S6 Edge, usb problem - Galaxy S6 Edge Q&A, Help & Troubleshooting

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

[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.

[Q] my galaxy s3 is not charging normally

hello ,
my phone is not charging normally.
sometimes i see USB charging while im charging it on AC.
i wiped my phone and tried installing a new ROM and a new kernel ( ARHD 15 and perseus kernel) still the problem exists !
After i unplug and replug , my phone can charge again ! but this problem happened to me 10 times and i still cant fix it !
any solutions ?
Hey buddy,....
I dont think so that is the probelm of your phone...
1. On wall charge , check whether its perfectly fits or not... (the same thing happend to me also)
2. Always use original Data cables... coz some of the data cables are made for low end device only.. they may not support USB charging..
Try to use Backside USB ports rather than Front USB s....
:good:

experts plz help me!

I am sure my problem is different from everyone here becuase i did alot of digging and cudnt find any solution to my problem. So my problem is that a month ago i got my samsung's original charger not working anymore, Which turned out that just adapter is faulty. so i bought an apple adapter for my s3, which worked quite well. But a few hours ago i found my samsung galaxy s3 not charging. i flashed my rom again, did factory restore, anything i cud do as a first aid. i did it. i checked my phone on my bros charger but still no success. and his charger is working fine with his mobile, I have noticed that it connects without taking a second when i restart phone in download mode. But doesnt plug in to my laptop aswell( But works when phone is in download mode).
Note: My personal charger is working fine on my bro's cell.
Thanks!!
Usual reply .
Its the cable or the usb port .
Change cable
Take to a service centre .
....
But it does connect in download mode but not in normal mode to laptop with the same cable.

Try a different charger on your phone, if that works your cable needs to be replace or charger with cable replaced, if a different charger does not work then your phones USB port is damaged and needs a service repair.
There are multiple micro connections so it may connect to your PC in download mode but if the connections that link the charger are not working it wont charge.
So try a deferent charger and a different USB cable if neither make the phone charge the USB port on the phone needs to be looked at by a technician to repair it.

Honor 7 PLK-UL00 and B341 Device not recognised and its only charging

Hello all,
Honor 7,
PLK-UL00
B341 and EMUI 4.0
Android 6.0
Im unable to use my phone as USB Mass storage device. When i connect my phone to PC sometimes im getting as USB device not recognized and sometimes im not. I tried different PCs and different cables. ITs ONLY CHARGING
tried cleaning the micro usb port, uninstalling and reinstalling drivers in Pcs but it didnt work.
I switched off my phone, removed mem card, reinserted it, swithced it on again, connected my phone to PC(in sleep mode)
phone is detected as storage device and got notification in notification panel to select as charge only/files mode/ photos mode.
After ejecting and removing cable again back to issue. No detection. OTG also not detected. No Data transfers are being made but its only charging( even through Car USB port)
Anybody facing USB not recognised problem ? i hope its software related.
could anyone let me know of solution.
Thanks.
I am also facing the same issue
I thought I was alone in this issue.
Basically, my problem is, the wall charging and USB connect are reversed. i.e., I connect my wall charger, its showing as USB mode and when I connect the cable to a PC, its showing as AC Charging. I tested with Ampere app and when I connect to AC Charger, it is drawing only around 300mA(like it would do if connected to USB) and its drawing around 1.5A(like it would do when connected to wall charger) when connected to USB PC.
I have been having this issue for quite sometime and recently, I had upgraded to Marshmallow through OTA upgrade. I thought atleast this upgrade would fix this issue but I am still facing the same issue. I even contacted the customer care and nothing useful advice other than restoring to factory settings was suggested(which I tried and didn't work).
I guess it should be some software issue but don't know what it is or how to fix it. Any inputs would be welcome.

Cannot be recognize in any PC

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
