Google Pixel 2 XL On AT&T Receiving Android 8.1 OTA, Adds HD Voice Calling

AT&T is distributing a new update to the Google Pixel 2 & Pixel 2 XL. The Android 8.1 Oreo introduces a variety of improvements, as well as a number of user-facing additions and optimization.

This update, which is rolling out now, adds HD Voice Calling support for customers on the network. HD Voice uses wide-band audio technology and noise cancellation to improve call quality. The release notes for the update prominently cite the inclusion of “HD Voice Calling for AT&T users.”

In order to enable the feature, head over to Settings > Network & Internet > Mobile Networks and tap on the “Advanced Calling” toggle. Keep in mind that you also have to be located in an area that supports the service.

This update also adds a light navigation bar to system apps like Settings to combat the Pixel 2 XL’s burn-in/screen retention issues. Touch responsiveness issues and audio recording bugs during video capture have also been addressed.

The included December security patch also includes a fix for the KRACK Wi-Fi vulnerability. Under-the-hood, Android 8.1 enables the Pixel Visual Core for third-party apps, while there is support for the new Neural networks API for hardware accelerating on-device machine learning. The update has a file size of 531MB.

The software package is currently rolling out automatically, although it may take several days before all devices receive the update. However, customers may also proceed to the device settings and attempt to manually trigger the installation process.
