Noise/ Static when calling and Unsafe Electricity - JAM, MDA Compact, S100 General

From the beginning I keep hearing static in the background of calls, when calling with the MDA to my ear, and a sort of ticking noise, short clicks constantly repeated in the static. The ticking sounds electronic, like the ticking of electronic cycles. I don't hear it when someone is talking, but when there is a pause in the conversation, it is clearly audible for me, not for the other party. I don't hear it with the headset or handsfree on. It is not really bothering me now, but the possibility of a total break down in the future is. Has this to do with a faulty speaker, or do more people have this noise?
Furthermore a safety issue: This morning my Compact was connected to my desktop, syncing and charging. When I received a call I picked up the Compact and put it to my ear, keeping it connected to the USB cable. Within 30 secs I got two electronic shocks to my ear, after removing the Compact from the cable no further shocks happened. So be carefull to unhook your Magician first before answering a call! I think it has to do with the outside being metallic and therefore able to conduct electricity or something like that.

I suppose, that these short clicks appear beacause of the powerfull earphone.
For example, if i make a phone call with hi-fi speakers on, i'll hear the same clicks.

Earphone plugged in causes phone to end call

Hi
Wondering if this is a prob with the earphones or the xdaII unit
Can make calls etc fine. However, when i plug the standard earphones in and make a phone call, i get cut off about 3 seconds into the call. I can hear through both earphones. Tried fiddling with the socket, but nothing gives.
Fault in the audio connector?
I've had this happen, I've also had a call drop when I plug the unit in for charging.

No sound during call, however speakerphone & headset wor

I have the same problem:
No sound during call, however speakerphone works and headset works well. There is no sound only when I use it as regular phone. Person on the other line can hear me well all the time.
When I raise volume during call I can hear peices of the person on the other line, at the same time as phone beeps that it reached sound maximum.
This happened after phone was dropped and it hard reset itself automatically.
I am trying to reboot it now with different ROM.
Headset jack hasnothing to do with it, since speakerphone works well.
If anybody has any idea please share.
Thanks
This is a hardware issue, (the audio for the internal speaker and microphone is routed via the headphone socket) The socket has a very small switch that is opperated by physically inserting the jack plug. Sometime mine plays up and I fix it by pushing a straigtened out paperclip into the socket.

Big Thanks DOC C
This is the first time i post a reply even though i've been a member of xda-developers for a long time and like the work done here. I must say that I was about to throw my phone if it wasn't for DOC D. The problem is indeed with the headphone jack. Sound in my earphones is messed up and phone calls have no voice. You just saved me a few hundred bucks!! BIG HUG!

Did you use to carry your pone in your pocked? Sometimes there is a small peace of dust opening that small switch inside the headphone jack. Maybe you try to get rid of it with compressed air. In some cases the connection between that connector and the main-board is broken. Dismantling is a good idea, but you have to know, what you're doing. The fact that the headphone is working well, is a good sign, that the problem is inside that jack.
In some cases the springs that contact the speaker to the MB are worn or dusty, try to get a better connection.
sound problem in my smartphone hct tytn 2
Helo dear friends

Buzz from speakers

I bought a phone second hand. Was supposedly in good working order.
2 months in, the phone has developed an annoying buzz on the speakers when a call is in progress. It sounds like the usual buzz you would get if you held a phone next to unshielded speakers.
Is this common? Is there a good/known fix for this if I open the case?
Sound goes if a headset is plugged in, either wired or bluetooth.

In call microphone issues when using headphones

Does anyone else have the problem where the other person can't hear you when you use a pair of headphones while in a call? When removed, they can hear me fine. I'm hoping that this is a software issue that can be resolved in an update. If not, then i want to return it before my remorse period is over.
I am having distorted sound - other party hearing it unclear and distorted..
looks like a hardware issue.. tried with 2 earpiece... no luck.
I'm actually starting to wonder about that. It may actually be a software/driver issue. I was on the phone yesterday and decided to do some testing. Unplugging them and plugging them back in provides perfect audio to the other person for a few seconds before going back to garbage, as does muting and then un-muting the microphone when in a call. Something I've noticed about the microphone is that the gain seems to be set too high - try to make a recording of cars going by - guaranteed clipping (don't have the volume too loud or you could blow out the speaker you're listening to it on).

I ran into the same issue. However, the headphones I was using didn't have a built in microphone. I discovered that if I plug in headphones that lacked a built-in mic, the phone switches its internal microphone's gain to the gain it would use if you were holding the headset to your ear. I held the microphone in close proximity to my mouth and that solved the issue.
I guess this would be a software issue.

That's exactly the testing I did and exactly what I was thinking. Now to wait for LG or Google to fix it.
Another experiment you might try would be to put your finger over the secondary microphone on top of the phone and see if that makes a difference. (My guess is that the reason your voice comes through softly with the headphone plugged in is that the phone is still doing background noise suppression, which works by taking the difference between the main microphone, which picks up your voice plus ambient noise, and the secondary microphone, which mostly picks up just the ambient noise. When your mouth is far away from the phone, your voice is equally loud in both microphones, so the difference doesn't yield much voice signal. If your voice comes through louder after stopping up the secondary microphone, that would confirm this explanation for the problem.)

Next time I'm in a long phone call where I am using headphones, I'm going to try that. It could be possible.

This appears to be what is happening. The top mic is doing noise cancelation for the bottom mic.
I called a friend and plugged in headphones. When I didn't cover either mic, she said I was quiet (because the phone thought I was background noise). When I covered the top mic, she could hear me fine.
At this point, I'm inclined to say this is a software issue because the phone app can switch between microphones and which one is used for background noise cancelation. (Putting the device in speaker mode appears to use the top mic only.)

That's good confirmation -- thanks for running the experiment. Maybe I'll put a little wad of putty in the car to stick over the top microphone while I'm driving!

Odd, extremely faint sounds coming from inside of S4

So today I was in the living room with no one around or other noise, and was talking on the phone laying on my side and just having the phone lay on top of my ear. When the conversation stopped and the person on the other end hung up, I noticed that there was some very faint buzzing noises coming from what appears to be the inside of the phone.
I did some experimenting and found that when my phone is on, there is a buzzing/humming noise that's really only audible from the earpiece speaker. The closest thing I could compare the sound to is a hard drive reading or writing data. Right after turning the screen off, the buzzing/humming changes to a higher-pitched crackling that has alternations (like some computers where you plug headphones in and can hear buzzing whenever you move the mouse or do something). About 5-10 seconds with the screen of it turns to a solid high-frequency whine (like what you get with some USB wall charger bricks, but actually more comparable to something like the tire squeal of a car doing a burnout).
Has anybody ever witnessed this? These are quite high-frequency and VERY faint sounds so some people might have it but not be able to hear it with their ears themselves, but it's just something that I noticed.
I hear it too, it's so cool to hear the raw processes taking place within a microchip! Nothing like it at all.
