To hide or privately make files such as videos, documents, and images on Android, you don’t need to download and install third-party apps. Here are the easiest ways to protect your most valuable information.
If you need to hide or block access to private and confidential images, and you have an Android phone, you have numerous tools at your disposal to achieve this. without the need to install third-party applications.
For several years now, this operating system has greatly improved the entire privacy-related section, with several features that allow you to block unauthorized access to a user’s most important files.
Although a password—pattern, PIN, or alphanumeric lock—is usually more than enough for no one to try to access your phone, in some cases you may need additional protection to specifically block what you don’t want anyone to see.
Maintaining this kind of stricter privacy is often almost mandatory if you share your phone with another family member, often leave it with your child to spend some time with, or simply handle important files.
These are all the ways you can turn your Android phone into a totally secure and private safe without having to download third-party apps.
Create a privacy password
The fundamental step in hiding or locking your most important files, whether they are images, videos, or documents, is to set up a privacy password.
This is mandatory if you are going to configure stricter privacy, and it can be an unlock pattern or a numeric or alphanumeric PIN, and it is always best to be different from the screen lock for greater security.
Its creation is really simple. To create it, you have to select the settings of your mobile and choose the privacy and security tab. Within this menu, you will find something similar to a More Security and Privacy option, where the Privacy Password is located.
Create the one you consider best, but remember that you will have to keep it well in memory; if you lose it, you could face additional problems, not being able to access your hidden applications or files.
In any case, with the functionalities that we explain below, it will always ask you to configure this password beforehand, so you could skip this first step and directly configure the following.

How to Hide Private Photos Android Without Installing Anything
The first method I’m going to talk about to hide your images is to use the Google Photos application—pre-installed on Android devices—or the Photos or Gallery application that arrives with your manufacturer.
This setting is the best one you can use if you don’t want to hide an image or video in question but directly block the entire application. To do this, visit the same Privacy & Security menu in your Settings.
Although it may be called differently, find the App Lock tab, turn on that feature, and choose the service you want to hide. In this specific case, it would be all the apps to manage photos and videos.
If your manufacturer has an app in question to review these types of files, block this one as well. Each time you want to sign in, it will ask you for the privacy password you have created.
Another way to block this type of content, and one that works in a very similar way, is the Hide apps option, available from the same menu. This manages to hide the app on the home screen, the notification panel, or recent tasks.
To be able to unlock hidden applications, you will have to dial the code in question from the keyboard of the phone application, always between pads.
Finally, if you want to create a kind of safe—a name used by some manufacturers for Private Space on Android—you will have to choose this option in the same privacy and security menu.
Like the previous ones, it allows the apps or folders you select to be inaccessible if you don’t have the privacy password.
