August saw the use of OS 10.3.x (specifically 10.3.2) continue to increase. There was actually a bit of a split in the data for this month as users of Pixelated were much quicker to upgrade than users of Stuff I Need. For Pixelated 91% of users were running OS 10.3 while the number was only 84.6% for Stuff I Need users.
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 August 2014 through the end of August 2015.
