The fastest way to transfer everything is to sign into your Google Account on the new phone

When you turn on a new Android phone for the first time, it asks you to sign in with a Google Account. If you use the same account you had on your old phone, Android automatically restores your contacts, calendar, Gmail, photos in Google Photos, and most app data within a few minutes. You do not need a computer or any extra steps — just enter your password and wait.

This method works best if you have been backing up to Google automatically, which is the default setting on most Android phones. If you have never signed into Google on your old phone, or if you turned off backups, you will need to use a different method to move your data.

The transfer happens in the background while you set up the phone. You can start using it right away, though some apps and photos may take longer to appear if you have a lot of data.

Key Takeaways

  • Signing into the same Google Account on your new phone automatically restores contacts, email, calendar, photos, and most app data without any extra work.
  • If you did not back up to Google on your old phone, you can use a USB cable and Android's built-in file transfer tool to move photos, videos, and documents manually.
  • Some apps store data on their own servers instead of Google's, so you may need to sign into those apps separately on your new phone.
  • Samsung phones offer Samsung Smart Switch as an alternative that can transfer data over Wi-Fi or USB without needing a Google Account.

What gets restored when you sign into Google

Google Account backup covers most of what you use daily: your contact list, text message threads (if you use Google Messages), calendar events, Gmail inbox, Google Drive files, photos and videos in Google Photos, and the list of apps you had installed. When you sign in on the new phone, the system downloads all of this automatically.

App data varies by app. Gmail, Google Calendar, Google Contacts, and Google's own apps restore completely. Many third-party apps like Spotify, banking apps, and social media apps also store their data on their own servers, so signing into those apps on the new phone brings back your account and settings. Some older or smaller apps may not back up at all, which means you will need to set them up fresh.

Text messages sent through regular SMS or MMS do not back up to Google by default — only messages in Google Messages do. If you use a different texting app, check its settings to see if it offers backup. Photos and videos taken with your camera go to Google Photos if you have that turned on, but they do not back up if you turned off Google Photos backup on your old phone.

How to check if your old phone backed up to Google

Open Settings on your old Android phone. Tap Google, then Manage your Google Account, then the Data & Privacy tab. Scroll down to Data from apps and services and tap Google Photos. If you see recent photos there, backups are working.

You can also check by opening Settings, then System, then Backup (the exact path varies by phone brand). If you see a green checkmark next to "Back up to Google Account" and a recent backup date, you are set. If the backup date is old or missing, turn on backups now and wait a few minutes for the first backup to complete.

If backups were never turned on, you can still transfer data using a USB cable or Samsung Smart Switch, described below.

Using a USB cable to transfer files manually

If you only need to move photos, videos, or documents, you can connect your old phone to a computer with a USB cable, copy the files to the computer, then connect your new phone and copy them over. This method does not transfer contacts or app data, but it is reliable for media files.

Plug your old phone into a computer with a USB cable. On the phone, swipe down from the top and tap the USB notification. Select File Transfer or Transfer Files (the wording varies by manufacturer). On your computer, a folder window should open showing your phone's storage. Drag photos, videos, or documents to a folder on your computer.

Then unplug the old phone, plug in the new phone, and repeat the process in reverse — drag files from your computer to the new phone's storage. The files will appear in your Photos app or Files app depending on what you moved.

Samsung Smart Switch for Samsung-to-Samsung transfers

If both phones are Samsung, you can use Samsung Smart Switch, which transfers contacts, messages, call history, app data, and settings without needing a Google Account. Open Smart Switch on your new Samsung phone (it is pre-installed), tap Receive data, then choose Wireless or USB Cable.

For a wireless transfer, both phones must be on the same Wi-Fi network. Smart Switch shows a code on the new phone — enter it on the old phone, and the transfer starts. Depending on how much data you have, this can take 10 minutes to an hour.

For a USB cable transfer, connect the old phone to the new phone using a USB-C cable and an adapter (if needed). Smart Switch detects the connection and begins transferring automatically. This method is faster than wireless but requires the right cable.

Smart Switch also backs up to Samsung Cloud, so if you have a Samsung account, you can restore from a previous backup even if your old phone is not available.

What to do if apps do not restore their data

Some apps store data only on the phone itself, not in the cloud. When you install the app on your new phone, it starts fresh. To recover this data, sign into the app with your username and password — many apps will then read your account data from their servers.

For apps that do not have cloud backup, you may lose data. Banking apps, for example, usually do not back up transaction history, but your account itself is safe because it lives on the bank's servers. Games often do not back up progress unless you linked them to a Google Play Games account or a social media account.

Before switching phones, open apps you use frequently and look for a backup or export option in their settings. Some apps let you export data as a file, which you can then import on the new phone. This takes a few minutes but prevents losing information you care about.

Transferring data from an iPhone to Android

If you are switching from an iPhone, Google offers a tool called Switch to Android that moves contacts, calendar events, photos, and some app data. On your new Android phone during setup, tap Don't have an account?, then follow the prompts to sign in with your Apple ID. The phone will read what it can from your iCloud account.

This method does not transfer text messages or app data from iPhone-only apps. For text messages, you will need to use a third-party app or accept that they will not move over. Photos in iCloud can be downloaded to your computer and then moved to your new Android phone using the USB cable method described above.

Most of your important data — email, contacts, calendar — lives in accounts (Gmail, Outlook, Yahoo) rather than on the phone itself, so signing into those accounts on your new Android phone brings everything back automatically.

Frequently Asked Questions

Will my text messages transfer if I sign into Google?

Only if you use Google Messages as your default texting app. Regular SMS and MMS messages do not back up to Google. If you use a different texting app, check its settings for a backup option. Some apps like WhatsApp and Telegram back up to Google Drive or their own servers, so signing in brings your chat history back.

Do I need to keep my old phone turned on during the transfer?

No. If you are using Google Account backup, the new phone downloads data from Google's servers, not from your old phone. If you are using Samsung Smart Switch or a USB cable, you do need both phones connected, but they do not need to stay on after the transfer starts.

What if I forgot my Google password?

Go to google.com/accounts/recovery on a computer and follow the steps to reset it. You will need access to a recovery email or phone number you set up with your account. Once you reset the password, use it to sign in on your new phone.

Can I transfer data to a phone from a different brand?

Yes, as long as both phones run Android. Sign into your Google Account on the new phone and it will restore your Google data. For files and photos, use the USB cable method. Some data from brand-specific apps (like Samsung Health or OnePlus Notes) may not transfer to a different brand's phone.

How long does the transfer take?

Google Account backup usually completes within a few minutes for contacts and calendar, but photos and large files can take longer depending on how much data you have and your internet speed. Samsung Smart Switch over Wi-Fi typically takes 10 minutes to an hour. USB cable transfers are usually faster, taking 5 to 20 minutes.
