Xperia is in my opinion the only phone left worth buying. It has all the bells and whistles you expect from a flagship phone + a headphone jack, SD card slot and very good camera.
I love being able to manually do what ever I want in the camera app and having the camera button is just nice.
Had the Xperia Z3 back in the day after my beloved Sony Ericson Xperia Play died. Loved both phones. Switched to Samsung for a few years and are now back to Sony (Xperia 1 IV) since 2023. Words can't describe how happy I am being back. :D
Yeah, the Sony phones do that as well. The special part of the camera button is that it acts like one on a proper camera. If you half press it (you can feel a slight change in resistance when you hit the spot) it engages the focus and then you can press it fully to take the picture.
I was able to program the Bixby button on my Samsung S10+ to take pictures as well, but it lacks the half press feature.
