Bad sound quality

There was a thread here about that the voice from the earpiece is distorted. I experienced to have a similar problem. From the first day the sound was excellent but in 2 months it changed to distorted and then become very-very weak. At the same time the sound was good if a loudspeaker is on or if the hands-free is connected. Thus, I supposed that the contact becomes bad. To fix it, I disassembled the device. The *.pdf-file how to do that is included (33 megs). When the contacts were formed so they touch firmly the corresponding places on the printed board and the device was assembled, I heard nice voice from the earpiece.
So, in some cases the problem with the sound may be due to weak contacts. I suppose the contacts may become poor because the material for the outputs on the earpiece is not so elastic plus influence of vibration from the vibromotor plus influence of humidity.
Backup the system before disassembly because during this the backup battery may discharge completely!

Sorry wasn't logged on...

Thanks a lot I got this problem long time ago but I don't know how to disassemble it so I always try to shake it to fix ......

Great ! Very useful
Thanks

thanks for the guide..... very useful

Where can I find the 33meg pdf? I need to disassemble the device too...
regards

That is what I thought th first time I opened my MDA Compact! Believe me I am the very first one I did when the device first came out! After lots of research let me tell you this:
IT IS NOT THE CONTACTS! IT IS THE SPEAKER! The membrane is of low quality when you open the device and "fixing" the contacts it will only make it to work for a few phone calls up to a couple of days at most! The speaker is burnt by the high amount of volume the motherboard of JAM gives to the speaker! If you want to solve your problem then you ll have to find a Nokia Center and buy a speaker for a Nokia 6610! Nokia 6610 and HTC Magician have exactly the same speaker! The only thing you have to do is to change nokia's black cloth ribbon on the top of the speaker with HTC's black rubber get it into your magician and there you are! You have a perfect sound again! My only advise is to use the call volume just a click less than the maximum volume so you won't blow away your new speaker!
I dissasembled and reassembled my MDA compact more than 11 times trying fixing the contacts with no permanent result! After replacing the speaker with a Nokias's 6610 speaker everything seems to work like a dream for at least a month now! :wink:
Its much more easier to get Nokia's spare parts than HTC's! The speaker cost me 18euros!

any chances you could post us nice pictures of these manipulations ?

I would love to do that but please I don't think that my magician could survive one more disassembly! :twisted: In case of replacing a friend's speaker next week who has the same problem I will make sure I get those pics! Magician is extremely easy to be taken apart! The only hard parts in the removing process are the upper backplate which has to be removed very carefully in order to be fitted back in its place afterwards and the front faceplate where you will need something very thin like a thin knife or even better a razor to take it away from the black plastic on the sides! :wink:

where is the link to the pdf
Hey guys,
I cannot see the link to the pdf. I need to disassemble my Jam too.
Thanx, Martido

Sorry, I found it. Just woke up....

Oh, thank god, I'm not the only one, with this problem. But first i have two questions? Will i loose my warrenty when i open the device? Can O² discover that i opened it?
Did this contact fix solve the problem entirely, or not? Because katsj says the problem is the speaker!
Thank you in advance, such a great community!

Edit:
I read the PDF File and i have to say .. this is simlply impossible! You can cause so much damage .... i dont know where to begin. One small mistake and you can't forget your PDA. I think this is highly to dangerous. Is there no easier way to solve the problem ... some ideas??
Or do the pictures lie and it isnt that complicated??

My sound disappears during call...
Strange, during a call after a few minutes my sound disappears. I can hear the other caller, the other calleer can't hear me anymore...
But now I found a strange solution: when I pull up the volume button n the left a few times (it was already at maximum!) my sound is back!
Has anyone the same experience or a better solution?

I think when you pull up the volume there is this small tone and you hear this tone from the loudspeaker.
After you hear the tone, you cant here anything again, right?
I'm driving really crazy, i loved this XDA Mini since this prob occured and i want to find a solution as soon as possible ! I really dont know what to do
When i push against sd-card slot from inside, i hear everything .. again, so this is just a really small prob ..
I hope sb. find a solution quickly otherwise ... i dont know

I think it's a contact problem, so maybe the problem isn't that small... I don't want to open my device.
I don't think it has anything to do with the ROM or with the software.
(I wish it would, then there would be a solution in the end)

I had this problem too and found a fix:
I assume that while you are making a call, there is no audio from the earpiece. While on the call, adjust the volume up or down with the volume slider button. if you hear faint beeps and faint audio right after the beeps, your earpiece is working but there is a software glitch caused by the headphone jack.
Reset your device. Make a call (i.e. to your voicemail) and make sure there is audio incoming. Connect the (wired) headset. Disconnect the headset and you shoud now hear audio from the earpiece. You may have to reconnect/disconnect the headset a few times.

thanks
thanks for the pdf. ill check it right away!

U ROCK
THX GUYS>>>U ROCK...........I was soo worried.....
thx again..

Thanx dudes for the nokiaspeaker tip!
Just received my on ebay ordered nokia speaker and within a few minutes I fixed mine magician thanx to the pdf & already gainted knowledge on this page!
I bought this phone a year ago for a very nice price because of the damaged speaker and now at last I repeared it just for €3,- (instead of sending it to Orange risking over €100; I`m Dutch ya know )

hi guys...pulling this one out from the past....my magician has all the symptoms above, but with no luck, the replacement speaker did not do the trick...any other ideas/details/downloads....anything to get the audio back???\
BTW, i can hear glitches of sound if i play with the volume tab. That is to say, if i push it up, i hear the tone "ding" and i can hear the voice on the other end for a split second! So i must be close, no????

Speaker Problem

ive only had my universal for 3 weeks now and the speaker ontop of the headset seems to have gone.
the nowmal speakers work and the mic is fine.
is this an RMA job to O2 or can this be sorted with an easy fix?
cheers guys

You mean the Spkear on top of the device while you keep it closed?
If yes then its not only you... everyone have the problem...
The speaker on top of the device while its closed it having disturbance and even some time makes some funny noice, but if you keep the screen fliped and open, u can hear it clear.

Not true. My Exec works perfectly with all four speakers. The speaker that's used when the lid is closed (and screen hidden) is the one I use most often. No problems for me, and I haven't seen anybody else on this forum mention this problem until you two.

my mic packed up after about a week

Well sounds like it might be hardware. If you've done a few hard resets and tested before installing any software and the problem is still there sometimes, then I'd say it's hardware.
The m/board on the Hermes is not one that you can really work on with ordinary soldering tools. A repair shop could check by using a heat gun to check the contacts on the Mic. If that fails then it's likely either the mic coil or a problem with the contacts at or coming from the USB connector.

I say something more. Now i hear myself on voice note but really quiet like 1/10 normal volume.

Yes, but even with an open circuit / damaged coil, cracked connection, you can sometimes have sufficient leakage current to get a faint response from things like microphones and speakers. I still think it's probably hardware - but thoroughly check all the software possibilities eg clean install, stock ROM etc.

Hm i open hermes but im noob in that stuff so everythink look fine for me with microphone. I clean that think to protecting microfone. The problem of couse dont disappear. But.. its look like always when I plug in usb to spv, microphone start working fine.. Not always but moust of time it is solution.. If it is a hardware what i should to recommand to replace in service? Microphone?

ignore me, re-read what you put and decided i was a nab

[Q] Echo in calls

Does anybody else have problems where the person you call hears them selves talk? There voice is echoing!
Does flashing a custom rom stop this or is it because of the Crystal Talk stuff?
Thanks

It is possible that you're using speakers and the voice is so loud that they actually hear themselves? If you have not flash a custom rom and you're on official rom then no, you should ask the company to look into this if you still have the warranty.

It's not on loud speaker and the volume is at the lowest point. I only got it on Thursday arranged for it to go back.

Does it do it everywhere? I have had problems with all of my tmobile phones on occasion. Not sure why. My last phone used to do it all the time. Very annoying. Only had it happen once with the defy in the last month.

Never had it before with any phone I have owned. It's seems to be worse when i'm outside when the wind is hitting the second mic, also when this happens it sort of makes it sort of sound like i've got my head in a box when I talk. Hope that makes sense? Iv'e tried all the call quality settings but it's still the same. It has to be this Crystal Talk Type or what ever it is..
Thanks for the reply guys.

Our of curiosity, while this is happening, have you tried opening the usb cover to see if that changes the sound. There is at least one report of a "pressurized" effect on the Defy (as it's sealed) causing sound issues, relieved when the ysb cover or battery cover are removed.

hhmmmmm interesting, I did think about the hands free speaker being behind the battery cover when I tried calling someone and they said it was terrible echo.
I'll go and try it and let you know.
Thanks

Tow problems after installing some phone parts

Once I dropped my huawei ideos x5 on the floor, opened up, and headed up the exterior glass.
Rode fine at least went well (had already once changed the low screen) did a factory reset. Got two problems:
When I make or receive calls I can not hear the voice of other people, but they listen to me.
The row of keys m, k L to the right of the phone does not work, just turning 90º the screen.
This can be derived from what? Contacts can be in the assembly of the phone?
What can I do?
Thanks.

Hi,
can anyone show me a photo from earphone and his contacts?
Thanks.

Did you mean photos like these? http://imgur.com/a/biJBG#0

Hi zazza8,
Yes those photos helpe me. I've placed the parts just like the images, more precisely the earphone but still can't ear people on the other side!!!
What could it be the reason?
Thanks.

Sorry, I have no idea.

If you plug the headphones in the jack do you ear them or not?

Also you may try connect Bluetooth phones - so no contacts or wires are involved.

Thanks guys.
The mobile died from another problems.
