Samsung galaxy j2-6( 2k16) is a smart choice in this time because Samsung is giving a mobile with perfect specifications in just rupees 9, 700/-
It has 5.0-inch display, 1.GHz processor, 8 megapixel rear camera, 5 megapixel front camera, 1.5 gb ram, android os 6.0,
internal storage 8 gb, this mobile is 4g so you can use any 4g sim in this. sim type is micro, battery capacity is 2600mAh.
I am little unhappy with the internal storage of this mobile which is just 8gb, so you wont be able to install bigger apps or games on your mobile if they install in your mobiles internal storage.
so overall this mobile is a good choice to but you need to buy an external storage( memory card) then its all fine.
you have three colour choices gold, silver and black.
you can buy this mobile on any online shopping site and it will be soon available in the market also.
