Yep, that's the same version as mine. Post update mine is 'amazingly good' to be honest, I have found myself using the fingerprint instead of the face often, as it's that quick/reliable.
Not sure if it's any use, I have 'Touch Sensitivity' OFF in settings (Display section) and I have no screen protector fitted.
as a benchmark, I just unlocked it 10 times in a row with my thumbprint to check success rate.. 10/10! There is NO WAY that would have worked before the update (more like 2/10! on a luck day!).
