Introduction Android 10 brings us lots of new features. In my opinion, one of the most interesting is the Dark theme. Most likely everyone would agree that using very bright applications at night is uncomfortable. Some apps support more eye-friendly themes at night, but every application needs to be configured separately. Wouldn’t it be great to make the system and apps dark with a single click or even have it turned on automatically? Well, Android 10 makes it much more user-friendly both for the end-user and the developer.
