Last updated on: June 12, 2021

migrate to Galaxy S21 with Samsung Smart SwitchYou can use Samsung Smart Switch to migrate to Galaxy S21 from other Android phones or an iPhone easily. Most of your data can be easily copied to Galaxy S21.

This Galaxy S21 guide shows you how to use Smart Switch to migrate to Galaxy S21 wirelessly (WiFi Direct), explains what data can be migrated, gives suggestions or solution on how to migrate data that cannot be migrated to Galaxy S21 directly.

Please note, Smart Switch works identically on Galaxy S21, S21+, and S21 Ultra. So, this guide applies to all these 3 models of Galaxy S21 although we use Galaxy S21 in the text.

Why should you use Samsung Smart Switch to migrate to Galaxy S21?

But if you were using non-Google services/apps, then a lot of data will not be backed up to Google Cloud. For example, if you use the Samsung messages app, then your SMS will not be backed up to your Google account.

Besides, none of the phone settings is backed up to your Google account.
