I think having the power circuit cut off is definitely better than anything on os level when malware is on the device, LTE killswitch is hard to find
another solution is a removable 🔋 battery
how many phones out there can run graphenos and have a removable battery?
I would rather swap those and not use pixels
if I can't remove the battery it has to sit in a Faraday bag...having a physical switch for LTE is amazing feature that barely any other device has got (librem5)
there are devices that allow for camera and microphone killswitches but no WiFi/BT/LTE
