Crackling noise when I touch the screen

I've been having this issue with my epic for the past month or so. If something (other than a phone call) is playing audio (game, music) through the speaker or the earbuds I hear a crackling noise when I touch the screen and only when I touch the screen. It's very easily reproduced too. For example, I'll have pandora playing through the speaker and it'll play fine until I touch the screen to change the song or do something else. If I keep my finger on the screen it'll continue making the crackling noise until I lift it off. Doesn't happen if I touch the screen while it's off. The same thing has happened on every rom I tried including odin to stock eb13 and ec05. Since I've had the phone for less than a year, can I take it to a sprint store and get a replacement? Or does anyone have any idea how to fix this?

This may not make the most sense, but it sounds like you've got some exposed wires or something on the inside, my guess would be that the capacitive touch screen is causing some feed back when the field is broken and you touch it. May be a bad capacitor, or just some crossed/exposed wire, but we have had a similar issue with a wall touchpad in one of our class rooms. they control a Audio visual box and once it was damaged would produce a crackling over the speaker system when you would use the touch pad to change source or adjust volume and the AV box was turned on. The unit had to be replaced, I'd be willing to bet the same would go for the phone as replacement parts wouldn't be the easiest to come by.

Do you think I should call Sprint first or just go into a store?

Go into the store so they can see the problem personally. They will most likely order you a refurb.

Go to a store, Sprint will tell you that over the phone. haha

This is a well known issue around here. Hold up ill dig up a post about it. I am happy to say that as of Bonsai 4.1.1 this issue no longer exists.

Must be various on a per phone basis then, because I've flashed EVERY single ROM to date and I've never experienced that.

It doesn't sound like a software issue, therefor a rom won't fix the issue. If he goes back to stock, and the issue persists its hardware. Sounds like a loose wire, but I can't be sure...

We were trying to track down the cause, but never did, we still think it might be vodoo sound related when its built into the kernel...
But if it happens on stock, it could be something else, only happens to me on modded kernels.
If you can see this link please take a few moments to click and read, its for a good cause, you can make a difference, help spread the word today...

I've never expiernced this either

Not sure what to say if it happens on stock. Proud to say i've never ran stock except for the 2 minutes before I flashed a custom ROM. And yeah I mentioned the ROM because it does have a custom kernel and even though we've all heard arguments that it's this or that i still have to say it's gotta be something in how voodoo is compiled into the kernel like ecooce says.

So I odin back to DI18 and let it update before I took it to the store and of course it's not happening anymore
I remember going back to stock after ACS 1.1 destroyed my phone a few times (my phone would freeze a lot and since there's no journaling in 1.1 everything would get corrupt) and I still had the issue. Playing air attack hd with the crackling was horrendous. Anyway, thanks for the support everyone. Sorry for the scare

I am glad you fixed it.

Kernel bug. Likely not a hardware issue.
I have the same exact behavior with Genocide 1.0. I'm unaware if this occurs in other Voodoo sound enabled Kernels but it sounds like it does.
On stock EC05 the problem goes away. For me anyways.

It does for most. TWZ 1.4 doesnt have the problem and neither does Bonsai 4.1.1 kernel AFAIK. There might be other known good combos.

I have the same issue on certain kernels. I was just about to ask, too. VERY noticeable when I'm playing music in my car and need to do something onscreen, makes the audio sound terrible.

I had this issue on several roms, including acs and the previous bonsai. In fact, my experience with acs was identical to yours. My phone just didn't play well with it. I don't have this problem with stock plus rom, even with the genocide kernel. Give that one a shot.

Mine also crackles when the brightness adjusts. This includes when the screen fades out when I turn it off.
I hadn't noticed it when simply touching the screen though, just with the brightness. Also, I never noticed it until I started running custom roms with voodoo built in.

Download voodoo control and turn down headphone amplifier or turn down volume limit. Might do the trick.......

Diminished Sound Output?

Has anyone lost like 60% of sound reproduction volume with the upgrade to 3.1? I'm about to do a wipe and reinstall if it's just me, but basically I can't hear **** now.
I used to be able to hear the tablet clearly from another room, not loudly but i could make out what song was playing. Now I can barely hear the tablet when it's in my hands. Is it 3.1 or did primordial do something. Is there a sound mod app? I have looked and my volume settings all APPEAR to be maxed out.

I don't know that it's a 60% reduction but I have noticed it as well.

No change for me. Internal speakers are still plenty loud. Headphone is too quiet, but that was the case with earlier firmware too, but that can to some extent be solved with a free app called Volume+. (It's a pay app in the market, but free if you go to the author's own site, and enable installing apps from outside the market.)
What's hopeless for me is the microphone. It barely picks up anything more than 2-3 inches away from the mic port. To Skype, I actually have to hold the tablet sideways so my mouth is right next to the mic, which seems ludicrous to me. Been meaning to start a thread and ask if others have the same issue.

I just tried to play some mp4s that I have, I noticed that the volume is lower too.

It was anemic before and possibly slightly more now. The overall volume (or lack of it) is the only thing I really find disappointing about the TF. Was playing a vid for a doc at a meeting the other day, and three of us huddle around it had a hard time hearing it cranked all the way up. The slightest noise of anyone else doing anything in the room just killed it.

Yeh I've had a major drop in left speaker and bad drop in volume on headphones ...... And mine was the official 3.1 update too...... Very dissatisfied

Same problem here. Video is very low when playing avi's or TV Shows Stream. But YouTube app is plenty loud.
Any fixes?

I bought volume + and now it is much louder. Left speaker is still lower volume though. But now atleast I can hear music from the tab.

Bumping this. I'm hoping someone has an idea. It feels like its getting worse. Basically I used to be able to place the tablet on a rack in front of the ****ter and enjoy a show while I pooped, but now I simply can't hear it at all, even with no white noise or anything that could be an issue. So with what you guys have said, I know I'm not crazy.
SOMEONE PLEASE FIGURE THIS OUT. I HAVE NO IDEA HOW.

some peeps already figured out it's a messed up sound config file and you can fix it if you are rooted, was readig through a thread on it here I bleieve lst night. I'm sure it'll be fixed with a software update.

I'm delivering pizzas right now. Do you have a link

I had this too before I sent it in for RMA service.
In fact, I knew about this issue before I even upgraded to 3.1 so I was aware and decided to see if these people were making this up or not. After upgrading I did notice a significant decrease in volume. This was disappointing, it almost made me feel like I was using the Nook Color again.
You're not imagining this. Before the sound was so loud that you could hear it from another room and the unit actually vibrates a bit. Now it's so low it's hard to hear the low tones in anything.
My guess is they messed with it to try to fix the imbalanced speaker issue but ended up messing it up for other people now. ETA for fix is fifteen years. See you then!

Noticed lower volume too after update. take the srs_proceeding.cfg file from my 3.0.1 and paste it to the 3.1 rom and it was louder.

Might the bluetooth routing bugs (where all audio comes out of the ear speaker after disconnecting) be fixed too?
But THAT is wonderful news and what I was hoping for. I have had way too much trouble making my Epic a reliable media player which can multitask, and it's Touchwiz bugs taking most of the blame for the stuttering, in my experience. Has the stock music player changed at all? They did away with some features from the Eclair one which were actually better, which I didn't appreciate...

Looks like it's the same one as Froyo. I use Poweramp so rarely ever touch the stock player.

Thanks. Now can you or someone else test the bluetooth routing? (To test, play something through stereo BT, then switch to voice headset mode on another device by placing or taking a call, then see after you disconnect both devices if media audio is routed incorrectly through the phone ear speaker like it is in Froyo.)

Audio is routed correctly. I just played Pandora in my car over Bluetooth for about 30 min, placed a couple of calls over Bluetooth, and then placed a call when I got home. All worked great!

Was that with the Ec05 modem or the ef02 modem? I get fairly bad battery drain while at work. From the reports that I've heard, it sounds like the ef02 modem has greatly increased signal strength.

[Q] Any volume booster that works w/ 4.2

One criticism of my N7 is that the max volume is too low. I am hearing impaired, but don't have this issue with any other device I use. Whether the speakers or headphones, it is just too low. I think I have tried every free volume setting or boosting app on Google Play and none of them seem to do a thing. My device is rooted with the stock 4.2. I am not particularly interested in loading a custom ROM just for this, but if that is the only solution I might. Any suggestions? Thanks.

Don't do it. I blew my speakers with a booster app.
A better solution ( and with better results ), is to get a bluetooth external speaker. A friend of mine has one of these, and I was surprised by the
amount of volume coming from it in a 20 by 20 room. and he only paid 30 bucks for it.

Youre lucky! Or maybe I am doing something wrong.
The volume through headphones while watching movies using the Google Play Movie app is so low as to border on unusable. Unless you are in a very quiet environment, my experience is you can barely hear the dialogue even at max volume.
Wish there was a way to fix this, as watching movies on airplanes is a primary reason I bought the Nexus 7 and its quite poor for that.

I'm in the same boat. With 4.3 installed headphone volume is limited to 50% on movie/music playback, No warning ever pops up, and all the "audio booster" apps say they only work with Gingerbread.

Extremely low in call volume. Files to edit?

I've been running OmniRom with PA full modular gapps for a while. Currently on 03/05 nightly w/Franco 203.
I use Viper4Android to adjust my headphones and speaker levels.
I have been having extremely low in call volume since 4.4 and I can't figure out why. No one seems to have an issue. I've played with adjustments in Franco's app as well as settings in Viper but it doesn't help. My music sounds great though and voice calls put on speaker are very loud and clear. It's just the handset speaker that's really low.
Previously on my Sensation, I could make edits TPA2051_CFG_XC.csv that would help. And in the Nexus 5 forums I see you can edit mixer_paths.xml to help as well but when I look at the Nexus 4's mixer_path, there isn't a line to adjust handset volume.
Is there a file I could edit to adjust my in call volume? Or any other way to fix this?
Edit: Forgot to include, I use hybrid radio 33-98 for LTE. I've tried other regular and hybrid radios as well and that hasn't helped.

I wonder how helpful this would be for you, but I faced problems with in-call earpiece volume. I had to connect my headphones, call a number, maximize the volume, remove headphones and re-test the volume without headphones. Apparently, I had noticed that it mixed settings of both the profiles - with headphones & without headphones.

Just tried it a few times. No go for me. Volumes for with and w/out headphones are at max. I tried lowering one and the other. Or raising them at different intervals. Still didn't help.
Thanks for trying though.

I actually have the same problem right now. I tired using a flash able zip. Which I have no idea where it is now but all it did was completely disable touch for me. I never tried ViperX but I'll keep snooping around and see what works for me and let you know

Nope. Sorry. I don't think many people are having issues. It might be hardware related but I haven't done a full format to test anything new out.
I update to the newest nightly like once a month and I don't make very many calls so it hasn't been detrimental to me yet.
I haven't seen anyone bring it up in the Omni thread though so I'm certain either a clean start should do the trick or it's hardware related and you'll need an RMA.
Hope you find a resolution for your issue! I'll definitely post something here if I ever figure it out on my end.

Same issue here. Occasionally I've fixed it between kernel or Rom flashing, but never found out what I did to fix and when I'd flash again it would go back to bad quality again. Sometimes I have to stick a finger in one ear and press the phone hard into the other ear to hear anybody

I'm a bit hesitant to flash something for the S3 onto the N4. Plus, the file in that zip you're referring to isn't one that's contained on the N4 in that directory.
Thanks for noting, though. Maybe I'll backup and try it to see.
