KCYEOH, Jun 14, 2019 : Hi, i just got my OP7 pro 2 weeks back and i noticed there is some grease smudge at the left side of the front camera. I cleaned it then re-open the front camera and the smudge is back. I believe the grease might came from the track of the motorized camera. Although it didn't really cause any issue for now at the smudge doesn't really block the front camera lens, but i afraid it might cause problem in future. Does anyone having similar problem?
