. I had to angle my hand or arm in weird ways, and it’s easy to smear the camera - the software even warns you to be careful of the lens. Sometimes I got the S8 Plus unlocked on the first try. Other times I had to keep stabbing where I thought the sensor was, to get into the phone.
When this happens a couple times, no big deal. When it happens multiple times a day, for multiple days on end, it becomes frustrating and even a little obnoxious. Especially since there are so many fast, accurate fingerprint readers out there on other phones.
Compare that to the Pixel XL, which has a round target about a half inch lower than the S8 Plus’ oblong scanner, and the iPhone 7 Plus, whose fingerprint reader lives in the home button. ( The latest rumor is that the iPhone 8 may not even get one.)
