Why is my Acer Iconia tablet freezing up?

Brent has an Acer Iconia tablet and it's starting to freeze up when watching movies. Leo says if you can update it to the latest version of Android, that would be a good idea. Another idea would be to go into backup/reset settings and restore it to the original settings. Sometimes that helps with issues by starting from scratch. Just make sure you have enough space.
