The report is saying that Samsung Display has come up with 3-4 solutions with regards to an in-display fingerprint sensor, and that the company is expected to make a decision soon on what they will go with. It is possible that Samsung might not go with any of the solutions and keep to the rear-mounted sensor which is what some are saying, or Samsung could pick one of the solutions and go with it.
It also seems that due to Samsung having yet to make a decision that as a result, the Note 9’s design has yet to be finalized due to fact that the design will be dependent on what Samsung decides on the fingerprint feature. That being said, Samsung did previously hint that they would release the feature when they believe that it works 100% of the time.
This led to some speculation that maybe it might not arrive in time for the Note 9, but this latest report seems to suggest that it might. Either way it’s probably best taken with a grain of salt for now since we’ll probably have to wait quite a bit before we see it.
