I have previously put an app icon over another (on this Asus Zenpad 3S 10) and a folder was created with both of them inside. Then I was able to put other icons over that folder and they also went inside of it.
However, I now am unable to combine icons into a folder. If I move an icon I want to combine into a folder over another app icon, the other app moves away. It doesn't matter how many times I move one app icon over another, the one I am hovering another app icon over, always goes quickly right or left. Is there some alternate way to combine app icons that doesn't have a bug?
