M for marshmallow - a lot of whipped up froth and not much substance.
Android Lollipop is not yet stable then Android M is on it's way. Hope that Android M clears all the bugs and will be much more stable and Android L. Anyways the new features are nice. HURRY UP AND GIVE US A MUCH MORE STABLE VERSION! :)
M stands for Mango this time, already Vodafone IN on home screen so seems major testing etc are done in India
Google has lost the plot completely. No real progress since KitKat. Lollipop still v bug ridden. :(
M for Mango. To End Users may be next year in Q2. Till then wait and be excited as usual.
There is experimental multiple window support among other things hidden in developer options.
When will 10% of Android phones run this version - 2020 ?
Useless how a year or so after release of Lollipop, only 10% of Android phones are running 5.0 or greater, and not even optimally - a number of issues still being sorted out.
