Blue light filter randomly turns off on S9+

[blademagic]

Hello,

I was redirected here from the US forum, so I'll paste my original post below.

"I recently bought a galaxy s9+, and a really annoying bug is that when I turn on the blue light filter, sometimes it just turns off by itself. I have the schedule set so that it turns on automatically at 12 pm, and turns off at 6:45 am. However, sometimes I am in the dark and turn it on manually. It would randomly turn off even while I'm in the middle of using my phone! Just now, I forced it on again after it turned off by itself, and literally 4 seconds later it shut off again. What is going on with this? I've attached a screenshot of my phone jnfo. Please help me figure this out."

I've tried clearing the cache, but that did not work. Is this a bug? I've attached a screenshot of my phone specs.

I don't think that it's a bug - But if it is - I've never experienced it on my S9+..
It's possible that the schedule you set is overriding the manual Toggle on or off... Do you have any other Battery Optimization set up?

Thanks for the reply, shaggy. I am not too sure how the internals of the software works, but the times that this happens is nowhere near the times I set up for the scheduled times. i.e. scheduled to turn off the filter at 6:45 am, but it randomly turns off even when I'm using it at 12 am.

Maybe you can help shaggy?

Go to App manager in settings, go to the three dots and look for bluelight filter> clear data>restart phone.

I had this issue with my Note 9 before.

Thanks ctangabc, I will try this and will update the post on whether it worked or not. It might take a while before the issue pops up again though, so hopefully, if this doesn't work, I will find out within the next couple of days.

Okay, so I did this, and it just happened again. I think this is seriously bugged, perhaps something with OneUI itself. Not sure of any fix right now, so if anybody has any ideas, please let me know.

Sorry, if the fix doesn't work for you.

Please don't be sorry. I appreciate your help, so thanks for trying to find a solution to my problem!
