No sound after teardown? - Samsung Galaxy Nexus

Hello,
I just opened my phone to change the charging port with a new one because the old one was so loose that charging the phone was a pain in the butt. And after months of waiting I finally decided to teardown my phone just like in one youtube video. I took a lot of risk and time and did everything the way I was supposed to do and I had a success! The phone booted up everything was working as normal and this usb charging port was just like a new. But sadly I started receiving SMS messages because my phone had been turned off for some time and didn't hear any sound. Most of the times it is on a vibration mode but this time it wasn't. The only thing I could hear was a little tapping noise that you can hear only once before the sound goes on and that's it. There's a vibration jsut as usual there's just no sound and it definitely is a hardware problem because I have it on my phone and also can hear the person talking through the front speaker but the bottom one is definitely not working and I have no idea why when I made everything like it was supposed to be (I guess). What do you think happened and should I open it and tear it down again? Even if I open it what am I supposed to do?
Thank you

Problem: Speakerphone always on... always.

I had a strange problem on Sunday where my phone was constantly sending the * non-stop. I tried powercycling and yanking the battery, but it was relentless. The key was still 'clickable', so I decided to disassemble the device and clean the key sensor. (I had disassembled it a while back to replace the screen, so I wasn't intimidated by this procedure.) I used one of the guides on youtube to take it apart, I gently cleaned the sensor with a qtip and reassembled the phone. And it worked! No more stuck keys
Now though, I have a new problem. All conversation comes out of the speakerphone. I can turn the speakerphone on and then off, warm boot, cold boot, yank the battery, adjust the volume properties, I even reflashed the newest Ricky 6.1 rom. Still, I get all audio out of the speakerphone. As far as I can tell it also is coming from the ear speaker, but the speakerphone is loud enough that I could just as well be hearing it instead.
The question is, is this a short? I'd have a hard time seeing it to be a s/w issue after I reflashed. Does anyone have any ideas what I'm facing?
bump.
I realize I'm posting a probable hardware issue to a primarily software forum. I wasn't sure where else to go. If anyone can suggest a different forum that I could post the question at, that would be equally appreciated.

i have same problem please help
take it to service - HW fault .. or if you wish to open device I can tell you what the test points are
I agree with JSP_M
You didn't have this problem before you opened your device. You have the problem now, since you have opened your device, so that obviously means that something went wrong when you opened it.
The audio output is one line. It diverts the signal to the earpiece or the speaker. These diversions are controlled by your registry, since you have reflashed your phone, the registry will have been cleared, so that is not the problem. Plus, you claimed you hear sound in the earpiece at the same time you hear sound in the speaker, so open up your device.
Trace out the lines from the speaker and the lines from the earpiece, if you feel froggy. Then, see if anywhere that shouldn't be touching is, or if something looks brown or discolored. This indicates a short circuit. I can safely tell you though, that something is touching somewhere that is not supposed to be. Listen to JSP_M, he sounds like he has some other points of interest for you test, once you get you phone opened up.
Hope this helps. Later.

Try to call the customer service line from Tmobile and tell them your phone is defective and they should send you a new one.
The loud speaker is harnessed in the back housing of the phone and the ear speaker is harnessed in the faceplate above the LCD. The pads that they connect to aren't even close to each other and are on opposite sides of the mobo. I have repaired a lot of Dash phones and I have yet to come accross this problem. Try cleaning the pads they connect to and make sure the contacts are making a good connection. Or, if you can live without speaker phone then just remove the speaker from the housing all together.
I'm having the same problem on my Wing (Herald). But I never took it apart. In addition Activesync will no longer work. It never connects but my computer makes the 'ding' and the PPC screen lights up when I connect it so it can't be a bad usb port. It seems like a software problem to me, since it recognizes being plugged in, just not the connection.
What are the registry keys that route the audio?
how can i edit register keys
and i get new ear speaker still same problem
thank you
Send it to customer service
I once had that problem.... I sent it to customer service, and i got a new phone in 3 days. You have to pay for shipping though.
Heeeelppppp

[Q] HTC ONE X LOW mic issue

Hi everybody, I've been googling and looking into all the posts (here in xda) I could related to my problem.
Currently I'm in Nepal, and bought a second hand One X International version; the unit was barely used with very minor wear signs. A couple of weeks ago I was driving on the road and it started pouring rain, made it home in about 5 mins. Phone did not appear to have gotten very wet, however I took the silicon case of and dried the screen with a piece of cloth. I forgot to turn the phone off and as everything seemed fine, I continued using it for the next couple of days.
Two weeks later I start getting complains from people I was on the phone with stating that they could barely hear me, but oddly enough at times they mic volume went up and all the sudden they could hear me crystal clear.
If I turn the phone into speaker mode then they can hear me, the same happens with headphones.
Tried getting rid of stock Sense (not sure what version I had, I know it was JB 4.1.1 and Sense 4+), flashed IceColdJelly 3.5.1
Also left the phone off in rice for about 2 days (it was too late to do it but tried it anyways)
My phone does not have warranty and I'm reluctant to send it into a Repair Center here as I've heard friends and their terrible experiences with them in here.
So I decided to open my phone to see if the MIC was clogged/dirty or something (plus I have the WiFi signal issue) but everything on the inside seems fine. The phone itself seems to have never been open.
The MIC still sounds muffled (no it is not completely dead), tried the stock android Sound Recorder and barely pics up my voice if I speak directly into it.
Could it be a software issue? If not, how can I test and know which MIC I need to buy???
Any help, tips or thoughts will be much appreciated!!!
P.S. I also tried doing a Factory Reset. Nothing changed
problem apparently solved
so last night I managed to restore the phone into it's original state with a nandroid backup. Haven't been able to fully check the issue properly because I did not put the phone back the bezel yet. But now volume in video recording is normal, and have been told that I can be heard on a call

Sony ZL c6506 rear external speaker is not working for any sounds

I purchased a used Sony ZL c6506. The ZL would not boot, it would only show a steady red LED when connected to a charger. I figured out that it is likely a battery problem as the person who sold me the phone told me he was using it as a GPS when the battery drained and the phone turned off. He tried charging it and it would not charge or boot.
I replaced the battery and it booted. I upgraded from 5.02 to 5.1.1 as a test to make sure the wi-fi was working. The upgrade installed and it was running stock 5.1.1 (10.7.a.0.222). I did a factory reset from the ROM settings to clear out the previous owner's data and apps. After setting up the phone, I went to change the volume for alarm and ringtone. As I moved the volume slider around, there was no sound from the external speaker. Rear speaker doesn't work in safe mode either. Headphone jacks work properly and, when I remove the headphone plug from the phone jack while playing a song, the song pauses until I press the play button to resume playback. No matter what I do, I can't hear anything from the external rear speaker.
I took the phone apart a few times and everything looks okay. I even connected a tiny speaker and connected it directly the what I think are the speaker connections on the phone and still nothing, even when booting with boot sounds enabled in the ROM settings.
Given everything I have described, should I buy a replacement loudspeaker piece for the phone or am I just wasting my money?
Any troubleshooting would be greatly appreciated.
Thanks for reading.
Decided to buy a replacement buzzer. Hopefully, the replacement will fix the issue; otherwise, I will have to use the phone as a media player

The speaker have a screw that needs to be tight correctly to work. here is a video on wich screw I am talking about. https://www.youtube.com/watch?v=7yADs4OsAXg
Got the replacement speaker and still no sound from the phone. Everything works perfectly (vibration, headphones, wifi, bluetooth, etc.) except sounds. Factory reset a couple of times and nothing.
Time to move on from this issue. Parts are too expensive to keep trying to repair it so now I have a nice media player
i had the issue with battery and speaker...turns out the battery issue is common with zl..
solution for battery:remove the battery connection to board and reconnect it...(this happens alot to me especially when im using camera)
solution for speaker: the screw on the speaker loosens for some reason and results in disconnection....i used a piece of paper to hold it tight from back
hope this helps for u

M8 top speaker not working

Just got my brand new m8 and after using it a bit I noticed the top boomsound speaker wasnt working. Tried some basic troubleshooting and using it in different apps in no avail. I can hear someone in a phone call no problem though, but if I use the speakerphone or use the phone to play music or something like that it doesn't seem to be working (or maybe be extremely quiet??).
I haven't tweaked the phone yet in any way, completely stock Android 6.0 that it shipped with.
Edit: The top speaker works but it is much, much more quiet than the bottom.
I'm really hoping this is a software issue, any way I can test that out?
Bump. Can someone running marshmallow please test this out real quick for me? Play this on max volume and see if left is considerably quieter than right - https://www.youtube.com/watch?v=hTvJoYnpeRQ
Thanks guys! Gotta love that over a hundred people that saw this and couldn't take about 30 seconds out of their day to try this out for me
Anyways I'm probably sending the phone back. Gonna have to go back to struggling with my old HTC One S while I wait for a replacement.
Actually I'm having a very similar issue.
My phone had perfect speakers since I got it but recently it fell face down and the display went boom! No cracks anywhere though.
The service guys replaced the display but now the top speaker had a very loud crackling, at the max volume level only, when playing deep bass, still loud.
So I take it to service again and this time they made the top speaker very very quiet but the crackling was gone.
I asked them to fix it but they said it's always been like that.
After struggling for some 15 minutes they agreed to look into it. They tell me that they've replaced the top speaker module but the sound is still low.
I can even test the issue using the help app, hardware diagnostics.
Now I don't know how to get it fixed.

Water drop sound, normal?

Hi guys! I recently bought my Oneplus 5t. To make sure everything is okay I had a question.
My Oneplus 5t is working very well, I really like it a lot. I only discovered one thing. When using vibration when the speaker is on you hear besides from the normal vibration sound another very little sound. Now this sound is not that bad, and you might not even hear it. But i was wondering if this is a normal sound.
Fot instance when you unlock the phone. When unlocking you hear a little unlock sound. After this sound the speaker will be on for around 1 or 2 seconds. You'll hear almost nothing, but when placing your ear against the speaker you hear a little static sound. This is normal and on ervery phone, and goes away after a couple of seconds. This is because for your speaker to work you''l need some eletricity going trough it. Again, you almost don't hear this and it's very normal.
When this sound is on and you press for instance the home bottom. The phone will vibrate, if you do this a couple of times fast after unlocking, when the speaker is still on, you''ll hear that little sound I was talking about before. After a couple of seconds, when the speaker is compelety turned off, you don't hear the sound anymore when virbating.
So my conclusion is that it's probably the phone vibrating when the speaker is on, and this (due to how the phone is made) makes a little rosonance with the speaker. I knot for a fact that they moved the vibration motor on the 5t to the bottom off the phone, so it's next to the speaker. Again it's almost no sound and you'll only notice it if you're very carefull. I just wanted to check if my conclusion is right and there is no problem with the phone itself.
In the following video I demonstrate te problem. I will play some music and then let the phone vibrate. From second 2 to 5 you'll hear the 'water drop' sound. The speaker is now still on because it takes some time for the speaker to totaly 'rest' (again this is normal and on every single phone with a speaker). After second 5 the speaker turns totaly off however, and now you'll hear no more water drup sound.

I've also contacted Oneplus Support wirh the video. They said that their devices had it too and that it was a normal sound. What do you guys thinks?

In my eyes OnePlus has done some sh** with this. Same like the "upside down" screen in OnePlus5.
Edit: don't get me wrong. I love the 5T and I cannot think of using another smartphone. But I know oneplus and they will say:"It's normal behavior Blabla"

Thanks for the reply man!
I've seen both treads (made the OnePlus one myself haha). Also got answer from the technical support of OnePlus who analysed my video more times and told me they noticed the sound but it's normal and in their phones too.
I agree that they did not totally think this one through. The vibration motor is just to close to the speaker.. They should have put in the same location as the 5.
But well I guess it's just getting used to. Many people don't ever noticed it I guess, for instance, when you turn on 'sound on tap' you can't even hear it, and it sounds pretty normal if you don't know better.
I'm glad that it's not a hardware malfunction, but it's some getting used to. Further than that, it's an truly amazing phone..

It's your post on OnePlus? Haha didn't knew that
Yeah you're right, this phone is amazing. Hopefully we get used to it and we won't notice it anymore.
At first I thought it was an issue with only my phone. I was going crazy haha

Yeah same man.. I was afraid I had to get it in for repair..
I think many people don't realize it because it's so little? I mean when you do notice it and you're like us (worried if you're new phone might be broken) you'll know. But otherwise the sound is pretty normal I guess?
Glad that it's okay
