Just taken it and the GT31 for a cycle ride. Phone display turned off for the whole duration.
Red GT31 Yellow pixie3
Certainly has fixed the display off syndrome!!!!! Speed talk worked the whole time as well. So we can now save a bit of battery by leaving the display off, and just turn it on when you want to check results.
Great stuff Manfred.
Haven't seen anything else new so far, may take it for a sail this arvo if the wind gets strong enough.
