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

Costume led notification

So I tried light Flow, but it only works once, I mean, that, if I say that I have to blink 3timez, it wil blink 3times but is doesn't repeat after that. Annyone the same problem? Other solution?

I have a problem, with the new firmware .253 i think my led doesn't work because the only light i have is colour WHITE... (with stamina or without stamina)

[Q] How to completely disbale LED lights even at the start of Music?

Does anybody know if there is a way to completely disable LED lights? I have turned off all Light effects but even then the LED becomes On on the start of a song or when a song is changed. I want to completely turn it off. plz help

Try deleting sys/devices/i2c-10/10-0047/LEDs file. You should make a back up first. This should completely disable led lights

My WhatsApp is set to green and the phones flashed green whille locked...

As far as i know, it's normal behaviour due to STAMINA MODE. Try it, without STAMINA MODE and it should blink with the color you set in Whatsapp.

Thank you. Deactivating stamina mode took care of it. My battery life wil decrease though, there's no way for it to work with stamina mode enabled?

For now there seems to be no other solution. Even trying to use third party apps to control LED Light&Colors (available at the play store) seem to fail, to withstand the STAMINA MODE, putting them on the whitelist won't help neither
You can use Greenify instead of STAMINA MODE. If you are rooted it will work automatically otherwise manually.

What is it with Sony and the LED?! hahaha seems like they think it consumes lots of power, it's just a tiny led! on the Xperia Z it didn't flash at all when Stamina was activated.
