How do I export my Samsung Galaxy 551 contacts to my Samsung Galaxy S2? How do I export my Samsung Galaxy 551 contacts to my Samsung Galaxy S2?
If you want to do it without going via Google, just follow these steps. To make it easier for others to follow, I refer to your Samsung Galaxy 551 as "old phone", and the Samsung Galaxy S2 as "new phone":


On the old phone:

Open the Contacts app
Tap the "menu" button to bring up its extra menu
Select "Export/Import", and chose to export your contacts to SDCard
Pick the created file (it's most likely named 0001.vcf, or at least similar – .vcf stands for "VCard File") and copy it to your PC

On the new phone:

Copy the 0001.vcf from your PC to the SDCard
Follow steps 1-3 from above, but in step 3 this time chose to import the VCard File
Select the VCard file from your SDCard, and have it imported



You're done – all contacts from your "old phone" should now be on the "new phone". Additionally, you've got a backup on your PC which you can easily import to other PC applications as well: most contact handling applications should understand this format.
