Did the holder bought to replace my lost Samsung mount ... but I'll send you back there now since the Grade 3 apparently for holding a ticking is too heavy, and by the rather long "arm" of the mount the device itself to wiggle extremely at the lowest speeds begins ... For navigation or "dashcam" shots with the phone so that's totally inappropriate. I now have all sent back and brought me according to the Samsung support. This is fixed and stable and there also nothing wobbles. Even at higher speeds.
