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 Ryan Vaughn

Connected to my Galaxy Note 9, screen sharing and Samsung DeX are working fine. until it seemingly randomly loses the connection. The phone and key are on the table, not moving, and no one is touching them or even breathing next to them. Disconnecting and reconnecting does not improve the connection, it works less than a minute, after which the connection is lost. This is very annoying as it disrupts the workflow and forces you to restart applications.
