I only have five apps and cannot get the new software update b/c I need 550mb to be removed. I've tried removing apps, but I don't know how to remove/delete photos and or music from my watch to get the additional memory i need to update. I've looked online but have found nothing that helps.
To delete several pictures, it saves some tapping if you first mark the ones to delete. This is done by either a long press on a picture or, from the overview page in Gallery, tap on the 3 dots.
From my menory (at least in earlier firmwares) the "Factory Reset" is not a real factory reset in that it doesn't delete the pictures. (It only restores the 3 default graphic files that I always remove. This is on my Galaxy Watch first gen.)
