The feature has already been spotted on the version 2.19.74 of WhatsApp Beta Android.
"If you use one of these affected mobile devices, we recommend upgrading to a newer Android, iPhone, or Windows Phone to continue using WhatsApp".
Excited? The news on what new features WhatsApp will put on their phones next is enough to keep WhatsApper's waiting for the new update. Also in Windows 10, we have a dark mode, in addition to having a dark mode in major browsers such as Chrome, Firefox, and Safari. This will also help the receiver know if the message is a simple one-time forward or a viral message that has been forwarded multiple times before hitting his phone.
Popular messaging app WhatsApp announced on Wednesday to withdraw support for all smartphones running on Windows operating systems soon and would stop working on Windows phone after December 2019. When activated, the interface of the network, app or platform that we are using happens to have a dark tone and the level of brightness is considerably reduced, something beneficial for the human eye especially in low light conditions. As the name suggests, this feature will allow users to open links within the apps rather than requiring them to leave the app. Do take this information with a pinch of salt, and stay tuned for more information about the progress of the above mentioned features.
