The Idol 3 was a solid phone when it came out last year, but Alcatel quickly fell behind on Android updates. As of now, this phone is still running 5.0.2, but that's about to change. The Marshmallow update is going to start hitting devices today. Like they say, better late than never.
We’re excited to share that Android M is available for unlocked IDOL 3 devices beginning today!https://t.co/Ml3dpOtH75

This will be a big update for the Idol 3, as it's jumping all the way from 5.0 to 6.0. Most phones with Marshmallow updates are starting at 5.1. That will mean a lot of security patches, better memory management, granular permissions, Google Now on Tap, and more.
The OTA is supposed to start today, but none of the Idol 3s on the team are seeing it yet. The video included with the tweet above might explain that. I don't have a marshmallow handy to smash on the phone. Whenever the update does happen (Alcatel says today), it is only for the unlocked Idol 3. That's probably the vast majority of the devices in existence. There was also a version of the Idol 3 on Cricket, and that update is still in the works.
