Hi,
I have this strange problem happening since yesterday on my brand new Salsa. When I put it on charging and leave it on a wooden table, the touch screen responds weird to my touch. The ring lock will not open all the way or shortcuts will work weird. The soft keys at the bottom too go absurd not responding or giving different options.
If I pick the handset (probably providing grounding), everything works normal thereafter. I'm using only the original charger provided with handset.
Additionally even the sound into my car's auxillary port is behaving as weird filtering or dimming the vocal frequencies but allowing the music to get through.
Does anyone know why this is happening?
Only incident to have caused this I guess is when the sales guy I went to plugged the phone onto a blackberry charger yesterday for a few seconds.
Could it have caused some damage to some internal part - diode or something that is leaking AC voltage onto the capacitive screen ? Can I have it repaired at HTC ?
Since it's not even a week old, I'm too distressed about the weirdness. PLEASE HELP!
does seem like it could of done some damage as blackberry's do take a lot more juice than the salsa, personally i would take it back and tell them about the problems you have had only since the dude abused the phone lol
I will surely be taking it back but want to confirm if its the problem with the phone or charger, because I do not see this problem when I charge from my laptops USB.
And I want to know what it is before I take it to them. Its much safer to find the problem and tell them rather than allowing them to figure it out themselves and in turn damage something else.
Thanks
your laptop will deal 5v 1a max before the computer will cut off the usb supply due to risk of overload, new blackberry chargers deal a lot more than that due to the juice the device needs to charge, almost like different laptop chargers the difference in the supply would kill your laptop, i don't have any problems with my device regardless of surface it is resting on.
I have the same problem
I have the same problem, but it was observed from the time of purchase. So do not worry and take the phone in hand))
Resolved
With some searching I resolved this problem or I can say I at least know why this is happening.
It is the charger that is faulty and not the handset. I changed it with another HTC charger I had and the problem disappeared. I figured the most logical explanation is what I read in one of the post elsewhere in this forum.
The charger could be faulty to be leaking some AC voltage along with the charging DC juice. This leaked voltage interferes with the sensitive capacitive touch screen. If we hold the handset in hand, we are providing a natural grounding and hence the problem disappears.
I personally would not like this to continue and so I'm going to take it back to my vendor for replacing the charger or if the need be, buy a new one.

Try using another charger and see the difference. Hope you can get your charger repaired or replaced!
Take care.
this is due to a grounding problem or/and leaked ac current....
This problem occurs when your charger supplies more power than required by the phone to charge.The only solution for your prolem is changing your charger.

I had once another problem, that my Salsa overheated (red-green blinking) when I charged it and my Wifi was on. Maybe a background-process could be responsible.

Well I'm at about 2% battery life, and it will not charge. I'm using my computer to charge it. Charging it from the wall hasnt worked for me for a while, not sure why.
Anyway I was wondering what it can be? I doubt my battery's dead or something is wrong with the phone... I'm sorry if this question's been answered, but I couldnt find an answer on google.
If USB charging works, but not charging with the AC adapter then the adapter is either bad, or plugged into a bad power outlet.
Nope it's neither of those because Ive tried two working AC ountlets and two warking cables. However, that's not my problem, my phone died and I can't charge it :-/
Ya so the phone died. It didn't look like it was going to charge on the USB, really weird. Anyone ever have there phone refusing to charge? While it was alive I tried to run activesync; that didn't work. So what should I do?
Btw, I've had the phone for a couple months now and I haven't had any big problems. I don't think it can be my phone failing, worst case just the battery. I've had something similar before but it fixed itself, doesn't look like thats happeneing now.
Battery
Maybe charging from the computer wasn't such a good idea. I recommend changing the battery and the charger and always be a nice boy and charge from the outlet ::- ).
I had the same thing happen to me - the connector at the bottom was broken. I had to do a return to factory. I looked (using a magnifying class) at the bottom of the phone and clearly see a crack in the connector.
It doesn't charge from the outlet.... I kinda just explained that lol

Hmm my connector does look a little bent. However it would of had to be like this before, and it was charging until I let my battery get to 5% :-/
I had a similar problem with my Kaiser a couple of weeks ago - it started to crawl and a soft reset took over 15 minutes to come back up to a working state, after which the battery wouldn't charge. It definitely wasn't the charger at fault as that still works on my TyTN. Phone was about 3 months old, so called Vodafone UK who seemed to think it was software related and so provided next day swap out. Old battery works in the new handset so never did get to find out if it was hardware or software that caused it to die.
Here's what probabally happened... you meant to stick you stylus in the reset hole and accidently put it in the usb hole... thus bending your charging port. I did it and when I plugged it into my car it would actually discharge the battery.. but when I plugged it into an outlet it just wouldn't charge.. if I were you I'd go see if it charges in a car
I appear to have a similar issue when charging from PC usb, and have identified that if I put pressure up or down on the charger it will charge the kaiser. But if plug in the charger without applying directional force it will not charge. Currently i have a small weight resting on the mini USB chargin input.
So obviously something up with the connector. But I haven't jammed anything up the usb port to my knowledge. Are these ports really that flimsy?
Tilt owners: If charge mechanism breaks, is ATT cool?
Oh no, now I can't charge or sync my Tilt.
My power is slowly running out.
What do I do? This is covered by manufacturers warranty in a year, is
ATT going to take my Tilt back and give me a new one?
I need my phone to be working and working well.
Thoughts?

Charging from the computer should be better than the wall, given that the USB ports on the computer have a 5.5v output, while wall chargers have 5v.
Sorry this was previously posted in the wrong forum, mis described as a tytn!
My son is unable to turn his tytn2 on, I think the battery has run down completely, as when I turn it on, I get the "smart mobilty" flash screen with the RGB data, then it turns off as if completely flat, when I plug the charger in, the led charging lighton the top of the phone does not light. At the moment I have tried removing the battery for a while to see of that "resets" it, I have also tried soft reseting but no joy yet.
Doing a bit of research, it looks like the fuse may have blown, I have emailed a repair company who have quoted £40+vat + £6 postage each way, which works out at £58, is the fuse the likely cause, could I get fixed anywhere else, looking on the htc manuals it would appear to definitely not be a diy fix (not for me anyway!)
Try charging from the USB cable plugged into a PC

Sounds very familiar so far... no blown fuse involved here however, it was a blown HTC supplied original mains power supply unit in my case - the light on the power supply stopped working also. Although I could have had this replaced for free under warranty, I didn't want another of the same type (which is all HTC said they'd provide), so I splashed out on an £8.99 Power Supply from a company based in Aylesbury. It has a shiny black plastic case (nicely matching the TyTN II case), works at both 110 and 230 Volts and came with 4 interchangable mains socket adapters for use with different mains sockets around the world. Before you rush out to get another PSU however, check if the light on the power supply still works. Will the phone charge if you connect it to a PC via the USB cable and does the phone light come on in this case (note that the phone doesn't need to be powered on to charge the battery this way, as long as the PC it's connected to is up and running)? If not, you may have a damaged USB port on the TyTN II and although this can be repaired, if it's out of warranty, a repair centre would need to do the work if you're not handy with that sort of thing. HTC have a repair depot in Kingston, Milton Keynes that should be able to do this sort of thing. Depending how your results go with the above tests, you could give them a call, the number is in your manual.
I have tried 2 chargers + the usb, no lights on phone, if I plug in my TP2 it charges correctly, so I think the fault is with the phone, it is now getting as far as the windows screen then dying (presumably after standing for a day or so the battery has recovered enough to go a little further) so the fault would appear to be somewhere in the charging circuit.

Which includes the USB port on the bottom of the phone. Have a careful look for any bent or broken pins there. It's also worth searching here on xda-dev for broken Kaiser USB port threads because this is a topic which has been posted about many times.
If you don't want the expense of getting the phone repaired and can make do without a working USB charging port, you can always buy a Kaiser charging cradle that comes with an additional battery bay to use as a spare charger then just use the battery bay to charge a spare battery and swap them over when reqd. You could also use bluetooth for Activesyncing (buying a bluetooth dongle for the pc to be synched with if needed).
My sons 8925 did the same thing.. and even though his USB looked to be "perfect" it was the problem... It stopped taking a charge from it.. out "work around" involved ordering one of those phone docking stands which had a seperate battery charger and an extra battery or 2.. Then he just had to swap batteries when one died and charge it in the stand.. We did a 3 battery... 1 for in the phone, one for in his wallet so he had one to swap anywhere, and 1 for in the charger.. it worked well (and he is a heavy user of the Wifi and GPS and such)..I hope this helps you out!
Hi guys, I have a samsung galaxy s vibrant from bell, and lately I have not been able to use my phone while charging. My phone lags and does not respond when i try to unlock the phone to go to the main screen.If I want to make phone calls and while charging the phone i would have to dial the number first then plug in my charger. But once its plugged in the touch screen does not respond at all. please hellp!! I;ve tried deleting apps to see if i have downloaded anything that may have caused it but it hasnt worked. I tried soft reseting, taking the battery out. So far nothing has worked. Any one else with the same problem?
Same Problem
I have the same problem with my Samsung Vibrant....I don't see the same problem with my usb to wall-outlet charger....however, the touch screen freezes up when I use a third party charger. Please help.
I have noticed this too. Anyone smart why this happens? Its not just galaxy s phones btw.
Noticed the same problem. While charging, the Touch screen doesn't work. Especially while using Swype, the Line is jagged.
....and automatic PIN
I have exactly the same problem (i9000, Sweden, 2.1 update 1). Unfortunately I did not think of the charger so I kept removing the battery
When connected to the charger when starting the phone and I have many pictures or video files on my memory card, the text "media scanning" and "media scanning finished" (or something like that) keeps repeating in the system info. When the PIN code windows appears, numbers are being highlighted quite randomly. Sometimes the "ok" button is indicated as well, so sometimes I have been forced to use my PUK code because all 3 PIN code tries had been done with noone actually touching the phone
Again, without the charger (and/or many media files) it works.
Maybe froyo could help
I am on 2.2 Froyo and it still happens for me.
Same problem with Froyo JPO!!
Problem with Selective devices or all the devices are having the same issue?
We need more confirmations.
thats because third party chargers have different voltage and charge that will affect your capacitive touchscreen. HTC chargers are recommended, since they are also touch screen based phones.
just searched for this problem and solved it immedieatly thanks to hoopjunkie's comments
i've 2 chargers,
the one came with the phone has output 5.00V 0.7A
one claiming to be samsung has output 4.75V 0.4A
I had never used the phone while in charge so never experienced this issue until 5mins ago
for some reason i was using the "fake" one since.
lesson learned check the voltage values, which i normally do, but trusting too much to the sellers got me.
ow and for the record I'm on froyo 2.2 i9000xxjpc
I am using the Stock charger. Same problem even with the USB Charging.
i wonder if theres a solution to this issue?
i am really getting tired of this problem -- i am using a nokia n97 charger.
i want to be able to download stuff from the market while the device is plugged in.

Hi, I got the same problem: no touchscreen when connected to USB of my laptop. I already noticed my phone acted weird next to my laptop. Once I ejected my cd-player the touchscreen worked again! So the electronics in the cd-player interfered with the touchscreen.
I've got a Rogers Captivate running 2.2 and I am having this same problem... it only seems to happen since the upgrade. This is using the stock charger and USB. Are there any possible solutions to this?
Same happens for my Samsung Galaxy S while charging from the stock wall charger. But the touchscreen works perfectly fine while charging from a PC's USB port using stock microUSB cable.
I think the problem lies with the charging current. The electrical field generated around the charger's wire due to a 500 mA (5 V) charging current supplied by PC's USB port seems to be doing no harm, while the 700 mA (5 V) charging current of the stock wall charger seems to be generating an electrical field high enough to confuse the capacitive sensors of the touchscreen. Perhaps the usage of a shielding core -- just like on the stock microUSB cable -- on the stock wall charger would help in negating the ill effects of the electrical field generated by a 700 mA charging current, but I'm not sure.
Anyway, my current workaround for the problem is obviously to charge from a PC's USB port. When a PC is not around or not switched on, I'm using a 5V, 500mA charger which was bundled with my iTech bluetooth headset. Obviously, both these methods have a shortcoming, that is slow charging compared to that of the stock wall charger. In my experience, this is a problem only when I use my phone for Wi-Fi tethering, in which case the battery capacity percentage continues to drop even when connected to a 500 mA charger. The positive side of 500 mA charging is that it gives a slighly better service life for the battery.
Same problem here, send my SGS to samsung and problema solved new display and display circuit its a know issue with some SGS's
So I just noticed something really bizarre with my Nook. The touchscreen started freaking out with false touches all over the screen. I used the Dolphin gesture interface to see what was going on, and every touch would register random touch points all over the place.
This happened while plugged into the Nook charger. The issue went away immediately after unplugging from the charger. I was afraid it was a heat issue, but this is not the case. I suspect it is the charger, and I am hoping it is not the touchscreen itself.
Has anyone else experienced a similar issue? I will try another charger later today and see if the problem is sill there.
--MrAnt--
I myself experienced something similar where the default browser kept doing odd things I just restarted and it seems to have gone away.
I tried restarting as well and the issue was still there. It only went away when I disconnected the charger.
--MrAnt--
I've had my nook for two weeks now and have noticed the same thing - weird touchscreen behaviour that goes away the instant I unplug the charger (usb).
I have seen this behavior on phones when I attempted to use cheap chargers. I suspect the voltage was not within tolerance and it caused the problem, based on the testing that I did. If you are using the original charger that came with the unit, you should try to obtain a new one.
I get this issue if my screen gets even slightly smudged. I think that once the official App Store comes I'm going back to stock and getting a warranty replacement.
This is a well known issue with many of the units.

I had the same issue with my first unit, I have had it replaced twice, (not because of this, but another issue). My current unit works fine connected to power. However It came with stock 1.0.1 and that may have fixed the issue in software.

The issue is most likey wit the stock charger wall wart. I have noticed that mine makes some VERY loud buzzing when plugged in and no cable plugged in. Prolly cheap caps in there. Poor filtering at best. This electrical noise is likely causing false capacitance spikes in the screen.
Almost tempted to order a spare and tear it down...put some electronics skills to use and build a better mousetrap as it were.
This happens to me as well. I have used family members and girlfriend Nook charger and it still happens. It doesn't affect 1 out of the 4 I bought.
So I figured out what was causing the problem. I was trying to use the charger plugged into a DC-AC inverter. The problem went away as soon as I plugged it into an AC outlet. I guess the Nook charger is sensitive to non-pure sine waves.
deadbot1, I noticed my charger also buzzes rather loudly when plugged in but not charging. I guess the chargers are not the greatest quality, based on the other comments here.
--MrAnt--
Yep, definitely low quality under the case. I've noticed that mine gets flat out HOT if charging from a low battery condition as well.
Once I'm back to work(stupid snow in SD) and have more free cash coming in I am going to order a spare and reverse engineer it with the goal of building a better replacement. I'll be posting my specs and designs as I go. Gotta see whats in there first...but I'm pretty sure that my new one will be based around a TS7805CZlinear regulator and a picaxe uMC if it needs brains.
I've been using third party chargers for a few days since my original email charger broke. However whenever I'm using the phone with a third party one the touchscreen is a bit less sensitive and responsive. However, I as soon as I take it out it behaves as normal. I wonder if this happens to anyone else? And also can it cause long lasting damage to the phone?
I too have the same problem.. its not that quite responsive when its charging.. Im using by the way the latest stock LC2.
I think this is inherent irregardless if your using the stock charger or any 3rd party charger for that matter. This issue is not on the chargers actually but on the 'laggyness' on the Note's screen when your using it (while it's charging).

+1 Also observed this when charging from a friend's HTC charger, also read a thread about this a while ago, although there was no definitive answer from what I read, just people reporting the issue...
Sorry mate, no solution from me, but you can be sure you're not the only one experiencing this issue.
I'd imagine it has something to do with the fact that the charger may not be able to supply the power that the larger Note battery needs...
LE: No, charging with its original charger or my S2 charger, or even my Galaxy Ace's charger does not make it less responsive. HTC charger...does
Used to have same problem with iphone too. Cheap Chinese chargers have same effect.

I think from a simple deduction, when your charging, your actually charging the phone's screen itself. Now this maybe wrong but I've read somewhere that what's mainly holding the power on all touchscreen phone is the actual screen itself.
So if your charging the phone, your actually charging the screen and if your using the phone(naturally using the screen itself) you are in effect disturbing the charge because the power it needs to fill up to recharge the phone is being use also to discharge it (thru constantly using the phone itself.)
This is an issue with many android devices. And some do it even with the OEM charger. I've personally experienced it on 3-4 of my phones.

Sorry, but this is bull****. Phones have batteries like any other portable device, and this is what is charged.
I am speculating entirely but it is most likely that the voltage coming in from the USB cable is ****ing with however the screen detects your finger (i.e, via capacitive sensing). More speculating but I assume that having some sort of electric field near a capacitive screen will cause issues in detection (I've had the same effect happen with the capacitive buttons near a plasma ball; they caused false detections of the button being pushed). Then again, the phone is full of electronics + radio transmitter so I might be wrong.
Basically, buy a better cable, or it might just be a general fault with this sort of thing.
My HD2's screen used to go crazy when I charged it with a Chinese charger, like random screen touches at warp speed. If I used a well made charger, all was well.
The touch screen did eventually die on the HD2, and I had to send it back for repair under warranty. Now, if I get any jittering/non-responsive screen behaviour, I ditch the charger.
I've experienced this too, but it is not necessarily the charger, but the amount of power delivered by the charger.
I used to live in a rural area and the power supply was bad. We only got about 150V through the wall socket instead of the full 240V.
Using my stock charger on my Galaxy S, the screen was laggy, but if I used the same charger on a good power outlet in town, it was fine.
I've also used cheap no name chargers that are laggy even on a "good" wall socket.

speculation and assumptions are just cousins..
Anyway, you are talking about capacitive sensing and stuffs. Capacitives and resistives only apply to touchscreens and none on qwerty phones. Your 'speculation' about electric fields on capacitive screens are actually correct, but I would like to go back to what I said again, the phone draws power from the screen itself. So when you touch the screen (to perform gestures on it), you are actually drawing out power from the phone. your finger performs a conductance to the screen. Your say of 'false detection of the button being pushed' are actually magnetic fields that is try extrapolate from your fingers (as a magnet) to the screen, thereby causing a marginal errors on the screen's predefine calibration.
That is why you may have notice that whenever you have your phone charge, and your actually using for example to type a message on your phone, you can clearly see a margin of seconds in delay when letters will be registered to your message.
Try to simulate that with the phone charge and when it's not. Clearly you will see what I mean.
this is what the word- ferromagnetism is all about.
anyway, I won't delved with that as it's in the realm of physics already.

Had this same problem on my Dell Streak5 when using a non stock charger. The fix at that time was to purchase the small longitudinal magnets that are made to surround and clamp onto the usb cable. I had to place two on the end closest to the Streak. Corrected 80-90% of the problem.
I got the magnets at Radio Shack. It's been nearly two years ago, but I think I paid about $6 for a pack of 2.

What? Only 150V? I don't believe it. How then other things work?
Sent from my GT-N7000 using Tapatalk
Well I was told it was 150V.
It took a lot longer to charge my phone or laptop there than it did at work in town (using the same charger in both locations), so there was definitely a lower current coming through.
Solved irresponsive screen when charging
After eight months trying to find a solution, today I have tried with my iphone 4 charger and my Kindle cable and, for the first time,I am able to write properly, as I weren't plugged. I have to say I don't like this device, it's very slow and the screen goes green almost everyday.
NICE GUY
Well this problem is not because of screen quality. Its all about with the wavelength of current supply and change in frequency . Its create some magnetic field and makes your screen behave weird. When we get proper ellectric supply we don't face such problems. Also cheap chargers don't follow quality levels and they generate uneven frequency thats why flux created by them makes screen behave weird.
This happened to my old HTC Incredible S (Vivo).
It only happened when the 5V charger was lower than 1A.
Quite strange.
But you could check if your charger has at least a 1A output.
Should be on there somewhere.
The stock Samsung chargers are 1A as well I believe.
