Is there a way I can force a prompt for passcode unlock without disabling touch ID?
I have some gloves with capacitative tips on the index fingers. I can use them relatively well to navigate the phone once the phone has UI elements up on the screen but I'm having a lot of trouble bringing up the passcode prompt. The gloves don't seem to trip the touch ID sensor to appear as an unknown fingerprint.

I use the following technique to present the passcode screen, without disabling the Touch ID:
Press the Home button slowly (once, or if needed, twice, i.e. not fast enough to trigger the Apple Pay screen) with a fingernail or the tip of any of your finger or thumb vertically, such that the Touch ID sensor doesn't register any fingerprint.
This should present the passcode screen without disabling the Touch ID.
