My previous phone was not Samsung. So I was facing problems to transfer my call logs, sms and phone book. I had to configure my new Samsung phone and transfer all the call logs, sms and phone book. At Samsung play store I found smart switch app. After reading its details, I downloaded smart switch on both of my phones. Then I started to transfer data using wifi. At the speed of 10MBPS the smart switch cloned my new phone. I had nothing to do then as I got all the apps with their settings, all the sms, call logs and phone book in my new phone. Although it took 45 minutes but my new phone was Same as my previous non Samsung phone. Thanks Samsung for proving Smart Switch.
