Dubbed Dialer, the app is said to be developed by the Microsoft team responsible for Skype and is currently being field-tested in India. Judging from the screenshot we laid our eyes one, Microsoft Dialer looks just like your average Android dialer app if we've ever seen one. Still, Redmond's solution might come with a few interesting features: it won't be merely a phone replacement app, but will also enable users to call other parties via cellular networks, 2G and 3G ones included.
The other party will also need to have the app installed for this feature to work, of course. If they don't, you can still call them the old-fashioned way. Additionally, Microsoft Dialer will allow its users to search for people's or nearby's venues phone numbers and give them a call from within the app. You will also be able to block spam callers on the fly, since the app will be fetching real-time information about the person calling you.
The app is allegedly coming in the first half of December 2015, but rumor has it Microsoft will be releasing a public beta sometime next month.
