How to Transfer Data to a New Android Phone Safely

Moving to a new Android phone? Here's how to transfer contacts, photos, apps, and WhatsApp chats safely, without losing anything in the process.

9/9/20265 min read

A new phone is exciting right up until you remember everything sitting on the old one. Years of photos, group chats, saved passwords, game progress — losing any of it during the switch is the real worry, not the setup screens themselves.

This guide walks through the safest way to move your data across, based on what phone you're switching from and to, plus what to check before you wipe the old device for good.

Before You Start: A Quick Safety Checklist

A few minutes of prep avoids most transfer problems.

Charge both phones above 50%. Transfers can run anywhere from 20 minutes to a couple of hours, and a phone dying midway can leave the process half-finished.
Update your most important apps — messaging, banking, and authenticator apps — before you start.
Write down backup codes for any two-factor authentication apps. Not all of them transfer automatically.
Connect to a stable Wi-Fi network rather than mobile data. Moving several gigabytes of photos can burn through a limited data package fast.
Don't factory reset the old phone until you've confirmed everything has actually arrived on the new one.

The Built-In Way: Android's Setup Transfer

Worth flagging: Google recently changed what counts against the free storage that comes with a Google account. New accounts now start with 5GB rather than 15GB unless a phone number is verified, and since mid-2026 the SMS, call history, and settings portion of an Android backup counts toward that quota too (the average increase is small, around 40MB). It's a staged rollout, so check your storage under Google Account settings before relying on cloud backup for a large transfer.

Moving to a New Samsung Galaxy? Use Smart Switch Instead

If both the old and new phone are Samsung devices, Smart Switch handles brand-specific extras — like Secure Folder content and home screen layouts — that Google's built-in tool doesn't cover. It comes preinstalled on Galaxy phones, usually under Settings > Accounts and backup (or Cloud and accounts on older versions).

Wireless transfer:

Open Smart Switch on both phones.
On the old phone, tap Send from this phone; on the new phone, tap Receive on this phone.
Choose Wireless, then scan the QR code the new phone displays using the old phone's camera.
Select what you want to transfer, tap Transfer, and wait for it to complete.

A cable connection is slower to set up but noticeably faster for large libraries, and it's the option Samsung recommends if you have a lot of data to move.

Coming From an iPhone?

Google's Android Switch app (previously called Switch to Android) handles the move from iOS. It transfers contacts, calendar events, photos, and videos over Wi-Fi. Music, notes, and text messages need a cable connection instead, since they can't move over Wi-Fi.

Before starting, deregister iMessage on the iPhone so texts from iPhone users still reach your new Android number. WhatsApp chats aren't included in this process — they need their own transfer step, covered below.

Don't Forget WhatsApp — It Transfers Separately

WhatsApp chats live outside your phone's normal backup system, so they need their own transfer regardless of which method you used above.

Same-phone QR transfer (Android to Android, fastest option):

On the new phone, open WhatsApp, verify your number, and choose Transfer from old phone under Restore or transfer chats.
On the old phone, open the camera and scan the QR code shown on the new phone.
Tap Accept on the new phone and keep both phones unlocked until the transfer finishes.

Restore from a cloud backup:

On the old phone, go to Settings > Chats > Chat backup and back up to Google Drive.
Install WhatsApp on the new phone, verify the same number, and choose Restore from backup when prompted.

Either method replaces any chat history already on the new phone, and payment history and call logs don't carry over either way.

How to Wipe Your Old Phone Safely

Only do this once you're confident everything you need is on the new phone.

Open a few photos, contacts, and apps on the new phone to confirm the transfer actually worked.
Sign out of your Google Account and remove the old device from Find My Device (or Find My Mobile on Samsung).
Remove the SIM card, or deactivate the eSIM if that's what the phone uses.
Factory reset the old phone: Settings > System > Reset options > Erase all data. On Samsung phones, this sits under Settings > General management > Reset.
If you're selling or donating the phone, most devices running Android 10 or later are encrypted by default, so a factory reset is enough to make the data unrecoverable.

A factory reset erases everything and can't be undone, so skip step 4 until you've genuinely confirmed the transfer.

If the Transfer Gets Stuck or Fails

Work through these roughly in order.

Restart both phones and try again on the same Wi-Fi network.
Move the phones closer together and turn off battery saver, which can interrupt background transfers.
Switch from a wireless connection to a cable — it's more reliable and covers more data types.
If the new phone ends up in a half-finished state, restore from a Google One backup instead of continuing the stuck transfer.
As a last resort, factory reset the new phone to restart the guided setup transfer from scratch.

Frequently Asked Questions

Do I need Wi-Fi to transfer data to a new Android phone?

For the wireless method, yes. A cable connection works without Wi-Fi, but you'll still need it briefly to sign in and download apps.

Can I run the built-in transfer after I've already set up my new phone?

Usually not without a factory reset. Pixel 9 series phones are the exception, since Google lets you reopen the Android Switch tool later.

Will switching phones delete anything from my old device?

No. The transfer only copies data — nothing is removed from the old phone until you factory reset it yourself.

How do I move WhatsApp chats separately from the rest of my data?

Use WhatsApp's own transfer option: the QR code method between two Android phones, or restoring from a Google Drive backup during setup.

What if my old and new phones are different brands?

Google's built-in transfer works across brands because it's part of core Android. Manufacturer tools like Smart Switch add extra features but aren't required for a cross-brand move.

Bright living room with modern inventory

Every Android phone with Google Play Services includes a guided transfer as part of initial setup. It's the method Google itself recommends, and it works between different brands because it's built into core Android rather than tied to one manufacturer.

Power on the new phone and tap Start on the welcome screen.
Connect to Wi-Fi when prompted.
Choose to copy apps and data from your old device.
Pick a cable connection (faster, and better for large photo or video libraries) or a wireless connection, then follow the on-screen pairing steps.
Sign in with the Google account you used on your old phone.
Select what to bring over — apps, contacts, messages, photos, and settings — and wait for the transfer to finish.

This one-time transfer generally can't be repeated once you've finished setting up the phone, so it's worth doing before you start customizing anything. Pixel 9, Pixel 9 Pro, and Pixel 9 Pro Fold owners are the exception: Google lets you reopen the same tool, called Android Switch, from Settings or the Play Store after setup. Most other Android phones don't offer that option yet.
