BLE Scan problems with Samsung devices

I worked on an application which use a BLE scan into a foreground service.

I used ScanFilter in order to get scan results when the screen of my phone is locked.





When I used ScanFilter with mac address it worked great but it’s not a real solution because I don’t want to specify all the mac adress for all of my beacons.


So I try to use ScanFilter with service data id, it worked except when the screen of my phone is locked.

 The problem is only when I use my app with a Samsung device because I have a Pixel 3 and I don’t have the problem.

Do I need to install Knox SDK in order to unlock the scan ?

Thank you !
