USB cable who turn yellow on the tips, possibility of burning? - Galaxy S 4 Q&A, Help & Troubleshooting

Hello,
I have my phone S4 since launch and today I have noticed my USB cable (retail) turning to a bit yellow black at the tips of the usb.
I show on the red part where the USB cable is going to be yellow/dark
It is possibly of burning or dirty?
What i should do thanks.

I don't know if it is my monitor my eyes or i simply can't see anything wrong because there isn't ...

I can see it (off colour)
Its dirty
Saftey devices will trip long before this usb cable burns.
No need to worry just clean it.

More photos here for you can see it more clearly. It's on the both tips of the usb charger side and phone side for usb.
I tried to clean also he won't go

I wouldn't worry about it.
It is common for some white cables to turn to a yellow colour

Okay thanks mate but my friend have a s4 her usb isn't yellow like mine
I'm more afraid any day I will see my s4 burned by this and if this happen the warranty will work?

Anyone to know if i can trade the USB/Charger back to the warranty?

this does not look good, that to me looks for sure like the cable is burning.
Have you tried touching cable while charging? Is it getting hot?
Another thing to check is, is the area of discolourasion either really soft or really hard in comparison the the "normal" part of the cable or a new cable?
If so then I'd strongly suggest getting a new cable and never using the cable again, cause if it is faulty, there is a chance of fire.
All Assuming of course it actually is faulty.

When he charging the part of the cable aren't getting so hot. Just the charger himself is hot and the phone. After to charge to 100%, he cut the charge and he isn't hot.
Well I touch while cable when charging. He is not so hot. Just normal.
I'll buy a new charger and new cable for my device so thanks for your advice mate.

Edit: Contacted Samsung / Center repair. Apprently it's just dirty from them.

[Q] Loose Charging Port?

Just bought an A500 and I noticed that I can wiggle the charging plug back and forth a little. Anyone else have this issue, or did I buy a defective tablet?
mine is also loose.
two loose charger plugs
I'm on my second a500 and both have had loose charger ports.
Does it interrupt charging when you wiggle it?

no loss because it is loose

It does not affect charging. It is just a little "wiggley".
I'm not sure I would be concerned, not all plugs are designed to fit tight.

Agreed. A little wiggle isn't necessarily a bad thing. As long as it's not loose to the point of intermittent connectivity or just plain'ol falling out then it's fine.

Charging issue..

Bought a brand new Nexus 7 and it won't charge unless I twist it put pressure on it. Is this a common problem straight outta the box!!?? I already returned it once today because original one I bought had been open.

Same here. Except I'm not forcing it in plug it in it shows not charging but it is. Go Asus. U suck.

No problem here, just to make sure u use the provided USB cable and the provided power adapter
my usb cable is messed up. The small connector - the plastic piece that has the usb symbol on it is loose and it just comes off.. I dont really want to return the device just for that because mines is charging fine but still... it's kind of a nuisance.

My note says that its charging when its not, screen always stays on

Have a look at this please http://youtu.be/rGcQA033E84
My Note is charging when there is no cable plugged in, everytime I switch the screen off it comes back on and stays on. Does anyone know what is wrong?...last night I was charging my phone and took the battery out so it could have damaged my device, I also flashed eybee's JB rom the day before but I don't think its the rom.
Soubds like you have crap in your charging port. Try cleaning it with a pin or something small.
I had same issue and it turned out the micro usb port was really dirty.

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.

How do you go about doing this? Sorry but not clear to me. I have this noise problem as well when 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.

I don't know.. Voodoo? It works for me, and others it seems.

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

I just got used to the sound. Initially I was having trouble sleeping but now it's all fine. With the looping.

For me it sounds like that only when phone us fully charged.

Same here, silent till it hits 99% or 100%, then this quiet squeaky noise starts

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.

Charger not charging correctly

Hello,
My s4 no longer charges correctly. I think the end part of my cable is bent as I have to push the cable up for the phone to charge or turn it around. My cable has been doing this for a couple a days now since I dropped my bag on it. I have tried using other old cobbled and they work except they charge extremely slowly. I have tried bending it back and this works for a while and then just bends back to the not normal position. Please let me know you know how to fix this problem.
Thank you.
