Bluetooth On Android 10. - OnePlus 7 Pro Questions & Answers

I have a newely replaced t-Mobile 7Pro on the international v10.0.3. I paired my Galaxy Active 2 and it worked for a few hours and will no longer connect. I can try to manually connect, but nothing happens. I also noticed some drops with my Jabra 75+ headphones.
Looking around the forums, it seems like Bluetooth has some issues on Android 10. I reverted back to TMobile's v9 firmware and everything works again. Maybe a bug in V10?

I know someone where Bluetooth connects to speakers, headphones etc. But only heard white noise, no sound. No fix yet
International variant of op7

Interference with bluetooth voice calls

I always use my bluetooth headset when talking to family and friends(due to the length of time, hate holding phone). Since, I switched from my nexus one people have griped about the interference/noise they hear when I'm on my bluetooth headset. It is not my BT headset as I've tried a few(motorola S305, and two smaller bluetooth earpieces), all of which exhibit the noise. I was wondering if anyone else has had this problem ?
Running the Galaxy S I9000 ROM rooted.
Everyone complains about hearing me whenever I try to use a headset. Seems like the stack sucks or the radio is terrible.
Got the same problem. My bluetooth calls are loud and clear on my side, but everyone on the other side complains about static noice and I sound very distant.
I tried the original ATT rom (stock unrooted) and the most current 2.1 that is available for download. No difference.
Any ideas what to try to remedy this?
I haven't noticed anything like this on my Motorola S9-HD headset.
I have noticed sometimes it will cut the music every once in a while, whereas my iPhone never did.

This is a known issue with the I9000 ROM... Bluetooth doesn't work well for some...
I'm running the stock rom... is that the I9000 rom?
None of my friends have mentioned such a problem when i've called them, although I've only made bluetooth calls a couple of times (including on the bus and at home).
Using after-market Nokia BH-503s.
I'm definately seeing the same problem on the stock rom. Not as bad as athe I9000 ROM but still bad enough for them to complain. Seems like it's made worse by the different roms/kernels we've been flashing but there's definately a problem.

I'm seeing similar symptoms, except my music cuts out every 30 seconds or so. My setup is a Kensington iPhone adapter connected through aux input in my car with an Anycom FIPO on the iPhone adapter (it converts the iPhone/iPod adapter into a bluetooth receiver). I then stream from my Captivate to the adapter and it works fine except that it cuts out every 30 seconds. Did you ever figure out how to fix it?
UPDATE: Just wanted to add that I figured out what was causing my problem: having Wifi turned on. Once I turned it off, my bluetooth streaming worked beautifully, with no hiccups.
Still have a problem with this. Stopped using my BT headset completely... sucks having this thing stuck to my head for calls.
I have encountered several problems:
Party can not hear me at all; though I can hear fine.
Party hears tinny sound to my voice.
Headset disconnects while playing music.
Using a Motorokr S9-HD. Works fine with Samsung A-737.
I too have the static problem. This phone sounds wonderful on my end, but everyone complains that that can't hear me! This is so far the only complaint I have.... I hope someone will have a fix, or come up with something.
I have this problem too !

Bluetooth Issues connecting in Car

In my corvette and my cadillac my bluetooth wont stay connected for music after i leave the car and return back into car, Ill have to delete it and repair to stream music bluetooth. anyone having these same issues with there Tmobile Lg G5? because if not ill return mines
I have a similar issue. I have Bluetooth headphones I always wear. And I have a Bluetooth connection in the car. When I get in the car it tries to play over the car (said it would play audio over the last Bluetooth audio connection connected the first time it paired) but I hear nothing. If I change the connection between either Bluetooth connection I get no audio. I can only get audio if I play it directly on the phone or I turn the headphones off, then restart whatever app I was using to play music. It is quite a pain.

try in your rolls royce and your aston martin and see if you can replicate the problem, OP.
[jk but we need more info: factory or aftermarket bluetooth receivers in these vehicles? how did they behave with connecting to different devices via bluetooth? mine is an aftermarket stereo and it connects automatically in about 30-60 seconds or i can just open bluetooth settings and select my stereo's name and its instant. never have to re-pair.]

In my car I am using a cheap usb Bluetooth dongle connected to audio in port. I connect fine. It actually connects very quickly and from much further distances as my previous phones. Main issue is the sound seems to go nowhere if I have more than one Bluetooth device connected at once.

I have the same issue with my JVC Bluetooth car radio... What I have done to resolve the issue soo far is turn the bluetooth off through the quick menu then start my vehicle, turn bluetooth back on and it works properly then.
I have my radar detector connected via Bluetooth and my car , stock radio 2012 camaro .. I will be listening to music then randomly it goes blank forcing me to wait for a disconnect and reconnect again to hear anything

Had This Issue With My Car and the LG V10 & G4 But not G5
Maybe just maybe there are 2 different chipsets for bluetooth. I had this issue you're talking about in my 2016 Honda HRV with both of LG previous phones, LG V10 & G4. Typically, they do fix this issue with updates however I think it might be "deeper" than that... if there's 2 different bluetooth chips being put into phones it might explain the issues that some people get and others do not. I know when I planned on getting the LG G5, I made sure it was not at the store where I would have to give over my Jump On Demand phone immediately, my S7 Edge, before I confirmed this issue was not present with the G5. At any rate, I lucked out I guess because knock on wood, no issues. Don't know if would could ever confirm different chips but hopefully they release a bug update to fix soon. :good:

Mine worked fine for the first day or soo then started having issues....Weird thing is that I never had issues with my V10 and the same radio
I have this exact issue... can't quite figure out who to talk to about it (ex. Marshmallow Android or LG support) I've tried more than 1 LG G5 phone and the same thing occurs across what appears to be all GM manufactured vehicles (of which I'm assuming doesn't necessarily have to do at with any manufactured GM vehicle, just coincidental.) Odd part of it is, when making calls through Bluetooth, that always works, no having to pair/unpair.
I too have wondered if this is primarily with GM vehicles. Had a rental Suburban that had the exact issue as OP. Luckily my '16 Canyon does not but then the reason I had the Suburban was because the dealer was doing the Android Auto update on my truck (among other things). Not sure if the issue would have existed previously in the truck since I didn't have the phone at that point. I've had no issue with Bluetooth on any other device though. On a truck forum I frequent though, others are having the same issue but with different phones.

the issue I have is when I have two bluetooth devices connected... so I have my hbs800 already on and streaming and I get to my truck and turn it on. At this point my phone now sees the Pioneer deck and connects to it, however randomly like 1 a week it will connect only call audio, not media. I've tried power cycling the deck, my headphones, basically everything but the bluetooth on the phone and it will never connect to media only call audio. I power cycle just the bluetooth on the phone and with no issue it will connect through media.
Having the same issue with my G5 connecting to my 2015 Colorado. Initial pairing music streams fine. Shut the truck off and turn it back on, everything reconnects, but no audio is heard. Have to completely unpair and delete connections and start over to get it back working. I hope this gets fixed soon!
Works fine in my Acura ILX stock radio
Seems to be a compatibility issue with GM products. Have the same issue with both my '16 GMC Canyon and a rental Suburban. Very irritating. At least with my Canyon I can plug the phone in and use Android Auto, which works well.

The BT is total garbage on the G5. I use LG tones at work. I'll be walking around the shop which can be noisy and music will just stop. After the machinery quiets I'll realize the music is playing from the phone speaker. On my way to work this morning I'm getting into The Sickness and it's just picking up and all the sudden the music stops and starts playing through the phone speaker. I pulled over and restarted my car, it reconnected so I took off again and 30 seconds later it did it again. It happened once before while playing Let It Go for my kids so I wasn't even mad about that but today I almost lost my ****...
How fo i connect my LG G6 to my Kenwood...it asks for passkey and o put in 0000 and say wrong passkey

Bluetooth weak signal with Mediapad X2

Just got a MediaPad X2. It was the 702L, but I followed the helpful guides here and I've unlocked and loaded KangVIP slim B211, so now its a 703L. Everything seems pretty awesome and I'm liking it. However, I've noticed the bluetooth seems to be weak and/or micro cutting out.
Yesterday, while listening to music with Bluetooth headphones, the sound frequently cut out even though the phone was close to the headpohones. When making calls with a Bluetooth headset, the other person says my voice fades in and out and has static.
I read on another thread here that WIFI might be interfering, so I turned off WIFI on the phone. The bluetooth seemed to get better, but my friend says it was still not good. I turned off the headset and used the phone itself, and he said the voice quality was perfect, so I don't think the issue is the phone itself.
Is there a way to boost the power to the Bluetooth signal? Has anyone else had any issues with Bluetooth?
Thanks!

I experience the exact same thing with my Bluetooth headset but was not sure if it was the headset or device. Now I'm thinking device!
Interesting. Today I discovered that there might be some interference coming from my Microsoft wireless keyboard and mouse. While on a call, I unplugged the wireless USB dongle and took the batteries out of the keyboard and mouse. The person on the phone said the call quality got suddenly better!?? Going to keep trying calls in different places to see if that wireless interference might be the issue.

Solve a bluetooth mystery. Audio stutters up close but is fine from afar

Since android 7.1 I can't use my bluetooth earphones with my Nexus 5X. I'm this close to selling up for a different phone.
I can pair my Nexus 5X to my Anker earbuds, but the sound drops out so much it's unusable, stuttering several times a second.
The weirdest thing though; the problem is worse when my phone is near my earphones, like when I hold my phone up to see the screen. When the phone in my pocket or across the room, it works OK.
The problem is also worse when the screen is on than when it's switched off.
Can anyone help solve this? The fact that distance helps makes me think it's maybe a weird bug related how 7.1 manages bluetooth power and interference? A Bluetooth LE thing?
For reference;
It's a Nexus 5X, currently running stock 7.1.2 beta.This problem began exactly after the 7.1 update.
I'm using Anker Soundbuds Sport earphones. It's not the earphones, I've tried another identical pair. They also work fine with other phones.
Bluetooth works fine with other devices; my soundbar, bluetooth speaker.
I've tried rebooting, full factory image flash, every wipe possible.
I've tried Lineage OS, including flashing that aptX mod.
Let me know if you want any more info.

Oneplus 6, 8GB 256GB ROM, OOS 9.0.2 (stable) - Bluetooth Issues?

Hello people,
I am using my Oneplus 6 since day one as (more or less) heavy user (kinda IT-Admin stuff, bit gaming, etc.) and I'm absolutely stunned by that phone, I'm always on the latest OP-Device since day one.
So... but I'm now struggleling with the Bluetooth Connection with my Headphones. I am using my Beyerdynamic Amiron Wireless with my Oneplus6 via Bluetooth.
Now the thing is - sometimes if I turn my head around, the connection is getting unstable and I can't enjoy my music. With my 6€ amazon Bluetooth dongle on my working-PC I am not experiencing this problem, even if I walk through the office here (+/- 5-10 meter), totally stable, not getting unstable. But if I am underway before or after work, or in the city - I am experiencing this issue with my headphones.
I already made a full reset (factory reset) and flashed the latest OOS 9.0.2 with the unbrick tool, just to exclude it could be an buggy update or something. I even made a whole reset of the headphones (and checked for newer firmware, but there wasn't one).
Have anyone of you any ideas about this? F***s me up right now...
I am unrooted, no magisk or any mods.
Cheers
Hi, I'm using the Sennheiser HD1 free, and the only problem i have is on PUBG i have a little bit of latency , even if they are aptx compatible, i'm on the last stable 9.0.02 and i have a 128/8 variant, but with music, videos or calls they are perfect, you tried to factory reset and debrick so i guess i have nothing to advice you for
good luck

When i connect it, it shows a toast and a logo of Qualcomm aptx
And also
from :https://www.theverge.com/circuitbre...s-on-impressions-comparison-bluetooth-earbuds
"The Momentum HD1 Free and CX 6.00 BT look virtually identical. The hardware for the cables, the in-line remote on the right earbud, the battery module on the left earbud, are all exactly the same — the two products even share the same FCC ID. Both headphones have Bluetooth 4.2 and support Qualcomm aptX and aptX Low Latency audio for higher quality playback, assuming your device supports it, which makes sense seeing as, again, they’re more or less the same."
I'm not test it yet with bluetooth headphones, but i don't have any bluetooth problem with my car audio and galaxy watch. OnePlus 6 8/256GB A6000
I have 8/256, am on 9.02. See frequent disconnection during calls made via car's BT. Not that it should matter but I have 2018 MB E350. No BT problem making calls with my wife's Samsung S9+. I did not have any issues with OP6 when I was on Oreo. Tried factory reset, clean flash, all the steps OP mentioned.
I'm on the 8gb/128gb not the 256gb and I have to issues whatsoever. I'm using Sony MDR-XB650BT headphones which are aptx compatible and an Mpow Bluetooth receiver (3.5mm Jack) my 2011 Pathfinder Bluetooth and my Samsung gear SEE frontier... all without any issues or drop outs.
I'm on 9.02 rooted with Magisk 17.1 stable with TWRP blue spark v986 v2 and EX kernel 3.02
I have the same issue and I believe it has to be because of low quality headphones, not the phone itself. Thought my nexus 6P was the problem but the issue remained on my new op6.
So get better quality headphones or it won't go away unfortunately

Beyerdynamic Amiron are not even close to low quality. That being said i am having the same problem with some low quality headphones and just assumed it was them.
But I am also having a problem getting any changes i make to bluetooth in developers options to stick. So not really sure what to think.

Didn't see what kind of headphones he was using, my bad.
But I still highly doubt it has anything to do with the phone anyway, since everything (at least what I use bluetooth for) else is working extremely well, just my low quality headphones has issues.
And at least from my side, since the issue remains from two totally different phones I think it's something else. If it's not hardware related to the headphones then my best bet is some kind of settings inside android.

I changed too the settings of the dev option but none of them seemed to get saved, try the OB rom or another rom to see if it's the stable one is the main cause
OP6/8/256 + 9.0.2 + cheap no name BT resembling Crapple earphones.
Stable connection but 600ms latency, exactly as under 8.1, 9.0, 9.0.1 stock.
Sometimes volume skyrockets and requires adjustment.

There's no such car as "2018 MB E350." They discontinued E350 in 2016.
Are you sure that you don't have a time machine?

LOL! It's E450. I still have 2015 E350- my son is using it (just turned 16, so only during the day with my wife in the car with him). Actually, BT disconnecting issue I mentioned happens in both cars. I may ask the service folks to look into this issue when I take my car for service next month. It does not happen all the time but get disconnected while I am still talking and have good signal.
OnePlus 6 w/ 9.0.2 - has been factory reset by clearing data and cache in recovery, as well as factory reset within Android.
My issue is with my vehicle's Bluetooth. Media playback is fine, however the vehicle often thinks that the phone has no signal, when it does have signal. When the vehicle does that, I can't make calls from the vehicle, but making or receiving a call on the phone itself will work through the vehicles speakers and mic.
No issues with my iPhone, or any other Android I've used. This is the first and only phone with this problem.
