Well, I got the Samsung dock, and as much as I like the E4GT, the dock is terrible. Here's my experience:
1. There's a ton of line noise when the phone is docked but nothing is playing, just like with the Epic. I'm using the OEM charger, but that's not the problem--using the same charger, the Photon's car dock is absolutely silent. Samsung must be using some cheap electronics in this thing, and it's simply horrible. (Sorry for venting, but seriously...)
2. The software isn't nearly as seamless as the Photon's either. First, on the Photon, when you dock an app starts that essentially takes over the home button. That means you can move back and forth between the app and the home screens easily. On the Samsung, it seems like once you leave the Vlingo app to, say start a radio streaming app, you can't get back to the dock mode. At least, not without unplugging/replugging the dock connector, but that's extra wear and tear. If I'm wrong about this, please let me know.
Then, the Photon app allows for 4 custom apps to be assigned. That provides a great deal of flexibility, and again it's easy to go from one app to another and then back to dock mode.
Overall, the Samsung car dock experience is nowhere near the Photon's. Motorola really did a great job with this, and Samsung makes it look like they gave actually using the phone in the car zero thought.
What's everyone else doing to make this experience more usable? I'm still choosing between the Photon and the E4GT, and the car dock definitely is a mark in the Photon's favor.
1) Use bluetooth audio streaming for zero noise. Are you connected by the dock's audio out jack, or the GS2's headphone jack? I noticed better sound with the latter, but using BT is easier and sounds so much better.
2) Ditch Vlingo for CarHome Ultra. Extremely customizable and lots of great features, including up to 18 app shortcuts and auto-switching day/night themes. I love it.
You could make a profile in tasker that recognizes when the phone is plugged into a dock. Or you can make one for when it is rotated in landscape and plugged in. Then, you can enable an app to run, or have a list of apps that you can choose from. This is what I do with my phone and I don't even have a dock. It's awesome how much you can do with tasker!

I'd love to do that, unfortunately my car doesn't have Bluetooth audio. And I'm going from the dock's audio out to my car's AUX in. That's an idea, using the headphone jack, but I hate adding wear and tear.

Thanks again for the tip, that app rocks. In fact, it's better than the Photon's car dock app.
Now all I need to do is find some way to clean up the line noise and I'll be a happy camper.
Go to radioshack. Ask them for a ferrite core. Should be a ring of "ferrite" or iron. Make sure it's big enough to put the plug on your audio cable through. Push it through and wrap it around a few times and see if that helps. Also, running a separate hot lead and ground from your car battery to the cigarette plug you use should help. But the ferrite core should be easier/cheaper

call audio routing
Has anyone else been able to get call audio to route to the output on the dock? media audio comes out the port so I can hear that on my cars speakers but when I make a call it comes out of the phone speaker....
So, I've tried a variety of power adapters, USB cables, and audio cables, and the line noise remains. I'm going to try the ferrite core around the audio cable, but I don't think that's the issue--if you unplug the unit from power, the line noise disappears. So, I think it's just bad circuitry in the dock.
One would think that Samsung would have received complaints about this with the Epic dock (at least) and would have fixed it. Motorola managed to make a dock with excellent sound quality and zero noise, so it's certainly possible.
Otherwise, the E4GT is decent in the car with that Carhome Ultra app. Although, that doesn't really help with my decision between the E4GT and Photon, because with the Photon I could have the same dock app but also outstanding audio quality.
I can only assume the noise you are hearing is due to a Ground Loop/Hum.
It has to do with the fact that your power source is grounded to a different point than the stereo/speakers. the hum you hear is the difference in voltage's between the 2 grounds being represented as noise in the line.
for instance. I recently installed a new head unit in my truck, the unit has an AUX in and a USB port. If i plug my E4GT aux cable into the stereo and plug the USB charger into the port on the stereo - NO Noise. However, if i plug the phone to charge in another outlet (say, the cig lighter) then there is Line Noise everytime. The same principle applies when plugging your phone audio jack into any electronics.
Hope this helps shed a little light on the noize.

I hear you, except that I have two different docks that display entirely different behavior. Actually, I have two docks from the same manufacturer (Samsung, for the Epic and the Epic Touch) that have significant line noise, and one (Motorola) that does not. Note that these are all plugged into exactly the same power adapter and outlet and using the same USB and audio cables.
So, you'd need to account for the fact that the Motorola signal is perfectly clean in precisely the same circumstances while the Samsung's signal isn't.
I believe every word of it.
From what I know about Ground Loop Hum there are many weak links in the chain, and certainly some products behave better than others. The problem is still most likely the Ground.
One possibility would be that the manufacturer of the Moto Dock has included an isolator in the power supply line (or even in the audio supply line), and the manufacturer for the Sammys didnt.
My experience in this subject is with my Laptop/DJ setup making noise when plugged into audio equipment. when the power supply was plugged into the lappy, 60hz hum. Unplug it and it goes away. More than likely the problem was inside the computer or the power supply was just poorly manufactured as other models may not have the Hum. In my case i purchased a small isolater solved the problem. It may be possible to find one for a 12v car electrical system.

I actually hooked up an old RadioShack groundloop isolator to the AUX cable, and it got rid of the hum.
Something like this should work fine: http://www.amazon.com/GROUND-LOOP-I...QTRI/ref=sr_1_2?ie=UTF8&qid=1322958491&sr=8-2

Well, the salient point is that Samsung uses inferior components. It's possible to make a device that doesn't suffer from the problem, as Motorola has shown.

most times I've had line noise, be it from improper grounding or from cellular interference (namely from ground issues) the ferrite core fixed it. If it doesn't, the power isolation will. The reason the USB Ports on the head unit doesn't create line noiseis because it has isolation circuitry built in. The core is cheap. If that doesn't work, isolate power.

Okay, in the latest saga with the Samsung car dock, I noticed this morning that when I received a Bluetooth phone call, the TuneIn Radio audio I was playing didn't stop. Or, rather, it did stop once the stream buffer ran out, because I was on 3G and of course 3G data isn't available during calls.
Is this really how the Samsung dock works, that audio doesn't give way to Bluetooth calls? Or is that perhaps the CarHome Ultra app?
Still a bit frustrated with this aspect of the Epic Touch. The Photon's car dock works perfectly, including muting audio while on a Bluetooth call.
Grrr. I know, I know, if I like the Photon's car dock so much, why I don't I just stick with that phone... But seriously, Samsung, how hard is it to get this right?

I wonder if it might be the phone or the application. When listening to Sirius/XM radio without a dock, and I get a phone call, the radio keeps blasting away.
You don't stick with that phone because this one is superior in every other way. Its a minor issue. Why would you even have the aux input selected when there is no music playing? I have the noise too so I get it but ...yeah I just change the input when I don't need it.

Sent From My OneX Beast Using ViperX
mine does it sometimes when charging, some people say using a different charger will fix it, but it hasn't for me..
saying that, i think its my 'dirty' power supply in my house, its an old house and electrics have a lot of interference, the problem doesn't happen to my phone whilst charging at work for instance.
I've experience this and these are my thoughts on this, although this wasn't specifically for the oneX:
Incompatible charger
-using a different branded charger, class A replicate.
Power supply/plug:
-I can't be sure of this I'm pretty sure every other gadget should have blown up if this is the case
Generally you lose control of your screen I'm thinking this would be hardware faults or just incompatible voltages.
I'd advice you to take your device and charger to the place where you bought it and test it there, or find an electeician friend

I think ill take my charger (the one that came with the phone, but presents the problem when home) to work, and see what happens.
Rather than it being too high a voltage from the plug etc, I think its the interference/noise on the power lines, my speakers (in the same room) have this buzzing sound when using an analog cable, I need to use optical to eliminate the sound. Problem never happened until I moved here, turns out the speakers should be shielded against this (they are z5500) but its on the net that others have the problem also.
All the opinions lead to interference on the power supplys in the building.
Another example in the same house I'm in:
Couldn't run a long 20 meter ish phone cable up the stairs, as the speed of internet deteriorated from 20mbit to about 2mbit. It was fine at my old house with speeds.
I ran an Ethernet cable upstairs instead, just the standard utp, its the twisted pair that stops crosstalk, which I was hoping would eliminate the interference from the power. It worked
Anyway..
This leads me to think its another problem with this phone, as charging any other phone with the same charger, in the same house, same socket even, doesnt present the problem. Hopefully something software is able to fix.

when i plug my phone into my car to play music its fine. when i use my car charger and play music at the same time tis fine but the second the music stop i hear a static noise from my speakers (which is attached to my galaxy)
this static noise is an imitation of whatever my car is doing at that moment (if im reving the engine the static will resemble the revs, same with turn signals)
anyone else experiencing this problem?
It's feedback from the car electrical system. Usually a bad alternator ground or corroded battery cables, or even the cables going to the starter.

I'm assuming it isn't a stock deck? Check your ground and of possible try a new location.
All in all though, Androids micro USB is a horrible horrible connection. Every Android phone I have ever owned makes some sort of hissing sound while charging and listening to audio through the headphone jack. Even the Google Nexus does. But the iphone doesn't. Go figure.

On my i747m, I could not use the USB port to listen to music while I was charging via cigarette lighter. There is a definite design flaw. I bought an Ibolt dock and am not able to use it the way it is intended. Even when I wired it myself from scratch (I'm a sound tech) it failed.
Not only does it make white noise and static between songs, but there is some kind of GATE that kicks in 1 or 2 secs after any music pause....it cuts the noise in half but it still remains...and the act of cutting, is an irritant in itself. Further more, even when your playing music, the NOISE is fighting for sonic real estate. I can hear it. I am trained.
So for me, I am running the audio out of the headphone jack. It's 98% better but still not 100%. I don't get the classic REV issue...which has to do with grounding and/or cable shielding. But, if I was you, I would go to The Source store and pick up a Ground Isolator. They have one specific for car issues like yours.
Its a ground loop.

It MIGHT... be a ground loop.
It might NOT.
Read my post #7.
If your using USB audio, there is an internal design flaw NOISE issue independent from any GROUND issues. (at least with my i747m) I can reproduce the machine like noise in the car, on a desk dock, on a separate stereo system. The Ground Loop isolator did not help my issue but it's worth trying if you get the hum/car interference noise from usb and/or headphones.
So ive got to say this phone has been pretty much awsome for the past 24 hours but I have found its first major short coming wondering if anybody else is having this issue.
SO here is what happens. I happily plugged my note 4 into the aux audio jack in my car and then I plugged it into the car charger. That is when I get this really annoying electrical noise through the stereo system in the car. So I was like hum that is weird my note 2 only did that if the jack was not plugged in all the way. Well when a sound on the phone plays the electrical noise goes away completely and I hear the sound or song or whatever audio is playing crystal clear. Then as soon as no sounds are playing as if the audio card in the phone is not being used its like it shuts off and lets all this electrical noise coming through the charging system of the phone. Then if say a txt comes in the electrical noise sound goes away the alert plays then after the alert plays the electrical noise comes back super annoying. Can hear the alternator in the car through the noise as well. Make me wonder if it is a software issue of some sort because the noise goes away totally whenever any program takes over the audio driver and plays something through the sound card.
Anybody else have this issue? Try it if ya have not would be interesting to hear reports on this. I do not have bluetooth in my car so could not test it. I always raise the phones volume all the way up when plugged into the aux jack so I have more preamping to the stereo.
Thanks
Haven't tried on the note 4 yet but I did have this same issue on the note 2. But it was more of a white noise. Very low almost TV static noise.

I've had this issue with multiple different phones - I don't think it is the software exactly.
The only time that would ever happen to me is if I was using my aux cable AND had my normal AC charger plugged into it (using an adapter for the car that turned the "smoking thingy" into an AC socket.) If I used an adapter for the car that just gave me a USB port to charge it through only cable it would never happen.
And this happens consistently - haven't tried with my note 4 though yet though.
Try it without your charger plugged in.

I agree without the charger plugged in there is no noise at all. But it is strange that the grounding loop problem only occurs if software is not playing any audio at all. It literally goes away when something plays audio I can hear it go silent then the audio plays then there is another 8th of a second of pure silence then the noise starts again. Or say you are listening to tune in radio or something and a notification comes up. It will pause the radio program and then you will hear the noise for a split second then a sound will play silent again then split second noise then the radio will resume playing. So between the hand off of the two audio programs playing a sound you hear the noise really weird.
I agree the AC adaptor made noise for me as well on the note 2 plugged into an inverter. But this is just my normal 12 v adapter that never had a problem with the note 2. Will be interesting to hear what more ppl say with their 12 v adapters.
My power adapter above 1 amp makes a lot of noise. Had a 2.x amp for quicker charge. Had to revert to 1.x amp charger to reduce noise.
Does the Dash Charger make noice also, is it Normal? Thx!
Just checked but No Sound at all.
Mine does - a very slight buzzing whirling noise...have to have ear less than a foot away to hear it. Not sure if it's normal, but my Op2 adapter made pretty much the same noise.
Normally i would see cheap condensators placed.

In my personal experience I have noticed an extremely high pitched noise from pretty much every mobile phone charging brick I have ever used. Nothing to worry about.
Mine has always been 100% silent, but if you're getting some kind of noise out of it, try plugging it into the power strip, or plug it in at a different location and see if it stops. It might be that the power coming into your house is "dirty". I used to build pro audio studios, and we always had to use power conditioners due to the power coming into the location giving producing substantial noise in the lines, both analog and digital.. A lot of it has to do with slightly out of phase AC current, and when it's switching to DC in the charger transformer it can make noise at the front end of said transformer. Also, the dash charger pulls a significant amount of current to be transferred so I can imagine some noise would be expected with unconditioned power going into it.
If it's annoyingly audible I would plug it in elsewhere and if it still makes the same noise contact OnePlus and get another one.
So Many people facing same sound issue inside the charger,its normal
Mine is silent and if the sound being emitted by your charger is like a buzzing one is extremely low then it can be considered as normal but if its even audible during normal room sounds then you should get it checked.
If you unplug your charging cable from the phone before unpluging your charging brick from the wall outlet, then some "charge" may remain in the charging brick. Just remove the charging brick from the wall outlet first, wait about 3 seconds for the remaining "charge" to transfer from the charging brick to the phone, and then unplug your cable from the phone. By doing these, there is no remaining "charge" in your charging brick and it won't make that buzzing noise. That buzzing noise occurs on all of my other charging bricks as well (for samsung tablet, lenovo smartphone, oneplus 2). Of course, if the charging brick makes that noise, just plug your cable in the phone (without plugging your charging brick in the wall outlet) - this will transfer the remaining charge from it to the phone and the charging brick will stop making that noise.
