This phone is the real game winner of this year.The main reason for I loved this beast is this phone packed with 3gb of ram, 3300 mah battery, Dolby Atmos front facing speakers, fingerprint scanner and especially this phone can use with Virtual Reality( VR) headset. The phone also compete with Letv Le1s and upcoming phome redmi note 3 but they are failed because they dont have expandable memory card slot. Othered points dont bothered me because I used lenovo k3 note and I am satisfied with that phone. This phone all specs are improved compared to k3 note so this will steal the light from other phones.
So my opinion is real beast in this price range. For 12k you will get all technology used nowadays.
