This is tangential, or only a part, of the current tracking concern. But the accelerometer in my 2013 Nexus 7 died, perhaps after a relatively minor blow it took when I was taking it out of its storage space and mis-judged clearance. (Accelerometer death is a known issue for this model.)<p>That doesn't fix the GPS, WiFi, Bluetooth logging, nor the screen activity tracking, but it does "fix" the tracking of how I hold it, move it around my person, and so on.<p>Maybe we will be taking to deliberately, physically crippling our devices, to keep their overlords from "observing" our every moment and action. We already tape over our cameras...<p>In a more sane -- for me -- world, I'd have controls to turn this crap off. Not / no longer being very trusting, I'd have physical controls.<p>Instead, science fiction is again becoming reality, where we will seek out device and tech "gurus" to kill the malicious functionality in our "own" devices.
