The app is really buggy. 1, failed of connection, always happen. 2, back from screen autolock will lead to stuck forever 3, instruction language always jump to other languages 4, I'm learning Korean by Chinese, the model sometimes use Chinese character to pronounce Korean! that's totally horrible 5, voice recognition is terrible. Google refused to give the refund! that's bully and scam, the model and the app is far from production ready, I want my money back!!!!
