I just got a unit. I've been trying to verify the authenticity of my phone but there's two IMEI numbers and I get a "IMEI doesn't exist" like message when I try either one. Should I be suspecting something?

I was trying out this link: http://www.mi.com/verify/#imei_en
Not sure if it's the correct one to use for Malaysian handsets.

Anybody have any experiences with this phone and AUX cables? I have to plug cables into my unit and car stereo in a certain order before it finally plays through my car stereo.

Huh, I don't have a bluetooth set to try, maybe I will when I get the chance next time.

I usually fire up Spotify, play it through loudspeaker, connect AUX cable to headphone jack, wait till the phone transfers sound to cable before plugging the other end into my car stereo. It works most of the time but I think it's a bug.

What's the preferred method of rooting whilst preserving OTA? I've gone the cofface TWRP recovery then SuperSU zip route.
