Did the wind cause my smartphone to go on hold?

Probably not; however, in protecting your face from the wind, it’s possible you accidentally hit the hold button with your cheek, chin, or a finger.

I don’t have any other explanation either, but I feel pretty damn sure the wind didn’t cause your problem

@SEKA Oh. It was outside in the middle of winter. Could it have been the cold or dust/snow or sweat?

^ It could have been the cold or dust/snow or sweat, but that is as unlikely as the wind
