ONI ... this appears on my screen, what is this?

I just recently started seeing ONI on an almost otherwise empty, blank, black screen while the phone is charging.

I also recently installed GoodLock ...  a coincidence?

Can anyone shed some light on this?

Thanks, Dave Horne - The Netherlands

Can you provide a screenshot @davehorne 

If you put the phone into Safe Mode which disables downloaded apps this should help to highlight if this is indeed caused by one of them.

I couldn't take a screen shot since this issue only appeared on a lock screen.

I also couldn't figure out how to put the phone in Safe Mode.

At any rate, I managed to 'fix' this issue but have no idea what exactly I did. 

I would be curious to learn if anyone else also has this issue.

If I can recreate this, I'll report back.
