KwestJones We're currently investigating this with our specialists and need this information in order to align any consistencies that could potentially be causing this. We appreciate you providing this information and we'll be updating the thread with more substantial information once we have it.
For any new posters, or those who haven't already, please continue providing the model code, carrier, and baseband version of the phone.
But the problem is world wide...
This forum topic was my first result when searching for 'edge lighting screen off note 9' on duckduckgo.
I am going to hang around to hopefully hear a fix 🙏
FYI to folks in this thread. The Edge lighting has been broken since the 8.0 upgrade. It stopped working on my Note 8 and has never worked on the 9 I bought ... even though it's running 8.1.
They know this so giving your model, baseband and all that is meaningless. It's a known issue and affects every model in every country. It's something broken as of 8.x for this feature. Maybe it'll get fixed in the Android 9 update but then again maybe not.
Good news is, they just released an update for the Samsung messages app in the Galaxy Apps store and it fixed this bug. Trust me, it was driving me crazy not getting pop ups. I woke up one morning and the messages app had an update available. Poof, Edge Lighting started working again.
I own a Note9 and it is up to date with updates. My issue with Edge Lighting is different and just started, as far as I can tell, in the recent past. (Today is 4 Nov 2018.)
I have Edge Panels and Edge Lighting _turned off_ and yet I still see the Edge Lighting effect.
If I open Settings abd just click on Display, the Edge Lighting comes on and blinks twice rapidly in succession.
I am at a loss on how to turn this off. It also flashes on other occassions but I am tried of wasting my time on this. I wish Samsung would sort this out.
