I bought a generic Qi wireless charging kit. It has a white receiver which you open up the back cover of the galaxy s4 and then fit the prongs in place. Then closed the back cover and put it on my charger pad. The charger pad is powered by my OEM Samsung 2A output adapter so that should be plenty of power. There are two lights, one red that is constantly on which I assume is the power light. The other light is green, but it flashes. I'm not sure if it is supposed to do this, but pretty sure it is not as my phone will display a popup notification that wireless charging is enabled. One second later, the popup is gone and the battery icon no longer shows the thunderbolt charging symbol. Another second later, the notification comes back and the battery icon shows the thunderbolt charging symbol. So both the charger pad flashes and my phone's notification and battery charger icon appear and disappear every few seconds repeatedly, anyone know what is going on?
Kind of hard to tell without seeing which one you specifically have. Got any links? Have you made a good connection with the contacts on the back of the phone? And are you placing the phone in a good spot on the charger? I have 2 qi receivers like yours and I don't have these problems unless I'm using the official nexus wireless charger. I think the magnets in it do something to offset it. I have another wireless charging pad and I don't have these problems at all.

I actually do have the link: http://www.ebay.ca/itm/181216698737...eName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
I made sure to buy the GS4 i9500 and almost certain this is a right purchase as the prongs fit perfectly. Based on the instructions, the actual charger is under the symbol/icon, which I have tried to place perfectly. Heck, I tried so many spots with no success. I'm not sure if the receiver is faulty or if the charge pad is faulty. I'm looking into a ChoeTech and Incipio Qi charger right now as its around 30 bucks and have quite some positive reviews.
Well that thing is one of the thicker ones. And I've never liked the design of it. I'd definitely switch receivers. Then chargers if you problem still occurs.
1. check to make sure the contacts on the receiver are not getting disconnected inside the phone.
2. you need to find the sweet spot on your pad when you put your phone on it
Well, I'm in the process of getting a refund on eBay. Guess I'll have to go for a more branded charger instead of some no-name generic.
I've always used my note3 charger on my note 10.1 without issues and I'm very disappointed to see that the quick charger that comes with my note4 doesn't charge my note10.1!
When it's connected the red cross on the battery pops up (this usually happens when a low power charger is used)
Does this happen to you too or have I a broken charger?

No problems for me. I am using it to charge my Sony tablet-z with no problems.

My Note 4 charger charges my Nexus 10 without issues.
The Note 4's charger works on my Note 10.1 2014 ed. It obviously doesn't fast charge my tablet though.
The charger is SUPPOSED to act as a 9V charger when connected to Fast Charge devices like the Note 4, but also act as a 5V charger for any other device. If the device can't use the full 5V (like a phone that only uses 2V or something), the device itself will only draw as much power as it can accept under 5V (2V for example).
If your charger isn't charging your Note 10.1, then the charger could be bad, or maybe even your tablet's charging port. If the tablet charges with other chargers, then I doubt it's the latter.

I get the same thing. I have a note 10.1 and using my note 4's adaptive charger with the note 10.1 charge cable I get the dreaded red x -- meaning super slow charge. All items are in perfect working order (doesn't happen with other 2 amp non-adaptive charging chargers).

So it's safe to charge my S4, Nexus 7 2012 and S2 with my Note 4 stock fast charger? I remember some guy making a thread that it fried his S4...I've been cautious ever since
Do any of you have an issue where the phone screen turns on and off (and beeps) when it reaches 100% charged using a Qi charger? I am using the official Samsung wireless back cover with a Nokia Qi charging pad. When the phone reaches Charged, it will turn the screen on, then it'll say Charging Wirelessly 100%, then it'll turn the screen off and start charging... and the cycle repeats every 20 second or so. Anyone else?
I think it is standard glitch on all Samsung phones. The same thing happened with my old Note II, and it happening with my Note IV too. I have to shift phone maybe 1" off center so it would not make that noise.
Yes, I turn off notification and system sounds at night while charging with Tasker, and I use Gentle Alarm to display a dim clock so I don't get the screen flashing.
Thanks for the quick reply! Now I know that it isn't just my phone or charger, I can rest easier and just let it be (mostly will just take it off stand when charged).
My Note 4 is using S-View cover with wireless receiver built in + OEM Samsung Wireless Charger Pad (the big one) & I never experience your problem.
It only shows "Charged" once then fall asleep again until I turn it on.
this is correct if the note 4 is not properly centered ona single coil charger. upgrade to a 3 coil or center the charger coils with the base.
it takes place because the signal to cut off the charger at 100% is not properly received by the charger base so the charger keeps charging. the note 4 assumes the sginal sent will cut off charging and goes into a no charge state. then when current keeps flowing through the coils it wakes up and issues a no charge command again...which is again lost because the coils are too far apart. and the cycle repeats.
solution is to switch to a 3 coil charger or align the coils with each other.

Is there a way to find out how many coils in my charging pad?
First day with the classic, I got home just now and have my spare moto 360 charger sitting on the desk. Put the S2 on there to see if it would charge, it sits just fine and I would imagine that it's lined up but it appears that it charged it for a second and then doesn't continue charging. The 360 charger will remain lit as a device on there is being charged but the watch doesn't accept the charge. Anyone tried it with any other Qi chargers? Don't tell me it's some proprietary crap.
Havent had much luck with my Gear S2. I have to take the straps off to get it to lay flat on any Qi pad. Official Samsung Qi pad will charge for a second or two before it starts flashing blue and the watch stops charging. The cheap pad I purchased from Amazon doesn't do anything at all when I place my watch on it.
So I took apart my cheap charge pad and took the coil out. If I rest the watch directly on the coil it actually charges but it gets very hot after just a few minutes. Guess we have to wait for Samsung to start selling new docks or for a 3rd party to make one strong enough to power the coil in the S2.
It would seem that the S2 does not actually use Qi, or some proprietary variant. For me it's charging neither on the Moto 360 charger nor on various Qi charging pads from Ikea that I have.
Not my video but this guy says it works with moto 360 charger

It doesn't, and the video does not prove the opposite. It just shows that someone places a S2 onto the Moto360 charger and that charger and S2 recognize each other. This is what everyone can see, but as said, the S2 is not charged actually.
I would comment on the video if it wouldn't require G+ membership.
This one shows a guy using another wireless charger.

And that guy is as stupid as the other one because in his video you can even SEE that it doesn't charge!
BTW, he's also just as stupid as his Swabian dialect. And yes, I am allowed to say that, because I'm from Germany as well.
Just have a closer look, especially when he places the S2 onto the Samsung charging pad. You see how the charge indicator icon on the S2 appears and disappears right away. Then he swipes down so that you can see the icon again. And now you see that the little flash in the battery icon (which is on when the watch actually charges) is not there. So no charging.
Just because someone is able to upload something to YT does not mean he/she is right. Or smart.

Strange, mine works perfect ...
My watch just fits in the handle (facing 90 degrees) and the straps are touches nothing.
What handle? What charger are you using?

The standard charger that came with the s2.
Maybe it wasn't explained well. The watch just set nicely on the charger vertically and laying against the charge part of the charger. The strap is not close to anything ... not even close to an issue

They're talking about using the s2 with other qi chargers. There's not a problem getting it to charge on the included charger.

So... Yeah. It looks like everyone just assumed it would support Qi, since that was the standard that Samsung supported before the newest phones released this year (that supports WPC and Qi).
Looks like they may have went in a different direction entirely with the S2. This just gets better and better...

Unfortunately they didn't state what's the reason why standard Qi chargers don't work. They just confirmed they don't work...
Nice find anyway...
@chemaster: You might want to re-read the thread...
I'm not saying you guys are wrong about the charger but the manufacturer is supposed to say use with the supplied charger only. But here is a reviewer on AC that says the charger that came with the s2 is qi.

haha yeah i am from austria and i loled.
just got my gear s2 today and tried it with tylt charger, although just holding it against the back side and trying to find a spot where it will charge. but it did not. i also got the fast wireless charger from samsung today and it seems to work for a few seconds and then loose the connection and stops charging. sometimes after more than 10 or more seconds. so maybe it just recognizes the charger, but it seems like it gets a charge for some time and then stops.
i have a few other qi chargers at home from ikea and other and will try those as well and will report back. would be awesome to have some more options to actually charge the watch than just the charger that comes with it and no replacement to buy from samsung.
that was one of the best things of the sony smartwatch 3, to charge it anywhere you could possibly imagine.
Edit:
so i just got home and tested all of my other qi chargers. the ikea lamp charger does not work nor does the adata CE700.
but i noticed one strange/cool thing: the original nexus charger for the N5 in fact does work perfektly. i put the watch on and they connect and stay connected and i just saw it charged from 95% to 96% so far no heat or anything.
so i guess its qi compatible after all, but i don't get it that some or better to say a few will work and most of them not.
cheers

Uhh this thread is about using a charger other then the gear s2 charger, but you said your using the stock charger? We know it charges just fine on the charger it came with we talking about using other QI or wireless chargers.
---------- Post added at 10:15 PM ---------- Previous post was at 09:57 PM ----------
I have both a moto 360 and gear s2. I have swapped chargers and my findings are as follows.
The 360 works great on the charger of the gear s2. it charges at normal speed and works without any issues.
The Gear S2 does seem to charger slower or stop and start charging when being placed on the moto 360 charger, but that all seems to be due to size. The larger diameter of the moto 360 holds the watch higher up on the charging pad. When I place a spacer to lift the gear s2 high up on the charger it seems to work just fine. I think it's all about placement.
And for those trying the stupid Samsung wireless charger and getting a flashing blue light. It does that with the phone that's supposed to be on the charger and the is threads with pages and pages of complaints about that issue. I can only imagine that using this small watch on it will only make it more prone to do what it already does. So I don't want to even rate that!

No, it doesn't. The original charger for the Nexus 7 et al behaves exactly like all other wireless chargers:
It charges for some seconds then stops (in this case flashing a red LED)
I guess that the "sweet-spot" for charging in the S2 is so small (and elevated through the bent-down strap holders) that is could be charged on QI pads but doesn't due to its very (non-flat) shape... just my 2cts

i guess you are right about the sweet spot. i think its hard to find the right spot where it will charge.
but about the n5 charger (maybe you mean another one) i mean the magnetic square one. it will actually charge on it. i had to find the right spot, but it did actually charge. i can make a video if you want
Hi,
Well, I do have the same charger - square and with magnets in it. But I never managed to continuosly charge my S2 Classic.

So I got a fast wireless samsung charger from Sprint about 6 days ago. It has been working great but the last 2 days, after the phone sits on the charging pad for a bit, it's stop charging and the blue led light on the pad starts flashing. From what I read online, it's because the device goes into a sleep mode. Has anyone found a fix for this or having this problem also? I am planning on exchanging the wireless charger this weekend. I sure don't think it's my Note 5.
