# UI Customization

## How can I change/hide the spinner which shows during document scanning?

You can change/hide the loading bar which is shown during document scanning. The detailed steps can be found in [this link](/_articles/extended-usage/ui-customization.md#loading-bar-and-backdrop){:target="_blank"}.

> Note: there is a known issue in v17.3, if you cannot hide the loading bar with the above method, please refer to this [link](/_articles/faq/unable-hide-loading-bar.md).
