I had issues with viber and mobile voip ( voip application ) on the original sense rom when i got the phone new last time. Because of that and the advantages of custom roms, i went to CM based roms. It was great. Thing is i missed the sense look and feel....Long story short, i now have Renovate Rom with the kernel supplied with it. I am facing the same problems again. People on the other end cant hear me, and call connection is poor. A friend of mine said its due to sense 4+. Please do help me solve this, as i love the sense, just that this is whats putting me off...Thanks guys.
