I will give the details about what I feel for the following topics-
Screen- the resolution is really good.the screen can be viewed from sides also.
RAM management- it is not that great, xiaomi should improve it through the updates.
sound- the speaker is a decent one, produces good quality music.
camera- the front camera is a good one for selfies whereas the rear camera is average, not that good as compared to a 16 MP shooter.
style & design- the style is pretty awesome with metallic body at the back n plastic in the edges.
features- there r alot of special features like the dual led flash, finger print scanner, IR Blaster.
durability- the phone is a hard one though we dont know about the glass quality. it is a good phone for heavy usage.
battery- the 4000 mAh battery is the best thing in the phone. it gives me almost 5 and a hlf hours after heavy usage and sometimes 7-8 hours also.
easy to use- the miui is the best ui I guess and the way they handle the updates every week in developer ROM and every 2-3 weeks there after. The themes are awesome and tehy are all free to download.
value for money- I will give 9.5 out of 10.
pros- good battery, finger print scanner, IR Blaster
cons- average camera, hybrid sim slots.
