Sony J6 was my second mobile, bought 8 months back. Compared to my old Motorola T300, this phone is like driving a Zen after having driven a truck. Its extremely light and an equally good finish. When I bought this mobile, I had to choose b/w Nokia 3310 and Sony J6, because both the sets were available for the same price. I feel Nokia is charging a premium for its brand, which is kind not justified and not worth the extra money. One may feel cheated with the kind of battery Nokia is providing with the 3310.
I just couldnot resist the looks of this phone. When you switch on this mobile, it opens with a user friendly menu, all driven by a single roller.
The ring tones are also a treat to the ears, unlike with Nokia, which has the normal ring tones only. The battery life in my case is 4-5 days as Im not a heavy user of the phone.
If your budget is approximately Rs 5000, just like a lot of people including myself, this phone certainly makes a lot of sense.
