Develop your own applications
You can create your own applications for the phone using an applicable software development kit (SDK).
You need to activate developer mode on the phone to be able to use it as a target for application development. Developer mode enables connectivity between the development host and the phone, and provides a few additional tools on the phone.
Select and Security > Developer mode , and activate Developer mode.
It is recommended that you do not activate developer mode, unless you intend to develop applications for the phone. Activating developer mode does not expose the phone to security risks, but you may accidentally delete important system files.
