To be honest right now I am writing this review on my samsung j2.i love this Model and and its colour, mine is golden in colour.It has great features and functions with an affordable price.Its been more than 5 months now since I bhought this product and till now I didnt have any major encounter with lag and hang the feature I like the most is that this phone has its own cleaner u can find it on smart manager.And the two major features that I love is smart manager and data saving mode very useful and easy to understand and operate Moreover it provides updates time to time and some updates bring great features like the update before this current update introduced S-Bike Mode. So guys I made my choice and I am excited what the next update will be.almost forgot to inform that it supports 4g very well and nowadays sim operators are giving free 4g data on new 4g sim.I enjoyed my 4g free data which was 9GB 3g/4g on Airtel 4g sim.Hope it helped you.?
