This is just the perfect phone for me.
It comes with quite some beautiful design (Coral Blue)
Great screen, great camera for low light and slow mo, great performance (Exynos 9810) and 6GB RAM, great speakers, great biometric options, and the list goes on and on.
On the other hand, battery life is not as good as my previous phone (Galaxy A8 SM-A8000), and I hoped it is lighter and thinner like that phone.
Overall, this is just a special treat for me and I love it by my hearts.
P.S. I am glad I went for the Coral Blue S9+ UK 128GB Exynos variant, and it performs very, very well without breaking a sweat thermal wise (Snapdragon is known to heat up a lot more usually).
Also, since all the Snapdragon Samsung phones I had in the past had their motherboard toast after 2 years of usage or so, all my working Samsung phones are the more reliable Exynos (That A8 broke too with a broken display and unreliable battery, but mobo not toast yet) and I want to keep that trend of Exynos everything on my phones.
