I have an LG Ally. Continually I receive messages saying a text could not be delivered because my text memory is full, or I have no more phone storage left. I go through, delete all the texts, delete pictures, and have tried to delete unwanted apps but cannot because the uninstall tab is disabled. I've turned the phone off, removed the battery, etc. and sometimes this works (after I've deleted a bunch of stuff) but it doesn't always work. Soon afterwards I get these messages again and cannot receive texts. What's the fix for this?
