Callers unable to hear my voice, seems muted or broken - Samsung Galaxy S7 Questions and Answers

Hi Guys,
Have had my S7 SM - G930FD (dual sim) for a little less then a month but have run into a major issue.
The caller is unable to me during phone calls. Have tested with the head set and on speaker phone and these seem to be working, although with speaker does seem to have echo. Also during normal call, I can hear myself on the S7.
Phone was a grey import from EBAY, country of origin is UAE and I am based in Sydney, Australia. I haven't changed any of the stock software. Its running on 6.0.1.
Have already tried factory reset.
Anyone has run into this issue? Haven't found topic regarding this issue. Or any ideas for solutions or if it could be hardware or software issue? Have never dropped the phone and has only briefly been in contact with water.

I think if you try to flash stock rom it could fix the issue, if not id say it is a hardware issue rather then software so id recommend you to take it into Samsung to get it checked or even replaced as it could be faulty
If you are willing to reflash stock rom onto your S7 here is the website that you can get the correct file http://www.sammobile.com/firmwares/ just insure that you put in the correct model number when searching

[Q]Please Help! Microphone not working on incoming calls..

Hello, i need some serious help over here
What's the problem:
I own a galaxy 3 since June, a week ago i started noticing the internal mic wasn't working on some incoming calls.
Details:
First of all the problem began for no apparent reason (the phone works fine otherwise and no major updates / new apps were installed)
This started happening on the official froyo ROM which was an excuse for me to flash the Kyrillos 9.4 ROM (wiped all data / formatted sd card in the process). The problem still occurs on Kyrillos 9.4 ROM suggesting that this is not a ROM issue
I thought it was a hardware issue but the caller can hear me perfectly if i connect the headset or use the speaker Also the internal mic works fine on some incoming calls and ALL outgoing ones!
Upon further investigation i came upon 2 threads on other forums (unfortunately i can't post the urls as i am a new user, if needed pm me or search google for "Microphone not working on incoming calls") which point out that the same problem incurs on HTCs and XPERIAs. Also it happens on replacement phones (original unit shipped back after this problem), on different providers, on official and custom ROMs, on clean phones (only the stock apps installed).
This seems to happen when the phone is idle for a set period of time (unconfirmed). Fast Reboot app / manual reboot / removing battery don't fix this, however making an outgoing call seems to enable the internal mic temporarily (even if the outgoing call never connects)
When this happens apart from the mic not working on incoming calls it becomes also unresponsive for other apps (Tape-a-Talk, Skype, Soundhound etc.)
Conclusion:
It seems to me that there is bug in froyo that keeps the incoming call code from activating the microphone or perhaps there is a conflict of sorts that keeps the microphone blocked. It is highly unprobable i think that the microphone would randomly start to fail on different android phones in the exact same way, so this shouldn't be a hardware issue.
Question:
Does anyone know/guess or can produce a possible solution for this? If not, could you please suggest further testing steps to help reproduce 100% this problem in an attempt to solve it?
Any help would be greatly appreciated as this is a pain in the neck for me (and others i guess?!)
PS: Excuse the thread form, i 'm really bored of writing / reading long posts
PS 2: This is my first post, hello xda community!
samsung vibrant
I have the same problem. I flashed the phone from android 2.1 TO cyanogen 2.3 and from it TO ice cream. I had this problem even to cyanogen and only in incoming call,never in other situation.
Googling I found same information but no solution. Anyone here knows something?
Anyway I found a stupid solution....try switching to 2g( I know that it's not a solution but...). It works for me!
that's ridiculous! how can network state have anything to do with the microphone of the device? can this be related to service providers maybe a more techish member could tell us.
anyway i am on 2g already as i don't have a usim card and this happens even if data network mode is deactivated. glad you found a way out but is it really a solution? i mean you have to ditch 3g for the phone to be actually a phone...
Since we seem to be the only ones among so many to be having this problem i am seriously thinking of taking back the phone for a replacement and hope for the best...
just an update, i lost functionallity of the microphone completely earlier today. That is with outgoing / incoming calls and any app i can think of, so i thought i 'd try changing the network data setting to 3g only since i was already on 2g...
WOW!!! that had an instant effect,it works seamlessly now,didn't even have to reboot.fingers crossed it will last.
that is one nasty and very strange bug. Please any of the developers could you take a closer look at this?
much appreciated

[Q] Incoming Call But nothing appear on lock screen

Hello,
I recently got lollipop update for my Nexus 5 OTA, After updating my phone i am experiencing issues while answering incoming calls. When i get an incoming call my phone rings and vibrate but nothing shows up on the screen.
I have to press the power button to bring my screen back to life and then unlock it to answer the incoming call. Without unlocking the phone i am not able to answer any incoming calls
This was not happening with 4.4.4. I am not sure if anyone else is facing same issue and i am not able to locate any workaround under settings of the phone. Any help on this will be highly appreciated.

Unfortunately this is a known issue that hundreds, if not thousands of people have been experiencing and reporting ever since the phone was released a year ago. So yes ever since 4.4, before even 4.4.2. Even more unfortunately it is a known issue that neither Google nor any carriers admit to own up to. Anyways to my knowledge no one knows if it is a software or hardware issue, but it is most likely not a carrier issue since it is reproduced on multiple different carriers. Anyways I will link you to the Google Forums thread that started on this issue a year ago and has hundreds of people posting and reporting it in that thread. You can find that post if you click right here.
The only solution is a work around, not a permanent solution. If you find out that someone called you, and the phone did not ring, restart the phone. It seems to have resolved the issue temporarily. I always restart mine every 2 to 3 days anyways to try to prevent it as little as possible, so that is what I would suggest. Also maybe state on your voice mail if you did not pick up to leave you a voice mail or send you a text so you know they called, because you been having issues with calls on your phone. That way you know someone called, because you will still get the text message or voice mail notification.
I had the problem mentioned in the second post (which may not be what OP was describing) and I solved it by trying out different radios. Latest one with Lollipop is fine, but the two before that weren't good.

[Q] big Call volume issue

I purchased my OPO two months ago and it was fine even in the call section. I love this phone but recently i have been facing a problem. When i place a call or recieve one then the person om the reciever's end is not able to hear my voice clearly. It's too low and sometimes my voice is also distorted. I have tried flashing various radio zip and also updated my phone to 05q, i came back to 44s and still i am having the same problem. I Googled it and i saw that some of the users are also having the same problem. When i reset my phone this problem gets solved but as soon as i download some apps.. I again start facing the same problem. It is quite frustrating.. Other than this.. This phone is too good. Please guys can u help me. Is there a way i can get rid of this?

hmm no replies. anyways i fixed this .. it seems it is really a big issue for oneplus one, they call it "robotic voice" and the fix is really simple. disable the "ok google" feature and delete your voice recording on it as well.

Headset call issues - other side can't hear me

hi all,
i noticed that during calls with the bundled headset (mh750) after rough 3 minutes the other side suddenly can't hear me, but i can hear them.
the receiver just thinks that the call has dropped.
I tried also another headset (of an old htc pre-android era) but the issues is still there.
googling for some minutes i read that there was a Android 5.0 bug that gives similar issues.
I'm not sure if it's a Hardware (z3's) issue or a software issue (android)
my firmware is 5.1.1 - 23.4.A.0.546 on d6603
Hello,
I have the same issue, after some days i lost the signal, ( with the stock firmware ) the phone was never rooted.
After i send to service, they told me the phone can not be repaired because this is related to mechanical shock, also i lost the warranty.
I'm not sure if this is ture.
Best.

Google now issue. Disable voice activation on any screen setting. Should fix it.

Know about phone fixing? here's a challenge for you!

Hello! I'm going to need some help on someone that might know more than I do.
Here's the challenge:
Phone: Samsung Galaxy S7 AT&T Unlocked (G930A)
Build: G930AUCS4BRA1 (latest)
This phone has two really hard to pin down issues that will surely make a challenge.
First one, is the microphone. Calling or receiving a call makes the person on the other end to hear themselves. It is not explained by the other person using speakers, since it happens 100% of the time, even testing it with the express instruction to not use a speaker.
What the hard-to-pin-down issue is? It doesn't happen with any other calling program. I can voice call from WhatsApp or from an app from my provider using Wi-Fi or 4G and the issue disappears. Only happens if I receive or make a call from the phone without using Internet.
Second one, is a new one that happens randomly. The phone freezes, shuts down and restarts in a loop, about 3 or 4 times, and then works normally. Happens about 2-3 times a day and started two days ago, without any physical damage as a cause.
What has been done to try to fix this issue?
Cleared cache
Phone reset
Installed updates (twice, one from 6.0 to 7.0, and then updated the build number), once by using Odin, and the other one to update from SD Card.
Nothing has fixed any of these issues.
Any ideas?
