Some Androids (like mine) won't lock for a few seconds after turning off the screen. It's a nice feature when you press to turn off the screen, and quickly realize you need to do something else. Just turn on the screen and it's still unlocked.
Entering the pattern after it's locked is pretty much impossible though.
I can configure how long that delay should be. IIRC it's int he display/lockscreen menu.
I don't like it tho, as I much prefer the device to be locked when I tell it to, so I won't have to care anymore. The fingerprint scanner on the back makes the unlocking trivial though.
It might, but it hasn't in the 18 months I've been using it. I don't know what the timer is supposed to be, but it seems like something less than 2 seconds. I'm pretty sure I couldn't get my phone in my pocket and press the power button that quickly if I wanted to.
Also, the case adds to the pressure needed to depress the button anyway.
