The Xiaomi Mi A3 is quite distinctive when compared to the Redmi series smartphones that we have recently seen from Xiaomi and a huge improvement over its predecessor the Mi A2. The first thing that you notice about the Mi A3 is its narrow form factor that makes the handset ideal for one-handed operations, especially if you have relatively smaller hands. Not may handsets offer a narrow frame anymore so those who like themselves a petite smartphone, may like to use the Mi A3.
