after 8901.4.A.0016.6 update every incoming and outgoing phonecall is at the maximum volume: but this happens just if you (like me) set the call volume at minimum.
During the phonecall the volume level on the control slider is showing as desired at the minimum even if the phonecall is at maximum (ringing, talking, etc).
The volume doesn’t lower down pressing VOL-, you have to press VOL+: after that the volume will be at “+1” (the first step to the minimum value) and pressing VOL- it will returns at minimum volume. But just until the next call…
Tested both with or without wired earbuds.
My workaround at the moment is to keep the call volume at “+1” from the minimum.
Clearing cache and storage of the “Phone App”, “CallFeatureSetting”, “Carrier Services”, “CallManagement” does not solve the problem.
Thanks in advance for your suggestions!
as for the “hard reset” suggestions… I’ll keep that as the very very very last option
