Anybody find a good LED Flashlight app? TeslaLED works good but takes a good 5 or so seconds to come on. Also my Nexus's face unlock isn't nowhere near as fast as the ones u see on youtube and such. I press the power button and the camera box is black for a second or 2 then my face shows up for a second or 2 then it unlocks. Every other video I have seen has it to where the phone is unlocking right when the screen is coming on from pressing the power button.
