This might be quite obvious to most, but I only just worked out how to get to the Apps and Widgets screen on the galaxy tab 2 (Android 4.0 ICS).
On your home screen, on the top right corner there are boxes that represent your workspaces. Press this to bring up your Apps / Widgets. Which is the interface I find the most convient for launching apps.
I don’t what it is about touch devices and their operating systems, but manufacturers seem to insist that everything is intuitive and you’ll just “know” what to do?
