    Does this happen for everyone? It attempts to scan but fails and I have to enter my passcode.

    It's not a big issue but I just wondered if this is the norm.

    Charge your phone. ;)

    I dunno, my phone never gets that low, so I have no interesting input for you.

    My guess is that the IR mesh takes a bit of power, so once you're below a certain threshold, it just defaults to passcode only.

    Yes, someone else posted that it stops working at 10%. Makes sense, considering how much processing power it uses.
