If a hard reset is performed through a computer, the amount of charge does not matter, as the phone is connected to the PC via a cable and charges from it.
3.- Delete the Google account if the smartphone is based on Android 5.1 or higher. The fact is that the company has introduced a new security policy, according to which, after rolling back the operating system, users must enter the details of their last account.

How to restore Android factory settings?
A user of an Android device is faced with the need to restore factory settings. Sometimes the reason for this is failures and slow device performance, and sometimes restoring factory settings is just preparing the device for sale.
The factory setting is the state in which the smartphone was launched from the factory with the Android OS. You need to understand that factory reset completely removed all user files, apps, photos, videos and contacts from device memory.
Only what is stored on the memory card will be saved, while the internal memory of the device will be completely erased.
There are several ways to restore factory settings on your phone. The most common of them is the Reset button available in the gadget menu. In addition, a special mode is often used that allows the original parameters of the device to return if it does not boot. In addition, it can act through a computer or a numerical combination.
Reset your Android by settings menu
The main rule that the user must comply with: before the configuration established by the manufacturer, the device must be loaded. If it doesn't, after the procedural is complete, it may not start.
The easiest way to reset your phone or tablet to factory settings is with the built-in function of the Android system.
Depending on the brand of the device, the path to the button that activates it may differ.
The procedure is as follows:
1.- Open the configuration menu.
2.- Go to configuration.
3.- Find the tab where the factory reset button is hidden. For example, for Samsung it is "General Settings" and for OnePlus it is "System". On other models, the name "Restore and restart", etc. may appear
4.- Click on "Reset data". Some phones and tablets make it possible not to return to the original state, but also to delete only part of the information. For example, Samsung allows you to reset the settings to the default values or clear the red setting. Therefore, a Reset button is available in your General Settings menu. After clicking on it, the necessary "Reset data" button will appear to go to the initial parameters.
5.- Read the message that appears that the information will be destroyed without the ability to undo the action. Click the button below the notification. It may be called "Reset Device", "Reset Settings", etc. Enter your PIN or pattern.
6.- Confirm your intention to restore the original state of the gadget.
After that, the phone or tablet will start to restart on its own. When it is turned back on, it will only have the manufacturer's settings. User information will disappear.
Reset the system through recovery
This method will be necessary for those whose devices are not working due to failure during update or other software problems. It will also help if a virus is causing the problem.
You must first determine how to activate this mode on the device you are using.
Possible combinations with the

B.- Aparecerá un mensaje en la pantalla en el que debe seleccionar la acción deseada: reiniciar o apagar. Elige el primero.
C.- If everything is done correctly, the screen goes blank and after a few seconds a notification about the start of the Android system appears.
NOTE.- For most smartphones, you need to turn off the device and then fix the indicated buttons simultaneously. For some devices, for example manufactured by Motorola, this function can only be called from bootloader mode.
There may be more complex options. For example, on LG devices, you need to press and hold the combination of the power and volume down keys, release both when the logo appears, and then repeat the action.
The keyboard shortcut depends not only on the manufacturer, but also on the specific model of your phone. Therefore, in some of the devices of this company, it will only be necessary to release the power and the volume control must be continuously maintained. The transition to this mode is made as difficult as possible to avoid the risk of accidentally pressing the required combination.
Restart with keys according to models.
Android can be put into recovery mode using the buttons on the case.

How the factory reset is protected
Devices with Android 5.0 and higher are protected against resetting to original settings. This was done to minimize theft damage. When you return to the manufacturer settings, the previously recorded information is no longer available. However, this information is saved in the gadget. They can be obtained by special programs that scan the internal memory and removable SD card and allow you to extract the data.
The proposed protection boils down to the fact that after resetting the device, the owner will have to enter the username and password of the Google account to which it was linked. If this is not done, the gadget will remain locked. You will not be able to access it and attempt to restore the information stored on it.
So if you go back to the manufacturer's settings before selling the phone or tablet, the user should delete their Google account. Only after that, you can start destroying data and resetting settings.
Reset if your phone cover is removable.
You can also reset the Samsung Galaxy in a different way if your phone's cover is removable.
1.- Turn it off by holding down the Power, Volume Down and Home keys for a few seconds.
2.- Place your fingernail in the hole in the panel and remove the cover of the phone.
3.- Take out the battery from your phone. for
4.- After 1-2 seconds, reinsert and close the panel. for
5.- Turn on the cell phone by pressing the combination of keys used previously to turn off.
Android data is deleted?
When you do a factory reset, the idea is that everything is completely removed, but this is not entirely true. Android removes the addresses of all your data from its memory, so it no longer knows where it is and cannot display it, but it does remain in flash memory. Therefore, someone can use special programs to recover deleted files to get them back.
Let's see how you can avoid this.
Encrypt data on your Android
The first option is to encrypt the data. This feature is already built into Android and requires you to enter a PIN or password each time you unlock the screen. Anyone trying to recover data from their phone will need a special decryption key that they don't have.
The exact path to this feature may vary slightly, but it is usually found in Settings → Security → Encrypt data. But on a Samsung Galaxy, for example, you need to go to the following path "Settings → Lock screen and security → Encrypted data protection". There is also the option to encrypt the SD card, but if you are selling a phone, we recommend that you just take it out.
NOTE.- If after purchasing the phone you already had Android 6.0 Marshmallow or higher installed, then it should be encrypted by default and you can proceed to the next item.
If you do not know which version of Android you have installed, open the menu "Settings → About device → Information about software". Note that by default it will only be encrypted if Android 6.0 Marshmallow from
Overwrite with unnecessary data
If you want to be absolutely sure, you can overwrite the encrypted data with unnecessary data and then perform a factory reset.
Then it will be really impossible to recover your old data. If you want to do this, just download various "junk" on your phone until the storage is full; some videos should work. Then restart again one more time.
You can also overwrite your data, using apps from the Google Play Store, for example iShredder 6. You can fill the free disk space with various "junk", reliably clear the application cache or individual files and folders.
Restart for problematic apps on Android?
Some apps that you download can cause problems with your phone. Follow the steps below if your phone has any of these problems:
1.- The phone restarts itself.
2.- It does not respond when starting.
3.- Failure of the phone's Apps.
4.- The phone runs slowly.
Step 1: Reboot in Safe Mode. Important: Safe mode removes some widgets from the Home screen. If you use widgets, take a screenshot to help you reposition them.
The way the phone restarts in safe mode varies by device. For information on how to do this, visit the manufacturer's support site.
Step 2: Check if the problem is solved Use the phone normally and see if the problem is solved. In that case, it may be caused by an app. Go to step 3 listed below. If the problem does not go away, it means that it is not an app that causes it.
See the list of other troubleshooting See the list of other troubleshooting solutions.
Step 3: Exit Safe Mode To exit safe mode, you can generally restart the phone in the normal way. How you disable or exit safe mode varies by phone. For information on how to restart your phone in safe mode, visit the manufacturer's support site.
Tip: After exiting Safe Mode, you can put back all the widgets that were removed from the Home Screen. Learn about adding widgets.
Step 4: Verify the apps
1.- Remove the apps you recently downloaded one at a time.
2.- After removing each one, restart the phone in the usual way. Check if that way the problem is solved.
3.- After removing the application that caused the problem, you can reinstall the apps you removed.
NOTE.- To identify the apps that are causing problems, create a list of the ones that you forced to stop.
Other methods factory setting?
Make backup copies because the system will begin to delete all unnecessary files and restart the device once the operation is finished. You need to charge the device up to 100% in advance, because if it is discharged during the removal process, unpleasant difficulties will arise, which you can hardly solve on your own.
With the phone hardware buttons
You can also reset all settings using the smartphone itself, that is, using its hardware buttons. To restart the smartphone, you need to turn it off completely, and then simultaneously press several buttons: "Power" and two volume buttons ("see previous information"). The phone will start to reboot and reboot.
Some developers place a special button to update the system. It is very small and is usually located in the hole next to the power button. To start the operation, hold it with a needle or pencil.
Using recovery keys
This method is suitable for devices that freeze at the startup stage and do not respond to touch on the screen. It is also relevant for users who have forgotten their login passwords.
To reset, press a specific key combination, go to recovery mode (factory software), and start system recovery from there.
If the device does not respond when touching the screen, select menu items using the volume keys and the Power or Home key. (see previous information according to model)
Using a computer
If you cannot reset the settings with traditional methods, you can try to do it through a computer, after downloading the Android system development kit program from the developer website.
After downloading the file, you must:
A.- On the device, enable the USB debugging mode: "Settings" - "For developers" - "USB settings" or "Settings" - "General" - "About phone" - "General" - "Information programs ".
B.- Check the boxes for tools and USB drivers.
C.- Install the drivers for the device on a PC and connect it through the USB port.
D.- Open a command line and write in it "C: \ Users \ Username \ AppData \ Local \ Android \ Android-SDK \ platform tools
E.- Enter the ADB reboot in recovery.
D.- Wait for the system to restart.
Reset with service code
There is another quick and easy way to initiate a system reboot: using a special service code.
1.- Open the telephone keypad (in the calls section) or "Emergency call".
2.- Enter the reset code: * 2767 * 3855 # or * # * # 7780 # * # * or * # * # 7378423 # * # *.
3.- After entering the code without asking for confirmation, the device will begin the factory reset.
