Your screen turns on with every movement in your cell phone holder? Use my Activator 'Activate' action to temporarily disable the raise to wake feature. For example, activate it when you're connected to your cars bluetooth. Use the 'Deactivate' activator action to reset the raise to wake settings to default. (For example, if you are no longer connected to your cars bluetooth.)
This Tweak adds a 'Activate' and 'Deactivate' action to activator.
Compatible with iOS 13.5 (Not tested on any other version)
Activator from @rpetrich needs to be installed.
