How to Factory Reset a Locked Samsung Phone

To factory reset a locked Samsung phone that you own, use Android Recovery or an erase option in Samsung’s official device-management service. The reset deletes local data, but it does not bypass Factory Reset Protection or remove the need to verify a previously linked account.

If the phone may contain important files, review the checks below before erasing it. A factory reset cannot normally be undone.

What will a factory reset erase from a locked Samsung phone?

A factory reset removes information stored locally on the Samsung phone, including installed apps, app data, device settings, downloaded files, messages stored only on the device, and accounts added to the phone. Photos, recordings, notes, and documents that were never synchronized may also be lost.

Data already synchronized with a Google account, Samsung account, cloud service, computer, or removable memory card may remain in that separate location. A factory reset does not erase those outside copies. Remove the memory card before resetting if you want to protect its contents.

An eSIM may require separate handling depending on the model and reset menu. Read every confirmation screen before approving the reset.

What should you check before resetting a locked Samsung phone?

1. Charge the phone sufficiently or keep it connected to reliable power. An interruption during the reset can prevent normal startup.
2. Confirm that the phone belongs to you and locate its receipt, carrier record, serial number, or other proof of purchase.
3. Identify the Google account and Samsung account previously used on the phone. After the reset, the setup process may request one of those accounts.
4. Use another device to confirm that you know the account email addresses and passwords. Complete official account recovery before resetting if necessary.
5. Check whether photos, contacts, notes, and files are visible in the corresponding account or cloud service. A locked phone generally cannot create a new backup unless backup was already enabled.
6. Remove a memory card if the phone has one. Leave the SIM installed only if you may need mobile connectivity during setup.

Changing a Google account password shortly before a reset can sometimes lead to a security waiting period. If setup rejects a newly changed password, wait for the period shown by the official account service and try again.

How do you factory reset a locked Samsung phone using Recovery Mode?

Android Recovery is a built-in maintenance menu that works outside the normal lock screen. Button combinations differ by Samsung model, and some recent models must be connected by USB to a powered computer or another supported USB device before Recovery will open.

1. Turn off the Samsung phone. If the lock screen prevents a normal shutdown, hold the Side or Power button with Volume Down until the phone restarts, then immediately change to the Recovery button combination for the model.
2. For models with only Side and volume buttons, hold Volume Up and the Side button. For models with a separate Bixby button, hold Volume Up, Bixby, and Power. For older models with a physical Home button, hold Volume Up, Home, and Power.
3. Release the buttons when the Samsung logo or Android Recovery screen appears. If the phone starts normally, turn it off and repeat the model-appropriate combination; a USB connection may be required.
4. Use the volume buttons to highlight “Wipe data/factory reset.” Press the Power or Side button to select it.
5. Highlight the confirmation option, such as “Factory data reset,” and select it. This step erases the phone’s local user data.
6. Wait until Recovery reports that the wipe is complete. Highlight “Reboot system now” and select it.
7. Complete the initial setup and sign in with the previously linked account if ownership verification appears.

Menu wording and button timing can vary. If these combinations do not match the phone, use the model’s official Samsung user manual or ask Samsung Support for the correct Recovery procedure. Do not choose unrelated Recovery options.

Can Samsung’s official device service erase a locked phone remotely?

Samsung’s official device-management service may show a remote erase option when the phone was registered to a Samsung account, the relevant remote-management settings were enabled beforehand, and the device can connect to the internet. The option may differ by device, software version, region, and account configuration.

1. On another trusted device, open the company’s official website and locate Samsung’s device-finding or device-management service.
2. Sign in with the Samsung account already linked to the locked phone.
3. Select the correct phone by checking its displayed model and device details.
4. If an erase option is available, read the warning and complete the requested account verification.
5. Keep the locked phone powered on and connected. If it is offline, the command may remain pending or may not be available.

A remote erase also deletes local data and does not remove post-reset ownership checks. If the phone was never registered, cannot connect, or does not display an erase command, use Recovery Mode or contact Samsung Support.

Will Activation Lock remain after a Samsung factory reset?

Factory Reset Protection, or FRP, is an Android security feature that can require a Google account previously synchronized with the phone after an untrusted reset. Samsung account verification may also appear when Samsung protection or device services were associated with the phone.

A Samsung locked phone factory reset does not prove ownership and does not bypass these checks. During setup, enter the requested account that was genuinely linked before the reset. Do not use FRP-bypass programs, unofficial unlocking services, modified software, or password-cracking instructions.

What should you do if you cannot reset or sign in to the Samsung phone?

• Use Google’s official account-recovery process if the setup screen requests a previous Google account.
• Use Samsung’s official account-recovery process if the phone requests a Samsung account or its verification code.
• Check spam filtering, recovery email access, the selected country code, and mobile service if an official verification message does not arrive.
• Contact Samsung Support through the company’s official website if Recovery Mode will not open, the correct account is rejected, or the phone cannot finish setup.
• Prepare the phone’s model, serial number or IMEI, proof of purchase, account email address, and a description of the screen where the process stops.
• Contact the original carrier or seller if ownership records or device-financing status must be confirmed.

These are the safe options for how to reset a locked Samsung phone without a password. If official recovery cannot verify ownership, resetting the device again will not remove the account requirement.
