Warning! When connected to power source

I was a little bit shocked.
My Kaiser was connected to a USB power source from my desktop.
Then somebody called ... I answered, put the phone in my ear ...
and I got electrocuted !
Not hard, but intense ... and I felt quite hot in my ear.
Did you experience the same?
Do you know how to fix?

Most likely a static electricity. Don't wear synthetic clothes.

That's what you get for using a Kaiser without buying me one! j/k

I tend to agree about the static theory. The voltage and current output of a USB port is very low and you'd probably feel nothing even if you were wired directly to it!
The phone also has no exposed metal and again unless it was half drowned in water there would be no connection to you.
There is one small note of caution, something you might want to check if you are concerned. Check the mains plug of your computer and ensure the live and neutral wires are not reversed. If they are your Desktop PC will work fine, but it can lead to the casing and possibly the USB earth registering a charge. I had a TV that gave me shocks on a regular basis for years. When I changed plugs to a fancy colored one I noticed the Live/Neutral reversal. It never shocked me again after it was corrected.

Thanks for all your input, I will check that.
I still have it connected now.
When I touch and grab the area near the "orange" light, I feel a little bit vibration ...
I tested again, no electrocute btw ... but that vibrate feeling, still there.

The vibration is very odd - does it only do that when on USB?
Does it do it on mains charger?
Does it do it when not plugged in at all?
Mike

Your PC is probably not well earthed and you feel some bleeding current. The ear is much more sensitive to this than you fingers so that might explain why you only feel it this way. I would check the PC earthing as this might lead to some dangerous situations if not well earthed OR isolated from mains.

Good point. The vibration may be a 50Hz mains "hum" that you certainly should not be noticing.

I'm not sure about the phone, but the vibrating feeling can be a sign of 'wild-electricity' (i.e. something that isn't designed to be there). I have the same problem with my 3.5" portable hdd, and my wife's IBM X32 notebook. If you were to glide your finger over it's surface, you will feel as though as the surface is.. rough, much like a vibrating sensation (i.e., rough surface gives you a peak-groove-peak-groove feeling, which a vibrating surface gives you, i.e. up-down-up-down). You won't feel a thing if you were to touch it with your usual skin (i.e. finger tips), but try using your sensitive area (let your imagination runs wild here). Anyway, I would suggest you to try using the skin on the un-exposed side of your forearm, near the wrist. That would give you a bit of shock.
Anyway, as mikechannon said, USB do not give enough power to shock you, considering that it is only 5V and 500mA max, that would be like 2.5W. However, as the thing you are touching is on the surface, I'm suspecting that your 'ground' is at fault, that is your PC. To test this, try touching the USB cable, plugged into the PC (without the phone) and touching the outer-side of the cable socket (i.e. the part of the socket that actually goes into the phone), with your sensitive skin

You need to add the following to your registry:
UserElectrocute=NO

Lol ...
Btw, I think that is correct ... the power in my desktop pc is not properly grounded.

How dangerous!!!
Could have killed you know.

I remember when I had the Universal the metal plate on the outside of the lid would behave exactly the same way. When plugged in and trying to glide your finger tip over the plate would give you a vibratory feeling.
At that time this was much discussed in the Universal threads but as far as I remember everyone concluded that it was not a concern / dangerous

HTC Sense Earphone Electric-shock ??

I've got a problem with my HTC earphones (or myself) and I'm just wondering if anybody else had the same issue or if anybody can guide me on what to do.
Basically, after listening to the earphones I would get what I believe is a mild electric shock in my ear every now and then and obviously I don't keep it in my ear after that as it could potentially be fatal (?) and it isn't a nice feeling ! I rang up my contract peoples and they sent me a new set of the handsfree earphones which I received earlier today but after about 5minutes of listening to them I experienced the same 'shock' feeling !! I also tried the first earphones in my iPod whilst at the gym and I got the 'shock' then too and the iPod wasn't even turned on. Hopefully this has happened to somebody else (not hopefully in a bad way) as reading this back makes me sound a little crazy lol !
Thanks for any advice too,
- Ash

Haha
You're most likely wearing some jumper or other clothes that cause a static electricity buildup when the phone cord rubs it. I remember having that with a particular jumper some time ago
Solution, try changing clothes and no, nothing dangerous about it, just annoying.

yeah sounds like static to me

Stop worrying Ash
As already said it's probably static electricity from your jumper/coat/shirt jumping from the metal parts of the earphone to your ear. (unless you got one of those ear/nose trimmer things that has left you with spiky little hairs in your ears )
Technically there is almost totally zero chance of there being a high voltage fault in your HD2 and you already proved that it isn't the phone as you get the same shock from the 'phones in your iPod.
Carry on using the phone and headphones but stop buying nylon jumpers and shirts at Primark, get some nice cotton ones instead
HTH

i get a electric shock if i use the headphones in my laptop dunno why

Nothing to do with mobiles, but I get static electricity shocks from my metal cased 'in-ear' phones on the treadmills in the gym.
The treadmill "belt" being a good insulator; Similar in principal to a Van de Graff generator.
Keeps me on my toes....

You need to ground yourself.

And avoid dry atmosphere.

is your phone connected to ur pc/laptop via usb? i sometimes get a shock when i touch my phone whilst its connected.

You know I have been having the same thing with my iPod just lately, using a pair of Sennheiser CX 300 II headphones. And it's only ever in my right ear, very strange.

Hello Everyone,
That's not a shock.This is a shock

Shock therapy?
I have this problem with my HD2 too!
When i use my phone on battery the shock is very small, just a little bit annoying, sometimes i don't even notest it. But when i connect my phone to a computer using the USB connector, the shock is really intense sometimes. Just 5 minutes ago i got a shock that even made me a little bit dizzy. Changing earplugs doesn't solve the situation.
I'm not using my earphones anymore when my computer is connected to the phone, witch is not acceptable! Too bad the phone is such a good phone, so going back to the shop is not a option. I hope HTC will have a fix for this, but i think that it will stay with me hoping for a solution.

The phone has nothing to do in that, only dry air and static electricity, you'd have the same with another phone or mp3 player
When you connect the device to USB, you connect it directly to ground through the PC, and just give an even better path for the static electricity you're holding to escape
These days where it's so cold outside here and thus the air inside is so dry, every time I walk through my flat I get loaded and will get a serious shock whenever I come too close to something that's grounded. The other day I managed to make my desktop PC crash and reset on its own by going to fetch my headphones and plugging them in without thinking to discharge myself by touching the case first...

My assumption is, that guy was on a suicide mission. The minute he touched those high voltage lines, he was crispy inside and out. Not the mention he dehydrated so quickly from the voltage,he caught on fire like a piece of petrified wood.

I have a bigger problem
Today at work I got an electric shock thru earphones and the touchscreen sensors died within....screen works but no response.
Wonder if warranty will cover repairs/replacement?
Still nice to get some oldschool lobotomy-shock treatments, wakes me up at work

No music at work and no HD 2....devastated.
And now I read a thread about plastic replacement screens for HD 2

Thanks for the waring... will stick with bluetooth
Electric shock? Phew... I never tried the earphone pieces and from the looks of it I don't want to either... So if I read this right the shock can disable touch function from the screen? Perhaps it is better if you all try out a bluetooth headset instead?

It doesn't matter now that the screen is damaged.
HD 2 is made of metal, don't think it matters if I have a wire or not.
But I'll give it a try when I get it back from the repairs.
Funny thou, I had to go back to my Blackstone and no electric shocks, made of plastic
Any tip of some good BT headset/earphones?

Seriously this phone is pushing my patience...

my phone has been giving me problems for the last few months now non stop. first that red light crap on the power button...now this....
My phones screen gets all distorted in Landscape mode. if i flip open my keyboard, it gets all scrappy, then i have to pop out the battery and restart in portrait...it runs fne until i flip the keyboayd out. freezes up and all that crap starts...why is this happening? how do i fix this? ive had the phone for 7-8 months not sure...but WTF man its still not even 1 year old....talk to me somoene is this just a piece of junk i bought? is there a fix? anyone else have this problem? ARRRGGGHHH!!!!!

what ROM are you using?
you should make a backup and then try a hardreset

If hard reset or new ROM flash will not fix your problem, then it is the flex cable that is at fault. I recommend replacement and had it done for my customers. Cheaper, albeit a temporary solution is to attach a thin sticky tape cut to shape to the flex. If you have no idea what I am talking about, then it is the job better left to professionals.

as enigma1nz stated, its the flex cable... i too had this problem, but i didnt buy a new one...
what happen is the sliding wears off the black coating on the wires and expose them to the interior parts, its like rubbing the two jumper cables together, it will spark...
what i did was cover the silver part with sticky tape, that solved the trick

I have owned my X1 for a year now, and yes it is now a piece of junk compared to other phones currently out.
Get a Dell Streak and be satisfied already!

It is not a problem affecting Xperia only, but rather something we call 'All slides disease', it affects all slide form factor phones due to vulnerability of the flex cable. It happens due to sheer act of someone using the phone as intended - sliding it up and down, answering calls in some phones, accessing the keypad etc. It does not mean Xperia is crap, just the downside of a particular form factor. Next one on the list of form factors requiring repairs are flips (clamshells). With a bar form factor very little can go wrong, apart from actual physical or water damage. With the advent of large-screened touch phones, as you can imagine, it's the screens that sustain the damage. Iphones are vulnerable in particular.

Disable screen wake up when charger is connected on tw rom

Is there a way to Disable Screen Wake up on Charger is Connected on a TW ROM?
I know its possible on some Cm based Rom..
My problem is my usb charging port had a short circuit and shows charging even if its not connected to a charger..
It wakes up the phone and says its connected then it shows not connected.... connected again(screen turns on) and phone heats up all day long.
Samsung service centee is very far from my place so im just finding some workwaround for it..
And I dont want to dismantle my phone myself because I might get it worse...
Help please brothers..

I don't know how mechanically inclined you are, but mine did the same thing a few months ago. I ordered a new usb/charge
board off ebay for less than 20 bucks & did it myself. Granted, I've been a repair tech for over 35 years, but there were several
youtube videos that show you screw by screw how to change it. The replacement board also came with a screw driver (torx)
& a plastic pry tool to get the bezel off the device. Took longer to watch the video than it did to replace it.
If you have any mechanical aptitude, give it a go. Being in my mid 50's, with the bifocals, the screws are pretty small, but
I took the torx driver and rubbed it against a magnet to make sure I wouldn't drop any of the screws

Shock while charging ?

Guys it has been almost 5 weeks that ive purchased the device and ive been getting slight electric shock from the metal frame when i use it with the shock case when i charge !!! Also the touch and finger print sensor seems to be a bit messed up while charging ..is it any thing serious? And is every body facing this issue?
And its not earthing issue I've tried it with different wall sockets extension chords and everything

What you describe does not make sense. The stock cover covers up the sides pretty well, so how can you touch metal while with cover on?
Also the fingerprint sensor is built into the screen, so are you saying there is shock when you touch the screen? Also very unlikely as glass screen prevents that amount of electricity being passed thru, it wouldn't be enough to shock you.
Better be safe than sorry, you might want to take a video and return the phone.

ive seen a video on youtube from an indian user who was also getting shocks from the phone and eventually it would not switch on anymore so he had to get another one through the warrant. I am looking for the video but i didnt find it yet.

Lol sounds interesting. Would like to see the video.

I dint mean the sides when its on charge just slightly touch the upper metal portion of the frame!!!most probbaly with out the cover the shock is not noticed cuz a large part of frame is in contact and thus the electricity passes throug!! And i dint mention shock coming out of fingerprint!!! I told the finger print scanner struggles a bit while charging ...not sure if its cuz of any internal shock

I have just bought it from flipkart and i also feel the shock while charging the phone with the included case.
I also tried removing the case and shock was gone so really confused about the situation as everything is shout due to corona outbreak so I can't take it to service center.
So please give me update if it will hard the device or explode the device if I continue to use it

Chargers supply DC current through the USB cable. 'Earth' makes no sense in a DC circuit, therefore it cannot be an earthing problem.
Also, virtually all USB chargers have a plastic case and so will invariably have no earth connection. Even if the plug for the charger has an earth pin, the chances are that it is not connected to anything.

I using k20.. during charging I feel vibration(current flow)in metal plat..why?? No earthing problem or charger problem

The battery in the phone supplies DC current and requires a DC current to charge. The charging brick delivers DC current to charge the battery.
If there is an AC current going to the phone when charging, you'll instantly kill the phone.
Any electric shock perceived when charging is not a result of a residual AC current on the phone case.
It is NOT an earthing problem.
