Probably an old issue, but I have several Galaxys phone, all work okay with the various leads I have on the laptop I use, but.... my S7 doesn't. Standard stock rom, no mods. I've changed the developer setting, reset, rebooted, changed leads, changed laptops, changed phones... all to no avail..... No pop up, no recognition of it being a USB connection - but it charges via usb through any lead, any laptop.... just will not act as a USB device...
No changes made or happen to the laptop either - tried looking in device settings to see if it's there - nope!
Now I'm sure it used to work before Nougat update...so could this be the issue? UK Vodafone on Nougat 7.0.. any advice would be welcome!

Completely bone-stock S6, I'm having an issue where something I'm deleting/disabling/a setting is completely turning off the data component of the USB connection.
What I mean by this: After a factory reset, the phone works perfectly. It connects via USB and allows me to select either MPT or PTP mode no problem. However, as I start removing the bloatware from the S6, something is happening that causes the S6 to not be able to connect to ANYTHING. I've tried multiple computers, cables, nothing works.
When plugged in, I get the "charger connected" notification and the phone charges fine, but now there's no option to select MTP or PTP mode. The computer doesn't recognize a device has been plugged in at all.
Someone else reported the same issue here:
http://android.stackexchange.com/questions/109991/galaxy-s6-not-seen-by-pc-at-all/110752#110752
but no one resolved it, and the answers posted were given by people who didn't seem to understand the question at all.
I'd really prefer not to have to factor reset AGAIN, and clearing the phone of bloatware/getting all of the settings updated involves dozens of steps, it'd take forever to do them one at a time to figure out what disables the USB "driver" or whatever it is on the phone that allows it to communicate.
I just bought a used Verizon S7, and everything so far has worked perfectly with the exception that it is not recognized by my computer. When I plug in the USB, the phone only charges and does not even appear as a new device in Windows (10 x64). I have already tried installing and reinstalling the Samsung mobile device drivers, without success--same with Kief 3 and Smart Switch. I've tried every USB port on my laptop and PC (and my wife's MacBook).
I have already enable developer options, oem unlock, and usb debugging. I have also tried changing the USB configuration in the developer options menu (MTP, PTP, etc). What I find really strange is that "touch for other usb options" doesn't even appear under the notification bar. When plugged in, it simply says "charging."
I have tried factory resetting multiple times. I also tried upgrading the firmware to beta 7.0. Nothing has worked. Please help.

I have a note 5. With similar issues. Ended up being a bad usb circut board.
Would charge most of the time but no usb connections. In the end wouldnt charge either.
If u need to transfer files try a app called wifi file transfer. That and wireless charging was my best friend.
The notes usb circut board has the home and touch keys attached so it wasnt feasable to risk separating the screen and outer glass for a 6 dollar part. Not the s series may not be built the same.
That's interesting, though not very reassuring. Any ideas about the missing "touch for other usb options" under the notification bar? Since the phone is Verizon and already carrier unlocked, my plan was to flash to SM-G930U. But that is obviously not possible if I can't connect to Odin. Any other suggestions?

No my note 5 is stock unrooted no other way to do anything other than adb over wifi.
Hello all,
I'm fairly new to this phone but I have been loving it so far. I've had a few issues with it, which most have been resolved (such as the phone defaulting to loudspeaker on phone calls).
Now my biggest issue is the USB connection. I first noticed it when I used to llug the adapter in for my headphones. The port worked great for a time and then I believe it was a security update that was released which seemed to jack it all up. Now I cannot use the port in the bottom of the phone for anything other than charging. Cannot use the headphones, cannot plug in my drone mavic pro (requires the phone app for on-screen first person flight), and I cannot plug the phone into the computer for data transfer.
I have pulled out the book of from my IT troubleshooting days and tried these solutions with no luck.
•various USB cables
•went into settings while phone was physically connected to the computer under connected devices, the USB section was greyed out stating not connected.
•checked in developer options us debugging on and off. I tried both ways for good measure.
•checked USB configuration type. I tried MTP, PTP, and RNDIS.
Any ideas?

I recently had similar USB symptoms on my Pixel 2 XL after the March security update. Also tried it in safe mode and tried factory data reset, but neither helped. I asked Google to replace the phone. Replacement works great, even after March security update.
Umm..I just recently had this issue. TBH I used a 3rd party cable but until last week it could 1. fast charge and 2. transfer data (included adb/fastboot), now however it does only charge, no whatsoever signs of connected device. Bought a new one, it does charge, sync(fastboot, adb,..), no fastcharge but ok.
Have you tried reflashing the March ROM (with the -w removed)? I'm running the March update (did the February too back in February) and I can still enable MTP (I just don't like that it doesn't stick in Oreo - coming from KitKat, that was - and still is - annoying.)
So I tried flashing the March update again and still had no luck. March update was a security update so whatever they did it must be in the coding. I got a warranty replacement for the phone and it works fine. I'm able to do data transfer and fast charging. I was very reluctant to install the March update again but after ignoring the notification for about a week, I installed it and it is working fine.
I talked to Googe about the issue and they said that the bug was fixed but for those phones that had the firmware installed, it has the issue permanently installed. The only option would be to replace the device.
I have run into a weird problem with connectivity on my u12+ recently and was hoping to see if anyone had an idea to resolve it.
The phone will not be recognized by any computer as a device. This is across Win 10, 8 and Mac across various devices. It will only be recognized as a device if booted into recovery/download/bootloader/fastboot.
It WILL charge across all devices and is obviously connected, just not recognized when booted into regular Android.
It IS detected on the same computers and cables when in recovery/download/bootloader/fastboot.
I have tried multiple cables, ports, etc.
The phone is rooted and on the latest firmware (1.21.617) with Magisk/Xposed
Restored with RUU fresh and still had the same issue.
Stock and untouched kernel.
In settings:
USB Connection - Shows None
USB Debugging - Have tried enabling and disabling with no success
Developer Options - Tried enabling and disabling with no success
USB Configuration - Wont show anything other than Charging, wont change if attempted
It did work initially but just can't seem to figure this out! I know the kernel can control some USB stuff (At least on my 10) but since I have not touched the kernel, I was holding off on that to see if I could resolve it first.
Does anyone have any idea?
Could the build.prop somehow have been modified? If so, is the process for viewing and editing it, the same as the 10?
I was thinking of looking at:
service.adb
service.debuggable
sys.usb.config
service.adb.enable
Thanks!
Can anyone please provide their stock build.prop so I can compare mine with theirs?
Thank you
For some reason I can't connect my Pixel 4a to my PC with a USB C - USB A cable (or USB A - USB C, not sure what the official name is) , even though it worked fine on my previous phone.
Included with the phone is a USB C - USB A adapter, but I see no use for it unless you have a special USB A cable which I don't.
My motherboard does have a USB C slot on it and it does read my phone when I plug it in that way but for some weird reason it's really loose and doesn't stay connected unless I keep physical pressure on it.
I'm not going to update to Android 11 until the November update because I've heard the current build has a few bugs, but does anyone know if Android 11 fixed the USB C - USB A issue?
Have you made sure to switch to file transfer mode? It defaults to 'no transfer' mode when I plug into my laptop.
Most likely you need to toggle the phone connection settings to data transfer, originally it will be set to charge only I think.

I had this issue too. Windows file explorer would just crash after one or two files and stop transfer, no matter the size and type. (Yes I had file transfer selected on my phone ?)
Then windows update gave me a driver called "Google Inc. - Other Hardware - Kedacom KDB Composite Interface". I also updated to the newest firmware on the phone. No idea which of these did the trick or if it was the combo. However. Smooth sailing now ??
Hope this helps
(If windows update refuses to give you the driver, you can get it from Microsoft's update catalogue online. A Google search will do)
Ok it's completely messed up. When I search for USB settings it doesn't let me change anything at all, even though when I first got the phone I could and I changed it to transfer files. EDIT: No actually the setting that I changed was a developer option called "Default USB configuration" which I changed to transfer files but that still did nothing.
I just plugged in my phone and looked for the USB setting in the notification area but it wasn't there, but I noticed an option called "manage"
I went in there and noticed this. (see attachments) it's locked to be off and I can't change it. Very odd.

You're in notification settings. Try short tapping rather than long tapping to get the menu to pop up allowing you to select data transfer.
Changing default USB settings in developer options doesn't work for me either.

My point is that the notification that normally comes up when you plug in your phone to a computer to change to data transfer, charge only ect ect isn't even coming up because the firmware is stopping that notification from coming up altogether and I can't change it so it does.

Almost certainly a cable or host port issue. Swap cables and see what happens. Same for hosts/host ports. You're not going to have toggling options if the phone does not 'see' all expected lines/pins.
I had the same issue and changed to a different cord to fix the problem.
You have an non certified cable it seems, I've confirmed this pixel 4a works with only certain cables for usb transfer, also the usb a to c cable you have will not charge the device as well.
Get a cable from know manufacturers like Samsung, it worked for me.
Yeah turns out it was a cable. Strange how my cable worked with my old phone but not with the Pixel 4a
Had this issue with my new 4a just now. Cable was fine, even used the new cable that comes with it using a Usb C to Usb A adapter. Nothing worked. Upon opening Device Manager I found a new device called 'Kedacom USB Device'. After trying random things, I decided to uninstall the current drivers by right clicking on it and clicking 'Uninstall device'. Suddenly the phone connected, and even showed the adb prompt.
So for anyone still facing this issue, hopefully this solution might help
