Most phones have a gyroscope and accelerometer in, I’ve been doing research and technically it would be possible to cause the system to enter full lock down or shutdown if the device is picked up and the password not entered within a timeframe for example if the phone is locked and picked up and nobody unlocks it within a defined time it would shutdown which means if the phone was snatched by a thief or bad actor the device would shutdown or force lock down which would protect a users data.
Just a thought I don’t know how practical it would be to implement however I am working on a similar project for pc so if the device is picked up it locks the device by detecting movement using a micro controller, since android devices have those sensors built in they could potentially be used to implant the same kind of security feature.
I am thinking that when the pirate Robert’s had his laptop snatched by the feds such a set up would have locked his laptop making data recover harder.
