Samsung Galaxy S7 - This device is owned by your organization

Thank you !
Like h5g2 or @VinK3645 , I was also very surprised to discover the message “This device is owned by your organization”
Unfortunately, the ADB commands don’t work on Galaxy S7 Herolte (with official last version)…

adb root
adb shell pm uninstall --user 0 foundation.e.mdm

(same thing with the command : adb shell pm disable-user --user 0 foundation.e.mdm)

=> Command output
Failure [DELETE_FAILED_INTERNAL_ERROR]

or, with disable-user :

Exception occurred while executing 'disable-user':
java.lang.SecurityException: Cannot disable a protected package: foundation.e.mdm
...

Do you think another solution to uninstall or disable MDM is possible?

Thanks for your help !

PS 1 : I saw on another post from @Manoj :

But will S7 get the 3.1 update?
If yes, when? (it seems far away…)… perhaps it is safer to migrate to another OS (LineageOS…) in the meantime.

PS 2 : Thanks a lot @Manoj !
