Just got this new phone and after a day of playing with it, it keeps saying " you dont have enough space" - every once in awhile. I currently am using 66% of my storage (15 gb / 22.83 gb) and the ram is at 68% so I dont know what it's talking about. When i'm randomly using the phone, that messsage will pop up for a second, then go away. And sometimes when I am downloading things on whatsapp or sending files, it will say that too. why??
