photonmammoth, Nov 8, 2018 : For some reason my 6t can't ever seem to properly get my 2nd thumb memorized and function with it properly. My right thumb is always fine, but my left only works 5% of the time. I've tried re inputting the print several times too. One thing I noticed is immediately after doing that it is much more quick to respond and to recognizes the fingerprint almost instantly, but as the day goes by it seems to almost forget it exists? Any ideas?
