- Launch the device settings
- Scroll to Display
- Select brightness, uncheck automatic brightness
- Drag bar left to right to make brighter / dimmer
While the device defaults to Auto, this is not always the best setting as often times users can use the device at a lower brightness, which consumes less battery. In the direct sun light you may want to change it back to full brightness, but play around with it, and set it up to your personal preferences.
