The answer is in your question itself. They look for a flagship to use the poco f1 is not a flagship. It has a flagship processor not an overall flagship experience, for one it's built from polycarbonate, it's camera isn't as good as flagships.
About the gif i can find you different gifs of iphone getting stuck. When i replied that time the gif wasnt playing so i guessed you were talking about the notch since that is the only downside anyone has found yet.
I'm not an apple hater what makes me dislike their products is fanboys like you. You can't seem to understand that apple is not as great as it used to be.
Ios used to be silky smooth to run and Android used to have bugs all the time, even the nexus phones but now you can just put yourself in the illusion that there is nothing wrong with an iphone. Do you yourself use a Xs and have checked yours. If not how about you actually search where all these bugs were reported.
I never said that iphones weren't good and i would only consider a flagship from either apple, google or oneplus because i can't get why someone would put their allegiance to q single brand as if their life depends on it.
