I can't say I ever really take my phone in the bathroom. I have a walk-in shower and don't really need to use my phone when I am taking a shower so it always stays away from the bathroom.
My kids have been known to take their phones into the bathroom to watch YouTube and they leave it at a distance. So far no issues but I do tell them that it may cause issues.
