Description

ISL Light for iOS now supports live screen sharing from iOS devices (iOS 11.x.x and later). Operators can connect to iPhone, iPad or iPod device and view real-time screen changes. ISL Light for iOS is utilizing Apple's screen recording and broadcast capabilities, that were made available in iOS 11.

When ISL Light for iOS user joins the session or connects to remote device, a set of instructions will be displayed in chat, that will guide user to start broadcasting screen to the operator.

2. To start screen sharing, go to "Control Center" of iOS device (double tap "Home" button or swipe from the bottom of the screen) and press on "Screen Recording" icon (hold for around 2 seconds). This will bring up the Screen recording menu, where you select "ISL Light" from the list, then click on "Start broadcast".

4. To stop screen sharing, go back to Control Center of your iOS device (double tap "Home" button or swipe from the bottom of the screen) and tap on Screen recording icon to stop recording screen.
