Good to know! The physical kill switch would be nice, but considering the goal is to have a not hacked phone to begin with, mic and camera shouldn’t be a problem if the phone stays un-hacked.
I’d very much like to go as cheap as I can, I’m just daunted by tackling the diy version. I did read through the installation instructions, and I feel like I only understood about half of it.
Perhaps it makes more sense if you’re actively doing it with the phone in hand though.
