A while ago I put Go launcher on my Bionic but every time the screen went black and I woke it back up it would be on the motoblur. I forgot about using a different launcher until yesterday when I ahd 7 hours to kill sitting in an airport. I put Go Launcher back on and before I modified it in any way I tested to make sure it would stay as the default launcher and it worked. I then spent about 5 hours setting up folders with apps, a theme, and just generally making it a lot cooler. After boarding the plane I had to turn it off for a bit. When I turned it back on it still had Go Launcher but everything i had set up was gone. Why would this happen? I took it off and the original launcher was exactly as I had left it. I do want to use Go launcher but before I spend the time setting it up again I want to make sure it stays. My question I guess is what caused this mishap and how do I avoid it? I appreciate any help.
