How to Back Up an Android Phone to a Computer: Photos, Files and More

Phones get lost, dropped in water and reset. If you want to back up an Android phone to a computer, the good news is that it is free and needs no special software for the most important part: your photos and videos. The catch is that, unlike an iPhone, most Android phones do not have one button that copies absolutely everything to a PC. This guide shows the reliable combination: a USB copy of your files, a full Smart Switch backup if you have a Samsung, and Google’s own backup for contacts and settings.

This is an independent guide, not affiliated with Google, Samsung or any phone maker. Menu names vary a little between brands; where they differ we give both.

What to back up, and where it goes

Data	Best way to back it up
Photos and videos	USB copy to the computer (and optionally Google Photos)
Downloads, documents, voice recordings	USB copy to the computer
Contacts, calendar	Your Google Account (synced automatically)
Texts, call history, settings, app list	Google backup (Backup by Google One)
WhatsApp and other chats	The chat app’s own backup
Everything on a Samsung Galaxy	Samsung Smart Switch on the computer

Method 1: Copy photos and files over USB (Windows)

1. Use a USB cable that carries data. Some cheap cables only charge; if nothing appears on the PC, try another cable.
2. Plug the phone into the computer and unlock it.
3. Pull down the notification shade, tap the USB notification (for example “Charging this device via USB”) and choose File transfer. On some phones it is called Transfer files or MTP.
4. On the PC, open File Explorer and click the phone under This PC (or in the left sidebar).
5. Open Internal storage (sometimes called Internal shared storage or Phone).
6. Create a dated folder on your PC, such as Documents\Phone backup 2026-10, and copy these folders into it: DCIM (camera photos and videos), Pictures (screenshots and saved images), Download, Documents, Movies, Music and Recordings if you use them.

Copy rather than move, so the originals stay on the phone until you have checked the backup. Large photo libraries can take a long time; keep the phone unlocked if the copy stalls. If you only want your pictures, our guide to transferring photos from a phone to a computer has more detail, including the Windows Photos import option.

If Windows does not see the phone at all, try another USB port, restart both devices, and read USB device not recognized.

Method 2: Samsung Smart Switch (full backup for Galaxy phones)

Samsung’s free Smart Switch app for Windows and Mac can back up much more than a file copy: messages, call logs, contacts, settings, home screen layout and many apps.

1. Download Smart Switch for PC or Mac from Samsung’s own website (not from a search ad or a third-party download site).
2. Install it, open it and connect the phone with a USB cable. Tap Allow on the phone when asked.
3. Click Backup, choose what to include and start the backup.
4. When it finishes, note where Smart Switch saved it. You can later use Restore to put it back on the same or a new Galaxy phone.

Smart Switch backups are designed to be restored with Smart Switch; you cannot browse them like normal folders, so still do the USB copy of your photos for easy access.

Method 3: Turn on Google backup for contacts and settings

Your contacts, texts, call history, app list and many settings are easiest to protect in your Google Account. This is not a backup to the computer, but it complements it.

1. Open Settings.
2. On a Pixel, go to System > Backup. On a Samsung, go to Accounts and backup > Back up data under Google Drive. On other phones, search Settings for Backup.
3. Make sure Backup by Google One is on and tap Back up now.

Google backup uses your Google Account storage. Photos are handled separately by Google Photos if you turn its backup on. Before relying on any cloud backup, make sure the Google Account itself is secure; see set up two-factor authentication and keep a recovery phone and email current.

Backing up to a Mac

macOS does not open Android phones over USB by itself. Your options:

• Samsung phones: install Smart Switch for Mac and follow Method 2.
• Any phone: turn on Google Photos backup and download your photos on the Mac from photos.google.com, or upload files to Google Drive and download them on the Mac.
• Wireless transfer apps: if you use one, pick a well-known app from the Play Store and the Mac App Store and avoid tools offered in pop-up ads.

Do not forget chat apps

Messaging apps store chats in their own format. WhatsApp backs up chats to Google Drive from Settings > Chats > Chat backup. Signal, Telegram and others have their own options. Check each one shows a recent backup date before you reset or replace the phone.

Check the backup worked

• Open a few photos and videos from the PC copy to make sure they play.
• Compare the number of items in DCIM on the phone and on the PC.
• In Smart Switch or Google backup, check the date of the last backup.
• Keep a second copy: an external drive or cloud folder protects you if the computer fails. Our 3-2-1 backup guide explains why.

Common problems

• Only “Charging” appears: choose File transfer in the USB notification, unlock the phone and try another cable.
• The copy stops part way: keep the phone unlocked, copy one folder at a time, and use a USB port directly on the computer instead of a hub.
• Phone storage is almost full: once your backup is checked, our guide on Android storage full shows what you can safely delete.
• You deleted photos before backing up: see recover deleted photos on a phone quickly, before new data overwrites them.

If you are backing up because you are selling or recycling the phone, the next step is backing up and wiping the phone before selling. If you also own an iPhone, the process is different; see how to back up an iPhone to a computer.
