How to reset a Samsung tablet to factory settings

The need to restore Samsung phones or tablets to factory settings arises when problems with the Android operating system occur. The cause of the problem may be software installed from unknown sources, a large number of games on the internal and external memory card, or incorrect user actions. After this, the mobile device begins to work unstably or stops turning on altogether. And a system reset, system or hardware, is the best option to restore functionality.

Resetting data via menu

The most effective way to restore the tablet to its normal Samsung state is to reset or so-called rollback to factory settings. To use this option, repeat the following:

1. Open the system menu and select the “Settings” section;
2. Go to the factory reset item (usually located in the “Backup” or “About the system” section, depending on the version of the operating system);

3. Select full data reset.

A message will appear on the smartphone screen indicating that all data must be deleted and recommendations for saving a backup copy on the device or cloud storage. Confirm your action by pressing the “Ok” button - the rollback process will start.

How to set a password for an application in Samsung

This method is great not only for tablets, but also for smartphones running the Android operating system.

What is a factory reset and when should you use it?

Resetting the settings or hard reset of any mobile gadget on Android (not only Samsung Galaxy) is clearing its permanent memory of all applications, settings and files, except for those installed by the manufacturer.

The reset function is for:

• Restoring the device’s functionality in the event of software problems and malware infection, when the failure cannot be resolved by more gentle methods.
• Preparing a gadget for sale or transfer to another user.
• Optimizations after firmware update.

After a hard reset, no user data remains on the smartphone, except for those stored on the removable memory card and SIM (contacts). However, in some cases, changes made by the user are still saved. Namely:

• If the device had root rights before the rollback. Pre-installed applications deleted with superuser rights are not restored after a reset.
• When FRP (Factory Reset Protection) is activated - enhanced protection of the owner’s data in case of loss or theft of the phone.

A device with FRP enabled, even after a hard reset, will request the user account password, without which access to the system is impossible. Therefore, doing a rollback on such a device in order to delete a forgotten password is completely pointless.

Entering the service code

For tablets with a 3G module, it is possible to reset the system by entering a special combination of numbers and symbols. To do this, you need to open the telephone dialing functionality (green handset icon on the desktop) and enter one of the suggested codes:

*2767*3855# – universal code that works on most devices;

*#*#7780#*#* or *#*#7378423#*#* – specific combinations used if the previous code did not work. After the number combination you need to press the call key. This will start the reset procedure.

Samsung Service Center

Unfortunately, it is not always possible to resolve the issue on your own. All the methods described above only work if the device continues to function, albeit with malfunctions. If the device no longer turns on, or the actions you perform do not give the desired result, we recommend contacting a service center. It is especially recommended to use this option if the device is still under warranty. Experts can not only fix the problem, but also give recommendations on how to avoid a recurrence of such a situation in the future.

Contacting service

System and hardware methods for resetting Samsung mobile devices are only suitable for situations where they continue to work. Sometimes, using the Recovery menu, it is possible to start and restore to the factory state the system of a tablet or smartphone that for some reason has stopped turning on. But, if none of the methods helped, and the device not only freezes, but also stops responding to user actions, you cannot do without contacting a service center. Sometimes settings are restored even under warranty.

Samsung C3300, then try to follow a few rules: Be patient. Find an hour of time so that no one and nothing distracts you. Calm down, collect yourself, concentrate.

• What to do if you forgot your Samsung Pay password?

Remove the SIM card and memory card from the phone. Turn on your phone. Hold the side lock button to release the lock. Go to dialing mode. Take a close look at the dialing keypad. Remember, memorize the placement of the buttons that need to be dialed. Don't forget about the buttons and #. I recommend starting with the code 27672878#. Practice typing a composition. It is not good to distract the operator of a critical call service by practicing how to quickly and accurately dial the required combination. Read the entire procedure in advance. Now, when you dial the combination quickly and accurately, you understand the procedure, of course, move on to dialing the critical call number 112. Dial 112. The phone will ask the question “Critical call?” Click "Sell". The screen will be locked, and a corresponding message will appear: “Press the HOLD button to unlock” with the usual image of a lock. However, the cinematic lock mainly does not unlock the screen. You must press and hold the side unlock button. Maybe after unlocking the screen will lock again. Unlock the screen again. Do not pay attention to the fact that for you it says what else it is called, the operator does not say it, otherwise the answering machine says. To make a keyboard appear for typing a song on the unlocked screen, press the “Dial” button (the leftmost button of the three “Dial” “Sound” “Contacts”). Relax and evenly type the memorized combination without confusing or even skipping special characters. 27672878# The next reason is that the four digits will not appear on the display. Only dashes. This is fine. It will look like 2767 If everything was done correctly, then the corresponding message in British “E2P Custom reset” will appear in the cinema. DO NOT PRESS ANYTHING! Wait while the phone performs the necessary actions. The operator will swear, you can say “Sorry, we dialed by accident,” he will hang up, alas, this is no longer so important for the phone.

How to disable the screen lock in the standard Android interface?

In general, on most Android models, the lock is disabled as follows:

1. Go to the device settings menu and select the “Security” section, which is located in the “Personal Data” block;

1. Now you need to visit the “Screen lock” section, note that if the password unlock function is enabled on your smartphone, you will need to enter the existing password, because Without this procedure you will not be able to go further;

1. A list of available locks will open, where you can change or select a new type of lock; we need the “No” option;

In general, the locking process for all models is approximately similar, therefore, using these two methods, you will be able to disable the lock and gain access to the device many times faster.

Unlock options

• Your phone may be completely blocked by your operator or only locked for use on its network. You could also accidentally block your mobile phone or SIM card or memory card.
• This determines what actions need to be taken to unlock the device.
• Unlocking also depends on the mobile phone model, for example, for outdated models there are master code calculators; by feeding them the IMEI of the phone, you will receive the required unlock code. So it's all very individual.

A few words about competitors

The reliable Finnish mobile phone Nokia does not need advertising. At the same time, the question of how to remove the lock from a Nokia phone is no less relevant. However, earlier models are practically impossible to “manually deactivate,” and modern smartphones have even more reliable protection than their predecessors. Of course, you won’t be able to unlock the Finn with any service codes. Unless using the same ID account.

Of course, this function is supported only by new cellular communication units; for other representatives of the Nokia line, only firmware and complex software manipulations remain. However, we are still presenting to your attention a method for unlocking some not particularly capricious modifications, representatives of which are relatively outdated samples of serial production.
