Does my iPhone 6S have water damage? Is there any other water damage sensors in the phone?

I got my iPhone 6S about a month ago and I love it. The phone is working perfectly, but the thing is last year I had an iPhone 5S and it got wet and the sensor inside went off. Apple then wouldn t replace it under the 1 year warranty. Well my iPhone 6s hasn't been dunked or anything but I took a shower and came out and the phone was covered in moisture:/ I know not smart. I also work out with the phone so sometimes it's sweaty. Do you think I set the moisture sensors off? I checked the one with the SIM card and it didn't go off. The phone works fine but do you think the inside ones show water damage?

Steam can set off the sensor. Don't take the phone into the bathroom during showers.

It's possible, I know several people who have had the Moisture Exposure Sensors inside the phone turn red/pink, due to shower steam, sweating while working out and just plain old high humidity. And yes it is possible that the one inside the phone as well as inside the headphone jack can be triggered and the one you are looking at not be.

The sensor is in where the sim card is. Use a paper clip to take out the sim card then use a flashlight to see if the sensor is triggered.
