Just a few weeks ago, WhatsApp stopped supporting Microsoft's mobile operating system - Windows
So, if your smartphone is running iOS 7 orAndroid 2.3.7 (and below), and you constantly use the application from Facebook for communication, then you should think about updating your device. The thing is that starting from February 1, 2020, WhatsApp will stop working on the above versions of operating systems from Apple and Google.
But if your device still has more recentversions of mobile operating systems and at the same time your smartphone is also equipped with an AMOLED display, you can begin to rejoice. Recently, WhatsApp has been tightly testing the dark mode, which means only one thing - very soon the application will receive its support and your smartphone will be able to work even longer from a single charge due to the optimization of the color profile of the application.
