Latest questions about "contacts information"

How long do contacts stay in the 'Recents' section on your Snapchat for without you snapchatting them?

I had a system lock on power up and now I want to access my contacts in the old handset, but now it tells me I have an incorrect lock code.

I did everything you told, but instead of appearing the contacts the following code type appears: =pref. What is this? How can I see the contacts?

When I make a backup from the principal identity (including contacts and parameters and rules), I disconnect my Transcend 320GB and lose all contacts and parameters.
