This is my fourth Samsung Galaxy device. I have never experienced an issue as confounding as this.
Specs:
Samsung Galaxy S24 Ultra, 512GB
Phone model: SM-S928U
Android version: 14
Notes/symptoms:
By "suddenly" -> I mean suddenly. I have owned this phone for approximately 3 months. During that time, everything was working fine with USB-C data transfer to computer. Now it is not detectable.
By "not detectable" I mean it will not trigger any notification on either device (phone or computer), nor will it receive a charge
Device has no issue charging over USB-C when plugged into a wall outlet, however it will not charge over USB-C when connected to a computer.
Device is in pristine condition, was purchased new from T-Mobile, is not rooted, and has had no other issues.
It is NOT the cable. I have tried multiple high-end cables, including the one that it came with. As a former systems administrator, I am certain that it is not the cable.
It is not the computer. I have tried various operating/hardware systems: Ubuntu 24.04, macOS 14.4.1 and 12x, Win11. The OS I was previously in the habit of connecting this device to with USB-C is macOS.
The only odd thing I've done, is rather than using Android File Transfer, I had previously been using the OpenMTP application on macOS for file transfer between my MacBook Pro and S24 Ultra. This was working great for 3 months. I don't think this is related to the problem, but it ought to be noted.
Things I have tried:
Rebooting, everything, a bunch
Connecting to various operating/hardware systems: Ubuntu 24.04, macOS 14.4.1 and 12x, Win11 (it's not the computer... it's the phone)
Connecting with different quality cables
Uninstalling recently installed apps, turning off Nova Launcher
The lack of an SD card slot on the s24 Ultra is infuriating! It has magnified the impact of this issue 10-fold. I have no way to--locally--retrieve or backup nearly 500GB of data off of my device. What are my options? Attempt to Bluetooth 500GB of data? The lack of an SD card socket is inhumane.
I am now attempting to wirelessly send half-a-terabyte of phone data to the "cloud" as the kids call it lol! Expecting that to take some 24 hours. Then I will perform a factory reset since it's the only thing else I can think of to try. Please help. Please don't make me send my phone to fix this.
Can you plug your galaxy 24 using the USB side for the electric that is placed on a wall plug and then just put the other end in to the phone. I hope that makes sense
Not sure if you fixed this but ran into the same issue. It was a recent update with windows. Now you have to go into your windows computer to allow your phone to be connected. It's called link my phone. You can search it on your computer or here is a link from microsoft. This has resolved my issue. It's now connected via Bluetooth and I you do have to allow window link notifcations on your phone but it walks you through this when getting it set up. So connect to your computer via usb to c-port and then set this up and it's not the exact same but you have access to all information on your phone now, so you can get your files or images.
I had the same issue; until some weeks ago it was simple: I plug in my cable usb-c to usb-a in my windows 11 and I see "Galaxy S24 Ultra" in My computer as a external memory; then I can open it and copy and paste everything: images, documents and so on. Now I don't see any more the icon, I need to activate "phone link" on windows but it's not what I want! After activating phone link I can enter the phone memory but I cannot transfer files easily: after many attempts (!!) I found it's necessary to activate OneDrive, so Windows uploads all the files on OneDrive and only then I can download them on my pc.
I think this is VERY annoying, I'd like to go back to previous way, but I can't find how to do it!
Do you think it is possible? Or we are forced to use phone link?
Same here. What's going on Samsung my USB-C is no longer working. I tried all the above with the same results. There must be a patch for this issue. Samsung look into USB C issue.
Same issue here on wife's s24u - it will *sometimes detect USB if USBsettings app has data cleared, then reset. But not everytime. Unbelievable that this is still an issue over a year after release
S24 Ultra. External monitor works 1 out of 100 times you plug it in. I am going to wear out the USB port. I spend the first 10-20 min of my day unplugging and plugging my phone into the external monitor. Monitor works fine with every other USB C device. Only my S24 Ultra fails 99 of 100 attempts.
