iPhone 15/16 ear speaker quality compared to iPhone 12
I'm currently using an iPhone 12 and I'm considering upgrading to an iPhone 15 or a 16 standard version. The 12 has the speaker on the notch whereas the 15 or 16 have the speaker in a "slit" at the top of the screen. Is the speaker for the ear any good on the 15 or 16 when making or receiving a telephone call? How does it compare to the 12?
I noticed when making a call with a 15/16 of a client, I could barely hear the answering machine. There was only a little background noise. I checked the speaker's volume and it was set to maximum. The online reviews of these phones have focussed on the dynamic island and screen, USB-C charging, camera, AI, etc. But there is little information on the things that make the telephone function, the ear speaker and the microphone.
Thank you.
