Welcome to Android Central! Do you have any other lockscreen apps that were previously installed?

It is happening to me too since upgrading. Has anyone an answer?

I found that the camera flash on ring notification is the culprit on our nexus 5. I disabled it and it works fine now.

I'm not familiar with that setting--is that on a stock Nexus 5, or are you using a 3rd party app?

I have the same issue. I've tried to increase the sleep duration from 1 min to 2 mins and it didn't do the trick.

When I Sideloaded the APK file, i had this issue and after an attempt to re-lock the bootloader - the issue went away and now it's back again. I am not sure what fixed it but appears to be a configuration of sorts to be broken as the issue re-appeared.

Did any one have any luck with this?

I can't find any Flash notification in Accessibility settings (that's where its supposed to be) on Lollipop on my Nexus 4. I know that iOS has this feature as it doesn't have a notification indicator.

Update 2 -

Guys.. Looks like some others on Nexus5 Lollipop have the same issues and found the culprit.

If you're using Velis Auto Brightness then disable it for now. There appears to be some bug that has been acknowledged officially

And I believe a fix is on the way.
