If you’re looking to delete files from your Galaxy S5, there are a few different ways to go about it. The first option is to use the file manager on your phone. This will allow you to browse through all of the files and folders on your device, and then select the ones you want to delete. If you’d rather not use the file manager, you can also use the built-in deletion tool. This will allow you to select specific files and folders, and then delete them all at once. whichever method you choose, be sure to back up your files first in case something goes wrong! ..
