Camera app to bypass lock screen

[steveman1123]

I wasn't exactly sure which forum to post under, but do you knlw if there's a way of bypassing the lock screen with a camera? I want something like Rocket Player or certain flashlight apps that show up first, thrn if I press the home button the lock screen shows up. I would like to know if there is a decent camera app for that.
I have an LG Optimus F7 with 4.1.2
