I have an LG Optimus V with Androir 2.2.1 stock. I've been having problems where apps that I have disappear. The homepage icons are replaced with the Market icon while the label remains. Generally, I can reload the app and its configuration data (like game high score) is still available. I reviewed earlier posts and the idea that the memory card isn't being mounted doesn't make sense, given that the card has been in for days and it is as much as 4 hours since the phone was turned back on. Any other ideas ?
