Oh no. Screen calibration issue.

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.

Screen problems on charge

Long story short: for some weird-ass reason, my phone's screen's touch sensitivity goes out of whack /only/ when plugged in. Thoughts?

Output of charger...
I have this same problem when I use charger that has less than 700ma output. I have an old blackberry charger from my storm that is only 500ma output. Anytime I use it to charge my Epic, the touchscreen will go crazy.

I have this problem and it is worse with certain chargers. I'm glad I'm not the only one.

I could imagine that if the power is noisy it could interfere with a capacitive screen. Hasn't happened to me though

Have not had this problem myself. Try another USB charger? Just about anything that's 500mA will work (albeit not nearly as fast as the 2.0 amp charger that came with your phone).
I suspect your charger.

Good to hear it was a simple solution. You might check with the place you purchased it from to see if they will provide a new cable. I guess we can just be glad you didn't find out about the cable during the middle of an Odin flash...

No kidding. That would hurt a little

I am now having this problem after my phone got wet. No AC or DC chargers will work but the phone will always charge from a computer or even the USB interface of a car.
Even if I can get an AC or DC charger to be recognized, the phone will show as charging but the battery will continue to decline.
It is making no sense to me though I assume getting the phone wet partially fried something.

Yeah the voltage is increased to charge you battery when on AC power, at the kernel level. USB voltage is lower. So i'd say surely fried, and will no doubt stop working sooner or later.
I know that on my s2 I had an issue where it would say its charging and when I woke up in the morning no charge at all. The pin/row of pins or bar if you will would bend down and not make good contact. I used a tooth pick to pry up on it every time it did that.

Thanks. I didn't realize that the charging port was removable on the S4 so I swapped that out and all is fine now. :good:

Ummm... No its not the voltage. It is the ID pin. The voltage stays the same. The only actual difference is the milliamp mAH output of the charger. A normal USB plug has 500mA our charger has 2000. How the phone tells the difference? The 2 data pins inside he charger are shorted together. The voltage always stays the same.

Anyone tried wireless charging ?

Anyone tried wireless charging on DT2 or MXF ? And how was the experience ?

Works, nothing special - overnight charge from 1% to 100%

It works, but many of us have problems with the Qi charger disconnecting charge at 100% and then reconnecting after about 5% has drained. Motorola is looking into it. I may be picky on which Qi charger you use.

Maybe I did not notice this problem - as I put the phone on charge in the evening, until the next morning I take it to work.
I use cheap qi charger from ebay - ~$2.5

Use a ravpower qi charger every night, no issues, phone comes off 100% full, cool to the touch. I know some units I've tried with my Maxx back in the day kept it warm through charging.

Hm, I haven't had this issue yet. I use a cheap generic three coil Qi charger. Is the issue just Qi or PMA chargers too? Because I was looking at buying another but this issue would be a little annoying to me.

Exactly how it should work to prolong battery life. Keeping any battery (especially lithium) full charger for long period of time will significantly decrease its capacity.

Never had a problem with that in the past even with wired chargers. I don't think in recent phones that there is actual current on the battery at all times past 100% whether charging wirelessly or wired. I'm pretty sure it goes into a maintenance mode, but it will still show charging on the display which is the important part. That is important if you use it on your nightstand as an alarm clock with wireless charging. My Sony Z3v had no problems staying in a charge state even after 100% but my Turbo 2 does not which causes it to disconnect. It will reconnect after it loses about 5%. If I don't have it silenced, it will wake me up when it reconnects. It also affects any tasks you have programmed to happen when it is charging.
From my understanding, the first Turbo did not have this problem. I think it cropped up from the inclusion of the powermat charging or maybe something related to the 810 processor. Anyway, just waiting for a definitive answer from Moto.

It doesn't seem to affect everyone which may mean it is more dependent on your charger.

Have any Qi charger brand to propose ?

I'm using a Samsung Qi puck - not the newer round plastic one, but the older more squared soft-touch one. Works great, I don't have the 100% disconnect issue.

I use the tylt qi charger the desk top one so my phone is sitting at a 60 degree angle. It works great no issues and every morning my phone is at 100% and cool to the touch

This all sounds encouraging. I think it would be helpful if people could also add a few common notes:
charger / model
any case they have on the phone (or not) when using a Qi charger
whether the phone must be in a certain orientation (e.g., horizontal vs vertical) to charge
whether the phone is at 100% - and stays there after a charge
whether the phone is cool / warm / hot once charged
A cleaned up list developed from this would be a good resource for the user community

Tylt works great phone gets warm. Itian charger is cheap from Amazon but is very finicky.

Uhm, that's one of the sillier things I've read today.
If it drains to 5% it's not terribly useful as a charge system regardless.
A charge controller chip is supposed to be designed to PREVENT the problem you just described.
Each charge cycle, regardless of it's form shortens the life of the battery, period. If you charge it up and then let it deplete it like that, you're damaging it as much as if you left it charging.
You kind of need to leave the stupid thing plugged in or in some wireless charge hysteresis loop so that the device isn't drained. In light of the charge system being supposed to keep the battery out of the loop until it needs to charge it again (some threshold below 100%) it shouldn't MATTER if it's "plugged in" and the device won't be pulling from the battery.

You're talking like battery expert. Well, maybe you're. Then contact those guys and tell them they're wrong
http://batteryuniversity.com/learn/article/lithium_based_batteries

I picked up 3 Samsung qi chargers at 6 quid each on offer on Amazon (UK). They work very well although they are more a convenience thing rather than a method of charging. I use one at work. One in the bedroom and one next to the Xbox great for the work desk to keep the device topped up and frees you up from plugging and unplugging constantly BUT.... It takes absolutely ages to charge so you dont go expecting to be dumping your cabled chargers. I use the work one most of the time as I'm out and about a lot and its very useful to be able to just grab the phone without unplugging and placing back on the pad when at the desk. The turbo charger gets used at home more coz in more likely to plug in to that and jump in the shower knowing that I'll have a nice reserve of power for the pub so yes they work as advertised and work well great as a trickle charge device when you ain't in a rush. If anyone is interested ping me and I'll spend some time on giving more detailed stats such as charge times from 0% and model number of the devices I use. Away for work at the mo so probably the weekend

Raynic
I bought the Raynic Orchard I. It charges the phone just fine, but I noticed that if the phone wants to wake up because it senses movement, it detaches and reattaches to the charter, which gets very annoying. I moved the phone to an angle where it couldn't see me (but I could see it; sensors were under my monitor stand but the rest of the phone was sticking out) and everything went smoothly after that.

Verizon QI charge stand, Verizon case, have to charge upside down
To charge our new Turbo Droid 2 in a Verizon QI stand with the Verizon case on it, the phone must be upside down. It's OK if out of the case. We have a car QI 'base' which it won't charge in either; probably exact same issue, whatever that is. Any ideas appreciated!

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.

Turn off fast charging in settings, problem solved.

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.

Seems to be a problem with the international models.

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.
