My brother bought this phone a few months back( almost 3-4 months) . He is truely satisfied after buying this phone. This phone performs well at every platform but lacks somewhere in gaming and a bit in camera too. It heats a bit while charging and playing games but I think its normal. Now coming towards the specifications: -
It has a 13MP primary shooter and a 5MP secondary shooter which clicks decent daylight images but somewhere lacks in indoor lighting condition( the picture comes out to be really noisy) . It has a 5.5 inch 720p display( viewing angles are good) and comes with android Marshmallow straight out of the box. It has 3gb of ram and 16gb rom with 1.6ghz octa-core processor, 3300mah battery( which lasts a day on average usage) , 4g volte is supported and Jio sim works fine
So thats all about the Samsung Galaxy On8. So overall its an average performer. Few better options are present in the market such as Redmi Note 4, Honor 6X, etc. But Samsung lovers can surely go for it.
