Surprise: Only 2.3% of Android users are using Android M
Google released the Android M ( 6.0 ) in June last year, but only limited percent of the users got the update, thanks to the companies. Even though Google is actually good at giving updates to its Nexus devices, the same thing cannot be said for other companies, especially for Samsung who gave the 6.0 update the Note 5 in the previous weeks.
Unlike Apple, Google is unable to reach to the high percentages with their new operating systems, so that after several months, Android Marshmellow reached to only 2.3% of Android users. It is not because Google, but because of other Android phone makers. Cough* Samsung Cough*. For example, Samsung is terrible at giving updates to its phones.
