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, after a while the Android OS device is no longer as powerful as when purchased.

    What should you do if your smartphone starts to work poorly and doesn’t display the same information? good performance like before? If you have this problem, resetting your settings on Android or otherwise called Hard Reset will help you. But how to do this?

But how to reset an android to factory settings or how to reset an android? We'll find out now.

    Hard reset or the data reset process is named for a reason - after the process is completed, all user data will be deleted from the device. The data includes: all the applications you have installed, contacts on the phone itself, as well as all account data. But all data on the memory card will remain unaffected. To delete data from a memory card, you must 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 downloaded 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 it was when it was purchased. The very same Android system will remain the same and is often not included in the reset data.

    Why do you need to reset your smartphone:

    • A device on an Android system must be prepared for sale or the purchased device must be cleared of old data;
    • Troubleshooting device performance issues. Usually, after using a smartphone for a long time, unnecessary files accumulate in it, which affect the characteristics of the smartphone, as well as its battery and overall service life;
    • You can solve the problem with Google software, in particular - Google Play Market;
    • Unlocking your smartphone if you find an unsolvable problem software problem or forgot the PIN code to unlock the device.

    What to do before resetting settings

    1. Do backup copy data. A data backup or Backup data is the saving of downloaded smartphone data on other storage media. That is, save your media files, applications, user data. This can usually be done immediately before performing a factory reset using Google services. But you can do this yourself using a flash drive or memory card.
    2. The device must be charged at least 70%. Some smartphones cannot be reset when the battery is low, and if your smartphone dies and turns off during the data reset process, this may lead to errors that only a technician can fix.
    3. If you have an Android system 5.1 and higher, then you need to remove all Google data through the setup menu. The fact is that after resetting the device, you need to enter your account information again, and if the old ones are not deleted, the smartphone will stop working, and restoration is only possible in service center with documents confirming the purchase of the device.

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

    • Through a special android menu– recovery;
    • In the smartphone settings;
    • Through a special code in the dialing menu, which is located in the Contacts application;
    • Using a special button or hole located in the Android smartphone.

    How to reset your smartphone via the recovery menu

    This method is for advanced Android users whose device is locked, has an incorrect PIN code/pattern and does not have access to the settings menu, in other words, it’s just a brick.

    To access the recovery menu, turn off the device completely (you can remove the battery and insert it back). Next, you need to hold down a certain key combination. It’s also worth knowing what’s on different devices– 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;

    Home(home button) – used to enter the recovery menu;

    After executing one of the presented commands, your smartphone will enter the Recovery menu:

    In most versions of recovery, moving through the menu is done using the keys of the smartphone itself:

    • Volume up button – move up;
    • Volume down button – move down;
    • Power button – open the selected menu item;

    But there are also other versions of recovery where touch navigation through the menu is available.

    Let's move on to the process of clearing smartphone data:

    1. Go to the menu item “wipe data / factory reset” or “Clear eMMC” / “Clear Flash”.
    2. Next, agree with all points (yes) and click “delete all user data”
    3. Once finished, restart your device by selecting " Reboot System Now"

    The process of resetting data through the recovery menu is the same for all Android devices; the only differences may arise in the names of the menu items and the recovery version.

    This method is suitable for you if you have the opportunity to log into the smartphone itself, in the settings menu:

    Go to 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 Samsung smartphones: Archiving and Resetting - Archiving and Resetting - or Confidentiality;
    • On Huawei smartphones: Advanced settings - Recovery and reset;

    Next, you will be warned about clearing all information (accounts, contacts, etc.) and also that this may be dangerous for the device. At the very bottom, look for the “Erase all data” item. There will be another similar warning - we agree and clean our device.

    Often this type of cleaning is not much different in different Android devices, because... this cleaning provided by the operating system itself.

    Resetting Android device data via dialing or "secret code"

    One of the most simple ways to reset android data devices. You don't need to learn special combinations or delve into device settings. You just need the “phone” or “contacts” application, where you need to enter a special code to reset the data:

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

    But it is worth considering the fact that each Android device can use its own code installed by the manufacturer. Therefore, you should find out the exact code on the Internet before starting the data cleaning procedure.

    After you have entered one of these codes, press the call button and the process of clearing all data from the device will begin.

    Resetting an Android device to factory settings through a special separate button or hole

    Older Android devices and some new ones have a reset button on the device itself. It is made in the form of a very small hole and to activate it you need a needle or toothpick.

    The main thing is not to confuse the data reset hole with the microphone hole. After activating the button, the device will return to factory settings, and all user data will be deleted.

    Performing a data reset on an Android device is a fairly simple task, the main thing is to do everything according to the instructions and select the right way for your smartphone. Only if you follow the instructions and follow all the rules for using the Android system, you will be able to do everything as it should.

    But if you are afraid or do not work well with computers and smartphones, then it is better to turn to a specialist. He knows how to do all these procedures and will definitely not make mistakes.

    Very often the Android device gets clogged unnecessary files, begins to slow down or stops responding to commands altogether. In this case, a full system reset to factory settings may help. In addition, a “hard reset” will help if you have forgotten your gadget and cannot turn it on.

    After the so-called “reboot”, you will lose all the data that you stored in the smartphone’s memory: phone numbers, applications, SMS messages, account data and calendar entries. In short, the phone will be as good as new. So as not to lose necessary information, create a backup copy of your data. Transfer them to an SD card, save them in the cloud, or download them to your computer.

    If you can turn on your gadget, it is easier to reset the settings through the device menu or using special codes provided by manufacturers. If your smartphone freezes or does not turn on at all, you will have to use the Recovery menu or find a button to reset the settings.

    Resetting settings through the gadget menu

    This is the simplest factory reset method and does not require memorizing complex codes or key combinations. For latest versions Android OS "hard reset" consists of the following steps:

    • Go to the main menu.
    • Find the "Settings" section.
    • In Settings, select Backup & Reset or Backup & Reset. The name of the desired item may sound different (depending on the brand or model of the device).

    To return the device to factory settings, you will need the “Reset” section, the “Reset settings” item.

    Android will warn you that after a reset, the phone will return to factory settings and default settings, and all user personal data will be deleted.

    If you have backed up the necessary data and are ready to reboot Android, click on “Reset settings”. Depending on the device model on the desired button there may also be the words “Erase everything” or “Reset phone”.

    The data deletion process will begin, and after that the device will reboot.

    Resetting settings using service codes

    Entering the service code

    Perhaps this is the most quick way reset settings to factory defaults. For this purpose, Android provides special service combinations– codes that must be entered into “Phone” in dialing mode.

    Each manufacturing company flashes its gadgets differently, so before using codes to reset settings, you should find the desired combination for your model. Because Android version updated all the time, then service codes may change. It is best to check with the manufacturer of your device.

    Example of codes that are suitable for resetting Samsung gadgets:

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

    After entering the code, all user information will be deleted from the device and it will return to factory settings.

    Resetting settings in the Recovery menu

    If your gadget does not turn on or is stuck on the system boot screen, you can return it to factory settings using the Recovery menu. It is called by pressing special combination keys

    U various models devices it could be different combinations keys The most common of them: “Volume down” plus “turn on” button. The combination can also be “turn on” + “home” + “volume up” or “volume up” + “home”. To enter the Recovery menu, press the keys simultaneously and hold them for about 5 seconds.


    Moving between menu items is done using the volume up/down buttons.” To confirm the selection, use the “turn on” or “home” button. However, sometimes the sensor works in Recovery: then everything happens as in the regular smartphone menu.

    To reset settings to factory defaults:

    • Select “Clear eMMC”. It may also be called "wipe data/factory reset" or "Clear Flash".
    • To reset the settings, click “yes - delete all user data”.
    • To finish, select "Reboot System"

    Use this method This is possible not only when you have problems turning on your smartphone. If you want to use it for a working device, first turn it off, and when all the buttons and the screen go out, use the combination necessary for your gadget.

    Like any other operating system, Android may not always work the way you want it to. For example, when starting the simple application The smartphone starts to slow down or freeze. Often something similar happens even with normal incoming call. Many owners of smartphones and tablets based on Android OS are upset, and some even suggest purchasing a new device. Don't rush! Most problems can be resolved with a factory reset. This function is present in this operating system.

    On English function called Hard Reset, which can be translated as “ hard reboot" In fact, the system is rebooted, which restores the initial factory settings. In addition, all information that was added by the user is deleted, including applications, SMS messages, contacts, video and audio clips, etc. Therefore, before performing a hard reboot, it is recommended to save the data that you will need later.

    Information is deleted only from the phone's memory. Those files that are on the memory card, if present, will not be deleted. However, you can remove them yourself from the menu using a soft reset.

    So, if you decided to do a Hard Reset and saved all the important data that you needed (for example, using backup), then we can begin the procedure itself.

    Method one

    I will show an example on "naked". If you are using a smartphone or tablet with add-ons, the menu may be slightly modified, although the procedure itself will not change. Let's go.

    We look for the “Settings” application on the desktop. If it is missing, find it in the "Application List". I have “Settings” on the main screen.

    The menu opened. Now you need to find the “Backup and Reset” section.

    We go and select the section “Return to factory settings” - “Reset settings”. Here you can configure backup your data.

    You will see a kind of reminder that says that all data will be deleted from the internal memory of the device, including settings, applications, and even added Google account(the account itself, of course, will not be deleted, you’ll just have to re-enter your login and password next time). Click on the “Reset phone settings” button. If you also need to clear the memory card, check the box next to “Clear card memory”.

    The system asks again whether to reset? When you're ready, click Erase Everything. The device will reboot. Most likely, the reboot will take a little longer than your gadget usually loads - this is quite normal, do not panic.

    Method two

    You can try to use even more simple method. All you need to do is dial *2767*3855# and send a call. Afterwards a Hard Reset will automatically occur.

    However, I do not recommend using this method for the simple reason that, according to reviews, on different devices this set digits can perform different functions. So, on some devices it allegedly changes the IMEI. I find it difficult to say how true this is, and therefore I advise you to be as careful as possible.

    Method three

    This is the so-called hard reset. You should only use it if your device does not turn on. If it works, use the first method.

    So, your device does not turn on, just in case, remove the memory card from it, if there is one. To log into Android system recovery(the menu we have to work with), you need to press the buttons on the device body in a certain order. The problem is that the combination of buttons may vary from manufacturer to manufacturer. I decided to show you an example on a device from Samsung, one of the leaders Russian market mobile devices.

    Since the device is already turned off and will not turn on, we immediately proceed to active actions.

    • Press and hold the Volume Up key, the Power button, and the Home button.
    • Keep them pressed until a green robot appears or the menu starts to load.
    • Using the volume keys, select wipe data/factory reset and confirm it with the device on/off button.
    • In the menu that opens, select Yes - delete all user data, after which settings and files will begin to be reset and deleted.
    • Then click select Reboot now and the device will reboot. You will receive a device with a completely clean operating system.

    Regarding restoring settings

    After the user makes a Hard Reset, he will probably want to use a backup to get back all his settings, files and applications. Is it worth doing? The question is controversial.

    The problem is this: if your device did not work properly, for example, it froze or slowed down during operation, then it is quite possible that the cause was some application or certain settings. If you restore the backup, then there is a high probability that your device will work exactly the same as before full reset settings. Therefore, it makes sense to restore a backup only if you are sure that the problem is definitely not in the previous settings or applications.

    Contacts can be transferred manually, just like necessary documents, and applications can be downloaded from . In my opinion, this is the most optimal solution.

    Custom firmware

    Regarding custom firmware, then they are restored in exactly the same way, there is no need to reinvent the wheel. The main thing is to remember that if you need to return the phone under warranty, you will first need to bring it to life if it does not turn on (use the third method), and then reflash it to factory firmware. And remove root rights if they were installed.
