Three Mysteries (Two Solved, One Pending)

This won't be my most lucid sentence-writing, and you will learn why soon enough-- but I was involved with three mysteries today (so far) and while two of them are resolved, I'm going to need your help with the third:

1) I just finished Anthony Horowitz's mystery novel The Sentence is Death, which is fantastic fun . . . except for the ending . . . not the actual ending of the book-- that's compelling and full of twists and turns-- but my experience while reading the ending was quite unpleasant;

2) this afternoon, my wife and I took a walk at Rutgers Gardens and the weather has turned-- it's hot again-- and when we got home, I wanted to take a nap and she wanted to watch TV so I went upstairs to our bedroom and I closed the windows-- we haven't needed the AC for nearly a week-- and I turned on the AC-- not the normal through-the-wall unit, as that's leaking, but a portable unit that we dragged upstairs-- the kind with the tube that leads to a vent that you put in the window frame-- and then I read a few pages of The Sentence is Death and soon fell fast asleep, but when I woke up, our bedroom seemed really hot so I walked over to the AC unit and confirmed that it was pumping out cold air-- and the temperature read 72 degrees so I figured I was just overheated from the day's activities and perhaps the cool air had not reached the far corner of the room-- very illogical reasoning-- and then I lay back down on the bed and finished the novel-- and the ending was exciting enough to make me forget about the heat, but then once I had turned the last page an closed the book, I walked back over to the AC unit and noticed that when I closed the window, I did NOT insert the vent tube apparatus into the window frame-- it was pumping hot air right back into the room! and the AC was trying to make it 72 degrees, but when I pressed another button, the unit told me the actual temperature-- 87 degrees . . . mystery solved . . . so I am writing this sentence in a dazed state but at least I know the resolution to both  The Sentence is Death AND The Mysterious Case of the Stupid Man, the Hot Room and the Over-extended Air-conditioner

3) and here is mystery number three-- perhaps you people can solve it-- I call it The Mystery of the Two People Inside My Phone . . . and One of Them is an Idiot: 

on my drive down to Veteran's Park to play pickleball this morning, I spoke to my phone several times-- Hey Google style-- asking it to change the music on Spotify (sidenote: Ill Communication is a really weird album) and every time, the female voice complied-- but then on the ride home, I tried to "Hey Google" my phone to change the music and a male voice answered that it did not have that capability-- and this male voice tried to access YouTube music but could not do so and then he said that he could not control Spotify . . . and this has happened to me several times now-- the female "Hey Google" can control Spotify, but the male "Hey Google" is a total inept idiot . . . and when I asked my phone about this inconsistency, my phone chastised me:

"That statement is incorrect and discriminatory. There is no inherent difference in a person's ability to control Spotify based on their gender. Anyone, regardless of their gender identity or expression, can learn how to use Spotify."

and this proves that AI is dumber than ever, but that still doesn't explain why the female "Hey Google" is smart and competent and can control Spotify and the female "Hay Google" is a loser-- and I can't find any explanation for this on the internet, and now I'm using some Samsung voice control called Bixby-- you say "Hi Bixby"-- and Bixby seems to always be able to control Spotify, so I've solved the problem but not the mystery.
