What is a description file

What is the description file?

Description file is simply the configuration file of the iOS system. With this file, we can write a variety of setting information into Apple devices, including device security policies and access restrictions, and private network configuration.

Usually, most of the description files used by everyone are upgrade beta version or public beta version description files. But in fact, there are many practical description files. Let’s list them below.

1. Upgrade the iOS beta version or public beta system

Take the latest iOS12 system released for evaluation as an example. The iOS12 beta test version and public beta version have been released. Before the official version of the system, If ordinary users want to try out the new system, they can install the description file and then quickly upgrade online through OTA without flashing the phone.

However, we need to remind everyone that the beta version or public beta version is launched to collect bugs, and it is not recommended for novice users or main mobile phones to upgrade. If you must upgrade, it is recommended to choose the public beta version, which is relatively stable.

2. Block iOS system update reminder

The description file used to block iOS update reminder is essentially the Beta system description file of Apple TV. After installation, iPhone and iPad will not receive system updates due to the Apple TV description file, and there will be no reminder to update the system. No matter what your system version is, your phone will display the latest version, which is more suitable for older devices that no longer plan to upgrade the system.

Of course, if you want to unblock iOS system update reminders in the future, just delete the description file.

3. Child Mode

Faced with naughty children, iOS description files also have solutions. This description file disables in-app purchases, requires an iTunes Store password for all software purchases, and changes the device lock time to a maximum of 5 minutes. Even if a naughty child takes your mobile phone to play with it, there will be no additional consumption.

Of course, for the sake of children’s healthy growth, it is best to let them play with mobile phones as little as possible.
