Loose Headphone Jack - LG V40 Questions & Answers

Does anyone have a loose headphone jack? I just got my V40 the other day and when I went to plug in multiple pairs of headphones, they all slipped in easily without any resistance or noticeable click. It produces audio, however if it is slightly moved or rotated, it is enough to pause any playing media. I'm assuming it thinks it's disconnected at that point. Audio is one of the most important features for me. It's a shame I'll probably have to RMA it. Any thoughts on the matter guys? Thanks!
Edit: There is no problem. Apparently I had had to exert more force than I thought should be required. I tried without a case on and was able to fully insert the jack with a fair amount of pressure. After doing so, I put back on the case and was able to use all my headphones. There isn't a lot of clearance, however being firm with the pressure exerted, all my headphones were able to be fully seated. That's one tight Jack! Also, I'll leave a quick review with the headphones I currently have available. On another note, I wish that the audio settings would provide information regarding if the dac/amp is providing high or low gain, as well as offer the ability to toggle it on or off. If you have any questions, feel free to ask.
Tested Headphones (Hi-Fi Quad DAC Enabled):
Meze 11 NEO IRIDIUM (IEMs): Easy to drive (Energy Efficient) - Loud, yet comfortable at volume 50*
Audio-Technica ATH-M50x: Easy to drive (Energy Efficient) - Loud, yet comfortable at volume 50*
Sennheiser HD 6XX: Easy to drive (Energy Efficient) - Loud, yet comfortable at volume 50*
HIFIMAN HE4XX: Harder to drive (Not Energy Efficient) - Still sounds absolutely amazing regardless - Volume at 65 is comfortable, 70 loud, 75 uncomfortably loud
*Recommended highest level of safe listening volume is 50. Once exceeded, you will receive a non-intrusive warning (not a dismissive window) each time saying that higher volume can damage your hearing. Volume limit is 75.

I have been having loose headphone jack issues. I am caseless now and fully seated. I pushed quite hard and am getting a stereo signal. Still quite loose and gets knocked out of the jack with even slight movement with the headphone cable... Quite annoying and not sure if there is a fix for it.

Take a pair of pliers, and flatten the end of a toothpick (I find it helpful, but not really necessary). Then dig around in the jack for lint with the toothpick. I had the exact same problem after about a year, use wired high end phones all the time...apparently over time I packed some pocket lint in there. I had lost the noticeable click and also easily dislodged enough to pause the playback. No problems since cleaning it out. (also might help to turn it upside down while cleaning). I like the toothpick because you can dig around without much risk of damage to the inner components of the 3.5mm jack.

Diamond headphones

Not sure if this has been mentioned before but...
After discovering for myself how quiet the sound was on the headphones that came with my diamond i done a small and simple mod (if you can solder) to increase the output.
Take off black rubber ring on ear piece
pull speaker out, i just picked it out with my nail
remove surface mount resistor (small black rectangle thing)
bridge the connections with solder
repeat on other side
Basic stuff with a noticable increase of sound
"Lowering" the resistance should increase the treble tones. Didn't know that's how manufacturers did things.
My HTC headset work fine. I need to keep the volume to minimum.

Saved by the Headphone Jack

Today my phone slipped out of my pocket. It slid out while I was attempting to change songs. I didn’t even look down. Just waited to hear the sound of it hitting the ground. Thankfully I never heard that sound. I looked down and the phone was dangling inches from the cement; saved by my headphone wire.
Question 1) Is this by design? The female/male connection of the 3.5mm jack seems unusually snug*. The USB by comparison sometimes falls out.
Question 2) Are there any apps that utilize the volume rocker to change the songs on the music player?
*that's what she said
I think you just got lucky *
I order to give good audio quality, the jacks need to be snug, better connection. I've seen many instances where I'd need to replace headphone jacks in computers because they wouldn't snap in firmly and not make good connections. If you held it at the right angle, music would play, but not without crackling and popping occasionally.
I have no clue if there are any apps. I imagine that would be more a limitation on the plug portion than the programs. The Aria did it, but I know there are particular types of headphones that have them built in that speicifically will/will not work with the phone. Just have to try.
*that's what I said. Just now. See, I said it. Earlier in the post. First line. See?

The Diamond AUDIO thread

Here's my first try in a quest to make the Diamond into an usable audio device. This will focus mainly on earphones, but if i get annoyed enough by it, there may be some hardware mods to the internal speaker (that is, if i actually decide to keep the phone).
I think we can all agree that the Diamond sounds like garbage. It's stupid loud but stupid thin. It's like listening to piezo tweeters. So, is it possible to change it? Well, there is hope. I want to share my results so far. This is for the supplied earphones but as soon as i have time i'm gonna hack a 3.5mm jack on the handsfree and test various other 'phones.
I threw the earphones on TrueRTA and was horrified of what i saw. But with some serious tweaking of the EQ, the graph started to look better. Anyway, jump right in and set your Audio Booster like this:
+6 +6 +2 0 +1 +2 -6 -6 -6 +3
This will take a fair chunk of loudness away, however i still find it plenty loud (and i like to listen loud, believe me). The distortion limit is 50-70% in Windows Media Player (depending on song) with the system volume at the middle bar. Now you can actually hear bass! Incredible. The next best thing you can do is get a pair of those foam buds that go over your earphones. This will make them couple tighter to your ears (basically that's why in-ear phones always have more bass, you can have the same effect with just those foam buds). Try it and you won't be disappointed.
Whoever has tried this, let me know if you like it. If you do, i'll post some before/after graphs too, so you can also see what you hear. Edit: I just noticed that the ROM i was using was volume modded. On stock settings distortion sets in at 70% media player volume with full system volume.
You can get 3.5mm adaptors on ebay for not much. I got one recently one with a microphone for about £3 I think. Then you don't need to modify you headset
I can't ebay since i don't have a card to put money on my paypal, besides, shipping costs to RO are quite expensive too. I found such an adapter locally, but for $15... i'd rather slice the headset thank you.
Heads up, good stuff coming.

[Q] Will the unprotected headphone jack be waterproof with headphones plugged in?

I'm wondering how Sony managed to leave the headphone jack unprotected and still achieve ip58? Which is the highest rating and would even mean continous submerging (albeit they limit it to 30 minutes for security reasons?!)
Is this a possible weakness, may corrosion set in? I've heard stuff like that from the Galaxy S4 active.
And also, will the headphone jack still be waterproof while headphones are plugged in, e.g. when running and listening to music and then rain sets in?

lol what kind of question is this. If it's water proof exposed, logically it doesn't matter whether jack is inserted or not. It's not like the jack rips into the device lol

I don't think the question is silly. I was guessing when the headphones are plugged in, they are making some kind of contact inside the connector, thus a small amount of electricity flows and you can hear sound. And this may be a differenting factor compared to no headphones plugged in and in terms of waterproofness. Maybe the manual gives a hint once it is released.

Well, when you insert a jack, one of contacts inside the female-jack acts as a switch. So it moves back and the spring action holds the jack in place (also allows the device to detect the jack is plulgged in).
So, you're right, inserting the jack would cause a minor movement inside the female-jack housing. But given that Z1 is protected only to 1.5metres depth, I don't think there's enough water-pressure there producing big enough force to create a gap in between the male-jack and the female-jack contact.
And in-terms of you mentioning current flow, that has got nothing to do with waterproofing, that's just electrocution. But even so, the current exchanged between the male and female jacks are so low, you won't get electrocuted lol
Z1 will still be waterproof & completely safe with headphones inserted...but I can't say about the headphone/headset itself as that will have to be waterproof too, otherwise there will be a chance of the headphone getting short-circuited which in-turn could damage the phone via the surge through the jack/socket.
i recommend the Monster iSport headphones, They are perfect for this, They are completely waterproof and it has a remote to control calls, music etc. (volume buttons only work with iphone)

cool I can make calls under water
to the OP - I can understand why you asked the question and I believe it has been answered - yes the phone remains IP58 with headphones inserted

[Q] Audio jack not working

My 3.5 mm audio output has been having increasing problems and it won't recognize most jacks anymore, including my earphones. Do you know of any trick to make it work, or would I need to replace the part completely to have it working again?
I think it depends on the kind of issue you see.
Example:
My audio jack was not working when I received my used Droid 4 from the USA.
I realized that my headphones are not deep enough in the phone. When I push them in a bit more they worked properly, but hey flip out as soon I touch the cable or I move.
1. Look if the Headphone jack is dirty and clean it up: h**ps://motorola-global-portal.custhelp.com/app/answers/prod_answer_detail/a_id/85247/p/30,6720,8096/c/8149,8172
2. If its cleaned and still not working its probably a hardware issue. ( Now you need to find whats broken / not working )
- A weak point is that the feeds of headphone jack are only pushed against the mainboard. I can imagine that carrying the phone in the pocket will bend that feeds. Meaning if you try to use the headphone jack outside of the pocket it will not work properly. You can try to push from the outside of the headphone jack to see if they work then properly. If yes... you need to disassembly the phone... and bend the feeds of the headphone jack back so that they get contact with the mb again.
- In my case after cleaning the headphone jack, the plug still didn't fit into the jack properly. I didn't want to open the Phone since ifixit says its a mess. So I tried to fix it without replacing it. I pushed a pice of toothpick into it to widen the deepest part of the jack. That fixed my Headphone jack. But the risk is there that you completely mess up the jack and you have to replace it completely.
Try at your own risk!
It is VERY easy for lint, dust, and grime to get stuck in the audio input socket. It's happened to my phone several times, since the audio jack isn't covered by any sort of cap. If you turn the phone off, shine a light into the socket, and (gently) dig around with a safety pin, you should be able to get most of the gunk out. It'd surprise you, how much lint can get stuck in there!
If you can find something to cover the audio input socket with, even better.
It was just dirty after all - I had like 3 mm worth of lint inside
I was worried it's some HW issue because different jacks responded differently... Glad it's not I use BT HF most of the time (with 3,5 jack output for headphones), but sometimes I like to plug the phone into my speakers, plus BT isn't that comfy for watching video...
Pipe cleaner wasn't very helpful, but a pin did the trick
Thanks for your help, guys!
