iPhone SE Clicking Noise

I have the new iPhone SE, and when I open either my camera app or Snapchat, a little clicking noise (like a quiet shuttering noise of taking a photo) will happen. If i close the app and reopen it, it won’t make the noise, but it will after you wait a few seconds and reopen an app. I’m on IOS 14 and i’m not sure if this is a known or fixable problem, but it’s been happening for about a day and i’ve never known for it to happen. Age shouldn’t be the problem since the phone is only about 4 months old. Please help!!
