In Android, it&#x27;s super simple for an ads framework or a malicious framework - installed as part of some useful app - to run a background service and keep recording microphone and phone calls.<p>It is possible to hack the Android platform or OS to prevent or mitigate mischief like that, but ironically, it requires devices to be rooted.<p>Android architecture rewards the bad guys by obstructing the good guys!<p>I think mass migration of all devices to something like Cyanogenmod is the only solution.
