Last year Sony announced that 2011 xperia devices wont be upgraded to new JB just because the device hardware does not support JB OS.
Recently Sony released new Xperia E with 4.1 JB system.
Now I have Xperia Ray 2011 model and when I checked Xperia E hardware, I was shocked.
Here is the hardware comparison:
Xperia Ray
Xperia E
I guess, just because of the low internal memory, Ray is not getting JB update.
This is discrimination and injustice
Solved! Go to Solution.
So at least optimize the ICS
+
modernize applications (old design Gingerbread).
You can find more information about software updates and reasons to decisions on our product blog.
