It seems like I have less icons after I installed OS 2. For example I can no longer find the Power Off icon? I have to hold in the power button instead. I have swiped the screen but it's not there.
It was buggy and removed and the Battery Icon actually serves the purpose. Press the Battery Icon and choose PowerOff or Restart or the other functions.
As always, you can also hold your physical Power button down for one second, and it will show the same Restart/Stand By/Lock/Turn Off options that the battery icon would display.
