First of all I want to say that This is a born masterpiece.and it proved that the simple looking Redmi 3s prime is not so simple.it is a fully loaded phone from inside.
It is the best budget phone under 9000/- in India.
I am almost impressed at every part of its. Its Design, Sensors, Display, Memory, Processor, GPU, Chipset, Camera, Flash, IR Blaster, Battery, Sound/audio.all are pretty impressive.
First of all, The design is pretty awesome like its Big Brother Redmi Note 3. Simply the fornt of 3s & 3s Prime are small but looks are the same with Redmi Note 3. In the rear side, You can notice the difference.
Out Component position:-
As previous Mi devices you will notice that There is no home press button like other brands(samsung, apple, meizu etc.). There are 3 touch buttons on the front panel of phone.then the HD 720p Display, and then the proximity, light sensor, Front camera, Earpiece comes at the top.
It is having the mic & charger port on the down edge and on the top edge you will see the IR Blaster and the headphone jack.
Going to the back side first of all you can notice the camera and flash are on top-left edge.
then you can find the Fingerprint sensor.and on the lower side you will see the MI branding and the loudspeaker vent.
