So i have have the Droid 3, and for the past couple of weeks my phone sometimes looks for my SD card even though i don't have one. Like, apps wont work because they are looking for my SD card that doesn't exist. And when i look in the storage area under settings, the internal storage says information unavailable. When i reboot my phone everything works fine again, but then after a while it does the same thing, trying to look for a SD card that doesn't exist. Why is this happening and how do i fix it?
