Loss of touch sensitivity when charging - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

I recently discovered the lower portion of my touchscreen isn't as sensitive whenever I am charging the phone with the original charger and cable.
It is so bad that I am unable to complete the sliding motion to unlock my phone since I am using the white bar for widgetlocker.
Just wondering if anyone has had similar experiences and should I be worried?
Thanks!

According to the quick start guide, (yep that small paper nobody reads) that could be caused by unstable current when you are charging. But i am not really sure since i don't have that problem..

I know this may sound weird, but I have heard that some have found using another charger helped similar issues. Maybe try another charger and see if that alleviates the issue.

I can confirm that it's due to the charger or the wall outlet. I have my SGS2, and I've experienced this multiple times. On my iPhone 4 I also had this issue all the time (I think a lot of people complained about the screen sensitivity while charging), and Apples stance was "change outlets" and that fixed my issues, my friend's issue, and my roommates issue on our iPhones back when. Make sure you're using the correct charger as well, with correct voltages.

thanks for all the replies. i've now tried using the various powerpoint outlets in my house and as well as a few iphone plugs but all of it yield the same result, my screen still remains the same.
in fact, this issue seems to have gotten worse after sending the phone in for servicing 2 days ago and samsung service centre claimed they changed the lcd screen and the motherboard.

Have you considered it could be the cable? Have you tried another cable?

I had this problem once on another device. I think it was due to a static buildup. I can't remember how you fix it but hope this helps for info.

Hey man, Did you got the issue ? I would suggest, if your phone is rooted, you must be knowing how to change kernels. Do that. It should definitely solve the issue. This thing is called, deep sleep or ghost touch.

anybody?
yes, I also noticed that. But its not always. This may be caused by the cahrger or the socket itself, if there are other devices plugged in as well. Touchscreens do react very fast on any kind of unnormal powersupply. I have 3 of those original Motorola wall chargers. but i noticed that only on one of those. maybe its the socket where it is plugged in or the charger itself. i will test is later while recharging my phone.
I noticed this for the first time today. Very strange. And annoying.

I change my charge for another but LG. Same problem. My city is 220v is not 110v.
I know if was more of a common issue on older phones..... perhaps this lovely problem is back with the Intel chips.

What firmware version have you ?
I upgraded mine with latest EU firmware here:
http://forum.xda-developers.com/showthread.php?t=1936512
My Razr was not up to date.
Not a big update but I noticed some improvement: No more lag when zooming out/in the home page, NFC notification get an icon near the clock, before it was a " standard app notification".
I never notice the sluggish touchscreen, maybe this issue is solved on this firmware.

The last version. I update in the last week. FW: Brazilian version 87111012012.XT890
I've had this problem on a number of Motorola phones (and others) and believe it's something to do with earthing/grounding. That could be why it varies from one charger to another, or even perhaps how much current is flowing through the charger.
I'm not an electrical expert, so I might be talking nonsense - but I don't think it will be firmware related.

there are problem with charger or is my house? Here is 220 volts.
So finally i got my battery empty after 2,5 Days
Just tested it with my old charger from a Mielstone 2 and the new one.
There is no lag or slowdown with the new one, but with my old charger the phone reacts very bad especially to light touch gestures. So i guess its a problem with the AC charger. I have 230V here in Germany. Or the Touchscreen (digitizer) is just too cheap and can't handle a non perfect Current/Voltage.
I tested with diferent charger and same problem. I pick up a Samsung SII and some problem with my chargr and I use anothers charge with Samsung II same problem too. I have a LG P500 and dont have problem. Whats happens? Samsung SII and Razr I there are delay in touch but LG P500 I dont have this problem USB never problem.

Hardware Defect with USB communication and charging

I reciveved my phone yesterday and after playing with it for a few hours I charged it last night and noticed it became hot to the touch in a few minutes of being plugged in. Like burn your hand hot and there was a bit of a hot plastic smell coming off it. I unplugged it let it rest. Today I have no usb access to it. No adb, no fastboot. Lsusb shows no devices etc.

Xplodwild tweeted out the other day about issue with USB charging similar to this. Does the same happen when AC charging?
Is this problem similar to this guy?
Watch out for overheating!
seems to be a similar issue - it was very hot on the back side just below the camera especially I'm just afraid it got too hot and something was damaged.
This explains why google was pushing their bumpers instead of a full case I can't imagine a case would be good for this things thermal characteristics.
This happened while charging via ac when charging via usb it just seems to hold steady at whatever level the battery was.
Just out of interest, what surface did you leave it on all night?

I left it on a wooden desk for 5 to 10 minutes it didn't take long
It is no longer charging. I can't get it back to stock to rma I'm not happy :crying:
Woah, all other nexus 4 problems aside, this one is quite serious.
Just imagine what would have happened if you'd have left it on a easily flammable surface and wouldn't have noticed the heat. Worst case scenario might have been a fire or something like that.
If this really is a common problem (I've already seen at least two people reporting similar issues), we might see a big recall campaign quite soon.
I guess you don't really want the LiPo battery in your phone burst like this

Maybe Google should start to sell these bags instead of the bumper
Where you using the provided USB-AC adapter?
I know that my friends GS2 and GS3 got really hot when using my playbook wall charger (rated at 5v ~1.8A) :S
Heard of similiar issues with nexus 7, but the one I'm aware of is still charging.
I haven't experienced this issue yet?
I contacted google play they were quite happy to send me a replacement. Aparently they held back stock in case of a need for returns. HOWEVER they tried to charge an authorization hold on my account in the ammount of $350 I DONT HAVE ANY DAMNED MONEY I JUST SPENT IT on their ****! The only other option they said was to return it for a refund and wait a large number of weeks for orders to open up again or send it directly to LG for the same treatment ?!? I'm PISSED. The guy said that this was not the first case he'd heard of like mine didn't even ask any questions except for the serial number - I'd expect that there are going to be quite a few issues like this.

Yeah, sounds like my problem. Was your microUSB port also loose/creaky like mine? I got Google to RMA me a new one. It's a shame, I love this phone and this one has no give on the screen whatsoever and no rattle. The port though and the screen flicker are another story...

I don't have screen flicker yet and the port isn't lose I'm thinking somebody cut some corners on the voltage regulation

Damn, I guess this is sorta good news for all the folks (myself included) whose banks dropped the authorization, haven't had Google recharge us, and have the phone in hand.

Does anyone know if this is normal

I'm using the charger that came with the phone. I also noticed my phone discharges while charging sometimes. Is this normal? I didn't wanna make another thread for another question so here I go, auto brightness has my phone at 100% regardless of lighting, is that normal?
Sent from my HTC One using Tapatalk 2
Both circumstances definitely not normal.
There seem to be serious QA issues with the genuine HTC chargers recently. Both myself and my wife have been through several in the last year. They just don't seem to be as reliable as they used to be and I've given up buying them. If you contact HTC they'll just send you another pup. Try a Samsung/Sony charger. There is nothing special about one charger or another, other than the having the data pins shorted out so the phone knows it's plugged into a wall charger and not a PC, and rated current output. Avoid un-branded cheaper ones as these do not have decent voltage regulation or smoothing, and do not need to meet the same standards for manufacture. These CAN cause damage to your phone. I have used a Sony charger for the last few months on HTC phones without issue. I use my friend's Samsung charger whenever I go over to his house without any issues too. Just make sure the charger you pick can handle the current output that your HTC charger states.
Auto-brightness stuck is also not normal. I take it you have tried manually toggling it, and I factory reset? Are you unlocked/rooted? A bad kernel flash perhaps?
If you've tried all this and it's still stuck, look to see if you have a faulty light sensor. Download an app called Elixir 2. You can check all phone's sensors from there. Select the light sensor, then cover and un-cover the sensor and check you can see the light values changing.

Would I be okay in buying a note 2 charger for my phone I know it pumps out 2amps instead of 1. I'm fully stock and I downloaded elixr 2 and it shows my light sensor works fine. I just have to manually uncheck the auto setting for some weird reason to get it to work.

It should not be getting hot for average use. Gaming maybe, but web browsing and navigating menus definitely not. I seem to remember my One X suffered this in early firmware versions. Later versions fixed it. Which version are you on? Have you had the 1.29 update yet?
I know factory resets are a pain, but it will be the first thing HTC ask you to do before sending it back for replacement, so it's best to to get it out the way if you are already on 1.29. Failing that you can put your faith in the good people here to provide a kernel and base that solves any heating issues. That is what I did, sacrificing my warranty knowing I have phone insurance should the worst happen.

[Q] Anyone else have broken wireless charging? Help me out.

Hey guys.
I bought one of those NewWisdom stickers and it worked like a charm..... for a week. Then it would sit on the charger, show charging for a second, and then it would "disconnect". I am using multiple Tylt's and other chargers that I know work, but this error happened.
I read that the little stickers can be crappy and go bad, so I asked for a warranty replacement. I got a new one, installed it, and bam, same issue right away.
Is it more likely that I got 2 faulty charging stickers? Or that something is wrong on the inside of the phone?
I know you've posted on the threads re: the sticker.
Re: breakdown of the charging, I think the most relevant thread re: this is here:
http://forum.xda-developers.com/g4/help/qi-stopped-t3176818
Though lots of reports here too:
http://forum.xda-developers.com/g4/general/wireless-charging-meltdowns-t3163156
Are you saying that right after the new sticker install, it never worked? Or it worked, then stopped?
It's becoming a widespread issue. Not everyone, but A LOT of folks.
My personal opinion, based on my observations on 2 phones using an OEM charging back, with a new sticker as a backup checker, is it is a hardware issue within the phone. Or perhaps some software issue tied into the hardware.

Thanks for the links. The Additional information helps.
I posted to see what sticker was best and if anyone had one die on them. Seems that this is common enough. I hadn't posted this exact question before.
The new one i bought never worked. I know the pins are lined up and I even padded the back of them a little. My QI pads all show a green light, then a red light. Makes me think the sticker works just fine, but the inside of the phone is FUBARed.
I want to like this phone, i really do.
yeah i use cheap china 5 dollar qi pad with g3 few weeks and wierless charging gone...

Hahah, me too! The camera, if you don't get one with a pink tinge overlay, is fantastic! The iffy touchscreen issues are fixed with the 10N update!
The fact the wireless charging capability keeps breaking down as a hardware issue is ridiculous though.
I may post a poll to see if anyone has managed to keep their charging ability >1 month. Maybe when more time passes, as the phone is still quite new.
Just to let people know... I got a replacement today and the back that didn't work on my current phone works perfectly on the new one. For some reason... This issue is tied to the phone and not the stickers coming out.

Yup there's definitely a faulty part in these phones.
Let us know how long the wireless charging lasts on this one.
Just a note, my wireless charging also stopped. It was a sticker I put on the original back. Just figured i'd screw with it later and that it probably wasn't making good contact so I picked up a regular wireless circle case to use in the meantime and it's also not charging. Likely something in the phone but I have no idea where to start. Oh well, that month of wireless charging was nice again. (and yes, I've tried different chargers that I know work, etc. Hah!)
Going strong for 4 weeks and still charging(with three different QI chargers and two different stickers). Possible cheap quality chargers are blowing out the hardware?

Always a thought, but I use the OEM original Samsung Qi charger, which has done fine with my S4 for years.
For any who have tried wireless charging, I have a poll and questionnaire re: your experience. Would greatly appreciate your input.

Note 5 Fast Charging Doesn't always work

So I've had my Note 5 for a couple weeks now and I've noticed the phone doesn't always fast charge with the included charger. Sometimes the notification only shows "Cable Charging", I would have to unplug and replug the cable in to get the "Fast Charging" notification. It seems like the problem is the cable but it could very well be the software as well, I do not have another cable to test this theory. This shouldn't be happening I paid $900 for a smartphone with a capability that samsung heavily advertised.
I've contacted T-mobile and Samsung about the issue but they aren't admitting its a known issue. Anyone else experience this problem?
Apparently this is fairly widespread as I found a thread on androidcentral forums. (Can't post link due to filter)
I have noticed the same thing.
You SHOULD try with another cable.
I had the same problem until i tried using another cable and it works until now.
Change cable or restart. Restart works for me.

I've restarted the phone before, the thing is the problem resurfaces so as stated above it might be the cable's fault. If that is indeed the case, then Samsung needs to step up and stop shipping faulty cables or acknowledge the issue. They are letting a poor cable design ruin the reputation of otherwise a great phone, god this company can be stupid.
There are more than a handful of threads on this same topic in the Q&A section, you may want to read through them and see if you can find a solution.
