Galaxy S25 Gains Instant Hotspot Support Through Google’s Cross-Device Services

Google is quietly expanding its cross-device services, and now the Galaxy S25 instant hotspot feature is officially live.

The update was spotted on Google’s support page, which now lists the Galaxy S25 as compatible with Instant Hotspot. This feature allows your phone to automatically share its internet connection with nearby devices—like a tablet or Chromebook—when they need it.

Previously, Samsung phones were excluded from this Google-native feature. Samsung had its own auto-hotspot function, which wasn’t compatible with Google’s system. But that seems to be changing. Now, Samsung users can rely on Google’s cross-device services for seamless hotspot connections.

Interestingly, the support page only lists the Galaxy S25 by name. Tablets like the Galaxy Tab aren’t included yet. However, some users report seeing Instant Hotspot working on older Galaxy phones running One UI 7. That suggests the update might be tied more to One UI 7 than specific hardware.

Call casting and instant hotspot both rely on close-range device communication. They trigger automatically when one device senses the need—like a laptop without a connection reaching out for data.

This is a solid quality-of-life improvement, especially for people in the Google or Samsung ecosystem. No more fiddling with hotspot toggles—your device just connects.

While the official documentation only confirms the Galaxy S25 instant hotspot, it’s likely that more One UI 7 phones will gain access soon. As Google and Samsung continue aligning their ecosystems, features like this could become the new norm across Android.
