I found Enterprise Management Client in the App Manager. There is no option to uninstall it, just the option to Disable it. When I try to disable it I get the following warning "Disable built-in app? If you disable a built-in app, other apps may misbehave."
it's listed as Version 18.104.22.168. I've googled it and I can't find any info at all.
FYI it's permissions include Location, Messages, create Bluetooth connections/full Internet access, Modify/delete SD card, take pictures and videos, etc..... Although it appears to be a built in app, I sure don't care for it's permissions.
