what else has changed besides the phone? the charger perhaps? where do you keep your phone? do you keep your phone on it's charger while you listen to it via your stereo?

I run a satilite radio in my truck that runs through an aux line I installed and I get engine noise for a couple of reasons. My aux line isn't heavy duty and sits next to my firewall and effected by the EMI of my engine. The power cable isn't shielded and doesn't have any in line suppression so it's effect from the truck alternator, no matter how clean the signal is, varries as your engine's RPMs move. I run into the same issues with my phone, all of this is in a Sierra Denali truck with a Bose system and also occurrs in my BMW. So no matter how much you paid for a vehicle, it still can be a factor.

So try an inline noise suppressor, they're like $10 at radio shack and if it doesn't work take it back.

You'd be surprised of the effects electricity and EMI will do to your audio.

Resistor plugs and wires are sometimes a radios best friend......
[AT&T Samsung Galaxy Note I717] troyolson92:
Max phone volume, and phone flat. Then set car to volume and EQ you like. lest distortion this way. Flac is good or even mp3 at 320... But might as well just use flac then.... If you like it loud set every thing to flat!
[AT&T Samsung Galaxy Note I717] Afishl1:
I don't use a charger, I would be open to trying an inline suppressor, but it seems so complicated to installed from what I've seen. Wouldn't I need to start taking the car apart to install it?

To me it seems that there has to be a possible software fix as like I said before, pushing the back button (which doesn't make a noise) temporarily silences the engine noise for a second or two.

[AT&T Samsung Galaxy Note I717] dakleenupman:
This issue is phone related. In fact, there's multiple threads already on just how poor the audio engine is. I can say though, I have the same issue but only real bad if I'm charging while playing music. The charger creates a ground loop and causes the engine noise to transmit through the speakers. If i remove the charger, it goes away.
[AT&T Samsung Galaxy Note I717] BlkSquad:
You could also look into a ground loop isolator. I've had to use one in previous vehicles and they are quite simple to install.
[AT&T Samsung Galaxy Note I717] Theoriginalgiga:
http://www.amazon.com/GROUND-LOOP-ISOLATOR-3-5-APPLICATIONS/dp/B001EAQTRI

they're usually inline. this is what I found on amazon, I'm sure your local radio shack would happen to have something similar.

Exactly what I meant, I think I called it by something else. Everything in electronics and in computers have 50 thousand names :)

To OP: This may or may not work, some people say it's a software thing, all I know is that when I applied one to my sat radio it cleared up my noise, but my ears aren't what they used to be. Like I said, try it, the worst is you have to take it back.

What makes me think it isn't a software issue is, that it was mentioned that while switching to the home screen with the music off, the hiss ends for a couple of seconds which I believe that it's because the device turns off it's audio port (as there isn't anything flowing through it and does so to save power). From my experience with my sat radio that if it's off, there won't be a hiss because there is no electrical current flowing.

But again, I'm a computer engineer, not electrical.

@dakleenupman: do you have this issue with other external audio systems? I believe if it was software, it would also propagate to other audio outputs. I honestly don't know because I use pandora from my PC at home and listen to my note very rarely and only on headphones.
[AT&T Samsung Galaxy Note I717] Ray_Banci:
Haha oh man! I think in cars the best audio output by default is auxiliary with the most minimal distortion. Then CD cassette. I'm not sure if its a software issue as much as it is the car itself (not the engine but the cars amp)
[AT&T Samsung Galaxy Note I717] Theoriginalgiga:
Well I know electricity has a certain flow which is generated from the source whether it's a water turbine at a dam, coal powering a turbine or nuclear powering a turbine (notice a trend here :)) Your alternator's design is the exact same as most large scale power sources just on a smaller scale. But the difference on a larger scale is the power ir conditioned to that it maintains the exact modulation through the power grid (within a certain tolerance) to get it to your house. Unfortunately there isn't any such mechanism within a vehicle, so as the rpms increase to rev the engine, the alternator spins as well. This will affect the power throughout your vehicle and with such a large deviation in such a short time span, it's bound to cause issues. All that plus EMI from the spinning metal in your engine, plus your ignition system constantly sparking and the whirling transmission that's usually sitting close to your center console will cause interference. So with the aux system accepting an input from an outside source, if that line isn't shielded there is a good possibility that it's going to be affected.

As for your sources of the lowest distortion. I would think that the aux would be at the end of that list because usually your CD player is connected directly (or close enough) to the internal amp in the stereo.

Additionally if you have an amp. it doe just that, it amplifies so if you a small amount of engine noise, the engine noise will be amplified.

Again, I'm a computer engineer, not an electrical, my base info on this stuff is just work related, not actual schooling.
[AT&T Samsung Galaxy Note I717] Theoriginalgiga:
Haha, nice! so you're an electrical engineer?

Honestly I've never tried another external audio system, at least while charging. I'll look into that. But honestly, any other form of charging would be AC so probably no "noise" from it to interfere.
[HTC Amaze 4G] tintn00:
Hi everyone,

I've rooted and installed custom ROMs and kernels on Samsung phones and variety of Android tablets. This is my first HTC device so I'm a little unsure of my options. I've spent the past week going through many threads using the search but I'm somewhat lost. Can you describe each term and its benefits with one or two lines?

Unlock/lock bootloader? Is this equivalent to installing CWM?

Hboot?

S-on/off?

SuperCID?

fastboot?

And finally, what is 'root' in the context of everything above?

Sorry about the confusion. I've never run into these things while messing around with Samsung phones. ANY help is appreciated. Thanks.
[HTC Amaze 4G] kered424:
It's ok, I was in your shoes a few months back. Here's an explanation of everything to the best of my understanding.

Bootloader - I would say this is kinda like the equivalent of a BIOS on a computer. You can access the bootloader by holding Volume Down + Power when your phone is off. With a locked bootloader, you can't really do much to your phone except for flashing stock rom images. You'll need an unlocked bootloader to root/flash roms. No, this is not the same thing as CWM recovery.

Hboot - The version and type of your bootloader. For example, there's ENG, SHIP, and JuopunutBear. Latest version is JBear's 1.93.2222 (I think).

S-on/off - This property is associated with your bootloader. Most phones come with s-on to "protect" end-users from messing up their phones. With s-off, you get much more freedom to customize your phone however you like, such as flashing your own splash screen, radio, etc.

SuperCID - after obtaining s-off, you can SuperCID your device to flash any carrier's rom you like. For example, an Amaze on the Telus/Wind network can take advantage of TMobile's ICS leak.

Fastboot - I don't have the best understanding of what this is yet, but it is an option in the bootloader, and there are adb commands that use fastboot. I think it gives you the ability to turn off and on your phone quickly? Someone can correct me on this if I'm wrong.

Root - gives you root access/permissions. For example, you'll need to root your phone if you want to use some apps that requires root (4ext, lucky patcher, root explorer)

@XDA Amaze community - If I'm wrong on anything, please correct me. Also, please add anything that I might have missed.
[HTC Amaze 4G] tintn00:
Thanks for your help!

I have one more question. I am currently on CWM, Android Revolution (latest with ICS leak), and S-on. If I want to undervolt or overclock my CPU, will I need a custom kernel, S-off, or what?

On other phones, I'd just need a custom kernal and rom that support overclock. I'm not sure how HTC phones work regarding this.
[HTC Amaze 4G] EclipzeRemix:
same, we need a custom kernal for O/C and U/C to work right

[Samsung Galaxy Nexus] Razer(x):
I've noticed some stuff to disappear slowly from the screen.

I mean, if i keep an app open, i can still see some icons (for example) for some seconds after the app has been closed.

Anyone experiencing the same?
[Samsung Galaxy Nexus] malikadnanm:
That's how amoled screens are. It's normal.

[Samsung Galaxy Nexus] Razer(x):
Damn, close this thread please. Posted in wrong section
[Samsung Infuse 4G] bradbusa:
considering other options for a mobile device. what i'm wanting to know is how can i tell which phones have the best output sound quality? i've grown quite fond of our phones with voodoo. i use poweramp to play music and absolutely love the sound.

i've heard other friends phones that arent compatible with voodoo and they just dont sound the same.. almost like the difference between stereo and mono.

i realize voodoo isnt compatible with newer galaxy devices because of the different chips, but hoping they might still sound as good. thanks for any input
[Samsung Infuse 4G] DaveC1964:
The Infuse has the Wolfson DAC that is why it sounds good.

Look for other phones with that DAC then they should sound good too. I heard the sound of a Samsung Note and to me it sounded rather "flat". That one has a Yamaha DAC.
[Samsung Infuse 4G] J101:
I haven't found a newer device with Voodoo Sound support. Nexus S could work if you're willing to cut specs for Android 4.
[Samsung Infuse 4G] Dani897:
the asus transformer tablet has a wolfson dac. and it does have voodoo support.
[Samsung Infuse 4G] bradbusa:
Are there no other chipsets that have the same audio quality as ours? The device doesn't necessarily have to support voodoo, I'm sure the same effects could be achieved without it..

So..basically the infuse is the "best device" capable of producing this kind of audio quality?

That's disappointing..its really the only reason I haven't upgraded yet. I wonder how it compares to non Samsung devices, out even non Android devices. I'm open to switching platforms and brands
[Samsung Infuse 4G] J101:
I tried a WP7 Titan prototype and was dissappointed. The only other option I've heard of is an iPhone using an external DAC with an amp for your headphones. Too much work IMO.
[Samsung Infuse 4G] bradbusa:
Wow I didn't think the options would be limited to devices before the infuse lol I'm kinda partial to having one device for all my needs. Its a shame manufacturers are slowly drifting towards cost/benefit for the majority:( looks like I'm keeping my infuse.
[Samsung Infuse 4G] FIREONHIGH:
captivate uses the wolfson chip,,yeah not an upgrade,now if cowon and sam would hook up it would be awsome
[Samsung Infuse 4G] slipudatung:
I have been researching this for a long time and nothing I have found compares to a voodoo enhanced Wolfson DAC (excluding line out amps). I contacted Supercurio before deciding on a device to see what he personally has found to give the best sound (I trust his ears) and the response was Nexus S or Infuse. The tw6040 in the g-nexus is "ok", better than yamaha but not as good as cirrus (newer iPhones). Infuse was my choice and still yet to find a true contender!
[Samsung Infuse 4G] Ryanscool:
I wonder how good the htc one x is.... debating running up to the store and testing. Oh wait, its got beats lol
[Samsung Infuse 4G] bradbusa:
ok, so this brings me to my next question.. no suitable replacement currently available from att with wolfson dac.. are there any international devices sporting the wolfson chipset? ex: gs2, galaxy note.. etc.. ? where can i find out which audio chipset each device has? i've been looking all day. i cant even find a site that mentions what chip the infuse has unless i type in " infuse wolfson" but that defeats the purpose, because i already know that!
[Samsung Infuse 4G] slipudatung:
I work at a telco that just launched it last week (and one-v) and it sounds just like the sensation xl. So yea, just beats. Not as good as voodoo and that was comparing both on dre solo hds. But hey, ears are all different so might sound good to you. :D
[Samsung Infuse 4G] slipudatung:
When I was looking for "the one" I was calling around manufacturers asking about their chipsets. The unanamous response was "we cannot disclose that information" so it's all hush hush. I was trawling daily looking for references to teardowns and specs looking for things like "DAC" and "Audio chip". Painstaking but I found the infuse (I live in new zealand) and couldn't be happier. If I find anything as I keep searching from time to time I will update here :-)
[Samsung Infuse 4G] bradbusa:
Appreciate the input. does anyone else know if international versions of any device have a Wolfson DAC or similar?
[Samsung Infuse 4G] xDa.Fun:

[Samsung Infuse 4G] jblparisi:
Have you looked into the LG G2X ? I believe that one has a Wolfson DAC if i am not mistaken.

I personally am going to hold off on upgrading devices until i find something comparable to the Infuse or Nexus S.

Call me crazy but that is one of the reasons, or the main reason I sold my Galaxy Nexus and kept the Infuse 4G instead.
[Samsung Infuse 4G] Ryanscool:
Was the gnexus just decent?
[Samsung Infuse 4G] jblparisi:
I did not spend too much time testing or tweaking it, but right out of the box i can say it didn't really please my ears. I have a decent headphone audio setup in the $800 range that includes a dedicated USB DAC/Amp coupled with a pair of Sennheiser HD650 and the Infuse still satisfies my needs in comparison.

So yeah, to answer your question, decent enough if you don't really have sensitive ears or you are one of those folks that believe beats by Dre is great audio.(Including headphones, or beats by Dre lib mod junk that you see here around the forums, etc..)
[Samsung Infuse 4G] Ryanscool:
I believe its good lol but hate the stock sound with all the heavy bass, i tune it from there. Then to me it sounds good on a good headset or stero system. The best sound that came out of my infuse was in my car with beats installed on cm7, along with voodoo tuning. It sounded amazing (to me and everyone who heard it lol).
[Samsung Infuse 4G] slipudatung:
My ears disagree with this. I too have hd650s and also some grado's but for portable music my dre solo hds murder them for clarity - especially on the infuse. I just use poweramp to tweak the highs slightly and to me they sound incredible for the electronic music I listen to. They shake my head like nothing else. Love it to bits!

To each their own I guess.
[Samsung Infuse 4G] bradbusa:
ya, not all of those dolby phones are on at&t.. not interested in switching carriers. though i do have a pretty big hard on for samsung devices, i wouldn't be entirely opposed to swapping manufacturers provided the device was comparable to a gs2, skyrocket, or note type device.. would need heavy specs, a newer OS and of course a better or comparable DAC to the wolfson in ours..

i just dont know how to go about finding out which phones carry which DAC other than the older phones that came out way before the infuse. grrr!
[Samsung Infuse 4G] FIREONHIGH:
any one know which chip the gs3 uses?ohhh hell yeah http://xdaforums.com/showthread.php?t=1633685 i think im getting this as soon as it will work on tmob
[Samsung Infuse 4G] jblparisi:
Hehe, now i know what phone I have been holding off for :)
[Samsung Infuse 4G] bradbusa:
That will be nice if/when it comes out. Hopefully we won't get another neutered version like with the gs2
[Samsung Infuse 4G] Ryanscool:
Itll be called the skyrocket hd. Anyone ever see any pictures of it? Lol its pretty obvious, almost same styling. It should have the s4, which honestly id rather have then the quad core exynos.
[Samsung Infuse 4G] bradbusa:
s4?
[Samsung Infuse 4G] Ryanscool:
What you mean? the quad exynos will not support LTE, they made that pretty obvious....
[Samsung Infuse 4G] bradbusa:
ya.. idk why i asked that.. i googled it afterwards and found what i needed to know. i'm not up to speed at all on current mobile technology haha

will the s4 be better than quad exynos? for some reason i think no.. dual core vs quad core hmmm
[Samsung Infuse 4G] Ryanscool:
The dual core is latest tech. The quad is last year tech just added another dual core. The new tech is way better, gets better battery life, and the dual is as fast as the quad in everything but games, but its close.
[Samsung Infuse 4G] scuzzbag87:
Have u seen the benchmarks on the exynos completely destroyed everything else on the market
[Samsung Infuse 4G] Ryanscool:
Wow... then maybe nvm. Then again sense hold back the s4 so idj if thats fair (yet).
[Samsung Infuse 4G] bradbusa:
No I haven't, but I'd like to. dual maybe as fast up to a certain

Point but obviously multi tasking will be significantly improved
[Samsung Infuse 4G] Ryanscool:
http://www.androidcentral.com/why-my-dual-core-s4-better-your-quad-core benchmarks arent the selling point folks.... its what the processor can really do. I stopped believing in benchmarks when my cm7 infuse out did my friends galaxy s2 in normal usage everywhere, not benchmarks though.
[Samsung Infuse 4G] bradbusa:
while that was a great comparison, that video did not compare the s4 to the exynos 4 quad.. they compared the s4 dual core to the tegra 3 quad core..
[Samsung Infuse 4G] Ryanscool:
True. Theres not much yet on the quad exynos though.

After being on these forums for a while, I've come to know the 5 main ROMS for the D4.

AOKP

The Arctic

SELFKANG/CM9

Eclipse

I think that there should be a thread that compares each ROM, and that helps people, myself included, choose from these wonderful pieces of software that would best be suited for their likings.
[Motorola Droid 4] nowell29:
If I may, I came from CM7, and I miss it dearly. I also enjoyed MIUI, but always came back to CM7.

I am excited about CM9, but more than ICS, I want some tweakability and theming again. I would love to see CM7 themes.

However, my biggest actual need, is lapdock support. Whatever custom rom supports it will be my first choice.

I just wish I could code to help. Alas, I am not a coder.
[Motorola Droid 4] alex94kumar:
I was more referring to features of the listed rooms in my first post. But theming and such are good things to discuss too :)
[Motorola Droid 4] tliebeck:
Is it still true that none of the ICS ROMs have a working video camera yet due to driver issues?

I'm still on stock, but recent issues with Bluetooth AVRCP being completely broken in both versions of the stock ROM have me interested in taking the plunge.
[Motorola Droid 4] Die Bruine:
It's true. For video to work I guess we'll have to wait for an ICS release from Motorola. Doubt any dev will work on it knowing Motorola will release it.

I for one am a happy AOKP user. Not sure if you would be. Some have reported audio issues with ICS/AOKP/AOSP. At the moment I have no need for Bluetooth audio. Except maybe my carkit.
[Motorola Droid 4] alex94kumar:
I'm perfectly happy sticking on eclipse 1.3.6 right now :) its really fast, and no issues as of yet
[Motorola Droid 4] RideZeLitenin:
Looking for a nice ROM with stable data connection, absolutely love ICS but sketchy data is putting it on hold for now. Gonna try eclipse...
