Is it normal to have iPhone 10 gestures on an iPhone 7?

I recently bought an iPhone 7, but sometimes I can for example open my task manager by putting pressure on the left side of the screen. If it helps, I have the newest update. Is that normal? Is it a part of the new update? Or is my phone just glitching?

Gestures are specific to the iOS version.

That's normal. Part of using 3D Touch.
