Speaker too quiet during calls

Thinking of how to define the problem more … This screen recording is from an FP3 4.0-a15-20260612634536-community-FP3 … Settings > Sound and vibration … just a trial run (sound and video slightly out of sync)

My phone is acceptable but the video demonstrates that media volume is stronger than call volume.

Due to sync issues a recording became cluttered but one could also include ring volume which is clearly well in excess of either of the above.

Has anyone else mentioned increments?
On FP3

  • media and call both have 12 steps
  • other sounds 8 steps.
