Excellent camera quality, best sound Dolby atmos but 2 GB ram is not up to the point only 800 mb ram is free on startup. Hang up with low load games like stick cricket, candy crush, 8 ball pool. Battery backup not up to the point but last a day at moderate usage, touch problem faced by me & many of my frnds. Brightness differ itself when set on manual mode.
Prefer mi 4i over this.I had also got replaced k3 by mi 4i.it is quite good expandable memory is the only issue
