This is the best android smartphone at this range.
I have been using this phone since 15 days and I havent seen any lag in the phone.
I played, browsed, listened music watched movies, checked all the sensors and everything worked absolutely fine.
Only one problem I found was that loudness of speakers is just below average.
Otherwise everything was fine.
Its battery can easily last more than one typical working day.
The thing I loved the most was its user interface, because it works on MIUI8.0.
So those who have their budget around Rs 10000 - 15000 can buy this phone
