Hi All,

Per the discussion of this thread: http://xdaforums.com/showthread.php?t=1367120&highlight=usb+amazon+charger&page=3

I bought this Car USB Outlet Charger: http://www.amazon.com/gp/product/B002F0200Q/ref=oh_o02_s00_i00_details

It charges under AC mode, but if I also connect the 3.5mm jack to my cars speakers there is a high pitched noise that increases as the RPM of my engine increases (for example if I put my car in neutral the sound is at the lowest frequency, and if i step on it the sound shoots up).

If I remove the charger from the phone the noise stops. If I begin playing music the noise also goes away. If I stop any playing music then the high pitch noise will return after a brief (~5sec) period.

It's not a terrible issue because it doesn't interfere with playing audio, but it is an issue if nothing is playing and the car speaker is turned on.

Would appreciate any insight.

Thanks,

DL

I have the same issue. It's not the phone, it's your car. You are hearing the alternator noise through the electrical. I have some friends who are car audio installers and what you have is a most likely a bad ground on the auxiliary port. I've tried with 3 or 4 phones with my car and they all do it while charging.

From what I understand there's 2 ways to fix it. Have an audio Installer open it up and ground it properly. This takes time and could be complicated depending where the fault is.

There's also a magnetic shielding thing tthat you can pass your auxiliary cable through which is supposed to be like $5. I've not tried the simple fix yet. I keep forgetting to ask what iit is exactly.
[HTC Rezound] driftlogic:
Well I was thinking it was an issue with the actual charger, not my car...

I've used a blackberry, and itouch before while charging and going to the car audio without the problem (but this was not with the Belkin adapter I linked to).

Just to be clear when you say an issue with grounding of the auxillary port you are referring to the the 3.5mm input, not the cigarette lighter port?

Let me try switching the cigarette port.
[HTC Rezound] rgallius:
Yeah, the 3.5mm port. I've also tried changing chargers and nothing has made a difference.
[HTC Rezound] driftlogic:
so what you are saying is the issue is with my 3.5mm jack even though the noise doesnt come through if the charger is disconnected?

I've never had any problems with other devices when charging and playing audio.

Only with this particular usb charger and my rezound. :eek:
[HTC Rezound] antispiral:
happens to me sometimes too...I just act like I'm in some kind of spaceship as I zoom down the highway :)
[HTC Rezound] driftlogic:
I'm thinking to buy something like this to power my devices, probably a good investment...

[HTC Rezound] glfman:
Had the problem with a Verizon charger, took it back and the new one worked fine.
[HTC Rezound] craigsdocks:
You could try some snap chokes (ferrite cores) they snap around the outside of the cables you may have seen them on some of your usb cables, they reduce interference

radio shack search "snap choke" they have two sizes that fit around the outside of the cable, 5mm and 3.5mm ... they come two to a package, try using them on the power wire and if that doesn't work try it on your aux output wire, they just snap on. you can snap them off if you want to remove them, you can use more than one on a cable if that helps

This is not a fix all and may or may not work but this is what they are designed for, it at least may cut down the noise some but no guarantee's

Once you search on radio shack, read the reviews on them you will see what some people are using them for, they are about $3.00 for 2 chokes
[HTC Rezound] driftlogic:
Thank you for the suggestion. I will certainly take this idea into consideration.

I do think the piece is defective, but the amazon seller only offers a return, and it was only 5$, not sure if its worth the hassle.
[HTC Rezound] V0latyle:
The charging circuit on your alternator has a bad filter. The whine you're hearing is the AC generated...the frequency corresponds with your RPM. Basically, the rectifier diodes are doing what they are supposed to and putting that AC into the electrical system as pulsed DC, but there are capacitors and chokes that are supposed to smooth the current out so it doesn't stress out your equipment. It's possible the charger you got doesn't have a filter either. Ensuring your equipment has a good ground should help, but it may not fix the sound...you'd have to replace your alternator.
[HTC Rezound] Kane5581:
Its ground feedback. Could be anywhere in your car. Could also be the charger but probably not.
[HTC Rezound] ssb13:
I have a similar effect, but fortunately it does go away once I start playing music. I only hear the noise when nothing is playing. I don't engine noise, just static. I know its related to the changing connect since it goes away when I unplug it.

I was thinking about seeing if there is something to impede interference that I can put inline with the cable or on it.

My aux audio was an PAC Audio connection that I installed, and the dock/charger I have is kind of cheap-o, so I figure its just the price of being frugal.
[HTC Rezound] driftlogic:
yes thanks all for the advice and feedback.

@ssb13 yes the sound interestingly stops right before any music plays, and then has a short delay before coming back after the music finishes.
[HTC Rezound] jdaghir:
I suspect a ground loop isolator would solve your problems.

Here's one from Kensington on Amazon:

http://tinyurl.com/6m58v6s

But there are several other makes that probably would work equally well. Just do a search on Amazon for a ground loop isolator.

Check out the comments on the Kensington one and see if the problems sound familiar.
[HTC Rezound] brando56894:
I have the exact same problem! It happens with both the AC cigarette charger and the usb cable I have connected through my headunit. I have a cheap radioshack stereo cable as the connection between my rezound and the headunit, but when I've used headphones I don't seem to notice it either because the music is too loud to notice it or there isn't any interference. So I'm assuming the interference is caused by a feedback loop since power comes in from the charger and then audio goes out through the headphone jack and back into the car.
[HTC Rezound] acerpalustrus:
car charger noise

I purchased and installed an EMI/RFI suppressor from Mouser. It is a 2-piece ferrite cylinder that fits around the USB cable coming from the car charger/power supply. Unfortunately, it made absolutely NO DIFFERENCE in the noise. It is the same type of suppressor that is sometimes installed by the manufacturer on power supply output cables, so I was hopeful that it would work. Guess I will try looking for a loose ground connection.

[
[HTC Rezound] mike.s:
A ferrite ("snap choke," "RFI suppressor") won't do a thing at audio frequencies. You're hearing whine from the alternator. It's worse because you have a ground loop - the phone is grounded by both the charger and the audio jacks. It's probably worse when no music is playing because the phone then turns off the output amplifier, making the output a high impedance and letting the noise be heard due to the ground loop. A ground isolator in the audio line will probably help, but may not completely eliminate, the noise. Why not get a Bluetooth audio adapter for your car?
[HTC Rezound] GrayBoltWolf:
Ground loops suck, at home they can be fixed by breaking off the grounding pin on a power strip and using that. But you can't do that in your car.

I am having an issue, And it seems the phone Bricked on its own. I did a factory reset then had to do a Hard reset. After the phone Starts up it worked for a bit. After adding my Moto Blur account and then my Gmail account it automatically started to reboot. After the Reboot the screen is unresponsive and it keeps displaying a message saying the process has frozed and please force close. I can press the options but i cant use the screen for other functions. What can i do because i dont know what to try next?

[Galaxy Note GT-N7000 General] anonymous572:
Not so long ago I became linux mint user. Many of the necessary programs and games runs without problems in Wine. But I couldn't connect my galaxy note through wine. So I find another way to connect it with odin through VirtualBox. I wrote a small guide:

- Install VirtualBox.

- Download windows xp or windows 7 ISO image install disc. For example, you can download windows 7 trial 90 day from microsoft.com. If you have a disc with windows installer you can use it. I personally prefer windows xp micro edition (250mb).

- Start VirtualBox. Add virtual machine, choose your ISO image or real CD-ROM if you have disc. Install windows with the recommended settings.

- When the installation is complete, and windows will boot to desktop you will need to install drivers. Connect USB flash with drivers to your virtual machine or create virtual network disc to linux and drag these drivers (mirror1, mirror2) to windows.

- Intall drivers.exe in virtual machine.

- Move odin to your virtual machine same way. And start it.

- Reboot you galaxy note in download mode and connect to usb. Press USB indicator in the bottom menu of virtualbox and choose your samsung connection.

If you are doing everything right you will see this:

You can also try Heimdall. It has linux port.

Kies should work fine same way.

I've been searching for a few days now with no luck. I'm looking for a Phone app that has your sms inbox included.

Ultimately I'd wish for the default Android Phone app, axe the "Favorites" tab and replace said tab with a shortcut to your SMS inbox.

Are there any apps out there that do something similarly? My reason for looking is purely for screen space efficiency though an all-in-one app seems like a good idea for consolidation since both functions use your carrier's cell service regardless...

I called AT&T and they said that they don't have the unlock code since they don't even sell the device, but that it works on sims outside the US.

Can anyone verify this?

Most customer service representatives are pure idiots .... Nexus S is a Google phone , so it's factory unlocked to any SIM card you use with it(you may or may not get 3G on other networks depending on the other network 3G frequencies , and if the forgein network has 3G on 900/1900MHz it will have 3G on this Nexus S)..

Hope this helps..
[Nexus S Q&A, Help & Troubleshooting] dannypp:
Well I went to tmobile and the guy put in a sim into the phone and the phone got no reception nor did it seem to recognize the sim at all.

So it seems that it isn't unlocked.

I tried putting in this code: *#7465625#

Its supposed to tell you if the phone is unlocked or not, but nothing happens, it just says: Connection problem or invalid MMI code.

I don't need it to work on tmobile, but I do need it to work on foreign simcards. And I saw on other forums that for some people it worked on tmobile and others it didn't so there doesn't seem to be any clear answers.
[Nexus S Q&A, Help & Troubleshooting] mahanddeem:
you have another issue here , check your phone
[Nexus S Q&A, Help & Troubleshooting] dannypp:
Thanks for the response.

What do you mean by other issue and how should I be checking my phone?

In any case, I put in a simcard that my brother gave me which I believe is from Mozambique on a carrier Vodacom. It asked for the code of the sim when I put the phone is as always, and so I got in putting in 0000.

It then showed no connection to anything whatsoever, also as always.

Keep in mind I did have wifi on.

Then all of a sudden it asked me to update my phone and install something. So I just said yes and it updated and rebooted.

All of a sudden I have bars here and there and it recognizes that tmobile and AT&T are in the area. I also saw I think at the top of the notification bar when I pull down the notifications tab, it said Vodacom. Of course I get no reception whatsoever but that is expected, this sim was a gophone sim in Mozambique.

Does this mean that its unlocked if it is recognizing another sim, even though no confirmation of reception? I plan to try again with tmobile now and perhaps make sure I have wifi connection while doing so and leave it in for longer.

Thanks and please let me know if you have any thoughts.

IF it doesn't work with tmobile again, I will try taht, and I will also try to learn what an apn is.
