using op9 for 3 days already.
negatives:
the fingerprint reader is too close to the home button. I've accidentally exit the app too many times when I want to authenticate with fingerprint.
also in one game, there is some touch screen lag
positives:
software - oneplus users will know how good oneplus software is. the little things they do to enhance user experience. in this version, i really like the dual-sim shortcut and work mode feature.
camera - i compare with my wife s21 and honestly i cannot tell the difference. OIS or non-OIS. quality of pictures is the same. oneplus edge out in ultra-wide, s21 edge out in selfie.
battery - i got 8 hrs screen on time, which is enough for one day usage. charging is fantastic, the same charger can be use for laptop as well.
