I understand what you are saying about waiting. I just popped in a 32 Gb SD card and it is about half populated now with 12 years of images and tons of my favorite mix of MP3 and a few higher-quality wav-ripped CDs.

I can only test smartphones in the Ottawa/Canada area ... at the mere charge of a Tim Horton's coffee and a muffin or bagel with extra cream cheese :p
[Galaxy S 4 Q&A, Help & Troubleshooting] trenzterra:
Think someone flashed a custom kernel earlier which didn't solve it. Though someone installed FauxSound and played with the gain settings that apparently solved it, though it wasn't very clear. If you're flashing a custom ROM maybe you could try purchasing FauxSound and see whether it works at different gains (do report back with your results!)

Tried some bassy music out on my s4 running omega v2 and everything is fine, no hissing or crackles... Using beats pro (don't laugh I won them in work) and power amp. I used the adapt sound setup before using them so the sound was more to my liking than normal...

Haven't got any other headphones to try but it's sounding like an impedance issue to me...
[Galaxy S 4 Q&A, Help & Troubleshooting] gavinfabl:
That's just ruined my day. The JVC are my new headphones I am getting soon. The S4 is off my radar now. :(
[Galaxy S 4 Q&A, Help & Troubleshooting] olaf63:
Finally I Went to another shop and tried another Phone. Perfect so I asked to buy a new one after a test. The out of box one Perfect too. So now my first one goes to service and after on sale.

I think now the first batch was faulty but now is safe to buy. The last three S4 I tested where all good.
[Galaxy S 4 Q&A, Help & Troubleshooting] tyoung88:
Yes the HA-FXZ200s are amazing. Still boggles my mind they were able to put 3 woofers in an ime. Tested some more and for the most part anything below volume 11 sounds fine but most songs at 12 and above have serious clipping. Stuck on bluetooth audio for now until this gets fixed.
[Galaxy S 4 Q&A, Help & Troubleshooting] gavinfabl:
Let's hope the reports of newer batches being ok is correct. I could use my Samsung hs 3000 Bluetooth but would rather not.
[Galaxy S 4 Q&A, Help & Troubleshooting] marci4na:
sorry but i can't understand very well english. so there is a problem in music quality upon a certain volume in s4? isn't it?

and some headphones are ok and others don't.

i have sennheizer cx300 are they ok?

you think is a software problem or hardware?

samsung is informed about that?

thanks
[Galaxy S 4 Q&A, Help & Troubleshooting] badenglishihave:
If you are looking for a good place to evaluate headphones that you own/are going to purchase and use with the GS4, I suggest visiting www.headphone.com.

They have performed many different types of analysis for various headphones and one of them is a graph showing impedance across the frequency spectrum. Useful if the low-impedance evidence cited in this thread is anything to go by.

And no, I don't work for headphone.com :D
[Galaxy S 4 Q&A, Help & Troubleshooting] Jensigner:
Yes there is definitely an audio problem with the S4 that many users have reported. It occurs with low impedance headphones (typically lower than about 15 ohm or so). Since most headphones have an impedance that varies considerably with frequency, it is really difficult to know without actual testing if headphones will have a problem, but many have reported no problems with higher nominal impedance headphones (over ~ 20 ohm). Some is suggesting that this might be a problem with an early batch of the S4 but I think it remains to be seen. The CX300 are nominal 16 ohm so they could have a problem since it is fairly low. Probably a hardware problem.

Tried a few more I9500s today with my XBA4 and all were fine...actually the sound was awesome!!!
[Galaxy S 4 Q&A, Help & Troubleshooting] NZtechfreak:
To those reporting there is/isn't crackling can you please mentioned whether it is the i9505 or the i9500?
[Galaxy S 4 Q&A, Help & Troubleshooting] droidrob:
So it is just the i9505 that has the crackling issue? That is extremely annoying for those of us who don't have i9500 in their country.

I really hope that this can be fixed with an update because what's the point of me getting an exchange if it will have the same issue?
[Galaxy S 4 Q&A, Help & Troubleshooting] NZtechfreak:
So far I think the i9505 is the only one definitely confirmed with the problem, sounds like i9500 isn't affected as per the comments above. I have an i9500 also now, but no IEMs of low enough impedance to unmask the problem, awaiting some UE600 (13ohm) headphones so I can test the i9500.
[Galaxy S 4 Q&A, Help & Troubleshooting] Jensigner:
So since the SGH-I337 also shows it (same Soc Qualcomm Snapdragon 600 as the i9505), it looks like is is something to do with the different audio processing in those 2 units. However the strange thing is the S3 over here also uses Qualcomm Snapdragon with probably similar audio design. Weird.
[Galaxy S 4 Q&A, Help & Troubleshooting] trenzterra:
i9505? Could you check the Revision FW of your phone (dial *#2222# on the keypad). Mine reads revision 0.2 and has the crackling problem.

EDIT: But then again you mentioned you're using the CX300, which has a flat impedance curve of 16 ohms. It could be that the problem isn't actually solved for lower impedances but the tolerances have increased.
[Galaxy S 4 Q&A, Help & Troubleshooting] olaf63:
I have two 9505 FW. 02 and tested another two . of all only mine first has the crackling. I tested also another two earphones but they're all Sennheiser at 16. The fact that my tests showed me that fafaulty units are a minority mybe explain the low feedback to this discussion and was the reason that conviced me to test other units.
[Galaxy S 4 Q&A, Help & Troubleshooting] otacon888:
My I9505 with the problem is revision 0.2
[Galaxy S 4 Q&A, Help & Troubleshooting] ewok666:
I'm using Shure SE530s and can't hear any distortion. My hardware is version 0.2........what version are the new batches?
[Galaxy S 4 Q&A, Help & Troubleshooting] NZtechfreak:
Wouldn't necessarily expect you to hear it with them and their 36ohm impedance at 1Khz (and safely above 24ohm resistance even on the low bound measurements in the bass frequency range).

A plea again please in relation to peoples reporting:

1. Note which version S4 you are using.

2. Note your IEM model and please state its impedance, worth looking at places like Inner Fidelity to get some idea about the impedance over the frequency spectrum since manufacturers tend to state only the impedance at 1KHz).

Without these you are really muddying the issue rather than clarifying it.
[Galaxy S 4 Q&A, Help & Troubleshooting] jeremy_inc:
I have the Nocs NS400 and have this problem with my S4 as well, have had to go back to using my S3 as can't live with it.

S4 is i9505 HW version 0.2, firmware MDM.

The Nocs have impedance of "16 ohm at 1kH". I contacted Samsung using the contact form on their site, but they just said "maybe your earphones are incompatible" so my complaint hasn't gone any further than some minion on the 1st line, is there somewhere I can add my voice?
[Galaxy S 4 Q&A, Help & Troubleshooting] marci4na:
hello ! i have sennheyser cx300 II.

is 16 ohm.

does anybody have tried them?

thanks
[Galaxy S 4 Q&A, Help & Troubleshooting] Jensigner:
I'd love to know if Samsung actually "gets this" problem yet.

"maybe your earphones are incompatible" is a completely unacceptable response. We know the real answer is "your earphones ARE incompatible" but the reason for that is there is a hardware (almost certainly) design flaw in the output audio part of the S4 processing. The fact that the S3 does NOT show this issue with low-impedance earphones, and yet uses a similar Qualcomm Snapdragon config. should be a clear sign to Samsung that their S4 output audio design (at least for the i9505 and SGH-I337 modeusl) is inadequate. fwiw I chatted (virtually) with Samsung support yesterday and they claim they are passing my test info up their ladded and they stated:

"I have forwarded the issue to our concern dept. to look into the details and fix the issue"

"They will contact you at your email address with the progress of the issue"
[Galaxy S 4 Q&A, Help & Troubleshooting] trenzterra:
Thanks for the input!

I went down to my local audio store and tried the CX300 MkII. Mine does not distort with those earphones too.

This confirms what I thought: Certain handsets exhibit this problem more than others. So perhaps the demo sets you guys tested may have the issue as well, just that with even lower impedance earphones.

I think the Sony XBA series could be used as a suitable baseline. There are IEMs that go lower than the XBA's range but they are few and far between.

But sadly I had to send my phone in again, this time because of a defective pixel and banding lines on the screen. I cannot for the hell of me figure out WHY they had to change my OLED screen the first time.

[Trophy General] yakie47:
Hi everybody,

I have installed on my vodafone SFR htc trophy, RSPL and then HSPL, after that i tried to install some cooked roms by ansar, after the flash process the phone did reboot to stuck in a black screen, pulling out the battery and placing in again the phone now stuck in the bootloader and went from being PC40100 as a Model ID to be like:

SPAR100 SS-BC (4K)

HSPL-1.10.2250.1(112663)

MicroP(LED) 0x09

Touch A1(v10,20)

and everytime i try to install any firmware even the phone's original stock ones i get the error INVALID MODEL ID [244], i've tried also to flash it using a Y-cable and a Goldcard and when i plug the micro usb cable in the phone while this later in the USB HOST MODE the phone stuck forever in CHECKING.., anybody has any idea how to fix this SPAR100 bootloader problem? thanks in advance.

--------------------------------------------------------------update-----------------------------------------------------

it did work the hex editing and i could bypass the invalid model id error, but now i'm stuck in the [266] error every time i try to install some stock firmware, and i get Radio Update Fail when trying it using the Y-cable, and when flashing a custom rom the flash process goes well until the phone reboots to stuck in htc logo with the 7 vibrates, and searching the [266] error they said about it, it caused when flashing a custom rom that erases a partition the stock firmwares use to install their bloatware so i'm trying more custom roms hopping that one of them finally successfully boots the phone, have you any idea what could be done to bypass the [266] error?
[Trophy General] tonbonz:
Sounds like you flashed the HSPL for the Verizon version of the trophy. The Spar100 is a name change so as not to flash roms not specific to the Verizon Trophy. All you should have to do is revert back to OSPL using the HSPL software which should allow you to flash a stock rom. See this post for more info http://xdaforums.com/showthread.php?t=1195647. Hope this helps!!!
[Trophy General] yakie47:
thanks man for your replay, but that's what i get every time i try to revert back to OSPL using DFT RSPL HSPL tool:

-------------------------------------------------------------

[Error Description]:

Invalid ModelID. This means that your phone not supported.

This installer supports only limited number of the phones.

SPARK, MOZART, MONDRIAN, GOLD, SCHUBERT.

If you have phone from this list, but still have this error, please contact with DFT team.

[Info]: USBWorkHSPL.cpp (301)

[Error Description]:

ModelID is 'SPAR1000'. Please report this info to DFT.

---------------------------------------------------------------

any idea how to change that SPAR100 to PC401000?
[Trophy General] tonbonz:
Honestly I don't but if it's a matter of just getting a rom on the phone you can change the model ID in the signed .nbh file to SPAR10000 using a hex editing tool and it should flash. Is it SPAR10000 or SPAW10000? My Verizon Trophy changes to SPAW10000. Regardless, the model ID is right there on the 4th line in the hex editor. Beyond that PM'ing one of the dev's, Cotulla or mwang from DFT, would be your best bet. Since the arrival of WP8 the experts seems to have abandoned this forum and it's just us noobs :silly: Sorry!!!

The bootloader will show 4 characters and only the first 4 numbers of the model ID, like SPAR1000 or P0401000. If you do use the hex editor only change the first 4 but leave remaining numbers as they are.
[Trophy General] yakie47:
man i really appreciate for you your care, i had read about the hex editing in the DFT team's chines forum concerning the same issue i'm facing, and since i don't understand chines it remained not that clear for me what should be hex edited in the .nbh file, and now as you have shaded some light about it i'll give it a try,

I've already tried to PM some developers out there but they don't respond, may be too busy to do so..., anyway i'll try the hex editing thing and i'll let you know the result.

thanks.

Not necessarily a brick if you have clockworkmodrecovery on it. Google how to get into recovery for your device. I would provide links but I'm on my phone. I bricked my Optimus V because I rooted and didn't have a recovery, and tried to factory reset.

[Nexus 4 Q&A, Help & Troubleshooting] 1cewolf:
My 16 GB Nexus 4 arrived in the mail today. The stock ROM pegged its usable storage capacity at 12.8 GB, which is about on par with what I had with my late Galaxy Nexus.

I tried out a couple of different ROMs before settling on Revolt. I installed Root Explorer and opened it up so I could get the superuser dialog out of the way, but I noticed that the storage capacity had magically decreased to 5.67 GB. That's what the phone reports even if I wipe everything in TWRP.

What's going on? Is it something I did, or could this be a bad phone? I sure hope it's fixable, because the CPU is binned at faster... :crying:

EDIT: I'm an idiot. Did a search and going to try what this post says: http://xdaforums.com/showpost.php?p=34906845&postcount=71

The first thing you need to do is unlock the boot loader.

Secondly, install TWRP, I find it much easier to use than CWM.

http://www.youtube.com/watch?v=CKneYkGqp_A

Put the ROM and gapps on your external SD. Boot into TWRP. Back up the stock rom. Wipe data. Then install the new ROM. Then install gapps.

I am sure there is much more detailed threads on how to do this, but that is the quick answer.
