I have many different Android devices on multiple version of OS. SC is only required for those that do not support hardware encryption. The setting in EMM for policy is set to not require SC, but block devices that do not support encryption.
To setup an android without SC on EMM. We join the phone, encryt the phone, complete EMM login. Then add the account manually (skip / say no to SC install) and everything works. But this ONE phone model is causing issues. the Moto Rzr Maxx will not work without the SC, and it is on OS 4.x and supposedly supports encryption. WHY!?!?!
I'm on EMM 10.2.4 and should be up to date on device catalogs.
