Anything you can do to have the LED light to keep blinking until you turn on the phone?
The current setting only have the light blink for like 5 minutes. Far too short and too easy to miss.
Even to extend the blinking period to 1 hour is much better.
I had the Galaxy Note 2 and S3 before, and they keep blinking until you switch on the phone.
So I have the official wireless cover and a tylt qi changer and everyday in the middle of the night by bright ass note 4 wake be up to tell me it fully charged. How do I disable this??? Im rooted on stock Tw...
Wanam Xposed, Lockscreen section, "Disable Full Charge Notification"
IS there a way to do this if you are not rooted? I love my Panasonic Qi charger, but might return it for precisely this annoying reason - screen keeps turning on at 100%, stops charging, turns off, then immediately turns on in a few minutes because it's 100% again.
I never noticed this before tonight. I have the Samsung wireless charger so I assumed the light I was seeing from behind me (I have it on my bookcase headboard and the base lights up in blue while charging and turns green when done) was from that. Tonight, I have the phone physically plugged in and sitting on the coffee table next to me. The screen won't stay off while charging. I push the power button to turn it off, it goes off for a few seconds and then comes back on.
Is this normal? I have the screen timeout set to 30 seconds, don't have Daydream turned on (anymore) and Stay Awake is turned off in Developer Options.
I went and put it back on the wireless charger and confirmed that the light won't stay off there either.
If it matters, I'm running Rapture 2.1 (COF8/5.1.1)
Disregard. It was caused by Cellmapper.
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.
