WhatsApp has bought the most-anticipated ‘dark mode’ into reality but this dark mode is accessible for only a certain group of users. This dark mode feature makes the app background dark black which alleviates the eye strain and helps the battery to stay longer time. This dark mode is introduced in the beta version of the application in android, hence only the android beta version users have the access to use the dark mode, hence after the testing in IOS version, the dark mode will be available to the general users.
