Since I am using 1 year, it’s one of the best best mobile I am using so far, till now I don’t have any problems with this mobile, gud picture quality, and mi updated it’s versions thoroughly which is the best thing in mi mobiles, easily update, but I have slightly disappointed with several times it has been over heated, especially in when you charging, good battery backup, ram speed is also gud, best mobile for middle class we don’t buy other branded mobiles at this and same configuration. Worthy buying.
