WhatsApp is finally getting a new dark mode on iOS and Android today. After months of beta testing on both mobile operating systems, the WhatsApp dark mode will be available for all users today. If you already have dark mode enabled at the system level on iOS 13 or Android 10, then WhatsApp will automatically switch over. Android 9 users can simply enable a new dark theme in the WhatsApp settings menu.
Facebook has tweaked its WhatsApp dark mode to ensure it lowers the brightness of a phone display. “During testing we found that combining pure black and white creates high contrast that can lead to eye fatigue,” explains a WhatsApp spokesperson. “So instead, you’ll notice a special dark gray background and off-white color that lowers the brightness of the screen, cuts down the glare, and improves contrast and readability.”
You can download the latest WhatsApp update from Apple’s App Store or the Google Play Store to get the new dark mode option.
