How to free storage besides clearing up cache memory I have a Samsung galaxy smart phone. Whenever I download apps such as,Ubber and Facebook it tells me that my storage is full. I have cleared up cache memory but still there is no difference. What can I do?
Disk usage - view whats really eating up your storage

SD maid - file cleaner

Files Go - by google - leave it installed and it will automatically remind you what unused files to delete

Google Photos - backup every photo and select free up storage to delete already backed up images and videos
