"Not that this is a guarantee that your information will be 100% safe, but the risks are lower," he says.
2. Remove the memory card
If the device count on a removable memory card, make sure that all personal information - such as contacts and pictures - are saved it and pull it out to bring the device to repair.
3. physical backup
For smartphones that do not have the removable memory card - such as the iPhone and the new Galaxys - the safest scenario, according to Fabio Assolini, Senior Analyst Security Kaspersky Lab Brazil, is doing physical backup smartphone. "Connect the device to your computer and perform a full backup of all files, applications and settings," he suggests.
4. Refer to the backup in the cloud
For those who do not have a computer, the option is to do a backup in the cloud. "The security of this storage depends on how it's done," said Assolini. To be safe, he said, is necessary to resort to a good password, as well as two-factor authentication. "This method requires, in addition to the password, a code sent to the mobile phone at the time of login"

With the files and the saved settings, you must make the so-called "hard reset", which in addition to erase all the data, restore your device to factory defaults. The process is fairly simple on any operating system.

6. Encrypt the phone
The use of encryption, such as points Filev, is also effective resource for guaranteed privacy of the files on the smartphone. According to him, there are some free software on the market that offer the folder protection and / or specific files. "In general, they are simple to install. The big problem is that end up leaving the slower devices, and consume a little more battery."
7. Avoid obvious passwords
Beware passwords! After all, there is no point using cloud services or protection programs if the chosen password is fragile. Assolini suggests that the access codes are not sequential or repeated numbers, family names or dates of birth. "The ideal is to create a unique password and with at least six figures." You should also switch uppercase and lowercase letters, and use special characters ($, @,!, #, Etc.).
8. Delete the files
If the option is off intimate photos or any classified document, the important thing is to resort to destroying files, as pointed out by Bruna. "Even when deleted, the files can remain on the hard disk and, in some cases, can be easily recovered by file recovery programs," says the researcher, who says there programs - including free - to eliminate the traces of the files. One of the suggestions, she said, is CCleaner, available for Android (click and check).
