Hi,
Sony Xperia z2 D6503.
Bootloader: Unlocked.
Root: NOT rooted.
The device has a microphone issue. When talking on headset (not speaker) the other side hardly hears a word / does not hear at all. When phone is supported by the shoulder, the other side says the voice is "broken" (if he manages to hear).
This issue was for quite some time, only now the phone came to me. It is a phone who the owner purchased as a "Grade A used phone". The phone has no warranty.
The past few month, the phone had 23.1.A.0.726 (UK version).
Yestorday:
I've flashed via "emma tool" 23.1.A.1.28 - Microphone issue is still there.
I've flashed via "FlashTool" 23.4.A.1.264 (UK version) - Microphone issue is still there.
[Yes, Iv'e tried the "Noice Cancelling Suppression" option]
I am not sure how to root the phone because bootlader is unlocked. There is no data on the phone, so I don't care for any data loss.
I still hope there will be a way to solve the issue via software like suggested in this thread or here.
Or, a different solution, to flash eXistenZ ROM, mentioned here.
The day-today user os the phone is a ~24 old female. She is a simple user. Calls, tests, plays a few games, IM etc. Nothing special. She loves the battery life and the camera of the device. I believe that she does not really care if the Android version is 4.2 / 4.4 / 5.0.x / 5.1 / 6.x. As long as the device will work properly, she'll be grateful.
I am open to any idea, hopefully, will not need to by a replacement part (I will disassemble the phone myself, but, need to make sure what part I should purchase).
I am aware I am quite a newbie in the Android world. I have flashed many ROOMs on different devices. Used several times flashtool / adb commands (via a PC). But, I have a lot to learn and know I'll have a learning curve with the Xperia Z2.
I would love any input and guidance on how to root the phone. I don't care to downgrade to any version if it is necessary. The eXistenZ ROM is 4.4.x KitKat based on Stock 4.4.4 23.0.1.A.0.167.
How does one downgrade from 5.1 to 4.4? Should I flash the stock *.ftf 4.4 via FlashTool?
Hope the post is clear. Sorry for my English....
Thanks!
Have you tried setting microphone gain to high? Otherwise it's a hardware issue, or your microphone is blocked with dirt...
Sent from my D6503 using XDA-Developers mobile app
Tnx for your reply.
Where do I change the microphone gain? Tried googling it, but, no success.
The past few hours, I finally managed to flash eXistenZ ROM (after soft bricking the phone and other fun stuff).
The phone is rooted now (with eXistenZ ROM).
The past few days I googled and googled. Read a lot, but... still stuck :/
The mic issue seems to be a little bit better, but, far from ideal.
I have no idea what are the optimized settings with this ROM.
If any member has this ROM due to the mic issue, I would love some advice.
Feeling like I'm grasping at straws.
~~~~~
As for hardware issue -
1. My understanding is that the mic is located on the bottom-base of the phone (not under the screen).
2. What do you mean by dirt? should I disassemble the phone and clean it out? (I don't care to open it myself. I have a history of replacing phone parts. I'm not a professional, but, find my way... [a few iPhones, Nexus 5, a few Samsung devices and more).
3. If I'll need to replace the microphone, I'll purchase the part from AliExpress (I don't live in Europe or North America). I am not sure if this part or maybe this.
False alarm... My bad, I thought you didn't try the noise suppression trick.

The last half year have riddled various forums with the now infamous Samsung HW/SW bug that is most often causing an extremely unpleasant echo in the other end of a conversation. However, this bug appears in many variants due to the multiple causes of many interacting smaller problems.
In my own quest of finding the root of the problem and scanning the web for a potential solution (not involving send my phone off), I decided to share my findings, very well aware of the shortcomings of my limited research. So please let me know of any current (or future) solution to this, or if I have missed anything important.
Internally there are 2 microphones and 2 speakers. Unfortunately the way these are situated, aligned and and isolated, together with the sound transmission throughout the phone chassis and the complicated sound and digital noise reduction (NR) settings, are the cause of these problems.
All this can best be seen in the iFixit's teardown guide:
http://www.ifixit.com/Teardown/Samsung-Galaxy-S-II-Teardown/5861/1
or in the "S2 screen replacement photo tutorial":
http://forum.xda-developers.com/showthread.php?t=1253969
or in the schematic blow-apart diagram in the official "Samsung-GT-i9100-service-manual". (Google that!)
My Conclusion:
After performing a limited number of tests, on my own, I have concluded that this problem should in ANY case be resolvable by a fix in the phone firmware/software. Obviously the phone is working without a case, and (usually) perfectly when turning off NR (noise reduction) and/or turning down the volume. Others report fiddling with the internal rubber enclosure of the microphones and/or speakers. In either case, it would be very interesting to know the details of your phone's SW and HW configuration as many reports differences in behavior after flashing new/old phone software. It is very likely the problem occurs as a combination of "PHONE/PDA" software, the lower USB charge-port HW and the upper speaker/microphone insulation. In other words the NR algorithm need to be changed or better tuned for various environments. We can only hope Samsung fixes this in their next updates... But very unlikely as they are much more interested in making new phones and selling more of them. And if they did fix it, they probably wouldn't tell anyone since if they ever did admit to any wrong doing, they'd have to replace/repair probably at least tens of thousands of phones!
Problem (Simple Description):
A number of small assembly line variations is causing the internal noise reduction software to misbehave. (Remember the "butterfly effect"!)
Problem (Technical Description):
The problem consists of (at least) 3 smaller problems working together.
1. The lower playback speaker is always on (!) and is causing feedback to the lower microphone when using a protective cover. Thus explaining the greater echo at higher volumes and less external noise, when using a rubber cover.
2. The SGS2 plastic casing transmits sound around the entire phone. Thus both speakers (lower and upper) are transmitting sound to both the lower normal microphone and the upper noise cancelling microphone. These need to be isolated.
So when covering the upper noise reduction microphone you are getting better feedback (more "noise") from both upper AND lower speakers, than from outside and thus (usually) improving call quality by reducing the echo effect, but when there is no case-cover and a noisy environment, you may end up increasing the echo, by covering it up!
3. BUT not all phones have echo, thus there is also a NR settings or algorithm problem that should or may be resolved by a firmware/phone/PDA update. In addition, and making things even more complicated, different phones have slightly different hardware on the PCB of the USB charge-port...
Who to Blame?
1. Samsung Hardware engineers who must have been sleeping in their "Acoustics and Wave Propagation" classes.
2. Samsung (?) Software engineers who never took a course in "Feedback and Control Theory".
3. Samsung HW design director(s) who
a) didn't make (1) and (2) work closely enough together on the SGS-2.
b) never though of putting a rubber case on the phone! 4. Samsung Assembly line Quality Control manager(s) who didn't check for minor design flaws.
- check (open up) every 100 or so phones, if problem check ALL previous 100 and estimate problem!
- stop assembly line and talk to the management about solution ..
..
oo. The casual SGS2 owner who just wanted to protect his new investment with a rubber/plastic cover.

3. Attach layers of soft electrically and noise insulating tape (e.g. medical-tape) over the back-side of the upper speaker, earphone jack and microphone. On the inside of you phone. See instructions in Hebrew (!) below:
http://iandroid.co.il/forum/topic56552.html
DIY Home Fixes (various success):
4. Put some tape over the top NR hole, which is next to the 3.5mm head-phone jack. (This fix messes up the speakerphone functionality!)
5. Put some tape over the hole just above volume-rocker
6. Lower volume
7. Manually disable NR during call: ("HOME" button)
8. Factory Reset (This will wipe your data/contacts and probably only lasts until next reboot!)
9. Try to flash a different phone ROM/Firmware/Kernel/Baseband etc. (Seem like it's mostly Gingerbread 2.3.4 phones being affected.)
10. Perhaps by changing some settings in the hidden "Service Mode" menus (???)
11. Open your phone and
a) make the bottom small microphone hole in the case bigger and
b) cut some of the rubber from the lower microphone cover.

Apparently there are other ways in which you can directly hack the Phone.apk package, under certain conditions. Thus at least in theory it should be possible to directly toggle NR in memory, which could indeed be useful. Here is one variation of the APK hack:
In the Phone.apk package, find the ../res/values/bools.xml file. Edit and recompile after changing the line: "<bool name="has_in_call_noise_suppression">true</bool>".

UPDATE: 2012-01-30
Apparently there have been many reports of very happy people doing their own SGS2 surgery following the thread:
http://forum.xda-developers.com/showthread.php?t=1441510
This is essentially equivalent to the solution in number #3 above!
+1 for the effort, about time someone did an all-in-one topic about this rather common issue.
I've had the same problem and noticed it the day I bought my phone, a friend called and immediately complained about the echo. I did a quick Google search and found out that it's a rather common problem and caused by most case types, removing the case or disabling NR did indeed fix my problem.
Anyway, I have tried many fixes, including VillianTweaks/LeoMar's fix, turns out those only remove the ability to turn NR on/off, but it was still turned on by default. This fix however was the only one that actually worked:
http://forum.xda-developers.com/showthread.php?t=1332137
The fix above had a minor drawback though, the first call after reboot always had NR enabled by default. I wanted a set and forget solution to permanently disable NR so I learned a bit about deodexing/decompiling and managed to get rid of it for good, you can check the fix in here:

I'd disagree. I heard a slight echo also without the case (I called from a land phone to hear it myself). Lots of SGS2s work fine with cases, with NR on. Killing NR should not be considered the solution.
I've opened the phone and inserted two thin layers of white medical tape over the ear speaker (much less tape than in that hebrew sample). The original echo gone completely, with and without case. But now the other party hears a very slight echo of me. I don't consider tape a solution either. Perhaps the speaker is not mounted properly (sticks out too much)?
I was wondering about the position of the cushion, don't understand what that guy meant precisely. Mine looked a bit squashed by the case, maybe too firm contact?
> 1. The lower playback speaker is always on (!)
Are you sure? It could be transmission via the case? I guess the add-on cases increase the transmission.
> 3. BUT not all phones have echo, thus there is also a NR settings or algorithm problem that should or may be resolved by a firmware/phone/PDA update.
I'm not sure the NR algorithm can be fixed so that it can work with a faulty phone.

@bazzag: Thanks for VillainTweaks info, I'll scratch that until further notice.
@_sem_: Essentially I agree that killing NR is not a proper solution, as it is just a remedy for a sickness, which would return in a very noisy environment when NR may be needed. But given that this will probably never get properly fixed, it seem to be the best option we have for now. ALSO:
a) In the 1st § you say you called your own phone and found echo, then in the 2nd § you said: "But now the other party hears a very slight echo of me." these seem the same to me, or did you mean that now you hear echo when using your mobile to call someone else?
b) > 1. The lower playback speaker is always on (!)
Actually I am not sure about this as I live in very noisy environment, but everyone standing next to me, during phone calls, say then can hear everything the other person is saying!
c) > Service Center Solutions: Add 4. Replace old SIM card
Now THIS is a shocker! Why on earth would upgrading the SIM card have anything to do with this? Where did you see and hear about this solution?

I think the best option is the service center if you have stock ROM. You may need to convince them first, best by showing another SGS2 that works fine with your case. But that'd take much more time for me than inserting that tape did.
It really isn't difficult. Except that I'd feel a bit better knowing the exact problem better. It may be possible that the change was just due to taking the phone apart and back, not the due to the tape. I'm too lazy to do it five times trying this and that I'd ask the next one who tries this to check if the speaker can perhaps be pushed a fraction of a mm deeper into its seat, so that the speaker would have less or no contact with the (removed) back of the case. I think this could be better than tape.
> a) In the 1st § you say you called your own phone and found echo, then in the 2nd § you said: "But now the other party hears a very slight echo of me." these seem the same to me, or did you mean that now you hear echo when using your mobile to call someone else?
This echo is on the level of the previous echo without case - barely noticable if you're listening carefully, but no longer an issue really. And, those phones that do not have the problem don't have any tape inside
b) > 1. The lower playback speaker is always on (!)
> Actually I am not sure about this as I live in very noisy environment, but everyone standing next to me, during phone calls, say then can hear everything the other person is saying!
I think this could also be caused by the case conducting the sound. It must also be emitting some around. I've also read some folks got improvements by cutting ugly large holes in gel cases at the back - that'd probably decrease conduction.

Just tried to install the zip on power up of the phone....it starts but I just get a signature verification failed error. The progress bar hangs and when I go back to the root menu in recovery the error message is present in red.
Am I doing something wrong?
I had also the echo problem and also the other person could not hear me well... After changing my modem firmware to BOKJ1. This is a custom made firmware for Greece Cosmote... My voice is now loud and clear.
But I have also made a change to the stock dialer at KK5 deodexed ROM (Omega v9) so that the phone starts with noise reduction off.. but you can enable it from the menu during call.

Hmmmmphh....back to a service centre for my phone then! This is a fundamental flaw with the phone. Problem still occurs without a case if the top of the phone moves too close to my head!
I'm very keen to get rid of the charging LED. (I don't want any LED at any time, but everything except charging can of course be switched off under Settings).
I've tried several apps, but all either require root or simply don't work.
My phone is not rooted and I don't want to root.
Does anyone know of any of the many LED-killing apps that actually work on the Ultra, without root? Many thanks.
I do not think such hardware function can be controlled without root access.
I've had to resoprt to sticking a tiny piece of gaffer tape over the LED!! Moreover I don't expect it to last more than a day.
Surely there must be a more elegant solution than that? Anyone ... ?

never going to happen on an unrooted device - the only way that this is possable is either a modified driver or seeing if there is a sys/ interface for the LED while on charge
Thanks. I'm fairly new to rooting, so please forgive if this is a naive question; but is it possible to get root access on the device in order to fix the LED issue (and also boost the appalling sound) and yet continue to run the stock ROM and go on receiving official Sony over-the-air updates?

Yes running with root will allow you to edit the mixer path xml file to get better sound, and you can still run 'Stock' just fine. OTAs may or may not work, seems to be about 70/30. It just depends what files the OTA script looks at.
Okay guys, this entire month I have been considering getting rid of my G2. Will try to keep the story short.
About 4 months ago, I sent my G2 (D802) to repair center. Issue was: at times, people could not hear me during calls. They ended up giving me a completely new G2 few months ago. This week alone, I have experienced at least 5 times where people could not hear me. Only workaround when this happens is to turn on speakers (however, everyone next to you will hear the conversation which it is not exactly great).
Getting sick of it. Calls. I repeat, CALLS I can not even make properly with this phone. Everytime I pick up the phone/call someone, I have to wonder if they will be able to hear me.
Currently I am on completely stock unrooted 20H KitKat, I have tried lollipop firmware but the issue remains. Happened on KitKat 20D too. There's a chance the issue is not on Jelly Bean but I have not tested that because I don't really want to be on JB.
I assume I am not the only one on this boat seeing as the issue is reported by a lot. Share thoughts, possible solutions, etc.
@eepyikes @vPro97 join the discussion.
What kind of cover do you use?

Nah. Changed provider about two months ago. Same same.
I have an issue when people are not able to hear me, and it always happens if i want my hands to be free and phone is held between my ears and shoulders(Maybe some issue with noise cancelling or misaligned microphone). Otherwise it just works fine.

and to be honest because of this i hope CM doesn't get the 2nd mic working. lol
It's the Google now detection, open Google now, goto settings and turn off From any screen
Maybe there is some dust or some other stuff in the small holes where the mic is which is making your voice more quiet or almost completely mutes the sound you are trying to record.
You should try and DISABLE Voice enhancement at Settings>Networks>Call..
it helped my whatsapp voice messages to be played clearly
Have had 5 G2s for different reasons and never ran into a Mic problem.
Have even used various Roms from stock JB to KK to Optimus G3.
Am on Tmobile and used nothing but D801s.
All have been white.
Not sure if that helps
There's hope for you if you're able to sell and replace your phone with another used G2 in mint condition
My experience is, once you've done a repair and things look botched, change the phone.

Have you tried increasing the volume of the mic by editing the mixer_paths.xml.

I had the same problem after i've bought my G2 last year. Even asked in offical german LG forum but got no answer.
Solution for me was flashing custom kernel (dorimanx). Since that time i've alway been on custom rom (stock and aosp) and never had that problem again.
Wich rev do you have?
Greetings everyone,
I had bought a Redmi Note 3 a couple months back. The microphone was perfectly fine at that time. After the MIUI 8 update, I am having a lot of issues with the microphone. When I call someone or vice-versa, I can hear them but they cannot hear me. People complaint that all they hear is static. When I restart my phone it starts working again for half to an hour. I even used the sound recorder but all I heard was pure static. A tap on the microphone gets it started everytime. I tried CIT and it doesn't work until I tap on the microphone. The tap isn't too hard nor too light. I thought the problem was with the MIUI8 and unlocked bootloader and flashed CyanogenMod 13 to see if it gets fixed. Now I hear static plus a little of my voice. When I shout right near the microphone, I can hear my voice but very lightly, along with lots of static. Is this a hardware or a software issue. And can someone tell me any way to fix it?:crying:
Edit: Just noticed that even though I can hear a faint sound of mine in sound recorder when I shout into the microphone, during calls people can't hear me. All they hear is static.
Thank you
Regards,
Sriram
Device: Redmi Note 3
Bootloader Status: Unlocked
Firmware: CyanogenMod 13
well, easiest step would be to go totally stock ... normal MIUI without anything fancy.
if the problem persists -> hardware issue
if problem is solved -> software issue

Thank you very much for replying. Although, I have already tried that. I went to cyanogenmod, then back to MIUI and then I even downgraded to check if the problem is there, after which I came back to cyanogenmod. The problem is always there. Its happening to a lot of redmi note 3 phones. Also, when I record audio I am able to hear my voice, but its very faint. There is a lot of static cutting it. Also, I had unlocked bootloader the unofficial way and had rooted it too. I did it the unofficial way because after I got permission from MIUI to unlock bootloader, the software to do that was constantly giving an error and was stuck at 50%. So due to this reason will my warranty get void or it will be good? And should I take the phone to the service center with cyanogenmod or MIUI and lock the bootloader and unroot it?
so youve been at the original stock software and the problem was still there?
then i believe its hardware related.
as you hear a bit of a sound ... maybe something blocks the microphone? ive watched severall dissasembly videos and it seems to be easy to take the back housing apart. i would do that, check if the microphone seems to be fine and test audio with the back housing apart.
in case you want to go to a service center i can only say what i would do.
i would get the phone as stock as it could be ...

Yes I was at stock and it was there. And I don't think I can remove the back housing part as doing that on redmi note 3 voids warranty and they charge you money for it and return the phone without any repair lol.
Anyways thank you very much. I will put it back to stock rom, relock the bootloader, bring back the old recovery and remove root and take it to the service center. Thank you for taking your time to reply. I really appreciate it.
Hi all, I have a Mate 10 Pro coming to replace my Galaxy Note 3.
It sounds like I might be able to get the Pro working the way I want it to without root, which would be fine I guess. On the other hand I really prefer to be able to do whatever I want with my stuff. Before I wipe out my warranty by unlocking the bootloader, I will use the phone for a while and watch out for any issues that would mean I needed the warranty.
Any suggestions on faults that are known to be relatively common with this device? I have been reading around and the only thing that really stands out so far is a bluetooth audio bug, which sounds like a software issue anyway (not very acceptable either by the sound of it.)
