Google is updating its augmented reality SDK so that phones with dual cameras can capture better depth information. The most recent update to the Google Play services for AR app now notes’dual camera stereo depth on supported devices’.
The list of compatible arcore devices on Google’s developer site says that dual camera support will roll out in the coming weeks. Google’s own pixel 4 and pixel 4 XL were both released in 2019.
The pixel 5 and 4A 5G, both of which are 2020 pixel phones with dual cameras, wo n’t see the benefits for now. That may be because their secondary cameras are ultrawides rather than the pixel 4 and 4 XL’s telephotos.
