====Why are we doing this?
A few iPhone X users with OLED screens have requested a way to have a black dark mode, so that they can benefit from energy saving. Additionally, some iPhone X users have requested this feature for aesthetic reasons, as the bezel around the screen of the iPhone X is a true black. Additionally, this feature will soon be available on Android.
====Proposed Design
**Changing themes**
Users will be able to select black mode from the appearance theme selector in the Article view or in settings.
