If your phone keeps showing that the storage is full, there are a few things you can try to fix the issue:
Delete old or unused apps: Go through your phone and delete any apps that you no longer use or need. This will free up some storage space.
Clear cache and data:
Clearing the cache and data of apps that you use frequently can help free up some space on your phone. You can do this by going to Settings > Storage > Cached data and selecting "Clear cached data."Move apps and media to an SD card: If your phone has an SD card slot, you can move some apps and media to the card to free up space on the phone's internal storage.
Delete unnecessary media files:
Go through your photos, videos, and music files and delete any that you no longer need or want. You can also back up your media files to a cloud service or external hard drive to save space on your phone.Use a storage management app: There are several storage management apps available that can help you clean up your phone's storage and optimize its performance.
If none of these solutions work, you may need to consider upgrading to a phone with more storage capacity.
