Pixel 4 xl bug - Google Pixel 4 XL Questions & Answers

Hello
When i connect ear buds and go to see a video or something else it starts the volume going down...Either if i put it up again it is going after a meanwhile down again.Except this sometimes for some minutes after volume dowm the lock button does not work.
I search around and i saw a lot of people ask about the same problem form 2016.
Do you have any idea how to solve this?
P.S.I use Sony headphones with the genuine pixel adapter from jack to usb c.
Thank you

Analogue headset controls work by applying resistors across some of the wires/contacts in the microphone. In short, the adapter is monitoring the voltage passing through the wires to detect the button presses. (I assume the adapter is entirely responsible for this on USB-C only phones)
My assumption is that your headphones are becoming faulty and are causing resistance on these lines even when you're not pressing the buttons on purpose. A less likely cause could be that the ADC(voltage sensor) on the adapter is faulty and is reading the wrong voltages and thinking a button is being pressed.

(HELP) xperia stuck in headset mode

its been a few months now and still no parts for my xperia so i cant get it fixed.
i have been wondering if its possible for someone to make a cab to turn off/on hardware headset jack or forcibly use handset speaker when in a call orsomething?
BTW i have tried all possible fixes using the "search feature"
Are you describing the problem where even though there is nothing plugged into the 3.5mm jack, the XPERIA thinks you've got something plugged in? If so, I'm having the same issue and have found that a quick way to fix this is to take the stylus and wiggle it about at the bottom of 3.5mm jack. This clears it up.
well yeah that worked before but my jack is kinda broken but working
some of the metal in the jack is really loose and the jack has a small broken part.
I had the same issue where my headphone jack reported that there was a constant headphone plugged in, it happened after I plugged a damaged headphone port into the phone.
It took many hours of research and a very intricate and careful dissasembly to fix the issue. I meant to take photos, but my primary camera ( my X1 ) was in pieces at the time..
Anyway, there's a little connector inside the headphone jack that makes contact with a pad, closing a circut, if the connector is bent too far out of the way, it doesn't make contact, and the phone thinks there is a headset inserted.
If your connector is actually broken, you'll have to jerry-rig a wire or something between the two plates to force it to know there's nothing in, but then you lose all headphone functions.
I had to bend the strip of copper to -exactly- how it should be, and it worked out for me, my phone is back how it used to be.
I hope this is of some help to someone, if it happens to me again, I'll document it properly, unfortunately I was in a rush this time, so I didn't have time to prepare properly, I went gung-ho and ripped it to pieces to get it right again.
what about a "software" method of fixing this problem?
doesn't windows mobile support turning headset off, from the registry, for example?
while using radio you can still redirect the sound to the main speaker, (this option is available on the radio panel) something like this feature can help us, i think..
Same problem here. I have tried some suggestion over here but didn't work. You may try it: http://forum.xda-developers.com/showthread.php?p=4485113#post4485113
I'm tired with annoying wire headset and now using a BT headset to be able make/receive calls.
Hope somebody can help us before we send back for repairing.
It happened to me, simply insert a clean "cotton buds" and pull it out again. I think, a dirt just got stuck causing some hardware short circuit or something. Don't know....but it definitely worked for me. I have tried those hardresets, softresets, tweaks and unfortunately none of them worked.
try to drain the battery and charge it back up.
Sometimes would be nice to combine some of the threads because they refer to the same problem
http://forum.xda-developers.com/showthread.php?t=529449
Anyway from my knowledge there are two reasons for this problem.
You may guess
1. Hardware:
This issue had been described very often. Of course the jack is a delicate piece of hardware, which could be damaged physically due to some bad plug or violent force.
2. Software:
It's obvious that the connection is controlled by a piece of software.
I realized that the problem had gone with the latest update.
Maybe it would be helpful to know about the firmware version you got on your phone.
P.S.: Anyone out there who may add this issue to the wiki?

[Q] Earphones Adjusting Volume Automatically/Activating Speech Options

I just recently purchased some new earphones (Sennheiser IE7) and when I plug these into my HD7, they randomly activate the speech recognition options (even though I have disabled this in the settings), adjust the volume and pause Zune playback.
Cheaper earphones don't do this when plugged into the phone and nor does a Bluetooth headset, it only seems to happen with these particular earphones.
Has anyone experienced this with other head/earphones or knows of a way to stop this kind of thing happening?
Thanks in advance.
I have experienced this also. When I use a male to male 3.5mm cable to my receiver the phone acts as if the -vol button is held down. This does not happen when I use a really cheap sony behind the head style earphone or the buds that came with it.
My guess is that its caused by the spacing on the connector (you know, between the little rings).
Try a bunch of earphones. If you're desperate, you could try splicing the connector of an earphone that works with the earphones you want to use. Otherwise I would say its not worth it; the audio components in the HD7 don't seem to have great quality anyway. I had a razr2 and the sound quality was better than the soundblaster in my computer.

Headphone port depth

Hey all,
So I searched the forum and found quite a few headphone port issues discussed, but no mention of my exact problem. And yes, I looked inside my port and scraped around with a toothpick... there is nothing immediately obvious obstructing the port- hence the need for my post
My headphone port seems to be short on depth. I have a pair of headphones with an inline mic. There are perfectly fine for listening to music (they even snap into place as they should). But the mic doesn't work. I don't use that often so i forgot about it.
Well the other day I bought a selfie stick (I know... I know... don't kick me! My fiance and I travel a lot and sometimes it is impossible to find someone to take a photo for you in front of a landmark). I bought a wired one to avoid the battery drain of BT (which I don't use much except in the car). Well, the shutter button on the stick doesn't work with my N6. I have 5 camera apps installed and all have the volume buttons mapped to the shutter...I tried it with my fiance's LG G4 and my old GS2, it works on both of them.
So while trying to trouble shoot this issue, I plugged my headphones into her phone and made a call... low and held, the mic worked. Next I searched the forums and Google and found the issues of clogged ports. Mine isn't. And I used a bright halogen light to peer inside. Nothing but port. So I measured it.
Here is the interesting part, my first measurements just involved watching how far the jack entered the port. I tried my phone, my S2 and the LGG4... the S2 and the G4 both ingested the entire jack. My N6, about 1mm was left out. So I measured by inserting a tooth pick and measuring how far it went in, sure enough, my N6 is about 1mm shallower then the others.
I did find one post here on XDA where people suggested that you had to press very hard to fully insert a jack. I tried, I nearly broke the headphones in the attempt... and no change.
Has anyone else had this exact issue? Were you able to solve it?
Has anyone attempted to replace the port?
Just a bump...
Anyone? TIA
Those mics don't tend to work in most cases if they work on an iphone vice versa, there are converters on dx.com as example. Sony headphones are known to work fine on android phones, I got a sony mdr-1 with an inline mic and controls that works fine on my n6.
If you want I can send pictures of the headphone jack connector when the back panel is removed, my back panel is currently loose after replacing the battery and I'm still waiting for the replacement ^^

Sure, the photo would be great.
The headphones I have work on two other Android devices, as well as the selfie stick. So it doesn't appear to be a comparability issue with Android.
Thanks!
So,
When I had a Moto X (V2) I asked moto about the volume controls and was told that they did not implement them, as it was not an Android standard feature. My guess it that it is the same with the Nexus 6 (I now use bt headphones, so haven't tried). My guess is that the microphone doesn't work on your headphones (try another set) and that the volume control over the headphone jack is not implemented.

Hey Note Dude.
Thanks for responding. It's an interesting theory, but I have an inline volume control on this headset that does indeed adjust the volume. So, it's really just the mic.
Thanks, though!

Automatic volume down issue when headset connected

Hello all,
I have seen this bug in many motorola phones. Pls find bug explanation below.
Everytime when i connect headset in 3.5mm jack, audio volume and ringtone volume goes down automatically and even goes to DND mode.
I found temporary fix by playing some audio while connect headset jack, which avoids this issue.
Anyone knows permanent fix, please reply.
It happens only when I connect headset of samsung with other head set it works great
So I thik it is just compatibility problem
I was also having problems with a Sony headphones. What I did was to remap the volume down button for headphone.
I think it's not a bug but feature. The phone maintains the status of volume level differently for the case when headphone is inserted and when the headphone is not inserted.
I don't have evidence for this, though but as much as I've observed, that's how it works.
The issue is due to the difference in architecture of 3.5mm headphone pin the inner architecture of the Moto phone is built according to it's headsets.
When you connect other headset eg. Boat it hits the inner plate which is responsible to lower down the volume as in some headsets there is option to decrease and increase the volume.
Power button will also not work by the time as the phone senses that lower volume rocker is being pressed simultaneously.
Solution : Screen off your phone plug in the headphones screen on and use it.

[SOLVED] Mi 9T Pro volume issue - volume goes down by itself?

Any help appreciated!
So basically I've had this happen ever since I bought the phone (EU version (Germany), one of the first models - bought right when released).
When I'm out jogging and listening to some music the volume randomly goes down by itself. Not all the way - it's as if someone comes and presses the vol down button once. And then I have to press the vol up button to bring it back where it was, only for it to go down again after 10 seconds or so.
(Just to clarify - I am not referring to the case where Android lowers the volume and shows the going deaf warning thing where you have to press OK in order to be able to raise the volume more).
I cannot for the life of me figure out what's happening...I'm literally holding the phone in my hand while jogging to make sure no buttons are being pressed while in my pocket or something, and it's still happening.
I believe it is somehow being caused by the vibrations, because I noticed the same thing is happening 1) when skiing (lots of bumps), 2) when riding a motorcycle (lots of engine vibrations), 3) when riding a bicycle and causing some vibration i.e. getting down from a high pavement or sth.
Has anyone had this issue, or any idea as to what I could do about it? It's quite frustrating Thanks very much in advance for your replies. For the record I am using wired headphones connected to the jack input.
Maybe incompatible headphones
100% this is because of incompatible headphones.
It's the headphones indeed. I own a pair of M6 Pro 2's with which I can use either a TRRS cable (so headphones + mic + answer button etc) or a regular TRS cable (just headphones, no mic or answer button), I've been using the TRRS cable all this time and had the volume down issue, tried using the TRS cable now and so far so good, been a couple of days and it's not happening anymore.
Bit of a bummer but quite happy that at least it's not an issue with the phone.
Thanks very much for your replies, much appreciated.
