I have recently updated from Android 8.1 to 9.

Since the update, there's a problem that keeps popping up every now and then. no matter how often I type the password, it does not get accepted. And I'm sure the password is right.

The only way out is to re-boot the phone. Then my password will be recognized again, until after a couple of days the problems arises again.

My phone is a Nokia 1, Build number 00WW_2_130_SP01.


  • tried changing the password, didn't work.
  • tried changing PIN for keyboard password input, didn't work
  • noticed that the previous login before this happens, I input the right password, the device lets me in, but shows the message "Wrong password". And in the next lock, it's for real, it won't recognize the right password.
  • Have you tried a factory reset? If it does not work correctly after a factory reset I would assume that this is just ab bug of the current version.
