What is Soft Reset ?
This is an easy method and it involves soft resetting the phone to kill unnecessary background processes, temporary cache and it also clears the RAM of your Samsung A21. This process involves rebooting your phone to achieve the end result.
It is very important that you need to take a backup of your data before performing the following two steps
What is Factory Hard Reset ?
- This method wipes out all the settings and all the data on your Samsung A21 and it restores all factory settings to make a near new device.
- This method is useful when you experience bugs, sluggish performance and other software-related issues on your Samsung A21.
- The most important thing to use this step is when you forgot your pattern/PIN/pass code of your phone and need to bypass it
What is Hard Reset ?
- This hard reset method can be used to erase all the information on your Samsung A21. Typically, people use this method when they want to intentionally wipe personal data on their phones before giving it to someone.
Soft Reset is the least risky of all the three methods as it doesn’t necessarily delete any data from the device.
But the other two methods involve data loss and the process is also not very easy for newbies.
So, after all the information shared, the onus is on you to choose which the best process is for you and what you would do
Now, let’s not waste one more moment of your crucial time and get an understanding about the prerequisites you need to remember before starting the process to reset Samsung A21.
While resetting an Android phone, you need to go through some most required prerequisites.
Create a backup of your data
- Backup creation is the most significant thing you need to consider before resetting your Android phone.
- No one can endure losing all his data, and because the Android phone reset process takes away all your data to restart your phone initially, its important to backup your data.
- So before going on, take a complete backup of your data, including your contacts, videos, pictures, and all other things.
Unlink all the Google Accounts
- You must be thinking why unlinking or deleting Google accounts is mandated before resetting an Android phone, right?
- Yeah, it’s real, and you can also lose access to your phone if you aren’t careful with this prerequisite.
- Don’t get agitated, and just unlink all your Google accounts from your phone before resetting it.
- Primarily, Google secures your smartphone by checking your identity after resetting the phone.
- It’s not that tough if you remember your Google account ID and Password, but if you’re unaware, you must unlink your Google account before resetting your Android phone.
Charge your smartphone
- Lastly, Charging the phone is also equally significant as the above prerequisites.
- You won’t ever want to make your phone bricked, but you will unintentionally do that if your phone automatically gets switched off during the resetting process.
Hence, it would be best to charge your phone at least 40% before initializing the process to Reset Android phone.
Disclaimer – Please be careful about all your data before resetting your phone. At last, all the above methods, except Soft Reset, would clear the complete data from your Android phone.
Enable USB Debugging (Only while using Android SDK method – mentioned at the end of the article)
You would only need to enable USB Debugging if you’re going for Method 4 below or simply resetting your phone via Android SDK Tools.
Remember, it would be the exception for the first three methods because none of them require enabling USB Debugging.
- Firstly, open the Settings app on your phone.
- Afterwards, click the About Phone tab.
- Now, search the Build Number and click it repeatedly 7 times.
- You would now get prompted with a notification, saying You’re now a developer.
- Now, get back to the Settings app menu and open the Developer Options. (In Realme phones, you would get Developer Options in the Additional Settings section.)
- Finally, find the USB Debugging option, click, and toggle it to enable USB Debugging.
