How to Factory Reset a Samsung Galaxy Phone

To factory reset a Samsung Galaxy phone, use Settings if you can unlock the device, or use Android Recovery if the phone is locked or unresponsive. A factory reset erases personal data from the phone, so back up important information and remove your Google and Samsung accounts before starting whenever possible.

How do I back up my Samsung Galaxy before a factory reset?

A factory reset removes downloaded apps, account information, messages, settings, and personal files stored in the phone’s internal storage. It does not serve as a reliable way to preserve photos, contacts, documents, authenticator data, or app records.

Before you factory reset a Samsung Galaxy, charge the battery and confirm that the backup contains what you need. Common backup options include Samsung Cloud for supported Samsung data, Smart Switch for copying supported content to another device or computer, and Google account backup for supported settings and app data.

1. Open Settings and look for Accounts and backup.
2. Select the backup option you use, such as Back up data under Samsung Cloud or Google Drive.
3. Review the categories included in the backup and start the backup.
4. Wait for completion, then check that important photos, contacts, documents, and messages appear in their intended destination.
5. Separately save anything that an app does not include, such as authenticator recovery codes or files kept only inside the app.

Removing a microSD card is a sensible precaution. A standard factory reset targets internal storage, but taking removable storage out prevents accidental changes and keeps the card separate during setup.

Why should I remove Google and Samsung accounts before resetting?

Factory Reset Protection, or FRP, is an Android security feature that can require a Google account previously used on the phone after an unauthorized reset. A recovery-mode reset does not bypass FRP.

If you can unlock the Samsung Galaxy and are preparing it for another person, remove its accounts before the reset:

1. Open Settings.
2. Select Accounts and backup, then Manage accounts.
3. Select each Google account, choose Remove account, and confirm.
4. Select the Samsung account and choose Remove account or Sign out, then complete any identity check shown.
5. Repeat the process for other personal accounts listed on the device.

Account-removal labels can vary with the installed software version. If you recently changed a Google password, make sure you can sign in successfully before resetting. Do not proceed unless you know the credentials for an account that may be requested during setup.

How do I factory reset a Samsung Galaxy from Settings?

The Settings method is the clearest way to factory reset a Samsung Galaxy phone when the screen works and you know the device PIN, pattern, or password.

1. Open Settings.
2. Select General management.
3. Select Reset.
4. Select Factory data reset.
5. Read the list of accounts, apps, and data that will be removed.
6. Scroll down and select Reset.
7. Enter the current PIN, pattern, or password if requested.
8. Select Delete all to confirm. If prompted, verify the Samsung account.

The Samsung Galaxy will restart and erase its internal data. It may reboot more than once before displaying the initial setup screen. Keep the phone charged, and do not force another restart while the reset is underway.

How do I factory reset a locked or unresponsive Samsung Galaxy?

Android Recovery is a separate startup menu used for maintenance when the normal Settings screen is unavailable. This method erases the phone but does not remove FRP or the need for previously linked account credentials.

1. Turn the phone off. If it does not respond, hold the Side and Volume Down buttons until it restarts, then begin the recovery-button step as the screen turns off.
2. For many recent Samsung Galaxy phones, connect the phone by USB to a powered computer.
3. Press and hold the Volume Up and Side buttons together.
4. Release the buttons when the Samsung logo or Android Recovery screen appears. If the phone starts normally, power it off and try the timing again.
5. Use the Volume Up and Volume Down buttons to highlight Wipe data/factory reset. The touchscreen usually does not operate in recovery mode.
6. Press the Side or Power button to select the highlighted item.
7. Highlight Factory data reset and press the Side or Power button to confirm.
8. When the wipe finishes, highlight Reboot system now and press the Side or Power button.

Button behavior can depend on the device design and installed software. If Android Recovery does not appear after careful retries, use Samsung’s official support guidance for the exact device rather than trying unrelated button combinations.

How do I set up a Samsung Galaxy after a factory reset?

After the factory reset, the Samsung Galaxy opens at its initial welcome screen. Connect to an available network and follow the setup prompts.

1. Choose the language and accessibility settings.
2. Connect to Wi-Fi or another available network.
3. Sign in with the Google account previously associated with the phone if FRP requests it.
4. Sign in to your Samsung account if you want to restore supported Samsung data.
5. Select the offered backup and choose the data to restore.
6. Create a new screen lock and finish the remaining setup prompts.

Restoration may continue after the home screen appears. Keep the phone connected and allow time for apps, photos, contacts, and settings to return. Data that was never backed up is not restored by the reset process.

What should I do if a factory reset does not fix my Samsung Galaxy?

A factory reset can resolve some software and configuration problems, but it cannot repair damaged hardware. Persistent failure to power on, repeated shutdowns, charging problems, display faults, overheating, or buttons that do not respond may require diagnosis by Samsung support.

Before contacting support, note the device model, what happened before the problem began, the exact symptoms, and the troubleshooting already completed. Open {site} and use the verified Samsung support option shown there. If the phone reaches setup but rejects an account, use the official Google or Samsung account-recovery process; repeated resets will not remove an account-verification requirement.
