhere like Amazon. 3rd-party stuff may or may not work out well, I would stick with LG if you want to play it safe.
2. The actual charging port on the phone is bad. In this case, no charger/cable will fix it. This will probably mean buying a new phone, unless you have warranty/insurance, the cost of getting it repaired won't be justifiable.
So far one of my 2 LG cables have gone bad, developed a split in the wire, now it charges my phone sometimes, but sometimes not. And it rarely works for copying files to/from PC. My other cable works fine for the most part.

I have 2 OEM LG Fast Charge 2.0 cable and brick sets, the one it originally came with plus another one I bought. I also have a second OEM battery and LG battery cradle. I've tried all these plus others I have and all get the same result.
I mostly use the cradle to keep the second battery charged and swap them out as needed each day, so I don't actually do much charging on the phone. I also use SambaDroid to move files to a PC, so the only real problem this is causing is rapid battery drain. I'm no expert but I'm guessing there's a pin in the USB port that is shorting somehow and that it's causing the battery to drain. Any hardware experts out there? I need this phone to last another year so am willing to try minor surgery if it would help and if I can find a good guide to follow.
Edit: SambaDroid not working in Marshmallow. I also sometimes just take out the SD card and pop it in a card reader.

Has anyone successfully recovered from the sudden no charging/USB connection issue?

I'm wondering if anyone has suffered with and recovered from the sudden case of no charging/USB>PC recognition?
I've seen countless similar stories across the web, covering many of the Z Family. Some were simple reset jobbies, and I've seen as in-depth as what I'm assuming is an IC being removed, flux cleaned and re-applied (w ww .you tube. com/watch?v=ZyCeNfc99a0).
I purchased a new charger port and also a new battery, as I figured with all the insane constant burning of my pocket, it could use a new one. I'd hoped it was just a charger port issue, but much to my dismay, the issue still persists after fitting them.
I've tried every single button combination "fix", and all to no avail. Multiple leads, charger units, all that polava. Checked and cleaned connections with isopropyl alcohol, checked for burned-out looking mainboard components, at least those that are visible.
I was having minor inconsistent charging issues for a while, up until last Friday. I figured it was the USB port on the phone or the leads, and put it down to general wear and tear.
Last Friday I was at my mates house with super low battery, popped it on charge round his and I noticed it had died completely and kept boot cycling, like the charger was being plugged in and taken out over and over.
I took it out and tried it when I got home with the regular charger, and nothing. My phone is otherwise in mint condition and has been looked after since day one release in the UK.
I'm wondering if some super helpful person here would possibly have some other alternatives that haven't been mentioned, whether a hardware bypass or some trick that isn't amidst the countless cries for help out there.
Many thanks in advance.
Hello,
I have a problem when connecting to a charger it will go in strange charging mode that actually does not charge. It makes the sound like a charger is connected, no charging animation on battery though...
The problem for me it was the USB cable used for charging (i have changed 5 of them in 1 and a half years). Also same behavior happens when using a under 1A wall charger.
P.S. : The USB cables that i have changed they still work fine with other devices/phones .... but not with my Z5C. I`m not sure what but is definetly something wrong withe phone usb port (and it is not dirt).
no, but
I cannot get a usable USB connection to my computer, but if I hold Volume Up while connecting the USB cable to the computer, the charger LED turns red for a moment, then blue. It WILL charge in this mode, which I think is fastboot mode. Someone said it bypasses the charge circuitry or software, which makes me think that maybe I could go into developer mode and turn on OEM unlocking to see if I can stop it from trying to optimize charging. I also have not tried all the USB connection modes yet.
I tried to charge with this blue light technique on the wall charger, but that did not work. Just ran the battery down again and I could not boot the phone.
I know if I press Volume Down while connecting the USB cable to my computer that the charger LED turns green, but I am not sure it will charge in that mode. I think this is for flashing or something, but since my computer does not recognize the USB device no matter what I do, I don't think flashing is an option.
Oh, and when I do charge the phone with the blue light special (old obscure USA discount retailer reference), for some reason the charger LED flashes white every 4 to 5 seconds, but it seems to keep enough charge to get me through at least the day until I can charge again by same method.
Maybe we can keep pooling info here. I got the blue light technique from someone else on this site, so there are people here who know quite a bit about this phone, thankfully.
Well, I had that issue, too (at least it sounds pretty familiar).

Does your phone also believe to be connected to "something" all the time?
I fear there is some IC fried, although I never dared to open my phone.
My "solution" was to talk my local salesman into giving me a (used, but working) replacement phone, and I did not want him to find any traces of DIY
So, no, I never found a technical solution, probably they just scrapped my phone for spare parts, idk.
The root cause for my error (probably) was a faulty charger, therefore I am pretty sure I fried something hardware-like, but depending on your cause, ymmv.
Anyway, trying to clean your USB port, re-soldering the connector and/or replacing the battery sounds like being worth a try, anyway.
// edit: "cat /sys/class/power_supply/usb/present" used to always output 1, even when not connected. On my now-good Z5C this works like it should (connected ->1, not connected -> 0)
Hey people. I have tried all the tricks for several days. Tried several charging cables. Nothing worked for me. I just brought a new phone, and it came with a cheapo charging cable. Decided to plug it into my Xperia and it worked. Maybe a little fairy fixed my phone when I was out buying a new one. Anyway, I'm love my Xperia Z5. Using it right now. Good luck people
