30 GB System And Phone Storage.

My iPhone 6s+ Has 32 GB, I Delete Something For Storage And Still Don't Have Storage! My Phone System Is Over 30 GB So It Means I Only Have 2GB. I Only Have Apple Default Apps. I’m Stuck On IOS 13.5 And Can’t Install Any Updates. I Have No Games No Nothing And My Phone Still Has 31.9 GB. Can’t Wait For My Phone Upgrade. It Will Be The 12 Pro Max And I Will Not Have Any Of These Issues.
