I think it is a bad move for Android interoperability. Samsung has its own AirDrop. Oppo has its own AirDrop. I don't know about many others but its frustrating to not be able to use a feature, because you simply don't know other people with that brand.<p>Especially here in Germany the Smartphone market is dominated by Apple and Samsung, so good luck trying to successfully use Oppo Share.<p>I think it would be a better approach to implement these sorts of features natively and not force them into those dodgy reskins but rather incentive smartphone manufacturers into using them.
