Yeah. Not sure if regular android has it but @GrapheneOS has a wifi and Bluetooth auto shut off. I set it for 1 min after disconnect to help minimize exposure. No auto full airplane mode though...maybe they'll add that in the future.

I have this feature on my android in developer mode - use ot constantly. S21

Dedicated cellular toggle is even better. Awesome.

Does airplane (on android) mode really cut off all signals? Even cellphone waves? I always wondered
