There are settings you can change which let you choose the amount of time before the phone locks, after the screen has gone off by itself.Thanks I'll give it a shot. Does anyone know what the time out for the FP sensor is to kick in? It seems I can turn my phone off and if it's a short period I only have to swipe, no FP sensor. I wonder if this time frame is adjustable.
Also I think someone earlier posted an app to keep the FP sensor on only when not on a friendly WiFi. That might be interesting.
An app which would allow you to disable the lock whilst connected to a friendly wifi point is Tasker, though I'm not 100% sure if it would work with fingerprint scanner.
