Same here, I was really getting sick of re-training the damn thing every time the seasons changed. Drier air and colder? TouchID drops to maybe 10% success. Hum

Same here, I was really getting sick of re-training the damn thing every time the seasons changed. Drier air and colder? TouchID drops to maybe 10% success. Humid and warm again? Same. Took a shower or thoroughly washed your hands in the last 30 minutes? Or were swimming recently? TouchID doesn't work at all. Warmed your hands in front of a heater for a minute? TouchID's dead for a while. Ugh. Masks are a problem with FaceID, of course, but otherwise it's a huge improvement, in my experience. I gather some people didn't have the trouble I did with Touch ID, so maybe for them FaceID is worse.

That's quite strange. My understanding was that most fingerprint readers were constantly updating their image of the fingerprint. For example shortly after enrolling my finger or after doing some manual work that made my hands feel raw it was noticeably less accurate to recognized my finger on the Pixel 4a. However I could quickly lock+unlock my phone with different areas of my finger and then it worked reliably.
