Every time I open up my gallery I get a folder called cache with four black, empty pictures inside. It doesn't matter how many times I delete it, every time I open the gallery back up, there they are. Does anyone have a clue as to what's causing this and what I can do to get it to stop? My sanity is at it's breaking point! Thank you! EDIT: I got it on stock Cyanogen 18.104.22.168 and am getting it as well with smoked glass-esque.
