Profile images viewed in the grid view sometimes show more of the image composition compared to when viewed larger. The grid view is representing images in a square one-to-one ratio thumbnail appearance. But, when viewing the image larger, most smartphone screens are taller than wide, and therefore images submitted as 1028p x 1028p end up getting cropped. As far as I know, you are not able to drag to reposition, change the scale/zoom, or use multi-touch gestures like pinch to zoom, etc.

It seems an app that almost relies on images; the overall implementation could be more elegant. Allow higher resolution images, use of multi-touch gestures, figure out the aspect ratio issue mentioned earlier, and maybe use artificial intelligence to evaluate images for quality, or even composition.
