I am sharing my personal experience on htc 616 which is the dual phone sim. but there is problem with this mobile that the sound and camera I didnt like of this phone. the picture quality is also too low. but the other mobile oh htc. didnt except these from htc.
The bigggest thing is the sound is also low. that didnt recognised.yes it is a user friendly product. but in my opinion I didnt purchase again htc phone because what we need in our mobile is nothing in this mobile. as htc himself is the brand. but this time it proves me wrong. no more features that we love in other phones. and no good sound reception. looking wise ok ok model. and value of money is nothing at all. because it is the ohone which we didnt buy again in future.
thank u!
