Hey there shawanda81,
We understand that your iPhone has low storage after an update. We'd like to help.
Which version of iOS are you on? We ask because the latest release is iOS 13.6.1, and this version has a fix for some storage issues.
If you haven't already, let's back up and update to that version. Use the steps here: Update your iPhone, iPad, or iPod touch
If you're unable to update due to storage, let's reference these steps: Clear Other storage on your iPhone or iPad
And if still happens, reach out to us here: Get Support
We hope this helps! Cheers.
