I've configured Mail for Exchange on my Nokia N9. This makes password lock for the phone mandatory for security reasons.
I find the following problems after the configuration was done
1) The screen now hangs when a calendar reminder/call comes in.
2) Sometimes; when unlocking the phone; the password is never asked for. It goes straight in.
3) The password when being typed is displayed for a few micro-seconds; long enough for any trespasser to note it down. This happens however fast I type in the password.
Please let me know if there are any solutions for these issues.
