Now days! Samsung approach its quality and brand values both. we consider a good mobile phone by following aspects.
1) Good processor.
2) Good Ram and Rom.
3) Quality of display ( Resolution)
4) Camera clarity.
5) Sound.
6) And price. Samsung not so much cheap but it is very reliable and faithful. Samsung Galaxy J2 - 6 is one of this, I really use this many times, no problem at all. 1.5 gb ram with very good processor. 8 mega pixels camera with front 5 mega pixels, Very smooth sound, And not at big cost.
personally I suggest you to buy it.
