Is there a way to disable the phone from installing apps from unknown sources?
I know that it is possible by just going to.

settings->security->unchceck "unknown resources"

Unknown Sources

But when kids install apps, a dialog appears:


By just tapping on settings, they can Enable it again and install the application.

is there a way to disable it and the dialog won't come out or make it grey so it won't be clicked/tap it again? Without putting password on my Settings.

    Speaking of "Kids" the first things coming to mind are: 1) using a restricted profile for them, 2) using a specific "kid protection" app. For the latter be welcome to take a look at my corresponding app listings: Child protection and App Locker: Child protection.

If you have Android OS Lollipop and above, you should create a guest mode for anyone you wish to hand over your cell phone, you can define the rights in the guest mode.

  • How to create a guest mode? any tutorial site please?

  • Drag down the notification to the full then you will see a profile icon and besides that an edit icon (Pencil Icon), click that and you will be guided accordingly.
