Can I change the screen brightness?
From Nintendo Support:
- Select the HOME Menu Settings icon in the upper left corner of the HOME Menu.
- Nintendo 3DS, Nintendo 3DS XL, and New Nintendo 3DS systems: This icon looks like a wrench, a sun, or a home with a wrench superimposted over it depending on the system menu version.
- Below "Screen Brightness", tap on the desired brightness level.
- If using a New Nintendo 3DS XL, be sure to turn "Auto-Brightness" to "OFF" or the system will automatically reduce the brightness levels based on environmental conditions.
- Tap "OK."
