I used Find My Device to set a 20-character password for my phone (it accepted the password without any error messages as shown in the picture below). After I got my phone back, I went to type in the password on the lock screen, but I could only type in 16 characters.
I saw on Password too long to type in android device.Locked out from android device manager that mentioned the lock screen would accept the truncated password, but my phone does not unlock with the truncated, 16-character password.
I don't want to resort to a data erase, since I have important texts and memos, and also some contacts I don't want to lose. Is there any solution to this?
