Lg G4 H815 Bluetooth intermittent lockdowns - G4 Q&A, Help & Troubleshooting

Hi there, couldn't find anything relevant.
I have an H815, and it gives me some troubles with Bluetooth. About once in a week I wake up in the morning and my phone does not talk to Jawbone UP3 on my wrist and Kevo lock in my door and BT Stereo in my car.
Turning BT off and back on doesn't help, only reboot does the trick. Recent OTA upgrade to V10d did not fix it.
Has anyone had this problem? Because if not, it seems to be a hardware problem with my phone, right?

Bump, anyone?

Bluetooth no longer plays music through headphones, but calls still go through

Hey guys,
So okay, I am having an issue and have not been abe to solve it for a week now. Allow me to start...
I have the sony MDR-1RBT headphones. I've had them since last February and have used them without any problems. Connection, set up, and usage has always been a breeze. Until recently.
I started my day and connected my headphones like usual and it said they were connected. Cool. Went to play music and it played through my phone. Not sure why. Tried to make a call, audio went through bluetooth device. So they say they are connected and playing through the bluetooth device but is clearly is not.
Things I have tried to fix it:
power cycling phone and headphones
disconnecting and reconnecting bluetooth connection
gone into device settings and made sure media was checked for my bluetooth device
researched through the internet
followed what the person on this link suggested: http://forums.androidcentral.com/ge...r-playing-note-2-music-but-does-do-calls.html
The last step, when I tried it it connected! Yay! Then I turned the headphones and bluetooth off and went to turn em on again and it went back to not working. Tried the same method and it didnt work.
I am running on an LG G2 Rooted but not ROM'd. I know the issue is not with my headphones because I tried to connect the device to my Jawbone Jambox and it did not work on that either. I am not sure why it is not working.
I consider myself pretty tech-savvy and I am pretty upset that I haven't been able to figure it out. Let me know what you guys think.
When you go to your phone bluetooth setting with a list of paired devices, do you see 1RBT listed in there as "connected to phone and media audio"? This is very important because it sounds like it's only connected to phone but not media audio.
Do you have any other bt devices you paired up with your phone? Like wireless speaker or another set of headphones? Quite often if you have a few with power, there will be a race condition which one gets connected as media. But since you said music was playing through your phone speaker, I assume there is not conflict with another device. But nevertheless, just delete all your previously paired up devices in Bluetooth list to make sure there is no conflict. Remove 1RBT as well. After you remove everything, reboot the phone, and do a fresh pair up with 1RBT. See if that helps?
Also, try to pair up these headphones with another device, either phone or a tablet to make sure there is no issues with bluetooth radio on your phone. If you have access to another bluetooth device, try to pair it up with your phone to make sure everything is working as expected.
Let me know the results, and we will go from there.

I was having the same problem until I realized the volume on my jawbone itself was turned down.
Vectron's Suggestion Worked For My Bluetooth Headphones
I was heaving the same issue as the OP all morning. My Beats66 Bluetooth headphones were working just fine since I got my Alcatel Idol 4, with Android 6.0.1 (Marshmallow) phone through wireless provider CricKet, just 2 days ago. I primarily purchased the headphones for placing phone calls, just because most Bluetooth headsets I have purchased, and Android phones in general, are too low volume for my impaired hearing to make out. However, I do listen to music on them as well.
This morning as I am exiting a taxi, I hear music coming from my backpack. Somehow, something launched one of my music apps, probably the buttons and screen were activated while items in the backpack pressed against them. The settings said Media and Phone were connected to Beats66, and the phone did come through the headphones only, but the music would only play on the phone's external speakers.
I found this thread from a Google search, and Vector's post was helpful for me. I went to Bluetooth settings and highlighted Beats 66 headphones, then selected "Forget." I rebooted the phone, paired the headphones, and all my music apps play through the headphones now. Lets see how long it lasts right? Since this is a brand new out of the box phone, I did install numerous Apps, all of which want user authentication, permissions, and countless settings and permissions to interact with other Apps and phone hardware. Hopefully with everything getting set up the way I like my phone, (I'm particular about everything, or I just find the phone annoying rather than a tool), I won't make anymore changes that will alter the operating status of the headphones.
Thank you
I am experiencing the exact same issue on my LG G3 with my Skull Candy Wireless headphones. The headphones pair and phone audio works, but Pandora, Google Music and any other streaming audio app plays over the phone speaker. I noticed that I received a Carrier OTA software update on Jan 17, 2017 and am wondering if that is when it may have charged. The only way to resolve it so far has been to clear the BT cache. This is temporary fix as when you attempt to pair again it is back to only phone audio and no music audio.
My headset is not working with music until you turn off the phone audio just to play music. My phone is Lenovo A2010-a and my headset is Nia X2. Please help

Ever get this resolved? Still having this issue and so far only fix for me has been using Ti Backup to nuke all the bluetooth data, rebooting and then it'll connect fine. I also have Skullcandy BT headphones. Trying my car's BT too to no avail. Same problem. I think this is the same issue: https: //forum.xda-developers.com/lg-g3/help/bluetooth-calls-media-audio-t2837471/page4
I ended up buying an Amazon​ Moto G4 as it is slated to get Android 7.0. I honestly believe it had something to do with the last security update LG pushed out. Since the G3 is not updating I will attempt to root and rom at some point though recent search seem to show the LG G3 can't be rooted.

I rooted mine fine with Kingroot. Get Kingroot, root, install twrp and flash supersu then delete Kingroot. Worked for me at least.
As far as this BT bug with the G3 I don't have anything better than the data wipe workaround so far, so good luck with the Moto.
Thanks guys. I also had the same problem but i restarted my phone and my music is just playing. Yah!!!!!!!!!!

[Q] Bluetooth headset button support and microphone support (Moto Hint)

Hello, I've got the LG G3 D855 on Lollipop and I recently bought a Motorola Hint. It's a great headset and works on every phone i've tried it with except fully for the LG G3. It doesn't seem limited to this bluetooth headset either as I've tried multiple and they all have this issue. It seems that when touching the headset button (the one for ending calls etc) it doesn't do anything on the phone. On other android phones it starts up google now or allows you to choose what launches when pressed, but on this phone it doesn't seem to even register. It does work however when in a call to work for answering and ending but it doesn't register when not in a call. It seems as though the phone doesn't pick up anything when pressed, it even works on an iphone to initiate siri and every other android phone but no my G3 though I have heart it works fine on other variants which allow to launch either google now or 'voice mate' , and by the way voice mate isn't installed anywhere on this phone either,. Also, when using google now normally by opening it, audio runs through the headset but not the microphone for voice input, this only works on calls. I would root the phone and put another rom on it but you also can't root the G3 which is running Lollipop before being rooted also aha.
All very confusing I know, but would love to know if anyone else has this issue or know how to fix it!
Thanks

Exactly the same issue with my phone. I have been trying all afternoon (in vain) to get the phone button on the headset (Sena SMH5) to do anything. Similar to you, I can answer calls/end calls but in an idle state, the button does nothing. I called LG support but would have been as well not bothering as he suggested a "compatibility" issue as my headset is bluetooth 3.0, the LG G3 is bluetooth 4.0. I advised him that this was also the case on my previous Samsung S4 and that had no issues so the issue must lie with the G3 and in any case, bluetooth should be backwards compatible. I have also tried the bluetooth launcher app (which didn't work) and various other apps (utter, voice command,dragon) all with no joy.
I get the impression that the function is somehow disabled. The quest for a solution continues.....
LG G3 UK version running Android 5.0
Similar functionality got broken on the moto g by an update to the google/google now app. A rollback the apps to stock fixed it until moto released a patch. Worth a try?
Somewhat of the same issue got a jabra head set and my d852 does not respond to media buttons like changing tracks or play pause buttons
Same here with D855 lollipop V20h-EUR-XX and Jabra Motion. The Jabra Motion is able to launch Google Now with all my other phones.
same here with plantronics voyager legend.. call button does nothing..any workaround now?

Bluetooth legacy compatibility issue

Hi folks, I have a 2006 BMW with bluetooth handsfree built in which is obviously quite old now, however this has worked perfectly for handsfree calls with every phone I've had from Nokia brick up to Galaxy S3 last year. However, I've now got a new LG Optimus G3 and find that it will pair and work for a short time but then will drop the Bluetooth connection when I pick up a call. This happens whether using the car controls or the phone controls, incoming or outgoing calls. Very annoying!
Anyone have any ideas for fixes? I've exhausted all ideas except trying a custom rom - however this is the only stock rom I've used in years that I'm actually happy with so I'd rather avoid this.

Bluetooth connections problems.

Has anyone encountered issues with connecting with a car bluetooth? My wife phone conntects with no issues.. She can use the cars remotes to make and receive calls.. Mine I have to pick a contact from the phone for it to work, it will not work with the car or my work truck controls.. It seems everytime it ask if my car or truck can access my contacts, I always choose allow, but nothing happens, but it works with the wifes.. This is with the Lollipop update, that we both have...
happened to me I just rebooted my phone and it connected, also check settings for that paired device

Got one to work, in my truck.. The car it worked for a while, then quit.. I will try it agian to see if it will stcik... Most likely caused by the 5.0 update..
I've noticed a Bluetooth problem that suddenly started in the last week or so. I upgraded to Lollipop when it first hit, and didn't have any problems.
Now, however, after Bluetooth works fine for awhile (I can connect to a Pebble watch, Bluetooth speaker, car Bluetooth, etc) all day long - then all of a sudden it can't connect to ANYTHING. Toggling Bluetooth off\on doesn't fix it.
Restart the phone, then everything works just fine for awhile. Until it doesn't, and I have to restart again.
Anyone else experiencing this pattern?
I've actually had the opposite happen. I have a iSimple bluetooth box in my car. I've never been able to auto connect with either VZW Note2 or 4. The CS rep told me it had to do only with VZW phones and he couldn't help me out. On another forum, another member mentioned he didn't have any issues with his older phone, so I dug out my old HTC Incredible. Sure enough, it would auto connect. Something changed with Lollipop, and now my Note4 will finally auto connect to the iSimple box. I tried using a third party Bluetooth app prior, but it didn't fix the problem.
Finally got the one in the car working as well... Because the wife and I have the same phone, I just simply changed the name of my phone and it works fine..
If your talking about the developer edition one rom update.. YES.. What fixed mine was wiping everything and redoing the one rom lollipop, then twrp, then installing Ricks Rom Lollipop, things have been perfect. I even addressed it in the ricks rom thread the week.
I haven't had any issues connecting devices but since Lollipop, when I am connected to a bluetooth speaker (car, bose, other bluetooth speakers) the audio gets choppy randomly.
I have done some searching and found others (LG g3) who had the exact same issue after updating to Lollipop.
I have tried rebooting, using different music apps, unpairing/pairing, forgetting the device ect and nothing seems to work. Anyone else having this problem after updating to lollipop? Anyone know how to fix it?

Bluetooth Headset Microphone Problems

This is a really strange one. Checking to see if anyone has experienced the same.
On my LG G4, when I turn on my Bluetooth earpiece, anyone I'm speaking with says they can barely hear me. The moment I turn it off and revert to using the phone or some other headphones that you plug in (not bluetooth), the sound returns to normal.
I'm stumped and am blaming it on the phone because the problems started the moment I got the G4. The bluetooth device works just fine with the Note 4.
I'm thinking of doing a factory reset but if that doesn't fix it, this phone is being returned.
Anyone else experience something similar?
On a set of lg time pros, and no issue here. Also fine in two different cars.
Bluetooth is way better and more reliable than my g3 was.
I have the same problem with LG G3 and Plantronics M165 Bluetooth headset. Did you manage to solve your issue?
