I tried out Android 11's built-in screen recorder... trying it on Blue Archive.

It. is. mindblowing. Not only Shiroko's animation, but also the smoothness the recorder managed to get. It is important to note that uploading it as is to YouTube doesn't work that well, so a trip to HandBrake it is.

I installed Android 11 on my new device using custom ROMs, because I am just so used to the vanilla Android experience.
