When it comes to fluidity and speed mas maganda yung note 9 pro not to mention mas maganda build ng note 9 pro, bilhin mo lang yung m31 if gusto mo maganda na camera, maganda na screen, lupet na battery life, at kung gusto mo yung samsung one ui 2. Personally m31 pick ko, ganda kasi ng one ui 2. Pero take notice sa mediocre processor performance.
