Almost every time I look at my home screen on my Galaxy 5 it comes up with the screen of a different app. Unless that's the way it's supposed to work I thought that if you went to your watch to see what time it was it would default to the clock or is there an adjustment that needs to be made since the last update. I don't remember my Galaxy 4 doing that or in fact the Galaxy 5 doing that until recently.
Thank you for reaching out. I can definitely understand how this can be confusing, and I would be happy to look into this further for you. The default screen on your watch should be your watch face, as you are not seeing your watch face I would recommend resetting your watch.
