Apple now simplifies the installation of iOS betas using wireless updates. Although IOS Public Betas are easy to install, they can also be flawed. Fortunately, you can end the public beta for iOS at any time.
How the Public Beta Program Works for iOS and iPadOS
Apple's iOS / iPadOS public beta program works with a profile on your iPhone or iPad. Once the profile is installed, you can request the beta version of the operating system in the Software Update section.
You can stop the Public Beta program at any time. However, removing the public beta profile will not affect your iOS or iPadOS device. They continue to run the beta version. You can continue to do so and wait for the public version to be available for the upgrade. If you want, you can also downgrade to the former, stable version of iOS or iPadOS. The following describes all available options.
A word about backups
It's best to back up your device before making any major changes, such as: B. install a beta version or leave the beta program. This is especially important before you install the public beta.
Apple does not allow users to restore a backup from a version higher than the one you are running. For example, if you back up from iOS 1
You must set your device as new, or you must restore the backup from iCloud or a third-party app. If you leave the iOS / iPadOS public beta program and restore the stable beta version without an older backup, all your data will be lost.
Before you begin, make a backup with iTunes. Open the iTunes app on your computer and connect your iOS device. Then go to the device management screen by clicking the device icon in the top toolbar. Find the "Backups" section here and select "This Computer". Then click on "Backup Now".
iTunes is not supported There is a third-party app that allows you to back up data from a beta version and restore it to a previous stable version. You can use the dr.fone app to create a full backup and restore the entire backup, or just a few apps at a later time.
How to Leave the iOS or iPadOS Public Beta
The public beta for iOS or iPadOS is as simple as removing the public beta profile.
Open the Settings app and go to the "General" section. Scroll down and tap the "Profile" option.
Your iOS public beta profile will be displayed here. Touch it.
On the next screen, tap "Remove Profile". Apple prompts you to enter the device passcode.
Tap "Remove" in the next pop-up window to confirm.
Now the public beta profile has been removed from your device (the process will complete when you restart the device). You will no longer receive beta updates on your iOS or iPadOS device.
How to Downgrade to a Stable iOS or iPadOS Version
With iTunes, you can always downgrade to the latest stable iOS version.  Open the iTunes app on your Mac or PC and connect your iPhone or iPad. Click the Device icon in the top toolbar to go to the device management screen. Depending on the device, click the "Recover iPhone" or "Recover iPad" button. Make sure that Find my iPhone or Find my iPad is turned off before.
iTunes now checks your device and downloads the latest stable version of iOS or iPadOS. After downloading, the entire device is deleted and the operating system is installed.
Once your iOS device is restored, factory defaults will be restored. If you have a backup, click the Restore Backup button to start the restore process. Once you see the hi-screen on your iPhone or iPad, you can use your device.
