iphone 12 cases with auto wake/sleep function

Hello kenh0y,

Thank you for reaching out to Apple Support Communities.

We are not sure what case function you are referring to but these steps can help you set up raise to wake:

"Use Raise to Wake

When you raise your iPhone to look at it, it automatically wakes the Lock Screen. From there, you can quickly check your notifications, access Control Center, swipe left to take a photo, or swipe right to access widgets.

With iPhone X or later, you can also tap your screen to check notifications, take a photo, or quickly access the flashlight.

If you need to unlock your iPhone X or later, swipe up from the bottom of your screen. On iPhone 8 or earlier, press the Home button. If you don’t do anything, your iPhone will go back to sleep.

To turn Raise to Wake on or off, go to Settings > Display & Brightness.

On iPhone 14 Pro and iPhone 14 Pro Max, the Always-On display is on by default. Your iPhone dims the Lock Screen while still showing helpful information, like the time, widgets, and wallpaper.

To interact with your iPhone while the Always-On display is enabled, raise it, tap the screen, or press the side button. If you use Raise to Wake, raising and looking at your iPhone wakes your device as usual. You can also swipe up from the bottom of your display to wake iPhone and activate Face ID authentication."

Can you also provide a few more details and examples of what you are referring to?

Cheers!
