Iphone water indicators not pink, still possible water damage?

Hypothetically, if you got your iphone 4s wet, but the water indicators are not triggered at all, is it still possible the phone has water damage on the inside that apple would find if they took it apart?

My understanding is there's many indicators inside, its not just 1… So one may be fine while others may not.

  • Will my iPhone still work after water damage? It fell into a bucket of water last night and I can't turn the phone off because the screen is black. I can hear the phone ringing and vibrating, but can't see anything. I put it in a bowl of rice, is this fixable? Will the screen eventually work?
  • Possible water damage on iPhone 5s? Ok so I went hiking and I didn't have pockets, so I put my phone on my side between my shorts and skin. The hike was difficult so I ended up sweating and I totally forgot my phone was on my side instead of my backpack. As gross and stupid as it may sound, I think my phone has possible water damage from my sweat. However, the screen is still responsive and fine yet the home button does not work when I press it. However the fingerprint scan still works. Will putting it in rice help?
  • Possible iPhone water damage? I knocked a can of Dr Pepper onto my iPhone and it mainly went onto my screen however some of the liquid might have somehow got into my charging hole or earphone jack. It's being about 5 minutes and my phone is fine, however should i take any precautions like putting it in rice just incase? Or because it's fine should I leave it?
  • Possible iphone 5s water damage? Alright so i put my phone (speaker/outlet thing down) into a cupholder today and there was water in the bottom of it and now my phone turns off and won't turn back on any time i hit the sleep/lock button. Does this sound like water damage? If it does, do you know how i can fix it/dry it out? If it doesn't, do you know what might be wrong with it?
