You Should Prepare for iOS 13.2.3
If you're planning to move your iPhone 11/iPhone 11 Pro/iPhone 11 Pro Max to iOS 13.2.3, make sure you prepare yourself, and your device, for the move.
There's no way to predict how iOS 13.2.3 will run on your phone so you'll want to do some prep work ahead of time.
If you don't know how to prepare, please take a look at our pre-installation guide. It will take you through the process we typically use before we install new iOS software on our iPhones.
If you don't have a ton of free time to devote to the pre-installation process, be sure to backup the files on your phone.
Data loss issues are rare, but you'll want to play it safe.
