After that, you'll be able to create channels for your conversation, connect to a nearby friend's watch and talk by pressing a big mic button at the center of the screen. Samsung also recommends using and running the app for the first time while that watch is connected to a smartphone. To be able to use the feature, you need to log into your Samsung account on a phone connected to your watch. Provided you know other people who have a Watch 4, of course, unless Samsung decides to roll the app out for its previous wearable. Using Flow, you can transfer activities to the device best suited for it, or pause it and get back to it when you have more time. That said, the app's Google Play description says "two or more users" can have instant conversations, so you may be able to use the app outside of secret one-on-one chats in the middle of the night. Also, Samsung Flow intelligently senses the data connection status of your Galaxy TabPro S and automatically sets up a Wi-Fi hotspot on your mobile device when needed.
That would limit the number of friends you can chat with, since they also need to own the latest Galaxy Watch. By "smartwatches," though, we really just mean the Galaxy Watch 4 and Watch 4 Classic - the app, first spotted by XDA-Developers, only works with the tech giant's latest wearables and isn't compatible with any of their predecessors. Samsung has launched a walkie talkie app for its smartwatches similar to Apple's, giving you a way to chat with friends without having to make a call.
