Purim’s upcoming Librem 5 smartphone has two key selling points. First, it will ship with free and open source GNU/Linux software featuring as little proprietary code as possible. And second, it features kill switches that can disconnect hardware. Here’s the idea: flip all three kill switches and the Librem 5 will shut down all of the sensors that could be used to track you. Off goes the mic, the camera, the WiFi, Bluetooth, and Cellular wireless radios. But it’ll also shut down the GPS, proximity sensor, ambient light sensor, accelerometer, compass, and everything else.
