Let me express my disappointment with earpiece speaker in Samsung Galaxy S21 FE. The sound is not clear. I can't easily distnguish words of my interlocutor during a phone call. The same audio is much better when played on loudspeaker or any external device, e.g. headphones.
I can see that the earpiece speaker is much smaller than it used to be in smartphones models from a few years ago. It may be a reason for poorer sound quality.
