Phone storage

My phone storage for norton is 98% full and I don't know how to send it to free up space.

And what Android version is on this device?  

And where are you seeing Norton Storage being 98%?  If in Android Settings, which section of the Settings pages?

 

Samsung…

What device and OS version are you using? 

I have not seen any device that allots a given amount of storage to an individual device. Where are you seeing this information?
