Samsung Galaxy PRO Summary The Galaxy Pro series functions along similar lines to the Galaxy Prime series; the most notable difference between the two is the fact that the Pro series mostly consists of upgrades to higher-end smartphones while the Prime series is situated in categories below lower-mid. Some notable examples of the Pro series include Galaxy A9 Pro 2016, Galaxy C9 Pro etc. among others. The Pro series, as mentioned above, mostly upgrades higher-end smartphones which is why most (not all!) of its devices cost in excess of 45,000 rupees. They’re very very powerful, have some excellent specifications and they re-improve an already fantastic device.
