Still same problem
Make a incoming or outgoing active call and hear the audio loudness without speaker enable
No Use.. same issue after did this, even I clear the call history also..
From last update of oneplus 7 Pro (10.3.7) I can see phone call audio loud without loud speaker enable.
So I can't without earphone. And...
Battery drain very fast after update 10
3.6 in one plus 7pro
