An update to the developer documentation shows new features that businesses can use to control how company phones are used. It includes an option to edit the home screen layout, editing which apps show up, and where they are positioned. Employers could place the Mail app in prime position, for example, or hide the Notes app.
Another control in the update is the ability to block individual App Store apps from being downloaded onto company phones. So if "Candy Crush" is becoming a problem, whoever manages the devices can make sure company phones are unable to run the app.
The new iOS 9.3 update also allow employers to change notification settings for your device. So if you thought you could hide notifications for the company Slack channel: think again. Now employers can stick it in the middle of your home screen and force notifications to show up on your lock screen too.
