Weird NOISE/crackling during call - DESIRE HD - HELPPP

Hello , i recently bought the Desire HD, and havent been experiencing any problems with it except of one quite annoying.
When im in a call, either outgoing or incoming, the speaker makes a weird crackling noise.
This happens always, and happens on both the phones speaker, and loud speaker (depending on which is selected during call), and headphones(when connected). Ive searched the forum, and some people have been experiencing a sort of problem, but not on the same device.
any help is very much appreciated thank you

I can verify that I'm experiencing the same with my Desire HD.

We discussed this issue already in the german "Android-Hilfe"-Forum. This buzzing, crackling noise seems to affect a small number of desire HD's. Mine was affected too. All the devices have been changed on warranty with no costs for the customer in germany. No matter from which provider they were bought.
Edit: BTW: Wrong Forum, I think. Could an Admin move this thread please?

Thanks for the quick replies guys, appreciate it

Hi All,
My Desire HD has started doing this today too! Really gutted. What has HTC UK support been like this on it? Replacement or repair, and how quick? I dont want to be without a phone long! Is this a widely recognised problem, apart from this thread I dont see much on it. Im wondering if the buzz comes from a loose LED flash cover vibrating caused by the speaker?
Thanks very much

I have the same and I thought it is the proximity sensor opening and closing.
Are you guys sending it back for replacement or are you going to live with it?

i have the same problem it sounds like the earpice is short circuiting for 1/10 second
i dont know is it a general problem or only limitted to our handsets
and if we update the radio version is it going to disappear or not
any help is appreciated

I sent 2 support cases to HTC at the same time. The one was for tjis issue and the other for something else. The other one was answered next day but for that one, not a word. Does this tell you something?

didnt understand you sir.

I say that: I contacted HTC support in regards to this but haven't received a reply. But, I have received replys for other cases. And this doesn't sound good.

i have the same issue

Issue with noise
I recently replaced my DHD due to a similar issue. I found if my hand palm was making contact at all with the SIM.SD Card cover, ie the antenna I would get an extremely high pitch feedback sound. Also if phone was on charge the crackle sound was audible.
Orange were great and replaced the original handset straight away at no cost but the replacement also appears to have the same issue. For the moment I'm considering contacting HTC direct but i'm not sure as otherwise I love the phone, and truly believe it is the best on the market.
I think the issue might be resolved if i get a outer protective cover so I'm going to try that first, and not use the device while on charge.
Would be good to know if others have had these experiences.

Whatever you decide, contact HTC so that they know and work on the problem. As I said, I contacted them but never received a reply which means that they are aware and have no solution.

That must be a different issue. I hear that noise via BT headset when I don't even touch the phone. I believe it's due to the sound frequency change during a call and the low quality speaker cannot handle. It's like using a high wattage amplifier on a low quality speaker and expect to hear deep bass sound. I guess you all know the result of such sound.

I'm also experiencing this problem. Sent the phone in and got it back but the problem is still there. They changed the motherboard and the loudspeaker but that obviously didn't fix the problem. So now I probably have to send it back again.

i just hope this problem can be fixed with software..

hi all,
in my case occasionally during call's even whit sound volume low a ear the person talking with " extremely high pitch feedback sound".
It's a very good phone but that problem is starting to annoying me.
i allready send a email to htc portugal and their response was to send the equipment to the repair center
in you opion what should i do? send to repair?
Thanks

Have you tried enabling the SRS improvement? It can be done in the music player. It made the crackling sound during calls in my device disappear...

I will try this and post back...
What I'm experiencing, when I'm on hold with my service provider (Vodafone AU) I can hear the normal on hold music then at random intervals just for a half a second or so the music cuts and there's an annoying crackle noise. Sometimes there is no noise for a while then there can all of a sudden there can that crackle noise every few seconds. Like another person has said for me if I change to loudspeaker it still does the crackle noises and turning the volume down doesn't help. I've tried taking my hand off the phone but it still happens. I have noticed a few times the reception bars icon, drop a bar or gain a bar when this noise happens so maybe there's a link?!? By the way I'm running LeeDroid 1.4.1 (wich is based on HTC's 1.72.405.3 ROM). Also I'm running the Jan 17th Radio version: 12.39.60.19U_26.06.04.06_M.

Right. This could well sound daft but try it anyway! Someone on another forum said it worked for him (her?) and it worked for me with a Nokia E71. The speaker was 'crackling' so I did the usual googling. The answer was, for me, to suck really hard on the speaker a couple of times. Basically the diaphragm gets put out of place and the 'sucking' gets it back.
Try it and see! Though it won't fix the 'feedback-type' noises I'd guess but I find most of those are specific to a particular call. Either call back, or get them to call you back, and all is well.

[Q] Wi-fi issue turned screen issue...

Hi guys
Need a bit of emergency help (or maybe a hug).
I had major wi-fi issues and believed it to be the usual antenna problem described everywhere. In my wisdom, I thought the procedure to sort out the connector under the back-cover looked easy.
It was! I opened her up, "re-sprung" the connector - all good. However! My screen will now not switch on. There are no obvious issues internally or externally - I think I know which connection on the motherboard is for the screen but still nothing.
The phone is definitely on as I am getting notifications. Can anyone suggest a possible issue I have overlooked? Maybe a hidden connector somewhere? Or is it off to the mobile phone shop for me.....?!
Thanks
James

Probably not what you want to hear, but was it actually really simple to fix the antenna?!

Haha - yes. It's quite obvious when you open it up what the issue is. The connector is a small "spring" that makes contact with some copper plate on the backplate. This spring obviously gets depressed too far and won't spring back to make the desired contact. In theory, easy to fix. In theory...

M8: Microphone not working (sometimes)

Hi,
got my M8 (dual-SIM) for a few days, and noticed that someone people can't hear me properly. I was sure it is network coverage related problem.
However, today I have decided to test the microphones using phone diagnostic tools and using sound recorder.
In most cases microphone works. But sometimes instead of my voice I hear noise and NO VOICE at all.
What is the conclusion, is this software or hardware related problem? Don't want to do factory reset for nothing.
Thanks in advance.

Anyone ?

My microphone started acting up about 2 weeks ago on my Att model.
When using headset no one can hear me, switch to speaker and they can. Record a video and I can hear background noise but voices are so low they are nearly inaudible.
Hell, I have to scream at the phone to get OK Google to work.
Wish I had an answer, but like like it's going to be a warranty issue. Till then, I'm using tasker to turn on speaker phone for all calls lol

It sounds like a hardware problem.
Are you rooted and do you have s-off?
If you are, you could try flashing the newest firmware and/or adsp to see if that fixes stuff.
Are you rooted? What ROM are you using? Have you updated you ROM to 4.4.4 without updating the firmware?
Give a quick list of tweaks you've made. Also, go to adb and enter "fastboot getvar all" (no quotes) and post the read out here. Please remove your IMEI and serial# for your own security.
If it is software related, this is pertinent information.

Hi,
My phone is 4.4.2 official, not rooted and it is S-ON.
I am waiting for official 4.4.4 update for my dual-SIM M8 (it is expected in next few days).
P.s. in last 2 days nobody reported they cant hear me...

Today, problems returned........ 50% of the calls today people can't hear me well, or they can't hear me at all.
However, it seems that turning speakerphone ON and OFF during the call completely solves the issue (for each call separately).

Just a head up, anyone having this microphone issue should try cleaning out the left side of the bottom speaker grill with a toothbrush and some 99% alcohol. About 5 min of scrubbing pulled out allot of crud and now it's back to normal.

I really dont understand how did you manage to pull anything from the bottom speaker... holes are so tiny. Please try to explain or take some pics.. as my mic is driving me crazy.

Can't take pics as I only have the one phone but I'll try to explain what worked best for me.
Isolate the front most bristles by using your thumb to sort of bend them away from the rest.
Instead of using a scrubbing motion, lightly place the tips of the bristles against the grille at about a 70° angle. Keeping that angle, move the brush slowly across the grille keeping just enough pressure so the bristles go into the holes. Don't put so much pressure that they flatten out.
Do that going both from left to right and right to left.

[mic_issue] [devs_help_asked-needed!!!]

Hi, Many Users Like Me Are having Mic Issue, i'm using XZL, but the main idea can be adapted "IMHO" to any smartphone facing this annoying issue,
After testing my XZL: Here It Is:
+The Positive: 2nd mic the"Cancellation noise mic" is working Fine
-The Negative: Main Mic is not working at all.
The IDEA: a patch "Zip" to "flash" That make the 2nd Mic as Main Mic (With some gain "Boosted Level") and Cancelling The Main Mic,,,
Ok, This IS NOT The best solution, But For The Ones Who The Hardware Repair Did not Work, This Solution is to Try and can give some positive response.
Ohh!!! i use a "Jawbone"
To DEVS on XDA i've no "Coding, programming" Skills and you Help will let this possible So:
1st Thanks for Reading, Hope the Best.
2nd "You KNOW What To DO" Peace :good:

This.
I have already replaced my mic once, and the replaced mic has degraded in quality, which was not very good to begin with.
I don't know why this particular phone is affected with poor mic response.
Please developers, please a fix to route the input audio from primary(bottom) mic to secondary mic( top rear side) will be highly appreciated.
Just like OP said.
Other Xperia ZL users who are facing the issue, please show support here.
Help us.
I'm on stock lollipop rom, rooted.
Thank you

Hey ZYXPER.
It's funny, I actually encountered the same problem this week. I decided to post it to /xperia-Z instead to get a bit more coverage.
I couldn't figure out whether it was a hardware or software problem. In the xperia service test menu, the front mic would hardly pick up anything, sounded damaged.
Then I downloaded this app:
https://play.google.com/store/apps/details?id=com.grace.microphone&hl=en
Set it to work even without 3mm connected. You can loop the microphone to the internal or external speaker. The weird thing is, In this test, I can 100% verify that front mic still works... I can hear myself very well, and by blowing on the mic I can verify it's the front one. Apperently, the mic is still useable if you increase input volume (gain). Unfortunately there's no app/setting I can find to boost it under regular calls.
I think Whatsapp call usage some sort of auto-input level, because it's much much better in whatsapp and I can make calls no problem.
So today I used a bicycle pump, and put in on the front covering the mic hole (yes really.) and pumped it full power like 10x. No mercy. It wasn't working anyway.
And what do you know, it's pretty much works again! Not sure if it's as good as it should be, but I can make regular calls again. I suggest you try this.

MTCB Joying Display flickering and "burned in" picture

Hey there,
I have some issues with the MTCB. Someone had these before?
First problem which is already quite annoying is that pictures are kind of burned in and still show shadows on the other screen
Second problem which is even more bad is that the display flickers. This is more or less obvious in different scenes.
When looking closely it seems like there is a grid (coming and going in the same frequence like the music is playing?). The attached video shows it.
Especially with white background the flickering gets very bad.
Don't know if this could be related to the Malaysk Firmware I use. Or is is it a hardware issue?
Also contacted the support. Let's see what they say...

Sounds like a screen issue to me, have you checked the ribbon connector hasnt come slightly undone ?

Hi, thanks for answering.

You mean to open the device and check the ribbon connector inside, right?

This is commom in these units.
It's worst when it's hot.
I kinda fixed mine opening it and adjusting some kind of screw near the screen. You turn it and screen gets darker, you need to find a point between too dark and flickering. But when I park my car at the sun, and it gets hot inside, screen get bright again, so flickering and persistent images.

And here is a video about it.

It's commom. That's why Joying even put a video online to show how to fix it.
I believe that when they produce the unit, it's now well tuned up, or it's cold in the factory and they don't realize, so when someone who lives in a hot weather area install it, the problem appears.
It's a bad hardware design, they use analog potentiometer, they should use some digital and automatic one to regulate screen frequency.

Well, Like I said, I ve not heard much about it in the 3 years I ve been following the threads on here, but I do remember Joyous having problems with their screens and 5.1.1 - they couldnt get 5.1.1 to work on their 4.4.4 RK3188 units unless the screen was changed !! Sounds like its more a problem with Joyous units.

I agree there's not many complaints about this problem here, that's why I believe that may be some "quality check" sloppiness. It's very simple to solve anyway.
But all units seems to use analog potentiometer, so, bad design. There's nothing to do with Joying only and the fact they changed screen to update to 5.1.1.
And most users in this forum don't live in hot weather areas. In my case, Brazil, is hot must time of the year, above 34 C degrees (93 F), in the shade.

Don't make me jealous!!
UK weather is great. I've been there once, liked very much.
Some friends are going to travel there later this month. I'm unable to go because my daughter is too young.

Youre envious of 4 deg C ?! I get 34 deg C is a bit hot, but 4 is a bit cold !
Half way between 4 and 34 @ 19 deg C would be perfect

I looked at the map and St. Helena is a little to the south, a direct flight seems a better option.
But feel welcome if you want to come to Brazil someday.
It's a bit messy but it's a good country. I'm not going to take you to meet any favela, by the way. Don't know why tourists are so eager to go in one, it's very dangerous, and I don't think they represent Brazil that much, so many different beatiful places to go.

Hey there, thanks but the video is not working.
I did not open the unit yet to check if the screw will improve. But I will test soon when I find some time.
By the way it's around 0°C here. So not very warm
Attached is another video. The flickering of the right white picture is actually visible. It's not a flickering of the camera.

Just open the unit and fix it, very easy.

Took some time until I tried the fix. But the screw fixed it.
Carjoy recommended a power filter, but since the screw fixed it i prefer this...
The screen is now slightly darker. But I like the crisp image and better saturation of the colors (and of course no flicker).
Thanks!
