One of the many problems associated with Pixel 2 / Pixel 2 XL, is the sound quality of some users. It became known that the complaints ceased to be relevant after the transition to Android 8.1 Developer Preview 2. Corresponding messages appeared on profile forums. As evidence, one of them shows two videos taken on Pixel 2 XL before and after the upgrade to Android 8.1 DP2. In addition, Google has corrected a bug with insensitive sensor zones, which also attracted attention some time ago. Other visible changes include new navigation buttons that prevent burn-out of the screen, work with a microphone from the Bluetooth accessory with Google Assistant, increased camera start-up and capture speed, saturated display color mode (although some parameters are still at an unacceptable level). When the full release of Android 8.1 Oreo, is still unknown.
