For quite awhile now I've been randomly getting apps that I attempt to install or update give me the "cannot install on usb or sd card" message. Its really starting to get irratating. I remember awhile ago coming across how to fix it, but at that time it hadn't ever started it yet. Now after looking and looking I saw someone mention a solution if you have a regular computer to use your card in, etc., however can't seem to find any of the solutions to fix it on your phone (I don't have any computer access). Could ANYone please help me with how to fix it?! ? Thank you for any/all assistance!
