Wow this phone is amazing!
By Kevin Davidson | 16 May 2019
This is clearly the Best phone of 2019 Screen 10/10, performance 10/10, love the look 10/10. If common sense was the way of the world this would be phone of the year! In my opinion in real world applications this phone shines and for 500.00 USD half the price for better overall performance than any other flagship and if you disagree I would honestly have to say you do not make economical sense!I have not been impressed with a phone in along time! Way to go Xiaomi for building the best price to performance phone I have ever seen and to do it at absolutely not skimping out! Exceptional quality and performance! I would have to say phone of the year!

Mi9 is decent budget phone
By Anup Kumar Debnath | 27 Feb 2019
It is not a flagship anyway. High spec doesn't mean to be flagship now a days. More of a budget phone
