I have a message in the top taskbar (?) that says "Low on space: Phone storage space is getting low." Touching this brings me to a whole list of applications and the memory they are using. However, these levels are no longer displaying. In fact, my droid has been very buggy in the last 12 hours. The calendar just now loads, as do some other programs. Is this a memory issue? I tried going to each of the programs in the list described above and selecting "Clear Cache," but this literally does nothing. Neither did clearing the browser cache, cookies, and history work. What's going on?
