+### startDeviceDetectionInterval
+Starts device detection interval, which is run on specified number of seconds. This allows detection of new attached devices, started emulators/simulators, detection when device/emulator/simulator is disconnected, etc.
+> NOTE: The interval is started automatically when you call `devicesService.initialize` without passing `skipDeviceDetectionInterval: true`.
+
+> NOTE: iOS Device detection interval cannot be stopped, so once started, it will always report connected/disconnected devices.
+
+* Definition
+```TypeScript
+startDeviceDetectionInterval({ detectionInterval?: number, platform?: string }): void
+```
+
+* Usage
+```JavaScript
+tns.devicesService.startDeviceDetectionInterval({ detectionInterval: 1000 });
+```
+
+### stopDeviceDetectionInterval
+Stops device detection interval started by `devicesService.initialize` or `devicesService.startDeviceDetectionInterval`.
+* Definition
+```TypeScript
+stopDeviceDetectionInterval(): void
+```
+
+* Usage
+```JavaScript
+tns.devicesService.stopDeviceDetectionInterval();
+```
+
+### startEmulatorDetectionInterval
+Starts emulator images detection interval, which is run on specified number of seconds. This allows detection of new installed emulator/simulator images.
+
+* Definition
+```TypeScript
+startEmulatorDetectionInterval({ detectionInterval?: number }): void
+```
+
+* Usage
+```JavaScript
+tns.devicesService.startEmulatorDetectionInterval({ detectionInterval: 1000 });

+
+### stopEmulatorDetectionInterval
+Stops device detection interval started by `devicesService.startEmulatorDetectionInterval`.
