How to remove all settings on android. How to restore factory "Android" settings

Good afternoon!

No matter how "smart" the Android system is, all the same, it happens to it from such moments when you have to resort to resetting the settings (it is also called Hard Reset). For example, this often happens when there are problems with Wi-Fi, Bluetooth, with the "overload" of the phone's memory, when inexplicable brakes and freezes appear, etc.

You can also face this task if you suddenly decide to sell a phone (after all, you would not want a stranger to see your personal correspondence ?!).

I want to note right away that in the process of resetting from the device's memory all applications and games, all SMS messages and contacts, mail accounts, etc. will be deleted. In general, the phone / tablet will be completely with the factory settings (approximately the same as it was upon purchase).

Note! If you have an SD card installed, then all data on it will remain intact * (at least this was the case with the devices I worked with)! Those. it is the device memory that is cleared!

Therefore, if you have the necessary contacts, photos, videos and files - before resetting, save them to HDD PC or cloud storage (for example).

Actually, now you can get down to business ...

Method 1: through system settings

Perhaps this is the most obvious and simplest of all methods. Suitable in any cases when you can safely enter the Android settings (I know that this is not always possible, therefore, if you have a more global problem, see the following paragraphs of the article).

And so, you need to open the "Restore and Reset" section in the Android settings. See example below.

Then click on the button "Reset phone settings" ... Please note that the system will also warn you that data will be deleted from Google account, all applications and data in them, music, photos, videos, etc.

Actually, in this way, there is nothing more to comment on ...

Method 2: via Recovery mode (or Factory mode)

If your device is frozen, there is a problem with entering the settings menu - in this case, the reset can be done through the special. menu "Recovery mode / Factory mode".

To call it:

Method 3: using service codes

If you know the specials. codes, then you can seriously change the settings of the Android system. There are codes for resetting the settings (i.e. going to the factory state of the device).

Note! The codes presented below may not apply to all devices (especially to new ones, which are constantly being changed ...). Therefore, all codes below are presented for your reference (I am not responsible for your device and software).

Codes are entered quite simply. You must switch to dialing mode and enter one of the following options:

*2767*3855#
*#*#7378423#*#*
*#*#7780#*#

Entering the service code (Do not play with the codes just like that - you can easily erase all the data ...)

Method 4: how to delete data from phone / tablet if it was lost

Unfortunately, almost everyone gets into trouble in life. One of these is the loss of a phone / tablet (I am not even considering the reason now: was it stolen, or simply dropped, or something else ...). The main thing is that you do not have it in your hands, but it contains a lot of confidential data (and that you would like to delete as soon as possible).

In this case, you need to log into your account from your computer to;
Next install the application (direct link to Google play) ... Note that applications can be installed on a smartphone, even if you do not have one at hand.
Then, by going to the application website Find My Device, you can:

erase all data from the device;
call him;
or just block.

Quite often, an Android smartphone has various problems and errors in the system. And this is not surprising, because the system is simple, with free access, but at the same time it is easily vulnerable to viruses and malware. Because of this, the device on the Android OS after a while is no longer as powerful as when it was purchased.

What to do if the smartphone starts to work poorly and does not produce as good performance as before? With such a problem, resetting the settings to the android will help you, or in another way is called - Hard Reset. But how to do that? You can take the phone to a service center and pay a lot of money and also spend time, or you can do it all yourself at home. But how to reset android to factory settings or how to reset settings on android? We'll find out now.

Hard reset or the data reset process is named for a reason - after the end of the process, all user data will be deleted from the device. Data includes: all applications you installed, contacts on the phone itself, and all account data. However, all data on the memory card will remain unaffected. To delete data from the memory card, format the memory card itself.

What is Hard Reset / Factory reset or how to reset settings on Android ?

Hard Reset / Factory reset is the deletion of all data that the user uploaded while using the smartphone. That is, photos, music, applications downloaded by the user, account settings and other user data will be deleted - the smartphone will return to the state when it was purchased. The Android system itself will remain the same and are often not included in the reset data.

Why do you need a factory reset on a smartphone:

A device on an android system needs to be prepared for sale or the purchased device must be cleared of old data;
Solve device performance problems. Usually, after using a smartphone for a long time, it accumulates unnecessary files that affect the characteristics of the smartphone, as well as its battery and general term service;
It is possible to solve the problem with Google software, in particular - Google Play Market;
Unlock your smartphone if you find an unsolvable software problem or forget the PIN to unlock the device.

Things to do before factory reset

Back up your data. Data backup or Backup data is saving the downloaded smartphone data on other data carriers. That is, save your media files, applications, user data. This can usually be done immediately before a factory reset using Google services... But you can do it yourself using a USB flash drive or memory card.
The device must be at least 70% charged. Some smartphones cannot reset data when the battery is low, and if your smartphone runs out of power and turns off during the data reset process, it can lead to errors that only the wizard can fix.
If you have android 5.1 or higher system, then you need to delete all Google data through the setup menu. The fact is that after resetting the device, you need to enter your account data again, and if the old ones are not deleted, then the smartphone will stop working, and restoration is possible only in a service center with documents on the purchase of the device.

How to reset Android to factory settings - today there are four most popular and convenient ways to reset smartphone data:

How to reset smartphone data through the recovery menu

This method is for advanced users of the Android system, whose device is locked, the PIN code is incorrect / pattern key and there is no access to the settings menu, in other words - just "brick".

It is also worth knowing what is on different devices ah - different key combinations to enter the recovery menu, take a screenshot, reboot the smartphone, etc. etc.

To control the recovery, use the following buttons on the device itself:

Volume down(volume down) - menu item down;

Volume up(volume up) - menu item up;

Power(device power button) - select a menu item;

We go to the menu item "wipe data / factory reset" or "Clear eMMC" / "Clear Flash".
Next, we agree with all the points (yes) and click "delete all user data"
When finished, restart your device by selecting "Reboot System Now"

The process of resetting data through the recovery menu itself is the same for all android devices, the only differences may arise in the name of the menu items and the recovery version.

This method will suit you if you have the opportunity to enter the smartphone itself, in the setup menu:

We go into the "settings" application in the device itself:

According to the standard, we are looking for the following menu items: Advanced settings - Restore and reset;
Accounts (Personal Data) - Restore and Reset (Backup and Reset)
On smartphones Samsung: Archive and Reset - Archive and Reset - or Confidentiality;
