 ## Enabling Face Virtual HAL
 
-On pixel devicse (non-CF), by default (after manufacture reset), Face VHAL is not enabled. Therefore real Face HAL is used.
-Face VHAL enabling is gated by the following two AND conditions:
-1. The Face VHAL feature flag (as part of Trunk-development strategy) must be tured until the flags life-cycle ends.
-2. The Face VHAL must be enabled via sysprop
-See adb commands below
