This update lets you experience the latest version of Nothing OS ahead of the official release and share your feedback to help us refine the final build. #### **What’s New** **📱All-new Nothing icon design** A refreshed visual language that’s lighter, more refined, and uniquely Nothing. Expect further improvements based on your feedback. ![](https://cdn.nothing.community/2025-10-24/1761296699-291664-image.png "banner") **📸 “Stretch” Camera preset** Developed in collaboration with photographer *Jordan Hemingway*, this preset enhances photos with deeper shadows and extended highlights for a distinctive, cinematic look straight from the Camera app. 🖼️ Lock Glimpse Lock Glimpse brings fresh, high-quality wallpapers to your lock screen, curated to your taste across nine categories. It can also surface timely updates and useful content designed to enhance your experience. The feature is turned off by default. You can enable it anytime in Settings, refresh wallpapers, adjust your preferences, or choose to access it only by swiping left. Everything stays in your control. Built with privacy in mind, Lock Glimpse will soon let you display your own photos on the lock screen, replacing all other content and making every unlock uniquely yours. ![](https://cdn.nothing.community/2025-10-24/1761295380-318183-frame-2147227094-2.png "banner") ⚡All other features remain the same as in the previously released [Nothing OS 4.0 Beta](https://nothing.community/d/43141-nothing-os-40-open-beta). #### Notes Please back up your data (photos, call logs, contacts, etc.) before upgrading.

Rob ⚡️ Just asking- do you have an approximate date for the stable to roll out to the Nothing Phone 3a?

I also like the new status bar; however, I have seen many people complaining about the spacing. Was it just a bug or something else?

Also , if possible, please add a more detailed AOD, as most of the phones have an amoled display which is perfect for displaying images. I’ve noticed that the aod can also show images in OnePlus’ phones.

Looking forward to the stable rollout.

Bro why are you waiting, it does not worth the wait no major changes are there and it might have more bugs as they have note done beta testing properly

Naren I love to click photographs in my phone 3a pro. I am eagerly waiting for the watermark styles and ofcourse it’s a stable, so we get better animation improvement and smoothness.
