Resolution Note:
By design: project has disabled Depth and Stencil buffers in Android player settings. Depth buffer is required for correct 3d objects occluding, otherwise it depends on drawing order.
The missing object has assigned a material which draws it during opaque render pass. Scene has enabled skybox, which is drawn after opaque pass, because depth buffer is disabled and Z testing is not available, skybox overwrites the entire screen, making previous objects disappear.
Options to workaround that:
1. Enable depth & stencil buffer for Android
2. Explicitly specify objects rendering order to be after skybox pass.
