    I have been using HTC one M8. Till the recent upgrade, the application was working fine however now the audio quality is very poor even with the very strong internet - 5 MBPS incomming and 1.2 outgoing, I also use Samsung S3 and the call quality is very good using same internet. This has not been upgraded. Any one having solution?
