Lost all contacts after upgrade.

[Straner]

After Z5 Premium Dual update i lost all my local contacts.  

All filters are enabled.

Is there any way to get them back?

If you have done any older backups, then try to restore your contacts from them. Otherwise it would not be possible to get them back.

I hope I don't sound like a dork but... all my contacts are associated to my gmail account that I log into Android with... then you never ever lose them.
