I recently purchase the gear sport. After a few days I noticed my sport was missing the messaging application. Further more their was no way for me to view text message conversation on my sport. How ever when using a watch face with a messaging shortcut the messages application opens and can be closed from recent apps. It still will not show an application in the app list however. Another app I can't seem to find is an email app.
I have contacted Samsung over a week ago with this issue and are yet to hear back from them. If any one has the same issue or a solution I am all ears.
