The compartment containing the eyesight cameras makes a ticking/creaking noise that's annoying. If I only listened to loud music, I may never notice it, but I listen to audiobooks and podcasts and it gets annoying. Planning on taking it in soon to get fixed. I noticed that if I tap on the unit, the noise will go away for a while (melted glue making something loose? Or perhaps a rodent living in there 😂)
