Nighttime will provide some relief to our eyes using the Voice app if Facebook's proprietary messaging platform applies its 'deep mood'.
Rumors have been removed for such a long time, but the news has been confirmed by the so-called interface that this feature is under development and will be available to all voices users.
Deep mode, as the name suggests, turns white background into black, which is more comfortable than the eyes. Mode also helps in increasing battery life.
Android phones will be beneficial with the OLED display panel, because they will feature Dark Mode in faster calls than other screens.
