I downloaded this app until edge Lighting + works. Tried many other ones but either were too complicated or didn't work. This one gave me a bit of a hard time at the beginning but checked the FB page of the developer and got it to work. If you don't have patience to wait for the official Samsung updated one, download it. Paid for the pro version 11aed. It works like a charms and serves the purpose.
The one we have no, it has to have a 5g sign stating that the chipset is there. It's around 250$ more expensive, and i personality would wait a couple of years till it's everywhere. Have an idea on how early we still are now
