This issue didn't appear for me until I got a Samsung Gear S3 Frontier watch. A week later my phone started randomly refreshing. Usually while using Facebook or trying to type something into a text field. Super annoying.
Hey, @user2Eh75sNhwS. I just wanted to reach back out and see if you were able to get this fixed up! If not, please let the Community know so that they can look into different ideas to help further.
This is happening with my S7 also. It's very constant. I never have bluetooth on, and it happens randomly but often. I've searched all over messageboards with no luck.
My keyboard just disappears right in the middle of typing.
My screen goes black for like 5 seconds.
My app page refreshes to the top.
