This is a general issue with the Android default of having only 15 Volume levels - a silly decision I think. This can be changed in a config, but as a user root-access would be needed.
Please provide access to this setting or increase the default to 25 or so.
File “system.prop” entry “ro.config.media_vol_steps=15” (might be different on Android 14?).
This is really easy. I had this changed manually on my old phone, but as the devices get more important I do not want to root mine just for volume settings.
The widged is not really a solution when using BT, as the phone is somewhere and the access requires unlocking the phone and using the touch screen. Plus on my current headset the steps are about 6%, so not really finer.
The low settings are especially important when the speakers are potent.
