My opinion about this phone.
As u know phone is good in hand lets talk about its cons only
No improvement in camera from s7 to s8. except the dual pixel technology which helps in focusing very fast thats it.
Fingerprint position.i dont why Samsung do this. position is very awkward as u use this phone for the first time.your hand is always touch the camera not the scanner
Average sound
Bixby not good as Google assistant
Small Capacity of battery.
Price is bit High as my opinion
Any queries and help.dont hassitate to ask in comment section below
