So far, Pixel devices have supported only basic customization. Users could change wallpapers, adjust accent colors, or pick from Material You presets, but everything had to be set up individually. That might change soon. The new beta includes hidden code for a feature called Pixel themes, which could bundle multiple visual changes together for quicker and more flexible personalization.
Within the beta, a new Themes button has been found in the Wallpaper & Style app, along with a description that reads, “Discover Pixel themes.” Although the button and a related chip under the wallpaper preview can be forced to appear through debugging tools, neither is currently functional.

Combined with the more Expressive Material 3 changes already present in Android 16 QPR1, these early signs of theme pack support hint at a new direction for the Pixel software experience. While we don’t know when or if this feature will officially roll out, it’s clear that Google is at least experimenting with the idea — and that could be a welcome change for users looking for more control over how their Pixel phones look and feel.
