Yesterday I have lost all the contact on my GT -I9000. The device was kept ideal for 5 min & when I chwecked it again for some work , I have found that the contact Nos has been lost & I am not able to trace them. Is this teh common problem with GT-I9000 ? Is there any method to get the lost contacts again?
I don't know how you lost them or if its a common problem. But you definitely can get back the lost contacts provided they were synced with Google Contacts(not SIM contacts).
First try to sync and see if contacts come back. If we cleared data of "Contact Storage" from Manage Applications, all the synced contacts in phone will disappear until you sync back again.
If that doesn't help, Google Contacts fortunately has restore option. Open Gmail, go to Contacts, Select More and select Restore contacts.
