Quick answer
The quickest fix is to check Settings > Storage to see what is taking up space, then clear app cache and remove large files you do not use. Move photos and videos to the cloud or a computer, and uninstall unnecessary apps. This frees up several gigabytes without losing important data.
How to recognize the problem
- Insufficient storage message when installing or updating
- Camera cannot save a new photo
- Apps close or do not work properly
- Phone is noticeably slower
- Storage shows almost full
Most common causes
Accumulated photos and videos
Camera and downloaded media take up the most space over time, especially 4K videos.
App cache
Social networks and browsers store temporary files that can take up several gigabytes.
Unnecessary apps and games
Installed games and apps you do not use still take up space, even when you do not open them.
Downloaded files and duplicates
The Downloads folder and various apps can contain old installation files and duplicate images.
System files and updates
Android and the manufacturer layer take up some space that cannot be freed, and updates temporarily require extra space.
Step-by-step fix
- 1
Check what is taking up space
Open
Settings > Storage(on some phonesMemory). At the top you will see total used space and a breakdown by category (images, video, apps, documents). Tap a category to see details and free up the largest items. - 2
Clear app cache
Go to
Settings > Apps, select the app using the most space (e.g. Chrome, Instagram, Facebook), thenStorage & cache > Clear cache. Do not clear app data unless you are willing to lose your login and saved content. - 3
Remove unnecessary apps and games
In
Settings > Appsreview the list and uninstall apps you do not use. Tap an app thenUninstall. If you cannot uninstall it, you can disable it (Disable) so it stops running in the background and using resources, but disabling alone does not free up the space the app occupies. - 4
Move photos and videos to the cloud
Open Google Photos, tap your profile picture and turn on
Backup. Wait for everything to sync and check in a browser at photos.google.com that the photos are really in the cloud, then in the app selectFree up spaceto remove local copies. Alternatively, connect the phone to a computer and manually copy the photo and video folders. - 5
Delete old downloaded files
Open the
Filesapp (orMy Files) and go toDownloads. Delete installation files (.apk), archives and documents you no longer use. Also check theWhatsApp > Mediafolder if you use WhatsApp, as it can accumulate many photos and videos. - 6
Use the Free up space option
Open the
Filesapp and in theCleanupsection review suggestions (cache, duplicates, large files). On some phones a similar option,Free up space, is inSettings > Device care > Storage. Review suggestions carefully before confirming deletion. - 7
Check large files and duplicates
In the
Filesapp look for a storage analysis option (on Samsung phonesStorage analysis) or sort files by size. Pay attention to videos larger than 100 MB and duplicate images. If you are not sure what is safe to delete, make a copy on a computer first. - 8
Clear Google Play services cache
Go to
Settings > Apps > Google Play services > Storage & cache > Clear cache. This can free up several hundred megabytes and will not affect your data or login. Do the same for theGoogle Play Storeapp if needed.
If nothing helps: advanced options
If there is still little space after cleaning, check whether the phone has a microSD card. If it does, in Settings > Storage select the card and move photos and music to it. Also, in Settings > Apps you can select Change for some apps and move them to the card. If the phone has no card, consider deleting old videos or moving them to a computer. For a long-term solution, make regular backups and use cloud storage. Avoid "cleaner" apps that promise miracles, as they often do nothing useful.
How to prevent it
- Turn on automatic backup of photos in Google Photos
- Regularly clear the cache of the apps you use most
- Uninstall apps you have not used for more than a month
- Occasionally check `Settings > Storage` and free up space in time
When to call a professional
If the phone still shows no space despite deleting, or if you suspect an app is creating large files without your knowledge, contact IT support. They can analyze in detail what is taking up space and suggest safe steps, with a prior backup of important data.

Does clearing cache affect my data?
No, clearing cache only removes temporary files. Your data, logins and saved content remain intact. You may only need to log in again to some apps if you clear data as well, not just cache.
How do I find the largest files on my phone?
Open the `Files` app and look for a storage analysis option or sort files by size. There you will see a list of the largest files and can delete or move them. Pay attention to videos and archives.
Can I expand my phone storage?
If the phone supports a microSD card, you can add one and move media to it. Most modern phones do not have this option, so the solution is to use cloud storage or move files to a computer.
