AWSCognito User getDetailHandler API not working on some android devices

Hi, we are working on signing in to AWSCognito for Android. In this getDetailHandler UI didn't work on some Android devices (noted in Samsung Tab 4.4.4 and MotoG3 V6.0.1 APILevel 23). It seems to work fine in MiPad version 4.4.4 and MotoG2 version 5.1 APILevel 22. In fact it works fine 10 days ago on all devices. Please let us know what the problem is and that would be helpful to us.
