Bluetooth pairing issues - OnePlus 6T Questions & Answers

I'm having problems during the initial pairing of any BT device. The phone finds no BT devices at all. Turning BT off/on doesn't work. Toggling airplane mode fixes the issue for the time being and allows pairing. It's only slightly annoying since once the device is paired, it connects without a problem.
Is anyone else facing this issue? The update from this week didn't fix the issue. The phone is stock.

I don't have the same issue, but I can't seem to be able to pair the device with my car. It connects to both of my Bluetooth headphones just fine. The car name shows up in my Bluetooth devices list under pairing mode, but when I click it, nothing happens. Let me know if anyone else is having a similar problem.

I'm having the exact same issue with two 6Ts, one from T-Mobile and the other directly from OnePlus. Both are up to date with regards to firmware.
Its almost like the Bluetooth stack is crashing sometime after booting or cycling airplane mode because it works for a little while and then stops.

Same issue here.
Doesn't see some devices.
Constantly re-asks if I will share my contacts with my car.
My pixel 2 didn't have these issues with the same devices, so I know it's just the op6t.

Had this issue. Glad there was a work around. What a pain in the neck.

Same having BT issues where it loses the pairing and I have to repair device.

BT Connection Drop
I am having the same problem of connectivity dropping and then getting reconnected all of a sudden. Can anyone tell me how to fix this for now? Also, any planned upgrades in future for the same?

People, I need help. I can't pair my oneplus 6t with any Bluetooth device. Whenever I try to pair it says: couldn't pair with XXX because of incorrect PIN or passkey. I tried every possible solution I found on the internet (reset Bluetooth, reset phone, reset network settings, wipe cache, etc) and no luck. All Bluetooth devices are functional and I am able to connect them to my Samsung phone, but no luck with oneplus 6t. I am running oxygenOs 9.0.13 and none of my Bluetooth devices has the pin code. Please help, this is really frustrating ?

[Q] Bluetooth Devices Disappear?

I have been patrolling the forums trying to find a solution (or at least a thread similar) to my problem. I made the move from the G1 to the Vibrant in Aug. I was spoiled by it so it feels. I've grown quite custom to my Bluetooth devices being remembered by my phone, and not having re-sync them everytime i want to use them. I'm wondering if there is a fix for this, or is this apart of the Vibrant framework and i just have to get over it? Has anyone else been experiancing this?

Speak now or forever hold your piece. This is a huge nerd farm and im sure we can all put our heads together.
Are you talking about pairing or connecting the device? I only have one bluetooth device with my phone, and the phone has no problem staying paired to it. I do have to reconnect it when I turn on bluetooth, but that's all.
To clarify:
I turn on bluetooth.
My headset is shown on the devices list.
I press it once and it connects.
Device is ready to use.
Once, the device didn't show in the list while BT was off, but when I enabled BT the device was displayed.

What i mean is, I normally have more than one BT device connected. More specifically my BT headset, and my car BT stereo. I used to be able to have both devices remembered in my device list. But now my BT Headset is the only remembered device (and sometimes, it too will disappear. Now i constantly have to re-sync my stereo. However when a re-sync is needed, i don't have to pair the devices.
On my G1, this was not an issue. So any ideas?
I have my laptop, headset, and stereo headphones paired to my phone. Haven't had any problems, they all remember fine. However, I sometimes have to disable and re-enable Bluetooth because I have a custom name for my device, and sometimes when the phone boots it forgets that it has that name and goes back to calling itself SGH-T959. I don't know if this is related... just throwing it out there.

This does help a little. Perhaps because I am still stock, I am having this issue. What ROM are you using?

I've had the problem on stock JFD, JI6, and on Bionix with JAC Voodoo kernel.
I'm having the same problem with my car's BT system. I thought it was my car till I read ur post. What happens with me, is that the car (which should connect automatically) will say that there isn't a phone available. I will then open Bluetooth settings (on my phone) and see that there are no devices listed. After cycling the BT off then on, my car will show up again, and will connect......strange

Exactly my issue. So seeing how i am not alone in the issue, does anyone know a fix or how to resolve issue? It's not a BIG problem, bnut it is annoying to have to re-sync everytime i get in my car, (or send files from my iMac to my phone).
+1 for the vibrant forgetting my bluetooth devices. I'll open my headset and I hear it say, "Ready to Pair". It's not a big deal, really-- all I have to do is turn bluetooth on, then turn it back off and all my devices repopulate. But it is an annoyance.

Bluetooth issues since security update

Hello,
I have noticed that since the security update I am having issues with my bluetooth. It will not automatically reconnect to paired devices like my car and headphones. Sometimes it will connect but the option to transmit phone/media audio is unselectable. When this happens, it appears to be connected, but the music will come from the phone, not bluetooth connection. The only solution I have found is to reboot my phone. Is anyone else having trouble with this? Totally stock.

I have been having the exact same issue and the only fix has been a reboot.

You're not alone. Seems there is a workaround.
I'm experiencing the same issue with any BT audio device it won't stay connected to my Android Wear.
What version? I'm on 25.211.1 reflashed modem and Bluetooth package things are fine so far.

XT1572 Bluetooth: Phone audio won't turn on without reboot (after updates/recharge?)

Hi all
I'm having this strange (but really frustrating) Bluetooth bug on my Motorola Moto X Style (XT1572) with Android 6.0. I already tried restoring the Phone to factory settings and without any extra apps but the issue persists. It just suddenly started happening (about a month ago).
Nothing has changed in the bluetooth devices that I use with my Phone. I connect my car using Bluetooth and if I'm not in my car, I use a Bluetooth hands free kit to make and receive my Phone calls.
About a month ago my bluetooth started acting weird. When I'm in my car and want to make a Phone call, it starts the call on my Phone but then my car says that something went wrong and the call couldn't be initiated, although the call is continued on my phone. I do receive my text messages on my car and can also sent them but I'm unable to make/receive Phone calls.
When I receive Phone calls, they don't come up on my cars media. However, my Phone says its using Bluetooth for the call and the bluetooth connection is up. When I'm having this issue, I can not disconnect the Bluetooth connection with my car on my phone. It refuses to disconnect and I can not switch to any other Bluetooth device. The same goes when I'm having the issue while connected to my other Bluetooth hands free kit. In the advanced bluetooth settings of the bluetooth connection on my Phone, I also noticed that when the issue occurs all Bluetooth functionality is checked (eg. 'Media audio'), except 'Phone audio'. 'Phone audio' is not checked and it refuses to check it (however it's not greyed out). When I tap on 'Phone audio' in order to enable it, you see it getting checked for like a few microseconds and then it instantly gets unchecked again.
The only remedy I found is to power off and start my Phone again. Very frustrating if you want to make a quick Phone call and that you have to wait 5 minutes each time or if someone is trying to reach you but they can't hear you and they keep calling back while you try to press the power off button and drive your car . Why do I even have Bluetooth .
I've noticed that when I keep my Phone powered on at night and let it charge, the issue is present. If I recharge my Phone while it's powered of, pull out the power plug and then power on the Phone, there is no issue.
It seems to me that it has something to do with the update process...
Any idea how I can solve this issue?
Previously I did had other bluetooth issues like sudden switches between the phone's speaker and the bluetooth hands free (without any clear reason), it would just switch the bluetooth audio off and on again. So imagine, I'm calling someone with my hands free kit and suddenly the sound is gone. I grab my Phone and hear the other person talking, I continue the conversation using my phone's sound, then the sound is gone again and I need to continue with my handsfree. Other times when the phone said it was using bluetooth audio, it actually wasn't and I had to select 'Phone speaker' and then bluetooth audio again to get audio via bluetooth.
I don't think it has got anything to do with my car's bluetooth or my handsfree because the handsfree works flawlessly with my laptop and the car's bluetooth also works perfect with my partners Phone.
I have the same problem as you and i've never found a solution someone could help us please
Anyone?

So basically since the December security update that was released in February? Yeah, we know... some people seems to have issues with Bluetooth since then, but some people don't, not sure exactly why. In the Lenovo support forums there is even some mention of Bluetooth issues (although they come short of admitting there is a problem) on the latest update.
If a factory reset doesn't cure it, then you just have to wait... we don't have the factory firmware images for the latest release to reflash and downgrading is a questionable solution at best. Hopefully the factory images become available or the Nougat update actually gets released and one of those fixes it.
Sorry, that's the best I have for you... which is basically nothing.

Bluetooth turning off

I got my PH-1 in the Sprint Lease deal. (What a deal for a high end phone!) I'm generally enjoying it, but for some reason Bluetooth gets turned off all the time. I have BT trackers and a smartwatch (Gear Fit 2), so that's quite annoying. Anyone else have this issue? I've googled around, but haven't found anything.
1) Have you tried to keep Bluetooth on, but no devices connected?
2) Try keeping Bluetooth on, but only one of the devices connected.
3) Do the same as #2, but connect the other device.
Basically just try to see which device(if it is the problem) might be causing Bluetooth in your phone to turn off. I don't have smartwatch connected to my phone, but I do use couple of Bluetooth headsets and they work fine and I haven't experienced Bluetooth disconnects.
that is odd, I have not had that happen
You are not alone. Mine is doing this too. At first I thought I was hitting the quick toggle but it isn't even there to accidentally hit. I only pair my Acura stereo and Jabra Elite Sport headphones to it, nothing else. But I used both those devices with my 6P and had no issues. I'm going to post about it in their subreddit, they seem quite active there.
I also have this problem. For no apparent reason, my bluetooth would be off maybe a few times a week. Maybe once a month, I would lose pairing to all my bluetooth devices and had to re-pair them all.

BT connectivity issues

Hi guys,
I have a Galaxy S8 Plus running on Oreo rooted, although I have an issue witv Bluetooth and I don't know if it's hardware or software related.
Basically, whenever I turn on Bluetooth, I can't see my paired devices, for instance I have a Gear S3 watch and whenever I turn on BT my phone cannot detect it even though it's already paired, the only way for me to connect it is by launching the Gear app and clicking on connect, and each time it asks for the pairing permission. I do also have BT earphones and the only way I can connect them is by resetting my earphones that way they can be detected by my phone.
This is so weird, does anyone else experience this issue?
Any help is appreciated. Thank you.
