Xiaomi is the best company I thought in making mobiles it gives all the features of high range mobile to this phone and I am a big fan of my phones and red 3s built quality is very good
Octa-core processor in this price very awesome
It also has a fingerprint sensor no other companies give fingerprint in this range
The camera is also good. And there is no lag in multitasking, screen clarity is too good, this mobile is also infrared support you can control TV, Ac, setup box etc. So buy this phone without any hesitation.
