My friends dad almost took a pic, but it "glitched" and I tried to show him something, he got angry and said he was going to block me on instagram

So I 23F was at my friends 24F house and I was talking to her dad 50's M. I jumped out of nowhere and kind of scared him. He told me to hold still for a sec while he uses his smartphone to take a pic, I told him "no, don't do that". He did it anyway and I saw it happen in front of my eyes, the majority of the background around him went super blurry, and everything froze for a split second like a *glitch* then the camera app froze, he tried opening the app again and it shutdown. He got super angry and said "what did you do to my phone", and I said "glitch in the matrix", and he got offended... I was trying to do a prank, but it got out of hand.
