What is the Difference between GMS, and Non GMS models of Enterpise Android devices?


GMS stands for Google Mobile Services. Google Mobile Services is Google's proprietary suite of apps (Google Play, YouTube, Google Maps, Gmail, and more ) that run on top of Android.  In order for a device to take advantage of any of these proprietary apps, the Android build must be licensed by Google.  Without the licensing, none of these services, including the Play Store, will be allowed to run on the device.
