Samsung on5 is average phone with decent spects like, 8 gb internal memory, 1.5 gb ram, 8mp rare and 2mp front camera, phone also have 3g and 4g support. display is disappointing because it is normal lcd capsitive 5 inch screen, but screen is quite bright. on5 comes with lollipop 5.1 and as we know samsung never give leteat update to mid range or bujet phone. so chance of getting marshmallow 6.0 update is very low. but lollipop runs well. no lagging issue on this phone. but some screen drops occur during havy gaming.
people who want samsung brand, without investment of bunch of money then on5 or 7 made for you.
