"Regarding the speakerphone..."4.5 starson by slappy1313
Pros: Great sound, lots of features
Cons: speakers in the back
Summary: My speakerphone was also screeching like feedback and then I figured it out. If you turn off the Voice Clarity feature the speakerphone will work fine (even in the middle of a call). I almost believe that is a feature that isn't meant to be used with speakerphone and is maybe deactivated if speakerphone is turned on before a call is made. Regarding the rest of the phone, I love the sound it produces and the vivid screens. The phone has a very clear sound during calls. I'm hoping the battery works as described.
