Bluetooth on Note 8.0 LTE version

Hello everyone,
I need samw help please with my bluetooth on my new Note 8.0 LTE.
When I connect a bluetooth headset sametime it will disconnected a reconnect at random times and sametime it fine it will never disconnect.
The bluetooth on my Peugeot 3008 is fine once it connect it will only disconnect when I switch of the car and leave but with my Motorola Elite Flip it will disconnected a reconnect at random time.
I try another new headset the Jabra Motion and I cannot have a fix connect keep connecting disconnecting all the time.
I use a Pebble Watch as well but that is fine it only disconnects when I shutdown the watch.
Has anybody experience this problem, and if so any fix to stop this happening?
The pda was purchased in Hong Kong it has the Hong Kong Jelly Bean version 4.1.2 on it in English. Everything else simes to work fine like charging WIFI IRDA Phone its just this problem with bluetooth.
Any help would be very greatful.
Please Help me.
Thanks
Gigino

Bluetooth is kind of buggy on the Note IMHO (I have the Wi-Fi model). Regularly I have to restart Bluetooth (toggle off than on) to get things to connect or scanning to work.

Car Bluetooth issues (Mazda)

My Pixel XL is having a hard time connecting to my car's Bluetooth (Mazda 3). I had no problem pairing, but connecting seems to be hit or miss. Once it connects, things seem to work fine. Any advice?

My advice is get used to it. Not being mean saying that, its just that Android bluetooth has been hit or miss for a long long time now. Some will work well with some devices and some will not. And it will change every once in awhile after an update.
Toss a Bluetooth toggle on your home screen

If you're not on the latest security update, I'd suggest that you install it. Older GM vehicles had an issue connecting to BlueTooth. It was resolved with the December 7.1.1 update.

Yes, I am currently on 7.1.1.

Is there an official Google PixelXL forum where I can voice my concerns so that Google/Pixel people come in contact with my grievances in a more direct manner?
Thank you!

I think I've noticed a pattern that might be relevant for this issue: After rebooting, connection happens pretty much instantly. It gets gradually slower everytime i connect afterwards, until the A2DP profile stops connecting altogether, after the 4rd or 5th connection attempt. Rebooting the Pixel resets this cycle.
Interestingly, these connection issues happen only with my Mazda car. No other BT devices have problems connecting to the PixelXL, which makes me think that this might be a Mazda issue rather than a Pixel issue. But then again, I had no such problems when connecting my Mazda to my Galaxy S6. Not sure what to think.

Mi6 bluetooth problems

Each time I use Mi6 via bluetooth in car to answer/make calls - first call goes OK, and all others not - people I talk to don't hear me. It happena in 4 different cars so it's not car's problem. Mi5 was OK. I run 7.1.1 NMF26X global beta. miui 8 7.6.8 global beta. And can't solve it myself. Tried deleting and re-adding cars, restarted phone - nothing helped. When I switch to phone during call - it's OK. As soon as I switch back to car - same problem. No one hears me and I hear everyone.

Any1?

I'm sorry but I can't test because I don't have any Bluetooth devices.

Not using any bluetooth device either.

Hello there
I'm a new xiaomi mi6 user. I have 7.5.25 version rom installed on my phone. My phone does not see andriod wear app on my smart clock with bluetooth. Also does not share internet with hotspot. There is also a problem with the GPS, the satellites can not find it immediately. can you help me.
Thank you

Ok, one by one.
1. My phone does not see andriod wear app on my smart clock with bluetooth --> My watch works, did you unpair your watch with old phone first? Android wear watch can only connect to 1 phone.
2. There's personal hotspot, you can see it in the settings menu.
3. GPS needs time to find your phone, you need to have wifi (or mobile data connection to assist the phone), if it located your phone, next time GPS will work faster.

It is a different issue with me: when paired with a BT device with the "phone audio" profile enabled, despite picking up the call on via pressing the green button on the touchscreen, it still defaults to the BT device (and I have to switch audio back to "phone" before the other person cuts off after hearing nothing). This is on the global ROM 8.2.2.0...
The global ROM seems buggy as hell...

Hello Friend.
The same happens to me.
It connects to bluetooth but I have no output or audio input.
Did you get it fixed?
Thank you

Everyone.
This is not xiaomi's problem.
This problem is due to oreo's new bluetooth stack.
There is no current solution to this. I've searched far, wide and deep.
Android has a great track record in keeping the bluetooth stack broken.
If you try to search google, you will find out that not only xiaomi phones have this problem.
The only theoretical solution is to port old bluetooth blobs, and somehow make it work. But as far as i know, no one has done this before.
There is hope that android pie will fix this. But from what i read, early builds of pie still has this problem.

Bluetooth always reconnecting in car

The problem is to connect Bluetooth on a Moto Z Play Android 7.1.1 patchlevel 2/2018 (current in reteu, was same result with Android 6.0.1 12/2016) with a Volvo XC40 car.
The first pairing with Bluetooth succeeds for a second. Then, nearly immediately, both displays (car and mobile) show reconnecting for about 10 seconds. It has a connect for a fraction of a second, and then is reconnecting and so on.
Trying flight mode and then only Bluetooth enabled on the mobile did not help. IIRC it showed some message about "My Volvo Carnull not bonded" (the name of the car for Bluetooth is "My Volvo Car" and some message with typo, something like "conecnting not successful". After that I rebooted, result was the state before with reconnecting.
Did try this several times. Also did try to reduce the amount of Bluetooth access types the car tries. There are 4 connected: phone, audio, internet, contacts. Did also not help.
Has anyone an idea how to get a successful connection or what the cause of the problem is? Did search for similar problems with Bluetooth in cars, but could not find anything (except for that hint with flight mode which did not help).

What I tried by now:
- Flight mode, only Bluetooth (as already mentioned). No change
- Remove all bluetooth connections. Pair new. No change
- Delete data for sytem app "Bluetooth Freigabe". No change
All other bluetooth connections are working fine. Another Moto Z Play using Android 7.0 (01/2017) is working flawlessly with that car. Strange for me is that it didn't work on 6.0.1 in the same way it does now fail on 7.1.1, but the other Moto Z Play using 7.0 is connecting stable.
Still the question: Does anyone have an idea how to get the connection working?

Factory reset?
I see that you deleted all bt connection but do you have some apps that are using bt? Like for smartwatch, headphones...?
I have Amazfit and watch must be connected to be able to pair a new device. Drow me crazy first time when I had that problem. I thought that car audio is broken, then phone... After pairing, watch doesn't have to be connected to reconnect.

I was afraid this reply could come. When doing a factory reset, I do following: Pack /data/media somewhere because Nandroid omits this. Backup all partitions using twrp. Backup all apk using adb. Export SMS. Export contacts. Screenshots of the launcher screens. All this takes about 2-3 hours. Then I struggle a week until my device behaves like before. I'd be willing to do it if I saw a reason why it could help.

Headphone, yes, there is August EP650 configuration tool that is not necessary. Thank you for the hint, will try it. Also I read somewhere it may help to delete cache partition, that's also worth a try before doing factory reset. Maybe I'll wait for Oreo before trying factory reset, could be they fixed some bug there.
Edit: BatOn which shows Bluetooth battery for external devices could also be the culprit.

That's a strange behavior indeed. Amazfit seems to do something wrong.

It doesn't get any better if you upgrade to Oreo, I've been having problems with my Moto Z play disconnecting and reconnecting to the radio in my Corolla constantly ever since I went up to nougat. To be honest I just bought a good pair of headphones and stopped using the radio. Good luck though, if someone finds something that helps let me know.

I'm using bt with car audio, headphones, smartwatch... No problems at all, except one with Amazfit. And that is related to their bt implementation, not Moto fault.

Seems the last action to remove Bluetooth related apps was the right one . There were two apps installed:
1. BatOn showing the state of battery of connected Bluetooth device
2. August configuration app for August EP650 headset
Removed both as they are usually not needed and it seems to work now. Will see later if it only worked for the short test I did today (currently I try to avoid driving because of an injury) or if it keeps stable.

Good, you didn't have to factory reset after all

Bluetooth, 4G connectivity and notifications issues

hi everyone,
(i posted a similar message to another thread which might be obsolete)
my previous phone was a redmi note 6 pro and now i run a redmi note 8.
On both phones are installed the same apps, same use and same connected devices.
Issues on redmi note 8 (runs MIUI Global 11.0.4 PCOMIXM Stable):
1. it cannot maintain bluetooth connection (initially is connected but connection breaks as long as a call takes place) with car's infotainment . I've read that smartwatch app might cause the problem, in my case amazfit, which is true but i do need both amazfit app and bluetooth connection to my car. I changed AVRCP from default 1.4 to 1.6 but didnt help. Any help?
2. While redmi note 8 is connected to bluetooth headset (i've checked meizu ep51 and mi sports) all text message notifications sounds go through the headset not the phone. Notifications settings are checked. I think its a wider issue. A workaround is to disable media audio for specific bluetooth connections but you can not listen music thru the headset then.
surprisingly Redmi note 6 pro handled all aforementioned successfully.
3. mobile internet connections is often interrupted (for an unknown to me reason) and i have to switch on-off airplane mode to restore internet connection

nope
in addition to all these issues i realized that from some apps with all necessary permissions given there are no notifications at all. Another issue is that DND seems not to work. No matter if DND is enabled or not by AutoDND option, sounds are active unless i turn on or off manually
I wonder if a custom ROM is free of these bugs, but which one?

why don't you try flashing the stock ROM with mi flash via the fastboot method and then see if these issues still exist.

In case the ROM hasn't been flashed correctly?
Does it make difference from downloading the latest package by the updater menu?

Yes you can update from updater app too...but it's much better if you flash via mi flash fastboot method as it's a much more clean flashing and also it flashes all the partitions... fastboot flash is known to solve some issues...make sure you have a backup of your data .... you'll also need an unlocked bootloader but that's not an issue as you can lock your bootloader again if you want to while flashing via mi flash

No , i have no solution of anything. I reflashed phone's same ROM, no hope.
I look for a custom rom hoping it would be bug free

Same problem here ( Redmi Note 8T MIUI V11.0.3.0.PCXEUXM)... Using Notify & Fitness for Amazfit with my Amazfit GTR and connection is unstable, every now and then connection is lost. Also transferring watchface is taking long time, about 10 seconds for 1%, and on my old Huawei it is about 1 second for 1%. I also tried another watch, but same problems. Tried every AVRCP setting (1.3, 1.4, 1.5 and 1.6) but same issues. Has anyone tried custom ROM or maybe MIUI EU? I'll try but have to wait 1 week for unlocking bootloader.

I also have to wait one week to unlock my phone. Firstly I'll try a XTRV ROM which is China source based.
