This phone holder was designed with measurements based on the Tesla Model S and the iPhone 8 with a slim cover, but it is quite universal.
It also fits the iPhone 8 Plus with a thick case and its overall design allows for larger phones and probably even similar dashboards (untested).
If the phone has a silicone/rubber case, it is enough so it doesn't slide around, otherwise, I would recommend glueing some foam, to have a tighter fit on the phone.
This design was intended to glue some foam on the "claws", this allows for a tight fit without denting the dashboard.
