I think OP's point was more that the girl he dated wasn't going to get with HIM for the night because HE had an iPhone (and not an Android, like her). The bias was coming from OP's date, not OP.
Maybe...
But, that sounds as if the OP had more of a problem with her and not the type of phone she was using, which I can totally understand.
If it was just that and the problem with with her and not the OS that one uses, what I don't get is the comment about filtering the OS one uses in dating apps:
Think dating apps need an android/iOS checkbox.
Sounds like OS did play a part in the OP's dating preferences, especially since the OP noted other things that annoy him about people's phones (contrasting background).
BTW, I am not knocking the OP for their preferences what is important when it comes to a potential mate, everyone is different. I am just saying a brand of phone wouldn't deter me. The condition of the phone wouldn't deter me that much either, at least to a point.
Yeah that. Also her phone was disgusting ?
This kind of reminds me of my wife a while back, before we were married. She is a psychotherapist, and when she was early in her career, she did in-home counseling to low-income clients. (pretty much the norm for her career)
Some were people that just fallen on hard times, and needed help getting back on their feet. Most were multi-generational dependents of the government, with no motivation or incentive to get back on their feet.
My wife would tell me that almost every client that fit the latter group would never have their electric bills and rent paid, but would alway have money for smokes, the newest iPhone, and an expensive TV.
My wife on the other hand was using an iPhone 5, with a cracked screen. I put packing tape on the screen to prevent her fingers from getting cut.
She, like most people in her career, didn't make much money. Being a social worker is more of a calling than something to make a living, especially since there is so much educational and certification requirements. So, she said she would keep using her cracked iPhone until it fully broke.
She would get comments from her clients, stuff about the cracked screen and them suggesting her get a new iPhone. This kind of annoyed her.
I ended up giving her my 5s when the 6s Plus came out, which she cracked as well. I then got her a SE1 when they launched, and a Otterbox Defender case. She has yet to crack that one, and I a few weeks ago, I got she the SE3 with the same case to replace her again SE1.
The point is, brand and condition isn't exactly the best indicator of the type of person, imo.
