You can also help safeguard your device by downloading apps only from trusted sources, such as the BlackBerry World 
storefront.
When you open an app for the first time, your device might display a list of the files and features that the app wants to 
access. If something doesn't seem right to you, you can reject the app's request to access an item. For example, you might 
download a game that requests access to your messages, which might make sense if the game includes a feature to share 
your game score. However, if you aren't comfortable with the game having the ability to compose and view your email 
messages, you can turn off access to messages or delete the app. You can view or change permissions for most apps in 
your device settings.
For some apps, when you install the app, you are prompted to accept or decline all of the requested permissions. If you 
decline, the prompt will appear again the first time you open the app. You can't change the application permissions later 
unless you delete and reinstall the app.
Change or view app permissions
For some apps, if you turn off permissions, the app might not work as you expect. If an app isn’t working as you expect it to, 
consider turning on some or all of the app permissions.
The Run When Minimized application permission setting lets an app continue performing tasks after you minimize the app 
on your BlackBerry device.To help extend the life of your battery, consider turning off the Run When Minimized permission 
for apps on your device.
