If you are upgrading to iOS 9.3, Apple has tightened the security and taken one step ahead. Apple has added one Feature in iOS 9.3 related to Privacy of your iPhone.
Ok, Once your Latest iOS is updated, you will be able to see if your device is managed/tracked by your organization or institute via MDM. The following messages will appear under About option as well as on Lock Screen of your iPhone.
About : This Phone is Supervised. “Company Name” can monitor your internet traffic and locate this device.
Lock Screen : This Phone is managed by your organization
Although its not a secret that most company-administered iPhones are locked down in some way, current iOS versions do not prominently indicate if this kind of control is taking place on a device. With iOS 9.3, Apple is giving the user ultimate transparency in how their device is being exposed to their employer.
Apple allows organizations to track iPhones via MDM deployment program, but users were not quite clear whether their device is being tracked or not. This confusion will be removed from iOS 9.3, and users will be clear on this matter.
This change will also help privacy-conscious iPhone users who switch between work and personal phones. It will be easier for people to juggle between devices without getting confused which is which and there will be a conscious understanding that this device is being supervised and the other isn’t.
