Disable Bluetooth. Use a cabled connection if you need headphones/mic.

If you need Bluetooth then check whether your phone has the same Broadcom driver - you might be fine depending on hardware. Or check if you can install open source firmware that includes a fixed driver.

There are other things you can do depending on device.

apple makes it kind of hard; three taps vs. android one swipe and one tap or are you implying it cannot be disabled b/c it is needed?

I am not sure how that is relevant, since this is about a current Android vulnerability.

But it's less of a problem in iOS anyway, because Apple provides updates for iPhones much longer. They are still releasing security updates for the iPhone 5s and 6, which are from 2013 and 2014 respectively.

I heard it’s equally hard on Android
