If you have a pop socket, you definitely have to remove it to get the phone to fit. If you have a slim silicone case, it'll fit but only barely (they need to make the feet stick out a little more). Overall, it was a waste for me. I didn't know you had to set it to where it's leaning directly on the dash (so it's either directly covering a vent or a good portion of the clock screen. It was shaking a lot, so I removed it to set it further back and it no longer stuck, kept falling off. I already threw out the box so I can't return it. I didn't want an obnoxious one to put on my windshield and thought this would be a good solution. Disappointed.
