Help Crackling during calls

[adfgarga]

My Desire HD is on Vodafone UK. During calls I get a crackling noise every minute or so in the earpiece. It sounds like 3 clicks very close together as if the call has cut out - but it doesn't.

Anyone else get this? I have a feeling my handset is faulty.

Hi

I have a desire barely 3 months old on Orange and the crackling on calls is unbelievably bad. I can barely hear the person on the other line and I have to cut shut my calls as it hurts my ear. I've turned the call volume right down but this still doesn't help. Any suggestions would be welcome.

Thanks

Never had any problem while making calls. Did you contact Vodafone about your problem?

I also get this from time to time ,I have noticed when it does it screen comes on and off I think its to do with how u cover the proximity sensor on a call. I find if I move the phone slightly it gets rid of it but that Might just be me .

I have the problem too. There's actually a thread at xda discussing this. There are quite a few with the problem.

What's the main reason for the crackling calls?

Crackling sound is produced when phone switches between 2G and 3G network during a call. Go to Settings -> Wireless & Networks -> Mobile networks -> Network mode -> WCDMA Only. By choosing that option you force phone to use only 3G networks.
That solved my crackling problems.

I have mine set to GSM only, yet i still get the crackling sound.

Post #7 is right, but it can also occur in some devices during tower and/or roaming issues.

Updating the PRL ("preferred roaming list") can sometimes remedy the noise and/or drop outs, etc.

Dial *228 and select option 2.

I tried everything HTC wrote me in e-mail...from uninstalling all apps, changing SIM to factory reset and unfortunately nothing helped.
Changed almost every option in settings and problem persisted until I switched to 3G only. I have no more crackling sounds for three days now (approx. 360 minutes of talk time for past three days).
I didn't try GSM only since I have 3G network coverage everywhere.

fixed mine.


Ok I had peace for a couple of months now the crackling is back with a vengeance.. Now my alarm is the crackling noise. And even downloaded songs are distorted with the crackling. I read somewhere that it is a yamaha speaker that is the problem. ...
