Usually, Google Play will not allow me to install an app that is not compatible with my device. It is very frustrating to install and then be told it is not compatible. Can’t you mark the (in)compatible hardware in Google Play? At least, “phones only” (I’m trying to install on a Nexus 7 tablet).
Android tablets are not yet support, it is in the road map, [iOS just entered beta I would expect Android tablets to be next on the to hit list]
I agree that until Android tablet support the Google app store should limit to the approved Republic phones [3.0 and legacy]
