USB connector - OTG and pc mass storage not working. - Samsung Galaxy S8 Questions and Answers

I've had my S8 for about 8 months now, pretty happy with the phone. Let me preface this and say I was with Verizon when I got this phone, a few months ago I decided to cut ties and go with Straight Talk as the service was less expensive. Over the last few weeks I have had trouble with the USB mass storage and OTG adapter not working at all, I am using the OEM pieces that came the phone. I go to plug in the cable or the OTG and my phone starts doing the USB connect/disconnect notification. At this point I am thinking of calling Samsung to see if I can get the port repaired under warranty, I think its weird that the OTG and cable are not working to transfer files or connect devices other than the charger. I have reset the settings on the phone, installed Samsung's mobile device driver on my pc (WIN 7 Ultimate x64) , no luck. Anybody run into this issue?

try another pc or get charging port repaired if it ain't charging properly

Called Samsung, they are having me take it to a UBreakiFix place for their technicians to look at it. They think it could be corrupt software or damaged charging port. It's still under warranty so hopefully they can fix it without having to refurb the phone.

Got it fixed, replaced the port. Phone had a small corner crack in the screen they said Samsung wouldn't warranty the port. Gonna call them about that.

[Q] usb cable problems

my windows 7 64 bit computer wont connect to the phone. spent 3 hours doing everything and it always gives me unknown device and driver install failed. The only thing i have not tried is to plug it into the back USB ports as sugested in another thread,I am at work now, but I also have 3 different micro usb cables in front of me and only the one that came with the phone works on one of the front usb ports and in the rear ports on my work XP computer. is there something special about the samsung cable? the 2 other micro USB cables work for data in my old US crapullar banter phone all day long. samsung tech told me to reset the phone and try again or exchange it for a new one. now I have to redo all my crap on my phone. liked the phone and was worth breaking a contract with us crapullar that i had for 10 years till now.
I find the drivers are finicky.
I can plug it into my computer (both work and home; Win7 32/Win7 64) and sometimes it finds it and sometimes it doesn't.
When it doesn't, I simply unplug the usb from the phone and plug it back up.
When that doesn't work, I will plug it in and then reboot the phone. That almost always does it.
When that doesn't do it, I will unplug it, turn on or off USB Debugging mode.
I've never had to uninstall/reinstall drivers for this phone. The computer installed everything automatically.
edit: The one thing I did find, however, is that with my old Moment USB cable, it won't charge properly. It always says 100% charge after about 5 minutes even if the phone was dead. So I don't listen to that one and just use it for data transfer when I'm not using Dropbox.
i can charge the phone no problem but the data is the problem. tried everything you said last night with a couple of samsung techs even the next level tech
should be a sticky. need to use rear USB ports for this phone because they are the only ones that work most of the time, and phone Micro USB jack is the cheapest jack ever. dont expect much out of it now, being sprints top of the line phone and all.

[Q] USB connection not working

Hello everyone, this is my first post and it´s about my Defy, which, for some reason, the USB port does not work to access the phone and/or the SD Card.
1: I did a soft and hard reset and the problem persists.
2: The phone does not show up on the device manager under Windows so not even an error message saying "Device not recognized" or something. Also, it won´t show up in Ubuntu.
3. The "Connect your charger" message shows up all the time.
4. No notification in the phone when plugged to the PC .
5. Even though I can´t access the phone from the PC, I still can´t charge it through the USB port.
6. I can connect/access the phone and SD Card using Wi-Fi (Motorola Phone Portal) but not USB. I can see "Plug in USB to launch" in Phone Portal but cannot press the button, only the one referring to Wi-Fi.
PS: This is my second Defy, the first one got the same problem so I got a new one... sadly, the it happened again.
PS2: I wonder if a USB 3.0 port has to do with anything? It´s the only thing that I noticed before the USB stopped working.
Any help or hint is greatly appreciated.
well, i don't think it's an usb3 problem ...
to be sure you could try to connect your phone with an older usb2 port computer ...
is the phone charging on wall charger and usb-cable ???
if not, it really sounds like a hardware failure ... then i would send it to customer service and tell them that there is the same problem again .. maybe the just repaired something and it's faulty again ... be sure, that they are changing the faulty things ...
if your phone is charging on wall charger, it could be that it is an problem with your pc ... try another one ...

1. I mentioned the USB 3.0 port because it was the only common thing just before the usb conection stopped working.
2. The phone charges normally using the wall charger or usb (2.0, 3.0) cable through the PC.
3. It does not matter what PC is connected to or the OS (Ubuntu, Win7)/
Thanks for the response!
It is possible to brick it. Wtih some phone's it seems to be a common error for usb ports to be blown.
Could also be the cable... My cable that came with the defy was already snatched after a few months. My screen started going on and of when I was charging it.

Is there a way to check for faulty hardware-related issues?
just test different cables, computers or even mobiles ... then you will see, what is faulty

What I meant was some software that check or even some kind of physical device.
Anyway, I know it´s not the cable or PC faulty but the phone itself. But I want to confirm if it´s software or hardware related and if there´s a fix.
Thanks!
Try using USB with logcat open. You might see something in the log that will tell you what's happening

[Q] Is my micro usb port broken? Help!

Guys,
I have a A501 32GB 3G model and I think my micro USB port might be broken.
I can't remember when but at some point, my computer stopped recognising my A501 when I connect to it via micro USB. For awhile I thought it might the custom ICS rom's fault as the normal USB port wouldn't work either, but when I reverted back to Honeycomb this week I noticed the normal USB would work, but my PC still couldn't recognise the tablet when connected via micro USB.
Is there any way to test the port? I don't even have a spare cable I can try to see if it's the cable's fault.
I'm planning a move overseas in a few weeks time so I don't think there's enough time to send it in for repair under warranty. What a hassle....
Has anyone experienced same problem? I don't really use it much but it bugs knowing something's broken when it's only 4 months old...
Thanks in advance.
Mine has intermittent issues, but in my case, it is the cheap cables I'm using.
I would go to Best Buy and pick up a cable (normally I would say order one from Newegg or somewhere like that, but it appears time is of the essence in your case) and see if that isn't the problem. Or...borrow a micro USB from a friend. Either way, try to eliminate the cable quickly (as that is the easiest and quickest route to go).

Sounds good. But, I also might try re-loading the PC's drivers for Android also.
Never heard of a micro-usb going bad. Not yet anyhow.
Micro USbs fail on phones all the time, it usually happens when the user isn't delicate with the connection while unplugging or plugging in the cable. The port technically doesn't fail, but the soldering connection to the circuit board does. I would first look at a bad cable. Don't you own a cell phone?? Even Crapberry uses micro usb for its charging data cable now try your cable from your phone or digital camera??

[Q] Nexus 7 charging problems.

One of my clients recently purchased a Nexus 7. Two days after opening the box he said it would no longer charge. Not only that but he says he got a "Power surge on USB hub" error when he pluged it into his Windows 7 computer. I thought that was weird and asked him to bring it in so I could have a look at it. I plugged it into a USB port on my work computer and I got the same error. Not only did I get the error, but it took out one of the USB hubs on the motherboard. I asked the customer to check his computer and he had the same issue, the USB port he used to plug the Nexus 7 no longer worked.
I've tried everything to get the ports working again, reinstalled drivers, etc... with no luck. I'm of the opinion that the onboard USB hub on both computers for the non-working ports are dead. Anyway, I was wondering if this has happened to anyone else? I'm sure the "we're not liable for damage" clause will cover Google/ASUS ass, but if someone has had the problem, did they have any luck getting Google or ASUS to fix their computers?
Thanks

I'm getting that lately too everytime I plug mine into the computer. However I can plug other usb devices into the computer and don't get the error.

note 4 version not connecting to computer or fast charging

ive replaced the usb port, fully updated the phone, tryed a friends battery, new charging brick and cords , tryed different
outlets and the phone will not fast charge or show up on the computer/any computer.
when i plug it into the computer i get a error message:usb device not recognized or malfunctioned (i shortend it)
much help needed please and thank you
With regards to the fastcharging part, are you also sure you are using an adapter that supports 2Amps at 5V ? This is also the spec of the original adapter that came with the phone (I also found that it works with different 2.1 Amp. adapters generally for tablets)

I have the same problem. I changed the USB board but the problem was on the motherboard. I test all possibilities soft and we did. I changed USB card, USB cable and nothing. I went to a service and said that it is guilty USB chip on the motherboard. True or not I do not know but the man said he changed and now it works. It cost $ 50. He said it's a motherboard intervention more difficult.
