Unable to combine desktop icons into a folder on Android 7.0 Asus Zenpad 3s 10
Just got mine today and had the same problem. It took a bit of fidgeting, but I figured it out. Drag one of the desired icons to the static toolbar at the bottom and then drag whatever remaining icons you wish to group into that first icon. You kind of have to release immediately so it stays in that "folder" you created. This worked for me, so I hope it works for you.
