AI Dashboard, Better Privacy, and New Widgets
In NothingOS 4.0, you will see a new AI Usage Dashboard that shows how often AI features are running in the background. This gives you more control and a clear idea of what’s happening on your phone. Along with this, now you can hide apps directly from the home screen, which is helpful for privacy. Widgets also get new sizes in NothingOS 4.0, so adjusting weather, steps, screen time, and other widgets becomes very easy. Everything feels more organised and simple to use.

Camera Changes and Multitasking Boost
The camera app also gets a neat redesign with new filters and Motion Photos support, so clicking pictures becomes a little more fun. Multitasking also improves because NothingOS 4.0 brings Pop-Up View, which helps you open apps in floating windows while doing something else. It’s helpful when you are chatting and quickly checking information. The Glyph Interface also gets fresh patterns, so notifications feel more active and stylish. Overall, the update brings small but useful changes.
