Samsung Dex issues - Samsung Galaxy Note 20 Ultra Questions & Answers

Samsung Note20 Ultra, OneUI 4.1.
PC: Win10 21H2,Dex 2.4.0.29,SAMSUNG_USB_Driver_for_Mobile_Phones 1.7.56
Issues:
Befoe installing the USB driver, with "transfer files" option enabled in the phone, the phone is shown in the the PC's windows explorer. But after installing the USB driver, although the option "transfer files" is still enabled in the phone, the phone is not shown in the PC's windows explorer, so I can't transfer files.
After installing the USB driver, the Dex on PC will prompt you to connect the phone, and it was successful. But after that, Dex never prompt you again, and I can't connect to PC Dex via USB cable.
In the phone's Dex setting, my PC can't be found under "Dex on PC", but can be found under "Dex on TV or Monitor"

[Q] Samsung Galaxy Ace II - Disable MTP?

Hi all,
I've a proud owner of this I8160 phone. I'm glad of it, but the problem is that I can't access to the SD external's contents.
Firstly, I can get the USB working on PC by enabling it on "Settings -> Wireless networks -> USB settings". However, external SD (empty folders "external_sd" and "usbStorage" make me guessing about it) is not accessible, and I don't know how to get it.
I figured that "MTP connected" note on the phone has to be involved, so I tried to disable it. Searching in the web points to that USB debugging must be enabled; however, this won't perform anything new.
Hence, my question is, do you know how to disable the MTP connection on this phone? I want only USB mass storage, no kies at all!
Any ideas? Rooting may help?

No need to root your phone if you just want to transfer files. I have the same issue as yours.
Here's what I did:
1. On your phone go to settings>wifi and networks>USB Utilities
2. Do not connect the cable to the pc yet, tap first the box on the phone saying connect to pc (something like that)
3. Then connect the cable from the phone to the pc, a green android will appear then
You can now transfer files from your pc to your phone, vice versa.:good:

USB Tethering - Unidentified Network - No Internet Access

I am attempting to USB tether Internet access to a desktop with a fresh install of Windows 8 Pro. The process works flawlessly on my laptop, which already has WiFi Internet access and is running up-to-date Windows 8.1. There is no software or updates installed on the PC, aside from that which comes with Windows 8 Pro. Windows Defender/Firewall are disabled.
The PC does not recognize anything stored on the GS3, whether set as MTP, PTP, or neither, making it difficult to attempt transferring drivers. I have a UWF-1 wireless LAN adapter meant for Onkyo receivers, but it shows up as "UB93" with an exclamation mark in Device Manager. I've located potential drivers for the adapter, but I'm unable to transfer them from my laptop to the PC without the PC recognizing files stored on the GS3.
I have a single DVD-R I could use to transfer, but as it is the only method of transfer I have available, and I have single disc, I want to load it up with all potential fixes I can come up with before burning.
Any suggestions to get either USB tethering or the wireless LAN adapter functioning? or getting the PC to recognize files stored on the GS3?

Lost connectivity

I have, successfuly, upgraded my Samsung galaxy tab 2 10.1 tablet to Marshmallows. BUT it seems that I have lost the communication facilities with the W10 PC. A unit correctly labelled GT-5110 appears (icon looking like a music unit) but the folder is empty (should contain an internal and an sdcard1 reference). Loading Kies which should supply the driver does not help. USB has been set to MTP on the tablet but Samsung MTP driver available in W10 does not work. I have also enabled Android debugging (ADB) in the tablet with no difference. Tablet or PC problems?

Can't connect to PC for file Transfer

Brand New Unlocked S8+... Tried to connect it to my PC to use a previous copy of smart switch backup but it never connects.. Windows Explorer never displays a mounted drive either. Smart Switch Eventually comes back with Failed to connect to the device.
The Phone displays the "Attention The connected device is unable to access data pm this device. Reconnect the USB cable and try again...."
Phone is on Transfer Media files (MTP)
USB Debugging is one.
Device Manager says "Samsung Android Phone - SAMSUNG Android ADB Interface" two times - No red or yellow exclamations.
I've removed the software in device manager and restarted both the phone and the laptop multiple times.
I updated Smart Switch and did More\Reinstall Device Driver.
Does anyone else have any workarounds for this? I found one article (https://www.recovery-android.com/connect-samsung-to-computer.html) but still no success.

I actually have the exact same issue on windows 10. Anyone figured out a solution?
Doesn't seem like there is much help here on the 2 Samsung formums I posted on....
I know its not my windows profile as I have tried 3 different profiles as well as safe mode.
Tried 2 different sets of Samsung USB drivers and no improvement.
Like I said I had no issues on a windows XP machine or a windows 10. I didn't even need to install the USB drivers/Smartswitch on either of those machines.
We can't be the only 2 people!

Firstly, i cannot give you direct answers.
Just my thoughts.
i have a S8+. No root stock as is.
I have Lenovo laptop Win 10.
From day one, out of box, i connected
S8+ and it connected. I can do whatever
i want. Transfer data, photos videos.
ADB etc
So it should work...?
However i do realize there are quite a few things to consider......
Samsung drivers on laptop and a few other
issues..... eg
For one,
have you enabled
in Phone /Settings /Developers Option /Usb debugging.?
Normally first time when you connect
With pc /laptop you should get
a small pop-up message(on device) to allow
phone to connect.?
(that's my experience, over years)
Good luck
Yes, USB Debugging is on and connection is set to MTP.
Windows recognizes "USB Android" but dosnt install the driver successfully.
It will appear as a modem in Device manager but nothing is mountable.
I have 2 desktop pcs with win 10. One with samsung software Kies 3 and smart switch installed and the other no samsung software. Both find the device Galaxy S8+, in device manager under universal serial device controllers i have Samsung Mobile USB Composite Device. You have an adb driver I think because you have usb debugging on, i would turn usb debugging off. The pc should find a device connected to the usb and download a driver, once done the device is recognised as galaxy S8+ in my case but will not communicate with the pc until the phone has given permission. On the phone will be a message asking you to allow the connection. Hope this helps ??

Firstly i do understand that you
must be quite annoyed trying to figure
out issues. (I would) Thankfully i don't.
Bottom line is that it should work..!
My experience confirms, that S8+/laptop Win 10 works.... 100%when connected
However a few suggestions.
If you feel you checked all checkbox.?
However you never said anything
about popup notice ? granting premission
for device to connect.?
So device /laptop /pc is not "seeing" each other?
All Samsung devices I have used, first time connection gives me this popup a notice
Can't remember exact wording.
Something... eg
Device id 5786446.......
Have or does your other Samsung devices
connect etc.?
Have you tried connecting to a friend pc laptop.
An option is to go to a Samsung Care Center
and as them to test and connect.
My experience (in past) is that they should
assist you.
If it connects to friend pc or Service provider /Samsung Care Centre.
Then surely it has to be your pc/laptop?
So I turned off usb debugging and revoked the permissions on the phone, connected it to my PC.
Samsung Android (with a Yellow Exclamation) was already present in Device Manager under "other devices" so I uninstalled that.... and rescanned. My laptop attempted to reinstall but it generated a Driver Installation Failed message on "SAMSUNG_Android" - no driver found.
Device Manager once again shows the Yellow Exclamation Point
I would go on to Samsung support look up the phone and download the usb driver and install from the download. Good luck
I've downloaded the drivers from Samsung 2x.

I can vaguely remember that i had this same
issues with my Note 5 and Win 10.
This was many months/year or two, ago.
I also had yellow exclamation etc.
Further in Device manager( laptop) kept installing wrong Samsung drivers.!
I uninstalled drivers/installed and battle for a few months like this Then one day Windows
did an update and in update i noticed
Samsung drivers included etc. (must have been correct)
Ever since that update i had no issues again.
Bottom line... some drivers issue?
Not S8 +?
Good luck

In the past I had this problem I downloaded USBDeview to my PC and deleted all of the old Samsung drivers, after rebooting the PC the phone was able to connect with the PC.
Tried USBDeview and removing the Samsung drivers but no difference
Still unable to connect.
I'm having this problem as well. I'm still trying to work it out, but when I remove and re-add the device through Device Manager I get this error: "An existing device was found that is a duplicate of the device being manually installed" and the device DOES connect as a camera, just not for full file transfer.
I had the same problem and tried many of the fixes, including different USB cables and different computers and different phones. I finally figured out that the case I had on the S8+ was the problem (at least for me). I took it off and everything works.
Hi, i have a pc with windows 10 . In device manager under universal serial device controllers i have Samsung Mobile USB Composite Device. i think you should meet best mobile shop.

I have Windows on Lenovo Laptop with latest Windows updates installed. Yesterday, I downloaded Samsung Smart Switch unlocked the phone and connected it to the laptop. Smart Switch found it immediately and I did a backup. I did not need to check Device Manager. It must be a drivers problem as mentioned above.
Note 8, getting "Attention The connected device is unable to access data pm this device."
And I am only able to see some files, Sammy is a crazy fool, this is basic stuff
installed the windows fall update a week ago now connect my phone to my laptop and nothing is recognised, no phone memory and no memory card just a empty space when i click the icon where my phone should be, i've had samsung drivers installed and they have worked fine so far till today, any ideas where to find the latest drivers? and what else i can do to get access to my phone on my laptop?
solution that worked for me
On my windows 10 PC, I opened device manager (open up start and just type 'device manager') and under portable devices there was a usb device called MTP USB device or something like that (I forget the exact name) with a small triange and an exclamation mark next to it. I clicked on that and then clicked "update drivers." When the prompt comes up I chose the automatically look for drivers option. This fixed the issue and now my Galaxy s8 is recognized (it no longer says MTP USB device or whatever it was). Hopefully this works for others as well. You can also probably download the usb drivers for the phone from samsung.

Computer will not detect tablet!!!

When I plug in my Nvidia Shield K1 into my computer it only charges.....
My old K1 was recognised by my computer immediately before so I don't know why this one won't work?
Please note these things.
1. I have tried a different cable and connector
2. It was purchased second hand and bootloader is already unlocked with TWRP installed.
3. Have installed all necessary drivers on computer
4. Have put tablet into developers mode
5. Have selected MTP on developer options
6. Nothing shows up in device manager
Have you tried with another PC?
Any notification on the Shield, that it has been connected by USB? And if so, select MTP (selecting MTP in Developer's Options doesn't always work on some devices).
You tried other USB ports on the PC? You said you tried another cable and "connector", so maybe by "connector" you mean the USB port on the PC? Also, don't use a hub, connect directly to the USB port on the PC.
If none of this work, and never did on this 2nd hands device, you may have a damaged USB port on the Shield.
Try going to Developer options - Revoke USB debugging authorizations. That has worked for me in the past. I would doing it with the USB disconnected then reconnect.
