I have been using this mobile for more than a month and I think now I am eligible to write a review.
While calling on the other side people cant hear my voice for 4-5 second. But I can hear them properly. It happens every alternate 2-3 min while on call. And guys its not a SIM network issue. It started when I am using this phone and for every call. Again while calling other side cant hear my voice as sound is very low. Its a definate bug with the dual mic concept. This phone have noise cancellation using dual mic and that might be the issue. And mic cancelling the original voice also.
Well camera is out standing comparing Redmi Note 3 ( My brother have it) . Selfie is just lovely. well it actually modify your skin tone and looks prettier.
Light gaming is ok. I have played asphalt 8.
Display quality is so bright.
Battery back is good for usage. Last a day. Redmi phones have much more battery life. But charging is very quick. 1 hour 15 min to charge from 0 - 100.
Forget 1 thing. No heating issues. While havvy downloading or mass copying device warms a bit. But guys its pretty normal for a smart phone.
