I have an Asus tablet with Lollipop on it.
Two week ago I was able to create another user on that device. Now I want to edit another user but touching the lowermost bar does not start any action. (the text is greyed out, i don't know, if that was the case also two weeks ago)
I already contacted Asus support and they said, this feature had been removed by Anroid and they can't do anything.
I checked the build.prop and it does not contain a single entry for fw.xxx
Any idea, why I can't add another user?
