WhatsApp keeps testing new features in the Android Beta version, and after endless refinements, they are made available on the stable release. Similarly, WhatsApp Beta 2.19.83 brings features like fingerprint authentication and ‘dark mode’. The Facebook-owned company is working on these features since a while now, and we soon expect it on the stable version.
Earlier last month, Facebook Messenger received the dark mode, and now it appears, the company is planning to induce the same feature on WhatsApp.
According to screenshots shared by the beta tracker WABetaInfo, the new ‘dark mode’ completely changes the look and feel of the app. It is limited to the Settings menu of the app and uses a dark grey background colour. It means AMOLED displays won’t be able to save battery effectively as they require pure black colours.
Fingerprint Authentication feature is also present in the new update. Users can enable it in Settings >Account >Privacy > Use Fingerprint to Unlock after registering your fingerprint. WhatsApp also gives users an option for a timeout after 1 minute, 10 minutes or 30 minutes. As like of Android system, too many failed attempts will lock out the app for a few minutes. The same feature is already available on iOS devices since the past year, apart from fingerprint authentication, users can also unlock using facial recognition via Face ID.
The new features needs some refinement before being made available on the stable build. Currently, both the features are limited to some users on the latest WhatsApp Beta version.
