How Do I Reset My Android S21 Phone?: A Comprehensive Guide
Resetting your Android S21 phone allows you to restore it to its original factory settings, effectively erasing all personal data and configurations – a useful process before selling the device or troubleshooting persistent software issues; it’s crucial to back up your data before proceeding.
Why Reset Your Android S21?
There are several compelling reasons why you might need to reset your Android S21 phone:
- Troubleshooting Software Issues: A reset can resolve persistent glitches, slowdowns, or app crashes that resist other troubleshooting methods. It’s often the last resort for stubborn problems.
- Selling or Giving Away Your Phone: Before handing off your S21, a factory reset ensures your personal data is completely erased, protecting your privacy.
- Clearing Storage Space: Over time, your phone accumulates cache files, temporary data, and unused apps that consume storage. A reset effectively clears the slate.
- Improving Performance: By removing unnecessary files and configurations, a reset can breathe new life into a sluggish phone, making it feel faster and more responsive.
- Reversing Unwanted Modifications: If you’ve experimented with custom ROMs or other system-level tweaks, a reset can restore your phone to its original state.
Understanding the Different Reset Options
It’s important to understand the different types of resets available on your Android S21:
- Soft Reset (Restart): This simply reboots your phone, closing all running apps and clearing temporary memory. It doesn’t erase any data. To perform a soft reset, press and hold the power button, then tap “Restart.”
- Factory Reset (Hard Reset): This option erases all data on your phone, including apps, photos, videos, contacts, and settings, restoring it to its factory default state. This is the focus of this guide.
- Network Settings Reset: This resets all network-related settings, including Wi-Fi passwords, Bluetooth pairings, and mobile data preferences. It doesn’t affect your personal data. You can typically find this option under Settings -> General Management -> Reset -> Reset network settings.
Preparing for a Factory Reset
Before you reset your Android S21 phone, taking these preparatory steps is essential:
- Back Up Your Data: This is the most crucial step. Use your Google account, Samsung Cloud, or a third-party backup app to save your contacts, photos, videos, documents, and other important data.
- Remove Your Google Account: This prevents Factory Reset Protection (FRP) from locking your phone after the reset. Go to Settings -> Accounts and backup -> Manage accounts, select your Google account, and then tap “Remove account.”
- Charge Your Phone: Ensure your battery is at least 50% charged to prevent interruptions during the reset process.
- Remove Your SIM Card and SD Card (Optional): If you’re selling or giving away your phone, removing these cards ensures your personal information stored on them remains private.
Performing a Factory Reset Through Settings
Here’s how do I reset my Android S21 phone via the Settings menu:
- Go to Settings.
- Tap on General Management.
- Tap on Reset.
- Select Factory data reset.
- Review the information about what will be erased.
- Scroll to the bottom and tap Reset.
- If prompted, enter your PIN, password, or pattern.
- Tap Delete all to confirm.
Your phone will now restart and begin the reset process. This may take several minutes. Once complete, you’ll be greeted with the initial setup screen.
Performing a Hard Reset Using Recovery Mode
If you can’t access the Settings menu (for example, if your phone is locked or malfunctioning), you can perform a hard reset using Recovery Mode.
- Turn off your phone completely.
- Press and hold the Volume Up button and the Power button simultaneously.
- Release the buttons when the Samsung logo appears. This will boot your phone into Recovery Mode.
- Use the Volume Up and Volume Down buttons to navigate the menu.
- Scroll down to “Wipe data/factory reset” and press the Power button to select it.
- Use the Volume buttons to select “Yes” and press the Power button to confirm.
- Once the reset is complete, select “Reboot system now” using the Power button.
Your phone will now restart and begin the reset process.
Common Mistakes and Troubleshooting
- Forgetting to Back Up Data: This is the most common and devastating mistake. Always back up your data before performing a factory reset.
- Not Removing Your Google Account: This can trigger Factory Reset Protection (FRP), locking your phone after the reset and requiring your Google account credentials to unlock it.
- Interrupted Reset Process: Ensure your phone has sufficient battery and is not interrupted during the reset. Interruptions can corrupt the system and require professional assistance.
- Phone Not Turning On After Reset: Try connecting your phone to a charger and attempting to power it on again. If that doesn’t work, try booting into Recovery Mode. If neither works, you may need to seek professional help.

The duration can vary, but it typically takes between 5 and 15 minutes to complete.
What happens to my Samsung account after a factory reset?
