My guess is right from their previous teaser at their Facebook page as Xiaomi Philippines will gonna bring here the Redmi 2 soon.
Some of the biggest differences of this device over the Redmi 1S is the Snapdragon 410 quad-core processor, lighter at 133 grams, LTE connectivity and a slightly bigger battery at 2,200 mAh battery. One concern in some fans here as they will brought the 1 GB RAM model here. Other countries have this device with 2 GB RAM.
No official info yet on release date but this has an official SRP of Php 5,999.
