First of all, love this place! Been figuring out so many things Ok, the physical key that is the end/power button...a quick press shuts the screen off and it is seemingly off...is this standby then or does the phone have to standby itself? I ask because of this exceprt from the manual END/ POWERTo end a call, press to hang up. In standby mode, press to turn off the screen and lock the phone. In standby mode, press and hold to open the phone options menu that lets you turn on/off Mobile network connection, turn off the phone, or switch your phone to silent mode, vibration mode, or airplane mode.
