A top Lenovo exec said he'd "bet a paycheck" that Motorola will be the third-biggest smartphone brand in 3 years, laying down a challenge to Apple and Samsung.
They'll need to lift their game on software updates for that to happen. Many of their handsets ship with an outdated version of Android, and they rarely see more than one major update.
This is what caused me to switch off Motorola. Their Moto Z phone with the magnet attachment thing was badass. But it was 2 major android versions behind, and was no longer receiving security updated by the third year I owned it.
Even if they are, it's a drop in the bucket. And I imagine they're less popular now than they were in the early days of Android, during the height of Cyanogen Mod, and others.
