Sorryly i also have to add problems with the wifi. When i wan't to sync the watch tells me, that there are no wifi's configured. When Istart the watch, the actual time is shown on it, so somehow wlan is working when starting up.
After copying the a new wlan configuration file to the watch, the 2 runs it did were lost, this is the most annoying for me at the end.
For the GPS accuracy part I see the following problem - where constant with the last 2 versions: When I turn on my watch within WiFi but with no change to reach GPS, it takes about 5 minutes to come to a place where GPS is present (but i don't have WiFi there), i'm not getting any good fix, the fix is always coming for very short time and then gone, coming again - gone, ... . I always have to restart my watch and then wait for a fix (which is than done within one minute).
When I'm starting elsewhere where i have wifi + gps the watch + accuracy is fine.
