LingoTok - AI Language Tutor

为什么我这里一点声音都听不到？（设备音量已经是调到最大了）并且说话没反应

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!!!!

this app is very great and so fun
