Hello, I recently misplaced my phone.
I have also faced the same issue on my Samsung Note 10+. When the incoming call comes, the sound is coming from only headset and not from the phone speaker. On the other hand, alarms also working the same way. I can listen the alarm sound on earphones but not on device speaker, who will put earphones while sleeping just to listen to the alarms? this issue is occuring only when bluetooth is connected, looking forward to fix the issue, thank you.
