whenever i plug my phone a hissing noise comes from the charging port place... it started all of sudden.. any idea what it could be? i get afraid when it happens as i fear it might explode.... googled it and saw many other threads... some say its normal for fast chargers... while some say its better to replace... what should i do??
Samsung charging bricks have always had high pitched noise. It's the internal transformer that's making the noise. But I recommend you monitor it to ensure it's nothing serious..

It doesn't constantly make the noise.. sometimes if i adjust the charger it goes away and comes back after sometime
This is something an 8th grade physics student would know.
Bottom line, if it ain't burning, it's normal.
Now go watch TV or something and let your phone charge.

Is anyone else experiencing a high pitch whine while docked? It only happens when the Transformer is docked.
I noticed this the other day, and if I put my ear close to the dock it seems as though the high pitched sound is coming from the charging port on the dock. I wonder if maybe this has something to do with my extensive battery loss while having it docked. Is this a widepsread issue that others have also noticed?
mine is silent in or out of the dock. A blessed relief as my laptop always gave off a high pitched whine.

Yeah that's exactly what I'm thinking.
Anyone else having this issue?
My dock is silent.
My dock is silent also.
I have my ear to the TF in the dock and don't hear a thing.
So when you guys have your tablet docked into the keyboard and you put your ear up to the pin connect on the keyboard you aren't hearing a high pitched whine?

I could be an age issue. After about 20 you start losing higher frequency hearing. Store around here that don't want kids hanging around use speakers that broadcast annoying tones in these higher frequencies.
I'm 19 and no whine.
I'm 22 and hear the whine. When I undock the tablet it stops, but as soon as I dock it in the whine comes from the pin connector, almost like power is exiting from the pin connector....not the most technical term and I have no idea what I am talking about, but that would be my guess lol.
Mine whines and the dock battery seems to drain excessively.
This thread will quickly turn into, "How old are you? Haha, you have to deal with the whine for a few more years, suckerr"
If the whine is persistent, swap it. To me, that would be unbearably annoying.

Would try to if I could even get in touch with Asus Support. Weeks and they haven't responded to either of my Technical Support inquiries.
I don't have the dock yet but my TF101 charger makes a whine/buzz sound if you are in a really quiet room.
My dock is emitting the anoying sound. Can hear it pretty clearly
My first Transformer had a prductionfault in top of the panel with some glue all over, no sound and no wifi antenna working.
This one have this ****ty sound and an edge bleed in the down left corners (Picture)
This is really ****ty by ASUS.

mine makes awful high pitch noise as well.
for some reason it started doing that and now the battery gets warm too. I am sensitive to those kind of noises and drives me crazy. i have to call asus for resolution. this sucks, i got it for christmas not even a month old and is defective, by the way the left usp port does not work for some reason. i love my table thought, just with i would wish the keyboard works, anyone else has this problem with a possible resolution.
There shouldn't be any noise at all, considering there's no moving parts whatsoever.
I hate bluetooth with a passion. I am a earbud/headset guy.
I noticed when I first got my Skyrocket that there was always a background hiss, like the sound you get out of speakers when it is not shielded good enough.
Any other owners try this? Use the stock headset or iphone earbuds then simply launch an App enough to get it to play a simple sound... do you here a slight hiss for a few seconds after the sound plays?
Also try calling someone using the headset and listen for background noise. I just got a replacement Skyrocket in and it is making the same noise. If I use the speakerphone or Bluetooth it is fine.
My last phone the I had was an Infuse. It is still in my possession and I retested. The hiss is there but it is so quiet I almost could not hear it.
Please let me know if you notice this, it is driving me crazy!
I posted about this shortly after release. Mine does it VERY noticeably, only in the car, only while charging. All 5 skyrockets have done it.
I have found No fix

I can hear it regardless of what the phone is doing. Charging doesn't seem to make a difference as far as I can tell.
Thanks for the feedback in any case. I really... really like the phone other than that.
Its much worse when charging. Search YouTube for "skyrocket feedback'
Oddly enough I can't get it to do it under other scenarios

If you are within your 30 days buyers remorse or have insurance, get it switched out. I believe its a defective issue. I had that happen on my white SGS2SR and I returned it for a new one in box and it no longer has that issue.

I called ATT up and complained. They sent me another skyrocket that is brand new in the box. It also makes the same noise.
I am more curious to hear if anyone else can hear the noise as I have described it.
Skyrocket Hiss
I'm right there with you. Never noticed it until today because thinking back, I haven't used the headphones yet. I was trying to listen to Pandora and noticed a hiss and crackle. It's gotta be interference because i notice it picks up a little when the screen is on. But It happens whenever there's sound that has or is playing. I notice it during quiet parts of videos or songs and when you unlock the phone it hisses for a second (with the unlock sound) and then shuts down until you go to play anything with audio. I can't handle it. Is this on all skyrockets for certain? Software fix? I'm not paying as much as I did for this to be a problem. I know it sounds picky but it really does bother me during use.
I am not sure myself. I can tell you that I had 3 brand new skyrockets lined up and they all made the exact same noises. I ended up selling the one I did not returnes and got a open box Galaxy Nexus from Expansys. I has it's own issues (like the screen) but the audio jack has no problems.
if you have root try installing voodoo control it helps with audio playback

Man that's a bummer. I'm not sure I can give up LTE now that I've had a taste. I'm going in this weekend to the store and will test every phone they have to see if it's maybe a specific batch problem. I have a couple more weeks of my 30 day comfort zone. This phone is just perfect for me apart from that one flaw. Unfortunately I do try to use it for music so I'm having trouble getting over the fact. How do you like the nexus? I was holding out for that when my captivate fell apart.
The noise while charging is normally not a phone issue and will likely happen with a lot of devices. It's the grounding issue with the CAR chargers and the Headphone Aux in.
I been in Car audio for many many years and have competed in IASCA SQ comps. One of the biggest offenses is 'alternator whine'. Isolating any alternator whine from the sound system was always the factor of proper grounding and wiring. If you run your amp power cable, RCA signal cables and speaker cables to where they crossed the powers cable, you're bound to get the noise.
It all depends on the car, the wiring, the grounding etc etc.
My Galaxy s I has an EXCELLENT audio codec/dac and on it's own is a great player. But in my car as soon as I plug in power and use aux, it's unbearable.
Even though the Skyrocket suffers from poor audio on it's own, the whine while plugged into a car's 12v socket is not Skyrockets fault.
Pull your car into your drive way and use a 120v regular charger and then plug the aux into the car, turn on the car.... you won't hear the whine/noise.
All very good info....but out of our 6 android devices and two iPhones....the skyrockets are the only two that do it.

I realllly like the Nexus. ICS is great for the most part and it is nice to be able to flash roms that are straight from google.
Also the phone feels a bit more solid and a little heavier (GSM version) than the Skyrocket in a good way. I do have the grey screen issues at low light levels that other people complain about but at >40% brightness it is pretty much a non issue.
Mine does it too, but it doesn't particularly bother me. I think it might even be a software issue, as the hiss cuts out a few seconds after a sound plays.

Isn't that the strangest part!? I think I could get over the fuzz when music is playing, just gotta turn the volume up a bit. But the killer for me was when I tried using the headset during a phone call and it was a lot more noticeable then I dunno I'm just still so in love with everything else about the phone that I've been reluctant to take it back.
I have this hope where maybe we all got the same batch and they're all a bit defective. I'm waiting until as close to my 30 day mark as possible to ask for another one and then we'll see. If it's still a problem then I think I'll just make due and hope it is a software problem.
Okay so new solution! Wait for the Samsung Galaxy S II Skyrocket HD and see if IT has an audio hiss lol. I mean seriously how many models are they gonna push out before it's over. I'd be so mad if i got the original GSII.
I was wondering if anyone charges or tethers their phone by the USB port on the dock. And if u have any issues doing so. I tried and I can hear an odd whiny buzz sound from the connection. It would be nice to do as long as I am not going to fry it. So if you have been doing this without problems for awhile plz drop a line about ur experience.
I am tethering my EVO 4G to charge the battery. Haven't noticed any buzzing. Using WiFi Tether for the Internet.

If that's the case I wouldn't worry too much. If it was loud enough to be heard from a distance, or over ambient noise then I would take a closer look at it. Electronics does make all sorts of noises (think of the old flyback transformers in televisions before they became all solid-state), especially if considerable current is going through it. Also flyback transformers are still used but on a smaller scale in switching power supplies. They generally operate in the 15-22kHz range. I bet you're a very young person since most people by time they hit their mid-20's lose the high-end of their hearing due to normal aging (faster if they listen to loud music/attend concerts like I did).
Last night I was using my shield tablet and I heard a noise when I touched the screen...thought it might be the speakers so I turned them down and could still hear it, so I put my ear to back of tablet and can hear buzzing when the screen is touched or when an app is running, and it I play a high graphic game its pretty loud.
Is this normal sound of the K1 processor? Anyone else had this before? Wanna know do I need to return it or not!
Thanks
Same here.

been reading about this and couldn't stop until i found a satisfactory answer, so i kept digging and found this :
" This 'whine' or 'squeal' is the sound of these things ( inductors, coils or chokes ) physically vibrating, and it is a sign that they are poorly insulated. However this does not mean they have a shorter lifespan than a coil that does not whine and you really shouldn't lose sleep over it.
Why do they only whine when the PC is under load? What you're hearing is an effect of the PWM frequency, and as you pull more current through the inductor it induces a greater magnetic field in itself and in turn vibrating more aggressively.
Will it go away? Well, Possibly. My 8800GT squealed like a piglet in a housefire for months, and one day the noise disappeared completely. Either some characteristics of the circuit had changed or the windings in the coil had shifted.
Can you stop it? As most people know, you can stop inductors whining by chucking hot glue at them, putting high voltage putty around them, or soaking them in resin and waiting for them to set. Most (apart from PSU) inductors in PCs are covered anyway, so you can't properly silence them.
"
cheers
Got my Shield Tablet a week ago, really enjoying it so far.
However, I've noticed when I settle in the for evenings I can hear a very faint speaker crackle coming from the lower speaker but can still be heard out of the upper one. Its super faint.
I don't know if its when its connected to its charger, or if its happening all the time but I can only hear it in a silent room. I'll check and report back tonight but if anyone else has experienced this, I'd love to know.
Many thanks
I have heard it as well. My hearing has always been sensitive enough I can hear the old CRT TVs when they are on, and even heard the color wheel of an old projection TV going before it finally quit. This is in the same frequency as those things.
I hear a static sound randomly from the speakers and I have not pinned down the cause as it happens at rest and very active times. I believe some of this might be from the heatsink from previous items I have read about.
The second item is the high pitched whine which I hear connected to my S4 power charger. Again, intermittent there, it does not always make the sound, but it does make it often enough that it is not rare.
I only hear the whine on the charger, but I never hear the whine off the charger.
I sometimes hear both the static/crackle and the whine sometimes, so the whine may be from something in the charging process.
Sorry, I know not much information, but more of a vote that you aren't hearing things and some experiences I have had so far.

I really appreciate your reply thank you, at least I know it's not just me.
I'm just trying to figure out if I should RMA it or not. Sat in bed typing this and the noise is there until the display is off. Doesn't matter if it's on charge or not. Odd though as I haven't heard it all day.
It almost sounds like a very small short in a speaker somewhere.
Thanks again.
It's common to the Shield. I hear it also when it is very quiet.
