Most phones should work with the holder. You will also need your own screws which should already be on your bike. You can also choose to use 1 screw on the holder (move the holder lower) to accommodate tablets. It is about 7 inches from the bottom slot on the holder to the bottom of the bike display if you use 1 screw, if you use 2 screws it would be about 4.5 inches. Dimensions are 6.5" x 3.5 " and 0.5" deep horizontally (165mm x 89mm and 12mm) and 6" x 3.5" and 0.5" deep vertically (150mm x 89mm and 12mm)
