So I have upgraded my OS to Android 4.4.2 today (I'm using Lenovo S820) and while scrolling through the apps, I accidentally moved one app over another, creating a folder. I want to undo it now.
I've tried long pressing the apps (inside the folder) and move them on all parts of the screen to get them out, yet it isn't working. It is not going out of the folder. I have not seen trash bins or any signs indicating a way to remove the apps/folders.
Please, please help me to fix this. Would also appreciate if you teach me how to delete the app folders once I get the apps out.
