What a button reset does and when you need it

A hard reset using physical buttons — also called a factory reset or master reset — erases everything on your Samsung phone and restores it to the state it was in when it left the factory. This means all your photos, messages, apps, and settings disappear. The phone itself keeps working; you are not breaking it. You are clearing the storage.

You would do this if your phone is frozen and will not respond to touch, if you forgot your PIN or pattern and cannot get past the lock screen, if you are selling or giving away the phone, or if the software has become so corrupted that normal fixes do not work. If your phone still responds to touch and you can reach the Settings menu, a regular factory reset through Settings is safer and easier — but if the screen is unresponsive or locked, the button method is your way in.

Warning: this process erases everything. If you have not backed up your photos, contacts, or other data, you will lose them. If you can still turn the phone on and reach Settings, back up to Samsung Cloud or Google Drive before you start.

Key Takeaways

  • A hard reset using buttons works when your Samsung phone is frozen, unresponsive, or locked with a forgotten PIN, and erases all data on the device.
  • The button combination varies by Samsung model — most use Power + Volume Up, but some older models use Power + Volume Down, so check your exact model first.
  • You must hold the buttons until the Samsung logo appears, then release and wait for the recovery menu to load, which takes 10 to 30 seconds.
  • Once in recovery mode, use Volume Down to highlight "Wipe data / factory reset" and Power to select it, then confirm the wipe on the next screen.
  • The phone will reboot and ask you to set it up again from scratch, which takes a few minutes.

Find your exact Samsung model and button combination

The button combination depends on which Samsung phone you have. Most modern Samsung phones (Galaxy S10 and newer, Galaxy A series from 2019 onward) use Power + Volume Up. Some older models use Power + Volume Down instead. A few very old Samsung phones have different combinations.

The easiest way to find out is to look at the back of the phone or the original box — it will say "Galaxy S21" or "Galaxy A52" or similar. Then search online for "[your exact model] hard reset buttons" to confirm the combination before you start. This takes 30 seconds and saves you from holding the wrong buttons for nothing.

If you cannot find the model number, try Power + Volume Up first, since that is the most common. If that does not work, power off the phone completely, wait 10 seconds, and try Power + Volume Down instead.

Power off the phone and hold the button combination

Turn off your Samsung phone completely. Press and hold the Power button until the screen goes black and stays black — do not just let it go to sleep. Wait 5 to 10 seconds after the screen goes off to make sure it is fully shut down.

Now press and hold both the Power button and the Volume Up button (or Volume Down, depending on your model) at the same time. Keep holding both buttons. Nothing will happen for a few seconds — this is normal. Keep holding.

After 10 to 20 seconds, the Samsung logo will appear on the screen. The moment you see the logo, release both buttons. Do not hold them any longer. The phone is now entering recovery mode.

Wait for the recovery menu and navigate to factory reset

After you release the buttons, the screen will show "Recovery mode" or "Android Recovery" at the top, and below that you will see a menu with options like "Reboot system now", "Wipe data / factory reset", and others. This menu is controlled by the volume buttons, not by touch — your screen may not respond to taps.

Use the Volume Down button to move the highlight down through the menu until "Wipe data / factory reset" is highlighted in white or a different color. This usually takes 2 to 4 presses of Volume Down. Do not press anything else.

Once "Wipe data / factory reset" is highlighted, press the Power button to select it. The phone will ask you to confirm — you will see a screen that says something like "Wipe all user data?" with "Yes" and "No" options.

Confirm the wipe and wait for the reset to finish

Use Volume Down to highlight "Yes" (or "Delete all user data"), then press Power to confirm. The phone will now erase everything. You will see a progress bar or a message saying "Wiping data" or "Formatting". This can take anywhere from 30 seconds to 3 minutes depending on how much data is on the phone.

Do not turn off the phone or remove the battery during this time. Let it finish completely. When it is done, you will see "Wipe data complete" or the menu will return.

Press Power to reboot the system, or use Volume Down to highlight "Reboot system now" and press Power. The phone will restart and show the Samsung logo, then boot into the setup screen.

Set up your phone from scratch

Your Samsung phone will now ask you to choose a language, connect to Wi-Fi, and sign in with a Google account or Samsung account. This is the same setup you would see on a brand-new phone. Go through these steps as you normally would.

If you backed up your data to Google Drive or Samsung Cloud before the reset, you can restore your photos, contacts, and some app data during setup — the phone will ask if you want to restore from a backup. If you did not back up, your data is gone and you will be starting fresh.

Once setup is complete, your phone is back to factory condition and ready to use.

What to do if the buttons do not work or the phone will not reset

If you hold the buttons and nothing happens, the phone may be completely out of battery. Plug it into a charger for at least 15 minutes, then try again. A phone with a dead battery cannot enter recovery mode.

If the phone enters recovery mode but the buttons do not navigate the menu, try pressing Volume Down and Volume Up separately rather than together. Some phones respond to single button presses instead of combinations.

If the phone is stuck in a boot loop (restarting over and over) or will not complete the reset, the issue may be deeper than a factory reset can fix. At this point, contact Samsung support or visit a Samsung service center. They have tools to reflash the software or replace the phone if it is still under warranty.

Frequently Asked Questions

Will a hard reset remove my Google account lock?

No. After the reset, the phone will ask you to sign in with a Google account. If you do not remember the account that was on the phone before the reset, you will not be able to get past this screen. This is a security feature called Factory Reset Protection. If this is your phone, sign in with your own Google account. If it is not your phone, you cannot proceed without the original owner's account information.

Can I stop the reset once it starts?

Once the wipe begins, you should not interrupt it. If you turn off the phone during the wipe, it may not boot properly afterward. Let it finish, even if it takes a few minutes. If something goes wrong, you can always try the reset again.

What if I only want to erase some data, not everything?

A hard reset erases everything — there is no middle ground with the button method. If you want to delete only certain files or apps, use Settings > Apps to uninstall apps one at a time, or Settings > Storage to delete photos and files manually. This only works if your phone is responsive enough to use the touch screen.

Do I need to remove my SIM card before resetting?

No. The SIM card stores your phone number and carrier information, not your personal data. It will not be affected by a factory reset. You can leave it in the phone during the reset.

How long does a factory reset take?

The actual wipe takes 30 seconds to 3 minutes. The reboot and initial setup after that takes another 2 to 5 minutes. In total, plan for 10 minutes from start to finish, including the time it takes to navigate the recovery menu.
