The OnePlus Switch is now called the Clone Phone. With this app, you can easily transfer your contacts, messages, photos, and other data from your previous phone to other OnePlus phones.

◆ Data migration
With Clone Phone, you can easily transfer your data from Android devices to OnePlus phones without a network connection.
(Transfers from iOS devices may require a data connection.)
What you can transfer: contacts, SMS, call history, calendar, photos, videos, audio, apps (including data of some apps).

◆ Data backup
The data backup function enables you to backup your data safely for restoration when needed.
What you can backup: contacts, SMS, call history, notes, desktop layouts, apps (excluding data).

Note:
1. Supported data may be different in different systems and Android versions. Please check if the data is still available after a transfer or a backup restore.
2. If the app crashes, gets stuck, fails to open, or encounters any other issues, please give us feedback or a bug report on the OnePlus Community forums.
3. If Clone Phone informs you of insufficient storage space, you can try to transfer data in batches or clear the device’s storage space.
