Hard Factory Reset Samsung A20: Full Guide

To hard factory reset a Samsung Galaxy A20, turn off the phone, then press and hold Volume Up and Power until the Samsung logo appears, release the buttons, and use the volume keys to select “Wipe data/factory reset” from the recovery menu. This erases all data and restores the phone to its original out-of-the-box state, which is useful for fixing major software issues or preparing the device for a new owner.

What Is a Hard Factory Reset?

A hard factory reset (also called a master reset) restores a device to its default system state by deleting all user data, settings, and downloaded apps. On the Samsung Galaxy A20, this process wipes the internal storage, including photos, messages, contacts, and app data, and reinstalls the operating system from a hidden recovery partition. It is different from a soft reset (simply restarting the phone) and from a “factory data reset” done through the Settings menu, though both ultimately clear user data. The hard reset method is performed from the recovery mode, which is a separate boot environment that runs even when the main Android system fails to start.

When You Might Need a Hard Reset

There are several common situations where a hard factory reset is the appropriate solution:

• Forgotten lock screen password, PIN, or pattern – If you cannot unlock the phone, a hard reset bypasses the lock screen (though it may still require your Google account credentials afterward if Factory Reset Protection is enabled).
• Persistent software crashes or freezes – When the phone repeatedly restarts, freezes on the logo, or shows constant error messages, a reset can clear corrupted system files.
• Malware or suspicious apps that cannot be removed – A reset removes all apps and their data, which is often the only way to eliminate deeply embedded malicious software.
• Preparing to sell or give away the phone – A hard reset ensures your personal data is gone, though for maximum security you should also encrypt the device before resetting or use a secure data-wiping tool.
• Major OS update problems – If an Android update leaves the phone in a boot loop or with severe battery drain, a reset can start fresh.

Before You Reset: Backup and Precautions

Because a hard reset permanently deletes everything on the phone’s internal storage, you must back up important data first. The Galaxy A20 offers several backup options:

• Samsung Cloud – Go to Settings > Accounts and backup > Backup and restore, then enable “Back up data” for your Samsung account.
• Google Drive – Ensure “Back up my data” is on in Settings > Accounts and backup > Backup and restore > Google account. This saves app data, call history, contacts, and settings.
• Manual transfer – Copy photos, videos, and documents to a microSD card, a computer, or a USB drive. The A20 supports microSD cards up to 512 GB.
• Remove the Google account – If you plan to sell the phone, go to Settings > Accounts and backup > Accounts, remove your Google account, and sign out of your Samsung account. This disables Factory Reset Protection (FRP), which would otherwise ask for your previous Google password after the reset.

Also ensure the battery has at least 50% charge, because a power failure during the reset can corrupt the system. If the phone is off and you cannot turn it on, plug it into a charger for a few minutes before attempting the reset.

Step-by-Step: Hard Reset Using Hardware Keys

This method works even if your phone is stuck on the boot screen or the screen is unresponsive. Follow these steps exactly:

1. Turn off the Samsung Galaxy A20. If it is frozen, press and hold the Power button and Volume Down for about 10 seconds until the screen goes dark.
2. Press and hold the Volume Up and Power buttons simultaneously.
3. Keep holding both buttons until the Samsung logo appears, then release them. The phone will boot into Android Recovery mode (a blue screen with text options).
4. Use the Volume Down key to navigate to “Wipe data/factory reset.” The Volume Up key is used to select (or you can press the Power button, depending on the model).
5. Select “Wipe data/factory reset” and confirm by choosing “Yes” when prompted.
6. Wait for the reset to complete – this can take a couple of minutes. You will see a message saying “Data wiped complete.”
7. Select “Reboot system now” using the Volume keys and press Power. The phone will restart and may take longer than usual on the first boot.

If the phone does not enter recovery mode with Volume Up + Power, try Volume Down + Power, or connect the phone to a computer via USB and use Smart Switch (Samsung’s desktop software) to perform an emergency recovery.

Alternative: Factory Reset from Settings

If your phone boots normally and you can access the settings menu, you can do a factory reset without using hardware keys. Go to Settings > General Management > Reset > Factory data reset. Scroll down and tap “Reset,” then “Delete all.” The phone will restart and erase everything. This method is easier, but it does not work if the system is too unstable to open Settings or if you are locked out. Also note that a Settings reset is the same as a hard reset in terms of data deletion – the only difference is the method of initiation.

After the Reset: Setup and Recovery

Once the phone restarts, you will see the Android setup wizard. Choose your language, connect to Wi-Fi, and sign in with your Google account. If you backed up data, you can restore it during setup. If Factory Reset Protection was active and you did not remove your Google account beforehand, the phone will ask for the Google account credentials that were previously used on the device. This is a security feature to prevent thieves from using a stolen phone; you must enter the correct username and password to proceed. If you forgot the password, you will need to use Google’s account recovery tools or contact Samsung support (but they cannot bypass FRP for you).

Common Problems and Troubleshooting

Several issues can arise during or after a hard reset:

• Phone stuck in recovery mode – If the phone keeps booting into recovery instead of the normal system, select “Reboot system now” again, or try “Apply update from ADB” and then reboot. If it still loops, the system partition may be corrupted; you might need to flash the firmware using Odin (a Windows tool) or take the phone to a service center.
• Reset does not complete – If the reset freezes, force a restart by holding Power + Volume Down for 10 seconds, then try again. Ensure the battery is charged.
• Google account verification (FRP) lock – As mentioned, you must enter the previous Google account password. If you don’t know it, you cannot bypass this legally; you must recover the account through Google’s official process.
• Phone is slower after reset – This is normal for the first few hours as the phone re-indexes files and downloads app updates. Give it a day before judging performance.
• Lost data that was not backed up – A hard reset permanently deletes data. There is no built-in way to recover it after the reset. Third-party recovery tools might work if the data hasn’t been overwritten, but this is not guaranteed and often requires root access.

Frequently Asked Questions

Will a hard reset remove the Samsung and Google accounts? No, a factory reset does not remove your accounts from Samsung’s or Google’s servers. It only removes them from the phone. The FRP feature will still require the previous Google account to set up the phone again.

Can I do a hard reset without the power button? If the power button is broken, you can try connecting the phone to a computer and using ADB (Android Debug Bridge) to run the command adb reboot recovery. This requires USB debugging to have been enabled before the issue. Alternatively, use the Settings method if the phone is accessible.

Does a hard reset fix battery drain? Sometimes, if the drain is caused by a rogue app or corrupted system data, a reset can help. But if the battery is old or physically damaged, a reset won’t fix it – you’d need a battery replacement.

How long does a hard reset take? The wipe process itself takes about 2–5 minutes, but the first boot after the reset can take up to 10 minutes. The entire setup process, including signing in and restoring apps, can take 30–60 minutes.

Will I lose my microSD card data? No, a factory reset only affects the internal storage. Data on a microSD card is untouched. However, some apps may have encrypted data on the SD card that becomes unreadable after the reset, so it’s still wise to back up important files.

Is there any way to recover data after a hard reset? In most cases, no. The reset overwrites the storage encryption keys, making old data unrecoverable. If the data is critical, stop using the phone immediately and consult a professional data recovery service – but success is not guaranteed.
