Apple says, "This beta version of iOS should only be deployed on devices dedicated for iOS 15.2 beta software development."
What's New: App Privacy Report ● iOS 15 and iPadOS 15 introduced the Record App Activity feature in the privacy settings, allowing people to save a summary of sensor, data, and internet access by apps on their device. In iOS 15.2 beta and iPadOS 15.2 Beta, this activity is presented in Settings in a new UI called App Privacy Report. This is a great opportunity to review your app’s sensor, data, and internet usage. To view your activity in the report, go to Settings > Privacy > App Privacy Report > Turn On App Privacy Report. Activity will show once you use your app. (78696668)
Location Emergency ● Auto Call can now be set up to use one of two methods for initiating an emergency call: holding the side button together with a volume button, or rapidly pressing the side button multiple times. Both methods now show a longer, 8-second countdown before placing an emergency call. (84620050)
