Thanks for the cue, I didn't know that. But I'm afraid that most "stock" users will never use that option. Heck, even knowing it I can't be sure if I want to spend time to research this (there is a word "jailbreak" behind your tip, right?) or just to admit that my switching experiment failed and to go buy yet another iphone instead.

This idea of faking may be the solution against bad actors, but not until apple and google would make that option official. And even then most of naive users will be tricked and burdened into not using it.
