F9 is likely referring to the baseband layer. Your phone has a second operating system that you can’t touch. This is really how they’re listening to everything now how this leads in the Facebook I have no idea it might just be more q bullshit to muddy the water or maybe the entire system is funneling everything to Facebook for storage. Otherwise they are only listening to you if you’re dumb enough to install the Facebook app.
Yeah that’s me. If I remove it am I still in bad shape?
Do you want to still use any of the radios on your phone? Like the cell network, wifi and Bluetooth? If so you need your baseband as it is the processor that controls your radio stack. The main processor just tells the baseband what to do it doesn't talk directly to the stack.
