Does anyone else see a black screen during sp3?

Only happens on my Samsung, been happening for a while now.

Yes, it happens since November to me. Same when i try to open crystals or level up a champ.
In sp3 at least the skip button is visible.
In openings, after a couple of seconds of black the image is back.
And in leveling champs, it's black out like a 3 seconds and then I can chose what I want to do
