Bluetooth disconnection during calls - new Mazda 3 - Samsung Galaxy Note 20 Ultra Questions & Answers

Hello everyone!
I noticed that during conversations with the car speakerphone, the bluetooth disconnects sporadically, forcing me to use the phone with my hands.
Same problem also found when connecting the phone to the car via cable to use Android Auto.
Any solution other than "Amazon returns"?

Try disabling all power management for starters.

No issues with the new CX-5 radio... As mentioned - check the power management. Theoretically, it could be some RF jamming / noise caused by your appliances or outdoor devices - have you noticed the places where the disconnects had happened?

SW2 + Galaxy S4 + car handsfree + bluethooth = problem

Hi all
I have a problem in my Chrysler Yoyager (town & country). When my smartwatch 2 is connected to my S4 I get disturbance when trying to talk over the cars handsfree. When I turn off the smartwatch the sound becomes normal again. No I am a little bit confused. Is this a problem with bluethooth in the phone, in the car or in the SW. So far I have not figure out what the cause is.
I dont like to turn off the SW in the car. Then I have to look at the phone while I am driving. My wife dont like that.

This problem has been reported in the past also from other users:

As it generally doesn't occur with BT headsets or other car kits, I suspect that it's related to some protocol incompatibility between the BT stacks.
On the S4 try disabling all unwanted and unused BT profiles between your devices within the BT pairing settings menu.
OK, thanks I missed that. I was able to improve the sound following the discussion in the other thread.

Bluetooth in not a "collision avoidance" protocol like Ethernet. Therefore this interference is quite common between close Bluetooth devices.

Issues connecting to bluetooth devices yet my android watch seems to not have issue

I have a Huawei Watch and it seems to keep connection with my S6 just fine. I however have issues with every other bluetooth device at times. I have a shower speaker/phone, car 1 bluetooth phone + audio, Car 2 bluetooth phone only, and car 2 bluetooth music gateway. All of these have issues.
I can't get the S6 to connect some times so I have to turn bluetooth off then back on. Sometimes that works, but sometimes I have to restart the whole phone for it to work. Does anyone else have similar bluetooth issues? It is driving me nuts.

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 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.

Question Bluetooth in my car only switches on for calls not audio

I upgraded to s22 ultra from s21. When I get into my car my Bluetooth pairs with my phone for CALLS automatically, however not for AUDIO (both connect on its own once in a while) . I have to manually go into Bluetooth settings and switch on manually. This is annoying since I have a job where I'm in and out of my car. This was never an issue with my previous phone (S21)
Things I have tried but no luck.
In Bluetooth app settings clear data.
In Bluetooth app setting unpair and delete every device in memory.
In Bluetooth agent setting - change battery saving mode to unrestricted from optimized
Hmmm that seems strange.. Maybe try making sure auto is checked in the bluetooth seetings. I have the same phone and I'm not experiencing audio issues.
maybe try running a routine for the bluetooth
There is definitely something wrong with BT in the latest firmware. I occasionally get volume drops and those are huge drops. This bug happened in one or two previous firmware too, got sorted out, but in the latest there is it again. I hope it will be fixed ASAP.
Is it a Ford ?
You have to manually select the phone in Source to play audio or anything else.
Calls take priority over any setting, so they work always without an issue.

It's an aftermarket Bluetooth added to an old Honda via peripheral plugged into the stock cd player unit. I am going to try and disconnecting the battery terminals for 30 mins so I can reset the Bluetooth unit itself.
When I have my car bluetooth device connected as "audio" only, then I have to manually connect to it from my phone.
When I have my car bluetooth device connected as "audio & calls" , then the s22 ultra connects automatically
I recall reading that audio+calls connects automatically
Audio only requires manual connection
I drive a 2017 Ford F150 but I think its not a Ford issue
