Samsung Galaxy S24 storage is full or the device cannot install updates

The checks in more detail

Under Storage, Samsung's tool also lists large files, duplicates and unused apps that you can clear in one pass. Start with the Gallery. Samsung's Gallery can sync to OneDrive and Google Photos can back up to the cloud, and both have a Free up space option that removes the local copy of items that are safely backed up, which can release many gigabytes. Check that the backup finished before you delete anything locally. Delete the Trash and Recently deleted folders, which keep photos for thirty days, and empty them.

In the camera settings, change the video resolution or the format for everyday use, since high-efficiency formats take less space, and turn off settings that save an extra copy of each picture. Next, look at apps. In Storage, Apps, sort by size and consider the ones you rarely use; Samsung's Auto optimize and the Play Store's archive feature can remove an app but keep its data. Clear the cache of big apps such as social media and streaming from App info, Storage, Clear cache, which is safe, and clear downloaded videos in streaming apps.

Check the Downloads folder in My Files for old installers and zip files. Move documents to a computer or cloud storage. After you have cleared space, restart the phone, because the system takes time to recalculate the number. Keep at least ten percent of the storage free, since a nearly full phone becomes slow and fails to install updates. If you are always short, a larger model or a cloud plan is the lasting answer.
