another bug/issue i've discovered this weekend. and first i thought i was imagining, but it happened again...
while using a GPS activity, i often like to use the hotkey to return to my widget (eg, see my main watch face or check out the weather widget to see UV level/temp)> when i do this on the 945LTE, i have now seen on 2 out of 2 occasions that the watch seems to turn of the GPS radio and stop collecting distance/speed/pace information.
this happened during both a bike ride and a walk.
this is not what would happen on my 935. i could go to my widgets and the GPS activity would run in the background collecting speed/distance/pace info.
