Jelly Bean available for custom ROM developers [alpha ROM]

A while ago, the Sony Xperia™ News room shared an update on our plans to upgrade certain Xperia™ devices to Jelly Bean. Since then we have received quite a few requests from the Android™ developer community to release an earlier version of the Jelly Bean (JB) software for the developers. This way, advanced developers could try it out and evaluate it, in a similar way to how we did it last year with the ICS alpha release. Please note that there are several limitations to this alpha software, for instance the UI look and feel is not updated to final Sony Jelly Bean software. Read more after the jump!

Shoot great videos in all conditions with the new HDR functionality in Xperia™ Z

Have you ever tried to shoot a video of a scene that has a strong backlight, like when a person stands in front of a window or direct sunlight? Well, then you will know that it can be almost impossible to get the right exposure of all parts of the picture. Now with the HDR function of the Exmor RS™ image sensor in the new Xperia™ Z, you can get great videos and photos even in these high contrast scenes. For our implementation of HDR video, we use different exposures on every two lines of pixels, to create an optimal result, with really good contrasts. Read on as we explain more how this works!
