Why is Bluetooth so screwey on Pixel 2 XL?

[CPngN]

I thought Pie would fix this, but it's roughly the same BS, only now each device gets its own volume.. eventually.
I regularly have trouble getting BT to see a device and connect to it. It seems 10 seconds is about the fastest it will connect in a way that I can play media out of some earbuds or shower speaker.. sometimes it never completes the connection. Pretty much EVERY time, it does this strange thing where it connects with BT phone quickly, then Android jacks the volume up to 100%, THEN connects to BT media. If I'm playing something while that happens, it suddenly BLASTS OUT OF MY PHONE SPEAKERS FOR A split second or two, then comes out of my BT device.

WTF is this all about? Is anyone else seeing this? I actually see the volume slider popup, go to MAX volume, then drop back down if and when it connects media to the BT device. I don't have any "Bluetooth manager apps" installed, though it's tempting but i doubt they would fix this an likely make it twice as crazy.

Google store Pixel 2 XL 128 here on Pie, but this was also happening in Oreo.

Yea, BT on Android is a mess. Has been since 8.0 came out. They fix it with an update for some people and that update breaks it for other people. I am about done with it.

It's not much but you could use tasker plus an app like (or even as) "volume profile for tasker" ( https://play.google.com/store/apps/details?id=jp.meridiani.apps.volumeprofile )

I honestly don't have issues with any of my Bluetooth speakers or cars. Connects just fine and remembers the volume per device just as advertised.

Same here. Bluetooth connects to my car instantly, same for my headphones.

Mine is working fine with all my devices (car, speakers, headphones).
Pie stock, no hacks.

Same here. No issues what so ever. It connects to my car, home speakers, watch and two different sets of headphones.

Mine works a treat, Much Better than Oreo...

Mine will connect with cars, but if you take a call, it drops Bluetooth music playback. The phone stays connected but no audio.

I then have to cycle Bluetooth off and on so it reconnects or reboot the radio.

It's not consistent either. Sometimes it resumes after a call and sometimes it won't. Completely random.

Also, won't connect to my car if already connected to any other device like a headphone. No way to make it favor one over the other.

Android auto has the same issues. Sometimes it works and sometimes it won't at all.

My Bluetooth connects fine, eventually, to a dozen devices. My issue wasn't with BT working or not. It's with the volume jumping up before connecting. I guess I will have to record it happening with audio so you can see how bad it is if something is playing at 50 percent vol and it jumps to full blast before switching ovrer (at which point it readjusts to the devices precious volume).

4 different BT headphones and a cheap chinese car stereo. All work perfect on Pie with individual volumes. My personal opinion is BT is much improved in Pie.

My P2XL gets ahead of itself. I just tried something: started music in my media app (GONEmad Music Player), turned on BT, on my Mac I opened BT preferences, on phone I tapped Pair New Device, and on Mac tapped on Pixel 2 XL when it showed up. Before I even entered the PIN displayed on the screen, the volume jumped up to 100%. On the phone. While playing music at 15%. I denied the pairing, but something maxed out my volume as soon as BT started ATTEMPTING to pair..... wtf!?

I'm able to re-attempt the connection, and get a new PIN presented, along with MAXED out volume each time I do that. Even without music playing the volume slider appears on the screen. I can stay in BT settings and attempt to repair to the same device, and each time (before the PIN even pops up for me to verify), the media volume maxes out, even if I jump in and change it before it disappears (meaning there's no pseudo-device which it is remembering volume for).

Here's a video of the volume jumping prior to connection (or in this case even prior to pairing happens)

The only thing is noticed is that you're connecting connecting to computers when this happens. Just tried my headphones and no such jump I'm volume.

Computers, BT shower speakers, 1 year old BT4.1 Anker ear buds, doesn't matter, same thing happens.

I just unpaired my Anker SoundBuds Curve, had music playing low, re-paired the buds, and no volume fluctuations. Can't replicate it on my end.

It works perfectly for me after the September update. Now I can call over Bluetooth again. The previous updates somehow messed the routing of incoming/outgoing calls for me. All good now. Hopefully the next security update doesn't break anything.

Ugh, thx for checking. It's like I have a service watching for Bluetooth activity and trying to outthink the OS. I disabled Tasker but same result.

i've been having some bluetooth weirdness as well. my huawei watch works fine, until i jump in my truck and my phone connects to the bluetooth in my head unit. Then it takes forever to get my watch to resync with my phone. I've reset my watch and reconnected it twice but it still seems to do the exact same thing.

Hmm ok... so I have my volume turned down on my ear buds today. Well, up on the buds, but down on the phone (disabled that BT fullblast option in Developer Options). Now I see that it's setting the volume not necessarily to MAX volume, but to the volume saved for that BT device, but it does it early... before the point where the media being played is rerouted by a few seconds. If you DO have your BT device going full-volume, then you get this few seconds of NICE LOUD MUSIC/SHOW out of the phone before switching actually routing audio to the device. It's worse if I have both Media and phone going to the BT device, as it connects the phone stream first, and thus adjusts volume immediately, then connects and routes Media a few seconds later.
I guess I just need to get in the habbit of pausing whatever I'm listening to when I switch...
