Well its a known issue. My galaxy tab plus also had the same thing and my notes charger as well. But it will self resolve once u put it in another plug. Its transient for me, sometimes
It comes and at other times its gone.

It is SATAN.

When I had the note 2 it made a weird noise when charging. I had 2 different chargers.

That high pitched noise is not normal.

These chargers use a switched-mode power supply that usually runs well above the audible frequency range typically several 100KHz. Some designs cope with a light load such as close to end of charge by cycle skipping and this can bring the frequency down into the audible range. This is not a problem per se but may be audible if the transformer is not totally encapsulated. It's like the hum you may have heard on a 50/60Hz transformer but at much higher frequency.

Twitching screen

I've noticed an annoying bug on my touch screen on my sgs2, and wondered if anyone else has this problem.
Basically, the problem seems to be able to be reproduced by, for example, scrolling the settings menu with your finger, then stopping, but leaving your finger pressed on the screen, as if you were holding it still with your finger. Mine seems to be twitching and moving around slightly, it doesn't stay still.
Not a big deal you may think... But if your an angry birds player or a player of any game or app that requires precision movements then this is an annoying bug.
I'm on ke1. Can anyone else try this for me? Cheers.
Mine had stopped doing it now... But, I have noticed it before, so it seems I have an intermittent problem / fault / bug. Anyway, can everyone post here if they notice this... It happens in every app I've used that involves scrolling.
Nope, mine doesn't do this. And I'm glad about it! Sucks man, trey flashing a different rom.

Are you using a non samsung charger?
This used to be a charger problem, should work flawlessly with the charger thats provided with the phone

Could be a glitch in the motion setting, if you go to settings>motion and test the one where you put you finger on the screen and tilt the phone and the background moves.

My charger definitely makes noise... It's usually not a problem and caused by some internal components

My galaxy nexus charger had this same type of issue. Although it would only emit a noise when the phone wasn't hooked up to it. Kinda reminded me of coil whine on certain video cards.
My charger makes the noise too, usually about 1h of use.. Also the charger from my previous lg phone (Optimus 2x) used to make the same noise too. My wife's s2 charger does not make any sound at all..

So I suppose its the way it is and its not a sign of faulty charger is it?

did anyone request a replacement charger from Google or is everyone just accepting it for what it is?
p.s. i found 3 threads for this issue...
I have this issue to. It's annoying when I wake up in the night and can hear it.
Mine is super annoying. I wouldn't be able to sleep with it charging beside me.

same here, noisy when the Nexus 4 isn't plugged.. when I plug it - the noise stops..
I care less about the noise, but can it be dangerous for the phone?
My Chager also make a noice
My Nexus 4 Charger also make noise
actually it buzz like a bee
But just when the cellphone isn't conect to it while conected to the electicity
when I plug my cellphone to it the noice stops!
May be the Nexus 4 charger is mice powered.

In call Sound crackling/distortion in receiver

I purchased the Samsung Galaxy S4 GT-I9500.
I'm facing a crackling/distortion during calls.
I got my handset replaced twice. My 2nd and 3rd handset after replacement also face the same issue.
I have given my handset again for replacemnt.
Anyone facing the same issue?
There's a crackling/distortion during calls at max volume.
+1
I have noticed that too. Beyond a certain sound, there is cracking sound. Happens on Airtel Network.
Yup!!!!!!!!
Same here. More audible when you hear the ring back tone. its like some thin film vibrating over the speaker.
btw I am on airtel too
Same here, when having a call I can hear a crackling sound, it's minor but somehow annoying. Right now I'm not worried but I'm thinking about how it might become a bigger problem in the future.

Take it from me, it is normal.. my colleague who has the S4 told me that he does not have this problem. I personally checked it and realised that the problem is actually there.. but only some of us notice it.. keep the volume above 3-4th level and you should it be fine..

Fixed on MF3 :good:
Sent from my GT-I9500 using xda app-developers app
I can also confirm that samsung has fixed the problem. I am using MF8.
I don't think this is a software issue, but a hardware one.
I disassembled an S4, I unmounted the earpiece speaker. It comes attached with 2 more sensors.
I made a test call with the back case disassembled so I could press with my finger against the earpiece speaker and the crackling noise dissipated away.
Its like by pressing on it the vibration of the speaker was limited and it sounded pretty normal at max volume.
As a workaround, I inserted a piece of low density foam (found in many packaging boxes) between the earpiece and the front speaker grill and the distortion appeared again, but fainter, after I mounted the back case (speaker assembly) and tightened the screws. Indeed, like others said, its best heard when ring tone is playing when calling someone.
The earpieces is found for $3 on ebay as spare parts, maybe I'll try a new one.
I really hope its not a Samsung design flaw. Check the pics. Thoughts?
I'm pretty upset. I paid a lot of money for this phone, it has a problem and I don't like to send it to service to get it raped by some uncaring hands. I would like to have it changed, I hope its not going to be a difficult process as many things are in my country after you pay the money. How hard was it for you to get it changed?
Has this issue been treated in other threads on the internet?
Little offtopic: the best in call sound experience I had was/is with Blackberry Bold series. They have a clear sound, crisp, no distortion, even with a little bass. Sounds solid. Too bad is that limited.
The problem is with Adapt Sound!, disable it in sound settings [Call Sound] and everything should be fine. Hope this helps:good:

Mobile devices can get up to 110 degress(or more) in certain circumstances. For example, when playing highly graphical/intense games, while GPS navigating/streaming music, streaming/playing movies, or AC charging... or any combination of the aforementioned.

I get that, but that doesn't change what I'm talking about. If you're doing any of the things I've mentioned on the phone, it can get very hot and yes, it will turn itself off to protect itself from overheating. Your car and computer do the same things. Overclocking can also cause the phone to generate more heat than normal.
If you're trying to tell me that you're just talking on the phone, letting it sit idle on your desk, and/or looking at Facebook and you're reaching those temperatures, I A) find that hard to believe B) need to know more information to try and help you find out what's going on.
I get your trying to help me and I realize that but your firdt assumption in 100% correct. Yes. I find it hard to believe to but thats what happened
Sent from my SAMSUNG-SGH-I337 using xda app-developers app
Did you ever try turning off wifi, Bluetooth, GPS separately to see which is causing the heat up. That level of heat sounds like a defect but it still would be isolated to a particular component. Should have checked the battery too.

You got a replacement, correct? Is the new one okay? It could have been a bad module or a bad contact not conducting properly. In any case it does seem like a rare thing. I actually love how this phone doesn't get very hot.

High pitch mains charger squeal cure!!!

Does your mains charger squeal with a high pitch noise that makes you want to bang your head against a wall?
Well suffer no more! Here's the simple solution - make a tiny loop with the charger cable at the phone end and rest your phone on it to keep it in place. Voila! The squeal that makes you want to kill is gone!
Let me know me if this works for you. Peace!
Use blackberry cable.
Faster charging.

OP: What country are you from?
ie Voltage / Frequency
Not a problem with me @ 240v 50 Hz....
I'm an electrician, and this piques my interest.
I'm in UK 220 volt, 50 Hertz. I have this high pitch sound from charger that is not constant. It goes higher at occasions during charging. I didn't try another USB cable though.
Sent from my GT-N7100 using Tapatalk 2
I have tried other cables, it didn't help. Must admit I am curious about fixing the problem though, it drives me insane.
I am a little concerned that its a fault in the PSU though as the power light on the phone changes brightness and it seems to coincide with the noise changing on the PSU.
OK, make small loops of the cable near the phone and rest the phone on the loop just to keep it in place. Try making one or two loops and listen for the change of frequency. Also flipping the mains power switch can help change the frequency.

Well i found the problem is not with the cable but the plug itself must be a fault with the design aspect of the housing of the seperate charging plug not being allinged with uk plug sockets correctlym The pitch to it is very similar to a squeal of electrical connection that doesnt have a consistent voltage running through it due to a loose connection being produced from a loose solidified object such as 1 of the the the bottom connectors (try any other plug like a toaster coffee machine etc they will give the same noise when not connected properly). Cant see it being the plastic adjustable top plug as it bares no real objective to the charge other than an earth connection.
I changed my plug from the samsung provided charger to another usb plug-in charger adaptor whilst still using the offcial usb cable that came with my note 2 and have noticed the noise has disappeared and it charges a bit quicker as a bonus. I cant say iv tested the 2 adaptors parallel to each other YET but when i can be bothered maybe il look into it. (For the picky readers in xda i am in my final year of electronics engineering so i kinda have an idea what im talking about just cos my avatar is dressed as a duck doesnt mean im dull as f##k)

Nice try but your wrong. Only high current electrical appliances is connected to earth these days.
Why is it when I use the same power socket for my tv and my charger and only charger gives out the high pitch noise?
Say your theory is correct. Why is looping the cable solving the problem?
I graduated in electronics and electrical engineering from leeds with years of working experience so I know what I'm talking about too.

Or maybe looping affects impedance changing the frequency just enough? I don't know I'm no scientist!

I've also discovered the charger continues to squeal when you unplug it. I think it'd sending subliminal mind control messages regarding the purchase of your next phablet.

I replaced the cable with a blackberry charger cable. Not only is it fixed, but I have a better charge rate which makes me think the original cable was faulty.
