Double tap Navigation bar on WM10 to lock the screen

[sunbee]

Most times the screen locks me out without I press the power button while using the phone and today I simply tried to replicate that on my L730 and found out how.
If you double tap on the blank space on either corner of the onscreen navigation bar the screen locks you out.

I don't know if it's a bug with WM10 build or a hardware problem with my phone or if it's a feature with new build.

This is an old feature in 8.1 update 2 which is also in 10
