Description

From the listing uploaded by “appupdater”.

"When you pass a smartphone to others, other parts can be seen and other concerns". SecureScreen eliminates such anxiety. With this application, you can block touching content on screen and moving to other apps. Please note that this app is NOT alternative for lock screen. You can use this when you want to show your friends only one screen. □ Usage · I want to show travel photos but when I do not want to show other photos in the image folder. · It is necessary to show a specific mail, but it is troublesome to see other mails. To further increase the effect Turn on the screen fixation from [Settings] application -> [security] -> [Screen pinning] and turn ON the [Require password (depending on the locking method used) before releasing the screen fix I will recommend it. You can still use the application even if [Fixed screen] is OFF, but further safety can be expected by the above setting.
