One gripe I would have to say it notifications. iOS does it much better in my opinion.
If I have my iPhone on also on WiFi while sitting at home, the iPhone will get notifications much faster.
Some notifications on my S23U won't even show up until I unlock the phone. For example my daily Bible quotes I get at 12pm. On the iPhone, immediately on the iPhone at noon I will hear the notification tone, and the Bible quote pops up right on the screen. On the S23U, I don't even hear a notification sound mostly for it, and sometimes, even though I don't hear it, I will see it on the lock screen. Other times it won't even show up at all until I unlock the phone.
GooglePay notifications are always delayed. My bank sends a push notification to your phone whenever any of my cards are used. On the iPhone they come up immediately, on the S23U, they are always delayed a minute or two.
Overall I am enjoying the phone, but there are a few things that iOS still does better.
Oh, one other bonus gripe.
I hate rolling rollouts for Google apps. For example, Android Auto 9.5 got released the other day. But with the crazy rollouts they have, I still haven't gotten it yet.
