How to Transfer Data to a New Android Phone

Got the new phone? I love that feeling. That new-box smell, the cold, perfect slab of glass. It’s that one day a year you get to feel like you’re living in the future.

And then comes the dread.

That slow, sinking feeling when you realize your entire digital life—all your photos, your messages, your two-factor codes, your everything—is still trapped on the old phone. And now you have to perform the digital equivalent of a brain transplant.

I’ve done this hundreds of times as a phone reviewer. I’ve seen every “magic” transfer tool fail in spectacular ways. Samsung’s Smart Switch, Google’s “Pixel” transfer, OnePlus’s Clone Phone… they’re all just okay, and they all miss things.

The key to not losing your mind (or your data) isn’t trusting one magic button. It’s about knowing what that button misses and handling it before you start.

The First Thing Everyone Forgets (And Regrets Most)

Before you even power on the new phone, pick up your old phone. We need to deal with the one thing that can lock you out of your entire life: your authenticator app.

I’m talking about Google Authenticator, Authy, or any other app that generates those 6-digit time-based codes (TOTP).

This is the 2FA time bomb. If you factory-reset your old phone before transferring these codes, you are locked out. Period. You will lose access to your email, your bank, your Discord, your crypto… everything. The stories I’ve seen from people who did this are pure panic.

The reason this is the #1 mistake is that Google Authenticator, for almost a decade, had no backup feature whatsoever. It trained an entire generation of users to believe the codes lived and died only on that physical device. The app itself even blocks screenshots, reinforcing this “security” theater that ultimately just locks you out.

Google finally added a transfer feature. You must use it.

1. On your OLD phone, open Authenticator.
2. Tap the three-dot menu > Transfer accounts > Export accounts.
3. Verify your identity. Select the accounts you want to move.
4. It will generate a QR code.
5. On your NEW phone, install Authenticator. Tap Transfer accounts > Import accounts and scan that QR code.

A better way: The “pro” move

Google’s “fix” is still a manual, device-to-device transfer. If your old phone is already dead or lost? You’re still locked out. This is a fundamentally flawed design.

Use this opportunity to migrate to an authenticator app that is designed for this.

• Option 1: Authy. This is the big-name alternative. It’s better because it has encrypted, multi-device (cloud) backup. This means you can install it on your new phone, log in, and your codes are just… there.
• Option 2 (My Preference): A Password Manager. Stop using a separate 2FA app entirely. Modern password managers (like 1Password, Bitwarden, etc.) can generate, store, and auto-fill your 2FA codes. Your 2FA codes just sync with the rest of your passwords. This is the simplest, most robust solution.

A quick note: The one criticism of Authy is that it’s notoriously difficult to get your secret “seeds” out of it if you ever want to leave. This is true. The real 100% foolproof method is to save the original QR code or text-based seed for every account when you first set up 2FA, and store that in your password manager. But for 99% of people, Authy or a password manager is the right move.

The “Big Transfer”: Cable, Wi-Fi, or the Cloud?

Okay, 2FA is handled. You can breathe. Now for the main event.

When you turn on your new Android phone, it will ask, “Copy apps & data?” This is where you make your first big decision. Your phone will offer to copy data wirelessly. This seems convenient. It is not.

I’ve seen this dozens of times. The transfer will whir along and then just… stop. It gets “stuck at 99%”. This is a common software handshake bug. The data has probably transferred, but the verification step fails, and users panic and cancel, which can corrupt the install.

Even when it works, wireless is slower and far more prone to interference.

The cable is your friend (use it!)

Your new phone (especially if it’s a Pixel) likely came with a “Quick Switch Adapter” or a USB-C to USB-C cable. Use it. A wired connection is dramatically faster and more reliable.

Pixel Pro Tip: A-ha! What if your Pixel only shows the Wi-Fi option? This is a frustrating bug I’ve seen. Google wants to push the wireless method, but it’s worse. The Fix: On the “Copy apps & data” screen, tap the image of the two phones 5 times. This is a hidden trick that forces the phone to look for a USB cable connection. This single tip will save you an hour of your life.

The “Gotcha”: But wait, why is it still slow? This is an expert-level frustration. Even in 2025, most flagship Android phones (like the Samsung Galaxy S25 Ultra) are shipping with slower USB 3.2 Gen 1 (5Gbps) ports, while the iPhone 16 Pro has 10Gbps ports. Worse, you are probably using the wrong cable. The white USB-C cable that came with your charger? It’s almost certainly a “charge-only” or a slow USB 2.0 (480 Mbps) cable. You must use a proper USB 3.0+ data cable to get the speeds you’re paying for.

The setup will also offer “Can’t use old phone?” which lets you restore from a Google (Google One) cloud backup. This is your fallback, or what you use if your old phone is lost or broken.

But… this brings us to the biggest lie in the Android ecosystem.

What Google and Samsung Say They’ll Transfer (and What They Actually Miss)

This is the most important section of this guide. Your Google Backup is not a 1:1 clone of your phone. It’s not even close. The manufacturer tools (like Samsung Smart Switch) are better, but they also fail.

Google’s “Backup by Google One” illusion

First, the confusing branding: “Backup by Google One” is just the new name for the regular Android backup that uses your Google account storage. It’s not really a separate, “better” service unless you pay for more storage.

The 25MB App Data Limit (The Smoking Gun): Here is the core problem, straight from Google’s own developer documentation: the “Auto Backup” feature for apps is limited to 25 MB per app.

What does this mean? It means your 10GB game save? Gone. Your multi-gigabyte podcast app cache? Gone. Your bank app’s secure device registration? Gone. The entire design of Google’s backup is to save small bits of data (like settings) and not count it against your Google Drive quota. It’s designed to be lightweight, not comprehensive. This is the fundamental, philosophical difference from an iPhone backup, and it’s the source of all user frustration.

What Google’s Backup Always Misses:

1. App Data over 25MB: As above. This is most games and large apps.
2. Your Downloads Folder: Any PDF, document, or file you downloaded? Still on the old phone.
3. Other Local Folders: That Music folder you manually curated? Your Documents? Ankidroid folders? All left behind.
4. Home Screen Layouts & Widgets: This is a “maybe.” It sometimes works, but just as often, it fails. Why? Google considers widget configurations “component data, not user data”.
5. Text Messages (MMS): Google says it backs up SMS/MMS. But in my experience, and in many user reports, this is a coin toss. One source flat-out says it can’t restore MMS. Don’t risk it.
6. “Non-Play Store” Apps: Sideloaded apps? Google doesn’t know they exist.

Manufacturer tools: The “better, but still broken” option

So, you’d think, “I’ll use the manufacturer’s tool! I’m going from Samsung to Samsung!”

Samsung Smart Switch: It tries to be a 1:1 clone. It’s better than Google’s. But the forums are filled with angry users. It still regularly fails to transfer app settings, app logins, and user-created folders. You still have to log in again to almost every app.

OnePlus Clone Phone: This one is even sketchier. I’ve seen users report it failing to connect, and my favorite is the “restore” option just vanishing from the app, forcing users to find a hidden settings menu. But here’s a brilliant observation from a user: using Clone Phone can cause battery drain on the new device. Why? It’s transferring old, conflicting system files and app data from a different OS version. This is the danger of a “clone.”

My Recommendation: Always use the wired transfer when you first set up the phone. This is a hybrid of Google’s process and the manufacturer’s. It’s the most comprehensive automatic option. But… you still have to do the manual checklist.

Wrangling WhatsApp: The Process That Deserves Its Own Section

And then… there’s WhatsApp. The single most-feared, most-frustrating part of switching phones. It has never been simple, and it’s still a minefield.

The “new” way (QR code transfer) vs. The “old” way (Google Drive)

The Old Way (Google Drive): This was the standard for years. You back up to GDrive on the old phone, then restore on the new one.

• The Problem: It’s notoriously unreliable. I’ve seen it get stuck, fail, or just… not find the backup.
• The Security “Gotcha”: To even use the Google Drive backup, WhatsApp often requires you to disable end-to-end encryption for the backup itself. You’re choosing between “convenience” and “security,” and it often fails anyway.

The New Way (QR Code Transfer): This is the official method now. It’s a direct, phone-to-phone, Wi-Fi-based transfer. This is what you should try first.

How to use the (new) WhatsApp Chat Transfer (the “right” way)

This process is very specific. Deviate, and it fails.

Prerequisites (The “Don’t-Mess-This-Up” List):

1. Your NEW phone must NOT be registered on WhatsApp yet. If you already activated it, you must uninstall WhatsApp or factory-reset the phone.
2. You must be using the same phone number.
3. Both phones must be on, plugged into power, and have Wi-Fi enabled (they don’t need to be on the same network, just have Wi-Fi on).

The Steps:

1. On your OLD phone: Go to Settings > Chats > Transfer chats > Start.
2. On your NEW phone: Install WhatsApp. Go through the setup, verify your number.
3. The “Transfer chat history from old phone” screen will appear. Tap Start.
4. A QR code will appear on the NEW phone.
5. Scan that QR code with your OLD phone.
6. Accept the connection, and wait. Do not leave the app.

This is much better, but it still doesn’t transfer your call history or any peer-to-peer payment messages.

Troubleshooting: “IT’S STUCK ON INITIALIZING!”

This is the bug. The transfer finishes, you open WhatsApp on the new phone, and it just says “Initializing…” forever.

This is a database migration bug. The transfer is choking on a corrupted or weird database entry. The most common culprit? Old, dead group chats.

The Fix: Before you even start the transfer, go through your old phone and leave and delete any old group chats you’re no longer active in. Clean up your database before you try to move it.

If it still fails, the Google Drive backup is your only fallback. If that fails, you are in third-party tool hell. I’ve seen the reviews for tools like MobileTrans and iCareFone. They are a high-risk, paid gamble. Some users say they work. Others call them scams. One user reported it worked… but it deleted all the recipient’s messages, leaving only their side of the chat. My advice? Avoid them unless you have zero other options.

Your Pre-Transfer Manual Checklist (The Things You Must Move Yourself)

This is it. This is the checklist I personally run through. Do this on your old phone before you wipe it.

1. __ 2FA Accounts: (I’m saying it again). Export Google Authenticator or confirm your Authy/Password Manager is synced.
2. __ WhatsApp: Manually trigger the “Transfer chats” feature.
3. __ Local Files (The Big One): Plug your old phone into a PC or Mac with a USB cable.
   • Open the phone’s storage.
   • Manually copy and paste these folders to your computer:
     • Downloads
     • Documents
     • Music
     • Pictures / DCIM (Even if you use Google Photos, a local backup is smart).
     • Any other folder you use (e.g., Ankidroid, Podcasts).
   • You can then move these to your new phone.
4. __ Text Messages (SMS/MMS): Don’t trust Google.
   • The Fix: Install the “SMS Backup & Restore” app. It’s been the gold standard for a decade.
   • Back up your SMS and Call Logs to an XML file.
   • Save that XML file to your Google Drive or computer.
   • Install the same app on your new phone and run the “Restore” function. It works. Every time.
5. __ De-Register Banking/Security Apps: This is a critical one.
   • Many high-security apps (especially banking apps, or secure messengers like Signal) tie themselves to the device hardware.
   • You must open the app on your old phone and find a “de-register this device” or “unlink device” option in the settings. If you don’t, the app on your new phone will simply not work.
6. __ Passwords: Make sure your password manager (Google, 1Password, etc.) is fully synced and you know your master password.

The Nightmare Scenario: “My Old Phone’s Screen is Smashed”

Okay, what if you can’t do any of this because the old phone is in pieces? All hope is not lost. It just depends on what is broken.

The golden rule (the bad news)

Almost all of these fixes require one thing: that you had USB Debugging enabled before you broke the phone.

This is the real disaster. The broken screen is just a symptom. The disease is that Android’s security model (rightfully) blocks USB data access until the phone is unlocked and “trusts” the connected computer. If you can’t see the “Trust this PC?” prompt, you can’t click “Yes.”

Pro Tip for your NEW Phone: Go to Settings > About Phone and tap “Build Number” 7 times. This unlocks “Developer options.” In that new menu, enable “USB Debugging.” Do this today. It’s your free “get out of jail” card for a future disaster.

Scenario 1: Screen is BLACK, but Touch Still Works (You hear “clicks”)

The Fix: You just need to see what you’re doing. The Hardware: Get a simple USB-C to HDMI adapter. The Process: Plug the phone into the adapter, and the adapter into a TV or monitor. Your phone’s screen will be mirrored. You can now “guess” where to tap on the black screen to unlock it and back up your data.

Scenario 2: Screen is BLACK, and Touch is DEAD

This is the big one. You can’t see, and you can’t touch. The Fix: You need to give your phone a new “body.” The Hardware: You need a USB-C Hub or Dock. One that has (at minimum) an HDMI port and a regular USB-A port. The Process:

1. Plug the hub into your phone.
2. Plug the HDMI cable into the hub and your monitor (now you can see).
3. Plug a wired USB mouse into the hub’s USB-A port (now you can click).
4. A mouse cursor will appear on your monitor. You can now use the mouse to click your PIN/pattern, unlock your phone, and perform all the manual backup steps.

If you have a Samsung, this is even easier. Doing this will often launch DeX, a full desktop-like interface, on your monitor.

If USB Debugging was OFF and the screen is locked and dead, you are in a very, very bad spot. Your only hope is that a cloud backup ran before the phone died. This is why enabling Google Photos and the (limited) Google One backup is non-negotiable. It’s your only defense against total data loss.

“Is It Done?” The Post-Transfer Shakedown

You did it. The new phone has your apps. Your WhatsApp chats are here. You’re logged into your bank. You’re done, right?

No. Do not wipe your old phone.

Not yet. This is my last, and most important, piece of advice.

The One-Week Rule: Keep your old phone in a drawer. Charged. For one week.

The “Login Gauntlet”: Use your new phone for that week. Go through your “Login Gauntlet.” This is where you actually open and use every important app.

• You will find one app (probably your work email or a random game) that you forgot to transfer.
• You will find one service that needs 2FA, and you’ll be so glad you can still grab the code from the old phone.

The Peripheral Check: Re-pair everything.

• Your headphones.
• Your smartwatch.
• Your car’s Bluetooth.
• Your smart-home speakers.
• These do not transfer.

The Final Act: After a week. After you’ve gotten paid, After you’ve logged into your bank. After you’ve confirmed your photos from the weekend are backing up… then, and only then, can you pick up your old phone.

Go to Settings. Find “Factory data reset.” And tap it.

Then you’re done. Enjoy the new phone. You earned it.
