So I picked up a 5s from someone on CL and everything is great so far except for one thing. The vibrator is so obnoxiously loud and strong that it actually annoys me. Has anyone ever had an iPhone with a extra strong vibrator? (Not making a joke here!) I wonder if Apple would replace this with a different one. I seriously couldn't take this device into a meeting because if it went off it would cause heads to turn, it's that loud.
