Feature phones that run android will lack an accelerometer, might lack a camera, but any phone without a microphone would certainly be strange.

Nonetheless, there's nothing preventing a system bus from reporting that a virtual device exists, even if there's no physical hardware to match. Besides, as soon as you plug a headset into the audio jack, the microphone becomes available.

You can reason about what kind of device is this and in general basically look for statistical patterns. Which is what they seem to be pretty good at. If you have modified device then it's likely that you are an outlier.

I doubt all devices are constantly reporting their capabilities to the NSA so they can look for outliers.
