How to delete data on your phone. How to completely clean an Android device? Step-by-step instruction

A paradox is often discovered in Android phones Samsung Galaxy, Duos, Lenovo, LG, Nokia Lumia, Asus and others.

Some owners cannot recover deleted photos, while others cannot delete deleted photos - an interesting situation.

Everyone wants to completely and permanently delete photos and all personal data, for example, before selling an Android smartphone.

The trick is that even if you do a hard reset of the phone, it will not be enough, since all files can be recovered. How to get rid of them forever without the possibility of recovery?

By the way, there was a way to delete photos (and not only pictures) faster and more efficiently -

Why are deleted photos recovered on Android?

There are several reasons why deleted photos are restored on an Android phone, and not everyone knows that deleting from the gallery, and even restoring the phone to factory settings, does not actually permanently delete your data.

You can very easily recover all files deleted in this way using a file recovery program.

Moreover, Android has synchronization, for example, in the Google Photos application, where everything can be restored automatically.

The same applies to the onedrive cloud, backup auto, hangouts, picasa, hotmail or autobackup, but you can still permanently delete them.

The standard way to delete photos from an Android phone

Wherever your photos are, on the memory card, in the internal memory, they are displayed in the gallery.

You can remove photos from the gallery using Android tools. To do this, open the gallery and click on the option at the top right.

Then click on the “Edit” option.

Now, as soon as you check the boxes next to the files you want to delete, the “Delete” option will immediately become active.

Click on it. A confirmation request will appear - confirm everything.

How to completely permanently delete deleted photos from an Android phone without the possibility of recovery Android

Permanently deleting files is not the best option, you are better off using special applications that do a special process of overwriting the free space and thus, recovery will be prevented completely and forever, with the exception of synchronization.

In order to completely delete a photo, you must perform a standard deletion or restore your smartphone to factory default. This is always a good basis for deleting all personal data.

Then you can use the “iShreddera 5 Standard” app, otherwise your data can be easily recovered.

In fact, deleted photos are not deleted, but only information about them is erased, and they themselves are still in the internal memory and on the card.

IShreddera does not delete current data, but overwrites memory using special algorithms that will prevent the subsequent recovery of private information.

Using IShreddera is very easy. Just launch the application and click on the "Next" button. Then select the section and which algorithm to use.

The more repetitions, the higher the efficiency, but the longer it takes to rewrite. All available algorithms are popular and are used by government organizations and the military to get rid of data. Ideally, you should select 3x repeat and start re-recording.

There is another program called Secure Wipe that also performs similar operations on your phone.

This allows you to overwrite the free space on the memory card and internal memory of the smartphone. If you want to use emergency photo deletion, you can use both applications.

Attention! The process carried out by iShreddera and Secure Wipe can take several hours depending on how much memory you have on your phone. Therefore, it is recommended to connect it to charger for this time.

How to delete photos from Picasa gallery on Android

An Android phone can synchronize your photos with a gallery through Picas or Google Photos. These albums can be deleted, but next time they are synchronized they will be added again.

Luckily, there is a way to completely remove Picasa or Google Photos albums from your smartphone. This requires minor changes to the synchronization settings.

To do this, go to the settings of your smartphone or tablet and select Accounts -> Google.

Select a Gmail address. If your phone has more than one Gmail account, you'll need to repeat this process for each email.

After selecting your email, you will see your account sync options. Uncheck the option to sync Picasa albums.

Go back to Settings and select Settings > Applications > Gallery or Pictures. Click delete data. This process may take some time.

After deleting photos, they can literally appear again in an hour as if nothing had happened.

This happens through synchronization with Google services or through the cloud, for example, in Microsoft phones.

To check this, simply turn off the Internet. If your data stops appearing on its own, then it’s definitely a matter of synchronization with cloud storage.

If the problem occurs on the memory card, then simply try replacing it or formatting it on your computer.

That's all. In the near future I will write how to delete a photo from a Facebook contact, in Contact, via a computer, from Instagram, on Mamba, from Viber, from WhatsApp, from ICloud, from Badu, from Avito Photo, all, in Ask, from WhatsApp, duplicates and all straightaway. Good luck.
