I’m a big fan of moto stock android devices.
I used moto G2 before and later I updated to moto g3.
As we know moto g3 have got 2 gb ram, 13mp+ 5mp, ambient display and water proof. Apart from these features there is nothing impressive.
Difference:
Moto g2 is more responsive with ok google commands
impressive and stylish design
notification led is beautiful
sound quality is awsome
Above features lacks in moto g3. Please update camera options with more professional tools, and next update we expect some more features.
