I'm posting this for my girlfriend. She has a Samsung Transform and about a month ago, she has been having trouble installing applications on her phone. She tried to install the games "Prize Claw" and "Coin Dozer" and she gets an error message of "Cannot install app to usb device or SD Card." Now I don't know much about the Android OS or her phone but I can tell you that it's stock except for the updates that you can perform to the OS, Firmware, Sprint ID and PRL...or the standard updates that anybody can perform. Her SD Card is 90% free and her phone says that it has 35.44mb of internal memory left. a little help will do. Ed.
