Following the recent announcement and initial Open Beta release of Nothing OS 4.0, built upon the Android 16 platform, for the Nothing Phone (3), Phone (2), Phone (2a), and Phone (2a) Plus, the company has now extended Open Beta availability to the Nothing Phone (3a) and Phone (3a) Pro models.

The Nothing OS 4.0 Open Beta implementation introduces a redesigned icon system to the Phone (3a) and Phone (3a) Pro. Furthermore, it incorporates a new “Stretch” Camera preset developed in collaboration with photographer Jordan Hemingway.

The “Stretch” preset, as described by Nothing, is designed to optimize photographic output through the enhancement of shadows and highlights, resulting in a distinct, cinematic aesthetic accessible directly within the Camera application.
Additionally, the Nothing OS 4.0 Open Beta integrates Lock Glimpse, a feature designed to present high-resolution wallpapers on the device’s lock screen. These wallpapers are categorized into nine distinct groups. Lock Glimpse is also capable of displaying timely updates and relevant content, intended to enhance the overall user experience.
