Android M Release Date
The rest of the Android M feature details are murky though Android sites have been able to cobble together a few potental features. At the end of the year, a report from Reuters also highlighted some possible Android M features. It also discussed a potential Android M release date.
In addition to talking about Google's ambitious plans for Android Auto and a tie-in with Android M, Reuters' sources also indicated that the Android M release wasn't expected for a year or so. The report came out in December so it means that we could (and should) see an Android M release in a familiar release window.
Google tends to release its new Android software alongside Nexus hardware in the fall during the holiday shopping season. November is the month that it likes to use. And while this report doesn't out a specific date, the window lines up with Google's release protocol.
