Fingerprint. You need to lock and unlock the phone once, then fingerprint would start working.Great rom so far, I just clean flashed it coming from OOS11.
Though when I tried to set up fingerprint unlock it doesn't work, at all (not unlocking it, but first setting it up in the settings). I can tap as often as I want and it doesn't register anything, the fod doesn't light up either. If I press around the screen a bit it tells me to tap on the fingerprint sensor on the back, which obviously isn't the case for the OP9.
Looking for a new daily rom and everything else works so far, so a fix would be awesome.
