Recently Motorola rolled out android 6 update for it flagship moto x style. Making it the first mobile brand to give the pure android 6 experience next to the nexus.
Though moto gives a near raw android experience it also packs in a little of moto goodies which some people may not like but all in all even moto has to tinker the raw android rom. Hence the delay. But all its promised devices will get updated till first quarter of 2016.
The new update will improve the battery life and hopefully solve some of the heating issues with its devices.
The regular and early updates on moto along with good hardware make it unique and stands apart from other brands.
It's only a matter of time until all its devices taste the marshmallow. U can check out the details about ur device HERE
