Only two problems I have noted with V23 firmware:
1) The fingerprint sensor doesn't allow me to unlock my Cosmo with the screen closed. I have to type in my PIN on the CODI instead. it is as if the sensor has gone to sleep, as there is no response. If the screen is open, the unlock with fingerprint works every time.
2) With my screen open, if I type the wrong PIN on the physical keyboard, then the keyboard won't register any presses and I am forced to use the on-screen keypad instead.
Anybody else got these issues?
