The iOttie Easy One Touch 4 can universally hold all phones and even many with cases between 2.3 and 3.5 inches. It features a mounting system which can lock or release the device with one… easy touch. It fits bars from 20 to 34mm in diameter and is fully adjustable allowing you to rotate it 360 degrees with the ability to view in landscape or portrait mode.
iOttie also includes a one-year warranty with this phone mount. While this product only has a few reviews on Amazon, iOttie mounts for automobiles have numerous well-rated ones that should be assuring enough to give this one a try.
