I keep getting a notification all the time on my status bar and it read "low on space internal phone storage is getting low" there is a red sim card icon before the text. The red sim card icon stays in my status bar until I remove an app, when the red icon is there I cannot receive text messages as it blocks them coming through, it says "Message memory full, incoming rejected. Memory full" . When I go to my task manager it tells me I am using 165mb out of 181mb internal storage, surely that shouldn't be a problem? Even if I download an app that is SD enabled I still get that message/icon. Can any help or am I doing something wrong? It's really starting to annoy me now.
