Android keeps warning that storage is running out, the camera refuses to save, and every app update fails. Somewhere in the Settings menus is a list of exactly what is taking the space, and it is rarely what people expect.
Open Settings › Storage, start with the largest category, and remove things you can download again before anything else. Clear an app’s cache before you ever clear its storage, archive apps instead of uninstalling them where you can, and copy photos and videos off the phone before deleting them.
Free tool: the video storage calculator shows how much space your videos take at each camera setting and what switching settings would save.
Find your phone’s storage screen
The path depends on the brand:
| Phone | Path |
|---|---|
| Google Pixel and most Android phones | Settings › Storage |
| Samsung Galaxy | Settings › Battery and device care › Storage (older models: Device care) |
| Other brands | Search Settings for Storage |
Note the free space and the two largest categories before you start. The Android storage screen covers the phone only. A full Google Account is a separate limit, handled in the Google cloud storage guide.
Use the built-in cleanup tools first
Android already includes the tools that cleaner apps charge for.
Files by Google (built into Pixel phones and free on others): tap Menu › Clean. You get cards for junk files, duplicate files, large files, old screenshots and unused apps. Junk files are temporary app files, and clearing them leaves app settings alone. Google warns that files cleared here are permanently deleted, so open the duplicate and large-file lists before you confirm (Files by Google Help).
Samsung Storage screen: under Battery and device care › Storage you will find Recycle bin, Duplicate files, Large files and Unused apps. Each opens a list you can review item by item (Samsung).
On Samsung, the Memory › Clean now button closes background apps. It frees working memory, not storage space.
Clear cache before you clear storage
Every Android app has two buttons that look alike and do very different things.
Google’s own advice is to try deleting data inside the app before using Clear storage (Google). There is no button that clears every app’s cache at once on most phones; you work app by app, starting with the largest.
Clear space in this order
Offline downloads
Open each streaming, music, podcast and map app and remove finished downloads from its Downloads or Library screen. They come back when you are on Wi-Fi.
Downloads folder and large files
Open Files › Downloads (or My Files › Downloads on Samsung). Sort by size. Open unfamiliar files before deleting; tickets, receipts and forms often sit here with vague names. The Large files card in Files by Google finds big videos and archives anywhere on the phone.
Large videos
Copy them to a computer, drive or another cloud service and play the copy before deleting the phone version. The large video guide covers formats and upload limits. Then empty the gallery’s Trash or Recycle bin; deleted files keep using space until it is emptied.
Unused apps: archive instead of uninstall
Recent Android versions can archive an app. Archiving removes the app’s software, permissions and temporary files but keeps your data and the icon. Tap the icon later and the app reinstalls where you left off, as long as it is still on Google Play (Google).
To let the phone do this for you: open the Play Store, tap your profile photo, then Settings › General, and turn on Automatically archive apps. To protect a rarely used app, such as an authenticator, from being archived, go to Settings › Apps, choose it and turn off Manage app if unused.
Uninstalling removes the app’s local data. Do that only for apps you are finished with, and cancel any subscription separately in Google Play; the app review guide explains what to check.
Photos
In Google Photos, wait for backup to finish, then tap your profile photo and Free up space. This removes phone copies of items already backed up. Deleting a backed-up photo inside Google Photos removes it from the cloud too. The photo backup guide shows how to make an independent copy first.
Storage is still full
- Give the storage screen a few minutes to recalculate, then reopen it.
- Empty the trash in Gallery, Google Photos, Files and My Files.
- Check WhatsApp separately with the WhatsApp storage guide. Its media folders can be several gigabytes.
- If System is the largest category, that space belongs to Android itself. Install pending updates and restart; a phone maker’s service center can help if it keeps growing.
- If your phone takes a microSD card, move photos and videos there through the camera or gallery settings.
Skip “phone booster” and cleaner apps from the Play Store. They duplicate what Files by Google and Samsung Storage already do and often add ads.
Keep it from filling again
Turn on automatic app archiving, set Google Photos to back up over Wi-Fi, and run the Files by Google Clean cards once a month.
