Today out of nowhere I noticed my phone make pause when I tap to open game (like 2-3 seconds pause before it launches it, it wasn't happening before) and then when I try to record gameplay with game tools it freezes and after 10 seconds says 'Couldn't record video, try again' or something like that. Yesterday it was all fine.
Yes, I tried clearing cash and data and reinstalling both game and game tools and no success. Additionally, I did factory reset 5 days ago and everything worked fine until today.
It's Exynos version Note 8, dual sim one.
Android Pie.
It's not rooted or modified in any way.
Here is video of problem:
