Hwcallrecorder

Dear all,

Please help, I followed the online instruction to root my mediapad x2 (GEM-702L) by SuperSU, and process to install the Hwcallrecorder function, I purchased this machine in Hong Kong while I'm on travel ...

anyway, cut it short, I even change all the permission for the folder and app, but i still can't get it work, what shall I do?

Thanks
