You can often transfer data to a new Android phone after setup without factory-resetting it. Start by looking for Finish setting up in Settings or in your notifications. If that option is gone, open Settings, then look for Accounts & backup and an option to copy data from another device. Google says this post-setup option is available on all devices running Android 17 or later and on selected devices with earlier versions. Pixel 9 and later phones have Android Switch for post-setup transfers, while Samsung Galaxy phones and tablets can use Smart Switch after setup.
A post-setup transfer normally adds selected information to the new phone; it does not turn the phone into an exact copy of the old one. Back up anything already created on the new phone, transfer only the categories that are missing where possible, and keep the old phone until you have checked the result.
Choose the right transfer route before resetting
- Check whether setup is unfinished. Open Settings and look near the top for Finish setting up. You can also pull down the notification shade and look for Finish setting up your device. This is the best route when you skipped migration only recently.
- Look for the Android post-setup copy option. In Settings, open Accounts & backup and select the option to copy data from another device. Names and locations vary between manufacturers. Follow Google’s current guidance for transferring data after Android setup if you cannot find the command.
- Use the phone maker’s migration tool when available. On a Pixel 9 or later, search Settings for Android Switch or Copy data. On a Samsung Galaxy device, search Settings for Smart Switch.
- Use a direct transfer when the old phone still works. This is usually the strongest option for local photos, message history, call history and files that were never backed up to an account.
- Use account sync or a cloud backup when the old phone is unavailable. Sign in to the same Google Account and other relevant accounts. Contacts, calendars and Google Photos content may reappear through syncing. A Pixel 9 or later can also offer an eligible cloud backup through Android Switch.
- Reset only when a needed route is unavailable. A reset may be necessary for a full setup-only restoration, but it should be the fallback after you have protected the content already created on the new phone.
Hypothetical situation one: You skipped migration, installed apps and took new photos on the new phone. Back up the new photos first, then use the post-setup transfer tool to select only the missing messages, media or files. Resetting the phone is unnecessary if the required categories can be copied after setup.
Hypothetical situation two: Your first transfer brought across contacts and apps but stopped before messages and photos were complete. Reopen the same transfer tool, reconnect the old phone and choose the missing categories. Avoid automatically selecting everything again unless you need to, because a broad second transfer can create duplicates.
Prepare both phones and protect new content
- Update both devices. Install available Android, Google Play system and migration-app updates. Restart both phones before beginning if either has just updated.
- Charge the phones. A cable transfer can occupy the charging port. For a large wireless transfer, leave both phones connected to power.
- Check available storage. On the new phone, open Settings and search for Storage. Make sure there is room for the categories you intend to copy, plus space for apps and temporary transfer files.
- Keep the same source phone available. If you already copied data during initial setup, Android can require any additional post-setup transfer to come from that same device. A Pixel 9 or later can restore from only one previous device unless the Pixel is reset.
- Know the old phone’s screen lock. You may need its personal identification number, pattern or password to unlock it and authorize the transfer.
- Use a data-capable cable. Some Universal Serial Bus cables provide charging only. If the devices do not detect each other, try another cable or a compatible adapter.
- Remove connection obstacles. Keep Wi-Fi enabled. If pairing fails, temporarily turn off a virtual private network and stop the old phone from automatically joining a different Wi-Fi network.
- Check management restrictions. A business- or school-managed device may block transfers or exclude work-profile content. Ask the organization’s administrator what can be moved instead of trying to bypass its controls.
Back up what is already on the new phone
Before adding data, open Settings and search for Backup to confirm that device backup is enabled where your phone supports it. Check that Google Photos has finished backing up any new pictures and videos. Make separate copies of irreplaceable Downloads, Documents, recordings and other local folders to a computer, cloud drive or external storage device.
Open any app where you have created notes, drawings, recordings or documents and use that app’s own sync or export feature. A device migration tool cannot reliably merge every app’s private database. Authentication apps need special handling: use the dedicated process for moving Google Authenticator codes or transferring Microsoft Authenticator safely before erasing either phone.
Copy data through Android Settings
On Android 17 and supported earlier versions, try the system transfer option before assuming that migration was available only during first-time setup.
- Unlock both phones and connect them to Wi-Fi. Connect a data cable as well if the prompts recommend a wired transfer.
- On the new phone, open Settings.
- Tap Accounts & backup, then choose the option to copy data from another device. If the label is absent, search Settings for copy data, transfer data, Android Switch or set up device.
- Follow the instructions to connect the old phone. Depending on the devices, this can involve scanning a quick-response code, confirming matching codes or connecting a cable.
- Review the available categories. After a partial transfer, select only missing items such as messages, photos, videos, files or apps.
- Keep both phones unlocked, nearby and connected until the new phone confirms that copying has finished.
If Finish setting up still appears, it may return you to the unfinished setup flow. This option is manufacturer-dependent and can disappear after a limited period. When the old phone contains unsynced local data, a direct transfer is generally preferable. When it is lost, damaged or inaccessible, cloud restoration and account syncing can restore only information that was backed up or synchronized earlier.
Use Android Switch on Pixel or Smart Switch on Galaxy
Pixel 9 and later
Pixel 9 and later phones can add data after setup with Android Switch. The usual path is Settings > Accounts & backup > Android Switch > Start. Some Pixel software versions instead show Settings > Back up or copy data > Copy data. Scan the code with the old phone when asked, choose the needed data and tap Copy.
If the old phone is unavailable, select Can’t use other device? when that choice appears and choose an available cloud backup. A Pixel can attempt to merge additional content with data already on the phone, but duplicates remain possible. If you need to restore from a different previous device after one has already been chosen, Google requires a factory reset first.
Earlier Pixel models may show a temporary Finish setting up your Pixel prompt, but they do not have the same general Pixel 9-and-later post-setup Android Switch support. If no system transfer option appears, sync accounts and copy files individually before deciding whether a reset is worth the disruption.
Samsung Galaxy phones and tablets
On the new Galaxy, open Settings, search for Smart Switch and choose Receive on this phone. On the old Android device, open or install Smart Switch, choose Send from this phone, then select cable or wireless transfer. Samsung’s Smart Switch transfer instructions confirm that you can choose Everything, an accounts-calls-contacts-and-messages group, or Custom after the scan.
A cable can transfer more data types, but wireless transfer lets both phones stay on their chargers. Smart Switch can be used after setup without deleting the Galaxy’s existing content. Samsung’s separate Quick Setup method, which uses a quick-response code to bring over accounts and network information during the initial setup wizard, does require a factory reset if you want to use that particular route later.
Know what transfers and what needs separate work
| Content | Usual route | Important limitation |
|---|---|---|
| Contacts and calendars | Account sync or direct copy | Contacts and calendars already synced to Google usually return after you add the same Google Account. Other account services may require their own sign-in. |
| Photos and videos | Direct copy, Google Photos or manual file transfer | Media in hidden or locked folders may be excluded. Cloud-only media must be available from the relevant cloud account. |
| Messages and call history | Migration tool or Smart Switch | Large message libraries can take time to index after copying. Search for known messages before treating them as missing. |
| Apps and app data | Reinstall from an app store or restore through backup | An app may return without its login, downloads, saved game or private data. Some apps deliberately exclude sensitive information. |
| Downloads and documents | Manual cable, cloud-drive or file-manager copy | Downloads, including Portable Document Format files, are not reliably included in every Android transfer. |
| Authenticators, banking and secure apps | Each app’s transfer or recovery process | Security-sensitive data is often excluded and may require identity checks or a new sign-in. |
| eSIM | Carrier or supported device-transfer process | Copying device data does not guarantee that a cellular plan moves. Use the carrier’s instructions or the correct process for transferring an eSIM between iPhone and Android. |
Use the old phone’s Files app to inspect Downloads, Documents, Movies, Music, Recordings and app-specific folders. Also check hidden gallery folders, Secure Folder on a Galaxy device and any memory card. Copy items separately when they are not listed by the migration tool.
Resolve transfer failures and missing content
- The post-setup command is missing: Search Settings with several terms, check notifications for unfinished setup and open the manufacturer’s transfer app. If Android 17’s option and any manufacturer alternative are unavailable, copy individual categories manually before considering a reset.
- The new phone lacks storage: Back up photos and videos to Google Photos, then omit them from the direct transfer if they will sync to the new phone. Remove offline media or unused apps, or move smaller categories first.
- The transfer stalls: If it remains stuck for at least 15 minutes and a stop option is available, stop it, restart both phones and retry. Use fewer categories, replace the cable or switch between wireless and wired transfer.
- Data appears twice: Allow syncing and message indexing to finish before deleting anything. Compare dates, file names, contact details and message threads, then remove only confirmed duplicates. On a Pixel, clearing the affected data set and repeating that category can be an option when Android Switch cannot merge it.
- An app returned without its records: Sign in and check the app’s own backup or export settings. Apps that do not use Android backup, apps installed outside Google Play and protected private data may need a developer-specific process or may not be transferable.
- WhatsApp is already set up on the new phone: Do not assume two separately created chat histories will merge. Preserve any new conversations you need. For a post-setup device transfer, Google advises uninstalling and reinstalling WhatsApp, or clearing its storage, before transferring if it was already opened or configured on the destination phone.
- Work data is absent: Personal migration tools can exclude managed apps and work-profile files. Enrol the new phone through the employer or school so its management system can restore permitted work content.
Verify the new phone before erasing the old one
Keep the old phone intact for several days when possible. A completed progress bar means the transfer process ended; it does not prove that every important item arrived. Check the following before you erase or trade in the old device:
- Search for several old text messages, including messages with photos or other attachments.
- Compare approximate contact totals and open contacts with multiple phone numbers or email addresses.
- Check the oldest and newest photos, videos, screenshots and albums.
- Open important downloads, documents, recordings and offline music.
- Confirm calendar events appear under the correct accounts.
- Launch essential apps and verify logins, records and offline data.
- Test authentication codes, banking access and password-manager access.
- Make and receive a call, send a text and confirm that the SIM or eSIM is active.
- Open WhatsApp and other messaging apps to check the expected history.
- Review any transfer summary for skipped or failed categories.
If only a few files are absent, copy them manually instead of repeating a full migration. If an essential setup-only category cannot be restored and a reset becomes necessary, first complete a fresh backup of the new phone, export app-specific data and make separate copies of new photos, downloads and documents. Erase the old phone only after the new one has passed the checks that matter to you and your backups can be opened successfully.
