Pros:
It is a true value for money the specs it is offering will not be in a phone that is twice the price of this phone.
Can play all low to mid level games like temple run, candy crush, etc without any lag.
Can surf web at good speeds with no lag.
The looks are an ultimate killer it is a very pretty phone according to my view.
Front camera will give u pretty good snaps and back camera is way above than its league even in low lights due to excellent flash.
Highly customizable User Interface, Use themes and other features which are given by MI itself.
Real butter smooth touch.
Sound quality is also good. Trust me use nice earphones and this phone will give you decent enough music experience. Also many effects to suit various earphones.
Battery backup is real nice. If you dont turn on wifi or mobile data or gps it can give backup to a stretch of two days. With calculated use of such services you can easily make it work for full one day(24+ hours). But if you are a net freak expect it to drain within 10-12 hours on 2g and 6-8 hours on 3g.
Cons:
Heating issue. Yes but after installing the updates from MIUI it is highly reduced. I would suggest if u constantly keep you wifi and gps and all such thing on, dont waste your money, add a few more bucks and buy a better phone. But if you are a precise user of such services like 3-4 times in a day and only when needed like me, this phone is more than sufficient with little or no heating.
Memory management is very poor not even two big apps can be opened simultaneously in this phone.
Rest I did not find any cons . Please again dont compare it with camera of Lumia series, or sound quality of Sony. For God damn it is 6k budget smartphone. If u want quality add some more bucks and better buy high end phones.
Conclusion:
I am very much satisfied with this phone.
No technical issues faced at all.
For any person who is looking for a simple smartphone with normal genuine uses and in short of money can easily bet on this little monster. Trust me you wont be disappointed but if you are planning to make a hell use out of it, stay away sooner or later you will abuse this phone.
PS: Please mark accordingly if you genuinely felt helped with my review both in finalizing or cancelling your plan to buy this phone.
