Come on DJI, a little fore thought would have solved this issue. With a max. width of 8.5mm, we now need to remove our cases to use the TX! Some cases, like mine, are tough to get off.........You could have made the tolerance wider and added rubber shims to make up the difference if need be. Who are you all consulting with? I have the thinnest case made for my note 5 and its still not thin enough. The correct implementation would have cost you zero extra dollars. You went ahead and made a respectful, quick access quad only to hamper the phone integration.......Try to offer aftermarket arms that solve this oversight.
