Talking App como hablar, la grabación de audio no funcionó en todos los dispositivos

Estoy desarrollando una aplicación como hablar tom, todo está funcionando bien sólo la grabación de audio haciendo problemas en algunos dispositivos, Audio también está funcionando bien en mi dispositivo hdpi, pero siempre que lo ejecute en samsung tab 7 o ficha 10 o cualquier otro teléfono, En algunos dispositivos su escuchar continuamente el audio y en algunos dispositivos no escuchan en absoluto, estoy usando código siguiente para la grabación audio.
