Not sure if my phone has issue or not. Even I turned the in-call volume to max.
I already found the volume slider goes back to the default volume which near the middle at some point. I hate to keep turning the volume up all the time because it won't stay there. I found when I had my T-Mobile SIM in the phone it was never the case. Only with a Verizon SIM it's happening. Also seemed the same issue when I had my factory unlocked Note 9 on Sprint before.
Anyone has experience like that?
