I've been with my Droid 4 for about a week, but it has slowed down for some reason. I'm suspecting that it's due to all those open apps, which I don't know how to close. How do you close all apps? Is there task manager? I come from the Windows Mobile world, and, as archaic as the OS was, it was very easy to bring up the task manager, just like in the Desktop Windows OS, and close any or all apps to reclaim memory and speed. I'm sure Android has something similar or probably something better.
