Those of you with the Samsung LED wallet case: When you place/remove it from a wireless charger, do you see an LED battery icon showing on the front of the case at all? I noticed that I do get an battery and percentage icon when I physically plug/unplug the phone, but not when using wireless charging.
nope! the case uses NFC and might interfere with the coils used for wireless charging. You'll notice that the LED case needs to turn off for charging to start/work. Say you get a message while it's on the charger you'll see that the thing stop charging while the case lights up.

Hi
I've bought the standard samsung wireless charger and now noticed that there's always a blue or green led shining and I'd like to disable these as I use the charger in the bedroom.
Has anyone tried to disassemble the charger? How did it work out?
Cheers
Michael
Put a piece of electrical tape over it?
If you can open up the charger, I'm sure you can disable it. I feel your problem..
Lucky to have this at work which lights u only during charge:
http://www.dx.com/p/frunda-fct001-5...e-nokia-more-white-yellow-209238#.VUIa1SGqpHw
And the charger for LG G3 which have no lights at all at home.
putting something over it is probably what I have to do.
sadly I did not find a way to open it.. without too much of force at least and buying another one does not really make sense for me as I don't need 2 wireless chargers.
i find the Light extremely annoying i could not use the wireless charger at all during night time. please Samsung get rid of the light, there is an led in the phone which lights up already to know if the phone is charging.. do we need the bright blue green light in the wireless charger as well.. ridiculous
I have a strange problem with Dash Charging on my phone. When I connect the dash charger the blue light comes on and I get the bolt symbol. After a minute or two the blue light goes away and the lock screen does not say dash charging anymore. The notification icon however still shows the bolt symbol. If I keep the charger connected the battery percentage just sits fixed and does not advance.
When I remove the charger my battery will keep at the same percentage for a long time and then starts depleting. I feel like the battery is charged and it's only an indication problem.
This is a brand new phone with an original charger, I went to the retailer and he even changed the dash charger and cable and I get the same behavior with the second charger and cable set as well.
Additionally, if I charge with a regular non-dash charger my phone charges just fine. I get a red charging light and the charging percentage advances normally.
Please advise what to do?

I have this charger but on the note 8 (ok on S8+) it keeps giving me a bleep and the message "wireless charging enabled" pops up on screen every few minutes. The green charge light remains lit. Any ideas what is going on?
I've tried it vertically and horizontally and same effect.
thanks

I have one similar to that (amazon chinese one) and it will not fast charge on my note 8 but it will slow charge wirelessly but it doesn't oscillate and stop charging like you are describing. Works fine fast charging my note 5. Hard telling about some of those chinese wireless chargers. Are you using a samsung or equivalent qc 2.0 adapter? If so and it is still oscillating on and off it is a connection issue between the coils or some other quirk with the charger. Do you have another wireless charger that you can test with?

Hi Yes using the samsung charger. Its weird as the green light remains on suggesting its still charging but I get the bleep and message. I might bin it and buy a chotech one as it seems to have good reviews.
thanks
Hmm I'm not sure where the problem lies - I now have a choetech and a replacement for the other one I reported above. However the problem continues...
When the phone is fully charged it pops up on screen saying its 100% charged....then it seems to switch back to charging mode and again pops up saying its 100% charged shortly after.
This appears to be a constant cycle and rather than just keep it topped up in the background it tells me so...during the night this is a major distraction as the screen lights up each time.
It doesn't do it via the USB cable.
Anyway to disable the notification? Its not an app so can't find the permissions.
thanks
I'm curious about the technology inside the LED Cover - what powers it? What's behind the display tech? How does the phone send it information?
Does anyone have any insight? I figured NFC explained most of it, but I was surprised to see that it functions fully with NFC being on.
The case gets power from the phone in similar way as wireless charging, or s-pen and those LEDs don't need much. I think it uses NFC for communication and I suspect there are some magnetic sensors that trip and let the phone know the cover is there, so NFC switch off maybe just mean it won't communicate with anything else, but cover.

So I guess some sort of conductive power method? I didn't even think of how the s-pen works - it's more than likely the same method.
Magnets
For clear view LED cover you will notice a round thing on the cover. It is a magnet. On the back cover also sme magnet.
LED works by magnetic induction.

Actually NFC works with the cover on, but only when the cover is open - ie. phone is unlocked. I have no problems with pairing my NFC headphones with the cover on.
Does this mean the wireless charging in the note 8 goes two ways?
Not only can it be used to receive a charge, but it can provide a charge, too?
Are there any other mobiles that can do thee same? Or is it a common feature?
Its using NFC which has a small wireless charging component to it -
The NFC / paywave function on your credit card recieves a small amount of power which powers the chip and they can communicate at 13mhz.
The power supply can be up to 2.3 volts at 6 milliamps. Thats enough to power a few tiny LED bulbs.
As with all wireless power, it is incredibly inefficient and so i see it as just a battery drain. Probably would have been better to use a semi opaque window in the case which just shows the phone screen and positioned a clock to show through, building on the Always-On Display feature.
I've been using the LED case for several months now and I did not notice any significant battery drain. Keep in mind the LEDs only light up when you either hit the power button, close the cover or when a notification comes in. They never stay on for more than a couple seconds. Also note that when the case is closed, the AOD is turned off, saving whatever power those pixels are consuming. So AOD always on vs. a few inefficient LED's on for a few seconds. I'm sure it all depends how often the LEDs are turned on as to whether you consume more or less power.
As for just having a window, well then you would not have the touch gestures on the case itself. You can answer or dismiss a call by a swipe on the display of the case.
One thing I noticed when using the wireless charger is that charging stops once the LED case front lights up. Charging resumes once the LEDs disappear.
It's a flaw. Everytime I must flip open the case to do wireless charge.

Probably via the wireless charging pad on the back of the device. Or via the electromagnetic grid that powers the S-Pen

NFC Headphones?

Yeah I have some too - bluetooth headphones that are NFC enabled so you can just tap to pair them - Mine are Sennheiser Momentum Wireless
It get conductive energy like the spen... Spen working via NFC LOOOOL. You guys are funny

The S-Pen gets it power from the electro-magnetic grid that is under the display. But it has to be close enought to the display to receieve a charge.
Sadly, Note 9 display won't react when hovering over screen with spen finger.. i remember it worked in old days. anyone can explain technical difference?
i have a note 10 plus and two led cases after the last update both cases work but make strange symbols ..... did reset the phone but nothing changed....
What's the trick to allow the Note 9 apps to function while it's wirelessly charging? Currently, the phone won't even charge when wirelessly docked unless I lock the screen or enable Daydream.
Is there a hack that can fix this arbitrary limitation?
There's no hack. The Note 9 functions just fine while wirelessly charging. You have a bug.
Thanks for the quick reply. So, you can have an app like YouTube running on the foreground full screen while your phone is fast wireless charging?
Mine DOES show that it's charging in the notification bar, but the red led on the phone doesn't turn on unless the phone screen is locked. So, it looks like it's charging, but it doesn't actually charge the battery. When doing searches on this issue, I just see others asking the same question without a solution.. even for other Android phones.

Mine charges just fine while using it. I often put it on the wireless charger and watch Netflix. Of course using it will slow the charge rate, but it should at least keep up with the use.
Does your red led for charging stay on for wireless charging while watching Netflix, etc? Mine turns off unless the screen is off.

No that light only stays on while the screen is off.
Your get the same thing when using wall charger, indicator only turns on when screen is off since it's a notification LED. It isn't meant for it to stay on while screen is on since you can see battery icon showing its charging.
From what I've experienced, the phone will charge wirelessly, with screen on (about 800mAh) and wirelessly fast charge (I cannot get a mAh measurement, because the screen has to be off to get the "fast charging" toast message seen on the lock screen) with the screen off.
This seems like an odd limitation to purposely install, but there it is.
