Lg G Pro 2 D838 - Phone not detecting headphones (HELP) - LG G Pro 2

Weird thing started happening to my phone... When I plug in a pair of headphones (with or without mic) the phone does not detect that they are plugged in! Sound always comes out of the speakers. I've used apps like SoundAbout to force sound through the headset jack and it seems to do the trick but I'm still trying to find a proper solution for this problem.
The odd thing is that if I turn off my phone, plug in a pair of headphones, and then turn my phone back on, once booted the phone will recognize that it has a pair of headphones plugged in and everything will be fine. It doesn't work when I unplug and try to replug. It only detects the headphones on boot.
1) Is there a solution to this?
2) Anyone know something about mechanics of the 3,5mm jack? How all of this works? It seems that on boot it always tries to check if headphones are plugged in but I suppose that something mechanical in the headphone jack must trigger the check after boot...
3) I have cleaned the jack properly so dirt is not a problem. I have also tried different headphones and none of them are detected.
4) I think that problem is not software related. I have booted my phone in Safe Mode and problem is still there.
If anyone have some suggestion please help!
Thanks in advance.

EDIT: It was obviously a software problem. Yesterday I have updated my phone to new firmware v20b (SEA) and now my headset is working properly. When i plug in my headphones there is an icon in notification drawer showing that they are connected. After an upgrade of firmware I lost root so I suppose that somehow that was the source of this anoying bug. Maybe one of the apps that aquire root privilegies was causing this but I have never managed to investigate what's really going on. I tought that it was a 3,5mm jack (faulty hardware) problem...

[Q] Issue with bluetooth earpiece Latest Vegan Tab flash

Getting a "Paired but not connected" issue with my bluetooth ear-piece and I've tried everything to get it to connect, even force closing wiping all the data from the bluetooth application and rebooting several times. I've only had this problem since switching from cyanogen mod to vegan tab (Love vegan tab btw) does anyone know some fixes or solutions?
Thanks in advance :3
come on :\ doesnt even one person have a suggestion?
I was able to pair my phone with the Vegan Beta 5.1 gTablet without issue...
I just bought a new headset and will try it and let you know...
Working fine for me as well but when I disconnect I have to re-boot to get audio over speakers on the GTAB
hmmm, thats really odd, maybe my headset itsself is being stupid. Thanks for the feedback guys.

I've found if you plug and unplug a regular wired headset into the headset jack, thst usually fixes the audio be muted on internal speakers.
bluetooth help
I am having the same problem. Tried 2 different headsets, netbook, and my moto droid - but everything says "paired but not connected". nothing works! please help
may be a direction for a fix; DEVs could you clarify for us
I found this in a post today by enigma0456:
More research finally revealed something. BlueGPS4droid at sourceforge not the market. So, the external gps was "paired but not connected" until there was an application (bluegps) to "connect" to. Once that was installed I turned on the bluetooth and it immediately saw the hollux remote gps receiver. Tested it with Maps and it worked beautifully. So theories:
1. If there isn't an app waiting to use the bluetooth device it will pair but not connect until something asks for it.
now I realize this has to deal with gps but as i understand all phone apks have been removed that can be and not lose functionality in order to save battery life in Vegan 5.1 so if the above quote is right then there is no app (phone.apk etc.) to ask for the use of the ear piece and thus the paired but not connected issue.
now some people have mentioned not having issue getting their BT headset to work and maybe this is because the headset offers another use in their programing like they are designed to work like headphones or something and then there would be and app to ask for them and so they connect
the ones that do not work on the other hand like mine are only designed for phone audio; ever notice that on your Droid cell that your headset will say connected to phone audio, well in our case if the phone.apk/s are not there then there is nothing asking to connect to it.
DEVs are there any ideas to get functionality back even it that means adding back the phone.apks--and is that possible to do with our re-flashing a rom like side installing it or an update.zip
Thanks

There is an app on the market, called "headset toggle widget" and that will do the trick and unmute your speakers
Possible workaround...
Don't know if this will help but, after I paired my BT headset with GTAB, I then paired it with another device (my phone) after which GTAB started giving me the paired but not connected message when I tried to connect back to the GTAB. What worked? Well, now before I select the headset device in GTAB's bluetooth device menu, I put the headset itself back into pairing mode. THEN, I select it in GTAB's bluetooth device menu and voilĂ , it connects. Downside, I have to put the headset into pairing mode everytime I want to connect it to GTAB. (Haven't bothered trying to unpair the headset with my phone yet to see if it makes a difference.) Hope it works at least as temp fix for ya.

[Q] Odd sound problem

Long story short, I just picked up an AT&T HTC One X(Stock everything, S-on, not rooted) off ebay as a "fixer upper". The seller said the speaker and microphone wasn't working and included the parts. After changing them out, still no sound. I have also tried syncing my bluetooth headset and I don't get any sound through there, nor do headphones work, videos won't play. When I attempt to use voice search, the Google Search application crashes and doesn't give a chance to record anything.
I have tried doing a factory reset through the phone and through the bootloader, but the audio problem still exists. I think the phone had water damage, I need to clean up the board good first. Is there a chance that only the audio processor shorted out? Does anyone know where this chip is located?
Firmware version 3.18, running 4.1.1
So I have given the board an ultrasonic bath in M.E.K and gave it 24 hours to fully evaporate. Put the phone back together, but the audio still doesn't work at all, even replaced the bottom mic/back speaker ribbon. And also usb doesn't work in the phone, or fastboot. The computer just see's an unknown usb device when it's connected. Device Manager shows an unknown usb device, and under hardware ID it just says USB\UNKNOWN.
Anyone have any ideas on anything I could try to fix the audio, or the USB problem??

Audio jack detection issue since MM upgrade

Hello there.
Since updating to MM I have the following issue on my Z5: When inserting headphones or an aux cable, the phone switches back and forth between headphones and speaker for a couple of seconds, before finally settling on headphones and playing as it should. This is a problem because I have a Tasker task that relies on headphone detection and now it doesn't work properly.
I had the issue with the small apps after upgrading, so I already did a system reset, which solved the small apps issue, but not the headphones issue.
Already tried disabling SmartConnect and booting in SafeMode. No luck.
There is apparently another person with this issue on the Sony forums, so I'm not the only one.
Anyone know a solution?
Cheers,
Alex
I have the same issue, but only with the aux cable. When I connect my earphone, everything seems to be fine. So I think maybe the phone has some issue with one particular model of aux input? because there are several type of aux plug now.

I have had this problem with other Z series phones but not the Z5 yet.
As reported above my phone when I plug just headphones stereo only (two contact plug) into the phone gives me an ear icon for headphone optimisation and with an automatic headphones actions.
If I plug a headset in (three contact plug) I get additional headset options, plus automatic headset actions.
My guess is you have a conflict with the Sony built in functionality and the Takser task you mention.
@xperia z3 I have only had this happen previously if my headphone hadn't fully located in the headphones jack
So, how can this be fixed?

my guess would be try to disable any apps trying to hijack the sonys built in process and see if that fixes the issue

I have done a system repair through PC Companion and the problem is still there, on a fresh setup, with no 3rd party apps. I'll wait a while to see if there's an update that might fix this, if not I'll have to send the phone in. Luckily I bought it in late December, so I have still time to use my warranty.
Edit: Oh, and the issue with the small apps is still there, I have found out that it's caused by active accessibility settings, in my case tasker, but others have that same problem with other apps.
i'm dealing with the same exact thing. i did a factory reset, and it still persists. at first i thought it was hardware, then i installed soundabout. when i force output through wired headset they work fine leading me to believe this is software related. really frustrating, not sure what else to do.

Strange Bluetooth issue

Hi you all, I have a non common bluetooth problem. My S6 is running Xtrestolite with android 6.0. My phone can connect BT to my cars, my earset and my soundbar to play music and it work well even on my earset. BUT, nothing for voice call, the call connect and silence for everyone. There is no voice at all, but BT is connected, and all infos on my cars radio like timer, mute and others work well ( okay mute cannot be more muted ). So I tried 1/8 headset for music it works, did not try yet one with a mic, but I'll do it ASAP. I tried to reprogram with odin default OS, with factory settings, and that way force all components to be re-write ( Bootloader, Radio , etc ), issue still present !!! Try to clean micro usb connector, nothing !! Try to clean audio jack, but wasn't really sure if it was well cleaned.
Do anybody here have an idea of what I could try, test or do to eliminates possibilities ??
I am thinking that maybe some corosion could be in the audiojack, somewhere and let the phone think that there is an audio jack connected, and then sent the voice to it...but how it could be tested before to try to open the phone to clean it properly and risk to damaged the LCD ???
Thank a lot for all of your advices

Not your typical headphone jack issue.

Hi guys im looking to see if anyone has any input on this issue.
Firstly the phone is a Pixel 1 running the current android beta. the phone works as it should but since the last update during the day if im listening to audio with my wired headphones i get a loud pop and all audio to the headphones is disabled but the song/podcast im listening to continues to play on (no sound), ok i thought maybe the usual lint in the port, so turned the phone off and i cleaned it out (very small piece in there) . Headphones worked for a bit again the POP again and the same thing happened. Im starting to think it may not be the actual port as restarting the phone lets me use the jack again, which leads me to think its a software issue as apposed to hardware??
So so far ive:
-cleaned headphone jack
-tried an alternate pair of headphones
-done a factory reset
If anyone has any input that would be great, the only other thing i can think to do is remove myself from the beta and go back to standard?
Thanks in advance
