Has anyone found out how to fix it ? And this may sound weird but what color are your note 9's. I have a purple and the issue only is happening on my phone and not my husbands blue note.
If I am not wrong, this feature to shut off the top speaker when the promixity sensor senses something near, is actually to protect the phone user's hearing. Many times I have put the phone on speaker mode during calls to listen to automated voice answering, and then out of habit put the phone to my ear to speak when I get connected to a human. This feature to shut off the top speaker automatically when i put the phone to my ear is a blessing for me as I will never remember to turn the speaker off.
Wow thank you for that advice I think somebody has figured this out it is a protection feature! If your phone is on speaker and you put your phone to your ear the proximity sensor shut the top firing speaker off to protect your hearing and then when you pull the phone away from your head after a few seconds it will kick back on that is why it seems like it's going on and off thank you so much whoever figured that out
I am facing a similar issue. Initially the speaker would work fine - now when I am on a call - the speaker goes off while the phone is still in the speaker mode ! ... It's a bug / issue with the hardware it seems !
