Does this happen to anyone with an iPhone 6s?

Sometimes when I try to look at my pictures this circle in the corner pops up and it needs to load or something. Usually it loads but right now it doesn’t want to. You see how it’s an empty circle well it starts filling up white once in Awhile. Also they are blurry till it fills the circle.

I thought it’ll work if I pressed edit but it just showed “downloading”
