To turn on an Android phone without Power button, put the phone in fastbooot mode using Volume Up+Volume Down and connect the phone to a computer.

Now, if you, like countless others have been using an Android phone for quite some time, you know that long-pressing the power button on your smartphone pops up the shutdown or restart options.

Press and hold the volume down and power button for a few seconds. Pull down the notification shade and tap the power button icon. Tell Bixby to turn off your phone.

The power button is a basic accessibility feature, but we need consistency in the Android world to define what it can and cannot do.
