1. Device Encryption
Encryption is a way of encoding user-selected information to another standard, usually a password. Therefore, if this information is accessed by unauthorized persons, it will have no meaning: only with the encryption password can you make the information readable again.
That is, after encryption, only through password confirmation can the data be accessed. The encoding process is complex and irreversible, so we recommend that you follow all the information given in the article below to set up the feature on your Android.
2. Automatic backup of images and files
Many users choose to use microSD cards, which keep images safe in case of operating system problems. However, some devices do not have a card slot available, and the best method for these users is to back up via cloud storage services.
Google Photos is the best option for keeping your images and videos safe. The Google service offers some options for automatic backup and sync on your first install. If you did not set up when you first installed the app, you can use the Google Photos settings and enable the "back up and sync"
Images can be accessed from any device at photos.google. All information on how Google Photos works can be found through the article below:
Now, if your concern is with documents, such as PDF and Office files, Google Drive may be the best option to keep them safe. The service stores and makes files available for offline viewing from any device. In addition to Google services, alternatives such as Box, Dropbox and OneDrive offer solutions for automatic file backups in general.
3. Use 2-Step Authentication
Two-factor authentication, also known as two-step verification, thus adding a second protection to applications and services. Many of these already have this option, such as Facebook, Twitter, LinkedIn, and WhatsApp. In these apps, look for the "security" session and set up two-step authentication. The Google Account also offers this option by linking the second password to a phone number, just like PayPal.
4. Backup Contacts, Emails, and Applications
Android offers a backup option that keeps contact, email, and application information saved on Google's servers. Information stored through Android can be exported to other devices. For that, go to the option "Backup and Restore"through the" menuSystem Settings"
Select "Google account"and enable synchronization of your information by checking the options you want to save.
This option is especially useful in cases of theft, where the user needs to retrieve their information from a new device. Remember that contacts stored on the operator card must be exported to the internal memory of the device.
To do this, follow the path: Schedule (people or contacts on some devices) > Settings (three points in the upper right or lower left) > Manage Contacts> Import / Export and select "export to internal storage"Select the desired contacts and wait for the process to finish.
5. Lock screen and apps
Android has several options for screen locking, such as alphanumeric passwords, PIN, or sequential dot design. To keep your Android protected it is recommended to use any of the options available on the system for screen lock. This will prevent easy access to personal information stored on the device.
To enable screen lock v at System Settings> Screen Lock> Select Screen Lock. Select the desired pattern and proceed with the necessary steps for configuration.
There are other options that increase device security and can be downloaded through the Play Store. AppLock adds a user-configured password pattern for various applications installed on the device. You can set a password to open Gmail, WhatsApp, Facebook, and even the Play Store.
During the first installation I need to provide an email for password recovery in case of forgetfulness. You can download the application via the button below the following image.
6. Hide photo albums on Android
If you want to keep your privacy, there are a lot of options on Android. One of the most used is the ability to hide folders. So for those who don't want someone opening the image gallery, how about hiding the photo album? The good thing is that the process can also be easily reversed. All without root access!
If you don't want to download third party applications as shown above, and password protect your photos, just use a file called ".nomedia". This type of file in a folder is a system indicator to ignore the contents of that folder. Therefore, if you insert this bookmark into a photo folder, the contents of that folder will no longer be shown in your gallery.
ES File Explorer
To make the process easier, download a file management application such as ES File Explorer. Then search for the folders you want to hide. Photos are usually in the "DCIM" or "/ sdcard" folder. You can also hide photos from specific apps, such as WhatsApp folders, for example.
Once you have found the folder, simply click the "+ (New)" sign in the bottom left corner of the screen and select File. When the window to name it appears, type ".name" and save (do not forget the point at the beginning). That way, the next time you go to the gallery, the contents of that folder will no longer appear.
If you want hidden folders to reappear, enter your file manager settings (no ES Explorer just click on the blue globe in the upper left corner) and enable the show hidden files function (called "Show hidden files"). If they don't appear immediately, clear your gallery app or media server cache.
7. Hide your passwords
On Android, you can hide passwords, from the lock screen to application-specific passwords like apps like Facebook and Twitter. To do so, access Settings> Security> Security Screen> uncheck the "Make default visible" option.
Then go to the "Passwords" option on this same screen, and uncheck the "Make passwords visible" option. Now, every time you enter a password, by gesture or numeral, you won't risk seeing and identifying your password.
8. Check and adjust application permissions
If your smartphone already runs on Android Marshmallow, you'll probably keep an eye on the permissions of each app easier. However, even in previous versions of the system you can know what permissions each app on your phone needs to work.
So pay attention to the description of the apps you download from the Play Store, as you will find what kind of access the app needs on your smartphone. Still, when installing an app you can also see this type of information.
In Marshmallow or Nougat, after you enable a specific permission, such as device camera access, the app will stop requiring such permission again. But be careful, as some permissions are important for the service in question to offer its resources.
9. Device protection and tracking
Google offers a device locking and tracking system that can be used if your device is lost or stolen. Android Device Manager allows you to remotely lock and erase a device through the google/android/devicemanager page. You can also download the official app that has the same features and purpose:
Find my device
To do this, the lost device must be connected to the internet, and preferably with location services enabled (GPS).
10. Secure SMS Messages
If you still use SMS, or then value the security of your messages, even in groups, you can choose to use applications that offer protection beyond conventional encryption. These apps, such as Signal Private (below), work anonymously, examining the security conditions of the server that will send or receive the message, as well as the identity of the sending contact. One more layer of security.
