Dark mode is on trend next to notch display and folding smartphones. So Google has been taking small steps toward supporting dark mode.
In past, we have seen YouTube, Phone, the Pixel Launcher, Google News, Contacts, Messages and some parts of the Maps app get a darker theme.
Google disappoint many people after releasing Android Pie update who are hoping the system-wide dark mode. Google may fulfill this wish in the upcoming Android Q. It may realize that darker colors can improve the battery life of OLED panels and less retina-searing.
A Googler (Lukasz Zbylut) post on the Chromium bug tracker states that:
Dark mode is an approved Q feature […] The Q team wants to ensure that all preloaded apps support dark mode natively. In order to ship dark mode successfully, we need all UI elements to be ideally themed dark by May 2019.
Google also ensures that all pre-loaded apps should get a dark mode by May 2019. That will the same month when Google debuts the preview of a new Android version to the developer.
It is expected that Dark Mode under will be under Settings -> Display -> Dark Mode in Q.
Adding fuel to the fire, Google has changed the permissions to the Chromium Bug Tracker, making it inaccessible to ordinary users. But Android Police has collected the full screenshot and shows to the public.
Here is the screenshot.
For the official confirmation, we have to count down till this year Google I/O.
