I recently see a report where s9 checks blood pressure or after that they check blood pressure on a B.P Monitor or the results are very good they almost same .
Very good features by Samsung.
S9 or S9 Plus Camera
I seen lot of videos on youtube of s9 or s9 plus camera comparison but not everytime galaxy s9 camera done a good job . Also the Super slow motion video quality is not good .
Probably s9 plus but need better battery life or better camera or good specs.
Or big rumor of note 9 is a under display fingerprint scanner. That is a game changer.
But I buy s9 plus .
