While the headline concentrates on the camera, it's the microphone we should really worry about. Cameras are easy to conceal. But there's no way to reliably disable microphones. And the most personal and possibly incriminating information is in someone's speech.

The accelerometer/gyroscope information is possibly even worse. It has been shown that speech can be reconstructed from their signal. What makes this bad is that even apps which are not authorized to access microphones are liberally given access to them. Even worse, they give additional information of a person's habits like sleep cycles, physical activity, health and driving.
