How to Back Up Your Photos Before Switching to a New Phone

Getting a new phone is the moment most people find out whether their photos were really backed up. The transfer usually works. But "usually" is doing a lot of work in that sentence — and if the old phone has already been wiped or handed back for trade-in, there is no second chance.

The fix is simple: make an independent copy of your photos before you switch, and don't wipe the old phone until you've checked the new one. This guide covers how, for every direction — iPhone to iPhone, Android to Android, and between the two.

Why back up first if the transfer moves everything?

Because a transfer moves data; it isn't a backup.

Transfer tools are designed to get your new phone set up quickly, and they're good at it. But a transfer can be interrupted, can skip items, or can depend on photos being available that aren't actually on the old phone — which is common when they live in iCloud or Google Photos. And the moment you reset the old phone, the transfer becomes the only path your photos took.

A copy on a USB drive changes that. If anything goes wrong, you still have every photo, on hardware you hold.

Step 1: Make an independent copy

Before you start any transfer, copy your whole photo library to a USB drive.

• Use a drive formatted exFAT — both iPhone and Android can read and write it, which matters if you're switching platforms. (exFAT vs FAT32 for phone backups explains why.)
• Make sure it's big enough for your entire library, including videos.
• If you use iCloud Photos with Optimize iPhone Storage on, make sure the copy contains your originals, not the space-saving versions on the phone.

The step-by-step guides for iPhone and Android cover the details.

Step 2: Transfer to the new phone

iPhone to iPhone

• Quick Start sets up the new iPhone directly from the old one, held side by side.
• iCloud Backup restores the new iPhone from a backup of the old one. If you don't have enough iCloud storage, Apple offers temporary iCloud storage when you buy a new iPhone: on the old phone, go to Settings → General → Transfer or Reset iPhone → Prepare for New iPhone. You get 21 days to restore that backup, and can extend it by another 21.
• If you use iCloud Photos, your library syncs to the new phone once you sign in. With Optimize iPhone Storage on, it may take time for originals to download.

Android to Android

Most Android phones offer to copy apps and data from your old phone during setup, using a cable or Wi-Fi, and some manufacturers have their own transfer apps. If your photos are backed up in Google Photos, they'll be available once you sign in.

Android to iPhone

Apple's Move to iOS app, installed on the Android phone, transfers your data during iPhone setup — including camera photos and videos, photo albums, files and folders, contacts, messages, and WhatsApp chats and media.

iPhone to Android

Google's switching process copies data from your iPhone during Android setup — photos, videos, contacts, messages, and more. Google recommends using a cable, which transfers the most, and some phones need an OTG adapter; without one, a wireless app is available.

One thing to watch: if your iPhone uses iCloud Photos with Optimize iPhone Storage on, many of your originals aren't on the iPhone at all. For photos in iCloud, Google points people to a separate process — requesting a copy of their iCloud photos at privacy.apple.com. A drive copy made with your originals sidesteps this entirely.

Using a USB drive to carry photos between platforms

Because an exFAT drive works with both iPhone and Android, it's a neutral way to move photos across — and it stays behind as your backup.

Copying photos onto a new iPhone:

1. Connect the drive and open the Files app.
2. Browse to your photos on the drive.
3. Select the photos and videos, tap Share, and save them to your library.

Copying photos onto a new Android phone:

1. Connect the drive and open your file manager.
2. Copy the folders into your phone's storage — for example into Pictures.

Each photo keeps its capture date and location, because they're stored inside the file. (On Android, your file manager may show today's date for copied files; the real date is still inside the photo, which is what photo apps read.)

Step 3: Check before you wipe the old phone

Don't reset, sell, or trade in the old phone until you've checked three things:

1. The photo count roughly matches between old and new phones.
2. Older photos and long videos open on the new phone at full quality — not just recent ones.
3. The drive copy opens — try a few photos and a video straight from the drive.

Then follow your phone maker's steps for selling or trading in a device, which include signing out of your accounts. After that, the drive copy is your safety net — keep it.

How VaultDrive helps when you switch

VaultDrive makes Step 1 quick and complete, straight from the old phone with no computer:

• The whole library, in one run. Everything, or the albums you choose — no selecting thousands of photos by hand.
• Your originals, not previews. On iPhone, if originals live in iCloud, VaultDrive downloads them first, one at a time, over Wi-Fi by default.
• Readable by both platforms. Photos land as ordinary files in ordinary folders — albums become folders on iPhone, and your folder structure is mirrored on Android — so the same exFAT drive opens on your new phone, whichever kind it is.
• Old and new phones, side by side. Each phone backs up into its own folder on the drive, so you can keep backing up the new phone to the same drive afterwards.
• Checked copies. Every file is checked against the original's size, with an optional SHA-256 check, and anything that fails is reported.
• It warns you about the drive. VaultDrive flags FAT32 drives, which can't hold videos over 4 GB, before you start.

VaultDrive doesn't currently restore photos back into your photo library itself. Because its backups are plain files, you copy them onto the new phone with the steps above, using the Files app or your file manager.

It's free for up to 200 files or 2 GB per backup. Pro is a one-time purchase that removes the limit and makes later backups copy only what's new. It's tied to the App Store or Google Play account you bought it with, so if you're switching platforms, the free version still lets you back up and you can buy Pro on the new platform if you want it.

Frequently Asked Questions

Should I back up my photos before switching phones?

Yes. Transfer tools move your data from the old phone to the new one, but they are not a backup. If a transfer is interrupted or skips something, and the old phone has already been wiped or traded in, there is nothing to go back to. An independent copy on a USB drive means the transfer can fail without costing you any photos.

How do I transfer photos from an Android phone to an iPhone?

Apple's Move to iOS app transfers camera photos and videos, photo albums, files, messages, contacts, and more from an Android phone during iPhone setup. You can also copy your photos to a USB drive first: an exFAT drive works with both phones, so the same drive can carry your photos across and stay as a backup afterwards.

How do I transfer photos from an iPhone to an Android phone?

Google's switching process copies photos, videos, contacts, and more from an iPhone during Android setup, using a cable or, without one, a wireless app. If your photos are in iCloud Photos with Optimize iPhone Storage on, many originals are not on the iPhone itself, and Google points iCloud users to requesting a copy of their iCloud photos at privacy.apple.com.

Can I use the same USB drive with an iPhone and an Android phone?

Yes, if it's formatted exFAT, which both read and write. That makes a USB drive a neutral way to carry photos between platforms. Copy everything from the old phone, then copy the photos onto the new one with the iPhone's Files app or the Android file manager.

How do I get photos from a USB drive onto my new phone?

On an iPhone, connect the drive, open the Files app, select the photos and videos, tap Share, and save them to your library. On Android, copy them with your file manager into a folder such as Pictures. VaultDrive does not currently restore photos into the library itself, but because its backups are ordinary files, the phone's own tools can do it.

When is it safe to wipe my old phone?

Only after you have checked that the photos arrived on the new phone and that you have a separate copy, such as on a USB drive. Compare photo counts, open some older photos and videos on the new phone, and confirm the drive copy opens. Then follow your phone maker's steps for selling or trading in a device.

The short version

Back up first, transfer second, wipe last.

Copy your whole library to an exFAT USB drive before you start — with VaultDrive it's one run from the old phone, originals included. Then use Quick Start, Move to iOS, or Google's switching tool to set up the new phone. Check the photos arrived, check the drive opens, and only then reset the old phone.

Whatever happens in between, your photos are on a drive in your hand.
