The Note 10 plus and S9+ speaker turns up automatically when talking on the phone, nevertheless it is the same for normal call and whatsapp call too which is so wierd!
Tried to clear the cache - same Issue
Turned on Safe mode - No issue
Deleted teams app in Work Profile - No Issue.
The solution cannot be delete #Teams in work profile!!!
Knox security enabled for samsung phone for work profile which companies believe secured.
I request you to please fix this bug.
"Turned on Safe mode - No issue"
This means one of your third-party apps is causing the issue. I heard one of the Microsoft apps could cause the issue. Do you have any Microsoft apps installed?
