Nothing OS 4.0 with Lock Glimpse

Nothing OS 4.0 is here — and it’s actually revolutionary.

After testing the beta version for a few days, I can confidently say this update is more than a visual refresh. Nothing has delivered a performance boost, deep AI integration, and a reimagined user experience that feels futuristic yet practical.

The new Lock Glimpse feature is a standout. It offers curated wallpapers from nine categories, with optional links for quick exploration. It feels personal, dynamic, and privacy-focused — a refreshing balance between customization and control.

Then there’s the AI Dashboard — one of the most transparent AI tools I’ve seen on a smartphone. You can see exactly which models (Whisper, GPT-4o, Gemini Flash) are active and their real-time battery impact. For developers and AI enthusiasts, this feature is pure gold.

Performance is up by 20%, multitasking is smoother thanks to Pop-Up View, and Extra Dark Mode finally gives OLED users a true black experience.
