Its a good budget phone with some pros and cons. I will explain its pros ands cons briefly.
PROS:
1.) The external body metal design gives the feel of a flagship phone and give the best in hand feel. Although the phone is slightly heavy but its amazing weight distribution doesn't let you feel to the heaviness.
2.) Best camera at this price. Althougu night mode and wide angle camera are note that good. But still gives one of the best selfies and shots from rear camera too despite giving some warm colors sometimes. Video quality and slo-mo videos are awsome too.
3.) Ram management is great too.
4.) Phone never heats much while charging or playing pung too( although sometimes you get notification of frame drops) .
5.) 5020Mah battery is the real plus point for this phone. Easily lasts upto 24 hours even on very heavy usage.
CONS:
1.) Some phone gets rebooted itself after get hanged for 2 3 seconds.But this problem reduced to a very large extent after latest software update.
2.) Some inbuilt Chinese apps are in the phone.
3.) Lot of adds and vulgar adds in mi browser.
4.) Display is good but brightness is slightly less when used mobile outside in sunlight.
