NFC blocked by security policy
Have you checled whether the "Change System Settings" permission of your device agent has been enabled on your problematic devices? You can check/configure this option under MobiControl device agent app item in the App Manager tab of your device's Settings.
I made a test, it's already granted on app manager of my device.
What I didn't undertstant is when I just update the profile by renaming the profile and assigned it, the problem disappeared on some devices, but appears on other devices...
As your ten devices are running dfiferent Android firmware versions (7, 8 or 9), the underlying Knox libraries may also be of different versions. Could you please check if all problematic devices are running the same android version?
Please also verify that the version and build numbers of all 10 devices are the same?
In any case, below is the link to see my issue on video:
I don't think that issue is due to devices, but mainly due to SOTI issue because last week all devices was working correctly with NFC tag.
Since we updated their profile, most of them got the issue. If I reassigned again the profile, some of them will work correctly and other ones won't work.
We have almost 5500 Android devices on SOTI everything was working correctly before we change the template to add a new link.
Approximately 150 of the 5500 devices got NFC issue due to security policy whereas other devices with exactly same settings/versions are working.
The issue is, why assigning profile (just with new name) is solving this issue regarding NFC???
Please note that this issue appears on all OS version from 7 to 9.0
In any case, below is configuration of a device wich didn't work (until I reassign same profile on it):
SOTI support sent me the solution below which was working fine:
1. Disable "Package Blocking"
2. Enable "Samsung Package Disabling"
Hope thsi will help some other users.
