Every since I got this phone, a week after the release date, the wall charger seems to make a high pitch noise when the streak is plugged in. It can only be heard while my ears are directly to the side of the charger, not in front. My bed is about a foot away so I hear this noise quite often. If I unplug the streak the noise instantly stops.
I'm just curious if 1. It's safe and 2. if anyone else is having this same problem.
That is usually caused by a vibration in the transformer coil in the brick.
It is harmless, but annoying.
Or the flux capacitor
hitting it with a slipper may help, if it hisses poke it with a stick.

I noticed this morning a strange hissing noise which at first I thought was coming from the phone. This was when I was using the phone whilst it was plugged into the mains charger.
I removed the cable and the noise stopped. I plugged the phone into a USB port on my PC and there was no noise this time. So I checked the mains charger that came with the phone and sure enough the noise was coming from there!
It almost sounded like there was a fan inside, a very similar noise.
Has anyone else experienced this or can you recreate this?
It also happens to my charger, you can feel comfortable there are no problems

I do not have this charger but from your description it sounds like normal switcher noise.
The charger likely uses a switcher for dc-dc conversion. When not well designed they can have an audible noise. Usually it is not a fault and no reason to worry.

Thanks for the info guys
i hoped i finally got rid of that noise with a new phone, but my note 2 charger makes noise too.
just like my LG O2X charger and Galaxy Tab 2 7" charger.
yet all my other chargers are capable of being perfectly silent.
it's loud enough to give me trouble sleeping, and i'm used to sleeping next to a noisy PC.
I don't have a Galaxy Note 2 yet, but my original Galaxy Note's charger makes noise, as well. I believe because it has a high mAH recharging, because I use as an extra charger an old blackberry charger (with a long long cable xD) with only 500 mAH recharging power doesn't make any noise. I don't know if it has anything to do with how much voltage is flying through the charger has anything to do with it, but:
*Samsung chargers make noise.
*Other chargers I have don't.
All the chargers since the SII's have emitted some noise when there is no device plugged in. I don't really mind honestly.

Using nokia phones since 2002 i have to say most of them make that sound, dont worry
I got my SGNII at the weekend, and I have a very noisy charger, to the point where, as it is close to my bed, it wakes me up when its finished charging. However its only noisy once the phone is fully charged. Unplugging the phone once charged means the noise stops, but it also means my phone has been running on battery for 6 hours before I get up.
I think I will switch to a different USB charger that doesn't sound like a mouse being tortured
No Problem
Never faced this issue ever. Maybe faulty chargers i guess
alot of engine noise and hissing noise even when car is off
its a nexus 7 timurs rom, sound going from nexus via 3.5 tapped into factory cd changer any suggestions?
Ground loop isolator.......
I just solved this problem in my own installation. After some searching around, I ended up deciding on this:
http://www.amazon.com/gp/product/B001EAQTRI/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1
It's a good price, free shipping with Amazon Prime and completely eliminates the alternator whine you're experiencing.
Thanks i ordered it from my experience in car audio ground loop isolator a while removingr whine also make the sound dull
Maybe i am wrong but it doesnt seem like a proper solution
Maybe grounding usb power? Or the 3.5 mm jack on the nexus to the cars body?
Who said you had to use one in the audio line?
If you know what to look for you can isolate the noise in the power supply line itself.Something like this. Now the real question is why is it hissing even with the vehicle off. In reality it shouldn't do it at all but nothing is ever perfect and trying to track down a ground issue can be more trouble then it's worth. Do you have battery drain issues? or low charge or possibly high charge while driving? Wondering if you have a possible problem with the voltage regulator in the car itself. When they go back they can actually cause a draw with the vehicle off. Doubt that is the issue but figured I would ask.
And just to be clear as to what you are doing. You are going from the Nexus (headphone jack) to the front of the stock car stereo(AUX input 3.5 jack). Do you have the tablet plugged in to a cigarette adapter or charging by any means via the car? If so, have you tried having it not plugged into the charger to see if that changes anything? Most cigarette or power adapters are not isolated so if you use them you have the possibility of it happening.
My Note 4 (T-Mobile version, obviously) is making a very faint rhythmic beeping sound that almost sounds like Morse Code when I place it on my wireless charging pad. The phone charges just fine and doesn't get hot or anything, but the beeping is very annoying when I try to sleep at night. The beeping stops when I take my phone off the charging pad, but starts again as soon as I put it back on the pad. It still beeps even if I turn the phone off. I am using the official Samsung wireless charging back cover and official Samsung charging pad. Is my phone just transmitting my personal info to the NSA through Morse Code while I sleep?
Thanks,
Jeff
Meth.. Not even once.
My nokia wireless charging pad's wall wart makes beeping/squeeking noises that I thought was the phone at first... might give that a listen if your pad has a wall adapter...
^^ what he said.. I've seen that with quite a few wall adapters so it's not a stretch to imagine it could happen with a charging pad, but put your ear to the wall adapter & see if it's that. In my experience it's old/cheaply made adapters but it could just be a manufacturing fluke with your particular unit
It's definitely coming from the phone or plate (hard to tell which one is making the noise). The wall adapter/cable I'm using are the genuine Samsung ones that came with the charging plate, so they shouldn't be cheap junk.
I'm pretty sure my Note 3 beeped too, so maybe it's just a characteristic of this plate?
It's not your phone, it's your charger.
I have two Tylt Vu chargers and they BOTH make very faint beeping/whining noises when charging my phone, plus the wall adapter makes a constant whining noise, too. It's just ****ty parts used in the chargers, nothing you can do about it.
Hi.
I am finishing installation on my Nexus 7 in my car. I use the DAC Behringer UCA202.
There is a constant and strong noise... I was reading that it can be by charging tablet...
Please, anyone can help me?
Thanks
I was reading about this. It seems problem about ground while the tablet is charging.
Some solutions...
USB filter
RCA filter both, seems that there is a loss of quality of sound.
and any other?
Experiences???
Hi, it's a ground loop issue , i've installed my nexus 7 in my car, i removed the battery from it and use the 12v plug with a 12v to 3.7v converter, to get ride of the hum noise, i had to diy a ground loop isolator for the audio jack (but you can buy them on the internet), the hum/buzz sound is now gone.
The quality is good but the real issue is that i lost some of the bass, i don't remember clearly how much, i should try without it tomorrow to compare again, but i still enjoy my music .
The other possibility is to use à dc-dc isolator supply, but they are expensive (+100$)...
Hi, ground loops car caused by different potentials because of ground points that aren't the same and current flow that is picked up as noise.
My suggestion would be try an isolated 12V - 5V power supply. Those shouldn't be expensive and you can likely find some on eBay. There's a very high chance that will resolve it permanently.
Just needs to be capable of the current draw for the tablet in use & charging. If you're also using a hub and so on you could add second power supply as well.
i toyed around with passive usb isolators off ebay. cant tell if sq is any worse other than the immediately lowered noise floor with the hum gone.
As Marty mentioned, the problem is that there is a voltage potential difference between the amp's ground and the ground you are using with the power to your tablet. The passive power isolator/filter is easy solution if it works well enough for you. It won't deteriorate your sound quality, except that it may not fully eliminate the noise. A filter in the audio cable can cancel the noise, but it will also cancel certain frequencies in your music and affect sound quality. The "most effective" solution is to physically connect the amp ground to the ground you are using with the power to your tablet. That requires getting under the dash, finding the ground wires in question, and jumpering them. Or something similar. Hope that makes sense. But if a passive usb power isolator does the trick for you, then that's the "easiest effective" solution.
There are line-level (RCA) ground loop isolators that have excellent sound response, but they're not the cheap ones you'll find in a stereo shop or electronics store. They're $50-$100 but you can find them on eBay at times.
Jensen and I think 1-2 companies make some with great fidelity. But if the USB isolator did the trick, that's excellent. The ground is the problem, after all.

I did this, bridged the tablet ground and headunit ground together. It reduced the hiss, but it’s still noticeable especially when the engine speed is high.
I guess the next stage is to try an isolated power supply!
Just a couple of minutes into listening through the earphones that came with the box, the connecting adapter starts to heat up like crazy.
I hope this is something that can be fixed via an update or something.
After the last update, my USB-type-c to a 3.5-mm adapter and my headphones stopped working. I'm waiting for the next update
I've had no such trouble with the included earphones.
Mine gets warm but not too bad.

Mine gets hot too. However in my case it is the cable issue. I can clearly hear noise and cracking sound when the headset is plugged in. I have to keep the cable straight to avoid overheating.
Anyone else has this issue? It is not getting hot when simply plugged in, but when I listen to a book or a song, it gets dangerously hot.
Same here, it gets hot and the cracking noises/static in the background are present too.
One weird thing : It is a Type C reversible, so if i plug one way is hard to even stay connected, but the other way it is quite acceptable.
