Touch screen goes crazy while charging

INFO:
Yesterday the screen was completely unusable, it looked like it was not calibrated (like the old qtek's and htc's) and was not only unresponsive but also very slow, so it did click where and when you didnt want.
CONCLUSION:
after some time I realized and was able to duplicate it when the phone was connected to the wall charger thru the USB cable.
Gotta say im using a really cheap wall charger USB connection because the one from the box is not working. (do have any idea why is this?)
In some threads, it also says it is a common issue in SGS2 but no one says anything about SGN.
Do you have the same issue?

read your user manual. It states this there. Did you watch that xda video when you joined?

I know nothing about this issue, but if I were you I'd stop using that charger immediately. If that's the only time it happens the Nexus might be getting over 5.0v from the charger.

thanks, what video when I joined? back in 07 ?

Had same problem w/ cheap charger. It would be all funky touch screen. This happens to most of my other phones too w/ that same charger (Nexus One, Nexus S, G2X).

+1
Also happened with my sgs, so i bought another charger. An official charger. Not that expensive.

I have the same issue
Hi guys, sorry for the revive, but I'm having the same issue as the OP but with both official usb cable and wall charger that came with the phone. Is there any way to fix it? Or should I get another official charger?

Its a voltage issue between the charger and phone. Its been that way since android began.

Didn't hear anything about any solution rather than buying a new charger, it doesn't cost more than 15 €
At least that's what i did...sorry

Thanks for the response. I feel kind of dissapointed because everything is brand new out of the box. I guess I'll get another charger then...

Do you charge your Gnex with Nexus 7 charger?

I love how my Nexus 7 is able to charge my phone very quickly. Do you use the N7 charger on your Gnex without problems?

your other thread you started asks about your phone smelling like burnt plastic. maybe you should use the charger it came with and see if it still does that

I don't use the N7 charger on my phone regularly. I used it last time I went on a trip because the original was at the house.
Sent from my Galaxy Nexus using xda premium

should be okay. your n7 charger provides more current than the standard gnex charger. the phone's charging circuitry will only draw in as much current as it can take without damaging itself.

ever single electronic device i own i charge with the charge with the charger they came with

I have random chargers laying around everywhere. At work I charge with my old Nokia n86 charger. All good. :thumbup:

Using the HTC charger for a few years that came with my G2

All the time. No probs.

Same here...zero issues. When traveling, I charge my Nexus 7 with the Samsung charger from the GNex...and no issues there either.

I been using my old HTC charger for my galaxy nexus on an off for the last 12 months with no problem, I never heard of anyone damaging their phone using other phone chargers that fit, if you lose your charger an buy a generic charger they work the same way without needing one made by Samsung, I know most phone manuals will tell you to only use charger supplied with phone but they always says that an rather you get a replacement through them.I also use to lend my gnex charger to other people at work who owned HTC phones all the time an they have no problem with it.

The entire idea is to have the micro usb system universally, all manufacturers / os. Only apple messes it up.

I use the charger it came with and also several other generic ones (car, work, second office) and all seem to charge fine with no signs of excessive heat. What about charging time? I just came from the HTC Thunderbolt and would leave it charging over night. I thought I read that is not recommended to do with the Nexus. Does anyone leave theirs charging over night?

I plug my galaxy nexus in every night before I go to bed to charge overnight since I got it last December that way its fully charged an ready to go when I go to work every morning, I have done that with every phone I have owned , I don't see how that's a problem.

GNex ~ N7 charger :good:
N7 ~ GNex charger

MicroUSB plugs are universal so all should work fine. Only time it'd be bad is if the wiring in the outlet you plugged into is done improperly.

It should be fine, as someone else stated earlier, the N7 charger is capable of supplying more current, but in simple terms it's a "suck" rather than a "blow"
The devices will all have regulator circuitry in to prevent damage.
The other way around is tedious (charging the N7 from a GNex charger...zzz)

Losing battery life while connected to charger

I'm losing battery life when using the phone but connected to a charger. The charger im using ive used for my S3 and never had this issue. Any ideas why this could be? TIA

Yup. This is one of those phones that you must use the supplied charger. Its more a tablet charger, not a phone charger

For starters....they give you a charger with your phone for a reason. You can't really complain if you aren't using the charger that came with the device. Second, the Note has a considerably larger battery, larger display, and quad core processor. These all draw more power. The provided Note charger delivers more voltage than the S3 charger. If anything you would want to use your Note charger to charge your S3.

Thank you gentleman, just checked and I think the one I was using was a 1.5. Might have been the one that came with the original Note cuz it looks similiar but is black. Btw...I wasnt complaining, just looking for help.

I had the same trouble with note 1 also, I found on the average any chargers over 2 amp tend to work the best. It took forever to find a car charger that could keep up with streaming music especially with LTE.

Thats wierd. I charged my phone with a one amp iphone charger last night. Worked just fine.
But it didnt like my 800 mah motorola charger.

My ipad/iphone chargers laying around will charge it just fine as long as it isn't in use at the time, they can't keep up if I am on the phone, well at least note 1. I tried a usb port on a power strip last night on this and it charged very very slowly also.
Fwiw my car has a usb port also, and the results are much the same.

It's a Samsung issue that nobody is willing to acknowledge. For some reason they only allow their phones to draw 0.1A over usb instead of the the standard 0.5A. Your note isn't recognizing your charger and is defaulting to usb mode. The idea that your phone would need more than 1A just to keep up with normal usage is ridiculous.

Nexus 7 charger killed my gal nex

Kinda had a feeling to not use it as it's a higher voltage but it would charge my phone so much faster it felt like. Well now the phone will just reboot no matter what rom or stock rom I use. If it does get to boot up the screen starts flickering and you can tell something is wrong. It stays on fine in recovery or bootloader but nothing else. I can flash anything the problem is when it needs to boot up. It's very weird but sprint is sending another after they tried to tell me it's because it's rooted.

Wow good to know, almost used it last night to charge my gnex

Strange. I've used sooo many different chargers everywhere I go and never had a problem. If its micro USB, I use it.

I used the n7 charger one time and I swore I smelled burning plastic or something....never again will I use it on my gnex.
Sent from my Galaxy Nexus using Tapatalk 2

Errrr . . . I actually suspect you've just stuffed yourself up some other stupid way. (or the charger you used isn't actually a Nex7 charger)
The Nex7 charger is not higher voltage. It's 5v, just like the GNex expects. It's a 2.1amp charger, compared to a 1amp one for the GNex, but that's irrelevant, as chargers don't "push" current to a phone - they'll only give it what it asks for, so using a 2amp charger with a device that expects a charger of 5v, 1amp, is not a problem - it'll just give it the 1 amp.

Yes he's ^^^ exactly correct. The voltage is the only concern here.. and it's 5v like every other USB charger should be.

I have charged my gnex into a 24 volt outlet an still didn't get problems lol

im guessing the issue lays someplace else too, not with the charger. i use my nexus 7 charger on my galaxy nexus every day, without burning smells or any other issues. id say ive used it at least 10 weeks in a row if not more.

hmmmm I use my Nexus 7's charger with my GNex all the time... and no issues

The only issue I've had with the N7 charger is the USB cord end is too fat and messed up my old charging port otherwise it was fine for weeks

I use an iPad 10w/5.1v charger to super fast charge my gnex all the time. Never had an issue. Only issue here is my gnex charger isn't as fast as this big beast of an iPad charger. Its your software, bro. Factory restore with gnex toolkit, youll be alright

Even on 24 volt outlet the charger will only allow the correct voltage to pass, same way a surge protector works an yea I charge my gnex in my truck cigarette lighter adapter that gives off 24 volts.

Did that same thing happens, maybe it is not the charger but pretty much it's something hardware no matter what software I load it reboots at random times and screen flickers. I was just using the phone one day and it rebooted and never stopped. Tried everything known to man to get this phone to work.
I also was using the nexus 7 charger for weeks and the only thing different was the usb cable is a blackberry but that should not matter.

I use my iPhone 5 charger

I use a kindle charger (and its long usb cable) to charge my gnex all the time.. and that thing is meant for all eink kindle models including the dx. No issues at all.
Have also used iPad charger, old gravity touch charger, iphone charger, 5v is 5v.. so don't really matter what charger you use .

I can confirm that I have used my n7 charger with an aftermarket cable/n7 cable/gnex cable about 20+ times n i never smelled any burning plastic/metal/rubber/carbon fiber. My gnex still performing exactly as b4, except the sucky 4.2 update, that is. That blows, big big time. I mean, i seriously had the desire to slam the damn thing in the wall so many times. But I digress.
Conclusion-Either I have a special super gnex, or n7 charger doesnt affect the gnex. charging speed=slighly increased though. slightly. like 15mins lesser.

I've used a nexus 7 charger with my gnex 50 times+, no issues.

I've had 3 Android devices and 3 chargers. I don't even know which is for which, but I've never had any problems with charging any device with any of the chargers.

Definitely no issues. I've been using Nexus 7 and Blackberry Playbook 2 ampere chargers without problem

Another GN that won't charge, but with a difference, please fix.

I'm having a problem with my galaxy nexus.
After going over my warranty by a month,I started to suffer from the odd charging bug that seems common in GN especially after the 4.2.2 update.
I started with intermittent charging issues, sometimes it would charge, sometimes it wouldn't.
It then got to the point were it didn't charge.
After googling and searching through the internet I found this to be a common problem.
There seemed to be several fixes, change usb circuit board, bending usb tabs, restarting bootloader, flashing bootloader, new battery etc.
I can safely say I have been through them all.
I can still not charge my phone after; a new usb circuit board, and new battery. I did have a glimmer of hope with a flash of 4.1.2 Google factory image, where it started to start charging but then stopped.
In #*#*info*#*# under battery, it notices a usb or ac feed connected, and my computer registers that it's connected, and can enter fastboot and adb. But never says charging.
The one that concerns me the most, is when the phone was powered off, and I plugged in a charger, I would get a charging partition boot up, showing a battery with lightning bolt on it. I no longer get this.
When I plug it in to my computer,I get a connection tone, but then an item not working properly tone, and under device manager it shows item not working properly, and updating drivers doesn't help.
Usb hot wiring the battery, gets everything working, but it's very dodgy.
Do you have any ideas? Is there a protected partition for charging (that is available on boot)? Could that get corrupted? And can it be reflashed?
Any help is very much appreciated
Thanks

So... I'm not saying issue was similar but it's close. I started having charging issues yadda yadda... plugged in saying charging, sometimes saying nothing. Battery drain was ridiculous. With the phone off, it's show as charging but once turned on after hours it would show half charged. I have three batteries and a bunch of charges all the same issue. I swapped out the USB from a broken GN I had and still the issue persisted. Eventually, I saved my data and swapped out the circuit board for the one on the broken phone and all is well. Every battery I placed in the phone was charged... I get a full charge yadda yadda. I'm not saying it's a similar issue but it's close. You might be able to find a broken GN (screen, no water damage) for cheap on ebay and do what I did... just a suggestion.

Can you charge through the pogo pins? If you can, I'd highly recommend doing the touchstone modification.
I've had issues when I'd enable fast charge on several kernels. If you're using a custom kernel, disable fast charge then connect to power.
