I just bought a samsung galaxy Alpha with Epsil 4.4 rom installed and twrp and root installed so normally i would reset the phone and flash the stock firmware and mess with it for a little while but the thing is it won't connect to any pc at all
I've tried the following
5 different usb cable
putting it into different usb port
the *#0808#* code and messing around with it
Restarting
Factory reset
different pcs
Replacing the battery
giving it to the repairshop but they cannot fix it
Also I noticed that USB options are missing from the phone litterally missing from the phone it self even at the Developers option its missing. when you plug the phone in to a usb it just charges tapping the charging notification does nothing charging rates are also slow even using a 2A 5V charger it takes about 4~5 hrs even tried replacing the battery did nothing as well.
Can anyone help me is it a software related stuff or hardware related? TIA

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.

I hope this could work for you too
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
Hi.
I've been using my S3 for about 2 years. Recently, I started having the following issues with it's charging port:
1. Charging is not consistent. It varies a lot. Sometimes slow, sometimes fast. Original Samsung charger charges slowly, HTC one charges the fastest.
2. If battery drops to 0, it does not turn on by connecting the charger. Instead, I have to connect it to PC. It then turns on and then starts charging.
3. It is not recognized by my PC (or any PC) that used to recognize it before. Changing USB cables, reinstalling drivers and all the usual tricks don't work. It is not recognized in recovery mode or mass USB storage mount either. However, it still charges the phone.
I have a strong suspicion that the problem is with the port but I need confirmation from you guys before giving it for repair. I'm on a custom 4.3 ROM and changing ROMs didn't help any of the above issues either.
Thanks.

Sounds like it could be the port at fault. The original charger is hopeless and not a good guide to go on.
So as the title states. I am having problems with getting MTP options while plugged into a computer. It sometimes works and others doesn't but it seems to work once on a first try on a new system and then the next connection it is only charging.
I was thinking maybe faulty port or cord. As I have tried several cords which also work on other phones I ruled the cord out. The port I have tried unplugging and replugging several times with no success, also jiggling the cord a bit while plugged in. No luck. It just randomly works fine once in a blue moon and then does not.
I have made sure my phone was unlocked, switching options in USB configuration setting though not the notification option because it is not there while it is not working, USB debugging on/off, restarting the phone, simulating a battery removal reboot, installing windows drivers, removing the sim card.
The phone is rooted with a custom rom for marshmellow. Can't really reset it or flash it without a computer to my knowledge. Was considering trying out Nougat but with the current situation I am not really able. Any help, ideas or insight would be greatly appreciated!
Hello everyone,
I am having a problem with my phone for the past 6 months...
I own an S6 Edge and suddently stopped charging from usb ( not at all, it only charges at usb mode, sth like 200-400ma, when the charger is the official Samsung fast charger) plus any pc doesn't recognize my device (pops u a message like unknown device).
I didn't encounter any problem with the phone before those 6 months. I tried factory resets, dalvik cache wipes, safe mode also doesn't work, tried different charger-cable combination, plus I borrowed a new wall adapter and cable and still got the same results.
Is there anything else I can try except taking the phone apart and try replacing the usb module?
Thanks a lot !

Change the usb port I would say. Strange that the pc isn't recognising it though
