I noticed my Droid Pen turning on, even though I didnt shut it off. Looked at it and it was on my home screen, and at top left corner was a yellow triangle with an exclamation point and it said low space. Then 2 or 3 force close boxes popped up. I closed them, then phone shut off, turned back on and did same thing. I closed the force close boxes phone shhut off and now it wont turn on fully. It goes to the Droid screen then to the red X, then freezes and goes back to Droid screen and repeats itself.. Please help!
