Why do you need a data reset?
Resetting device data (settings reset, hard reset, factory reset) is the deletion of all data from a smartphone or tablet: contacts, messages, downloaded applications, photos, music, mail settings, alarm clocks. After the reset, the smartphone or tablet returns to the factory state.
Usually data reset is done in the following cases:
- Before selling or transferring the device to another person;
- If there is a problem on the device that cannot be fixed in other ways;
- After update software devices (firmware).
What to do before data reset
1. Copy important information from the device.
During the reset, the device memory will be cleared and all data will be deleted. If there is any important data, make a copy of it.
2. Remove your Google account from your device.
If this is not done, then when the device is turned on after the reset, the account that was on the device before the reset will be requested. Without entering this account, you will not be able to turn on the device.
The first way to do a data reset is through the menu
The second way to do a data reset is using the buttons
This method is used when the smartphone or tablet does not turn on, or the screen is locked.
If the device does not turn on after the reset, a Google account is required
If the device does not turn on after the reset (freezes)
Contact the Samsung service center, you need to reinstall the firmware by an engineering method.
Resetting user settings to factory settings will result in the loss of all your data that is saved on the device. In some cases, it is necessary to roll back the settings in Android in order for it to work normally again. Fortunately, there is nothing complicated about this.
Manufacturers of almost all Android devices provide a quick factory reset using the special Recovery menu and using the volume and power keys in certain sequences.
However, there are exceptions among them, where, due to the design of the case or the location of the keys, the reset occurs in a completely different scenario. But these smartphones are a very big exception. If you have such a device, then carefully read the documents attached to it and / or contact the support service provided by the manufacturer.
It is advisable to make a backup copy of all the necessary information that is recorded on the smartphone before starting work.
The instruction for conventional devices looks something like this (there may be slight differences depending on the device model):
Method 2: Android Menu
You can use the instructions from this method only if the phone turns on normally and you have full access to it. However, in some phones and versions operating system it is impossible to reset through the standard settings. The instruction looks like this:
As you can see, the instructions that are relevant for most smartphones on the modern market do not differ in any complexity. If you decide to "demolish" the settings of your device to the factory settings, then carefully consider this decision, since deleted data is very difficult to recover.
In devices based on the Android operating system, there is a section with which you can reset the settings (Hard Reset) of a tablet or smartphone, which, by the way, we are talking about. Some users are wondering what happens when this happens.
Resetting to factory settings is necessary for the user if, for example, he wants to get the device in its original form, since when resetting the settings, absolutely all data is deleted, including photos, videos, applications and other files, and the system returns to its original state, including all settings. It is for this reason that it is necessary to make a backup - saving data in case you still have to do a Hard Reset. Phone numbers can be retrieved using Google account if this information is synced with the account.
There are other reasons for resetting the settings. So, the device may start to work slowly, slowdowns, glitches, etc. appear. If this is related to any application, it is advisable to remove it and check the system's performance, but if you do not know what's wrong, you can reset the settings.
So the only disadvantage of resetting the settings is the loss of data, which the system warns about. Some users do not know this, and then wonder where all their photos, music, videos, etc. have gone. Once again, if you need this data, transfer it somewhere else before resetting it, for example, to a computer or to cloud storage. After the reset, you can download them back to your device.
