In today’s digital world, smartphones have become essential tools for communication, work, and entertainment. However, at times, users may encounter issues that require reverting their devices back to factory settings. Specifically, if you own a Samsung A21s secured by Knox, performing a hard reset can be a challenge. Whether you want to resolve software issues, prepare the device for a new user, or just clear all your personal data, this comprehensive guide will take you through the necessary steps to successfully hard reset your Samsung A21s.
Understanding the Samsung A21s and Knox Security
Before diving into the hard reset process, it is crucial to understand the key features of the Samsung A21s and the Knox security platform that safeguards your device.
Samsung A21s: The Basics
The Samsung A21s is a budget-friendly yet powerful smartphone that boasts impressive specifications. Its features include:
- 6.5-inch HD+ display
- Quad-camera setup for stunning photography
- 5000 mAh battery for extended usage
- Exynos 850 processor for smooth performance
This device is aimed at users who seek functionality and style without breaking the bank.
Knox Security: What You Need to Know
Knox is Samsung’s integrated security platform that protects your device from malware and unauthorized access. It is designed to keep personal and sensitive information safe. Your Samsung A21s may come pre-installed with this security feature, making it essential to understand its implications when performing a hard reset.
One critical aspect of Knox is that performing a factory reset on a device that has been secured with Knox may lead to the “Knox Warranty Void” message. This indicates that the security of the device may be compromised, impacting its warranty.
Reasons to Hard Reset Your Samsung A21s
There are several reasons why you might want to perform a hard reset on your Samsung A21s, including:
Resolving Software Issues
Over time, your smartphone may experience glitches, slow performance, or unexpected crashes. A hard reset can help restore the device to its original settings, potentially resolving these issues.
Preparing for a New User
If you intend to sell or give away your Samsung A21s, it’s essential to erase all personal data, ensuring the new user starts fresh without any leftover information.
Clearing Space
A hard reset can help clear cache and unnecessary files that accumulate over time, freeing up space and optimizing the device for better performance.
Important Considerations Before Hard Resetting Your Samsung A21s
Before you proceed with the hard reset, you should take certain precautions to avoid data loss and other issues.
Back Up Your Data
A hard reset will delete all data stored on your device, including apps, photos, and contacts. Make sure to back up your files to prevent losing any valuable information. You can use Samsung Cloud, Google Drive, or other backup services.
Ensure Battery is Charged
Make sure your device’s battery level is at least 50% charged before proceeding with the reset. A sudden battery drain during the process can result in software corruption.
Remove Google Account and Knox Security
If your device is secured by Knox, it may be crucial to remove any Google accounts linked to your device prior to resetting, as this could lead to a locked device afterward.

What is a hard reset, and why would I need to perform one on my Samsung A21s?
A hard reset, commonly known as a factory reset, restores your device to its original system state by erasing all user data and settings. You might need to perform a hard reset on your Samsung A21s to troubleshoot persistent software issues, improve performance, or prepare the device for resale. It can also be useful if you forget your lock screen password.
However, it’s essential to remember that a hard reset will erase all data stored on your device, including apps, photos, contacts, and any other personal information. Therefore, it is highly recommended to back up your important data before proceeding with this action to ensure you do not lose anything vital.
Will performing a hard reset remove Knox security from my Samsung A21s?
Performing a hard reset on your Samsung A21s will reset the device to its factory settings, but it does not remove the Knox security features. Knox is integrated into the device’s hardware and firmware, providing enhanced security for your data and applications. Thus, even after a hard reset, your Knox status will remain intact.
If your device is secured by Knox, note that certain features related to security and enterprise management may be affected. For example, if your device is part of a corporate environment, it may still recognize that it is under management upon rebooting, and you will need to follow the organization’s protocols to reestablish access.
How do I back up my data before performing a hard reset?
You can back up your data on your Samsung A21s through various methods. The simplest way is to use Samsung’s Smart Switch application, which allows you to back up your files, photos, contacts, and settings to a computer or cloud storage. Additionally, you can manually back up specific data types such as photos and videos by transferring them to external storage or a different device.
For cloud-based backups, make sure you have your Google Account synced on the device. You can back up your app data, contacts, and settings through the Google Drive backup option available in your device’s settings. Ensure everything you wish to retain is backed up before proceeding with a hard reset to avoid loss of important information.
What are the steps to perform a hard reset on the Samsung A21s?
To perform a hard reset on your Samsung A21s, first, navigate to the Settings menu, then go to “General Management.” Here, select “Reset” and choose “Factory Data Reset.” You will see a summary of the data that will be deleted. Confirm by tapping on “Reset” and, if prompted, enter your PIN, password, or pattern to proceed.
Alternatively, you can also perform a hard reset using hardware buttons. Turn off your device, and then press and hold the Volume Up and Power buttons simultaneously until the Samsung logo appears. Once the recovery menu appears, use the Volume buttons to navigate to “Wipe data/factory reset” and confirm your selection by pressing the Power button. After the reset has been completed, choose “Reboot system now” to restart your device.
What should I do if my Samsung A21s is locked and I cannot access the settings menu?
If your Samsung A21s is locked and you cannot access the settings to perform a hard reset through the menu, you can use the hardware button method instead. Begin by powering off your device completely. Then, press and hold the Volume Up and Power buttons together until you see the Samsung logo. This will take you to the recovery mode, where you can perform a factory reset without needing to access the settings.
In recovery mode, use the Volume buttons to navigate to “Wipe data/factory reset” and select it with the Power button. Confirm your choice and proceed. Once the reset is complete, choose “Reboot system now.” This process should help you regain access to your device, but keep in mind that all your data will be erased.
Is there any risk associated with performing a hard reset on my Samsung A21s?
Yes, there are some risks associated with performing a hard reset on your Samsung A21s. The most significant risk is data loss. A hard reset will erase all user data, including contacts, messages, photos, and apps, if not backed up properly. Therefore, it’s crucial to ensure that you have backed up all important information before you initiate the reset.
Additionally, if your device has a Knox security feature enabled and you are unable to access your Samsung account or associated accounts after the reset, you may face challenges in accessing your data or using certain features on your device. Therefore, it is advisable to fully understand the implications of a hard reset, including potential data loss and security restrictions, before proceeding.
