Almost all smartphones I've tested with a Samsung Galaxy Note 9 (6.4" screen) with a protective case (not bulky like Otterbox or equivalent) will do. Or without a protective case. I have also tested with Samsung Galaxy S8 (5.8" screen) too. It feels more secure when the smartphone is clamped. It has 2 tripod mounts with standard 1/4 x 20mm female thread, which works in portrait mode (vertical) or landscape (horizontal) can be mounted made of plastic and the smartphone clips are rubber on both sides. Normally these are not heavy designs. How friendly. Would buy again. Great job.
