Samsung Galaxy On5 is pretty much OK kind of phone for the price range. definately not for heavy users, considering the processor and the RAM, its definately not a heavy using phone.
The camera being 8 MP doesn't perform that well in comparison to other 8MP camera phones.
The touch sometimes lacks in responding to the stimuli, it makes wrong choice for the touch made thus creating an annoying problem.
The battery performace is higher average standard.
I think the phone is fine for those who just need a smartphone for using Whatsapp and Internet sometimes, and not for heavy users
