Google is currently looking into an issue with the "double tap to wake" feature on the Pixel and the Pixel XL. Due to the reports of numerous Pixel owners reporting that there are issues with the double tap and lift to wake features that were recently introduced to the Pixel and Pixel XL via the Android 7.1.1 update.

The response from the Google representative does not go into any further detail on the issue other than recognizing that some users are experiencing the issue; the team is investigating and working towards a future update. However, the issue being noted by users seems to revolve around the general inconsistency of the features.

Sometimes it works and sometimes it won't or that there is sometimes a delay between the activation and response of the feature. At the moment, there are no details on when such a fix will come through, but if you have been experiencing the issue, then you can at least take some solace from knowing that Google is aware of the issue and is looking to remedy it at some point in the future.

It's just a couple of days back when it was reported that a gentleman named Mark Buckman had gone through four Google Pixel XL's because of a problem with audio on all of the units. At volume high levels the sound was distorted and full of static. Google Pixel devices audio issue can be solved by flashing custom ROMs after rooting the device.

Unlock the Boot loader first by connecting the device to a PC and enabling Developer Options and USB debugging in the setting. ADB and Fast boost software are required on PC for doing so. Then Install the TWRP recovery image. Flash the device with WETA Audio mod for pixel. An expert suggests to not root the device unless one is an expert on the matter.
