I have purchased Mi A3 when I was in 11th now I am in engineering 2nd year till now the mobile is in good condition. I have purchased 4gb ram and 6b gb rom varient. It comes with 4035 mah battery and its front camera is of 32 mp and back camera is of 48 mp. I liked the durability of mobile it has fallen many times and from 5 feet height but nothing has happened to my mobile. The only problem is of battery backup after 18 months. Excluding the battery backup problem there is no other problem I have faced. The mobile is best for that price range.
