Review on 📱 Skywin USB-C Phone Docking Station | Samsung Dex Mode Compatible - 4K Dex Station Adapter with 2X USB 3.0, SD/TF Card Reader by Zack Frazier

This appears to be a complete replacement for the Samsung DEX device. Mine worked with my Samsung Galaxy 9 with no issues. However, there is a small caveat: you have to remove all covers to plug in the port (USB-C). The device has a narrow groove on the front that isn't big enough to accommodate cases. Protective films are ok. I've used them a few times as a complete table replacement and they've worked great. A memory card has even been added to allow for permanent storage. In short, it looks great, fits great and works great.
