Use the VidPro CL-2 Phone Clamp Tripod Mount to solidly and securely hold your smartphone and mount it to a tripod, monopod, selfie-stick, or any other support system with a 1/4'-20 mount. For your convenience, there are mounts on the bottom and the back so you have options for how your phone is orientated for the best shot. Its combination of spring-loaded clamp and padding on the grip holds the phone firmly in place while allowing it to adjust from 2.5 to 4 inches, so it will hold just about any smartphone even if it's in a case. One end of the clamp has a cold-shoe mount for accessories like video lights or mics.
