Review on 4K Portable Dock - USB C to HDMI Adapter with PD Charger, QCEs USB-C Multiport Hub for Samsung Dex Station, Galaxy S20, S10+, S9, S8 Plus, Note 10/9, Tab S4, MacBook Pro/Air 2019, iPad Pro by Matthew Owens

Quality product with a solid connector and housing. DEX works on my Samsung S9+. The only problem is that when I plug my phone into the adapter, I also have to unplug and plug the USB mouse back in to get the mouse working again. Worked with WiFi USB without problems. USB-C must be connected to enable DEX. Also works great with HDMI to VGA converter. I've tried various DEX devices with different peripheral port configurations and I like this one best for my desktop. Basically a good device.
