we have a lot of device zebra TC75X.
I have migrate the device all device under android 6 to android 7 in the begining of this year without any problem.
But I would like to know if I have make some error or not ...
We don't have any google account on our device so, I have downloaded the zip for to upgrade the device on the page NO GMS.
It's just for my knowledge, how I can identity a device GMS and a device NO GMS ?
And also, a device in GMS can be upgrade to no gms and the revert is also possible ?
Also, what is the BSP could you explain me in some word ?
thanks for your time
