Deep Dive on Cloud Phone User Agents

Why it matters? User agents are the most common way to identify devices on the web.

A similar deep dive was completed for KaiOS user agents.

Key Takeaways

Cloud Phone user agents follow a consistent pattern including several components:

User Agent Components

Cloud Phone identifies all Cloud Phone devices
Puffin identifies the remote-browser architecture shared with the Puffin browser
Nokia 225 4G is the device model name. Generic is used by the Cloud Phone Simulator or pre-production devices
Chrome/128.0.6613.170 identifies the Chromium version used by Cloud Phone servers

For compatibility, Chromium adds strings like KHTML, like Gecko and Safari.

User Agents

Here’s a list of User-Agent header values from recent requests to PodLP.

Limitations: these user agents are limited to a sample from a fixed time window, deduplicated on Cloud Phone version and build identifiers. PodLP is not available on all Cloud Phone models.

Using User Agents

The most important user agent segmentation is between Cloud Phone and non-Cloud Phone devices. All Cloud Phone models will include the identifier Cloud Phone.

1function isCloudPhone() {
2    const normalizedUserAgent = (navigator.userAgent || '').toLowerCase();
3    return (
4      normalizedUserAgent.includes('cloud phone')
5    );
6}

User agents can also be used for check Cloud Phone version (i.e. 2.7 vs 3.1), although feature detection and runtime checks for specific APIs are a more reliable way than version detection.

Finally, user agents could be used in contexts where feature detection isn’t available to identify information like the device model and manufacturer. From the list above, popular Cloud Phone manufacturers include: Nokia, HMD, GDL, Goly, ringme, Foneme, BlackZone, Snexian, Itel, Viettel, and Proton.

Conclusion

User agents are an easy way to adapt your widget to a variety of devices. While it’s preferred to use feature detection, knowing the gamut of available user agents helps determine the most reliable identifiers for segmentation or behavior change. If you need support adapting your Cloud Phone widget, contact the author from the About page.
