Screen randomly glows when screen is switched off

Hey on my Xperia Z stock rom nothing flashed, when it is in standby (screen off) randomly the screen glows and does not stop, like the screen is still off but it's like the back light has come on? is this normal? seems to be a power wasting thing to me. unless i look at it from a slight angel (during the day) i can not actually tell it's on, i'm assuming this is why my screen is using 60+% of my battery is there a fix for this?

Are you using any power saving mode?

Stamina mode.

I have the exact same thing happen, and it is definitely a pain as like you say you can only notice it when looking at an angle, and as I have a flip case on mine I only notice while charging. It is just a case of pressing the power button twice to turn off but that is obviously only when you notice it's doing it! lol
I use stamina mode on mine (which is great) but not sure if this is anything to do with the backlight being left on as it only does it sometimes?

I had this issue when i first got my phone ,and not anymore.Not sure how it solved cause i did lot of factory reset and flashing firmwares.
Are you using light flow or any third party apps?

I get this too. I get it when it's locked and it comes back on. Also when I unlock the screen sometimes this happens and I have to turn the screen off and on again to fix it.

Happening here also but not often. I thought it was low battery mode but happens when it's disabled as well.

No i'm not using any third party light apps, seems like this may be an actual bug if multiple people are experiencing it
I have only done one reset/repair to fix the LED notification light bug.

Hope this helps
I know how to fix this. I have an xperia z1 so im not sure if my problem is the same but i use my phone as an alarm so i notice at night the screen is glowing while its standby. If you go to settings or maybe you have it in quick settings go to brightness and deactivate "adapt to lighting conditions" then it should be a black screen woth no glow in standby mode

that's probably how stamina mode is supposed to work, if you want clarification contact sony

Is it possible to haveLED Notifications on Stock HTC One like CM 11

When charging on Cyanogenmod the leds flicker between amber and green when your have a notification. Unlike the stock htc one whch doesn't, it just stays on constant amber until its charged then it stays on constant green.

I'm pretty sure my HTC does the same with stock. Correct me if i am wrong?!

It seems like a pretty heavy app to just change color. Why are permissions list so many?

notification led stuck magenta

Something weird just occurred , I was using the shop Samsung website and whenever I pressed the back button to go back one page I noticed a blue dot blink in the middle of the screen. Didn't think much of it, but then was in the BBC app and similar red dot appears on the middle of the screen when opening a sub page withing the app.
I rebooted my device, now the led notification light is stuck on a magenta color, any ideas ?

Annoyingly sometimes the LED will blink blue if Samsung apps need updating

Do the LED test by dialling *#0*#

Seems to be working after a reboot. Was thinking maybe Samsung were employing some sort of low level fault indicator with the light being stuck on a certain color.

LED color?
Sorry for hijacking your thread, does anyone knows whether the LED has some sort of bug? I changed LED color in my Whatsapp but it always either not the color or its either blue or magenta.

No worries. WhatsApp always did that for me.

Led Indicator color issue

I received Note 9(VZW) directly from Samsung 3 days ago. I traded in Note 8 and received $500 credit. It is my first purchase from Samsung.
Everything works fine except the LED Indicator. I don't see any problem with Red, Green and Blue colors. I noticed the color of KakaoTalk notification LED is not solid yellow as it should. It looks like light green(half yellow and half green). If I let it blink for a while, it sometimes changes to Yellow and goes back to light green. I installed "Light Manager" and tested all available colors. I see a problem with Yellow, Orange and White. Yellow looks like light Green, Orange looks like Yellow and While looks like light Cyan. If I them blink for a wile, the correct color of Yellow and Orange sometimes light up. However, White remains in light Cyan.
I think my Note 9 is defective. Has anyone exchanged a defective phone from Samsung? What process do I need to go through? Do they send you a new phone 1st like VZW does?
Thanks.

Couldn't even get light manager to work on my device. It said that screen must be off to test the led colors. If screen is off how the hell do I press the on screen test color button [emoji23]

That's because you have to turn screen off once you press test mode or W.e it's called, wait a few seconds and notification light will start to flash.

I use LED Blinker Pro and it works perfectly ?

Yep orange and yellow look about the same on mine too. Meaning when I pick orange it's yellow and orange and when I pick yellow it's orange and yellow also. You best exchange yours, not acceptable for $1000+ device [emoji23] [emoji1787]
PS. I remember all my previous notes were similar. Good luck.

I am having this same issue too when I use light flow. I need to know if it's a defect or if it's something the app is doing. Doesn't seem as though that many ppl are having the issue or even notice? The phone is fine otherwise. Can anyone else verify if this is happening? Anyone with two devices?

I have the identical problem as the original poster, with exactly the same colour issues.
The bizarre thing is, this has only just started to occur. The colours were pretty well defined before, other than the white which was always a little cyan looking.
Last night I was expecting a yellow LED from a notification and I got green.
I then tried all colour options in Light Manager and it seemed I only got red/green/blue despite what I selected. Same with defining custom colours in Whatsapp.
I experimented and set the LED to BRIGHT in Light Manager. Was previously on Normal. This improved things massively. All of this was done in evening time indoors with not much light.
Today I re-set the LED to NORMAL in light manager, and the colours were fine. Also the Whatsapp colours were now ok too. This confused me, but I read on Light Manager forum that this phone has an ambient LED sensor so I am wondering if that is what is affecting the colours. I will try again tonight in the dark and see if they have reverted back to R/G/B again.
So my solution at the moment is to set the LED to BRIGHT in the Light Manager settings.
Not ideal really as on my S7 previously the LED was faultless.

I had an note 2, note 8 and now note 9 and they all have the same issue with some colour blending with that LED.
It must had some multiple fixed colour LEDs around the hole and the green and yellow must be "far" from each other so that when it need to mix them to make the desired colour, they badly blend.
