For grown-ups
Companion summary
Have you ever squinted at a tablet because the screen was too bright or too dark? You can change screen brightness on phones, tablets, and laptops every single day. A very dim screen saves battery power, while a very bright screen helps you see in sunshine. When you finish, try asking a grown-up to help you find the brightness buttons on a real device!
