Let's take a look at how to format your Samsung phone yourself.

Ways to Completely Clean Samsung

In all phones of the Samsung Galaxy line, the procedure for resetting the system to the factory parameters is provided by the developers, so you do not have to look for and install additional software on the gadget to perform formatting.

There are several ways to format Samsung Galaxy S3, S4 or another smartphone model:

Through device settings. It is the easiest and fastest cleaning method. It is used when the mobile device is turned on (in working condition) and the user has the opportunity to use its menu.
By service combination. Used when the operating system on the Galaxy starts up, however you only have access to the numeric keypad.
Via . Allows you to restore the phone's performance and return to its original settings, even if it is impossible to load the operating system (for example, Samsung hangs on the welcome screen).

It should be noted that a hard reset involves removing all installed applications, notes, text messages, contacts and other user data from the smartphone. Therefore, it is recommended to make a backup of Samsung Galaxy before starting formatting. You can create an Android backup through the Samsung Kies program, Google cloud storage, Titanium Backup program, or in another way.

If the purpose of completely cleaning the phone is to sell it, then before a hard reset you will additionally need to unlink the mobile device from your Google account. If this is not done, then the formatted gadget, when first turned on, will ask for a username and password from the account to which it was previously linked.

To sign out of your Google account, you need to:

After completing all the preparatory activities, you can proceed directly to formatting.

Performing a hard reset through the Samsung settings

The process of formatting a Samsung Galaxy S4 phone or any other model from the Galaxy line will look like this:

Open the device settings through the standard menu by clicking on the gear icon.
Enter the "General Settings" tab. If your gadget does not have such an item, select "Back up and reset" or "Privacy". The name of the required section depends on the model of the mobile device.
Go to "Reset data", and then activate the cleaning procedure by tapping "Delete all" or "Reset".

After restarting the smartphone, only those programs and data that were preinstalled by the manufacturer will remain on it.

Samsung cleaning with service combination

Any smartphone based on Android OS has a special digital-symphonic combination, thanks to which the user can restore the factory settings on the device in a few clicks.

To format Samsung Galaxy using the touch keyboard, you need to:

Enter screen unlock or dialing mode.
Enter the sequence * 2767 * 2878 # or * 2767 * 3855 #.

The first combination allows you to clear the phone without deleting numbers from the phone book and user files. The second set completely erases all data and programs from the smartphone.

Every owner of a modern phone or smartphone based on the Android OS is faced with the problem of "cluttering" the device with various games, applications and other "mobile garbage", which terribly slows down the system. It becomes simply impossible to work with such a technique, therefore it is advisable to carry out formatting. Below we will tell you how to do it manually without the help of paid technical support.

How to clear phone memory

Formatting is a complete cleaning of memory and resetting its settings to factory defaults. In fact, after this operation, you will receive a completely "clean" phone, as if it had just been brought from the manufacturer's warehouse. The only difference is that you can save your personal data, such as your address book, music and photos, before formatting.

It is not so difficult to carry out a "general" cleaning in a phone or smartphone based on the Android OS, especially since we have prepared detailed step-by-step instructions. If you want to keep your data, be sure to back it up or back up. Otherwise, they will be erased along with unnecessary applications and long-forgotten games. To make a backup, transfer the data you need to a removable SD-flash drive and do not forget to remove it before starting the operation! You can also use the "Backup" function.

If the device starts working very slowly, shuts down spontaneously or freezes, then it's time to start formatting it. Thorough cleaning of conventional mobile phones was practiced long before the invention of smartphones with touch screens and it consisted in the introduction of special codes. Each code is unique and developed individually for a particular model of a mobile device. You can find out the combinations of numbers for formatting the phone on specialized forums.

It should always be remembered that personal intervention in the operation of mobile equipment is a personal decision of the owner of the phone, for the consequences of which no one is responsible except him. If you are not sure of your capabilities, it is better to leave the job to an experienced craftsman.
