Nougat Bluetooth bugs - A7 2017 - Samsung Galaxy A3, A5, A7 (2017) Questions & Answe

I found a nasty bug with the recent Nougat update for the A7 2017 (SM-A720F): some Bluetooth devices can't pair with the phone anymore. In my case, it was a Polar H10 HRM (BLE); other devices like my car and watch pair just fine. Researching on the topic a bit, it seems it's not something exclusive to Samsung phones: the Android 7.0 version is plagued with Bluetooth issues, which apparently have been solved in version 7.1.1 onwards.
I've tried about every solution and workaround I found: clear cache in recovery; clear Bluetooth data; perform a master reset; and even reflashed the stock Nougat ROM in Odin from scratch. I also tried pairing the HRM with several fitness apps, including Samsung Health. The ONLY thing that worked was downgrading to the stock MM ROM (6.0.1): pairing was instant.
Anybody else had Bluetooth issues with this Nougat update? Any other workarounds I could try? I just hope Samsung is aware of the issue, and release a fix soon.

Yes my Garmin 935 won't pair, tried to downgrade with odin but it failed so I'll try again tomorrow. Phone is frigging useless if I can't use it in conjunction with my watch.

yes me to..with jbl clip2 n level u music sound broken off

Hello,

Thanks

[Q] XXUFNG4 and problems with Bluetooth

Hi, I found this thing, I tried now lately 2 ROM (Dr.Ketan v9 and X-TREME v4) based on the official firmware XXUFNG4 and both showed me the problem with disconnecting Sony SmartWatch SW2.
I do not know if it's any systemic "property" or somehow reduce the scope for bluetooth? I wear a watch on his left hand and a phone in my case right on the belt.
Restart (both phone and watch) did not help.
He did not meet anyone with the same problem? (N7100)
So I think I found the solution to my problem.
It is not perfect, but I watch it does not disconnect.
If you set the visible BT, respectively. time limit visibility to none, so the watch will stop disconnecting. Except that the patch phone's visibility is greater consumption.
I tried to Blutooth range fix from Dr. Ketan on X-TREAME ROM problem with bluetooth and it worked, but again there were problems other.
See. click here.
Can't fix the BT problem after flash NG4 based roms (tryied Ketan v10 and Phanton v9). When try to connect to my Gear1, the ConnectionManager as stopped.
Even flashing the BT range fix doesn't work for me.
Clean install without restore anything of sammyaccount, doesen't work too

Bluetooth issues

Hi. Wondering if anybody could help. When I connect my oneplus 5T to my car I have problems. When it starts to call it disconnects the bluetooth from the car completely. However the call continues on the phone which is a complete pain as you cant use it through the hands free. Car is a BMW 630CI with pro nav if that helps.
Many Thanks
i first had problems to connect to my audi A3 bluetooth ... it simply didn´t find it
after trying again and changing the bluetooth audio codec it suddenly worked ...
Idk if it will work for you, but you can try changing the codec and se if it helps
Hi. Ive tried all 3. It connects fine and I can see my contacts but as soon as I hit dial it disconnects from the car.
Very strange.
Thanks for the suggestion tho
with mine in my car it every now and then gives me this a crackling sound.. Kind of irritating, I'm hoping a software update down the road fixes this.. I've tried all 3 codecs
Having issues with Bluetooth connection on my Prius Prime as well. It always disconnects, I had to disable Bluetooth on the phone and re-able it for it to work.
I experience the same with my Boss QC35. First connection, audio breaks with lots of noise and had to disable it and re-enable it.
Still found no solution. Hope the next update sorts it out as the bluetooth seems a mess.
So after looking around, there are issues with certain codecs and devices connecting being posted in the OP community forums. My Sony WH1000xm2 headphones stutter when using AptX HD. My JBL Everest 750NC's - if you turn the volume up too high, they disconnect from the phone. In my Cadillac ATS, whenever you place a call it'll stay connected, but you won't hear anything, and the other user can't hear you either.
I think they've acknowledged the issues and are working on them, but after putting Oreo on my Moto G5 Plus and Oreo's ability to change between all codec's on the fly (including native LDAC support!) I'm anxiously awaiting Oreo to be 'officially' released.
I'd say just be patient.. I'm sticking with this phone because I think it'll be worth it in the end. Wish I had better news!
so I resolved my Bluetooth issues by flashing FreedomOS. Now there is no intermittent crackling sound now and there is no issues at all ymmv, this was just my experience.
Thanks. Will wait for Oreo and then try different roms if it continues.
on FreedomOS before, it was giving me headache re-connecting to my Subaru car bluetooth, like after you shutoff engine, go somewhere and come back, unless you manually force connecting to the car, it barely auto reconnect back.
And also takes so long to get data sync from my Fitbit chargeHR to the app.
I don't think this kind of bluetooth issue related to what rom we have but the kernel and more specifically BT firmware.
-----edit-------
My friend also got BT issue when he tried to connect to BT headset. Hope Oneplus get something fixed on new oreo or updates
Just an update. Since upgrading to the official Oreo rom my problems have disappeared and my phone now works fine with the car Bluetooth.

I still have problems. Pause and unpause, and the track restarts. After ending a phone call the track restarts. 2018 RAM, Uconnect
With stock ROM 4.7.2 bluetooth connected only for a few seconds with my Audi A6. With every following stock ROM version it didn't even connect.
I tried every single Audio-Codec and the different settings in developer options - nothing helped. Once I cleared data & cache from the bluetooth system apps followed with a soft brick
Hi all,
Had same issues with my Hyundai ix35 and oneplus 5t (Nougat), tracks skipping, distorted audio in calls, etc... Tried emptying bluetooth cache, switching audio codecs without success. Now I just received the OTA update to Oreo (8.0), Oxygen rom 5.0.3 and it solved the issues!!! Yeay, no more auxilary cable hanging around !

I started from scratch but the issue persists.
I am having the same issue in my car. It no longer displays track information and the connection is not very stable. I will try switching the codec and report back.
i don.t have any volume control from the phone basically when i connect it to my car stereo
i can control the volume for the first 4-5 clicks ... and then the slider moves but there is no difference in the volume
i have to turn the volume from the stereo almost to the max
whit my old samsung tablet works great ... i have maybe 50% more volume then with my phone
tried all codecs ...

Bluetooth headset issue - no voice

Hi all,
Hope you can help me..
I've been having issues with BT headset(s) since my Honor 7x was upgraded to Oreo BND-L21 8.0.0.330(C432).
The behavior is the following..
I pair the BT headset with 7X and everything goes smoothly. When i check info section on the paired device i see that both, phone and media audio are enabled. If i play the music - everything is OK.
The issue starts when I trigger a call via 3rd party app like Whatsapp, Viber, Hangouts etc..
What happens is that the other person can hear me but I can hear them. It seems like the communication is going only one way.
If in the middle of the call i switch to phone microphone (inside app) - everything goes back to normal.
I tried with two different BT headsets and behavior is the same (both headsets work properly on another phone).One other thing to mention is that all these apps also work properly with a wired headset.
So far i tried to disable Volte, disable Wifi and perform calls via mobile network, wipe cache partition, clear data/cache for BT app, enable/disable google assistant, change permission, unpaired all devices.. But so far nothing worked...
The only thing that is left is to perform a hard reset but I would really leave this as a last resort.
Has anyone had this issue ?
Thanks!!
Having the same issue with my anker soundbuds flow headset.

Don´t bother with the hard reset, it won´t help.
In fact i´ve even replaced the phone, and on the new phone the story was the same: After the upgrade to 8.0, when a phonecall is made via App (Skype or Whatsapp) there is no sound in the BLuetooth headset, while microphone works perfectly. However is a normal phonecall is made, the headset works two ways.
The problem is reproducible on my several headsets (LG HBS-730 that uses BT 3.0 and Anker SoundBuds Life that use 4.1). The anker soundbuds flow, that were mentioned above, are also BT v4.1. Nevertheless, if i connect my Anker Soundcore 2 speaker (that uses BT v4.2) the two way communication works perfectly. Also it works on my EasyAcc speaker BT075 (BT v4.0) and Taotronics TT-BH12 headset (also BTv4.0).
So I´d assume that the update was tested only on 4.0 and 4.2 BT devices, but not on older or 4.1
So as for the solutions, i hope this problem will be addressed in the next update (hopefully soon) or consider trying the headset with BT 4.2 or later.
Update: It also does not work on speaker Aukey SK-M8 (which also reports to have BTv4.0) - strange. Maybe it is not really 4.0 or my theory with BT versions is wrong.
Thanks a lot for your feedback.
In the meantime i did some more testing with both bluetooth headsets and managed to get one working.
The headset i managed to "fix" is Plantronics voyager legend.
What i did was: downloaded "plantronics hub" app and in the settings I disabled "HD sound". By doing that everything started working correctly.
The only downside is the sound quality - it is so bad that I just decided to use a wired headset.
Hopefully this will be fixed in the next update :crying:

Those are Bluetooth v3.0 headset. Obviously the problem is with the applied profiles.
I think it would be nice to report this problem to Huawei/Honor. I really don't know whether they check this forum, more reports they get - more chances of a fix.

This morning I received an update to 331 - BND-L21 8.0.0.331 (C432).
I retested all of my BT headsets (including moving Plantronics back to "HD audio") and - everything works like a charm !!!
In the release doc it states that this update contains only a July 2018 google security patch but i guess they also fixed the BT issue.
Anyhow, I am happy again !
Cheers!

Bluetooth problem after update to 8.0

So, somewhere in May I received the automatic update to Oreo 8.0. Hurray! Sadly though, that's when my bluetooth problems started:
It connects to my car, as normal. And I can make and receive calls, as always. But during the call my bluetooth connection with my car would just drop. If the person on the other end of the line is patient enough, I can just reconnect while driving and continue. But it will drop once each minute. It's very frustrating. This worked flawlessly before the update.
Funny thing is there are no issues at all when playing music of a portable speaker. I can even play spotify through my car's speakers without problems. The problem only presents itself during calls on the carkit. To make sure it's not the car, I tried some other phones. My wife's samsung, also with 8.0, worked perfectly. So does my daughters Iphone with IOS. My car is a Volvo C30 from 2012. It has built-in phone connectivity.
What I tried:
- Unpairing and pairing again.
- Hard reset. In combination with re-pairing.
- Using the developer options to use Bluetooth AVRCP 1.4. In combination with unpairing and re-pairing.
- Using the developer options to use Bluetooth AVRCP 1.5. In combination with unpairing and re-pairing.
- Disabling automatic bluetooth/wifi scanning in the location settings.
- It even went to the repair center for a different issue (unresponsive touch-screen) and the repair notes stated that they also installed the newest software. So I had hopes that this would resolve my carkit issue, but it didn't.
Do you guys know any more tricks for me to try?

			
				
I have an XA1 ultra with Oreo 8 as well (build 48.1.A.2.21) and I'm experiencing the same problems, but adding that mine disconnects also when streaming music. Other problem I'm experiencing after the Oreo update is that,when using my watch (LG G Watch R) paired with the phone, the sound streaming is just crap, with lots of jumps and bad audio quality. This is so frustrating that I'm seriously considering buying a new phone ( not from Sony, of course)
:crying:
Anyone?

Question Audio not routing to Bluetooth earbuds

Anyone having issues with audio not routing to Bluetooth earbuds? Only fix for me so far is to reboot the phone. But the issues comes back later or the next day.
It's strange too, I'll have issue with the galaxy buds pro not working for audio or phone calls but I switch to the Sony XM4 and it works for audio but not for calls. Reboot and both works again. I've tried unpairing and resetting Bluetooth and also the earbuds but nothing works except reboot of phone.
Network reset and try clearing the system cache.
Try swiping down once then hit media output and selecting the Bluetooth device there
not sure if these will help as well but these were the solutions i have done when i had bt issues. these are not in order by the way, but alternative solutions
1) clear the bt cache. unpair then pair again
2) i installed bluetooth audio widget
3) i once bought a jam loud buds from jb hi fi. it would drop out or it wouldn't connect at all to my fold. turns out it was still paired to my old samsung note 9. had to delete that pairing and it finally worked with the fold. didn't know some devices only paired with a phone once
4) bt version. i had an old bt remote used by my daughter. it paired with the fold but did not work. did some reading and the bt version of the remote could be the cause
5) above posts from blackhawk and sonin66

Buds+ software and firmware* have given me a lot of trouble. A real pain. I'm running two N10+ N975U/N975U1's one on Pie the latter on 10.
These are the apps I load but they may not work on 11 or higher, don't know... In any case uninstalling then reinstalling may fix your issue if the network reset fails too. Firewall block "Apps (UID)10343" and Wearables Installation Manager. Keep them blocked or they will update... and you'll be repeating the process.
For all these apps they must have all their permissions enabled to open!!!
*if you have a pair of Buds+ do not upgrade their firmware! It trashed the sound in my one pair. Now they need reflashed...

done this, and the correct device was selected but no audio. Sometimes music audio works fine but not calls
Idk if this happens for you guys but I went to a sony showroom today and when I paired my mobiles with some soundbar units like sony HT-S40R, HT-G700 and HT-S500F and some other models soundbar all of them got this weird issue, we can hear the music but every 2 or 3 sec it feels like it stops and then resume ( on the music player app it's working normally) I though maybe because of my spotify app I tried Youtube, youtube music amd amp all of them gives the same weird results ... This was before rooting my phone ... Ofc after rooting it it's stil the same issue (Android 12 and 13) hopefully this happened with those specefics models and not with my earphones or headphones bluetooth
Also note my S21 ultra works perfectly with the models said above
