Samsung Galaxy J2 is a good choice with Android OS, v5.1.1(Lollipop) operating system, internal storage 8 GB, 1 GB RAM, 5 MP camera . I am a fan of photography I cant spend too much money for dslr but this phone had completed my needs with auto focus lens. it have long battery life with 2000 MAH battery up to 10 hour talk time and and about 60 hour standing mode. And also with low price about 1500/Rs. I have used it for six month and I feel comfortable with this
