The way you turn of 6G on Samsung is via Settings/Connections/Mobile Networks/Network mode. Here you can choose any of the 4G or 5G options to prevent the phone from attempting to connect to any 6G network. This is not that hard to do, and it’s definitely the type of thing that will offer you the benefits and quality you want. It’s a great idea to try this out, because it’s well worth it.
You can try to adjust the network manually, but if you set it automatically, then the network will try to do the 6G connection first. That’s why you want to connect manually and ensure that the 6G connection is blocked. It’s a bit of a tricky situation at first, but it will certainly offer the benefits and quality that you want, so keep that in mind and the benefits can shine all the time. That’s why you have to give it a try for yourself, and in the end that’s what will make the experience better.
