WhatsApp is adding a night mode feature to its Android app, aimed at improving photography in low-light conditions. This feature has been identified in WhatsApp Beta for Android version 2.25.22.2 and includes a moon icon in the camera interface for manual activation. The night mode enhances image clarity and brightness by adjusting exposure and minimizing noise, allowing users to capture more details in dim environments. It is currently available to select beta testers and is expected to roll out to a wider audience in future updates.
