The S8 now comes with equipped with extra security features, most notably its iris scanner and facial recognition. Unfortunately, the most reliable sensor is still the tried and true fingerprint scanner, as the newer sensors aren't fully reliable as of yet. The iris scanner has been found to have trouble reading eyes in bright light, while the facial recognition feature has been shown to be fooled by photos. As of now, we highly recommend using the fingerprint sensor as a primary way to unlock your phone until Samsung irons the kinks out with the other options.
However, the fingerprint scanner's location has been a point of contention for many, as its placement off-center beside the rear camera lens has many people feeling like it's hard to use. What you might not realize, though, is that it isn't so bad if you take a couple of tips into consideration.
First off, be sure to save your index fingerprints at least twice to have it read more reliably, whether you're right- or left-handed. Lefties will have an easier time locating the sensor, as their index fingers will more naturally place on the sensor. For right-handed people, though, it can be a little more of a challenge.
If you're right-handed, we recommend saving the fingerprint on your middle finger in addition to the index, as we found that it aligns with the sensor better. Using your middle finger also carries less risk of smearing or blocking the camera. A simple but effective tip is to use your index to feel for the rear camera's perimeter and use your middle to jump over the camera to access the sensor. It takes a little getting used to but is a great way to access the fingerprint scanner once it becomes second nature.
