Previously I owned a Moto g 3rd gen but when I upgraded to Moto g4 plus it completely changed my experience with a tons of new features with the biggest improvements in the history of Motorola phones till Moto g4 plus, a big screen of 5.5 inch makes your day with access to the latest version of android 6 easily upgradable to android 7
If you want a phone in a 15k budget just go for it??
