A Galaxy S26+ comes in 256 GB and 512 GB sizes with no card slot, and a phone that is nearly full usually reached that point through photos and videos at the 50 MP camera's size, plus a few large games. Samsung's Device care shows what uses the storage: Settings, Battery and device care, Storage, with categories for images, videos, apps, documents and system. The quickest wins are in the Gallery's Recycle bin, which keeps deleted photos for thirty days, the Downloads folder, large videos found by sorting by size in My Files, and cached data in apps. Cloud storage solves the real problem: Samsung Cloud, Google Photos or OneDrive can back photos up and then free the phone's copy. Offload games you rarely play.
A restart after a big update clears temporary system data. Keep a few gigabytes free, because updates and the camera need room, and a full phone slows and crashes apps. The S26+ also records 8K and 4K 60 video, which fills storage fast: a single minute of 8K can take hundreds of megabytes, so lowering the video resolution in the camera settings for everyday clips saves a lot over a year. The Gallery can also store photos in a space-saving format, and sorting the Gallery by size shows the biggest items first.
Note that the S26+ keeps Samsung's AI features' model data on the phone, and some of it is optional: in Settings, Galaxy AI you can see downloaded language packs and remove those you do not use, which frees space.
