Dropped my glasses back there the first time out!
Weren't gonna get home without them. You need an L-shaped object to sweep the phone along to the end where you can see it. I used my Trailer broom with the handle short. It was just the right width to reach the front of the boxed area and sweep the glasses along to the end where I fished them out with a wire coat hangar bent into a small hook at the end. You could also use a wire coathangar bent into an L shape to sweep the space. If you can't hook the phone, get some duct tape and make a big enough pad on the end of the wire that the phone will stick to when you capture it. Now I put my glasses in the night table drawer, not on top!
Let us know if you are successful!
