No, all of my device's animations are turned on, and at the default speed.
I found a gif showing exactly what happens with my phone. Look at the Galaxy Note 8 on the right:

Notice how it lags for a bit before rotating back to portrait and going back to the home screen. While on the iPhone on the left it just goes directly into the home screen. Is there any way to mimic this? I mean, remove the rotating animation (with an app or something like that) so it just goes straight into the homescreen?
