Can I update an iPhone 11 Pro to iOS newest software I’m having an issue

Hello Jakester763,

Thank you for reaching out to Apple Support Communities.

They Phone 11 Pro is compatible with the latest iOS 16 version. These steps will guide you on updating:

"Update your iPhone or iPad wirelessly

1. Back up your device using iCloud or your computer.
2. Plug your device into power and connect to the internet with Wi-Fi.
3. Go to Settings > General, then tap Software Update.
4. If you see more than one software update option available, choose the one that you want to install.
5. Tap Install Now. If you see Download and Install instead, tap it to download the update, enter your passcode, then tap Install Now. If you don't know your passcode, learn what to do."

More details can be found here: Update your iPhone or iPad

If you run into any issues can you provide additional details? What happens when you attempt to update? What is your current iOS version? Also, how much available storage do you have on your device?

Cheers!
