How easy would it be for someone to assume your identity if they had control of your smartphone? Depending on how elaborate your internal defenses are, they would be able to text people as you, post to your Facebook account, maybe even access your bank accounts or make purchases in your name.

Technology has made these strange little devices a part of our identity. The idea that smartphones have become an extension of the self is not a new one. Just as you disclose parts of yourself to some people yet hide them from others, the desire to tuck away files, photos, or applications on your smartphone is a popular one.

Maybe you’ve got some pictures that you’d really prefer your mother not stumble across if she needs to borrow your phone. Maybe you have some private documents that contain sensitive personal information. Maybe you have apps that aren’t quite ‘child friendly’ enough for you to feel safe handing over your phone to your nephew so he can play Angry Birds.

Whatever the reason, there are plenty of options when it comes to hiding content on your phone. We’re going to look at a few of them here and discuss the benefits and risks of each.

How to Hide Files

Most Android devices don’t actually have a stock ability to hide stuff, so no matter what you’re looking to do, you’re probably going to have to resort to third-party apps. Let’s start with the basics and learn to hide some files in general.

A solid app for this task is File Hide Expert. It’s a free app, and it lets you hide and unhide any file on your phone with ease. To get this up and running, first download the app from the Google Play Store. When you open the app, you’ll receive a message indicating that the hidden file list is empty. Tap the folder icon in the top-right of the screen to begin hiding files.


The app works like a basic file management app. As long as you know where the file is located, you can hide it regardless of type. Check off any files you want to hide, and then head back to your main screen.


From here, hitting “Hide All” will spirit away all of your files, making them inaccessible to snooping phone borrowers. They’ll no longer appear in other file managers or galleries. To bring them back, simply open File Hide Expert again and tap “Restore All.”


Of course, this hardly keeps your content safe. After all, anyone can just open up File Hide Expert and see all the files you don’t want them to see in one easy-to-access list. A smart idea will be to use File Hide Expert’s password capabilities.


Tap the Menu button and then Settings. The very first option will be to enable a password. Check that box, and you’ll be prompted to enter a password to use. Be careful not to forget this, because you’ll need to use it every time you boot up File Hide Expert. You don’t want to get into a situation where you can’t restore the files you’ve hidden!

How to Hide Photos

Now, although File Hide Expert technically works for any kind of file you can imagine, it’s not really the most efficient way to hide photos. If you’re the kind of person who like snapping the occasional risque pic every now and then, you might have a better experience with KeepSafe.

KeepSafe basically creates a digital vault on your phone where you can toss anything that you don’t want showing up anywhere else. You have to create a PIN to use every time you want to access your app, and it keeps all of your sensitive files in one location. There is also an option to back your private files up on the cloud, if you feel comfortable doing so. That way you can recover your lost pics if your phone gets lost or broken.

KeepSafe is rapidly becoming one of the most widely used privacy apps, and the current version is free to use with premium features available for unlocking at $4.99 a month. The cloud backup service is free, but the premium version gives you additional features like snazzy PIN theme, a fake PIN that lets users think they’ve gained access to your hidden files if they use it, and a “secret door” that disguises KeepSafe as a utility app unless you long-press on the icon. Premium members also get a “Break-in Alert” system that logs failed access attempts so that you can see if someone else has been trying to get at your private files. In addition to hiding pictures, KeepSafe can also be used as a repository for sensitive data such as passwords and ID cards.


Setting it up is a breeze. Simply download the app from the Google Play Store and the setup guide will walk you through setting up a PIN.


That accomplished, you can add any photos to KeepSafe by opening a folder and tapping the ‘add picture’ icon at the bottom right. Use the browser to select the photos you want to hide. 


Alternatively, you can add files to the vault by accessing your phone’s normal gallery, tapping the “Share” button on the desired picture, and selecting KeepSafe from the list of options. This will move the photo to your private collection and remove it from the gallery. Easy peasy.  

How to Hide Apps

Ever get tired of seeing that damn NFL Mobile app that came with your phone and which you can’t uninstall without rooting? Is your app drawer getting crammed with apps that you rarely use, making it a headache to get to the ones you want? Hiding apps is a good way to clean up your app tray and keep guest users from stumbling across any apps you’d rather keep your own business.

Some stock launchers offer this functionality right out of the box. Most Samsung users, for instance, have the ability to hide apps without leaning on third party apps. If your launcher doesn’t support app hiding, give Nova Launcher a spin. It’s an excellent launcher all around, and it gives you the ability to hide apps with a simple and intuitive option.

Install Nova Launcher and open the app drawer. Navigate to Nova Settings > App & widget drawers > Hide Apps. Select the apps you want to hide, and they won’t show up on your app tray anymore.


To reveal an app again, simply return to the same menu and uncheck the desired app.

A Stock Fix

There’s a crazy easy way to hide whole folders without using third party apps. This simple fix will prevent photos from showing up in galleries, audio files from showing up in players, and documents from showing up in editing apps. However, the files aren’t particularly hidden, because all you’re doing is renaming the folder in such a way that Android ignores it.

Using any Android file manager, simply add a “.” to the front of the folder’s name. If you want to get super sneaky, try renaming the folder something boring like “.simdata” or “.systeminfo” or whatever.


Remember that these apps were created to keep files out of the hands of casual guest users. If someone with the right knowhow is really serious about getting at your private data, they’re going to be able to circumvent the methods these apps use to keep your files and pictures out of sight. The best security is to make sure that such people don’t get ahold of your device, and to make sure you’re using a secure lock screen. Consider hiding very sensitive content on a non-mobile device.

These are our suggestions for hiding files, photos, and apps. Do you have privacy methods that you prefer over these? If so, let us know which ones and why in the comments!

    To hi dean entire folder without renaming it, go into the folder (via a file Explorer app) then create a new file and name it “.nomedia”. It will hide the folder and the contents however, it can still be seen in the Explorer app.

      Hi I just renamed one of my folders adding a period (ie from aaaa to .aaaa). now i cant see or find the folder in list of folders. can u pl help? I want to rename it back without the period !!

      • kimi

        i use one plus 3

        • My Galaxy Prime

          Which file system app are you using? I can help you find the folder

  • urbanpitch

    I know this is going to sound insane and cumbersome, but I put my files, folders and photos into a zip folder and extract and compress then when I need to see them or add more. Password protecting them is pretty easy too. It doesn’t work for apps but that’s just one thing i guess.

  • abdel

    Samsung private mode :)
    Unlock with fingerprint

    • Lindle

      Extremely expensive since you have to buy Samsung.

      • Maximillian

        My issue with that is the fact that my s6 active doesn’t have a fingerprint scanner to be waterproof.

    • BondSan

      One of the great and well thought out features of TouchWiz. A lot of the TW features are lame and useless but it has an equal amount of fantastic ones, and private mode is one of them. I’d rather not have an app made by Ben Schmo in Hoboken as a bucket for all my sensitive pics and data. Who the hell knows what the app does. Samsung is a much more public company and either would not be up to no good OR, if they are, then they are not going to be interested in some shots of my gf… Ben Schmo on the other hand would. Vanilla android is great, but you have to go and hunt for all these types of somewhat necessary apps all of which come from unknown developers and have ads or poor implementation.

    Audio manager is the best to hide apps. For some reason it no longer launch the app without unhiding the app first. Before i was able to launch hidden app from audio manager and as i press the home button it automatically exits the app the hide it too. Life saver when someone bumps in and you have to exit the app and hide it automatically.
    For other files i have a separate folder by filename “.private”. And use es file explorer to view them.

  • If you want to hide media files you can just copy a .nomedia file in the folder that contains whatever photos you want to hide. That way they won’t show at least in the bundled media apps, like Gallery.

  • Niyazi Karakus

    What about just create a “Guest user” profile! It is best solution without third-party apps!

  • KRB

    I use QuickPic from the Android Play Store. It’s a gallery app that has a Hide feature for photos and videos. You simply activate the feature by drawing a PIN pattern, then designate which photos, photo albums, videos or video albums you’d like to hide. When you want to see your “photos” or “videos” you simply select Unhide and connect the dots that you set up as your PIN. It works just like those whom use the dots as their PIN to unlock their phone, so there’s infinite combinations… To further hiding my pics I use ES File Manager which not only has a PIN feature itself but also you can hide folders and files…

    But I’ll have to try these others out as they sound really interesting…

  • Aneesh Bansal

    Well i want an app or procedure to hide or protect video & picture files, they should run as normal in mobile, anyone can see and watch them but cannot able to delete it…. please help me out…. do mail me at

  • Απόστολος Στάβλος

    Well, every time i come across such apps or tools there is always some kind of reasonable mistake with it.
    I mean, people would like to hide things mainly for two reasons: Either for the case their phone ends up in stranger’s hands or to keep some kind of secret from their boyfriend/girlfriend etc. If you use an app to hide another up or to password-protect it, there is still an app-hiding app in your phone, the other person is not stupid they can always assume you’re hiding something since they see that app or because a pass is required to open something.
    A good app of this kind would be something that hides/shows something else (an app, a chat, a photo, whatever) without making it obvious that something is hidden. I could thing of certain ways to do that (maybe by dialing a certain number) but the thing is, nobody has done it yet.

      It’s about privacy since it’s not your phone. from the start. Everyone have secrets and everyone knows that so hiding sometimes doesnt mean you have secrets, it’s about privacy. I think it’s simple enough to say “What? It’s my phone. Who gave you the permission to touch it?” like this. I just dont like it when people get their hands on my phone. It’s personal stuff!!!

      And also if you lost your phone these apps can be a life savior for you in some situations.

  • Devendra Bhat
