Google remains committed to providing Dark Mode in all of its applications. The latest is Google Play Books, which has been supported for this automatic system change on Android 10.
The case of Google Play Books is paradigmatic. The app has always allowed you to use a dark background with white text while reading books. However, the application’s user interface has always had a white theme.
With version 5.4.3 this has changed, and now the entire application will be dark. Of course, you can continue to customize your reading mode view to the theme you want.
At this moment I already have Play Books version 5.4.3 installed, and not yet I have the Dark Mode. This means that this is a change that will occur at server level, because there is still no way to switch between themes in the settings.
Update with Dark Mode gradually reaches users
As usual in this kind of changes, they don’t happen to everyone at the same time. Soon all users will be able to access this mode that is healthier for their eyes, but also for their battery.
Who reads a lot in the application, probably already used the dark mode. However, getting to the menu and having a completely white interface is a clear problem, which is solved.
