Hello!:
The problem has come with the last update, minor bugs ..
But it has erased the factory application "notes" with all the notes and the next tasks and appointments throughout the year.
I would also like to highlight that with the last update, sometimes if, sometimes not, the fingerprint sensor unlocks the screen. other times he does not recognize that he has a sensor and he directly asks me for code.
We have a solution for these things?

PS: until yesterday, before the update, I was really happy with the work you do with this phone.

Thank you very much for your attention

Hi there! After each firmware update you should perform a factory reset to avoid weird issues like these. Please perform a factory reset
