Good day,
after playing around with the Vodafone 845 (Android 2.1) icons positions I ended up with additional empty home-screens (or are they desktops, not sure for the term). What is the proper way to remove those empty screens?
You can't with the default launcher. However, with a lot of home screen replacements you can define how many home screens to have. (Zeam, Go Launcher, and Launcher Pro do, for sure.)
Nicked from here:
Menu -> Edit. Click the red (-) button in the upper-right corner of the screens you want to delete. Use the [+] button at the bottom to add a new screen.
