Tmobile note 4 LED light options & Notification recommended apps (earphones)? - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

Hello all;
I just got my Tmobile Note 4 this week and updated to stock lollipop right away. I came from Canadian GS5 which has both the LED light options (for low battery, voice recording, etc...) as well as Notification Recommended Apps for earphones when my headphone is plugged in. I see that stock Tmobile Note 4 lacks both of these (there is simply a check box to enable / disable LED light all together). Is there any way we can enable these features? Must I root and risk tripping Knox?
TIA.

framework issue on note 4 tmo

Hello:
I've noticed that when I have xposed installed (only have xtorch,greenify and no volume warning) it breaks functionality of my note 4's privacy mode. Any fix for this?

[Q] LED light on stock

so... I've had my N6 for about month and a half and last week decided to root, weird thing was, I DID NOT KNOW that there was a LED light on it ... while using stock, the LED light did not come on at all and only when i installed CM12 that i seen the light.
I want to go back to stock but i want the LED light for notifications. has anybody encountered this problem? how do i fix it ?
Stock does not support LED.
For me this is not an issue, why would I want an LED always flashing to show me I have notifications.
Went through the trouble of installing CM12 and you want stock?
Unless something was missing in CM12 like flaky bluetooth I would stick with custom ROMs

You don't want the light but i do ... preferences ...
installing wasn't trouble at all, my problem is that i feel like cm12 needs to get better and less buggy, the rom just started coming out so I wanna wait until most bugs are fixed, I was enjoying stock for a while, just wanted to test out cm12 to see where it was and for the way I like it, it's not ready.

does it require root?

Yes it does require root and you need the paid version of the app. I cannot believe the N6 didn't come stock with led notifications and double tap to wake. Beside the washed out/ way over saturated screen, I think I might return mine to ATT before my 2 weeks are over
Can't complain... Its huge but I kinda like it
Yes I was shocked at the light too.
Definitely should be enabled out of the gate.
Unlike the TINY one behind the HTC speaker grille with very limited viewing angle this one is bright and actually better IMO than Samsung's.

One thing to note is that for now with Light Flow the only colors for the LED are red green or blue. Or if you manually change the color with the built in light flow mixer you can make strange combinations with the top half of the LED being one color and the bottom half another.

IR led allways on

Hello guys , i noticed the the infrared led from the proximity sensor is always on, even with the screen turned on. Isn't it supposed to turn on only when you make a call ? or when you use face unlok ( but it's non my case, since i don'e use any lockscreen )
I have an another samsung device, an galaxy s9, and the led turns imediatly off when you pass the lock screen or you end a call.
This is my second Note 9 device, both had the same "problem".
I uploaded o video on yuotube, i cant post the link since is my first post. But you'll find it on youtube " Samsung Note 9 IR led allways on "
Thx
Mines off after face unlock is used...
Took picture with another phone to see if it was on, it wasn't...
Might be something wrong with your Note 9 or an app you are using might be causing this, especially if it's a problem that has migrated across 2 Note 9's...
This is my second Note 9, both with the same issue, and the odd thing is that this morning i chatted with samsung chat assistance, and they claimed that even their test model had the infrared led allways on , and that it's normal to be like than ! In my modest opinion, i think that it'a bug (related maybe to the exynos models ).
I do not know whether to keep the phone or to get a refound.
The infrared LED is on when auto-brightness is enabled to detect light, turning auto-brightness off will turn off the LED

I assume OP is not refering to the infrared flood light used during iris scanning
It's the smaller LED near the proximity sensor, visible with a camera or something that detects infrared-light
Gsam used to always show high proximity sensor usage on both my note 9 and note 8 . I turned off smart alert and usage dropped by 90%.

I'll try to switch off smart alerts to see if the situation improoves. Since now i tested 3 samsung models: s8+ , s9 and mine note 9, all with th same settings , and only mine keeps le infrared led on .
With my first note 9 i tried a factory reset, reflash fw with odin , but with no luck, so i asked the seller to change it with a new one. And even this one has the same " issue" ( if we can call it like that )
I like the phone but knowing that i have a infrared led allways on in my eyes , it's bother me.
By the way i have the exynos version.

Blue Light Sensor and Blood Pressure Sensor?

Hy people, I would like to know more information about this strange Blue Light Led/Sensor in the back of the Note 9.
I own my Note 9 since 2019 and a few weeks ago during test with an app called MY BP LAB that was supposed to measure blood pressure, I saw something that I never saw before, a bright blue light coming from a led in the back of the Note 9. More precisely between the red led ( heart pulse sensor) and the flash led.
I experimented with several health apps but I never saw this blue light turno on in all this years.
Why this is the only app capable of tapping on this hiden feature?
Why this feature is shrouded in mistery? I can't find anything about it in the internet, except one picture that direct to some superficial description about the My BP Lap app.
Does you know something about it?
Is there other apps that use this feature?
Is there a way to turn it on/off?
Thank you a lot!

Is is measure accurately?
BP lab doesnt give actual blood pressure result, just % increase/decrease compared to your "normal" level, which you have no idea to measure either.
kinda useless app. but im curious about bluelight sensor of Note9 too. no other app could activate this light so far, even the samsung apps.

Exactly, from what I tested the readings are not correct, they are always too low compared to two BP readers I have.
I am still curious about this blue led and other aplications it could have. And I also make an UPDATE, there actually 3 leds, red, blue and also GREEN.

Question Edge Lighting Not Working?

My faithful Samsung S5 Mini finally died and still getting head around quite a lot of things as I've only had the phone for a few days but for the life of me I cant seem to get the edge lighting to work...
The phone was on Color OS 11 but auto updated to 12 (CPH2173_11_C.46), unfortunately I never got the chance to test it on Color OS 11 so don't know if it ever has / did work.
If I go Settings > Personalisations > Edge Lighting there is the option to pick one of three colours, this shows an animation of a simulated effect but doesn't demo it on the actual screen.
Found a few guides online but they seem to be for Color OS 11, the menus are different and many options don't exist any more - I have reset the phone phone as recomented when upgrading to a new Android version but this has made no difference.
Pretty sure It's something simple I've missed like some obscure notification setting but compared to the S5 Mini its a whole new level of complex lol
Rather randomly the AoD works fine, just not the edge lighting.
Thanks in advance
Do you have "wake screen when a notification is received" on? This might disable edge lighting.
The edge lighting is poor anyway, it only flashes twice so blink and you'll miss it.
Plus they massively reduced the options in 12 so it's pretty hard to see. Big backwards step IMO.
Thanks for the reply. Checked the settings and got the mrs to send an SMS whilst i hand the phone in front of me, as you said it flashed twice and that was it - looks like a typical case of operator error as I was expecting it to work in a similar way to a good old fashioned notification LED and flash until the notification had been cleared
Will have a look around for a half decent app that offers something close enough to how I was thinking it worked.

Oh no they don't work like that, in my Samsung S10, the edge lighting worked in similar fashion as the Oppo. I would imagine it would take too much energy if it were flashing until you cleared it (say if you get a message while you are sleeping). Maybe AOD is the better alternatives as you can glance your screen and see any incoming messages or missed calls, and even that, they figured it would drain battery too as now they have a setting to turn off AOD after prolonged period of idle.
I wish LED notification make a come back, but I'm not holding my breath for it.
I cant even get the Oppo to edge light. I have an app Always On Edge (or AOE) from playstore. This is worth the effort.
Fully cutomisable. Try it out.

You didn't miss anything. I've been on Oppo for years, Edge Lighting always worked until Android 12. Now it straight up doesn't do anything and it's very frustrating.

I'm facing the same issue after Android 12 update on my Oppo Reno6. I have already tried out all methods, but nothing worked. it's frustrating me.
