- Viewing the phone screen in sunlight is nearly impossible if auto brightness is not turned on.
- Sunlight mode is a feature that provides extra nits of brightness when using the phone outdoors for comfortable viewing.
- It adjusts the phone screen brightness to strong ambient/surrounding light when the automatic brightness is off.
- If for example, you get 500 nits as the default phone screen brightness, you can get 1000 nits using Sunlight mode.
