I have porchesed this mobile befor three month. Its good mobile. Battry backup is much better and camera resolution is good. 64GB veriant but usebal 54GB why I dont know. Also no any app ranning thet time onle 1.9GbB ram free this less then 50% . This all are system proble but one other problem is its tafen glass. No any glass complety fit on this mobile cos this mobiile has 2.0 coved disply. When I parchesh this mobile the android system 6.1( marsmello) and miui 8.2.5.0 but after updeting new system is android 7.0( nogat) . And miui 8.5.4.0. this is a great mobile on this price range. Sum pepal says xeaomi service is poor but I have alrady gon two time service sent aind its good experiance for me
