It is currently June 21, 2020... And I have the same problem with my Samsung Gear s3 watch... I'm on the yellow screen that says "Let's go" Tap to continue is the message on my phone... I CAN'T continue bcuz it requires touch screen function. Uggh!! This is sooooo annoying 🙄 Anyone with a quick fix WITHOUT turning watch back in to 1800 Samsung?
Do a factory reset of the watch, a normal reset still leaves some data behind. Here's a link to a Verizon article, it's the same across the board. "Samsung Gear S3 frontier / Gear S3 classic - Factory Data Reset (Powered Off) | Verizon" https://www.verizon.com/support/knowledge-base-211637/
