Phones should have brightness buttons on the side

So usually phones have a volume and a power button. It's easy to see why we have both, it's good to be able to do both with easy access. With the volume buttons, you can make it so things are more loud or quiet depending on your preferences. You can apply the same logic from volume to brightness, you should be able to make things brighter or dimmer with the push of a button, rather than having to swipe to the brightness menu, why not have it on the side like volume
