October once again saw the majority of BlackBerry 10 users running OS 10.2.1 on their phones. This is mainly due to BlackBerry not officially releasing OS 10.3.0 for any users besides those on the Passport. While the percentage of users on the newest OS (4.3% on Pixelated and 15.1% on Stuff I Need) is higher than the percentage of Passport users, most people (including myself) seem to be waiting for an official update from BlackBerry.
This data was collected by BlackBerry World for downloads of the free strategy game Pixelated and the free checklist app Stuff I Need. Data shown on the chart is from the beginning of October 2013 through the end of October 2014.
