If you want to have the best experience on your Xperia Ray, I would ask you to downgrade to Gingerbread (Android 2.3) from ICS (Ice Cream Sandwich). I have tested ICS (Ice Cream Sandwich) on my device, and never found the desired experience. Select Gingerbread, it’s fast and that’s the sole reason for me sticking to Gingerbread over the ICS.
