While Android 1.0 was missing a lot of features we depend on in our day-to-day lives in 2018, the first commercial iteration of the operating system was pretty robust with the smartphone basics. No, it didn’t have a native video player or stereo Bluetooth, and it didn’t even have a “treat” moniker to differentiate it from future versions (that came with Android 1.5 Cupcake in April of 2009). But it had a lot more than you would expect.
Android "Pie" (codenamed Android P during development) is the ninth major update and the 16th version of the Android operating system. Android "P" was officially released on August 6, 2018.  ( source: Android Authority; Wikipedia)
