MIUI’s Hidden Brightness Feature — Enhancing Visibility Under Sunlight

As mobile devices have become an indispensable part of our daily lives, we often find ourselves using them in various lighting conditions, including direct sunlight. However, using smartphones under bright sunlight can be challenging due to reduced visibility caused by glare and reflections. To address this issue, Xiaomi’s MIUI has introduced a hidden screen feature that optimizes the display settings to enhance visibility under bright sunlight. In this article, we will explore this lesser-known feature and its impact on users’ mobile experience.

The Hidden Brightness Feature

The hidden screen feature in MIUI aims to improve screen visibility under direct sunlight. It leverages the device’s ambient light sensor to detect increased sunlight exposure. When the sensor detects strong sunlight, the feature is activated, making real-time adjustments to the display settings, such as brightness and contrast.

How to Use the Brightness Screen Feature

Using the hidden screen feature is a straightforward process for MIUI users:

  • Step into sunlight, head outdoors where your device can be exposed to direct sunlight.
  • Ensure that the automatic brightness setting is enabled on your device. This setting allows the phone to adjust brightness levels automatically based on ambient light conditions.
  • As you step into sunlight, you’ll notice a difference in your phone’s display. The screen brightness will increase by a few hundred nits, and the contrast ratio will be adjusted accordingly.

Benefits of the Hidden Brightness Feature

Enhanced visibility

The primary advantage of the hidden screen feature is its ability to enhance visibility in bright outdoor conditions. By increasing brightness and optimizing contrast, users can now view their screens more clearly even under direct sunlight.

Improved readability

The feature ensures that text and images on the screen remain legible, reducing eye strain when using the phone outdoors for prolonged periods.

Better media consumption

Watching videos, viewing photos, or playing games becomes more enjoyable as the display adjustments enable a more immersive experience, with colors appearing more vibrant and details more pronounced.

Safer navigation

When using GPS navigation apps during outdoor activities, the hidden screen feature ensures that maps and directions are easily readable, preventing potential distractions and increasing safety.


The feature is designed to work only when necessary, activating itself when strong sunlight is detected. This helps conserve battery life by not continuously running at higher brightness levels.


The hidden screen feature in MIUI is a welcome addition for users who frequently use their smartphones in outdoor environments. By automatically adjusting the display settings, the feature significantly improves visibility, readability, and overall user experience under direct sunlight. Whether you’re reading an e-book, browsing the web, or using navigation apps, this feature ensures that your screen remains clear and easily readable.

As technology continues to advance, it’s impressive to see smartphone manufacturers like Xiaomi taking user needs into account and introducing innovative features that enhance everyday experiences. So, the next time you step out into the sunlight, let MIUI’s hidden screen feature take care of optimizing your display for better visibility, ensuring you stay connected and informed without any inconvenience.
