Never had problems with them. My new air fryer uses them so I use them several times a week to make easy prep meals or common freezer items like pizza rolls or whatever. Boarding passes have never been a problem either, though I don't usually fly because it's a pain in the ass.
Not sure if the screens are OLED but a lot of people sleep on Xperia phones and the flagships are pretty nice. I've used them for years and only switched to a Pixel 8 because it was on sale for $350 and included a year of unlimited service.
Xperia Z compacts were awesome because of this.
