Bluetooth issues after update - Moto Z4 Questions & Answers

On June 2nd 2020 I received software update
QDFS30.130-42-1-2
Immediately after restarting my Z4, sound was intermittent when connected to a Bluetooth speaker and now sometimes it just drops out altogether.
The issue seems to stop when I disconnect from Wi-Fi and mobile networks, as was suggested by Motorola support, but I kind of need those.
Anybody else having this issue?

Bluetooth unreliable?

I'm not sure when this issue started exactly but I've noticed that when using bluetooth both at home (I have a set of cordless phones with bluetooth link) and when linked to my two automobiles both receiving and initiating calls after a few seconds of conversation the phone suddenly switches to using the microphone and earphone instead of the bluetooth connection. This has occured with wifi on and off...in 3g and 2g areas....while tethering and not....etc....seems to be consistant with the device and I don't recall it doing it in the past so I'm wondering if the most recent 6045i update to ue40 might be part of the problem....in any case I'm looking for suggestions of apps or settings changes that might help with the bluetooth. I should mention I've also had music playing in the car drop at random intervals or at least I stop being able to hear it. This was playing local content so it wasn't a streaming issue.

Bluetooth crashing car stereo since update

I have a 2014 Toyota tundra. Before the update my Bluetooth was working perfect. Since the update, anytime I turn on the Bluetooth, it reboots/crashes my stereo. Just wondering if anyone else has had this same problem?

I have a Toyota Avalon and I am also having bluetooth issues since the 6.0.1 update. I have to power down the stereo and bluetooth on the phone to get the Media audio portion of bluetooth to connect. The Call audio connects fine automatically.
I called Verizon and they have has some reports of issues with this. They documented the issue and transferred me Samsung with no resolution.
Marshmallow on all the Nexus devices appear to have issues with Bluetooth according to these sites, could the issue be a marshmallow wide issue?

I just wanted to chime in. I have a 2004 Corolla and I don't have native Bluetooth audio connectivity so I use: FlexSMART X3 Bluetooth FM Transmitter. So far so good since the update to Marshallow and use with my LG HBS 750 Bluetooth Headset is ok as well. Sorry, sort of not really the same issue, but its working ok since Monday, when I took the OTA update to Marshmallow. Hopefully they Verizon/Samsung has a fix for this issue.
Same issue
I have a 2015 Highlander and have exact same issue. If you go to settings and then bluetooth, click the sprocket next to the paired toyota device and turn off contact and call sync, it will stop crashing your Toyota stereo. It does mean that your contacts and call history will not show in your Toyota system. I reinstalled android 5.1.1 from www sammobile.com/firmwares/database/SMN920V/ download 5.1.1 and follow the instructions at the bottom of the page. The download takes about 2 hours but worth having my toyota stereo working again. I have contacted Toyota and Verizon and both have been zero help. :crying:

Bluetooth issues

I read through all the threads and did not see this one. I can't connect to the Android head unit in my truck with the Pixel. It worked fine with the 5x on Nougat 7.0 but not the Pixel. I have reset them both to no avail. I read today that it is a known issue with 7.1 that Google is addressing "Google's new phone is having trouble pairing or staying connected to Bluetooth in many cars" but worried since I did not see it on here maybe its my phone. Plus my head unit is essentially an Android tablet in the dash. Has anyone else experienced this?
I have mine connected to my 2006 Charger Uconnect without any problems. It sounds wonderful and does not disconnect. I have also connected it with several wireless speaker without any issues.
Sometimes rebooting the phone temporarily fixes bluetooth connections issues.
Has any experienced no ring-back tones when doing an outgoing call when connected to a Bluetooth headset device but making the call from the phone? It only stated occurring(I think) with the November release. I am on Verizon.
It appears the phone does switch to handset speaker until the call is connected. Very annoying for me as I use an in house Bluetooth device that connects to my in house phone.
There are known issues with Bluetooth connections and vehicles. See this thread from the product forums:

bluetooth oreo issues

I thought I read somewhere that people were having issues but I couldn't find the thread.
Issue is that after update, the Bluetooth in my car won't sinc over the artist and title anymore. It plays fine, I just have no clue what song is playing. Haven't had a call yet, so can't vouch for that as well.
Anyone experiencing issues with Bluetooth on Oreo?
I believe it a Google problem have the problem on 6p 8.1.
Mi Band 2 worked flawlessly with Nougat and suddenly after the Oreo-update, I have to reconnect it a few times in a week manually or it won't send any data to my phone.
It works great in my car
Just switched to Oreo and now my Garmin watch will not stay connected. Drops in an out or just does not connect at all
Wifi & Bluetooth not turning ON
Hello, Im having problem with my mate 9 MHA-L29C636B191 it somehow disabled wifi and bluetooth,
I thought at first it was just the update to B191. Last night i got the Oreo update using Data and succeed upgrading but still my Wifi and Bluetooth is not turning ON. Should I go to a service center and request for a replacement Wifi &
Bluetooth parts? Any thoughts? Hoping someone can give any advice.Thanks in advance

Bluetooth issue in car: Stock ROM vs non-stock ROM

Hi all,
I have a 2008 vehicle in which Bluetooth seems to be a problem depending on which ROM I have installed on the device.
I'm currently on Android 9 OB 7 and Bluetooth connects and stays connected through incoming and outgoing calls. Works flawlessly.
However, with for example Lineage (among others), the Bluetooth pairs, but connection drops soon after or drops after the first call with the car stereo showing "Net Search", meaning the car BT lost service but the phone Bluetooth is still connected. I've tried restarting and resetting network settings but no luck at all. Changing dev options doesn't work either.
I'm thinking it could be a Bluetooth stack difference?
Is there a way to replace the lineage Bluetooth with OOS?
There is no bluetooth.default.so file that I could find
Any help or direction is appreciated.

I am having the same issue with 9.0.2 OOS. So not sure if this us a compatibility issue with more than 1-2 years old vehicles or something else? Glad to hear that OB7 is working fine for you. Hope fix is coming soon. It's simply annoying.
I am having car connection issues as well. I have a 2010 Ford Edge. Just moved from Sony Xperia XA1 Ultra on Orea to my first OP device - OP6 Pie 9.0.2 - I can connect to my car initially but once I turn off my car, I have to go through a series of reconnect steps. I called tech support and we spent about 45 min troubleshooting - of course I was told I was the only one who had complained of this issue - anyway no resolution. The only way I can "reconnect" is to go into my car's system settings and select "connect to BT device" then toggle bluetooth off and on in the phone - sometimes this works with the first go, other times I have to repeat this cycle 5 or 6 times. Simply selecting "previously paired devices" in the phone app doesn't work either.
Really a pain in the tush, because I am usually in a hurry and don't have time to go through all this scenario to get a connection.
On the other hand, I have a bluetooth ear piece (made by Samsung that is like 5 or 6 years old) that reconnects every time I turn it on, no problems.
Car connections too but was not present in omni
I found for stock, performing a network reset (mobile, wifi Bluetooth) then restarting the device fixed the Bluetooth connection issue.
For custom non-stock ROMs, for my issue at least, I found its not a Bluetooth issue at all but rather the mobile network drops and the car Bluetooth cannot reconnect. The same network reset as above does not work but what does work is toggle off the "automatically select network" and manually select the mobile network from the menu that pops up. This keeps the mobile network intact (until the next device reboot, at which point repeat the steps) with the car and all is good.
I only figured it out by accident; hope this helps others.
