Mic Problems

[phantom201]

Hi Everybody,

My Magician recently developed an annoying problem and I wonder if anyone had this already:

The internal Mic occasionally goes to a very low sensitivity, i.e., when talking on the phone I have to scream so that the other person can hear me. This is also valid when recording a voicememo - on the playback I hear mostly static with a faint voice in the background.

Next, when using the headset, the voicememo records Ok but when talking on the phone, the other guy ears mostly the electromagnetic noise of the GSM (a loud "RRRRRRRRRRR").

I have noticed that this effect of the headset is started when the battery voltage goes below 3.4V and, as i connect the charger, the effect disapears.
I cannot relate the effects on the internal mic with the battery charge though; it seems to be more random....

It definitely is Hardware...but could it be solved maybe with a new battery?!

Any hunches?

Thanxs!

that is actually aproblem faced by all magician users. mine too worked just fine for firts 6 months then this annoying problem arose.
others could barely hear me.
i tried every sort of registry tweak, cleaned the mic and other thing but still nothing fruitful happened.
one fine day in an attempt to fx the internal mic myself i broke it (there is hardly any service backup for o2 devices here in New Delhi)
since then either i don't use it or use it with a bluetooth handsfree. no problems with bluetooth handsfree.

Yep, That´s right: No problem with the Bluetooth, but is just annoying to have to worry about carrying the BT device all the time and being always worried about its battery state - not to mention that I already lost one...
My guess is that the Analog-to-Digital Mic Chip is failing, or some part of the Mic circuit before that, or even the power suply to the said Chip....
That's just a lot of guessed troubleshooting to do without the knowledge of the elecronic circuit itself.

BTW, I just read your post about the mic problem - Did you have the problem as well with the wired headphones?

Thanks.

no! i don't face any problem with bundled earphones or even nokia stereo earphones or a bt handsfree even if i talk from a distance.
problem is only with internal mic.
i would suggest not to try anything yourself on the board. u may ruin ur device like me.
and yes, its annoying to carry tha bt set all the time. thats why i seldom use this devica anymore...i use it only as a mp3 player paired with sony mdr-e808 earphones and equalizer app. the sound is very crisp and punchy.

ok whose ready for a big surprise?
you're very right! its a hardware fault

i have 100% jumper solution

call +92-300-3812680 if you know a bit of soldering

Faisal is very right buddy......it is purely jumper problem. I attached a snap of my Cell for you.......See the arrow... It is mic and we have to put the black color jumper on it.... Actually what happen with us.... we don't pay much importance to that jumper... there is a tiny whole on that jumper, put that whole on the head of mic so that our voice waves travel inside the jumper and go into mic.

It is my own experience that I put wrong side of jumper on mic and got panic three times :). Thanks Faisal..... ;)

DUH!
nooooooooooo!

i meant a pure jumper solution silly!...

the jumper solution is a quoted wire or in combination solded n jumped from the main sources or the parts in between to make a proper current flow in case of any resistance in between, loose or broken connection.

unfortunately the solution i was supposed to provide was scheduled that night is delayed due to some very sudden technical reasons. And for this i really apologize.

ill try to be as prompt as i can but the time cannot be defined so please forgive me for bringing hope and than delaying it. i know exactly how it feels but hey... patience can be more fruitful :)

Be Good! Be Well!

You are right Faisal......... but I told everything which I demonstrated...... And I solved the problem.... It can be possible that other people also did the same mistake which I did.... They can check their mic cover, as long as you can’t provide them any solution. Right??

For the main problem of the buzz noise when calling: I had it too. And it became gradually louder, more louder. And then (it became REALLY insopportable: when in call even the main speaker emitted that noise, and considerably loud) my phone resetted. It decided to not woken up unless I took the Sim out, and that was the end of my phone (the "phone" part: I used it as an expensive mp3 for quite a while). The noise was so loud that also attempting to connect to the carrier caused soft reset. Searching around I discovered that noise to be related to RF leakage.. you have been warned folks :cool:
