Back in the spring I had left my iPod on overnight one night. When I went to use it the next morning, the camera roll app was open, with a bunch of random pictures and videos of the ceiling (it had been lying face down on top of my laptop, which was turned on but the lid was shut). Safari was open as well, with two or three tabs open to websites I hadn't seen before. As if all of that wasn't weird enough, 3 GB of memory had disappeared, and deleting all of the pictures and videos of the ceiling barely freed up any memory. It was like that until a few days ago when the free space on my iPod went from 1.2 GB to 4.5. Has anyone else experienced anything like this or know what's going on? [spoiler]I'm still running iOS 9. Not sure if that's relevant or not.[/spoiler]
