Android 17 also brings updated privacy and system options. The changes are intended to make everyday tasks easier to manage without needing to search through several settings pages.
Visual Enhancements
The update refreshes parts of the interface, including system icons, Settings screens and the status bar. It also adds visual changes to the lock screen and wallpaper experience, while updated typography and smoother animations give the interface a more consistent look.
Other visual updates include expanded Dark Theme support and improved handling of HDR content. The exact appearance can depend on the feature and the screen currently in use.
Fresh Widgets
Nothing OS 5.0 adds new widget options, including Collector, Away Time and Glyph Timer. These give users more ways to view selected information or access a function directly from the home screen.
The update also improves home-screen customisation, including tools for arranging app icons and widgets. This can help users organise the home screen with fewer individual moves.
Camera Enhancements
The camera app receives interface and feature updates. The changelog covers improvements related to video recording, zoom, close-up shots, QR scanning, Lens and Motion Photos, along with a refreshed camera layout.
These changes focus on camera controls and supported shooting options. The update does not change the phone’s camera hardware.
General Improvements and Bug Fixes
The release includes system refinements such as improved animations, updated status indicators and changes to Bluetooth controls. Bluetooth devices can be managed more directly from Quick Settings, while Live Updates and lock-screen shortcuts also receive improvements.
The update also includes Noto 3D Emoji support in Gboard and changes to the way notifications and Quick Settings are presented. As with any software update, users should check the phone after installation to make sure their regular apps and connections work as expected.
