    Ah I see the concern there. Fingerprint data isn’t handled as much on the software side as it is through the hardware. Android doesn’t get access to what’s actually scanned, just whether a scan was read and if it matched what the reader was expecting, Scanners are limited to a certain number of entries depending on how much space is available to store fingerprint data, which is why my 256gb phone can only store 4 fingers. It’s also why you can’t add separate fingers in separate apps, they all use android’s API to determine whether a biometric scan was a success or not.

      Really? Really?

      My phone only has 64GB storage, and it allows 5 fingerprints. Hell, I just added one of my toes as a test to confirm.

      You got a device with 256GB, and they subtracted a fingerprint? What the fuck?

      New devices will remove features, and you’ll fucking like it…

        Tradeoff between speed & accuracy vs the amount of fingerprints. The data that would’ve been required to store a 5th is instead used to have better models of the other 4. Id rather have a faster reader that’ll read it right in more angles than an extra fingerprint when I only really use my thumb and index anyway. (Also you can totally train 2 different fingers in one “finger” and it’ll recognize both, just worse

          It literally took me less than 0.1 seconds to unlock my 7 year old phone with my toe.

          How impatient are you? FFS, the technology has been out there and pretty well refined for decades.
