Edge lighting won't work with the screen off

I've tried everything. It works fine with the screen on, but that's not really useful.
I have edge lighting set to "always", and I've selected the apps to use with edge lighting, but it still won't work with the display off. I've tried it both with and without the always on display on, too.
Any suggestions?

You're not the only one. Heard it is corrected and works with Oreo beta from a user in the Samsung community.

Mine works for text messages, but I can't get it to work for Gmail. Even with it set to go off for gmail, it doesn't. Maybe instead of waiting for Oreo, they should fix some of these things now.

Works just on Samsung text for me only.

That's frustrating. Could be months before we see Oreo. Why not just push an update to fix it now?

i had this problem before and to fix it just set the edge lighting to "when screen is off" then call yourself and see, if it works change it back to "always" and test

seems to work if you can turn on popup notification inside the app you want to use for edge light. whatsapp, telegram works for example. but I don't like that popup which appears when you turn on the screen..

You don't have the apps selected in edge screen to hide sensitive so content on the lock screen do you?

No I don't I only enabled Edge Lighting for Telegram and WhatsApp and both show the content in lock screen, but the Edge Lighting only happens when the device is unlocked/screen on.

That's the same for me with whatsapp. It's not a bug edge lighting doesn't work with all apps all the time

I wish it would work for everything too believe me. Some apps I have selected don't show even when the screen is on my whatsapp does and my text do but they don't show with it off either

Edge lighting only works for snapchat if the option to turn on the screen is enabled. It seems that edge lightning relies on apps to turn on the screens and interprets it as edge lighting.

I have the official Oreo on mt S8 plus, and it only works on screen off f I have popup notifications on.
I add that even with this, the edge lighting will not work on screen off when the phone is turned screen down, facing the table totally strait, it needs to be tilted for edge lighting to work.
This is USELESS, this is not only beauty and show off features, we do not really need it to work when the phone is on in my hand only.
Nowadays lots of us would put the phone on the table face down for many reasons, ring holder on the back, force always on display to turn off but still need to see edge lighting.
So it would be good feature to add which applications uses edge lighting when screen off.
This problem only occurs with whatsapp I guess, I tried it with Viber, and it works without popup messages, aith screen off and phone turned down on it"s face

Thanks mate... really bad to hear am that... edge stuff is a really good feature but if it doesn't work is really frustrating. Hope to Samsung fix this annoying issue.

Weirdest black screen issue, tried everything ....

Non rooted, T mobile branded 3 month old note 8. No water damange, no drops etc.
Using chrome one miniute, set the phone down to watch a movie on my tablet, picked up the phone to check messages and boom. Screen is off. The phone works, I can even answer calls because I know where the answer button is on the screen, haptic feedback works, all indicator lights work. The phone screen remains off.
Tried a soft reset (tried hard reset too the best I could being I cant see the screen) and the phone seems to reset based on the vibration and indicator light patters but the screen remains off. It's as if a physical connection between the screen and the brains of the phone has been severed. Literaraly the weirdest thing that has happened to me in a decade of Android phone ownership.
Googled all the black screen issues with these phones and most of them are resolved with just a soft reset... some said that the phone is in it's lowest dimmed state and go to a dark room and i'll see it faintly and then can increase brightness... no luck...
Has anyone experienced this?

I would say it's a warranty job, just tried turning my brightness to zero and you can still see the screen.
I did have a similar problem on an old note that had root and custom rom though but I had somehow set the volume rocker to control brightness and it had lowered itself to minimum in my pocket

Try pressing and holding Volume down and power button for 5 to 7 seconds to force power off, then try to boot to download mode Volume Down + Bixby + Power button and see if the download mode screen shows......if not then probably a bad screen.

so I had it replaced under warranty through T mobile. Refurb phone will come in today. One quesion. Should I let the Tmobile techs do the data/settings transfer from old phone to new one or just do everything myself from scratch (which will obviously take longer).

This happened to my phone twice for the past month or so. (both in Nougat and Oreo - Non rooted) Black screen but phone seems to be responding -- I can receive calls and notifications etc -- And force reboot doesn't fix it. I've also tried drainging the phone when it first happened to me but doesn't work. HOWEVER, it gets okay so randomly. Like I just left it for couple of hours and it just worked when I hit the power button.
I did tried bringing the device to Samsung but what they did is to just manually upgrade/reset the software in their end which I could have done in my part but I just let them do it. They told me to come back if it happens again which is kinda BS.
I can conveniently say this is a Hardware issue. I will wait for it to happen again on my phone and request for a replacement. Phone is 4 months old when it first happened.

I have the same issue with blank screen but phone is working.
It started couple of weeks after i dropped my phone on the ground. There is black dot on my screen and broken glass but phone was working ok and was still pretty usable. But then it started:
Display works fine but when i switch display of, lock the phone or display switched because of its timer it didn come switch on... But phone works, i can use it with blank (black) screen.
I had to do force restart so the display will turn on with samsung logo and booting screen, and keep on till another switch of.
I was trying every setting (but no hard reset) and then i found a little hack:
When you turn on the "Always On Display" (AOD) function you can let the screen switch off or do it manually, wait for 1-2 sec and always on display will come up to the screen. Then when you press home button or lock button screen will swtich on normally. YOu can type pin and use phone witch screen working. But when you try to unlock from "AOD" with your finger or your eyes it unlock but with screen black.
So i was using it like this. everytime you need to wait second untill AOD comes up, but it was working fine.
Problem nu 2 is that now it stop working, AOD is working but when i want to switch screen on from AOD it shows black screen and phone is working on blind.
So everytime after my screen goes black or to AOD i have to unlock the phone blindly and "Force restart" it and have to keep waiting until boot, and then have to never let phone to screen of.
Its not usuable.
¨
Now what do you think? Is it hardware problem or software problem? Because screen is working but randomly. The black dot of dead pixels on the screen is getting slightly bigger in time (about 1 year) but its like 1.5cm round. Maybe this cause the problem? And why hack with AOD was working for half a year and then stoped working? There wasnt any updates right before, but i tried to install some apps (non display related) so ill try to uninstall them.
Hawe you got any idea if i can repair it on my own even if i loose the waterproofability?
Or can it be replaced for free if i have a warranty? (I dont have insurance)
Thanks for your tips guys.

If you're under warranty it will likely be a free repair, unless they find other damage. Like moisture damage.
As far as fixing it yourself, it's just about as cheap to have Samsung do it than it is to buy the parts yourself. It's $229 for Samsung to do it, and you'll maintain the water resistance rating.

same has happened to me

This has just happened to my note 8 too. I was about to update it and had started it. set my phone down and picked it up and phone screen is black but can hear the haptic feedback.

I can only see the lock screen and the notifications. Everytime I try to unlock my phone I only get to see a glimpse of the notescreen and then the screen turns black. Even when I try to go to camera through the lock screen the screen goes black too. When I charge my phone it heats up so I haven't really charged it as well. Has this also happened to anyone? It seems as if the phone's sensitivity still works in all places but when I unlock it the screen just goes black.

I also have problem of freezings and always rebooting. Tried soft and hard resets/factory reset. Still same problem. This phone has hardware issue. Do not buy.

I realize this thread is quite old but I have this exact same issue now. I have managed to discover some other information by playing around with various settings which are noted below. To begin with, I was able to used the AOD hack posted above for a while but it no longer works. The only way I can get my screen to come back is with a soft reset - but as soon as the screen times out or i turn it off, it goes black, with or without AOD enable. All the on screen buttons still work as well as the haptic feedback - I just can't see anything.
Now on to what I have found:
One thing I have found is if I turn off adaptive screen brightness and crank the brightness slider to the right, when it goes black I can faintly see some of the buttons - enough that I can turn the phone off or restart it from the power menu (If I switch the default setting to night that also helps to see the buttons a bit better). Also, if I enable night mode I can also see the brightness slider faintly but when I slide it left, it just makes the screen completely black and when I slide it right, it only returns it to the very faint brightness level.
So at this point I am stuck. To summarize the issue:
1. When the screen either times out or turns off, it is still "alive" but goes black. It will not return to normal brightness.
2. Turning off adaptive brightness and cranking brightness slider to right allows you to see faint buttons after screen times out but won't return to normal brightness.
3. Enabling night mode helps to see the faint buttons, in particular the brightness slider a bit better. However the screen still cannot return to normal brightness.
4. The only way to get the screen back to full brightness (albeit temporarily until the next timeout) is to turn off the phone or reset from the power menu; or soft reset holding volume down + power simultaneously.
Hopefully someone else has figured out a way to recover this. I am on Android 9 with Samsung UI 1.0
Phone is completely stock, never rooted and completely out of warranty.

Edge lightning showing only icon and default color when screen is off :/

Hello, my edge lightning works just fine when my phone is on. I get a pill and edge lightning. But when the screen is off, the only thing I get is a pill with and icon and a blue color no matter what app triggers the notification. I searched a lot but could not find anything. Thanks a lot in advance.

Better than me, only stock apps work for me. WhatsApp etc it doesn't work if the screen s off.

I am willing to even root my phone(which i dont really want) because everytime i have notification I have to turn on my screen :/

im new to edge lighting so im not completely sure how it works. for me all it does is glow around the screen once i get the notification and thats it. so unless i see that i really have no way of knowing i have a notification still active.

Most of us can't ever get it to work with the screen off. Edge lighting is a trip

Edge lighting works fine for me with both screen on and off. Those of you who cannot get it to work with screen on or off or both. Should try doing a factory reset through Odin or something and see if android version you got could be corrupted or damaged that causes the problems to some functions not working

Edge lighting not working

I recently got s10 and I am new to this Samsung UI and was excited to try the edge light feature but soon I found out that it doesn't work properly. It works when the screen is on but doesn't work when it's off though the mode is set to always. Then I read some forums and found that it's a issue with Samsung phones for a long time that edge light don't work with screen off. If I recieve a text message then it will work correctly even with screen off otherwise it wont. Any solution for this

Activate proximity sensor during call in my app

I'm developing app for WiFi calling.
I want to turn off screen when proximity sensor reports "near". It work fine on other phones but on S10 phone looks like proximity sensor is not even activated - there is no white dot blinking on top part of the screen.
If I make normal call or use WhatsApp dot starts blinking as soon as I start the call.
So what do I have to do in my app to make that white dot blink on Samsung S10 phone?

I'm not quite sure, but there seems some kind of known issue with the proximity sensor that dates back to at least March. Screen coming on while in your pocket, screen not lighting up when pulled back from your face during a call, screen randomly coming on while on a call, despite it being pressed against your ear/face. I've tried everything suggested and the issues remains, unfortunately I'll be returning my S10+ and going back to my S8+, pretty disappointing for a $1,000 phone.

It's always recommended to do a factory reset after an update, problems happen not only on Samsung, even on iPhones, not a big deal.
Try this?

During normal phone call my sensor works as it should.
I just don't know how to activate it in app that I'm developing.
On all other types of phones this is not a problem, since this sensor is always on. It is just S10 series that have some kind of special sensor which have to be activated. You can see white dot (left form the front camera) blinking during call... that means that the sensor is activated.
The only other app I saw apart from phone app that can activate this sensor is WhatsApp. It activates it during call or during listening to voice messages.
I also checked Google Duo, Messenger Lite and Linphone app and none of these doesn't activate sensor. So it must be something that WhatsApp knows and others don't.
I also asked this on WhatsApp support, but I was ignored of course.

Do you find how to activate it? I have the same problem in my app and it looks similar on new Samsungs (I find it out on Galaxy Note 10)
Thanks for replay.
