Hello all!
First, thanks for an awesome forum! It has both helped me tweak my Wizard, and also get help when I have needed it.
Well, I have no choice now but to ask here. Last autumn, my warranty was almost up, and a wierd problem presented itself. The mic and speaker suddenly just stopped working! The sidespeakers still work, I think, because the phone rings when someone calls me. But the caller can't hear me, and I can't hear the caller. And there isn't a hint of sound in it, no static or noise, there simply is nothing.
As there were only a few days before the 2 year warranty was up, I ran to my dealer and turned it in. A few weeks later, the phone returned, working again. But now that I come to think about it, I don't remember if I got a replacement or if they actually repaired it... It looked a little like they handled it rough though, maybe it was another phone... Well, that's not important right now.
The same thing has happened again! Summary:
1. Mic & phonespeaker dead
2. Stereo speakers work under certain conditions
3. Wired headset that came with the phone works, both for calling and media
So it seems like a hardware problem. Please note, although I downgraded the phone to original, official Swedish Qtek 9100 ROM, it has been thoroughly tweaked and upgraded to a number of different WM6 ROMs - but all that has been working beatifully!
Still, what are the odds for the mic&speaker dying twice in a row, on different phones (i think the present one is a replacement)?!?
Question: Does anyone recognize this? Is there a possibility that it is software related, and maybe fixable? I have searched both the web and these forums but haven't really found any information on it.
ANY input would be greatly appreciated!
Additional information:
Qtek 9100 (Swedish), G3 model, WM6 upgrade successful (unlocked)
EDIT: There are no system sounds, which is wierd, because the phone can still ring. I thought the system sounds came from the stereo speakers on the sides of the device?
Hello all!
It is a glorious day to be alive!!! Or to have a fully functional Wizard, at least!
Lol - my topic isn't very old, and i reply to it myself with a solution (?). I Googled after the Wizard service manual, and found it right here on Xda .
In all honesty, i didn't do all that much. I just followed the disassembly instructions of the wizard about half-way through, to the point where you get down to the back of the motherboard. I poked and fiddled enough to locate the mic assembly, only to discover that the mic is soldered to the mainboard of the phone. So, i figured i'd just leave it be, because if the mic is really broken the motherboard needs to be repleaced, or a replacement mic needs to be soldered on there.
After removing A LOT of dust in there (honestly, i think the service center that had my device last time wasn't very careful with anything, even a screw was missing! ), i reassembled it. The flat cable running to the keyboard was also a little skewed, but that may have been me, anyway i corrected it too. Same with the speakers.
Long story short, after successfully reassmbling the phone, i fired it up, called my home phone and voila! I works!
Not much of a fix, as i don't really know what i did exactly, but dust, dirt and some bad connections/soldering may have benn the culprit.
All in all, i'm very pleased with my afternoon here. Thanks for stopping by .

hi epatnor,
I think the problem with your phone was a stucked microswitch in the 2,5 mm connector for the headset. I read about it here in the forum. Sometimes the switch stays in the closed position and the phone still thinks the headset is connected. Thats why all the sound is sent to the not connected headset and therefor your phone seems to be not working (unless you connect the headset)...
But removing the dust is for sure not a bad thing...
For the next time: I think there was an easier solution for this problem than disassembling your phone...

Thanks huibuh_1,
Yes this was probably not the smoothest way of "fixing" it. That said, the stucked microswitch theory would actually fit my problem well - I can see now that the exact problem I was having would arise if such a switch was indeed stuck.
However, I think that the problem would be more intermittent since I actually use that port now and then - especially since it's the only way to talk (besides using a bluetooth headset that is). And since I connect the wired headset now and again the switch is used and moved, I suspect that this would result in the speaker/mic coming online again maybe..? Temporarily at least?
All the same, thanks for replying - this might happen again and with your information I'm better prepared for it!
Well, I just received my 128GB Graphite directly from Huawei. Spent forever checking it over for any flaws right when I got it and found none of the usual one. So of course, after setting it all up for a couple hours, I come to find out the headphone jack is defective. If you plug in headphones, you have no left channel audio. To get audio out of the left channel, you have to grab the plug and pull it towards the left of the phone and hold it there.
Anyone else have this issue?
No issues on my end. Have you tried a few different pairs of headphones? If they all have the same issue, I'm afraid you'll have to get a replacement.
Oh yeah, forgot to include that. Tried 3 different headphones and they all behaved the same unfortunately.
Kind of wish I ordered from Google now. Huawei has no replacement services, just repair. So I have to send them my phone, they're going to open it and repair it. This worries me and I'm expecting my phone to be in worse condition when I get it back considering how hard these things are to open.
Hello. A few days ago I lost the sound on the left channel on my N910F. I tried with different headphones (and also my headphones on other phone). The headphones are ok but I have no sound on the left channel (the headphones microphone works though). I tried cleaning the internal connector as good as I can but no luck, so I sent the phone to a samsung service for warranty. They called me the next day saying they wont touch the phone because it is rooted which voided the warranty.
Is the phones connector a separate module which I can change myself? If so how expensive is it? It also could be the motherboard... I only used dr ketan's rom and emotroid on this phone... I've been rooting and flashing samsung devices sice the S1 days (every iteration) and never heard of something like this.. that's why I'm blaming a physical issue with the connector.
Thanks.

It's the right channel which is not working, the left one is ok. I am now ordering the replacement part, if anyone interested here's how you change it: https://www.youtube.com/watch?v=QsUhVTj6Drc
Only about a week after purchasing the phone off amazon brand new, only one side of any pair of headphones i plug in works. Any way to fix this? Would like to avoid using manufacturer's warranty so i am not without a phone for a month while i wait for them to fix it.
You sure your headphone not broken? Try another headphone, or try that headphone with another phone
Edit: and make sure audio player / any dsp says "balance" ,
Nope have tried with every pair i own. All work fine on other devices. Even plugged in a portable amp, got a very faint sound to come out of the left channel.
If that's true, then hw problem, I'm not sure you can fixing this w/o going to service centre, hacking (let me rephrase it, DIY fix) your device mean your warranty void,
Or there's actually something w/o dismantling Phone..
Just ask them, how long they can fix this, don't have backup phone? then bear with it

Hey guys I'm new here. A few weeks ago i happened to not notice that some liquid spilt on my phone while driving and i left it there like that for a while . then When i got a call and answered couldn't hear the other person. Then i noticed water on the fingerprint scanner as i had a spigen case and it had managed to get into my phone. I turned off my phone immediately and disconnected everything. Next morning i happened to removed the board and dry it out as i have done this many times before when i changed the thermal paste. The water damage indicator was red. After ensuring everything had dried out i put it back together and my phone powered back on and it charges well. But when i go to play an audio file. I get an error Sorry, the player does not support this type of audio file. The audio recorder hangs and i camera app also works but when i switch to video it hangs. Phone has been reset to factory. Same issue. Sorry for the long story. Need some Help on what part to replace. Is it the mic and speaker that's busted or some component like the DAC. If so where is the Dac located and how can i go about fixing this. Any part websites you recommend I'm from India.
Any help is nice guys. Please
My first V20 was one I bought on ebay that had sound not working. Also the camera was not working. I though it would be an easy fix, well, hoped actually, but it was not. I didn't pay much for it so I though it was worth the risk. The problem you have sounds exactly the same. Software reset won't fix it.
I did get it to work though temporarily. I put the motherboard in the oven for 10 minutes. It worked for a few days only.
The problem is that the DAC chip is now faulty due to water damage I'd say. You need a new motherboard. I would suggest buying a new v20 and keep the old one for charging your spare battery on quick charge! Or you can buy a new motherboard only on alliexpress for about 50/60 euros.
Thank you. I did consider an industrial oven. Could you please help me with temps you used? Was it the same error you got while trying to play a track?
