Now that android m has started rolling to users around the world, not only nexus but even lg g4 is being upgraded right now, it bugs me that we are still stuck with a 32 bit os. We have been promised to get lollipop long time ago but nothing came of it. I wouldn't even have bought my redmi 2 pro if I thought it was doomed to remain on kitkat. Is there any realistic chance we ever see a stable 64 bit miui for our device? I'll be happy with lollipop but marshmallow would be even greater.
