I have no idea but, I don't think so due to the on and off switches and charge slots would have to be in the same place as the Ipads have and I would doubt other tablets would be in the same location.
I believe 2 and 3 are same dimensions. Thus, it will fit. It was designed for 2; I just have not examined 3 but, I have been told the size of 3 is the exact size as 2.
