Hi, So, I just received my first ever Tizen smartwatch yesterday - a Gear Sport currently running Tizen 3.0.0.2. I'm enjoying exploring this after having lived very happily with a Pebble Steel for about four years and I have a question about the Always On Display feature. It appears that the watch face always goes to black for a split second when transitioning between fully on and the low power display...going either way. Is this normal? (I also need to figure out how to upgrade it to Tizen 4.) Thanks in advance, folks!
