I’ve had my 4s for around 2 weeks. The last two runs I’ve done have been very inaccurate and the gps has me running out over the water. It says I ran for 7km, though I ran for 6km and the pace is wildly erratic, fluctuating between my average 6.20/km to 7.50/km to 3.25/km (I wish). I have regular GPS on, not GLONASS but this hasn’t been an issue thus far. Sleep tracking has also been an issue as it is not picking up when I get up in the night. Any ideas? I changed from the Fitbit Ionic as wanted a smaller, round watch and was frustrated that fitbit weren’t updating their model, but am left very frustrated.
