OP did say it was as loud as an alarm clock. Another member commented this:You didn't say this? I'm confused.
My home button has gotten quite loud, which is surprising because I do not jsut it much (I use 3D touch everywhere I can). I wouldn't say it's intolerable, but in a quiet room its clear that I am getting on my phone. I am otherwise happy and so I won't be expecting a replacement until something more serious arises.
And it was mistaken to be by the OP when it wasn't.
