SAP Fiori Client Suddenly Close in IOS Device

Hello Experts,

We have successfully integrated  Cordova plugin with SAP UI5 application. Through the SAP Fiori Client we are opening the application in the iOS Mobile phone and iPad devices.

Currently we are experiencing unstable condition during scanning the QR code from the iOS device , the Fiori Client will close suddenly after scanning the QR Code and Scanning is very fast.

When we scan continuous more then 5 times the Fiori Client Apps will close automatically and need to login again.

For 2 or 3 times scanning the results are fine.

Note: We try to do in Android  device also the results are same.

Can you please give some idea on this.

Thanks,

Pad
