Quit using a cheap charger.
If you are using the included charger, try running it off of a powerstrip, or with a different USB cable.
I'm not sure why, but this phone seems more sensitive to bad/unsteady electricity than others I've used in the past.

For some reason I took that to mean that his phone wasn't getting charged when plugged in.
You may have a bad phone, OP.

Good point... Perhaps it is I who is misinterpreting. It was my assumption that OP mentioned that to eliminate the most common cause of funky touch response, which you mentioned.

Then I'd agree with Matrix. Stock firmware and not plugged in pretty much leaves hardware as your issue...

I've personally had touch misreads on this phone when using cheap chargers, so that's why I assumed what I did.
I also had this happen to my old Inspire when using a cheap DealExtreme charger, but only then.
Basically, the touches misreading seems to indicate that the current being supplied to the digitizer is inconsistent. Obviously, there are multiple things that could cause this.
chrisphoenix7, have you been using the supplied charger?

Have you pulled the battery?

I have tried restarting the phone several times. The problem is basically when I switch to another ROM. I'm back to stock ROM now and everything works ok. But still sometimes on stock I click on top and it wants to click on bottom.
Really weird.

Is it plugged into the wall charger?
With some outlets, the wall charger can wack out the touchscreen.
Which ROM - we only have Cognition beta, CM7, and stock deodexed. If you flashed something from the I9100, who knows what it'll do.
It actually seems like the non oem charger+ usb debugging causes the wacky touchscreen...not the outlet..

I had it with an OEM charger combined with a Sears inverter.
I think it's anything that provides a noisy power supply interferes with the touchscreen controller.

In case of emergency charge a dead battery.

If this hasn't happened to you yet., and it's going to happen to you later. You have been messing with your phone without looking at your battery levels and mid rom flash you are out of juice, your phone won't charge. The charger appears to be working but the phone just won't charge.
I used to have a droid x and you have to use a special tool by Motorola to change the os on it. It requires you to be plugged in but sometimes won't charge your phone. Mid update my phone ran out of juice, I had a spare battery but the phone wouldn't turn on or charge. After many desperate appempts I found a fairly easy solution.
The trick is you find any usb cable you don't want.. You strip the end with the adapted part of the usb.. You cut the green and yellow wires.. You put the black wire on the negative terminals and the red wire on the positive terminals
This should give your battery enough energy to start itself up if you hold the wire on the terminals for a minute.. Although I'm not sure if this damages the battery.. I would only use this in case of an emergency,

Or use Amon Ra recovery... it will actually charge a fully dead battery.

This is for a situation where you need it charged at that moment.. Not wait 1 week for a charger.. Most people know about the chargers, but shipping is nothing near instant

yep, have 8 extended batteries right now. Don't think I'm running out of juice!
What if you could wire the batteries together is some way to make a 1 week shoe box sized battery. That would be worth buying... If you wanted to carry it around
Sent from my ADR6425LVW using xda premium
They already make these "brick" charging devices. Not a shoe box, just a large battery that can charge your phone multiple times before it needs to be recharged. Pretty sure I have seen a 8000mah and higher.

If I didn't have an extended battery then i would have two stock ones. Keep one charged and the other in the phone.

My phone thinks it's charging

Dear XDA'ers,
My Samsung Galaxy S II thinks it's charging when it's not. Most of the time it does this for 2 seconds and then it repeats. But sometimes it thinks it's always charging.
How can I solve this problem?
Thanks people!

Something is wrong with the charging port. It's a known issue after a while. How long have you had had the phone for?

Is it in warranty?
Sent from my GT-I9100 using xda premium
Mine did the same recently. I think its because of moisture/damage to the USB socket. Took it apart and left to dry in a rice jar, which made it do it less often, and stop when I put in and then pulled out the charger. Next I used a clean,dry toothbrush to clean out the socket. This was 3 days ago, hasn't happened since. (Touch wood).
also heard it can happen when the flat connector inside gets bent slightly,from putting in charger upside down (easily done) or some other way. May be worth having a look and checking if that's an issue. Hope that's helpful,had me worried for an hour or two

Nothing you can do except insurance claim or warranty or buy a new one. Sorry mate. This issue is exactly why I bought an s3, because after a while it gets worse and worse and then it kills your battery life.
Sent from my GT-I9300 using xda app-developers app
It usually is one of the two things: either the USB port is dirty, and you just need to clean with, say, a toothbrush, OR a circuitry issue in which case you need to replace the circuit.

Are you under warranty ??

In a nut shell ...yes
Charging issues are difficult to diagnose, as you are working with multiple components to begin with.
But if different cables and chargers are tested, and fail to improve the conditions, then you are left with the device as the cause.
Additionally, if the device is unmodified, either by software or hardware that generally affects it's function, then hardware is the remainder.
Charging port is the probable cause ...IMHO ....g

Its not to difficult to change it out I bought mine from cellphonerepairshop.com got the OEM flex cable took about 20 minutes to open it up and change it theres tutorial videos on youtube if you are off contract I would suggest that.
Before you switch out any hardware, get a can of air, alcohol, and cotton swab.
Give the port a good cleaning.

Great tip here ^^^^^^^^.....
Thanks ranger ....g
If you dont want to replace the port you can get another battery and a wall charger, works like a charm
I agree. I like my 2700ma batteries and charger. For long days I bring the extra battery. The rig was super cheap too, but good quality.
I've had charging troubles as well
About a month after I first received my note I went to charge it (wall outlet, original adapter/cable, as well as stock ROM no root) and it refused
to charge. Restarting twice solved the problem, but still, every so often, my note will refuse to charge and I am unsure why. When it refuses to charge, it wont accept any charging cable (I check to make sure each is clean) although the phone works normally. Is this a known issue on some devices?
Sounds like a battery problem.
after some more searching around, it seems it was the battery causing my troubles, thanks for the tip! ordered a new one, it'll be good to have a backup battery

You were given several suggestions ranging from cleaning the port to replacing the port - did any of them work?
I'm glad one person got his solution with battery replacement. But thats not stealing. Stealing would be several members turning the thread into a discussion about multiwindows or bricking by flashing an N7000 kernel.

We just switched to Verizon from TMO, got two DNAs and two Nokia chargers and couldn't be happier they charge the phones really fast. Was actually surprised how fast they charge the phones, thought they were more of a overnight charger, I was wrong.

I have the Nokia one and it works like a dream. I never use the usb charger anymore.
I actually have both the LG charging pad from Verizon and a Nokia charging pad (Not the fatboy, but the pad alone) and from what I can tell the Nokia pad is far superior. The entire pad is a charger (It is smaller than the phone) so there is no guess work getting it to charge, it also doesn't make that awful *BEEEEEP* every time you try to place the phone on the pad, it only has a single notification light to indicate charging which i prefer, most importantly it seems to charge much faster than the LG charging pad. The LG pad overtime seems to have gotten more choosy about where i place the phone, and does not charge the phone nearly as quickly as it originally did. (Which was never as fast as the Nokia pad mind you.)
Though in regards to the 2% thing that has not ever happened to me. Mine charges almost as well as a regular charger (at least on the nokia pad), I would also guess your friends charger is bad, or your phone is doing something that is using more power than is being put back into it, or there is something wrong with the phone itself. I'd give it another go and see if it was just a fluke. Too bad you don't have another pad to test with to narrow down the issue you're having.
Good Luck though in any case!
Mine is the qzens.
Just had read that people had their DNA stop wirelessly changing when they had the Nokia one. Probably coincidence cause that's what Verizon sells. I got mine used from someone that sold their DNA
