AmazonGamesClient not initializing on some Android devices

Hello,

I'm unable to initialize the AmazonGamesClient on a Samsung Nexus S with Android 4.1.2.

The reason received in onServiceNotReady callback is: CANNOT_INITIALIZE and the result from AmazonGamesClient::initializeSession is:

ResponseCode: 24 ErrorCode: UNRECOVERABLE requestType: 0

The same application is initializing with success on a Samsung Galaxy S3 with Android 4.3.

Can you help me with an advice about solving this problem?

Regards
