So yesterday i was checking something on facebook, and after a while i got a notification saying ( internal storage is full ) or something similar. was this because of facebook? and i never received a message like that so it was really strange. also im expecting some important text message from someone and i dont want to sound paranoic or something but ill ask anyway: is it possible that this person sent me a message and i couldnt receive because of my low memory or something? just asking.
