I have an awesome experience with this phone since I bought I got the gold version.
Redmi note 3 is best budget phone offers full hd display and figerprint scanner also and I unlocks with only fingerprint and it works everytime accuracy is 95%
Another key specification os it's battery, it has the best battery I have ever seen.performence is excellent it showing 73000 score on antutu bench mark means above average product .
It has some cons also the display not so strong enough because it has no protection in it.and it doesn't get android updates frequently.
In morning tha camera performs very well.i shoted many shots with it but in the night it performs badly. It has almost every sensor in it and the gyro sensor works blazingly.
It heated up too much while charging we need to use back cover in order to protect it from scratches and to hold.
I think this is the first smart phone has the snapdragon 650 processor the processor can perform really well compitates with the latest processors.
Finally this is the best budget smartphone I ever get.and offers best battery backup.
