Why are some contacts missing in some views after an android update followed by restoring the contacts?
Go into your contacts Tab.

Press Menu > Display Options

You can then select 'Display only contacts with phones'

Also There is a list of accounts with 'Choose contacts to display' above it.

If you select each one of these you can choose which groups to hide or show, this may be were the numbers are being hidden.



Also within your text messaging app, you can press:

Menu > Settings and there is a setting that says 'Only mobile numbers'

deselect this as sometimes it hides numbers thinking they're not phone numbers when they are!
