How to Format OPPO F21s Pro 4G

Each phone can store a fairly limited set of data. Of course, there are devices with a memory capacity of 1 TB or more, but most people have phones that store 32, 64, or 128 GB. If you actively use your smartphone for photo and video shooting, the memory will quickly run out, and the device will need to be cleaned. One of the most effective ways to clean up memory — is to format OPPO F21s Pro 4G.

What is formatting and in what cases should it be done

In simple terms, «format the phone» means to erase all data from the hard drive. Speaking in a more complex language, each hard disk contains a certain number of blocks into which information is written. The user's interaction with this information is through a pad — the file system. On Windows operating systems, this is NTFS, on Linux — ext4 or btrfs, and on Android and iOS — Fat32.

During formatting, it is the file system that is erased from the disk, which leads to the automatic deletion of all data, since access to them is lost. At the same time, it is still possible to restore some data, although this will require special software that can restore individual blocks. It is also worth understanding that new information will be recorded in the old blocks. That is, the more device memory you have taken up after formatting, the less chance there is to restore old data.

So, let's fix the information. Formatting — the complete removal of data from the hard disk by reinstalling the file system. You should use this cleaning method only in extreme cases:

• Do you want to set up a phone «from scratch»;
• Your device is infected with a virus, and the only way to get rid of it — is to delete all files from the device;
• There is too much «garbage» in the phone, which takes up all the memory.

How to perform formatting

Important! Before formatting, transfer all significant data somewhere — passwords, photos, videos, notes, documents, and so on. After formatting, your phone will become a «blank slate», you will have to reinstall all applications, log in to accounts, and so on.

For formatting OPPO F21s Pro 4G:

1. Open the «Settings».

2. «System»
3. «Reset settings».
4. «Delete all data (reset to factory settings)».
5. Confirm the data reset (you will be shown most of the data that will be reset).
6. Enter the PIN code and confirm the data reset again.
