Are you experiencing issues with your Samsung Galaxy A21s, or perhaps you plan to sell or hand it over to someone else? A factory reset can be the perfect solution to restore your device to its original condition, freeing it from software glitches and personal data. In this comprehensive guide, we’ll delve deeply into the methods of performing a factory reset on your Samsung Galaxy A21s, the reasons you might need to reset your device, and the steps to take before, during, and after the reset process.
Understanding Factory Reset
A factory reset is a process that restores your device to the state it was in when it first left the factory. This means that all user data, installed applications, and settings will be erased. Here’s a breakdown of what to expect:
- Erasure of Data: All personal files like photos, videos, contacts, and applications will be deleted.
- Restoration of Settings: Your device settings and configurations will be reverted to default, removing any custom changes you’ve made.
- Potential Fix for Issues: A factory reset can significantly help in resolving performance issues, software bugs, and unresponsive apps.
Why You Might Need a Factory Reset
There are several reasons users might choose to perform a factory reset on their Samsung Galaxy A21s:
1. Device Performance Issues
If you notice that your device is running slower than usual or apps frequently crash, a factory reset may help to clear out any underlying problems.
2. Preparing for Sale or Donation
When selling or giving away your smartphone, it’s vital to wipe all your personal data to protect your privacy. A factory reset ensures that all your information is erased.
3. Stubborn Software Bugs or Glitches
Encountering persistent software bugs that are not resolved by normal troubleshooting techniques may necessitate a factory reset.
4. Restoring Settings After an Update
If your device faces issues after a significant software update, a factory reset can help start afresh.

What is a factory reset, and why would I need to perform one on my Samsung Galaxy A21s?
A factory reset, also known as a hard reset, is a process that erases all the data, settings, and applications on your device, restoring it to its original factory state. This action is particularly useful if your device is experiencing persistent problems such as software glitches, performance issues, or if you plan to sell or give away your phone. It can help improve the overall performance and responsiveness of your device.
In addition to troubleshooting purposes, performing a factory reset is essential when you encounter issues like forgetting your device’s password or being unable to access your phone. A factory reset erases all personal information, ensuring that your data is secure when transferring ownership of the device. However, it’s essential to back up your data before proceeding with a factory reset as this action is irreversible.
How do I back up my data before a factory reset on my Samsung Galaxy A21s?
Backing up your data is crucial before initiating a factory reset. You can back up your data using Samsung Cloud or Google Drive, where you can save your photos, contacts, and app data. To use Samsung Cloud, go to “Settings,” tap on “Accounts and Backup,” and then select “Back Up Data.” Ensure that all the necessary data types are selected and proceed to back it up.
Alternatively, you can use Google Drive for backing up your data. Navigate to “Settings,” select “Google,” then “Backup,” and make sure “Back up to Google Drive” is enabled. This method will save your important data like contacts, calendar events, and app data to your Google account, allowing you to restore them seamlessly after the factory reset.
What are the steps to perform a factory reset on my Samsung Galaxy A21s?
To perform a factory reset on your Samsung Galaxy A21s, begin by opening the “Settings” app on your device. Scroll down and click on “General Management.” From there, select “Reset,” and then tap on “Factory Data Reset.” You will see information regarding the data that will be erased during this process.
After reviewing this information, scroll down and tap on “Reset.” You might be prompted to enter your PIN or password for security purposes. Finally, confirm the action by tapping on “Delete All.” Your device will restart, and the factory reset process will begin, which may take several minutes before your phone returns to its initial setup screen.
Will a factory reset delete my Samsung account and other accounts?
No, performing a factory reset on your Samsung Galaxy A21s will not delete your Samsung account or any linked accounts like Google. However, it will log you out of these accounts on the device. After the reset, you will need to enter your credentials to access those accounts again. This ensures that your account information remains secure and intact, even as your device is returned to factory settings.
It’s important to note that while your accounts are safe, all localized data, such as your contacts, messages, and any downloaded apps, will be erased. Therefore, backing up your accounts and data beforehand is critical to ensure a smooth restoration process once the device is reset and you re-login to your accounts.
What should I do if I encounter a problem after the factory reset?
If you face issues after performing a factory reset on your Samsung Galaxy A21s, first ensure that all software updates are installed on your device. Sometimes, bugs or problems can occur due to outdated software. Navigate to “Settings,” scroll to “Software Update,” and select “Download and Install” to check for any available updates.
If issues persist even after updating, consider wiping the cache partition of your device. This process does not delete your data but can help resolve performance-related issues post-reset. To do this, turn off your device, then press and hold the Volume Up and Power buttons simultaneously until the Android logo appears. From the recovery menu, navigate to “Wipe Cache Partition” using the volume buttons and select it with the Power button.
Can I restore my data after performing a factory reset?
Yes, you can restore your data after performing a factory reset on your Samsung Galaxy A21s, but only if you have taken the necessary backup steps beforehand. If you utilized Samsung Cloud or Google Drive to back up your data, you can restore it when setting up your device post-reset. During the initial setup process, you will be prompted to log into your Samsung or Google account, where you can then choose to restore your backed-up data.
If you have additional backups saved on external storage or other cloud services, make sure to access those platforms to retrieve your data. Follow the specific restore instructions provided by those services to ensure all your important files and contacts are successfully restored to your device.
How can I ensure that my Samsung Galaxy A21s is ready for a factory reset?
Before performing a factory reset on your Samsung Galaxy A21s, it is essential to ensure the device is adequately prepared. First, charge your phone to at least 50% to avoid any interruptions during the reset process. Running the reset on a low battery can lead to complications or even damage your device.
Next, back up all important data, including photos, documents, and contacts. Double-check that you have backed up everything you need, as a factory reset will erase all data on the device permanently. Once these preparations are complete, your device will be ready for a smooth and effective factory reset.
Will factory resetting my Samsung Galaxy A21s remove viruses or malware?
Yes, performing a factory reset on your Samsung Galaxy A21s is an effective method for removing viruses and malware that may have infected your device. By reverting your phone to its initial factory settings, all apps, data, and files—including potentially harmful software—are wiped clean. This action restores your device to a clean state, which can enhance your phone’s security and performance.
However, it’s essential to note that if the malware resides in your SD card or is reintroduced from a backup after resetting, it can impact your device again. To ensure complete security, consider scanning all restored data with a reputable antivirus program before reintroducing it back onto your device. This way, you can enjoy a fresh start without any lingering threats.
