3rd party charger screwing with touch screen?

So I've got a bunch of these cheap ebay USB chargers. I was using them with my HTC Kaiser but now I have my desire - When the phone is on charge using one of these, the touch screen won't work properly. It goes crazy, registering its own "touches" so menus fly about, etc. and if I try touching it, it either doesn't register it, registers the touch about 10 times or in the wrong place!
As soon as I unplug, back to normal!
The HTC charger says output: DC 5v, 1amp
This charger says output: DC 5v+- 0.20v, DC500mA +- 30mA
Does this mean these chargers arent quite powerful enough or something? Could I be damaging my phone by using these? They do charge ok but seem to take longer than the HTC charger.

I had exactly the same problem with the G1 and after a fair amount of time researching that issue, I read, and was told that the voltage on many 3rd party charger are not as well regulated as on HTC charger's or pc's USB ports.
On my G1 the problem stayed even after unplugging the charger.
You'd be much better off with a genuine HTC charger or just using your pc's USB ports.

I have the same problem with my phone .. the problem still remained after unpluging and using my own charger.
Does it go away in some time? is your phone ok now?

Well, on my Dream, the problem wasn't constant, but it was there very often, it seem to occur less when I was swapping with some spare charged batteries.
On my Dream the trick was to turn the screen on and off, and it would work most of the time...
I suggest you try to charge of your computer, the voltage output is regulated properly and I was told several times that the opposite, i.e. cheap chargers, were messing with capacitance screens.
I have been charging my Desire with the HTC charger and my PC and haven't had any issues yet.
Better safe than sorry, I wouldn't have got an upgrade if my Dream didn't have that problem in the first place, and it quickly becomes a massive pain! Especially when you have no keyboard.

Problem didn't go away, so I sent my phone to the waranty service.
Using the original charger and original usb cable everything was ok, the problem appeared when I used an usb extender with my computer. First, windows didn't recognize my device, and then the touchscreen problem appeared.

I had the same problem with charger and usb extender but the problem doesn't stay when I take it out. I Won't be using it again that's for sure...thanks for the heads up

i was having screen freezes and stuff with my HD2 HTC desire rom using a 3rd party charger
my guess is , STAY AWAY

I have a JMB branded car charger ([email protected]) with a mini USB connector, but with a Force branded mini USB to micro USB converter. I have no issues whatsoever.

I use a Samsung Micro USB charger and I notice no problems whatsoever, it's like an older version of the charger that comes with the Galaxy S in Europe.
Straight from the plug as it were, it's great, no issues and charges extra fast

[Q] Charge + USB Connectivity Simultaneously

(Yes I mention android development but this is regarding a 'general' topic)
As an android app developer, it's pretty much mandatory that I have my devices plugged into the computer for ADB. However, with wifi / bluetooth / GPS / screen brightness turned on or cranked up, I also need to have the device plugged into something that provides more than the measly 500mA that the computer's USB port can provide. From what I've been able to gather, the USB standard requires that USB hubs and ports cannot supply more than 500mA to a connected device. However, I suspect that there are manufacturers out there that are aware of the need for simultaneous charging + connectivity and have made special cables specifically for this (What I'm thinking of is a Y usb cable where one end plugs into the device, one plugs into the computer and only uses the data wires, and the other plugs into the charger which feeds and charges the device.) Do any of you know if something like this exists and where I can find one? I've definitely tried to Google for it but the phrases I'm using are long and not producing the right results. I obviously don't know the correct term(s) to search for.
If I knew a bit more about circuitry in general and the USB standard specifically, I could probably solder together a cable like this with a couple diodes to prevent the charger from zapping the motherboard's USB, or perhaps, as mentioned, not connect the power wires at all. I do have 6-8 spare cables laying around but I'd rather not start chopping and black-taping unless I get some confirmation Plus I only have one female end to mangle, so... yeah ;p
My idea for the splice & solder (in case no commercially available alternative exists):
Code:
computer - 2 data -----\
|----------------- device
charger - 2 power -----/

Most chargers and phones have some kind of regulator circuit built-in anyway, at least that's the impression I'm under. Generally if you crack open a charger there are only two cables black and red (+/-) which makes things considerably easier but that's assuming you have a charger that's just for charging and not one that requires you already have a usb cable to plug into it (like some that come with phones now). Standard wiring color schemes applied to all the cables I've cut open and spliced so as long as you go black/black red/red from the charger and leave the other wires untouched you should be ok. You'll know if something's wrong quickly because your phone will get quite a bit hotter than normal and do so faster, and you shouldn't need to add any components as they're already in the charger circuit (diodes to prevent current flow-back, resistors and the transformer to convert to dc, capacitors to smooth the current, etc). Just use common sense when working with this, don't solder until you test, don't splice wires together that don't seem right, use a multimeter to make sure you're getting the proper wires, don't work on anything while it's live unless you're properly insulated and even then not if you can help it, all that jazz.

Yeah, my biggest concern would be that I was told that some USB devices negotiate current requirements with the motherboard, which I'd assume goes over the two data wires, but I remember landline phones have 2 wires but both power and data flow over it, so I wasn't completely confident that the two power wires weren't passing data as well. If I run the 2 data to the computer and the 2 power to the charger, and it turns out that the negotiation requires all 4 wires be connected from the device to the computer, then I've just ruined two good cables.
I just am not so super confident in my logic and theorizing that I'd want to risk frying circuitry If I can nab a commercially available accessory that does this for $30 it's a lot less than having to buy another $700 device and a new $200 motherboard (at the least)

I don't think you really have to worry, but I wouldn't replace the charger wires, I'd connect the wires from the charger to the power lines inside the usb cable that way even when the charger isn't plugged in the phone is still getting some power and it'd basically be hooking them up in parallel when the usb and charger are plugged in. You could always go buy a $20/$30 cheapo phone that connects through microusb-to-usb and test the cable on that through a USB hub. that way if something goes wrong you're only losing a cheapo phone and a usb hub, but honestly things shouldn't fry as long as you get the wiring right and don't try to do something like black to red because then you're feeding power from the charger back into the usb socket which is where things get ugly.

I think i've found something on the interwebs, that will actually save you the wire-splicing and soldering
It is actually just what you described, it uses 2 USB ports in order to provide 1000mA to a device.

I know that some of the smaller usb external drives have a cable that has 2 "type-a" connectorsto allow data connection/enough power for the drive. I have not seen these in micro-usb form, only mini-usb. SO, I do not see why it would not work.

Agreed, USB offers about 2.5v of charge aswell as data connectivity of course, I don't understand why it wouldn't work... I can tell you from experence through that it does take about 40% longer, and will suck the life out of a laptop if you are using it on battery mode.

The reason I was thinking about cutting the power wires from the computer entirely is I don't know what dumping 1-2 amps into the computer's USB port is going to do ;p
Edit: Looks like newegg.com/Product/Product.aspx?Item=N82E16817707145&cm_re=2a_output_usb-_-17-707-145-_-Product should do what I'm interested in, if the details are legitimate. Who knew finding a hub with full details would be so hard? ><

just as papabear already said, there are also external hdd, that use this kind of wire.. so it should be no problem. If the ports arent't capable of delivering that power (but as far as i know they are designed for 500mA each), simply you will not get the the full 1 A.
And i must agree, hardware vendors rarely add detailed power info -.-

[Q] Broken Micro USB Port

Okay so my usb port has been a bit annoying the past week - where i had to vigorously wiggle the cable to get it to charge or to sync (and even when it did decide to connect to the computer, it would chop out eventually)
But now it's no longer charging or being recognized by my comp
It's strange because the headphone adapter was working fine, and so was the usb host, but it just wont charge anymore - I effectively now have a dead TG01
Currently, i'll get the orange light, telling me it's charging, but when i try to power on, nothing happens...
So i'm thinking a new USB port which is where I need some help: I'm not sure on what part to get
But maybe This is the one? Comparing the images with the ones found on the net of the TG01 (Yep - I still haven't got mine open yet)
But yeah, just a heads up on whether you think it would work would be epic, or whether you think i should just try a different battery/charger/throw it away (Although i'm almost certain it's the port, as it was working intermitently before - it's now gone altogether)

are u using only usb to charging or an wall charger?

Wall charger, but i tried USB, and still no luck
It just wont charge at all, regardless of the orange light when plugged in now that it's off (though i wouldn't get it when the phone did still have charge left and was therefore still switched on...)

BUMP: Any ideas you clever people? Just some guidance would be nice...
I'm still without my beloved TG01, I'm having to use a **** old Samsung G600

I do have some problems of my own with my USB cable. I believe the problems are due to the cable, though. The wall charger works fine. The USB cable that I use, has to stay somehow "forced"... imagine having the cell laying face up on a desk. The USB cable gets out and is forced by a small pen that stays right near the cellphone, to have a 30% slope upwards, so pushing a bit the cable onto the upper part of the USB port. I do know that you are telling us a different issue, however, maybe this way you could check whether it's just a broken connection and not a completely dead port.

No, this sounds like the exact issue i had...
It was like this with the Charger and USB - where i had to force it to be recognised or charged, and it would still cut out after a while - and wiggling it or knocking it wouldn't actually affect it, it would be of it's own accordance...
But it was strange because the headphone adapter worked fine...
Nothing happens at all now though

Are you try: Settings- Connections- USB to PC- unmark Enable advanced network functionality

I can't turn the phone on because it wont charge, so it's not that

Battery may be defective. Try with any 5V charger, connect directly to battery pin in 10 min

Hi
It vaguely remembers me of something I read on the forum about different micro usb (explaining my different cables do not connect just the same, some easy, some bit forced); I think there also was a drawing. (but I don't have time to search for the exact thread; it was not the "solving usb port mistery one))
Maybe your earphone adaptator don't have exactly the same as your charger? And if it is not battery trouble, find a charger with the "very right" micro usb plug?

Thank you both so much for your response:
I understand why you say it could be the battery problem with the charger - but it doesn't explain the intermittent connection with my computer when using the USB cable. Which is convincing myslef more and more that it's a port problem
One solution for now would be to buy one of these cheap external battery chargers from eBay, but it would mean i still wouldn't be able to use sync using the USB cable and i'm a bit conscious on whether the charger is safe and wont fry my battery
Which is why i'm leaning towards having a stab at reparing it myself
It'd solve the issue directly and it'd be a safer and more secure solution too... (the external charger would have to be ordered in from Hong Kong eBay)

I'm having what seem to be exactly the same problems. I have used 2 x usb based chargers on it - and neither work (whereas they had been working for the past 6 months). Got a mains charger last week - was working for a while - but as of right now, no longer works.
I'm not sure what else to do. I will try later to use the other adapter I have for connection to usb keyboard. The strange thing is - this will probably work but charging won't!
So....is it the micro usb port that's broken? (strange if it is but still works for data)
OR
could it be the battery?

Very strange charging problem!

Ok, first a little background on this issue...
After having my S3 for about 13-14 months I started having charging issues. The charging port was very "loose" and I had to make sure my charger cable was in just right to get my phone to charge. This was annoying, however was out of warranty and didn't want to pay vzw for an insurance claim. This got worse, and eventually I noticed my phone would only charge with 1 specific usb cable, 1 specific wall charger, and 1 specific car charger.
Well, I finally called Samsung and explained the situation to them and they had me chip my phone to them and they would repair it, free of charge. When they had it, they replaced the charging port, the headphone jack, and the screen. I received the phone back after couple weeks, super excited, and immediately charged it up with the cable I had next to my bed. New charging port felt perfect, nice snug fit, etc... Well, after a few days i hooked it up with the original usb cable that came with the phone, nothing happened. So i started messing around and realized that the only usb cables that will charge my phone are Motorola brand cables! At least the 2 cables I have work, and not a single other cable I've tried works! This includes stock Samsung cable, many cheap 3rd party cables, other friend's S3 cables, none work. Also, I have this cheap car charger that is the type you plug a USB cable into that works, however any other car charger I've tried does not work either.
Also, when i say the cables won't charge my phone, it also won't connect the phone to a PC. They do absolutely nothing.
Does anyone have ANY idea why this is happening?!?! It was an issue before Samsung repaired my phone, they replaced the charging port, but I still have this issue!! I can send it back to Samsung for them to look at it again, however my backup phone, a Razr Maxx, just died also. Seems like the battery went dead and now I can't get it to charge, but that's another issue.
So, any ideas?!

What rom/kernal

It doesn't matter. It does this when it is totally stock and rooted. Right now I'm not rooted or anything because it looks like it may be going back to Samsung again.

I think the smart charging circuit may be messed up

Really? How would that cause the phone to not work with any cable except a certain brand?? I'm just really curious and this is driving me insane!!

I would say you are putting mechanical stress on the charging port. This could be from some misaligned or mis-made cable or somehow pressing or pulling the charge cable when its connected. I've never seen this reported by anyone else, but the mechanical connections are not indestructible. If it were a common symptom with 100 million S3s having been sold, there would be a firestorm of complaints.

I have a similar issue. I'm not sure if it's the device or the ROM (CM nightlies).
Certain cables force the screen to turn back on, which means I get negative charge because the screen burns more than the charger is capable of supplying. Other cables are fine. I'm still looking for the pattern, it's super annoying and causes me to have to turn my phone off completely at times so as not to lose my battery altogether. I'm still trying to solve this, any help would be appreciated.

Further info- it's not the cable, it's the converter at the end. I think it has to do with amperage of the charger- if I use the stock samsung one I'm good, it's putting out 1.0A. If I use others that are fewer amps (like 700 mA) it's unpredictable. I suspect a kernel thing, I might download different kernels to play with it.

Always use chargers that is 1 A - 2A the circuit controls most of the charging regulating amps and voltage

Yes, I agree about using good chargers, but my phone wasn't always this way. It used to charge with anything, but no longer.
I enabled fast charge on Imosyen's lean kernel. That might have made a difference, but I'm not positive yet.

Files can copy but will not charge

My phone can transfer files at normal speeds in bootloader mode. It can even transfer files fine when booting up to kit kat. the issue is even though it does all I mentioned, it won't charge (or charges too slow to matter) via USB connected a PC or USB to any AC adapters. I've tried many working cables and AC adapters, could someone please help or point me in the write direction?
NOTE: It on occasion charges normally.

If it on occasion charges normally but not all the time then perhaps you have some internal damage at the charge port. Now I have no idea how to fix this but one other possibility you could try with the Nexus 5 is to get a wireless charger and see how that works out for you.

trying a wireless charger right now, same old game. slow charging still. I did notice the battery readings with Ampere, i attached a screenshot. the temp is negative -30 celsius on average often show a negative charging status no matter what charger is plugged in and EVEN with a wireless charger.
Does this mean I have a bad battery?

I'm afraid your guess is as good as mine at this point. I've never experienced that type of problem. I have experience of damage to the charge port with an old nook it behaved just like you said which is why I suggested wireless charging since we have it available on the Nexus.

yea, i bought a wireless charger to no avail. something either within the phones board or my old AC adapter had gone wonky, put a new battery in and the same thing began happening after 2 days.
