Hi @DearZack,

When the MarkerPointer is dragged quickly toward the start or end of the range in SfRadialGauge, the gesture may move outside the touch boundary, causing the pointer to stop before reaching the full range and become unresponsive. However, we have already considered this as an improvement and logged feature request for it in our feedback portal.

We will prioritize the features of every release based on demand and priority. So, this feature will be available in any of our upcoming releases. You can also track the status of the feature using the feedback link below.

Praveen Balu.
