Bixby, Samsung's new virtual assistant that exists only in the new Galaxy S8 smartphone of the company, can and does work on all major Samsung phones running Android 7.0 Nougat.
Not officially, because what we described above is a result hacking. A developer with the nickname takerhbk on the well-known XDA-Developers forum managed to get Bixby working via an S8 launcher that was leaked earlier this week. 
takerhbk has since started sharing the necessary files of its APK applications Bixby, and the APK of the launcher.
Mishaal Rahman from the XDA-Developers forum reports that he managed to run the digital assistant at Galaxy S7. There were many others who succeeded in bixby's porting on their own devices.
According to Samsung, Bixby will not be released on the Google Play Store.
Note that older Samsung devices, such as the Galaxy S7, do not have a dedicated button to access the Bixby mode as it has Galaxy S8, which is already available for pre-orders at prices starting from $ 720. So the experience of a Bixby digital assistant on older devices could be very different.
The digital assistant Vixby is not the only assistant you can use on a Samsung phone running on Android Nugat.
Google is preparing to make Google Assistant available on Android Marshmallow and Android Nougat mobiles. Microsoft's Cortana is available on the Google Play Store, and the Amazon has begun distributing its own digital assistant Alexa to smartphones. Of course, Apple's Siri is only available for iOS.
