I might have damaged my audio quality of my iphone at some level by using hot blowdryer on it because i was delusional about steam entering from hot shower.

I used a hot hairdryer for 1 minute on the speaker, microphone, and earpiece of my iPhone 14 Pro Max, fearing that steam from a hot shower might have entered. Although the loudness of the speaker is fine, I have noticed slight distortion or crackling in the audio, which i think is my delusion. I am uncertain about how to confirm if any actual damage has occurred. However, I suspect that I may have caused harm or melting to some internal components with the hot air, leading to audio quality degradation. I feel like a lunatic for doing such a dumb action and am now wondering how to determine if there is any real damage.
