Diskdigger is a useful tool for Andriod users

We check if the smartphone is pale.

The first thing that the officers do during the arrest is "squeeze" the means of communication. Firstly, to prevent situations when one member of an organized group warns others about his detention, and secondly, to prevent the destruction of such evidence as SMS calls, and most importantly - photos and videos. The provider has the call and SMS logs, but the photos are stored locally on the device.

Since Android is a "close relative" of Linux - file systems work the same there, including in terms of deleting data - after deleting a file, it is not actually deleted, the system only marks the area on which it is written "open for overwriting ", and for now this area will not be overwritten the file will be available for recovery.

Everything would be fine, but the fact is that recently the size of information carriers has grown very much. The capacity of hard drives is already measured in hundreds of gigabytes or even terabytes, and the capacity of memory chips in mobile devices is measured in gigabytes or even tens of gigabytes. At the same time, the size of the files themselves increased slightly, as a result - a huge amount of unallocated space on the media. The system, first of all, will write new files to free areas - and only when they run out will it start overwriting areas with "deleted" data.

You can check what the expertise can get from a mobile device using the DiskDigger application (https://www.diskdigger.org ), which is also available on GooglePM.

There are two types of audit available in the application - "simple" and "root". Ruth pulls out more, checked many times. But a simple one can also do something.

How to be?

1. We encrypt the smartphone, if it is not already encrypted.

2. Remember that the "cart", even with disabled multimedia autoloading, still automatically downloads and stores all avatars.

3. We take "empty" space on the device with 2-4 large files (I store Linux distributions - weighing 1-2 GB each) so that the remaining space is often overwritten.

4. Regularly go to the settings - apps menu - select the application that you use as a gallery, as well as a file manager (they produce "previews" for jeepgs) and click first clear cache, then clear data.

We regularly check with a digger. If it does not help, we do a hard reset and re-encrypt the date section. Can be a couple of three times to be sure.
