Oh there most certainly is, and it is glaringly obvious to anyone who doesn't have their head stuck in the sand.
Do some basic research and look at all of the top new phones released in 2012. Save your silly charts showing millions of blackberry users in India or some other nonsense that is 100% irrelevant. Look at new 2012 releases and open your eyes.

You are simply living in a fantasy world if you believe screens on smart phones are not getting bigger. Let's see how many major smart phones are built under 4 inches in 2013.

You don't need to be an expert to notice cell phone companies are making larger and larger screens (INCLUDING apple). Anyone who isn't completely oblivious to the real world can notice that.
Really.
It has come to a point where the android OEMs are now competing with each other on screen sizes, and only screen sizes, because almost everything on the spec sheet is not identical across their phones.
And contrary to popular belief, stuffing a larger screen on your phone doesn't make it more innovative
If I were an android oem, I would be asking myself why android phones only get 4 hours of screen time on average
