To make space you can:
Delete texts or emails. If you have a lot saved on the phone, this can help.
Delete or move photos, videos, documents, etc.
Uninstall app updates.
Uninstall apps.
Clear cache files. However, this will only make space temporarily as cache files will rebuild over time. Also, while clearing cache files won't hurt anything, they're there to speed up operation and should be left alone. An empty cache is worthless.
If you can't move stuff to a SD card, move them to your computer or cloud storage.
