Updated in UK
Pretty responsive though I've not tried any other device who uses face unlock
Update : pretty response isn't so much out of 10 tries about 5 worked weirdly only works when I blink figure that out and awkwardly held out in front of myself
updated here also in Brazil. Rom Europe STF-L09, Working well.
just a tip for those who did not know yet, activate the 'LIFT' option to unlock without having to click the power button.
