The BlackBerry PlayBook OS v18.104.22.1688 contains many updates including:
- Browser enhancements to address performance with some websites
- Improvements to support Android apps
- Optimizations to Video Chat, PIM and BlackBerry Bridge applications
- And much more!
User should see a notification to update or simply go to options and click on software updates. The Update is about 355 MB for me, so it is a substantial download.
