The error has nothing to do with the device. These logs are not from our demo app (different namespace). If you try with our demo app it'll work fine.
You're not correctly following the documentation that's why it's failing. The error means the engine is failing to find mrz.traineddata. check https://github.com/DoubangoTelecom/ultimateMRZ-SDK?tab=readme-ov-file#Getting-started-Adding-the-SDK-to-your-project-Android
