HI- I got the Optimus G and the volume in call was so low I took it back and got the HTC One X+. A little thin for my liking but the volume was chunks better. I think these developers are getting away with total murder fooling the public with these horrible volume calls. Something big needs to be done. For all the good features with the Optimus G, but a terrible volume in call made me switch to HTC One X+. Now I think I'm going to get the HTC One(M7) when it comes out. Very depressing, I was so looking forward to the Z. I work in a gossip filled IT environment and HTC appears to be the way to go. I do not think even the Samsung Galaxy IV will be better than the HTC One based on call quality. Probably might check out the next Atrix or something to see if the in-call is better, but so far nothing beats the One.
