How to delete data from an Android phone before sale (guide)

Sprzedaż smartfona to w obecnych czasach poważna decyzja. Gromadzimy na nim wiele ważnych danych, które składają się na naszą e-tożsamość.

How to delete data from an android phone

Google has been taking care of the security of user files a bit more comprehensively for some time.In a nutshell, if your device works on Android 5.0 and a newer, the best option is to use encryption that is included in our smartphone.Few people know that the device has such a function, so it is worth making sure that the encryption mode is active in our phone.

Remember, later recovering your data from one phone to another is even very simple, but you have to remember a few small details.If you do not follow them, a simple walk through the forest can change into a dramatic struggle to recover key data, including contacts.

Remember that:

How to transfer data from one smartphone to another #pdp #3

If you do not know where to look for information about encryption, the search engine in the device settings comes to the rescue.Usually, if you enter a phrase such as "cipher" or "encryption", then the device will immediately tell you the search result in which you need to tap.Things are slightly different in new smartphones from Samsung.Here we have to find the "Safe start" tab.The tool will force the pattern to provide, without which all data will be encrypted and the user will not access them.

We reach two scenarios here.The first assumes that you had encryption on your devices.In such a situation, you can assume that your data is secure and after restoring the factory settings, the bystanders will not be able to access them.Of course, there are some deviations from this rule, but we are not talking about software straight from movies about Agent 007.

In this situation, you only need to secure your contacts and data, for example in the cloud or transferring them "on the cable" to your computer, and then you have to enter the settings and restore factory settings.Remember to transport data from the microSD card and remove it from the device before selling out.My experience shows that many people still forget about this step.The smartphone will ask you to provide a pattern or safety code you have chosen before and after a while you will be able to erase your data from the device.

The whole procedure may take a few to several minutes, depending on which smartphone you have.After this procedure, you will be greeted by an Android installer.As many different phones pass through my hands, I always recommend passing this quick configuration without logging in to my account and without connecting to the WiFi network.Just configure a clean system without securing the device with any pattern or through a fingerprint scanner.Their slightly more zealous can connect the device to the computer and try to force the recovery of files by public (and often free) software.If you have done all the steps well, the tool should not be able to recover any of your data, including photos.

Skeptical variant

Let's assume that it turned out that your phone has no data encryption mode enabled.What can you do in such a situation?First of all, make sure that the smartphone is charged;) The easiest way out of the situation is to make a backup for such data as contacts, applications or text messages and downloading a secured data packet using the tools provided by the software manufacturer provided.I went through this procedure on a smartphone from Samsung, earlier also on products with the Huawei logo and I can assure you that these solutions are well optimized and simply work.

After performing this activity, you enter the security settings and activate the encryption function.The procedure may take a while, therefore - apart from the charged battery - you will need something to eat and drink.The choice depends only on you;) If there is a lot of data on the smartphone, and it is not a device of the highest flights, then all the fun can take up to an hour.At this time, you will not be able to make phone calls.You will simply be cut off from the device.

After completing the encryption procedure, the device will start.You will have to provide a previously set pattern to unlock it.If everything went according to plan, you will see all your data unchanged.Now all you have to do is restore the phone to the factory settings, previously making sure that a copy of the data is safe in the cloud or on another medium, such as your computer's hard disk.

Moving data from games

Finally, it is worth devoting a few sentences to the safe transfer of our games from games.Not all titles integrate with Google Play Games, so it's worth having a plan in the ambulance.It is worth bending over the Helium application.You will need a version for Android and Windows.Importantly, the tool does not require root, so it can be used by even a layman who expects only to work from a smartphone that he works and allows you to play games and take pictures.

Remember to remove the microSD card before cleaning your old smartphone;)

After installing the application.The next step is to choose a medium where files are to be found, and then we just have to wait a little.If you download Helium to Android, it will be necessary to be a microSD card, at least in the free version of the application.Pro (paid) version enables data export to such services as Dropbox or OneDrive.

I restored the factory settings on the smartphone after almost two years.Was it worth it?

When the program finishes its work, the next step is to install Helium on a new smartphone and restore copies from the indicated medium.If you decide to send data "by cable", using the Windows version, your progress in games will be saved on the computer's hard disk.Later, you only need to install the customer's application on the new phone, select "Restore" and wait a while.

The software is not perfect, but it seems to me that this is one of the best options you can choose.Helium has been downloaded from the Play store more than a million times, collecting an average rating of 4.1.

And what are your experiences with cleaning Android devices and restoration of backups?Maybe you will recommend readers some of your proven patents?Let me know in the comments.
