When I look at Settings -> SD card & phone storage: SD card has the total space of 14.83GB, available space of 14.83GB. (That means the phone has not used the external SD card at all.) Internal memory has the total space of 4.00GB, and the available space of 1.78GB. Internal storage has the available space of 1.10GB. When I look at Settings -> Applications -> Manage applications: On "SD card", i.e., the internal SD card, it has 2.2GB used and 1.8GB free. (That means the phone has been using the 4GB internal SD card instead of the 16GB external SD card for apps and data.) Seems like LG Esteem just does not use the external SD card at all. A lot of other owners have also had the same problem, but no one has gotten a real solution to the problem yet: http://androidforums.com/lg-esteem/532114-sdcard-shows-4gb-but-should-16gb.html http://androidforums.com/lg-esteem/430770-lg-esteem-storage-capacity.html http://androidforums.com/lg-esteem/537660-cant-unmount-format-my-new-sd-card.html http://androidforums.com/lg-esteem/482628-sd-card-not-working.html http://androidforums.com/lg-esteem/474555-yet-another-question-about-using-external-sdcard.html I want to move apps to external SD card. I've already tried formatting, reformatting, inserting, removing, re-inserting, mounting, unmounting, remounting -- all of them seem to have affected only the internal SD card. LG Esteem simply does not want to touch the external SD card. Why doesn't the phone use external SD card?
