Just received my new Co-Star today and went through a couple of rounds of updates to get it current. I found a couple reviews/forum posts that have some really nifty tips/tricks but here's the problem. EVERY app they reference is listed as "not compatible" in the Google Play Store. I tried installing Dropbox via the APK; it installs but crashes every time. DO I have a defective unit or did a recent update totally break this device?
