Nothing Phone (3a) Series Users Rejoice! Good news for technology lovers! Nothing has finally released its latest Nothing OS 4.0 Open Beta update for the Nothing Phone (3a) and Phone (3a) Pro models as well.
The company rolled out this beta update some time ago for Phone (3), Phone (2), Phone (2a), and Phone (2a) Plus users.
Now, as promised, Nothing has made this new experience available to users of the (3a) series as well.
New Design and Improved Visual Experience
The all-new Nothing Icon Design is the largest modification in Nothing OS 4.0.
The company has also lightened its visual language, streamlined, and modernized it. The new icons are cleaner than ever and complement the brand more on the Uniquely Nothing identity.
Nothing says that further improvements will be made to this design based on user feedback.
Lock Glimpse: Now Your World on the Lock Screen
Another interesting feature of this update is Lock Glimpse.
It offers a new lock screen experience, providing you with high-quality wallpapers in nine categories to suit your taste.
In addition, this feature will also periodically show you important updates and content.
The company will soon be adding a new option that allows you to set your own photo on the lock screen—making every unlocking experience a personalized experience.
Improvements to Other Features
Nothing OS 4.0 also improves camera presets, notification handling, and system performance.
While most features remain the same as previous OS 4.0 releases, Nothing has further stabilized performance to provide a smoother user experience.
