Some iPhone Duo users are testing a Touch ID workaround shared on Reddit: instead of registering the pad of the index fingertip, they register the lowest part of their index finger. According to the original poster and subsequent forum reports, the lower finger segment rests more naturally during pickup and can be used to unlock the phone as it is lifted.
MacRumors frames the tip as potentially “arguably better than Face ID,” while noting that results may depend on individual grip styles and that the method is not guaranteed for everyone. The outlet also points readers to the Settings path where additional fingerprint areas can be registered, encouraging users to try the approach themselves.
Daring Fireball highlights the same core idea and emphasizes that the poster demonstrates the motion in a video and says it helps with quickly checking notifications from the lock screen. Overall coverage centers on practicality—how easily the finger contacts the sensor during use—rather than any official guidance or testing beyond user reports.
