The latest preview did reveal that a single press and hold on the home button of your Android M smart gadget could open up Google Search. So no more swipes along the top of your home screens will be needed. A huge leap though is that Google Now is more sensitive to context thanks to Now On Tap. Using this feature, your phone will know what email you are dealing with or what music file you are accessing. Android M also means the arrival of Android Pay. We have heard about this since MWC in March this year but it is only now that users will be able to use apps for processing payments over an application or at stores.
