GSM interference in optimus 2x itself - LG Optimus 2x

Some people in the Netherlands are experiencing the optimus 2x is interfering with itself (buzzzzzzz sound) , but only when it's on 2G.
The annoying sound can be heard by the person you're calling with (!).
Hope this is a software problem that can be fixed.

RE:
I hope that that is few pieces issue. I am mostly on 2G in CzechRepublic. Situation is changing now, but there is no 3G at the place I live....
Ill refere when I get mine. I hope that it will be soon.

I've searched around and found this topic about an other phone, it was fixed by a software update: http://forum.xda-developers.com/showthread.php?t=384064
I hope that lg fixes this soon!

Maybe if you try to flash this baseband: http://forum.xda-developers.com/showthread.php?t=1082195&page=3
People are reporting a better call quality with this baseband. I'm about to try it too but i'm not experienced with flashing...

I have this problem when I listen to music while 2G is on. The interference is annoying.

Good news! baseband 502 solved this problem for me!
Call quality is much better with the 502 baseband.

Phonecalls keep cutting out during mid call.and people complain they cant hear me

Hi
Had the kaiser 3 months now..had the initial prob with the speaker phone...where people just couldnt hear me..now this..
I know its the phone has tried my chip in my old phone and no problems.
everytime I make a call the other people say that my voice is cutting out and coming back in..sometimes the phone call just cuts off and i have to call back..
anybody here having the same probs with Kaiser/wario III etc.??????

This could be a hardware, software issue. Without checking we cannot tell. Hopefully it's either software or the "banswitching" issue. If it is a new thing that has just started then a hard reset may solve the problem.
Many folks with newer phones in areas where different available phone bands are present, report dropped calls as the phone seeks to change to the strongest signal.
See this thread (one of many) that mentions the problem) also note the Bandswitch application that lets you fix the phone to one band to avoid the problem:

I presume you've tried turning off Microphone AGC (Automatic Gain Control) if it was enabled and you're using the speakerphone?

[Q] Low Microphone Call Quality & last firmware upgrade

Does anyone of you have experienced a low microphone volume/quality in call conversations?
People from the other side of the phone often tell me they cannot hear me... and this is quite
annoying.
I have read something about a noise cancellation problem. Have you the same problem? Any
SW solution to it? How did you manage it?
Thank you
Yeah, I also hear that often. It started happening after the Gingerbread update. It seems HTC decreased the mic sensitivity to fix the echo problem but they probably went a bit too far.
I just got the 2.30.405.1 OTA update 30 mins ago. Let's hope they've fixed this issue and also the wifi sensitivity problem.
Is it a new gingerbread upgrade? I have not received any notification yet!

Nope, it's just a HTC bug fix update. Still waiting for the Gingerbread 2.3.4. According to first comments I've seen the wifi sensitivity problem has now been fixed!
Try the manual update check, that's what I did. If you don't see any updates yet, you'll just have to wait a bit more until HTC's delivery system reaches your region/phone serial number.
I tried the manual update, but the upgrade is still not available. No matter, I'll wait. Happy about wi-fi! Any news about the Mic sensitivity?

Not yet on my part. I've answered three calls today and there were no mic problems, but I've gotten used to the problem, so I always try to position the phone so that the mic is close to my mouth. I'll try to be less careful in the future
I'm also happy to report that the infamous Dialer process has disappeared from the battery usage list, so that problem has been fixed. Dialer was almost always number 2 right after the display on my list. Now it's completely gone!
Mmm, very strange and too bad here in Italy, or better to me, no upgrade is notified or manually reachable yet! Kind of sure anyway the microphone problem will still be present. I haven't read anything on blogs about this type of improvement by the new firmware....

Still not available. How this is even possible?

Solved the firmware upgrade problem this way (thanks to HTC
customer service):
*#*#682#*#*
No big change about call quality...
At the moment I'm trying this:
after using the number *#*#4636#*#*, changed
network settings from WSCDM preferred to gsm auto prl
But I've just did this and not sure the problem is gone.
Just to let you know, the phone call is still bad.
I'm from Italy, but the phone was bought on Amazon.co.uk.
My phone model number is S710e, android 2.3.3., firmware is
2.30.405.1, radio module is 20.2808.30.085AU_3805.06.03.03_M
I have these problems for the radio module:
My voice is kind of intermittent from the other side of the phone (who listens me)
I can hear echo of my voice
The other side of the phone can hear its own echo
Sometimes connection is lost
Long time for the call to start
I have tried soft reset, updated firmware, set GSM auto (PRL) as network preference, etc.
No solution? I'm thinking of flashing ROM, radio module and whatever... but if the phone is broken, what about warranty loss?
I don't think there's much to do at the moment. Nothing seems to work. All we can do is wait for the 2.3.4 upgrade and hope that it includes also HTC's own firmware tweaks, especially for the abysmal radio module.
I believe they can further adjust the mic/noise cancellation sensitivity and hopefully solve the issue where people on the other end are constantly complaining about disappearing sound.
I'm pretty sure the radio antenna in the back cover is total crap and obviously can't be fixed with software upgrades. A revised back cover with a better antenna would be nice but I doubt it will ever happen, sigh. I'm sick and tired of having to end calls because people are complaining about intolerable echoing on their end. This can happen, if the signal level is even one bar below full.
My friend got Incredible S and he is having the same issue...
Whenever he calls me his volume is too low despite the fact my call volume is full...
He was concerned about it and today I searched for this issue on google and got directed here.
Is this software issue or hardware?
He got 2.3.3 pre installed..
I really don't know if it's a hardware or software problem.
Since I've read someone never experienced the problem,
it could be hardware.
But, many people who sent back the phone to customer
center, after hardware repair, tell to have the problem, still.
So it could be a software problem, caused by HTC SW
radio module. In this sense, it would be nice to know if
those one who had this problem and rooted their phone
to another UI (cyanogenmod, etc.), or changed
the radio module, were able to solve this problem. In this
case it would be definitely a SW problem.
Really, I don't know what to do... I cannot root my phone
because of the warranty, there is no official good SW solution
and I am not sure if the problem is SW.
Why should I stay with a broken phone, but a good smart
device? People, let's think about that.
We should complain with HTC...
Only 2 members with this issue alarms me of hardware issue... U r lucky to have warranty but my friend's mobile has none.. It would be a shock for him of out turns out hardware issue...
I tried rooting his mobile but Alpharevx didn't work for him and I was not willing, to flash european rom...
I guess I have no choice other than to root it and flash a different radio. .
Will try after a couple of weeks when he comes...
That's bad.
Waiting for news about your flashing the device.
For the moment I have to wait, so I will not send back my
phone.
I'm leaving for holidays and I need to use my device as GPS
navigator...

no news, i am facing same problems with the mic even after latest update
On another support forum (http://androidforums.com/htc-incredible-s/374601-call-problem-echo-other-end.html),
other users noticed the same problem and told me this problem is particularly frequent with Vodafone networks and specific numbers.
I experimented the problem too with Vodafone mobile operator and now I'm trying with Wind. Conversations seem to be better, but I'm still in the testing phase.
What about you? Do you have Vodafone too?
Let me know.

Hey ! that sounds much true. Infact my Friend's mobile had this Low volume Prob I mentioned previously but yesterday he called me and the sound was fine from his side. Infact he changed his network 2 weeks back. I guess it has problem with some networks...
It's a HTC thing.
All HTC phones have bad microphones, crappy speakers and use codecs from the '90s.

echoes on call

when i call somebody sometimes it does happen to hear my own voice upon the call is happening very often and i am getting annoyed by it ,is it cause i have it on 2g network ,also it is rooted with monxfied rom but it did happen sometimes and with original rom
phone is c6903
any solution recommended i will hear
Sometime happen to me too. It can be for some reason, speaker on of the phone the one who you calling or delay between the 2 phones so practically when you voice reach the other one you can hear a kind of echo. It's not a software related or even to the phone. I know it can be annoying so maybe you can improve the quality call on your phone settings, there can be some.

i have same issue and it happens quite often.
It's not 2G problem because it happens regardless on 3G, H+ or 4G LTE,
only way to solve that is to use headsets or reboot the device.
FYI, mine is unrooted, original rom/kernel and C6906

Lollipop Mic problem

After updating to lollipop 270 people tell me that they have hard time understanding what I say in voice calls. The microphone test is OK but I still have problems. I tried to turn off the noise suppression but no effect. Anyone else with this problem?
I too have had this problem, although I am not sure if what I have done is a solution, but so far its working fine. Anyway what I have found is that if I go into Settings>More>Mobile Networks>Network Operators for some reason I had been lowered to a 2G network instead of 3G or 4G. This worked for me so far however as I said I am not sure if it is a solution.

It is not that for me because I have full signal strength and I did a test on 2 and 3g and the problem persist.

Same here bro. In initial lollipop build the call quality was OK but now I barely can talk. Hope that Sony will fix it in next update
Same for me. People telling me that they cannot udnerstand me when calling.
I tried once to switch from 4G to 3G and then the person I called understood me. I will have to verify if this is maybe a work-around.
I did the Microphone check and it seems to work. I assume it is not a microphone issue. It seems to be some kind of (gsm) voice call transfering thing...
Anyway.. I enver had this problem before (on KitKat)...
Edit:
I just checked the Sony support forum.
There is a work-around for this that says disabling noice cancellation and other sound enhancements as well as setting the equalizer to normal can fix the problem.
Also Switching back to WCDMA only helped some people...

+1 . Setting it on wcdma resolves the problem but that is a temp fix because not in all places i have that covere. Hope Sony will fix it in next update.

Nexus 6 32gb calling issue

Hi, I am new here if I am in the incorrect thread or the issue has been mentioned really appreciated to know the link.
I just got a Nexus 6 (new) everything is working fine until I did a call. I would hear a lot of static and crackling. Sometimes it would stop, but it would come back. I know it shouldn't be my network since I upgraded from a Motorola X 2013 model and didn't have this issue. The newest OS I am running on is the 5.1.1 android. I know its not the speakers since I watched a video and that didnt show the issue. Its basically via phone calls. I am running on the T-Mobile network. Would this be a hardware issue, software issue? I am concern since I just got the phone if their is a fix really appreciate it.

well, it very well could be your local network. try a different tmobile apn, thats all i could recommend. the moto x is a different phone, and you probably were using a different apn.

Sometimes when you are in between two lte towers they can conflict and call quality can significantly drop (in also might be local t-mobile issue).
The easy fix is to go to Settings --> More --> Cellular networks --> switch off VoLTE
It does put phone in HSPA connection mode, but for most part it's good, if you don't watch videos...
I believe it's the whole volte (as mentioned by monster Mary) I lowered it to 3g and I did a call not a single static will update if their is still issues thanks for the helpful feedbacks guys.
