+1 for Game Mode As others have mentioned, background processes can invoke the GC. On my development device, I used to have Taskiller installed for the occasional Kill-All but I realized that it would regularly invoke the GC about once a minute. I think the Taskiller widget was causing this to happen, but it's ridiculous to think that a program I installed to manage memory/lag was actually slowing my device down.
