How to lock apps on Older Android Versions

Smartphones are like toothbrushes: it does not lend itself. Okay, we can lend them but do not dig in too much. If you’re the kind of person who does not like being searched on your smartphone when you lend it, be aware that you can lock apps so no one can access them. We explain how to do it in our tutorial.

Solution 1: with the manufacturer’s safe
Some manufacturers offer this feature by default. This is notably the case of Samsung which, since the late Galaxy Note7 , offers its Secure Folder. This private area allows you to “hide” your photos, videos, files, applications and other data from prying eyes. Note that this secure folder, Secure Folder, is also available on the Play Store if your Samsung device has not already installed it.

Solution 2: from a dedicated application
Unlike other, more closed operating systems, we can not tell you enough that the Android OS has definite advantages in terms of customization and configuration. Available to users through the Google Play Store or other markets / online application platforms, there are many alternatives, but which one to choose? To have tried a number, I made the decision to make a selection that I then sorted by genre and compatibility since everyone does not have the latest version of Android or the last function at the fashion.

Note: All apps on the list are available for free download.

With Android 1.6 or later

If your mobile device was blocked during the Cro-Magnon man’s era, do not give up as there is a solution, compatible for Android 1.6, which blocks access to applications.

Called Super AppLock, this application does not have a sexier design, but it will allow you to block access to all or some desired applications using a password or a diagram. In addition to taking less than a small megabyte in the memory of the device, the application is very easy access to customization with a range of options that could inspire others. In addition to providing a constant lock to the applications you want, Super AppLock will also ask for a password to access its settings, which is complemented by an emergency recovery method by email in case of forgetfulness. Rather useful!

In the manner of some Android features, Super AppLock will also be able to hang depending on certain situations that are: your location (by unlocking automatically if you are at home for example) or at desired times in the day (depending on the hours). In addition, be aware that the interface of the application can be customized in part, changing icons and / or adopting a new theme. However, note that this application is not translated into French, but the English is easy to understand.

With Android 2.3

Among the simplest applications to take in hand, users who own a mobile device with the version of Android 2.3 or a little higher can find happiness in the app Smart AppLock.

Adopting a semblance of the interface in Material Design; with its straight lines, flat icon and side drawer, the Smart AppLock Android app is a bit more beautiful than the previous one, but the level of compatibility requested is higher. That said, this application is relatively fluid in use and also allows to lock one or more applications to choose from a drawing scheme or a password digit.

By tapping on the padlock (installed at the top right on the home page), you can instantly block access to all applications, or individually by clicking on one of them. As you explore the application settings, you’ll see several possibilities: lock type, application background color, allowed performance level, and an option to quit Smart AppLock quickly.


If this application does not work, try these alternatives, also compatible for Android 2.3:




With Android 4.0

If your mobile runs under a fairly advanced version of Android, the Android app called Magic AppLock is the least intrusive I’ve tested at this level. When the application is first launched, the first screen presents a selection of recommended applications to protect, in addition to listing all the others in the second vignette in a row. Once you have chosen the application or applications that you want to block, the second screen asks you to lock them by means of a four-digit scheme or password.


Before you reach the home screen of the application, the last and third configuration screen asks you to raise the rights of the application (so that it can interact with others), in addition to asking you if you want to enter a deblocking scheme or password when you uninstall an application. Rather useful, this allows a child not to uninstall an important application by mishandling! Once launched, you can find the locked applications listed on the home page, but also add by means of the icon in the form of a “+”.

With Android 6.0 or higher

The most popular app is probably Lock, more commonly called AppLock. As its name suggests, it locks applications and prevents anyone from accessing them, the only way is to know the key unlocking system.
