I own the model GPR-H1000-9ER Please add an option to only measure heart rate during activities. Wrist detection is way too sensitive and sometimes thinks the watch band is my wrist, thus shining the laser into the room when I want to sleep without wearing the watch (might be because it is the yellow variant of the watch?). It's weird that stopwatch and timer can not be left running in the background. It's annoying that the timer can't be adjusted more quickly by holding down the buttons.

3 stars only, because app constantly disconnects, despite being set to 3 min connection time and the mission log doesnt work properly...sometimes it shows the map and sometimes it just stays blank and says "calculating, calculating, calculating"... since the mission log is one of the reasons i bought this watch, it's basically useless most of the time...

I mainly use two functions: 1. phone finder 2. automatic time synchronization both have the same problem. After not being in use for a while, the app doesn't connect automatically to my phone hence, when I need to find my phone it doesn't work. Time synchronization is the same problem. I checked my app permissions and it has all permissions to work in the background. Any recommendations to get that fixed?
