This is no an issue with “other manufacturers bluetooth” Its an Apple issue that Apple refuses to address.. Everyone these days has multiple Bluetooth devices in their Bluetooth menu. Anytime YOUR phone sees another device either turn on, or just come in its range, it switches devices..You. Constantly are adding new features. Some cool, and some useless. When your customers are pointing out an annoying issue to them, why do you choose to pass the buck instead of addressing it?
add a switch you can swipe on that disables this “switch to whatever new device is nearby “mode.
instead of, you tell your customers to delete all the other devices you dont want it to switch to ( Not an option)
