Anker - USB C Hub (5-in-1), 4K@30Hz HDMI USB Hub with 90W Max Power Delivery - Gray

Based on the information provided in the knowledge base, it is not explicitly mentioned whether the specific USB-C Hub (5-in-1) supports Samsung Dex on a Galaxy S10+. For Samsung Dex functionality, the host device typically needs to support DisplayPort Alt Mode via the USB-C port. You may want to confirm that your Galaxy S10+ supports DisplayPort Alt Mode through its USB-C port. If it does, and the hub itself meets the technical requirements of DisplayPort Alt Mode, it should work with Samsung Dex. However, this specific hub's ability to support Samsung Dex isn't explicitly stated in the available documentation.
