There are free and open source apps for Android that automatically lock the device when the accelerometer detects rapid acceleration, which is a simple detection method. For example, Private Lock is on F-Droid:

- Private Lock (source): https://github.com/wesaphzt/privatelock

- Private Lock (F-Droid): https://f-droid.org/en/packages/com.wesaphzt.privatelock/

Very interesting.

Gotta admit first thing I would do is stage a theft scenario to see how it works.
