With LTE Usually with a Carrier service like Verzion, AT&T, Sprint, T mobile and so on. Samsung will release the update. But your carrier would add some stuff and then release it to you
Yes, you're right, I did have a Pixel and was used to getting the updates on release day. Now I am back on Samsung Gear and forgot you have to wait for the carrier to approve it. Just got back from lunch and still no update. It may be afew days. I know you can check the Verizon update site and it will let you know what update is available.
