Been running the Wm100 since the 1st batch came over on the Mayflower. My dusk/dawn setting ran fine till yesterday.
My Samsung Galaxy S5 phone didn't like being in the cup holder on the mower in the rain and finally croaked.
Yesterday, the wife slipped down to the store and got me a new Samsung Galaxy J7. Now, my outdoor lights are on and the sun has been up for over an hour.
Looks like there's something with the different android devices that's causing this anomaly.
