move all apps you can to your sd card and erase your messages and mine usually goes away, if it dont, try restarting your phone
Same problem I am having. I have the apps that can be moved to the SD card moved. I;ve deleted my messages. I've restarted many times. The fact is that it seems like daily I have less and less memory to use. I've deleted many apps that I've had before I began getting the error messages.
Does my phone work similar to an older computer hardrive, where I need to defrag, or in this case, hard reset, to reclaim memory or is this a phone defect?
