hi~all! I am new with Galaxy watch 3, and I am not really sure if we can use the watch to swap the door scurrility system. I googled everything from the net, and found the SAMSUNG PAY app can actually do that, but I can not find anything from my phone. By the way, I am using Huawei mate 20x. Does anyone can help me on this case, if i can install any app to solve this problem. Thank you!
