[Q] Bluetooth incapable of scanning devices - Galaxy S6 Q&A, Help & Troubleshooting

Hey there!
I've got a huge issue with the bluetooth on my S6. It actually doesn't seem able to recognize any bluetooth devices in its surrounding (ex: my car or my bluetooth JBL speaker). I have tried the clear the cache, to restart in safe mode and clear the cache and nothing changes the issue.
Anyone has a way to help me with that please?
thanks a lot!

[Q] bluetooth pairing issue, how to solve?

Hello, so i bougth this great phone, but bluetooth pairing(+autoconnect) is not working at all.
So to the proplem. My opo IS paired with my alpine car stereo, but everytime i go to my car opo asks IF i want to pair it...and obviously it should just connect automatically since i have paired it earlier but no.
Is this some known issue with opo or my device just making me headtache?
IF anyone have had same proplems i would love to hear how you managed to fix it.
PS. All my old phones automatically connected to car stereo after pairing once, so its most definatly opo issue and not the alpine stereo.
Okey, i got this solved by doing 2 things, but because im stupid and didnt test it between these actions i cqnt say which one did the job or was both needed.
1. I cleared "paired devices memory" from my alpine stereo.
2. I cleared paired device list from my handset(opo)
Hope this will help someone else in future who got proplems with alpine receiver and opo.
Problem solved! bluetooth pairing and buffering issues
Hey problem solved
I had bluetooth pairing and buffering problems and now everything works perfectly. what I did was flash OPO_OxygenOS_1_0-modem-flashable.zip (you can find it somewhere in google docs..don't remember the link)
anyway after doing that everything works perfectly.
I am running cyanogen 12.1 nightly build from 20150601
then I flashed the modem.

Technical solution...too much ?
Hello All,
I too was facing issue with the Bluetooth connectivity. My headphone "Jabra Halo Smart" worked perfectly fine with other android devices but my OnePlus One. Issue i faced was that my at times my headphone would get detected but the headphone controls wont work. It was really irritating as i could not use the functionality of my headphones.
What i did was went into the Bluetooth options. Clicked on the setting icon beside my headphone and unchecked and rechecked the options.
Another action i performed was un-pairing the Bluetooth headphones from my device and resetting my headphones paired setting.
Third option was resetting the Jabra app that i installed on my mobile.
Fourth action is restarting your OnePlus device.
The above actions i performed in different orders. So one of them should surely help.
Suggestion provided by OnePlus Call Center: (which i did not need to try )
--> switch off the device
--> Press power+vol down button simultaneously
--> Select English language
--> wipe cache partition
--> wipe cache
--> reboot device
Advice while using Bluetooth headphones or speakers (especially Bluetooth devices having the functionality to connect multiple devices)...switch off the Bluetooth device and then switch off the Bluetooth of the host device (mobile, laptop, etc) and then connect the Bluetooth device to the other host device
Do not keep two host devices Bluetooth on...at times it causes to store the connection setting in the cache causing the Bluetooth device to act strangely. :cyclops: :cyclops: :cyclops:

[Q] Bluetooth reconnecting every 10 minutes

Hi all,
Been reasonably happy with the z3 so far but I'm having problems with Bluetooth connectivity, specifically in my car. I'm used to an iphone, which works flawlessly, but the z3 only seems to be able retain a connection for 10 mins before slowly reconnecting. It's become frustrating as it restarts some of my tasker profiles(?).
Has anyone else had similar issues? Are there any known fixes for this?
I've tried turning off stamina, wifi, bluetooth timeout, display timeout, re-pairing my device - nothing has helped!
Cheers,
Russ

The normal Stamina mode (not ultra) won't disconnect any connection just limit background process.
This can be bug in firmware So try to repair it by PC companion
+ and a question; is this happen with another bluetooth devices or just with car?
cause if it happen with car it can be software compatibility & ...
Thanks for the reply. I thought I would update.
I did try checking for firmware updates but I found a different solution shortly after. I downloaded the 'Xperia Z1 Bluetooth Fix' from the google play store, installed it and selected the Tune2Air device (when it was in range). Since then I've had no reconnecting problems! I have no idea what the app has done but it has completely solved the issues I was having. I suggest giving it a go if you are having similar symptoms. :good:

I get this all the time, constant every couple of seconds when connected to my Mercedes Comand unit..
I will download this app and test it out, hopefully it sorts it.
I have Volvo V40 and when I step in my car with my bluetooth on, I see on my Z3 Bluetooth connect and then disconnect. This repeats all the time. When I then disable bluetooth and enable, the problem is gone. I don't know for sure, but what I have see on my car's phone menu, although I get these disconnects on my phone , the disconnects are not noticed by my car. But again, I didn't look into that yet. Do you have similar problems?
Hi all,
Great to know im not crazy bcuz im having the same issues in my toyota as the volvo. My phone automatically tries to pair & sometimes this works flawlessly, yet other times it connects, stalls, then spends an age tring to reconnect & all the while the cars head unit still perceives a connection. What i hav noticed is that i get great connections (fast & from where i left off) when i pause before switching off my car. If i dont pause then i need to manually connect even if the phone says its pairing with my car. Iv come from a nokia n8 which worked flawlessly however i could not control the volume from the phone which i can do from the z3 & i was wondering if the problem could be with either the phone or stereo having conflicting memory of what was last played, volume level , etc. As there must be data stored somewhere on either or both devices.
Look at this page for an explanation of Sony, seems to be a problem from the bluetooth version of the car:
https://talk.sonymobile.com/t5/Xper...s-connecting-disconnecting/td-p/853609/page/2
I dont think its necessarily the car as the problem i outlined is resolved if i pause the playing music before cutting power. I should correct an earlier comment. My problem is with playing music from my phones harddrive via a player such as the native music player, vlc music player, music visualiser, etc rather than streaming music so im not sure what peolpe using cloud services or internet radio can do.
Does anyone know why pausing the music before leaving the car is necessary when in my experience using bluetooth 3.0 didnt require this?

No 'Media' audio option available when connecting Bluetooth to car's stereo.

Hello everyone, new here.
I'm desperate, been fighting this issue for some days now, to no avail.
My S8+ connects to my car's stereo (Blaupunkt New York 830) but displayed only 'Calls' and 'Contacts', there's no 'Media' option under bluetooth, so there's no streaming of it either.
Other devices such as the OnePlus 2, Huawai P9 are working without any issues.
I tried the following:
1. Cache partition wipe.
2. Resetting the car's stereo to factory default settings.
3. Upgraded the firmware of the car's stareo.
4. Updated my phones software including Samsung Connect.
I then read about an application called 'Bluetooth auto connect' and downloaded it. On some occasions, it DOES connect Media when using it, but it doesn't work all the time, on most cases it just connect and shows 'Calls'.
Please, is someone familiar with this app or issue and can assist me on this?
Much obliged!
Can't help you but....

I have never had any problem with media and bluetooth on mine. I would check and see if you have the radio and phone discover able to each other.

make sure you have the "Use System Wide BT HAL" checkbox enabled on the Misc page of Treble App. If not, enable and reboot.
