Samsung j1 is among the phone of jseries which has a small brain in terms of memory(pea brain) and that it got only 760 mb ram which adds the most dirty tag to the phone, camera quality is just fine, mobile speed is low as it got 1.2 ghz quardcore, being 4g it must be upto 1.7ghz atleast! It got 5mega pixel real camera which is fine and 2mp front camera, being a 4g device it must be near to 4mp which it lacks! The battery backup is just extreme it got 1850 mah battery which for 4g is worse. In short the device costs 6.8 k and which is not really woth for this junk
