Blocking the installation of new applications is useful when we give the phone to a child to play with. It happens that in our case the child sets unwanted applications from Play Store or - even worse - buy paid games. This can be blocked using a special application.

We recently showed you how to block app installation and uninstallation on iPhone and iPad. IN Apple devices it's easy because this feature is built into the restrictions options. Android unfortunately doesn't have this option, but you can use another method to block new app installations.

Step 1: Download the Smart AppLock app.

On Android smartphones you can install applications in two ways - using Play Store, as well as manually using APK file with the installer of the selected game or application. Both of these methods can be easily password locked using the Smart AppLock app.

Download Smart AppLock from Play Store

30 30 30 wouldyyyy all would wouldyy all all 30 all all all would all 30 all all all all all 30 would ally 30y all 30 all "Application block". Click the plus button at the bottom of the screen to display the screen additional services and applications in the block list.

Choosing these two options to do so without a PIN will not be able to access the Play Store (so you cannot install apps) and you cannot install the file APK applications(you will be prompted to enter your PIN).

That's not all. In case someone misses some kind of blocking (for example, installing an application remotely via a computer), it is worth activating the automatic blocking feature again installed applications. To do this, go to the Smart AppLock tab "Settings", and then select the option "Additional locks".
