The Pixel 2 XL running Android R was exposed on Twitter. There are few details about Android R at this time. It is reported that Android R will improve the dark mode to cover more third-party applications while allowing users to adjust the time period for turning the dark mode on and off.
In addition, Google may improve the Bluetooth experience with Android R. It will support the sharing of larger files via Bluetooth, and Bluetooth will not be turned off when Airplane mode is turned on so that wireless Bluetooth headsets such as Pixel Buds can stay connected with Android R devices at all times.
Android R will be the last Android version received by Pixel 2 XL. As usual, Android R will be officially released at Google I/O.
