Miui 11.0.1.0 (QFGE EXM) update, bluetooth devices not always connected - Xiaomi Redmi Note 7 Pro Questions & Answers

In August I got the Miui 11.0.1.0 (QFGE EXM) with the july security patch updates on my global versions note 7. Since then my bluetooth headsets (plantronics voyager legend) constantly have problems with the audio. Basically, the headset is connected but sound is not played. Sometimes the loudspaeker on phon eplays sound, sometimes the sound is playing nowhere. Switching off on of the headset sometimes helps, often not. The only thing that helps always is restarting the phone.
Anyone else has the same problem?. What could be the cause? I understood 11.0.4 is already circulating but wasn't offered yet to my phone. Does anyone have a problem on those phones?

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 no call audio pixel

I used to be able to hear calls and media whilst connected to bluetooth in my car. one day it just stopped working. media still works but when i make a call or receive one, there's no audio. calls ,audio, and contacts are all checked in bluetooth settings. i've forgotten devices, rebooted, reconnecting, and nothing helps.
bluetooth connects to everything fine, but no call sound over any accessory i try. got a new car and it won't work in there either. i'm on android 7.1.2 .
searched all over and plenty of people are having these issues but none of the posts i've read solve my problem. any help would be appreciated
Hey hey, I have a 128GB pixel with the same issue. I actually opened a case with Google support today about it. about 3 months back, only phone audio stopped working in my car. I was hoping the 8.0 update would fix it but it did not. I have a 2017 Honda Civic LX. I tried everything on my phone - even factory reset. Media audio works, I can play Spotify just fine but when i get a call, I can not hear the other person and they cannot hear me. The phone indicates it is connected via bluethooth... I'll try to update this post with what they find.

128G pixel here. This happens with every Bluetooth device I connect it to. 2 car stereos, 2 speakers, and a headset. All worked fine and suddenly one day... Didn't. I was hoping O Would fix it with all the Bluetooth bug fixes and changes they implemented.

Darn, so the issue is a bit different. Mine works fine on a couple of other speakers I have.
Did anyone ever solve this? I've got the same issue, but it effects *all* my Bluetooth devices, but only when I am switched to my secondary user profile.
I've reset the phone app but no dice.
My phone will say it is connected to the Bluetooth device for the phone call. If I switch to speaker or phone and then back to Bluetooth, it works. Anyone else have similar?

Hi!
After hours of Googling you are the first I found who has the same error.
I have a Lenovo TAB4 8+, my kid wants to use Zoom and his Bluetooth headset but only the speaker and mic on the tablet works. I tried fresh install, without luck:
There are 4 type of users:
- Owner (primary - this is the only profile which works for calls on bluetooth headset)
- Standard Users (secondary - bt headset only supports listening: Spotify etc..)
- Child (bt headset only supports listening: Spotify etc..)
- Guest
The bluetooth headset is working with other devices, but not with this one. Unfortunately I have no other android device which supports multi-user.
Moreover, there was an hour when bt call worked from secondary user, but couldn't find out what is the problem.
Can anybody help me on this?
Best regards,
Karoly

Bluetooth issues on Oreo 8.0 & 8.1 update

Hi,
Since the Oreo initial update (8.0), when playing Youtube musics in my car, the title of the videos are not synced with the radio screen (a VW Passat). The first video played, the title is correct but from that point it basically stops updating or shows a previous played video title and not the correct one being played. On Nougat it worked perfectly...
So, I heard that Oreo 8.0 had some Bluetooth issues that Google addressed in Oreo 8.1. (you can imagine my question, right? ). When will Huawei release the update to our Mate 9?
BTW, anyone having Bluetooth issues with Oreo 8.0 that would like to share here?
Txs.
I've been having BT issues since the Oreo 8.0 update as well. For me, I use a BT to FM modulator for my car. Used to connect to it with zero issues before update. Now since, sometimes it won't even connect unless unpair and re-pair the device. This does not happen with any of my other BT devices oddly.

In Developer Options I noticed there were options to change Bluetooth codec and bitrate. I have no idea if this will help, but it might be worth a try.
I get a crackling sound (BT headset), but sometimes also when I'm connected to the car in phone calls only, both ends of the conversation. I think my issue is more with an overloaded system at "quitting time". AT&T doesn't have enough towers in my area.
Had a BT issue with our car today (2014 Kia Rio). It failed to pick up when I told it to connect. ( Phone said connected but car didn't follow suit).Deleting the pair from the phone and the car plus a reboot fixed the issue for me. Sitting on B366 with stock everything.
My experience has been the opposite, running 8.0.0.366 (C432) with no BT issues. No issues now, no issues before under Nougat.
That includes connecting/streaming to cheap whiteline BT speakers, Sony BT speaker, Bosch and Clarion car radios, LG TV Soundbar, Xiaomi BT car lighter adapter, Gear S3 Frontier, Xiaomi Mi Band 2, sending files to a P20, sending files to a 2014 MacBook Air, etc.
All flawless, no disconnections even after extended periods of time (1h30 streaming continuously), no drop in sound quality, same long range.

Android Pie handsfree problem

I have this problem with the Android Pie version on both MIUI versions. After a few minutes the cell phone is disconnected from the handsfree car radio. Bluetooth media continues to work and voice call also works, but it does not connect to the car radio in handsfree mode although I can speak through it. Sometimes I can't even connect with it but only the phone mode. I've tried everyting, clean install and wipe everything on the car radio, but no luck. It works perfect on the Oreo version of 10.0.2.0 but all the Pie versions have this problem. From what I found it looks like there is some problem on Android Pie about the handsfree bluetooth issue, but most of the people report that after the Security Patch update of October, all the issues are gone, but for me the issue remains. My car radio is based on R-link 2 from renault, which is based on Android. Does anyone knows how to handle this? Thanks.

Question BT audio trouble?

Anyone else finding that the Bluetooth audio can be a bit hit and miss, the audio has just fully cut out on me, but it displays as if it's still connected and playing via the headphones. I had no audio through either headphones, switching BT off and on, and rebooting headsets didn't solve it. Rebooting the phone brought the audio back, phew!
Out of the two headsets I have, My cheap Sony WI-C310's seem to work better, Using my jabra halo smart headset, it doesn't seem to connect media audio if it's also allowed to handle calls. I have to toggle calls off and just media to use Spotify with the headset (this could just be that headset being weird, think it got discontinued for not being great)
Anyone else having BT audio issues?
I've got a Huawei smart band 6 connected at the same time if that's a factor, it wasn't a problem on my original Nord though.
I have been facing the same issue for a while now, it's pretty random. There are times where it works perfectly and other times it either doesn't connect at all, or has a very weird delay, where it's fine in the beginning of say a video and gets a delay mid way through it. There are times where it only connects to one earphone, just issues all around. Also am using the oneplus buds z2, so honestly would expect it to work flawlessly with a oneplus device. The earphones work fine with other devices.
I've been getting random drop outs.
Both with connectivity with my car infotainment system and my cycle computer.
When I had my OP7Pro, never experienced anything of the sort when connected to these two same devices.
I've also tried enabling Bluetooth Gabeldorsche in the developer settings, and that didn't make a difference.
Will try changing the Bluetooth AVRCP version to see if that improves anything (currently set to the default of 1.5).
Has anyone else played with those settings and tested the impact?
Tested with 3-4 Bluetooth devices and no drop outs.
I notice that when I put the device in aereo mode the Bluetooth remain active, but in the latest days this problem doesn't happen anymore, maybe was a bug of the first fw, and after last update they have fixed?
