lock with a pattern of power/volume keys

[Sherif Hesham]

please, is there an app that locks your phone with a special pattern of presses on the power and/or the volume keys so when locked the phone looks like is is switched off until you press the right pattern on the power and/or volume keys ??

Welcome to the forums!

Something like you are asking would be embedded in the ROM itself. I may be wrong, but that seems like a ROM function to me.
