Unable to Scan card only on my Device

SDK/Library version: Latest Version
iOS Version and Device: iOS 11 On iPhone 8
Integration type and version: Cocoapods 1.1.1

Issue description :

I am trying to run a sample application using the framework. Earlier it worked fine but after iOS 11 installed on my Phone, scanning always seems to be blur and flash turns on which is so weird that it cannot even read anything from Card.

When it comes to other devices, SDK able to scan properly. Please let me know if you need any additional information.
