I ditched the phone and went with a Galaxy watch with a cell plan. Service is only $10/month, and in addition to using it for Strava I can make calls/texts if I ever have an issue. Also waterproof.
I have the Active 2...can't get the Strava app to work on it! Samsung Health tracks just fine, but doesn't connect to Strava or Trailforks...
Bought a quadlock case for mine. Have had a couple of off's and it's been solid. Only really use it for checking trailforks/gpx maps when out riding and it's easier than having to get the phone out of a backpack when out riding trails.
Basically ditto. With the rugged Otterbox case, it seems G2G.
