Back in January, Google announced Android 7.1.2 beta for a handful of Pixel and Nexus devices including Pixel, Pixel XL, Nexus 5X, Nexus 6P, Nexus Player, and Pixel C.
Google said that Android 7.1.2 will be an incremental maintenance release focused on refinements, which includes bugfixes, optimizations, and a small number of enhancements for carriers and users. Along with these enhancements, the beta also brought new gestures 'Swipe fingerprint scanner to open notification' feature to the Nexus 5X.
Now, Rogers, the largest carrier in Canada has updated its Software update schedule and is planning to roll out a major update which will include VoLTE support and latest security patch for the Google Pixel on April 3.
This new update is likely to come with the latest Android 7.1.2 OS, as Rogers is said to be testing VoLTE service on its Pixels with the Android 7.1.2 beta.
Google has not said anything yet so naturally you should take it with a grain of salt.
