Today I was on my computer and I had my phone (Samsung Galaxy S2 X) sitting beside me. All of a sudden the screen on the phone came on and instead of it showing the lock screen, it went directly to the home screen and a little message appeared at the bottom saying "Sending...". This happened a couple more times and then stopped.
I have ran both a AVG and avast! virus scan of my phone and both came up empty.
I'm wondering if I should be worried if something like this happened or is it something else? What I don't understand is how it just went straight to the home screen without having to unlock it. There's nothing in my text messages or emails to suggest it was being used for spamming. My guess is that it was just an app sending usage statistics or something? Any ideas?
