Xperia Ray :: Phone Simply Does Not Register Touches

One major issue that has disaapointed me about my Xperia Ray since purchase is the "touch experience".So many times the phone simply does not register my touches and I find myself poking repeatedly at the same place. Now whats funny is that it does not seem like an outright case of attenuated sensitivity or something because at times the touch registers and at times it simply does not until you retry once or twice or so. On the other hand, the touch sensitive buttons at the bottom never seem to miss a touch. And when they its because I'v not touched them in the exact location due to the absence of backlighting.

But yes, the overall sensitivity of the screen does seem to be a noticibaly lower than other devices I'v used. And I'm not accounting for the missed touches when I say that.
