Is my phone infected with spyware? something else?

Hi all. Recently (As in the past few hours) my iPhone 11 has been glitching out. A few notable events of things being weird:

• I received a 15 second long voicemail from an unknown, non-local number. However, i did not receive a missed call. It wasn't a telemarketer as the voicemail was nothing but silence.
• I was browsing on safari and when I went to click a link on a legitimate news site, it opened up a completely different website for a missing child. When I closed the tab and reopened the original link, it worked fine and pulled up the correct destination.
• While also using safari, my apps started to randomly and sporadically jump between each other. I eventually was able to start a screen recording so that I could demonstrate what was going on. Towards the end of the video, I am attempting to slide down the control center to stop the recording but it keeps shooting back up. That was the only time i touched my screen during that video.

I recently dropped my phone and now have a few cracks in the screen, but nothing major. Is it possible that the damage is causing the screen to act so oddly? Or is my phone cloned?

There might be a simple explanation for all of this, so I apologize if I am missing something obvious, but I am a bit worried that I am being spied on.

Thanks for any help.
