In order to see the developer option in settings app you have to do the weird 7 tap on the version entry in the settings app (or something like this).
Isn't there as well a hidden way to enable a reboot option in the menu that appears when you long-press the power button ?
I know there are apps that do that for you, but why the hack wouldn't the stock Android that comes from Google for Nexus phones don't include a freaking restart option, only the Power off option ? I saw some phones with custom Android that have that option.
I know that pressing veeeeeeeeeeery long on the power button actually restarts the phone, but that looks to me like a final resort, in case your phone is stuck, or something, not a clean way to restart your phone.
