Package worked on samsung s8. USB 3 working as 5 Gbit and Samsung DeX works good but needs to connect power supply. If not connected to power only screen mirrors. Power comes 5 v 2 amps with 9 volt charger. Becouse power used by Hub.
Dex on note 8 started immediately. Connectors are good, do not fall off. Metal hull. Made firmly, neatly. during work, not much heated, i think it's normal. The phone is not heated. Charging during operation supports, but not fast.
For this money, super offer.
I have just tested it for few minutes so will update my feedback once I use it for sometime. The description and everything is good. Delivery was OK as well as the packaging. The only thing you might have to remember is to 1-connect the adapter to phone 2-Connect HDMI to Adapter 3-Connect the charger to adapter.
Without charger it won't work in Samsung Dex Mode.
