How to update my new version

Hi dadabaranking,

Welcome to the Apple Support Community. To update your iPhone to the newest iOS (13.6.1) you can update in the Software Update tab in Settings<General<Software Update. It will tell you if you need any update or if your phone is up to date. If you want to update to iOS 14, you can install the profile from the Public Beta Site. I will link the site under this. Good Luck
