   Hello together,
   I use the following code snippet to detect if I am on a simulator. So far I have not found any issues with it, maybe it helps you:

   export class DeviceInfo {
   	static deviceId(): string {
   		let deviceId = '';
   		if (global.isIOS) {
   			const systemInfo = new interop.Reference<utsname>();
   			uname(systemInfo);
   			deviceId = NSString.stringWithUTF8String(systemInfo.value.machine).toString();
   		} else {
   			deviceId = android.os.Build.BOARD;
   			if (!(deviceId && !deviceId.toLocaleLowerCase().includes('unknown'))) {
   				deviceId = android.os.Build.SERIAL;
   			}
   		}
   		return deviceId;
   	}
   	static isEmulator(): boolean {
   		if (global.isIOS) {
   			return DeviceInfo.deviceId() === 'i386' || DeviceInfo.deviceId() === 'x86_64';
   		} else {
   			const Build = android.os.Build;
   			return (
   				Build.FINGERPRINT.startsWith('generic') ||
   				Build.FINGERPRINT.startsWith('unknown') ||
   				Build.MODEL.includes('google_sdk') ||
   				Build.MODEL.includes('Emulator') ||
   				Build.MODEL.includes('Android SDK built for x86') ||
   				Build.MANUFACTURER.includes('Genymotion') ||
   				(Build.BRAND.startsWith('generic') && Build.DEVICE.startsWith('generic')) ||
   				'google_sdk' === Build.PRODUCT
   			);
   		}
   	}
   }
