Review on 🔌 Enhanced Samsung DeX USB-C to HDMI Cable - Black (Model: EE-I3100FBEGWW) by Nick Mitchell

Some Samsung devices are not compatible with DEX. For example 2019 A tablets. That was disappointing but the cable works great with DEX enabled devices like the Galaxy S21 Ultra. Works perfectly with my cell phone. I found an alternative to my tablet called "Kiosk Mode" on 42Gears Google Play Store that allows you to use any old Android tablet as a kiosk on a touchscreen monitor. In this way you can lock settings and applications, as well as create your own menu and directory. It's much more customizable than the Samsung DEX. Worth a try if this cable didn't help you use your device as a kiosk.
