Various apps are telling me that although an SD card is inserted it is not mounted. When I go to settings and press "mount SD card" a notification comes up that the SD card may be safely removed. This does not fix the problem. I have turned the phone off, ejected the SD card and re-inserted it and it still won't work.
Any advice or suggestions?
Yes. This is a replacement phone provided by Verizon after they were unable to fix a hardware problem with my original phone. The SD card worked fine in the original phone but will not work in this phone. I have formatted & re-formatted a number of times, but the phone still won't mount the card.
