Strange beep sound through earpiece when getting a call

[Bladery]

Hey guys,

Since 11.1 or 11.2 (cannot remember) I noticed a beep sound through the earpiece when I get a call.
The sound appears between the pause of the vibration pattern. I have the vibration “accent” enabled.
I noticed too that the pause at “accent” is longer than before 11.1 (or 11.2) (at first there is a very quick vibration, then pause, then a long vibration).

Can anyone confirm the same behavior?

Thanks!

What earpiece, exactly?

When you hold it on your ear, e.g for a phone call

You heard a "beep", wondered where it came from, and held the iPhone up to your ear (as if on a call) when receiving a call and determined that it was from that particular earpiece and not the handsfree speaker?

Yeah exactly.
I noticed a quiet beep and was wondering where it came from.
The next call I hold the phone to my ear and noticed that the beep comes from there.
