Oh no. Screen calibration issue. - Nexus S General

So my main complaint about the nexus 1 was the crazy digitizer. I am sitting here playing pocket legends and all of a sudden my screen starts going crazy just like on the nexus 1. I ran screen test toolkit and on the trace test i got sharp vertical lines that shot out from where my finger was tracing. I did have the phone plugged in at the time and since unplugging it seems to have gone away but the is reason enough to concern. Anyone else had this issue? May just take my phone back and get a replacement just in case.
Update: as much as I feel like a bonehead for admitting this I found the culprit. Apparently the charger i was using is not playing nice with the nexus s. It is the same charger i use for my nexus 1 an apparently it has a different power output that the nexus s doesn't like very much. Hope my mistake will help others.

I tried charging over USB at a friend's house on his dinosaur iMac, the screen started acting completely screwy as well.

this is really an intresting behavior. i didnt know a scren could do such a thing in different charger.. . live and learn

yea, why does this do this? I wonder can it be fixed with software

Why would you even try to charge it with something else since a wall charger came with it.

Because you can charge an Android phone via USB cable?
That's I think an official feature of Android.
And it MUST WORK WELL!
If not, then it is a bug in the software or hardware
I read a lot about this reports, anyone post into Google official forum?

i think you need to check other phones. as far as i know charging from usb less amp than the wall. so it shouldnt show any weird calibration issues or flicker. double check man

Yes, max amp from USB is 0.5A. Typical output for smartphone chargers is 1A. But this shouldnt be a problem, and also less amp means longer batterylife on the long run cause it doesnt stresses battery as much.

I think it's because the touchscreen on the NS seems to be more sensitive than most phones (I can get it to register input without even touching the screen sometimes) that it gets disrupted by other sources of electrical conductivity... such as the charger. Mine is ok, never really tried with the charger plugged in though. I ran multitouch visible test and I was satisfied with the tracking, it's the same if not better than the Vibrant's, which can handle 5 simultaneous inputs.

touch response when charging

anybody else have any issue with the screen not being responsive when charging? i was charging up the phone today and when it got to full or close to full i noticed that it didnt respond to every touch and it was very slow when it did respond...very weird...and im starting to think that the screen is not glass which actually bothers me

The touchscreen is glass. Period.
Now that that's aside, how would being glass or plastic have any relation at all to the problem you are experiencing?
no relation, just wasnt sure if it was glass or not so i threw it in there lol just noticed i have a small bubble under the glass too ahhh
Could be the charger. Sometimes the diodes go bad and allow ac voltage to leak through. This has made my g1 screen act very strange when connected to a specific charger.
also note the screen is only touch with it sense heat so cold fingers will cause this problem also

Yes I have it happen also at times, not always. With AC Charger and USB charging. I have noticied that if use a task killer before putting to charge I am ok.
Innisdb, are you using the stock t-mo wall charger, or a different one/car charger?

Do you mean charging via usb from a computer? Was the computer pluged in to ac? The thing of it is that all of the rectifiers/transformers are made out of really cheap parts. Diodes can and do leak you might never knoww until you plug in something sensitive enough to notice (capacitive touchscreen). Most high end electronics have capacitors to soak this stuff up, but I'm not sure phones have enough space to add capacitors. In a pc the motherboard has caps on it but power supply doesn't .
Also of note is that the battery can soak this stuff up too but as batt voltage comes closer to charging voltage ( like when nearing full charge) this ability deminishes. Its bad for the life of the batt and phone if this issue is a supply voltage fluctuation problem btw.

Transformer's touchscreen unresponsive while charging.

I searched and can't seem to find any threads on this topic. Odd thing is I don't get any SOD or RR on ICS but can't use my damn tablet if its charging lol. Anyone have any input on this?
just for giggles. switch the orientation of the wall charger plug and try it.
I've seen this when charging on a plane. I assume it has something to do with the voltage being supplied.
Are you using some kind of third party charger? These have been known to cause problems on any sort of technology.
I have seen this on my wifes tf once before, never on mine or my spare...
But with 50% of my micro USB cables it will happen on my infuse... Most frequently while charging in the car. The issue seemed to be a combination of crappy cables and crappy chargers and heat... If my phone was hot it was far more likely to occur than if it was cold. I haven't charged my phone via a plug on months though, I have 4 batteries I rotate, keeping 3 charged at all times

I think it's a voltage thing. Im a long distance courier and i have an ac adapter in my van. When charging through a regular wall socket everything is fine. Yet when plugged into my inverter the screen is not responsive, as soon as i unplug it is fine. I typically use my tablet for netflix while im on the road. So i usually end up pressing play then plug it in. My inverter is rather weak, i was thinking of buying a higher output to see if it corrected things.
This post doesn't really help you, just letting you know you're not alone. If you can't charge while plugged into a wall socket, perhaps your charger is defective and is not sending out the proper current?
Good luck, i hope you find a solution.

Hmm. Most likely its my third party power adapter. It's odd that the transformer won't allow variations in voltage. I've never had an issue with any device in the past 10 years using third party power adapters. Guess I'll have to spring for a 30 dollar asus charger . Thanks for the input guys.

Same thing happened with my SGS.
So, it's not a TF only problem.
Happens on Nook Color too.
Sometimes it's not just unresponsive, it's erratic and causes touch events to register all over the screen for no reason. These happen only when plugged in so I assume there's some voltage issue.

Nexus 4 official wireless charger issues

I just got my charger yesterday and it doesn't seem to charge properly. I put it on and it'll charge maybe 10% then stop. Take it off and put it back on the charger and it won't start charging unless I unplug the cable from the back of the orb and plug it back in. This is very inconvenient and I'm wondering if the orb just sucks or is it just mine? Please give me input if you have the official wireless charging orb.
Also I've only tried on the 2 latest releases of Paranoid android rom with their kernel as well as Faux latest one. Gonna flash something closer to stock and let it run over night and see what happens

Forget it. Just use the standard usb cable to charge. It's a waste of $70. It's a nice accessory to have but what the heck.
Can't do it lol. Love the concept. Am I really the only one having that problem?
Sent from my Nexus 4 using XDA Premium HD app
I dont have this issue, knock on wood. Mine charges to 99%, then slowly to 100% and then stops the LED, I turn the screen on to see the % and its charging again.
I am not sure how the LED's are displayed, does the LED off mean its done charging and is on battery now?
In either case, Once I see its at 100% and the LED is off, i remove it from the orb, it soon drops to 99%, 98% but stabilizes.
Ya I don't have that issue , mine charges to 100 then stops drops down to 98 then starts charging agn to 100... If I was u I would install factory IMG get it 100% stock and see what happens if u get same results , ID send in for warranty , i like the orb but hate how its not recognized as a charging dock, Romanbb ( aokp) is writing code to change this tho
I THINK ! Franco kernel causes a extra wake lock but not sure actually testing now with stock kernel will test Franco agn tomorrow. only issue I'm having but it works either way
Thanks for the input guys. Gonna go to stock and see what happens

I had the same issue until some bright person told me that the wall plug was a different ampage than the wall plug that came with the N4. 1.2 amps as opposed to 1.8. This made the difference to the problem you are having for me. What are you using in the socket?
Unfortunately the problem I am having now with this Orb (and another Qi wireless charger that I purchased as I thought the Orb was faulty) is that the N4 will turn off n the middle of the night. Not good when you are relying on the alarm clock!!!
In using the cable and plug that orb came with. Which are you using? The cable and plug that the phone came with? And that's fixed your issue except for the turning off?

I had the SAME exact thing happen! One day I thought, hey, let's switch the charging puck and see if it helps, sure enough it did, and I haven't had the problem since. So, try another puck, the one included with the Orb could be defective, like mine was.

Same thing happened to me recently. It was working, but now mine will charge about 10% and then stop. The only way to get it working again is to reset the power on it either by unplugging the plug or the usb cable. By charging puck, you mean the black plug that connects to the outlet and the other end of the usb cable?

Note 7 Shipments Halted

http://www.wsj.com/articles/samsung...shipments-for-more-quality-testing-1472647803
Sorry if you can't read it
Those damn cheap microusb to usb-c connectors and cheap large voltage chargers .. sheesh. I've had no trouble with mine but then again I have quality chargers and cables I bought for my 6P. My Note 7 doesn't even get warm when charging .. at least nothing noticeable.

Fast charging? As I understand it - and I could be wrong - the problem isn't fast charging. it's people using unapproved USB-C cables and or chargers.

It's not that it's unapproved. It's that they are using cheap cables and chargers. We went through this crap with the OnePlus3 and Nexus 6P. Cheap chargers and cables can do damage.
Well, from the looks of it. Even Anker who is pretty reliable issued a recall for almost all their usb-c cables.

You're probably right. My Note 7 gets pretty warm when using fast-charge. And batteries don't like heat. So, since I don't really need fast-charge when I charge my phone most of the time, I turned it off. Phone no longer gets warm when charging.
Besides, batteries will last longer without excessive fast-charging.

I use these with my Note 7 and Nexus 6P. Unless I just got lucky and got 6 good cables .. I use them everywhere .. work, car (Android Auto) and home .. then these are good. I highly doubt a USB-C cable that works brilliantly with the Nexus 6P would fry the Note 7. I've had mine for 12 days and when I hook the Note 7 up in my truck for AA it's charging as well and it never gets much warmer than if it were on the wireless Samsung charger.

Maybe something is wrong with yours. My Note 7 has been sitting on the Samsung wireless charger on my desk at 100% for the last hour. Since all this has made me paranoid .. I pick it up every so often and touch it to my face. It's not even lukewarm. I don't think fast charging is the issue with this. The guy in China who reported this which later was picked up on Reddit .. his cable was just some black microusb cable with a while adapter on it and no further info. If the cable was a piece of crap and he was using a cheap wall charger .. Samsung adapter or not I think this was the cause of the boom. I could be wrong but I don't think so. Like said about .. the usb-c cable/charger subject was discussed to death about the OnePlus3 and Nexus 6P (Macbook as well) .. and it's always the same thing. Don't use cheap junk. :good:
just be careful what ur using

If your phone is at 100%, then it's not charging. Therefore, it won't be warm. When the battery gets low, 30-40% and it's on fast-charge, it gets very warm. I don't know about the wireless charger, but it's warm with the cable. Either way, I disabled fast-charge and no more warmth.
Are we far away from FW update limiting charge current? I turned off fast charging due to phone getting hot, which is not healthy for batteries, especially if those are hard to replace and I charge overnight anyway, but on some occasion I could be in rush to charge and fast charging is the solution and I want fast charge as option, but if things go like that, the easiest fix for Samsung would be to eliminate fast charge for now.
All phones should get warm while fast charging. S7 Edge did the same thing, so did the nexus 6p.
I charge mine with fast charging every single time.
i use quick charge no problems here

It could be they are using these cable that's being recall?
http://lifehacker.com/some-anker-usb-c-cables-are-getting-recalled-for-a-hard-1785887067
Some Anker USB C cable sold at Amazon last month could blow you note 7 up.
Guys please check if you have these Anker cable and return it back to manufacture.
http://lifehacker.com/some-anker-usb-c-cables-are-getting-recalled-for-a-hard-1785887067
If that cable delivers 20 volts designed for PC, to the phone designed for 9v max, that would double the amperage and quadruple total power drawn, I can easily see how that could burn the whole phone to crisp.
Going back to fast charge on N7, I'm sure it's well designed and the heat well within specs (it's even mentioned in manual), but the fact remains that higher operating temp of battery, the lower (slightly) life span of the battery. With battery sealed inside and rather difficult to replace I want to prolong it's life to maximum and if I charge overnight, which I do often, don't care if it even takes 6hrs. BTW if the faulty cable is the real culprit, it's a very good news and shipping of N7 should resume soon. It would be shame if such a good phone got bad reputation undeserved.

Actually, it's not. It was reported on quite a few sites that Samsung sourced the battery packs locally for it's variations. So the South Korean company that made the battery packs for the South Korean release is the one that is possibly the cause of all this hoopla. The few handsets out of the millions produced that have had issues with these crap cables and chargers have been in South Korea. None of the EU/NorthAm phones have been reported to have had this happen at all. Maybe unnamed sources that aren't Samsung themselves should be taken with a grain of salt. Maybe we should wait for an official statement from Samsung before running in circles and screaming the sky is falling. It's a thought.
I'm not saying it couldn't be a massive, global recall but based on the 30+ articles I've read .. most of which messaged to me by my iPhone owning friends .. this seems like a bad batch in South Korea. I had a gasket issue on my motorcycle that was part of a recall .. will I stop buying that brand because of it. No. And before you start talking about fire and explosions .. oil spewing out of a gasket onto a tire while doing 70mph ... same thing.

Shocked by fingerprint reader while charging.

Has anyone else been shocked while trying to unlock the phone with fingerprint while the phone is changing.
It's not painful but you can definitely feel it and I don't really think it is good for the phone.

Edit: maybe there's something wrong with your protective earth. Some wrong potential? Check your current charger/cable on another power socket/place. Any other charger tested?
Throw away the charger. Not kidding.
PS: There is no "protective earthing" in those chargers, they should be all double insulated (Class II).
I have never noticed it. Are you using the turbocharger?
BS LoL!
in my case when i connect to external music system then fps always gives a shock. also without connecting to charger.
i think its a issue with my music system.

I wasn't using the turbo charger, it was one I had from my old phone, the cable was something I got separate too. It doesn't always seem to happen, mostly after I walk around the office a bit. The static might be from me but I really don't think I should be experiencing a shock as hard as I do from the phone. It might be the cable though because I don't have this issue at home, then again I don't have carpet at home either.
If is static then it still discharges through the charger to the ground and it might damage the phone.
