Blocked USB file transfer
We are struggling with some user reports about blocked USB file transfer functionality on their Samsung A52 / A54 devices enrolled with corporate-owned work profile.
Microsoft released a blog post about this issue here.
Known Issue: Some management settings become permanent on Android 14 - Microsoft Community Hub
We stumbled across the one-time hint about "do not upgrade non-Samsung devices to Android 14" in the advisory. Did not find any other information whether Samsung is also affected or not, but as we only have Samsung as corporate devices this seems also to apply to Samsung devices. After factory resetting the device and a fresh enrollment the USB file transfer is working as expected / configured!
*15th March: please note: this post has been moved and been made into a new topic and new title
Be aware also Google changed out the default behaviour of usb when left unconfigured, which aligns with the experience you're describing.

Hey everyone,
I hope you've all had a good week.
Just wanted to come back to you. To clarify the change mentioned by jasonbayton above was updated by Microsoft Intune. I know there was a bit of uncertainty mentioned so just wanted to confirm this.
From our own testing, as you mentioned Weberda, it appears toggling the "USB File Transfer" policy setting from "Not Configured" to "block" (save), then back to "Not configured" (save) will enable USB file transfer. I believe Microsoft are working on an update to iron this out.
If you continue to have difficulties though, please do contact Microsoft Intune directly and they can advise you further.
Hope this helps and do keep us posted if you can.
Thanks again,
Lizzie
I have been informed that Samsung devices are not affected as they identified the issue before releasing the Android 14 update and implemented a fix, unfortunately nothing publicly available.
😮
uh interesting... it's hard to investigate as i can't reproduce the issue on my device after factory reset but users are complaining about the missing functionality. All of them told us that they have used the usb file transfer for their photos before and sometime in between this has stopped working.
Ugly situation... "to be able to file transfer your photos again, you have to factory reset your device. please be aware your photos will be lost after the reset" 🤔
I would suggest double checking the policies and looking at the DEBUG logs on the device, then escalate to your EMM provider if necessary
Device Policy App on an affected device (A54):
deviceConnectivityManagement: {"usbDataAccess": "USB_DATA_ACCESS_UNSPECIFIED"}
On my factory reseted and fresh enrolled device (A54):
deviceConnectivityManagement: {"usbDataAccess": "ALLOW_USB_DATA_TRANSFER"}
100% sure it is the same policy and groups for those two devices...
Hello weberda,
I hope you are doing well.
Thanks for highlighting you are experiencing this. I've had a look and we do currently have an newly opened ticket for something very similar to what you are mentioning here and our engineers are currently reviewing it. On this grounds I currently think this is unrelated to the service announcement you posted in.
I hope you don't mind, to make it easier to find, I've moved your posts and made them into a dedicated topic, which will make it easier for others to find and update. If you would prefer a different title, just let me know and i'm happy to update it.
To add, if you could also report this via your EMM please, so your information can also be captured on the ticket, that would be fantastic.
Thank you again and I'll keep an eye out for updates to share with you.

( davidguillaume, thanks also for your useful replies here, FYI on the above 🙂 )
Lizzie Thank you!
We were able to solve this issue by re-saving the config with the same values.We are using Microsoft Intune as our EMM, maybe this is only related to Intune! We found out that the policy values we grabbed by MS Graph API differed ("null" value instead of "true/false"). After our dummy edit the values changed from "null" to true/false and the Android restriction has been updated after the update and USB file transfer was restored on our device fleet.
Maybe this helps!Be aware also Google changed out the default behaviour of usb when left unconfigured, which aligns with the experience you're describing.

Thanks everyone for your updates here, this is super helpful. I'm highlighting this back to our team internally, but please do continue to speak with your EMM about this directly.
As soon as I hear more, I'll update here. Thanks again.
