From the recent update by Jolla it is confirmed that Sailfish OS is now fully compatible with Android. This Linux based OS is capable of running Android applications. More to that, Sailfish OS can be flashed & operated on hardware designed for Android (that's the best part !) CEO of Jolla Tomi Pienimaki told ZDnet that,"We have tested quite few [Android phones] ourselves,” Pienimäki was quoted as saying. “We have simply bought a device from a shop and then installed Sailfish on it. We’re confident that you can run this on quite a few different Android hardwares." Mozilla Firefox OS : doesn't support Android compatibility, but supports easy porting of the Android applications which are based on HTML5. Ubuntu's Touch : Doesn't support Android compatibility too, but they're aiming to offer the users to dual-boot their smartphone & switch between two as per user's choice. Tizen : Intel & Samsung backed Opensource OS reveals no news. Jolla Sailfish : Supports Android compatibility. Can Flash Jolla Sailfish in hardware designed for Android phones (hence you can run Sailfish in your current Android devices, most probably) Share your views, CEans.
