📝 Key Points of This Article

• A quiet update for the Google Pixel “Theme Packs” app, version v1.0.813105288.stub, was released in mid-January 2026.
• It has been revealed that the app now supports “Split APK,” a specification that divides the app configuration to allow for partial update installations.
• This suggests that themes containing new wallpapers, icons, system sounds, and GIF animations may be delivered via future app updates.

In November 2025, Google began rolling out the new “Theme Packs” feature inspired by the movie “Wicked” as part of the November 2025 “Pixel Drop” for Google Pixel devices running the next-generation Android 16 OS.

The “Theme Packs” feature from the November 2025 Pixel Drop is a customization tool that allows users to tailor their Google Pixel device’s wallpaper, icons, system sounds, and GIF animations to a specific theme. Specifically, the “Theme Packs” app is distributed through the Google Play Store.

While the “Theme Packs” app currently features themes inspired by the movie “Wicked,” this has been limited to overseas markets. Despite an initial announcement that it would be coming soon to Japan, the release has yet to happen, even as we approach the January 31, 2026 (Saturday) deadline for the “Wicked” theme distribution.

Regarding this Google Pixel “Theme Packs” app, update version v1.0.813105288.stub was quietly released in mid-January 2026. Analysis of the internal code for the v1.0.813105288.stub update revealed that the app now supports “Split APK”—an app specification that divides the app configuration to allow for partial update installations.

<manifest ...
    android:requiredSplitTypes=""
    android:splitTypes=""
    ...>
    ...
    <application ...>
        ...
        <meta-data
            android:name="com.android.vending.splits"
            android:resource="@xml/splits0"/>

        <meta-data
            android:name="com.android.vending.derived.apk.id"
            android:value="1"/>
    </application>
</manifest>

The “Theme Packs” app’s support for “Split APK” likely anticipates the rotation of themes when new ones are released in the future. While the “Wicked” movie-inspired theme is currently being featured, it is possible that once its distribution period ends after January 31, 2026 (Saturday), new themes containing fresh wallpapers, icons, system sounds, and GIF animations will be delivered via app updates.

In contrast, the early versions of the “Theme Packs” app did not support “Split APK,” meaning the wallpapers, icons, system sounds, and GIF animations were bundled directly within the core of the app. Consequently, while the “Wicked” theme will likely not see a release in Japan, we can expect other themes to be rolled out through the “Theme Packs” app in the future.
