Flashlight on lockscreen on Galaxy S5 I am soon going on a field trip and would like to give my friends the ability to use the flash light from the phone without giving them the pattern to unlock the phone. Is that possible to add the flashlight/torch to the locked screen just like the camera?

I have a Galaxy S5 with Android 4.4.2
Not without a different ROM but you may be able to add one to the notification area. Try this, I don't know how well (if at all) it works on the S5 but it's worth a shot.
