Until now, the Google Pixel Launcher used to automatically adjust dark/light themes on the basis of the wallpaper colour but Android Police has reported that in future Android builds, Google might roll out a feature with which users can manually choose the theme regardless of the colour of the wallpaper. The Pixel Launcher was introduced with Pixel 2 and Pixel 2 XL in October 2017.
The development was first spotted by Android Police which noticed that in March a user added an issue in the Issue Tracker apparently seeking manual controls to toggle between dark and light themes. A Googler marked this issue as “FIXED” and added a comment saying, “We have added support for a Dark theme to be applied to quick settings and launcher under Settings -> Display -> Device Theme. It will be available in a future Android build.” However it is not clear whether the feature will come in the next Android P beta update.
The development comes amid Google Pixel 3 XL leaked images which suggest that the new Pixel phones will have a notch on top of the display and a rather thick chin at the bottom and may sport an all-glass back. The Google Pixel 3 XL is expected to be powered by a Qualcomm Snapdragon 845 processor, and offer 4GB of RAM with 128GB of non-expandable storage. The 6.2-inch display will most likely feature a wide notch on the top and a thick chin at the bottom.
