Leon BLOWS!!! why can't I record voicecalls?

[Eve Xoxo]

This phone gets overwhelmed and freezes up or loses speed way too fast! Aside from that, I can no longer record calls using ANY of the call recording apps. it will only record audio that comes through the speakerphone microphone...which BLOWS because on all other versions, or models of device and softwares, the CALLRECORDIMG APPS WORKED BEAUTIFULLY...
I've already rooted my phone but still notthing.. idk if its the 5.0.2 or the leon but if anyone knows a way around this please let me know... cuz so far the LG Leon, in my opinion, is a Piece O' Sh**!
