I'm also facing the low volume issue from headphone jack, it's quite weak and terrible. It's quite useless headphone jack with this weak audio output.

And while the audio playing in background while phone is locked, the volume buttons are not responding, I have to turn off "show fingerprint icon when the screen is off".
I don't want to use lock button lot and it's quite inconvenient to press lock button to use fingerprint scanner. Pls make these better like other phones.

Please please please fix these simple issues.
