My Xperia z3 doesn't have the feature "my xperia" or "tap and pay" they have told me i need to go to update center then applications but when i try that it doesn't sh0w. i haven't receive any notification on it. Its not under security either. So does it need a restart or reset???
The best thing that you could do to check if any of these features should be available for your device, would be to contact your local support:

For example, the availability of the my Xperia service depends on operator, product and country.
Was the phone bought here in the US?
