While the percentage of BlackBerry 10 users on the newest OS continued to increase in April, the adoption rate has slowed down significantly as a number of carriers continue to drag their heels on the rollout. 59.9% of Pixelated users, and 70.5% of Stuff I Need users were running OS 10.3 in the past month. So far this has been the slowest rollout for a new BlackBerry operating system since the launch of OS 7 in 2011.
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 April 2014 through the end of April 2015.
