Name TV IP address

Find it on the TV: Settings → General → Network → Network Status → IP Settings. Your phone must be on the same Wi-Fi.

Trust the TV once. The TV uses its own security certificate, so your browser has to approve it first. Open TV security page
If you see "Your connection is not private", tap Advanced → Proceed. A page of text or a blank page means it worked. Close that tab and come back.
Save & connect, then press Allow on the TV screen. If the browser asks to access devices on your local network, allow it.

Troubleshooting

Stuck on "Can't reach TV": repeat step 1 (trust the TV), check the IP, and make sure the TV is on.
Nothing happens on the TV: on the TV go to Settings → General → External Device Manager → Device Connection Manager, set Access Notification to First time only, and check this remote isn't on the Device List as denied.
Power on: this works only while the TV is in network standby. Turn on Settings → General → Network → Expert Settings → Power On with Mobile.
Works with Samsung Tizen TVs from 2018 onward.
