Before 1 month back I bought mi 4 phone. At that time I was not thinking about review. Because you can know about the phone after some days. Some of the phone will be good in starting days. Then after problem arives. But I am giving 5 star to mi 4 after one month. Because this is the one of the top most phone at present which is giving best all rounder performance. Means everything works fine in this mobile after installing soany apps in the mobile. It will not hanged. Battery back up is also very good. Resolution, camera quality design, security, everything is good. I am writing about this phone like this means you can think that this phone is worth 100% for your money. Thank you Mi.
