Lenovo a7000 was my first own smartphone so as it was my first phone I searched each and everything and after some research and careful observaions and comments from friends and families I finally choosed this mobile and now I am perfectly satisfied with it’s performance got an update of marshmallow but it is not supporting volte required for jio sim.
but remaining battery prformance speed all are completely satisfying so you can buy this phone without any doubt. go for it
