When looking through the list of installed applications I am able to search for an app by name quickly using PC keyboard on Genymotion emulator or when I plug in an USB keyboard to my Galaxy S2 through USB-on-the-go.
But I want to do the search on Galaxy S2 using soft keyboard. How to do this? I am pretty sure that I could do this with soft keyboard because the software "Wi-Fi keyboard" is able to do this. The question is only how to make a soft keyboard appear on the screen.
I have latest official firmware (Android 4.1.2, rooted) available for it.
