Bad call quality and metalic distortions - Galaxy S 4 Q&A, Help & Troubleshooting

Hello friends!
I'm experiencing metalic distortions (like robotic metalic sound when in call) and general bad call quality in miui v7 (4.4.2)
I flashed over stock lollipop i9500 5.0.1 which has i9500xxuhpc1 baseband...
I have searched for answer but no luck
I have also tried to flash different modems from the modem thread both from odin and recovery, but all of them result in no reception..
I live in Israel and my carrier is cellcom...
Really would appreciate help as I love this rom a lot!

Could it be that your ear-piece is just broken?

Hi unfortunately the problem only occurs with miui rom and not on neither cyanogen or stock..
Thank you for replying

Then it's definitely something on the ROM side. Did you look through the ROM thread to see if there is any fix?

Similar responses were in the thread, most were said to be fixed by replacing modem, which i tried to do with many different ones including ripping from modems of local stock roms from sammobile
But all result in either no bars or same bad call quality

Does the ROM have any sound mods that could be messing with the call quality?

I believe it has some sort of sound mod ( atleast it enables you to choose custom preset for like viper4android ) but other person in call is also hearing the metalic distortions so i assume it affects the microphone and not just the audio, so i dont think its the sound mod.

external phone speaker fixed ?

Has anyone hacked the kernel, hardware to make this phone useable.......I'm missing so many calls ?
There is no hardware or software issue with the speakers ...... maybe you have a faulty device.

In your alternate universe that may be true. That's the universe where the battery is brilliant too, I presume?
vxnice said:
No need to bring in the word homosexuality when we are talking about external speaker on the phone androhero...thousands of people complain about the speaker and battery life its even be said in a lot of reviews all over the web about the speaker and battery life....if your speaker is perfect that's great. But my speaker isn't and I just want to see if anyone have fixed this problem so please we can do with out the smart ass comments..

for starters , i wasnt the one that started making sarcastic comments, all i said was there is no hardware or software issue with the DHD regarding the speakers, its just the way the HTC Tones are made, but if you feel you wish to join in and attempt to bully me like bobbyelliott feel free
by the way you may also want to try this, it's the htc tones with increased volume levels, just flash it from recovery...... i hope you choke on it

Ok, I don't want to see any trouble here. Please behave yourselves. Referrence to homosexuality as an insult is not appreciated.
Leedroid has posted a kernel that increases speaker volume by 20%, he is posting a new update tonight 2.0.5.

The Android Revolution Rom 2.0.12 has this included since yesterday.
do you just flash these kernels using clockwork overtop the rom your already using?
ive never done this before and would like more volume myself.

Hi can you please give me step by step on how to install the new kernel ? Thanks
Is it really nessesary to flash and what not? I just bumped up the volume of the tones I like in Audacity and copied it back on to SD. Now my volume is “normal”.

Without a kernel that gives a volume boost I find most of the times myself in a situation where I can't hear the person when on a call. With the new kernel (thanks Lee ) it's how it should be, I'm happy

[Q] Nexus 4 front speaker issues

Hello,
This is my first post so sorry if something is done wrong or whatever. Ive been having issues with my front speaker. I dont think i did anything to break it (i drink a lot though) but its been completely useless for the past week or two. I have the latest cm 10.2 and franco kernel nightlies. I thought updating them might help but it didnt. I also can no longer talk to people on speakerphone like i could before (while the speaker still didnt work). I also tried headphones and now they dont with either. Does anyone have any idea what it could be and/or different ways to fix the speaker?
Thanks in advanced!

Video Audio Concerts Distorted

When recording in loud situations for example me and my friend we got the very same phone S Galaxy Note 3, went to this EDM concert and we both took a couple of videos, hes got original stock rom and i have rooted custom rom, his recording was really good on the bass audio but mine was unbearable on the sound it was really distorted all the way through when the bass comes, and i have tried a couple of roms now but with the same outcome, so i was just wondering what could be causing this, and how to fix this...? Thanks in advance..!

Cyanogenmod - Bottom mic not working on any version?

Hey guys, recently just picked up an S4 from a friend after my HTC One battery kicked it. I have a random problem with the phone that I'm hoping someone here can help with.
When using a stock or TouchWiz ROM, I have zero problems with both the top and bottom microphones. I can speak to people in calls or record voice using apps and it's loud and clear. When I install a Cyanogenmod of any version (I have tried 10, 11, 12, 12.1, and 13) the bottom mic drops it and becomes very muffled to the point where you can't hear anything on the other end or in a recording. Speaking in to the top mic works perfectly though. Bluetooth works fine too and I have no issue speaking to or using A2DP with it.
Has anyone seen this before, and if so, has anyone fixed this? I'd much rather use a Cyanogenmod ROM instead of TouchWiz but at the moment it seems I have no choice ...
Try other roms. CM based or AOSP roms.

I've tried a few other CM roms, I'll find an AOSP rom and give it a go now!
EDIT: Just tried two AOSP roms, same deal. Top mic is loud, bottom mic is quiet ... No good!
I'm running CM13 without issues.

Try a rom that has alucard kernel (either flash optimized cm12.1 or jdc team aosp) and go into stweaks and in the sound tab change the microphone gain sliders.

Tried CM13, same issue carries on.
I now have CM12.1 with Alucard kernel and STweaks. I've turned the Camera Mic Gain up to 60 and people can hear me now, but they say it sounds slightly quiet still. Is there anyway to go past the max setting in the STweaks?
Not that I know of.

Are you sure you don't got dust in the two holes? Sound to me you have to clean the two holes.
Nope, I had the phone apart and cleaned both holes, no difference.
The confusing part is that on a TouchWiz ROM the microphones work as they should. It's not until I'm running CM or AOSP that I get this problem.
It's almost as if the microphones have been switched and the top becomes the voice mic and the bottom becomes the noise cancelling one.

I've lost count of how many times I've pointed out this problem. No, changing gain value will not solve the problem. This has been a truly dealbreaker for me, as this affects every cm based rom. @AntaresOne said that this problem comes from using caf drivers and I think it cannot be fixed unless Samsung releases its own source codes.

It's strange because on my I9505 I never experienced this problem.
What bootloader and modem are you running?

Well that is crap ... I guess I'll have to go back to TouchWiz which is a damn shame. Have you had any success with AOSP ROMs?

They are all in the same boat. To solve all problems you have to stay with TouchWiz ROMs

It's not that hard to believe, seeing as there are over 40 different S4 models. You just can't make a rom to work perfectly on all.
I never had any major problems with any of the roms I flashed, yet other people seemed to have serious issues with the same rom.
I don't know why Samsung can't make just one model. It splits the user base, it gives them more headaches because of updates and such.

Yes, I agree on that. It's crazy to make that many models. I made the assumption that he has an i9505 but maybe he has a different model.
Try to record a voice message with Whatsapp using TW/GE rom and then with CM/AOSP rom, you will clearly hear the difference. jfltexx here.

Yes, I've tried AOSP roms but no differences. AOSP based roms for S4 share some sources with CM.

Bootloader/baseband is I9505XXUGNG2
Going to try updating to the latest baseband soon and see if that has any effect.
Pain in the ass but see how we go!
