Also, if you have forgotten the pattern lock or password of your Samsung M21s, then don’t worry, I have given below two unlock methods by which you can unlock your phone, all you have to do is follow the complete guide.
What Is Reset?
Factory reset deletes all stored data on your Galaxy M21s and reverts it back to the default system settings. In other words, after doing a factory reset, it returns the device as if you bought the device for the first time.
It will clear whatever data is stored on your Galaxy M21s like contacts, photos, apps, videos, your application cache data.
Don’t worry, this won’t remove the device’s operating system (iOS, Android), but will return apps and settings to their original set.
Also, since resetting doesn’t harm your Galaxy M21s, you should do it at least once every six months.
Why would you want to reset your device?
The most common reason would be if you want to give away or sell your device to someone else.
Because you would absolutely not want any of your personal information to remain on the device.
Other reasons include:
- To clear your phone’s memory space,
- Fix a device slowing down or hanging issue.
- To fix phone constantly freezing issue.
- Speed up the performance of your phone.
Benefits of Resetting Samsung Galaxy M21s
By resetting your Samsung Galaxy M21s, all junk files are deleted from your phone, and your Galaxy M21s is fully cleaned, so it does not even hang and work well.
Also, nowadays a lot of pop up ads are coming in the phone due to some virus. If you reset your phone, then you can get rid of unnecessary popup ads.
Using this method, your Galaxy M21s will be completely clean and like new condition, as well as all your settings will be back to default.
Detriment of Resetting Samsung Galaxy M21s
If you reset your Galaxy M21s, you will lose all your data (contacts, images, videos, installed applications). So before resetting your phone, you must keep the backup of your phone so that you can recover all your data later.
Before you reset your phone:
- The reset process requires a minimum of 50% battery, so fully charge your Samsung M21s, if your phone battery is low and you will perform the reset process then you may get stuck in the middle of this reset process.
- Make sure to Take Complete Backup of your Android Phone.
