A screen that is too bright can tire your eyes. A screen that is too dim is hard to read. You can change it any time. You will not break anything by trying. It changes right back if you do not like it.

Hello, it is Buddy. Today we make your screen brighter or dimmer. This is a kind thing to do for your eyes. Let us do it together, slow and easy.

Let us go through this together, one little step at a time.
Tap each step once you have done it. This is just for you. Nothing is timed, and nothing can go wrong.

A dim screen at night is gentle on tired eyes. A bright screen helps in sunshine. Change it as often as you like.
The little sun means brightness. More sun means brighter. Less sun means dimmer. You can always change it back.
