Many times it takes recover a file that has been deleted of an Android terminal, but there are times when the opposite is sought: that what is deleted is sure that it will not be accessed in any way again. Well, this is exactly what is achieved with the application Secure Eraser.
By using this development, what is done is to eliminate any trace that remains in the internal memory of the phone or tablet in which it is used, so it will not be possible to recover in any way that are currently known to do this (such as using the development called Undelete). Therefore, Secure Eraser provides security to the erasure, but this must be taken into account since we are talking about an irrevocable process.
Basically what you do with Secure Eraser is write new data -one or several times, as necessary- in the free space that you have on the Android device, which permanently eliminates the information that is in each of the cells of the internal storage memory. In this way, it is not possible to recover the information since it has been permanently deleted from the device in question.
Use Secure Eraser
The use of this development is not complex at all. But we remember that carrying out the indicated process eliminates the option of being able to recover the data (something that more than one user has subsequently needed, so you have to be very sure of what you are doing). By the way, Secure Eraser offers the option of working both with the internal memory as with external using a drop-down menu at the top.
Once you have chosen this and selected the method to use, the ideal is to leave the one called Random (its effectiveness is very high), you just have to press the button called Start -Secure Eraser is not translated, but it is hardly dependent on the language- and wait for the process to finish. That is how simple everything is.
The download of Secure Eraser is done in the Play Store using the image that we leave below and you do not have to pay anything for it. The minimum requirements are also very low: Android 2.3 or higher and 2 MB of free space. The fact is that this development is a good tool for when a mobile terminal is sold or given away (and, in this way, make sure that there is nothing left inside).
