.png Vs .jpg

Please specify what you mean by “device”. Thx.

Phone or tablet, I don't know for certain how iOS vs Android caches their files but if the OP is seeing png files, I would imagine it's created in the Fly app and is on the phone or tablet that is being used.

Maybe the OP will research it ... seems no one can say with confidence.
That said the actual images will be DNG and/or jpeg.
