With the Android 7 update of my Xperia Z5, the volume control of Bluetooth devices had become very unbalanced. The step from level 3 to 4 is much too large, it goes from a slightly too low volume to way too loud. Is this Android itself, or the Sony implementation? It was fine in Android 6.
I second this, a clear skip has appeared between volume levels 3 and 4. I can actually hear the volume to go up or down two levels at a time when i push the volume control buttons or adjust the volume slider on screen. I have a Z5C.
(When this is paired with the ridiculous logarithmical volume control on JBL Charge 2+ the issue is really annoying. The volume is basically either too low or too high all the time when used indoors.)

I'm using a z5 compact (E5803) and obviously having the same trouble you are experiencing... but i have a workaround: everytime i'm gonna connect a accesory (headset, car audio) I connect it as always, everything that is bad will be still bad, but... if i restart my phone with the accessory connected and Bluetooh still ON, before the rom loads completely the accessory reconnects again a voila! all the troubles will be gone!... pitifully, if I disconnect it again the troubles will be back.
I tried with my BT headset (MDR100ABN), and my car audio (PIONEER) and confirm with both ones this workaround success, so... maybe you wanna give a try until SONY brings a proper fix to this.

I have receive a feedback from Sony Support. They say this issue is not old and happens always after big updates. Due to the version updates on the smartphone from 6 to 7, but not on the software from the car system which is still the old android it is needed to update also the car android version. So you need to contact your car seller and ask for an update or when it is planned!
After this everything should work fine again.
I will contact on my volvo dealer on monday to check for the update.
For me it is clear. Next time I will wait first for the car update before to upgrad the smartphone!!

What phone do you have? Cuz I'm pretty sure it's not an XZ premium!
Also what Android version are you on?

Hi, perhaps my headset was new, I tried resetting it and still only works with the workaround, also my car audio still get the issue, and only works with the workaround.

Do all cars run on Android? I never knew that (and I actually doubt it...).
The point is, however, that BlueTooth functionality has been completely buggered with Android 7.0. I am listening on a BlueTooth headphone set right now and had something very odd happened just seconds ago: I already reported in another thread that the BlueTooth volume control has been messed up, the step between levels 3 and 4 is way too big. Just now, however, while playing at volume level 3 I tried to adjust the volume on my headphones, and it showed on my phone that the BlueTooth volume was at a completely different level. The volume level was suddenly much better, though, and with better spacing between the levels! However, it wouldn't go below ~50% when adjusting on my headphones, there would be some sort of error signal from my headphones. I then adjusted the volume directly on my phone and it jumped back to the normal bad volume settings, and now it stays like that also when adjusting it on my headphones. So somehow the communication between phone and headphones went haywire at first, which it never did before on Android 6.0.
