Now we will try to deal with the question of what the term factory reset means and how to carry out this procedure on our smartphone. The article will be useful to Android users who have encountered problems in the OS.
What are you talking about?
Factory reset is a hardware reset of all settings and returning the device to its original "factory" state. The final version of the term has not yet taken root, so this procedure of “hard reset” is called differently by different sources, you can find similar terms in meaning: hard reset, Cold Boot, Master Reset.
So, having factory reset Android, we will achieve a device reboot, thanks to which all the factory settings of the system are restored, and all information of the operating system disappears: SMS, contacts, installed programs. Note that information deleted in this way cannot be renewed. At the same time, the data that is on the memory card, as well as the SIM card, is not deleted.
Without asking
There is such a thing as a spontaneous factory reset. It occurs due to a conflict that is caused by incorrect interaction of applications installed on one device. Another cause of this error may be a system failure.
What is the indicated reboot for?
In modern devices based on Android there are many applications that can sometimes cause a crash. However, each smartphone has an internal independent area that stores system files. If your operating system began to "behave badly" or you configured something incorrectly (for example, you installed a graphic key while forgetting the pattern), the manufacturer provided a special key combination in advance, when using which the software platform of the smartphone will return to its original state.

To make a factory reset, you first need to go to “System recovery”, for this purpose you need to find out the same key combination set by the manufacturer. So we already got into the menu, where many interesting lines are displayed. Using the volume buttons, go down to wipe data / factory reset. We activate the function by applying the Power or Home button. A new menu appears, in which there will be many lines of “NO”, and somewhere in the middle is the line “Yes”. You should go down and activate it.
As a result of all the above actions, the phone will reboot, and then return to the original settings. If you are not confident in your abilities, consult a specialist.
