[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

Wifi-Direct with another phones

Hello. Recently I was trying to use Wi-Fi direct to transmit data to my Lg g2. I manually paired the devices from Settings menu then I selected a file-share-wifidirect and.... nothing! It showed me an empty screen with a Search For Devices button and in a few seconds responded with a message popup "Data transmission via Wi-Direct must be performed with another huawei device at the moment". WTF? Why? Is Wi-fi direct something huawei specific? I do not think so. The odd thing is that LG also allows to pair devices but does not give you a possibility to send data via Wi-Fi Direct forcing you to use SmartShare Beam which is LG-only technology. Why manufacturers are so stupid, they state their product has some technolohy but it's actually unusable! I do not wan't 2 huawei devices and I do not want 2 LG devices! On the other hand my old samsung s3 hanles it in a proper way, I was able to send files from it to both aforementioned devices using Wi-Fi Direct.
I know I can install SuperBeam to deal with my problem but it's inconvenient to install it on every device you want to transmit data to. So I just wanted to know if anyone else had this problem. Also my ROM is a bit old, something like b121(I have MT7-L10 version) so I wonder maybe they have already fixed it in some newer ROM especially the lates ones with Lolipop. If so I will try to install that rom. Thank you.

Homtom HT10 firmware HOMTOM-HT10-Android6.0-V01-20170226

Homtom HT10
a new official firmware has been released:
HOMTOM-HT10-Android6.0-V01-20170226.zip
http://www.homtom.cc/
https://drive.google.com/file/d/0By2t6rTTiNQNcEJ1QkpKQnhzck0/view?usp=sharing
no change log unfortunately
could you please report if those major bugs listed bellow are finally fixed?
is it rootable? if yes, how?
- no OTA update
- losing user language preference (simcard default language is used instead)
- losing connectivity (cannot make/receive calls)
- iris / pattern unlock crash/reboot
- random reboot
- screen calibration issue (not responding sometimes and it cannot be fixed with calibration apps from Google store)
- blurry pictures (slow focus and shutter speed)
- bad audio quality (over saturated)
- clean of malwares and chinese apps
Hardware features that were announced but never won't be available (fake advertising / SCAM):
- 5Ghz Wi-Fi compatibily
- NFC
- OTG
*** UPDATE ***
Ok folks... I removed the simcard and also the battery few seconds and flashed latest firmware with sp_flash_tool (firmware mode not download mode) and lost everything (all apps / data) but there is a good news... smartphone doesn't lose language preference anymore!
unfortunately smartphone is still losing connectivity and network (cannot make/receive calls even if there is network signal !)
(I thought it was solved too because it has worked almost half a day but actually i've still got this issue!)
so HomTom HT10 is still a useless 'smart' brick...
And HomTom is doing the same than UMI: banning from their Facebook page users reporting bugs or false avertising (OTG/NFC/Wi-Fi 5Ghz/full bands support/...).

Got mine 2 weeks ago and have not experinced any of the problem above. I think you have got a bad phone only(fake copy?).
I had a update as soon as I started the phone and it is now HOMTOM-HT10-Android6.0-V01-20170225, hmm yours is 0226.
I am no super user of phones but this one is working very good only the sound when doing the iris thing is annoying.

Mine is the same it's just their typo error. When extracted it's 20170225
Anyway there is a new official firmware... Anyone tried it already?
@ homtom.cc
HOMTOM-HT10-Android6.0-V01-20170510.zip
I'm looking for an English (or global) custom ROM for this device running Android 6.x or 7.x
MoKee, GizROM, LineageOS 13/14/15. Any ROM 100% working.

I bought one of these a while back and using it on the T-Mobile network for over 8 months. I also have not had any trouble that you stated above such as loosing connectivity or the iris scan crashing. I do agree that it would be nice if you could turn off the iris scan noise though. Love this phone and glad I took a chance when ordering it.

I may have found this thread a little late, but here I am. I have the Homtom HT10 running the firmware Android-6.0-V01-20161202 and I was able to root the device using Kingo Root. It's been a while, but I think there were some additional steps to go through before this root worked. My question is if anyone here has had success in rooting one of the newer firmwares, since I'm not sure if this root would survive the firmware update and I wouldn't want to lose root access.
Also, does anyone know how to replace the Kingo Superuser app with Chainfire's version?

mine was working good, i rooted , and install magisk and after a while i loose connectivity when make calls..i flash full firmware..format and all the stuff and still cannot make callss

I've flashed HOMTOM-HT10-Android6.0-V01-20170622 and so far all works pretty good (it keeps the language)...
Only audio EQ quality is poor (distorsion) and volume / quality issue in phone calls.
Not sure yet if OS is able to switch properly from a deficient 4G network to 3G/2G (because i'm currently using forced 3G mode in settings) but it seems to work better than previously.

flashing the Rom
Hi guys. I'm having trouble loading the latest firmware thru sp flash tool.
I'm running Windows 10 and I've installed the extra drivers.
Would love some help.
Thanks

Did you have to push any button combinations to get SPflashtool to start?

I used a different version of flash tool and it started when I put the battery in. There's so many versions of flash tool I guess. But I got it working.
Thanks for the response!

My HT10 (got it a month ago) GPS not working
Hi guys
My HT10 GPS in to working. The phone is new, I just got it, and it literally only has viber and Here maps on.
The GPS tested today, not working.
Under a sky with no clouds in the middle of a field with no obstructing buildings and no signal whatsoever.
custom build version: alps-mp-m0.mp9-v1.33_aeon6797.6c.m_p11

Hello
I am french and I live in Ireland.
I have same problem with my Homtom HT10. My smartphone is still losing connectivity and network (cannot make/receive calls even if there is network signal !). I indicated the problem to Homtom who asked me to update Firmware but it did not improve the problem. Homtom suggests me sending back the smartphone for repair but postal charges are very expensive for China.
No solution... I have to restart my Homtom all days if I want to send a SMS or make a phone call.
Perhaps a problem with the SIM Card ?

I got mine since 4 months ago.
Probably the worst android I ever got.
It is fast ok and charge is really quick but its always losing connection. Its more like a photo camera and mp3 than phone.
The other stupid thing is that can connect Wifi 5Ghz and the 2.4 is really slow.
I have already stock firmarware 20170622

Serious Homtom ??
Hi
My question to Homtom :

No Voice Transmission during Phone Calls

(Duplicated from previous post as per suggestion by admin. See here: https://forum.xda-developers.com/general/help/voice-transmission-phone-calls-t3690651 See Addendum notes)
Hello! Long-time lurker, first time poster.
I have a sudden problem with my Android phone (Samsung Galaxy S6 running Android 7.0). Hopefully you bright gentlemen and gentle-ladies can help me:
Approximately 1 week ago (edit: 3 weeks ago), my phone stopped transmitting Voice data on phone calls. I cannot hear what the other user says on their phone, and they cannot hear me, however, pressing number keys DOES transmit the dial-tone to the other user (both ways). It does not matter if I call them or if they call me. It does not matter where I am physically, I have tried in several locations around the city (likely on several towers). It does not matter if they are using a mobile or land-line. (Addendum: Hangouts dialer functions perfectly with the hardware, before and after factory reset(s), Bluetooth headset works with Hangouts but not regular Phone)
During this time, all of my data connections work fine. Texts, Email and Browsing is unaffected. Phone performance is normal.
Since this has occurred, I have:
- Simulated battery disconnect
- Wiped Cache Partition
- Force-stopped the Phone app (all three instances)
- Verified the physical Microphone is working using the Voice Recorder app (it works fine)
- Booted the phone in Safe Mode
- Contacted my service provider to check in there was any problems with my account or transmissions.
- Transferred my Sim card to another device to test if my card/connection was ok. (Voice worked 100% on the secondary device)
- And lastly today (two weeks ago); Completed a Factory Reset
(Addendum:
- Flashed stock firmware from Sammobile via Odin
- Attempted to clean out the Microphones with toothpicks and blunt metal objects, just to be sure
- Plugged in and removed a wired headset as well as checking for debris)
I am sitting here now trying to understand how a hardware problem could possibly cause a failure of Voice encoding on only one app, and how to fix it. Or how a software problem survived the Factory Reset (and Firmware flash) into the fresh install. I did indeed try without any 3rd party apps being installed, without even adding my Google or Samsung accounts to the phone, just plain old Android; no dice.
Any suggestions?
I recall one fixing another phone that had a problem with its Capacitive Touch Screen being not sensitive enough/not reading presses problem by accessing a special menu that allowed me to re-download the driver. Is there anything like that for the Voice? (Addendum - I have looked at all the star ** codes available for this model and tried several, nothing has worked so far)
Thanks!
Thoughts today (Oct 31/17): I am not sure that flashing a custom rom is really what may fix the phone. I am willing to do so, but it is somewhat frowned upon by Canadian carriers (or at least it used to be). I was curious if it was a problem with Noise Cancellation or an SD Card problem as those are issues brought up when googling the issue. My current plan is to flash to a stock Android 6.0.1 and see if the phone works then. If so, then try the standard upgrade path. Any suggestions will be helpful!

Phone functionality intermittently lost after upgrading to P

If my phone is on for more than 10 minutes, I lose calling functionality. When I try to call someone, it freezes and the Pixel becomes unresponsive, forcing me to hold down power for 10 seconds for a reboot. After this, it works just fine for another 10 or so minutes.
I have no idea when calling functionality begins to be lost because I can still send and receive texts, but I can't make or receive calls. I don't even get a wave of missed calls or anything when it works after a reboot.
Google Assistant has it's own issues when this happens too. It won't come up with "Hey, Google" at all. When I long press the home button, Google Assistant comes up, but I just get the floating dots. Fortunately, it doesn't freeze when I try this. Restart the phone and I'm good for about 10 minutes or so. I tried installing 3rd party calling apps, but the problem persists.
Hoping this is a Pie issue and waiting for the next security patch, will likely do a sideload flash-all. Any suggestions as to what the problem is from? Could my SIM card be the problem? Any apps I could try to help narrow down the issue? I had no issues with Oreo.
Thanks in advance.

Tried rebooting in safe mode. Slightly similar results: works fine for about 10 minutes but then it's just the mic not working. I can make and receive calls with out the phone freezing, but no mic.

I have a similar issue with a used Pixel I purchased. I couldn't place or receive calls, with everything else working fine. Did the prerequisite online searches with results finding most everyone experiencing this issue chalking it up to hardware but I'm still thinking software. I tried a different phone app (drupe-enabled as default) with some success, then the problem returned (a few days later, rarely get/make calls). The default google phone app (version 23.0) fails every time. Currently looking into TWRP/Root and hoping to eliminate certain default apps to experiment further. Will be keeping an eye on this post! :cyclops:

Could there be an issue within google play services with phone dialer app (any/or stock app)?
After continued issues I parked phone in drawer a bit then pulled out and tinkered with a few weeks later. Tried to isolate problem using logcat and on a hunch I flashed TWRP and a custom ROM but NOT any gapps package. Sticking sim in and using the built in phone app (Resurrection Remix -com.android.dialer) it works without issue. What? I flashed gapps (correct version/etc) and sure enough the problem returned. Went back to rom minus gapps, works fine. So, with straight up stock rom - stock phone dialer fails, custom rom - it works without a gapps package but not with.

Went back to Oreo before I had the problems and... problems persist. I'm sad. I had the privilege of speaking to someone from Google Support who was very knowledgeable. Unfortunately, my best option from the rep was to take it in to one of their authorized repair places.

Are you guys on Verizon? I'm having this problem with my dad's pixel on vzw.

See my updated post (# 3) for what I've tried since..

Vzw ended up replacing my dad's phone through extended warranty. I talked to Google for awhile. Multiple factory resets, factory image installs, tried older phone apks. Nothing worked.

Older/newer phone dialer apps didn't work for me either ... custom rom and eliminating google play services did (no gapps). I'm still tinkering with the device ... installing frequently used apps using F-droid and Yalp, will test it. Not quite sure why but it works.
I ended up flashing Lineageos for Microg, presents it's own problems in the learning experience but it works.

Nothing ever worked in the end. No, not with Verizon. Bought through Canadian carrier called Fido.
Called Google tech and they weren't overly helpful. I started a chat with a Google Tech and they suggested I take it to UBreakIFix. They did a free diagnostic test and I referenced https://support.google.com/pixelphone/forum/AAAAb4-OgUsIW_gxTpXX3s/?hl=by that thread. Said they'd fix it for free even thought I was out of warranty. Got a new motherboard and my phone works like a charm.
