Step 1: English Answer

A factory reset restores your phone to its original state, as if you had just taken it out of the box. It wipes all of your data, including your apps, settings, and personal files. This can be a helpful way to troubleshoot problems with your phone, or to prepare it for sale or trade-in.

Here's what a factory reset does to your phone:

* Deletes all of your apps and data. This includes all of your downloaded apps, as well as any data associated with those apps, such as your account information, game progress, and saved files.
* **Restores your phone's settings to their default values.** This includes your display settings, sound settings, and network settings.
* Erases all of your personal files. This includes your photos, videos, music, and documents.
* **Reinstalls the original operating system that came with your phone.** This is the same operating system that was on your phone when you first took it out of the box.

It is important to note that a factory reset is a permanent process. Once you have performed a factory reset, there is no way to recover your deleted data. For this reason, it is important to back up your data before performing a factory reset.
