TextRecognizer - совместимость на разных устройствах

Всем привет! Сделал приложение с TextRecognizer. Приложение прекрасно работает и определяет текст на Xiaomi Redmi4. На Asus zenfone max pro m1 камера запускается, но текст при нажатии кнопки не определяется. Предполагаю, проблема в том, что в приложении используется Camera (deprecated), а не Camera2. Пожалуйста, помогите разобраться.
