How you do raise or lower the brightness on the iPod Touch 4th generation? This tutorial describes how to adjust the screen brightness on your iPod.
- Open the Settings app.
- Scroll down to Brightness & Wallpaper and tap it.
- Move the slider at the top of the screen to the left to reduce brightness, and move it to the right to raise the brightness.
- Below is an option for Auto-Brightness. It will automatically adjust the brightness depending on the light conditions. From experience, I recommend not using this feature as it is more annoying than helpful.
