The new Nothing OS 4.0 update also brings the Extra Dark Mode feature to Nothing Phone models, which is said to help in improving contrast, displaying deeper blacks, reducing power consumption, and a more comfortable viewing experience in low light conditions. Essential Space and Launcher will also support Extra Dark Mode. The Android 16-based firmware also features new interaction and app open and close animations, haptic feedback at volume limits, and enhanced notification interactions. Additionally, users will also be able to resize Weather, Pedometer, and Screen Time widgets to 1x1 and 2x1 layouts.

On top of this, Nothing OS 4.0 lets users hide any app of their choice from the app drawer. It also brings the pop up view feature, letting people open two apps in floating windows. They can switch between the two using swipe gestures, too. Lastly, Nothing Phone 3 owners will get the new Flip to Glyph controls, improved Pocket Mode, and new Glyph Toys. Moreover, the Glyph Mirror Selfie feature now lets users save the original photo as “an extra photo” in the native Gallery app.
