I started using it recently and find it's okay. I do have one question though. I use a task killer to get rid of unnecessary apps from memory. Unless I'm looking to move some files, this would include Airdroid. The task killer does its thing okay, then five seconds later, I hear a notification ping, and there's Airdroid back in memory. I checked the settings, and have open at Startup switched to off, but it still keeps showing up. It's irritating me so much I'm on the verge of uninstalling it. Maybe it does no harm, but if I'm not using it, it has no need to be in memory. Is this supposed to happen, or am I just missing something?
