When I installed Android 10 back in November on my Mate 20x , the volte indicator field was turned off . But volte still appeared to work correctly, meaning I could surf and voice call for example simultaneously. When I rolled back to Android 9.1 , the field within this app said volte was active. Was wondering if this situation is unique to my device running Android 10 or others as well,.or possibly it could be app issue. Screenshots attached.
