Program preparation

It should be understood that resetting the Samsung Galaxy S3 to the factory settings is a complete deletion of all smartphone information. After this operation, your device will become the one you took it from the store - empty. It is for this reason that it is simply necessary to carry out a series of procedures to move or copy all available contacts, photos, and other equally important files. Where to? There are several options:

By the way, do not forget to check the name of your Google account, as it will also be deleted. Remember that after the Samsung Galaxy S3 mini is reset, nothing will remain on the device and will not be subject to recovery (except that you will move it from the phone’s memory in advance).

Simple reset

The most basic option is to reset the Samsung Galaxy S3 to the factory settings through the settings. To do this, in the "Settings" you need to enter the section "Archiving and reset", where, in fact, carry out a reset, as seen in the image.

Depending on the system, the second item can be found in the "Options" or "General tabs". This simple method is suitable when the decision to reset was not caused by a strong malfunction, but as a preventative measure or elimination of minor system problems.

Reset through recovery

First you need to completely turn off the smartphone. Some devices, due to a powerful software malfunction, require drastic measures - holding the shutdown button for 10 seconds or completely removing the battery. The second is best avoided.

You can get into the recovery on the Samsung Galaxy S 3 by pressing three keys - turning on, increasing the volume and going home. When the Samsung logo appears, you only need to release the power button. The rest should remain clamped. As a result, a window appears with a number of inscriptions in English, and in order to reset to the factory settings of the Samsung Galaxy S3 to the end, you must first select the “wipe data and cache” volume keys. In order to select, you need to press the power key, with it to confirm your choice.

After some waiting, a new window will appear. In it, it is already necessary to select “reboot systems of science” and, as before, use the power button to confirm your choice.

As a result, the Samsung Galaxy S 3 smartphone will turn on as if you had just taken it from the store and now you just need to configure it. It will not have any passwords, SMS messages, your favorite applications, and so on.

No matter how complicated the methods described above may seem, the process of resetting your smartphone to the factory settings does not take so much time.

In some cases, after the reset button was used, the problem did not resolve. If such a fate befalls your smartphone, immediately bring it to a service center, where specialists with the help of special equipment and programs will start your device and make it a complete reset.

Moreover, a full reset does not always in principle solve the problems of the device. In more than half of cases, it is possible to ensure the normal operation of the device only by flashing the phone. For this, again, you need to contact the specialists. Remember that self-repair can only aggravate the situation, and your device will become nothing more than a heap of metal and plastic, the place of which is in the bin.
