I've 'freed up space' so that the actual photo storage should be entirely empty, yet my phone shows 0.92 gb of storage taken up. As far as I can tell, this has nothing to do with the images on my phone; I've checked in all the other folders and there's nothing that would indicate why this amount of space would be taken up by the app itself.
I've tried googling the problem, but all of the answers point to stories about how Photos stores your photos in the cloud, how that policy is changing, how to 'free up space' by uploading, etc.
I've done all that! And the app is still too huge.
Maybe it's got it's own hidden cache or something that I can clear? (I've already cleared the cache via the app management tools in settings.)
