Is the bottom the receiver for answering calls?
Then what purpose does the top mic serve?

Noise cancellation. Additional mic for speaker phone. Mic for video recording. Any or all of those...

Phones have had 2 or 3 microphones on them depending on model for years.

Simplest explanation is to improve audio quality by having multiple audio sources things like noise cancellation are much easier.

It's also so you can get stereo sound when you record video.
