Why is my phone storage full?
Last reviewed: September 23, 2026 · Markdown version
Look before you start deleting. In Files by Google, tap Menu and then Clean: at the top you find the device's used and available storage space, and the SD card's too if the phone has one. The same screen then names the usual culprits as cards — downloaded files, duplicate files, large files and old screenshots.
Start with the measurement
Google's help for that screen describes it exactly: open Files by Google, "Tap Menu and then Clean", and "At the top, you find the devices used and available storage space." It adds: "If your phone has an SD card, you also find the SD card's storage space." (Check storage space, read 23 September 2026) Knowing which of the two is full changes what you should do next. Without the app, Settings gives a similar view: "Tap Storage. Select a category." (Free up storage on your Android device, read 23 September 2026)
The usual culprits
- Downloaded files — the pile you never revisit. On its card, "tap Select files", then "At the bottom, tap Move x file(s) to Trash" (Delete downloaded files, read 23 September 2026).
- Duplicate files — the same file saved more than once. "The original file is marked with an "Original" badge. We recommend that you keep the original file." (Delete duplicate files, read 23 September 2026) How to work through them.
- Large files — its own card, with the same Select files step (Delete large files, read 23 September 2026).
- Old screenshots — free space "through the deletion of screenshots created or received more than 4 weeks ago" (Delete your screenshots, read 23 September 2026). Where they live.
All four end at the same place rather than at an immediate deletion: what you remove is moved to Trash, where "Files remain in Trash for 30 days and then are automatically deleted." The same page flags the exception on this screen — "Files deleted from "Junk files" card will be permanently deleted. They will not be moved to Trash." — and says the Trash feature "is available in Android R and will be rolled out in phases for other Android versions" (Move files to Trash & restore files, read 23 September 2026). So on the four cards above, the cost of being wrong is low, provided you notice within the month.
