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 p...
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
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!
We are experiencing the same issue with Intune. I believe it is related to what Jasonbayton is talking about. The settings in the Intune portal are Block or Not Configured. I think that is why the default value is "null."
Are you saying you used MS Graph to modify the Device Restriction Profile explicitly to "true?"
So, you went around using the Intune Portal?
No I did not change values by using graph api. I wondered why test devices were able to use usb file transfer but production devices did stop working.
I used Graph API to compare the values in the graph api response because the admin UI showed „not configured“ for both. But the results on the devices differed.
After the dummy edit they values were the same and functionality came back on the devices so I closed our case with MS.
