4. 操作步骤
   安卓或iOS端选项无法下拉选择最后的几个选项，PC网页没问题

Start by reproducing the provided Select schema on both Android and iOS, focusing on scrolling to the final options; compare this with the working PC behavior. Trace the mobile Select entry point used by the SDK and verify the fix by confirming every option can be reached and selected on both mobile platforms.
