Sometimes the volume display for the "Call Volume" is not using up. I'm only use discord and fb messenger for calls. When I'm turning up the volume for "Call Volume" it doesn't show up. So i will restart my phone to fix it again then it will happen again and again.
Please tell me your discord and messenger app version.
When this problem is appearing, did you switched to any apps while voice calling at the same time?
How often does this problem appear?
About how long has the voice call went on, then this problem appeared?
Thank you 🙂
