Precautions To Take Before Installing iOS 16.3 Beta
The reason being that Beta software is used for testing purposes. When the company introduces a new feature, they need to test it for a while. They usually release it to testers because they need their feedbacks. These feedbacks help the company to know what to change. It also helps them determine what to add and what to take out.
This is why in most cases; they make Beta testing an option for users to register. Registering for Beta testing means you understand the risk. And that you cannot hold the company responsible should anything go wrong. 
Due to this, most Beta testers have a separate device for that purpose. They usually do not use their main phone for that. Or they backup every important data before going ahead with the Beta update.
These are just precautions you need to take before making any Beta updates. It is either you get a separate device for the purpose of testing Beta operating systems. Or better still, make a full backup of all your data before updating.
Using your main personal device for such testing purposes. Can lead to either bricking your device completely. Or your device can lose functionalities in some areas. Beta operating systems can affect your camera, speaker. It can even affect your device network connections. In the worst of it all, your device can go completely off.
So, take extra precautions before you ever install any Beta software of your device.
