So when the unresponsive screen when grounded issue came about, I didn't really notice the problem much myself. However, recently, and I'm not sure when this started, the screen has become horribly unresponsive when charging any time! Doesn't matter if it's on desk, in my hand, stock charger, 3rd party charger, etc., if it's charging at all, the touch screen only accepts half or less of my inputs, making typing impossible. Is this due to the last software update? Anyone else experience this issue? I would exchange the phone, but not if it's not going to help anything.
this happens to me when i use my cheap ebay charger
The fps lifting kernels fix this.
+1 for symtoms seen when using a wonky charger/cable.
+1 due to cheap charger - anyone know why this happens? is the OEM usb cable different spec from the cheap ones?
Hate to beat a dead horse, but the same happens when I plug my phone into the charger I got from eBay. Kind of disappointing, considering that I would otherwise be able to charge two batteries at the same time.
I notice this issue with the stock charger.
I believe the issue was when its not grounded..
Being plugged in is just about the most grounded your phone can get.
That's not the problem.
Starting to do it to me also now.
Just to be clear, this happens to me with the STOCK charger.

I'm having the same issue. i just chocked it up to the new kernel.
one thing i did notice is it seems to be intermittent. Yesterday night, it worked fine. this morning(conveniently when my alarm went off) i could NOT get the dismiss thingy to slide down.
Anyone else experiencing this? I do think it got worse after last software update. Would be nice if the next one improved things.
I emailed support, they did not say anything about it being a known issue, and suggested a factory reset. If that doesn't help, they recommended using my warranty. Would like to hear from more people before going through with the reset.
It happens to me when charging via outlet. Charging via USB connected to computer does not produce the issue.
I think it has to do with grounding.
Same thing happens to me! I noticed it with my aftermarket wall charger.
Bringing this back up, happens to me with a Stock charger.
Is it really the kernel? :\
@Person who said charging is the most grounded, the stock charger is not grounded ( in AU anyway ) and therefore it is the LEAST grounded.
ive noticed this happening over the past month or so. i've got to admit i've only really noticed this when its plugged into a usb cord i got off ebay. relieving to think it might only be an issue with it being a cheap cable and not the phone but i'll verify tonight with the stock cable.
I've been plagued by this problem for weeks and just discovered that it only happens when charging. I use the stock charging cable and wall adapter. I'm very, very happy to know what the problem is. I'm going to start testing this at various locations.
EDIT: I've tried this on both the wall adapter at work and on my work computer's usb. Same problem, though it seems worse when plugged into the wall outlet.
The touchscreen is fine on my sprint brand car charger and on the usb charger on my laptop. However, it starts missing taps when I plug my usb cable into my usb car charger. I'm going to best buy tonight to buy a different charger and see if that helps.

I have these issues as well with the stock charger and cable regardless of which kernel I use.

Is this a genuine samsung charger? I'm using a generic car charger right now and the battery drains faster than it charges while using sat nav.

I bought one of these chargers too (the CAD300U). It charges the phone ok, but if i'm using the sat nav the battery drains faster than it is charged, which makes it pretty useless.
Anyone got a suggestion of a good charger that will charge the phone even when using it as a sat nav?
Whilst i'm on the topic. What have people found is best sat nav app for the UK? I find google maps to not be clear enough. The route marker is the same colour as the motorway.
I use this:
http://www.amazon.com/Kensington-K33497US-PowerBolt-Charger-Compatible/dp/B003PU01M4
The phone i heard only pulls 650mA so this is way more than enough (2.1a and 1a). safe to use as phone will only draw what it needs. if you use a regular charger they only supply 500mA usually. this results in overheating of charger as the phone will attempt to pull 500mA +. It will also drain your battery as your GPS will probably pull 500mA +
This will probably charge your phone during GPS use instead of just keeping it on.
+ it has another slot so if you own more than one USB device its good to go
I bought the official Samsung one, it was 700ma the charger which was great. But the biggest issue was the ground loop interference from the car (and I am not the only one to complain).
Samsung could have done a better job, or provided a 3.5mm cable with the audio filter in it.
Be warned, £35 for the official one may come as a big dissapointment.
That Kensington doesn't have great reviews on the uk amazon site. people saying it doesn't fit the cigarette socket very well - too tight.
I also found this one from Belkin: Belkin Micro USB CLA Adaptor (F8Z445EA)
But can't find any info on its mA output.
edit i take that back. apparently it can supply "despite being able to deliver 1A at 5V USB power". so that should do the job nicely.
also, how do i get the mods to validate my account so i don't have to wait 5 mins every time i want to post something? - i have tried to find out in the general XDA forum, but there doesn't seem to be any mention of it

Works great for me. I have used it with gps and bluetooth on a road with terrible signal coverage without any problems.

If you get ground loop interference when connecting a 3.5 jack, you probably have a grounding fault in your audio system.
It happened to me, I found out that one of my speakers toutched some metal in the door. The grounding circut in your cd player may also be broken, so when you connect the phone it may try to ground itself through your phone. If you have an external amplifier, you can try to ground the rca cables. You can also try to ground the cd player housing.

So, did you try when your battery at 30%, navigating 20 mins and after check the level ? If still more than 30 then everything goes right ...

I dont know what the battery % was when I connected it, but I know that it was at 100% after a 7 hour trip
Ok ,thanks . This charger works!! Thanks again.

For gadgets like this I usually go to Amazon. There are plenty of choices out there. I use Avantek for my S4. Rock solid. Haven't used a S2 myself but I think it will charge your S2 w/o any problem.
This isn't a problem but more of just a general question. So does anyone else experience your phone kinda lagging or having screen sensitivity issues (have to press hard on screen to scroll) while having the phone charge? This is like a 50/50 thing sometimes it does this sometimes not. So post your experiences with this

Yes indeed. In my case, it's caused by my HTC USB cable that came with the phone. When I use the charger from my old LG ENV3, i never get that problem at all. As soon as I switch to the HTC cable, it's nearly un-usable whilst plugged in. It's odd, because the HTC cable works fine for charging and transferring data, so I don't know, but there's something wonky with it.
Hmm interesting

Nope, you're not. It can certainly become rather annoying if you're trying to use your phone while it's charging.
Yea, using swype is IMPOSSIBLE when plugged in.
I never used to have this problem before, so I wonder if this is something that comes with age of the phone. I've run all kinds of roms/kernels and never had this issue until maybe a month ago. But I think I've successfully narrowed it down.
You need a charger that outputs 5v at 1000mA. Any more or less and you'll get the wonky response. I have an 800mA and a 1.5A charger at 5v and I get the laggy response. And I took it a step further and noticed that I get maximum charging speed (regardless of kernel, I've tried stock and custom/SBC kernels) with a 28/24 AWG or 24/24 AWG micro USB cable. If you still rock the stock HTC charger/cable combo you should be golden.

i don't think its from age of the phone because i just got my phone in december (hw 0004) and i am still using the stock htc charger/cable. so idk its a mystery. nice work finding all that out tho its good to know that i am not the only person who experiences this haha.
I only get the problem when I'm plugged into A/C power, but not when I'm plugged into the D/C car charger... I think it has something to do with how the outlet is grounded. Maybe the touchscreen gets confused by getting grounded through the charging port rather than through your body. I'm basically making this up based on hazy memories from an E&M class I took about 8 years ago, but I think it's close. Anybody with any actual knowledge care to correct me?
i am looking for a decent [working, cheap and quick charging] car charger.
I know I'll need at least a 1amp [right?] however i have seen a few that charger at 1amp and 2.1amp
is it going to ruin my battery if i use 2.1amp?
anyone found and goodies out there?
thanks
I second this request, i've got a few generic car chargers from older gear that i've tried with the galaxy nexus. So far they all come up as charging via usb, and so the phone loses power when the navigation/bluetooth/etc/etc is all on. I understand the power requirements, and looked into the data-cable soldering malarkey solution, but my soldering skills in the "fire hazard" class at best so i'd much rather an off the shelf solution.
I'd be very grateful if anyone could point out a car charger that they know/strongly suspect works fine.
Cheers
so the same car charger i've been using for my nexus one for navigation won't work with the GNex?

No, but it won't charge the battery faster either.
More amps is fine. Your phone will only pull what it needs, even if more amps are available.

Also be aware that even though some car chargers state they can supply >1A current, some phones (like my Nexus One and Galaxy Nexus) will not recognize it as a high speed charger.
Smartphones and other devices check to see if the data pins (D+ and D-) are shorted or have a specific resistance before activating high-speed mode since normal USB data specifications say that devices should only pull <500mA from the port.
I have this one: http://www.amazon.com/dp/B002IW79ZC/?tag=68656c7064757-20, which is supposed to supply 1A, but I when I plug my phone in with a normal USB micro cable, it says it's charging through "USB" vs "AC", where "AC" is the high-speed charging.
I've made a hacked cable adapter, though, which has the data pins shorted. When I use this with the car adapter, it charges at full speed. You should check to be sure that your phone is fully utilizing the charger by going into the Settings > Battery menu.
Hi all,
I thought I'd share how I've gotten on. There's a 2.1a charger that maplins sell that I thought might do it, but alas no - still comes up as "Charging(USB)". I know taFFer solved the problem with a little solder, and a lot of forum threads also suggest the same fix, but the last time I picked up a soldering iron actually ended with a trip to A&E (long, embarrassing, story) so I was still keen to find an off the shelf solution.
Anyway, after reading a lot more forums, I found a few different people recommending the same motorola charger. Amazon UK sell it, so I stuck in an order. Details below:
MOTOROLA P513 MICRO USB IN CAR CHARGER, £5.45*
http://www.amazon.co.uk/gp/product/B000S5Q9CA
*above item(s) sold by and shipped from Keep Talking
It arrived today and sure enough simply plugging it into the car results in it appearing as Charging(AC). I've not gone on a long enough drive to know about charging speed when gps/bluetooth/etc is all going, but if anyone else is after a cheap car charger that just works without hacking your own cable I think this is the one.
Cheers
***EDIT***
After criss-crossing the country over the xmas period i can tell you this charger is working fine for me. Even when using all the gps, bluetooth, screen on, etc that i can muster (while still driving straight!) the phone gains power and would often come out the car more charged than when it went in. The charger has one annoyance - they've built in a blue led to the charger which is lit up the whole time the thing is plugged in and thats kind of distracting, i don't really know what they were thinking with that, but otherwise i've no complaints.

For optimal charging, you need 1000mAh output. How much does this charger output?
SO yeah, I've seen where people have had software issues causing this on the Note 8, and S8 models, is it a bug that crept into the S9 as well? The tech at the Sprint store verified the cleanliness and dryness of the port, thinks it's the port, and they won't have parts to fix it for probably a month or so. I REALLY don't want to send it in to be fixed, so I bought a couple wireless chargers.

It it showing constantly or only when a cable is plugged in? If it's with a cable, have you tried other cables? I had my phone give me that message earlier today when plugging in an incompatible hub. The hub wasn't even connected to anything.

All the time. It has a popup with sound when you plug it in. The rest of the time, it's just a notification in the tray.

Yeah, tried rebooting, wiped cache, power down all the way, multiple times. Tried plugging the cable in while booting. It looks to be charging while plugged in and powered down.
So, the message went away, and it would charge with 2 different chargers, normal speed, not fast charge. Would not work with a charger I have here at home. None are Samsung chargers, but all are QC 3.0, which will report as fast charging on the phone. Then today it charged fast in the truck, and the one at home works, but only slow speed.
I'm not going to stress over it as long as the fast wireless charging keeps working. The battery life is more than enough to get me through a day, and I'm ordering stuff to integrate wireless chargers into the vehicles.
Thanks for reading and trying to help!

I probably missed to ask before, but are you sure you are using the original cable, together with the original power charger?
As stressed by @DeadlySin9 the problem may be the cable. Try other cables.

Yeah, I had tried the original cord and charger. whatever it was effected the phone before even plugging it in. The message would be there in the notifications, then plugging the cable in would set off an "alarm" telling me to unplug it and let it dry.
A couple weeks later and it is working just fine, charging with pretty much any cord, and charger. Ugh. I hope it stays that way! LOL At least Sprint DID give me a pretty good discount on a 2 pack of wireless chargers, which is what I use most of the time, now.

Thumbs up!
So, I've had this problem with my new Galaxy s9 as well. Here's the specifics - this only happens IF the phone dies from running out of power. If I let the battery drain on accident, I plug in the device...new cord/charger, original cord/charger, doesn't matter...and it shows the charging symbol for just a second, and then warning there's moisture in the charging port. There's not... If I set the phone on top of a wireless charging pad for a few mins, it charges just fine.
All I have to do is get 3 - 4 % so I can power on the device and get to the home screen. If I can get to the home screen, I can plug the phone in with the cord/charger and no problems.
I just did a warranty replacement because this problem is real annoying. I don't let the phone run out of power often, but sometimes when I'm traveling for work or camping with scouts, it happens. So, before I sent my old phone back for the warranty swap, I let the new phone run out of power and then tried to plug it in. Same error!!
If anyone has this problem follow this trick. "connect the charger half to the charging port." that is it. works fine to me..
