About two or three weeks ago, I started getting a flashing icon in the corner of my screen every time I turn on the screen. It flashes a few times and then disappears. I've tried google for answers, but everybody else simply describes the REPLACEMENT of app icons. This is actually behind the app icons. It looks like a gear with a little blue circle in it. Unfortunately, I've started to notice my apps crashing too. I've looked through all of my apps several times and can't think of what it might be. The only thing I've installed recently is Juice Defender (life saver, if you've never tried it). Has anyone seen this? Any ideas? Thanks, in advance!
