Very weird issue, over 24 GBs of my storage is being taken up by these "other" files. I can't seem to figure out the issue. I looked at the hidden files and sorted apps by size, but I can't find anything that adds up to 24 GBs. After googling, this seems to be a samsung wide issue. Can someone help?
When you deleted your picture from your Gallery did you remove them from the trash?
Give these steps a try: Go to gallery, tap the 3 dots in the top right corner, and tap on trash
Have you tried to clear the cache partition on the phone yet? You can do so by following these steps.
You can try installing a third party file manager and have it display the folders sorted by size. That may help you figure out what app or file id using so much storage. I use Cx file manager and use the 'analyze function to help clean up files and folders. It can also help clean out some of the app caches too.
