Hi, I'm having this issue with my Galaxy S6 (SM-G920F):
One day fast charging stopped working, but standard charge was working perfectly, OTG was working, Odin too. MTP wasn't working!
One day I plugged my phone at the wall, and it didn't show that it's charging, after some reboots it started charging well (not fast charging). Sometimes I have to wait 0% for charge it again, but if I use a PC instead of the wall adapter it works (sometimes not, but I just need to reboot it)! So I'm able to charge the phone only from a PC if the battery is not at 0%.
I checked if OTG and Odin are still working... MTP is not working, I can't event hear the USB plug-in sound from Windows, if I go in Odin mode, Windows says: "unknown USB device" and it won't work, I tried to reinstall drivers, but nothing.
So right now:
- Charging from the wall won't work well.
- Charging from a PC works better.
- Fast charging won't work.
- OTG is working.
- Odin is not working anymore.
- MTP is not working, PC doesn't find the mobile, I also can't hear the USB plug-in sound from Windows.
I tried different things: re-calibrate the battery, restore the stock firmware via Smart Switch, flash some ROMs... But nothing.
I can't understand why some days ago Odin and wall charging (not fast) were working but MTP wasn't, now none of thease are working.
The only thing that works well is OTG.
Right now I'm using OdexLite ROM with stock kernel, but I tried different ROMs, Samsung's stock included.
Hello
I have a same problem .
Please help.
check if in the setting there is an option: start manager, try to turn on MTP application.
SM-G920I with same trouble, tried on fedora linux

I tried unsuccessfully to make my Fedora 24 and Fedora 25 detect the device, also tried on a MacOSX. It just charges, not only doesn't detect on download mode, as it doesn't even detect normally for file transfer etc.
Could it be an automatic update that killed MTP and fast charging? I've been searching the web for three days already searching for an alternative to flash/root or whatever to try to downgrade it and see if works with older version, but I couldn't. The device is 2yo, but is as new, I changed the battery and the connecting board on authorized service also with no good results. I hope I can make it work again! I appreciate any insight the community could have on this issue.
Cheers!

I upgraded to Sky-ICS RC7.4 Speed yesterday and today. Obviously the USB mass storage was working earlier because I got the .zip file for the upgrade on the phone. Well, just a little while ago I tried to connect so I could pull those zip files off just to save some room and it won't connect.
I can charge the phone, the laptop(Windows 7) and the phone both make sound/vibrate when connected. BUT, with I go to "Connect storage to PC" it tells me to unplug the cable, which it hasn't before but I did it anyway. I unplug the cable press the connect button again it states to connect the cable, I do. Press the button to connect and I get the same result. I've tried enable USB debugging and try again and it states to disable, blah blah blah.
It's great that I can charge the phone via USB all day long but really sucky that I can't access any of my files via my laptop.
Anyone had this issue or know of any fixes that may alleviate this issue? I sure would appreciate your help.
FYI, USB drivers are installed on the laptop and reapplied after the the issue of not being able to connect USB mass storage...
update: I am able to see the two mounts in computer management on my Windows 7 machine but not able to access them through My Computer.
I was reading from other threads about a possible Windows issue, how I find it unlikely, but I did a system restore from an earlier date and that made no difference. It's still a matter of the phone connecting completely to the pc.
Also tried different ports and usb cables, no avail.
I could really use some input so that if need be I can access the files on the phone to either flash back to stock or at least modify the files I have on there now to let me be able to attach my mass storage. I'm liking the the rom it's just a few little things like this that are making me completely love it.
i have the same issue if i plug in to the front usb ports. no problems with the back and its only been since i updated to seans latest speed stripped ICS rom
I was having the same issues. I turned the phone off, took the battery out, and then restarted it. It worked.

Correct; you need to reboot your phone because you probably connected / disconnected too fast and the phone is bugged out now.
I'm on 7.4 speed stripped and its working fine for me. Did you try installing the Samsung USB drivers exe in the dev forum?

Recently we have been getting in stock i997's that are having USB issues connecting to the computer. As always we enable USB debugger and connect to the computer however now the units are going into charge mode a few seconds after connecting to the computer and shutting the device down. Once we disconnect the device from the computer it automatically restarts.
Here is what we have done so far with no luck:
-Enable USB debugging
-Disable USB debugging & enable mass storage
-*#7284# was set to USB=PDA, changed to Modem & back to PDA
-*#9090# Didn't see any relevant options
-Slightly bending the USB port
I don't think it is a hardware issue but a software issue that needs to be configured. Any help would be very much appreciated!!
USB
Get it as stock as you can with software. If the USB still does not connect correctly then it is a hardware issue. There was never a problem in any stock rom with USB connectivity.
Just my thoughts. It may not be the phone but the connection-- Computer, cable, oops,-- or drivers.
I'm facing the same problem !
I too have the same problem very weird tried several time stock have no issue in connection. this issue occur after few days not immediately and no regular pattern so can't say what's going on. right now my phone while put on charge shows charging but when un plug it still have 1% as charge no battery put to charge message shows up, tried with charger, usb to computer.
I also noticed before that charging stops and only come in effect when you pull the battery and plug the cable put the battery it will start the phone automatically and charge start up.
Can't ever put in charge in switch off mode as every time it automatically switch on my phone.
I tried several time these step 1. Go back to stock by heimdall , 2. heimdall kernal flash for red cwm, 3 wipe, format, fix permission 4. flash
couple of days work smoothly then problem reoccurs
Did you try mtp mode like with media player mode

Thanks RDomke for the reply.
We already flashed UCKD5 with no luck. Would there be anything else we could do? I agree that it may be hardware if stock doesn't work but we have been getting in too many units out of box with this issue. Not saying that it isn't possible to be hardware, just seems like it's something that could be software related.
SOLVED

RDomke,
Many thanks as we have solved the issue with your advise. The 1st unit we were testing did in fact have a bad usb port. Once properly diagnosed we tested another by flashing it back to stock and then performing a factory reset. Once done issue was solved and worked on many other with same issue.
Hello everyone.
I am having issues with my Note being detected by my PC, I have installed Kies 3 and when the Note is connected the connection process starts but fails ( I tried using camera mode instead of MTP and Kies says It must be MTP so something is connecting), Also the device is detected in the device manager of the PC and the Note itself says its connected by USB 3.0.
I have updated, un-installed re-installed, all the drivers and Kies. I have also used a standar USB 2 cable and most of the ports on my PC.
Does anyone know what's going on? could it be a USB 3 issue with Windows?
Any help would be appreciated.
Cheers

I've been having consistent issues connecting with the tablet through adb, on both linux (2 separate installs), and windows 8.1. Sometimes it just will not detect it. It gets detected as mtp storage fine, but adb devices returns nothing. Ill triple check all the relevant settings, make sure the computer has been authorized by the tablet etc. It will literally work just fine, and then 10 minutes later without even disconnecting the cable to using the tablet, it will no longer be detectable by adb.
I'm hoping it's just bugs in the release firmware that haven't been ironed out yet, and will disappear with future upgrades or with the flashing of a custom rom.
I've also had it refuse to charge through my laptops USB ports, even the special "faster charging" port.
It turns out my issue was the unit itself I took it back to JB-HiFi and the staff checked it out and it wouldn't connect to any of their PCs, we tried the Demo unit and it worked fine, So i exchanged it and it works perfectly..
Thanks for your reply though
Cheers

I have a MTCD head unit MX (witson) with Android 5.1, my problem is that the USB port cannot recognize my phones, A note 4 with Android 6.0 (eRobot ROM) and a Samsung GT386T no rooted with stock ROM 4.4.2. The USB port works find with a usb stick, I can play music, pictures, etc. but not my phones. Both have the USB debugging enable.
When I plug a phone it is charging but nothing happens, my note 4 after a few minutes pop a windows saying that there is a problem with the connection MTP and that I need to download samsung Sync etc.
What I want to do is to use the mirror link function.
Any of you know something about this issue?
Thanks in advance for your help.

I believe i read that there is a specific app that you have to run on these to do the mirror link...easy connect, maybe? Did your HU come with an instruction booklet? I was looking through mine earlier and it went over in detail how to setup mirroring through that app.
Yes, when I tried to use EasyConnected is when I saw the problem. The app waits for my phone to be connected, It says that it must be turned on USB debugging, but it is on. Then I checked in the File manager and the USB was not enable there, like if nothing is plug it. If I plug a USB memory it works fine.
I will try today to do a factory reset.
Thank you!

You ever get this solved? My easyconnected never stays connected. WiFi and USB both are garbage.
WiFi randomly disconnects.
USB also disconnects asks me to allow USB debugging every couple of minutes. The phone never remembers the headunit, so it constantly asks me again to allow connection. Must be a crap RSA fingerprint coming from the headunit.

Nope, Still does not work for me. Same symptoms as you. I already tried with 3 differents phones, factory reset and different versions of easyconnected.
I seem to have USB connection working now with only one "allow USB Debugging?" popup, only when I first connect.
What I did was turn wifi off on the headunit. I am not sure why it worked, but I just wanted to turn everything not needed off, and see if the headunit would stop disconnecting all the time. So far so good. I can probably live with one annoying popup, instead of one every few minutes.
Of course you have to keep the screen on the phone on, and the battery in the phone will deplete faster than the headunit charges it, but still an improvement. I had a 30 minute drive today, and the USB never disconnected!

paniqueado, try the da_anton ROM. I just installed it and easyconnect finally works as it should. I just plug in my phone to the USB and it fires right up! One prompt if any on the head unit, and NO disconnects whatsoever.
