I've been using the DJI Mic 2 since it came out and it has never let me down. I mainly use it with my Lumix S5II and Osmo Pocket 3, but lately I've found myself shooting more frequently with my phone.
You can, of course, use the Mic 2 (and newer models) with your phone, but the solutions aren't exactly ideal. There are two ways to do so: you can either connect directly to the phone over Bluetooth or you can use the on-camera receiver connected to your phone's USB port.
