Android’s Calling Cards could be coming soon to Wear OS
Source: Android Authority
TL;DR
- Google is working to bring Calling Cards support to Wear OS, enabling personalized, full‑screen call backgrounds on smartwatches.
- Evidence found in the latest Google Phone beta suggests that Calling Card metadata and images will soon sync from Android phones to paired Wear OS devices.
- While the full‑screen image is expected to sync, the current code indicates that custom font styles and colors may not sync. The final implementation could differ.
Calling Cards on Android took inspiration from iOS’s Contact Posters, though there are some significant differences. Users currently cannot set their own Calling Cards, but Google is working to address this complaint. Another oversight is that Calling Cards are not supported on Wear OS, so users see the standard Wear OS call screen even if they have set up Calling Cards on their phone. Recent clues indicate Google is working to bring Calling Cards support to Wear OS.
Calling Cards can be used to personalize calling screens with a full‑screen image. When you receive a call from a contact whose Calling Card you’ve set up, you’re greeted with a visually immersive, customized screen rather than a generic incoming call screen.

Currently, Calling Cards work only on Android phones. On a Wear OS smartwatch you will see the standard Wear OS calling screen.
If a contact has a profile picture (different from a Calling Card), the standard Wear OS incoming call screen looks like this:

In the latest Phone by Google v210.0.870571680 beta, clues indicate Google is working to bring these full‑screen call backgrounds to Wear OS.
Code snippets
CALLING_CARD_METADATA_TO_WEAR_SENT
CALLING_CARD_SYNC_TO_WEAR
These strings point toward sending and syncing Calling Card data to the paired Wear OS smartwatch, potentially allowing users to see the same Calling Card images from their phone directly on their watch.
The code suggests that only the call background (the full‑screen image) would be synced to Wear OS, not the custom font style or color. This makes sense given the smaller screen size on smartwatches, which can affect legibility. More clues or an official rollout will be needed to confirm the final implementation.
⚠️ An APK teardown can predict future features based on work‑in‑progress code, but such predicted features may not reach a public release.
