Hmm, sounds like it's probably the Pixel Launcher doing some trickery then. If you install this app, does it have a circular icon as well?
I'm on Android; this one:

IIRC, it changed zeros in my code to periods. You just need the numbers at the very end.
I'm horrible at receiving morse visually, it'd be so much easier for me if it was audio, but unfortunately that's not how they put it in the game.
I did a ton of those in the past when battlefield 4 first came out, and I know that it eventually gets to a series of numbers, but your video didn't have that part. Also, I heard that it has to be done in one session, so if you closed the game after your recording, the numbers could be different the next time you go in.
I suggest this app on your phone to decode it reliably. https://play.google.com/store/apps/details?id=com.blueta.morsetransmitter

I'm on PS4 sorry! Here's a couple of EE servers though
Here's the Morse code app that's pretty useful! https://play.google.com/store/apps/details?id=com.blueta.morsetransmitter
It's not on iPhone so if anyone wants it doing for them I can happily, just comment a video of the morse code once the light sequence is completed.
/u/fanny_bandito there are also apps for it
