A complete reset of Android settings to factory defaults is called a hard reset. It is recommended to do it if the smartphone is not stable (often freezes, buggy, etc.). It can be done in three different ways, each of which will now be discussed. Before starting a hard reset, do not forget to do backup all data.

Do full copy all smartphone data can be using the program.

Programmatic way to reset Android

After that, a warning will be shown about deleting all existing data, and at the bottom - a confirmation button "Reset phone settings".

You need to confirm the selected action by pressing the "Erase all" button.

Resetting Android settings when the smartphone is not responding

Sometimes there are times when the gadget does not respond to any commands. In this case, the third method of resetting the settings may come in handy. When turning on Android, simultaneously hold down three buttons: "Power", "Home" and "Volume Down". This combination should be held until the “ ” mode appears. In it, select the “Wipe” section (which means a complete reset of the settings) and confirm your choice by pressing the “Home” button.

After a hard reset, you may be tempted to restore Android from a backup. However, this should be done with great care - after all, perhaps the problem that caused the problem lay in the previous settings or in one of the installed applications. Therefore, it is better not to take risks, but to set up your smartphone as new by entering your google account details. After that contacts mail letters etc. will be synced with your smartphone. The necessary applications can be installed independently from the Play Market.

Fans of alternative firmware for Android should remember that a hard reset does not affect the areas that store installed additional firmware. This means that any mods and software changes operating system will not be deleted from the phone's memory. This fact should be taken into account if full recovery performed, for example, in order to return the gadget under warranty.

In addition, a full reset does not affect the contents of the memory card. You will have to remove information from it yourself. However, remember that any deletion with the "Delete" command is easily reversible, and in case of confidential data, it is better to take care of the card additionally.

Slow operation, app freezes or sudden shutdown of the smartphone is a serious problem. To solve it, you need to know how to return or reset the settings on Android to factory settings, in which, most often, the reason for the incorrect functioning of the gadget lies.

Resetting settings on Android is an operation during which absolutely all data is erased: photos, cache, videos, RAM, clipboard, applications and various widgets downloaded by the owner himself after buying a smartphone.

When you may need to factory reset your Android phone:

• If the owner is going to sell the gadget. In this case, all confidential information, which must not fall into the hands of unauthorized persons.
• When the device "hangs" and is buggy on the simplest operations. This is usually due to clogging random access memory, and it is easiest to clean it in this way.
• A virus has entered the system, and the antivirus program cannot remove it on its own. Only a hard reset or resetting the settings to those provided by the factory with a full formatting of the memory will help here.

How to find Hard reset on your phone

There are several ways to use the "Reset" function on Android:

• Through the normal menu. Make hard factory reset in this way, the easiest way, besides, the process will take a minimum of time and does not require special knowledge and skills.
• Using service codes. In most cases, they are universal and suitable with equal success for both Samsung and HTC, LG, Sony and other manufacturers of smartphones and tablets.
• By pressing hot keys in a certain combination. Suitable for devices of any brand.
• Using a computer (suitable for hard reset advanced users only).

Before the procedure, it is recommended that you read the instructions for each method: it will help you understand how best to return the gadget to the factory settings on the Android platform and avoid fatal errors, because of them the entire system may completely stop working.

Preparing to reset

In order not to lose all data and make the functioning of the mobile phone optimal after a rollback, it is recommended to carry out preliminary preparation before the procedure:

1. Copy important photos, videos and other essential information to a flash drive, PC or cloud. If this is not done, all data will be lost, and the master will have to pay a lot of money for recovery.
2. Fully charge the device. In the process, it will be discharged if there is not enough charge, and interrupting the procedure will lead to bad consequences, up to the inability to start the OS. If a hard reset is performed through a computer, the amount of charge does not matter, because the phone is connected to the PC via a cord and is charged from it.
3. Delete Google account if the smartphone is running Android 5.1 or higher. The fact is that the company has introduced a new security policy, according to which, after the rollback of the operating system, users need to enter the data of the last account. Without this, it will be impossible to turn on the device, and you will have to contact service centers that take up work only if there are supporting documents for the gadget.

The above actions are relevant for all mobile devices: for example, on Samsung and other brands, Google binding is required, although the owner may not use it.

Backup

It is possible to identify several simple ways, allowing you to backup before resetting to factory settings on Android:

• Using a Google account.
• Via PC and using ADB tools.
• With the help of custom Racovery.
• Through the DataSync program.

The best option is to backup through an account, because full synchronization takes place in it, as a result of which the user gets easy access to backups. How it's done:

1. Go to "Personal" and "Accounts".
2. After selecting your account, check the boxes next to all fields.
3. We return to the previous step again, click on "backup" and "reset", select data archiving and automatic recovery. We produce full check working account and go to the synchronization menu, where we click on "Synchronize".
4. We enter the account. Click on reset to roll back to the previous version.

This option is only suitable for those who remember all the account information (login and password). It will be needed later after the rollback and reboot of the system, in otherwise the device cannot be used.

As a result of synchronization and backup in Google, after turning on the device will automatically download all the data from the "account".

To perform the operation through ADB RUN, you will need a PC and a cord from a smartphone, which must be inserted into the USB connector. The process consists of several stages:

If custom "Recovery" is installed in the OS, full copy firmware, rather than creating a backup. What needs to be done:

1. Enter Recovery, click on "Backup and restore".
2. Select "Backup" to copy, then "Restore" to restore.

Another copying option is to use the DataSync application. It is suitable for users who only need to transfer data from other applications. If you need to create archive copies of them, you will not be able to do this using DataSync.
