I never got on the Xperia train cause my buddy had a rough experience with one (long before I went to the dark side and bought an iPhone).
But I did think the camera stuff seemed cool.
One of the few things I truly miss going from my OnePlus 7T Pro 5G McLaren Edition (greatest phone I ever owned, may it rest bricked in peace) to the iPhone is being able to open the camera without waking the phone first. Double tapping the power button to open the camera was great. On iPhone I have to wake the screen and then get to the camera, which is fast but not NEARLY as fast, so I sometimes miss shots I would’ve gotten with an Android phone. This should also fix that (as did the Action button in the iPhone 15, I think, but I don’t have that).
