XIAOMI says it have fast charging support but I missed it. second xiaomi says it have finger scan applock but also it facility is not seen in redmi note 3.
Finally it support 2sims & sd card but Costumer use only 2sims or 1sim & sd .I am using the device & believe me its not that bad like in all these comments. Software updates will remove all known probs. The best thing is xiaomi devices r fixable and their forum is superb.only thing I worry is about internal memory. Better.
