No, Alexander, you are wrong. Representations of the phone will be limited to one in each mirror because you have given only one mirror in each of the x,y, and z planes. There are no multiple reflections unless superior peripheral vision is included. Those are representations only anyhow. There is, definitely, only One phone. You did not include reflections or anything beyond in the problem statement.

If you have almost parallel mirrors and stand between there will be infinite regression. You have no parallel mirrors. Your problem as stated allows only one physical phone. Reflections do not count. I am not fooled.
