Sony’s small apps feature is one of the cool feature of its UI which serves a purpose of multitasking in same screen without switching off another app from main screen. At present there are many stock small apps provided by Sony and some small apps are available on Play Store also. As you are all aware that right corner soft key is used for accessing recent apps opened by the user and at present there is no other option than that to access that functionality.
