6. Troubleshooting
6.1 Phone Not Securely Held
- Issue: The smartphone feels loose or slips out of the clamp.
- Solution: Ensure your phone's width is within the 6cm to 9cm range. Press the release button fully to extend the clamp, insert the phone, and then release the button to allow the clamp to grip firmly. Verify that the phone is centered and the silicone pads are making full contact.
6.2 Difficulty Rotating the Holder
- Issue: The 360-degree rotation or Z-axis adjustment feels stiff or difficult.
- Solution: Ensure no debris is obstructing the rotating mechanism. Apply gentle, even pressure when rotating. If the issue persists, contact customer support.
6.3 Accessories Not Fitting Cold Shoe Mounts
