  1. Security experts have blown the whistle on countless software vulnerabilities, but it's not every day that hardware is blamed for compromising privacy. When such topics do arise, they usually focus…

    Why on earth you need an accelerometer in your phone?

    The accelerometer in your phone determines the screen orientation and works with image stabilization and is used as a tilt sensor for games.

    By this standard it can probably tell when you're beating off in front of your computer too.
  6. "Nonetheless, you probably shouldn't feel particularly alarmed about the discovery. It would still require an attacker to have some form of malware on the device (perhaps downloaded through an application store) and the researchers say the exploit is easily mitigated: just leave your phone in your pocket." - I always love these little summaries that would be so useful at the beginning of the article

    " Mobile operating systems let you restrict an app's access to sensors, but the accelerometer is often excluded. "

    Well theres the fix, just restrict app access...duh? In fact, and I know nothing about smartphones, I say in accordance with general privacy the user should be able to control access to ALL sensors...maybe the technology just isn't there yet? Or phones will never be as customizable as how your computer is?

    Option C, just don't worry about it and come to realize that if someone wants to tap your phone they can anyway. It would be way easier for someone just to borrow your phone for a minute and slip a tiny microphone into it to record everything then to try and decipher keystrokes.
