First of all, the pictures taken with Samsung flagships are not fake.
The algorithm Samsung uses to enhance these shots is a bit of a stretch to be considered AI. It's more like a photo mode, similar to Food Mode or Portrait Mode, rather than true AI-driven processing in the sense it's referred to here on this thread when people talk about AI.
To clarify this further, here's a screen recording where I took photos of the moon using an S23 Ultra. I used Gcam, which is a fork of the Pixel camera app, wasn't developed for Samsung phones so it also doesn’t have any Moon enhancement algorithms or special features like those found in Samsung’s native camera app.
This more than proves the capabilities of the hardware. Samsung doesn't need to "fake" Moon pictures, it only makes them look a little better through processing (so something all smartphone manufacturers do)
Now second, it would be really interesting to know what AI features "Android users" showed you and what would you categorize as impressive?
For example, this summer while I was on vacation I really had to speak with somebody that can only speak Portuguese, so I uses the Interpreter feature found on Samsung phones. The person was blown away by the fact that we could communicate with no effort in real time while not knowing each other's language, and also without an internet connection.
Also Circle to Search is God send, even if it's more Machine Learning than anything else but also other stuff like Natural Language Processing and AR etc. it's usefulness is incredible, the best Android feature in the last few years.
