A few days ago, the WABetaInfo site announced that WhatsApp is working for night mode version or you can say dark mode version for iOS and Android devices.
In recent months, we’ve seen several popular applications implement night mode, which reverses the colors of the application by leaving white letters on a black background. It enables users to use their eyes less, especially in dark environments.
Some applications that added this feature include Android Messages and Youtube in the Android version. In addition, Google has recently confirmed that the Android Call App will also include this useful feature.
I’m happy to exclusively give the good news: WhatsApp is finally working on a Dark Mode! It’s a dream 😍
There are many important secret references in recent updates!Be patient to see it out, hoping it will be FULL OLED friendly for Android phones, iPhone X and newer!
